    Although female sexual dysfunction is a problem with low priority, it can have a profound impact on quality of life. In women, the cycle of sexual response begins in the brain, where a memory, an image, a scent, music, or a fantasy acts as a trigger to prompt sexual arousal. Thus, the brain is really the key and starting place for treatment of sexual dysfunction. Decreased libido, altered arousal, inability to achieve orgasm, and dyspareunia are the four broad types of sexual dysfunction in women. Decreased libido, thought to be related to androgenic hormones, results in delayed or altered arousal, decreased vaginal lubrication and dilation, delayed or absent orgasm, and pain or dyspareunia, which can lead to an aversion to sexual experiences.

    In the past, medical attitudes to female sexuality were grotesque, reflecting the anxiety and hypocrisy of the times. In the medieval world, the population feared hunger, the devil, and women, being particularly outraged and threatened by normal female sexuality. The 19th century attitude was no better as academics confirmed the lower intellectual status of women, particularly if they ventured into education. The medical contribution to this prejudice was shocking, with gynaecologists and psychiatrists leading the way designing operations for the cure of the apparently serious contemporary disorders of masturbation and nymphomania. The gynaecologist, Isaac Baker Brown (1811-1873), and the distinguished endocrinologist, Charles Brown-Séquard (1817-1894) advocated clitoridectomy to prevent the progression to masturbatory melancholia, paralysis, blindness and even death. Even after the public disgrace of Baker Brown in 1866-1867, the operation remained respectable and widely used in other parts of Europe. This medical contempt for normal female sexual development was reflected in public and literary attitudes. There is virtually no novel or opera in the last half of the 19th century where the heroine with "a past" survives to the end. The wheel has turned full circle and in the last 50 years new research into the sociology, psychology and physiology of sexuality has provided a greater understanding of decreased libido and inadequate sexual response in the form of hypoactive sexual desire disorder (HSDD). This is now regarded as a disorder worthy of treatment.

    Sexual dysfunctions have been the most prevalent group of sexual disorders and include a large number of populations of both sexes.The research of sexual behavior and treatment of women with sexual distress arises many questions related to differences in sexual response of men and women. The conceptualization of this response in modern sexology has changed over time.The objective of our paper was to present the changes and evolution of the female's sexual response concept in a summarized and integrated way, to analyze the expanded and revised definitions of the female sexual response as well as implications and recommendations of new approaches to diagnostics and treatment according to the established changes.The lack of adequate empirical basis of the female sexual response model is a critical question in the literature dealing with this issue. Some articles report that linear models demonstrate more correctly and precisely the sexual response of women with normal sexual functions in relation to women with sexual dysfunction. Modification of this model later resulted in a circular model which more adequately presented the sexual response of women with sexual function disorder than of women with normal sexual function.The nonlinear model of female sexual response constructed by Basson incorporates the value of emotional intimacy, sexual stimulus and satisfaction with the relationship. Female functioning is significantly affected by multiple psychosocial factors such as satisfaction with the relationship, self-image, earlier negative sexual experience, etc. Newly revised, expanded definitions of female sexual dysfunction try to contribute to new knowledge about a highly contextual nature of woman's sexuality so as to enhance clinical treatment of dysfunctions.The definitions emphasize the evaluation of the context of women's problematic sexual experiences.

    Sex is a motive force bringing a man and a woman into intimate contact. Sexuality is a central aspect of being human throughout life and encompasses sex, gender identities and roles, sexual orientation, eroticism, pleasure, intimacy, and reproduction. Sexuality is experienced and expressed in thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles and relationships. Though generally, women are sexually active during adolescence, they reach their peak orgasmic frequency in their 30 s, and have a constant level of sexual capacity up to the age of 55 with little evidence that aging affects it in later life. Desire, arousal, and orgasm are the three principle stages of the sexual response cycle. Each stage is associated with unique physiological changes. Females are commonly affected by various disorders in relation to this sexual response cycle. The prevalence is generally as high as 35–40%. There are a wide range of etiological factors like age, relationship with a partner, psychiatric and medical disorders, psychotropic and other medication. Counseling to overcome stigma and enhance awareness on sexuality is an essential step in management. There are several effective psychological and pharmacological therapeutic approaches to treat female sexual disorders. This article is a review of female sexuality. PMID:26330647

    The clitoris may be the most pivotal structure for female sexual pleasure. While its significance has been reported for hundreds of years, no complete anatomical description was available until recently. Most of the components of the clitoris are buried under the skin and connective tissues of the vulva. It comprises an external glans and hood, and an internal body, root, crura, and bulbs; its overall size is 9-11 cm. Clitoral somatic innervation is via the dorsal nerve of the clitoris, a branch of the pudendal nerve, while other neuronal networks within the structure are complex. The clitoris is the center for orgasmic response and is embryologically homologous to the male penis. While the source of vaginal eroticism might or might not be exclusively clitoral stimulation, it is necessary to understand the intricate anatomy of the organ to assess the data in this regard. Ultimately, sexual enjoyment entails a balance of physical and emotional factors and should be encouraged. © 2015 Wiley Periodicals, Inc.

  11. Sexual responsiveness is condition-dependent in female guppies, but preference functions are not

    Full Text Available Abstract Background Variation in mate choice behaviour among females within a population may influence the strength and form of sexual selection, yet the basis for any such variation is still poorly understood. Condition-dependence may be an important source of variation in female sexual responsiveness and in the preference functions for male display traits that she expresses when choosing. We manipulated food intake of female guppies (Poecilia reticulata, and examined the effect on several measures of condition and various components of mate choice behaviour. Results Diet significantly influenced four measures of female condition: standard length, weight, reproductive status and somatic fat reserves. Diet also significantly affected female sexual responsiveness, but not preference functions: females in good and poor condition prefer the same males. Conclusions Variation in female condition within populations is therefore unlikely to influence the direction of sexual selection imposed by female choice. It may, however, influence the strength of sexual selection due to its effects on female responsiveness. The relative importance of female choice as a sexually selective force may also covary with female condition, however, because low responsiveness may result in sneak copulations being relatively more important as a determinant of the paternity of offspring. Differences among populations in mean condition may also influence geographic differences in the strength of sexual selection.

  13. [Female sexual dysfunction].

    Female sexual problems are common, frequently overlooked and have a significant impact on the lives of women. Research in the last decade has brought to the understanding and recognition of a number of standpoints, mainly the broad range of normative function. In 2003, the American Urological Association Foundation convened an international committee of experts in the field of women's sexuality, to reconsider the existing definitions of women's sexual dysfunction. Based on the circular response cycle developed by Basson, the group emphasized motivations that might move a woman from being sexually "neutral" to making a decision to be sexual with her partner, as a normative alternative to the need for spontaneous sexual desire as the trigger for sexual behavior. Etiology may stem from medical as well as psychological factors, thus assessment must include a complete evaluation. Treatment includes psycho-education, improvement of interpersonal communication, cognitive behavioral treatment and elucidation and treatment of medical problems, if necessary. Several pharmacological treatments are under investigation, with modest results and uncertainties about their long term safety. This review presents the female sexual response as it is understood today and the current diagnostic and therapeutic understandings and directions.

    Whether erotic films made by women are more arousing for women than erotic films made by men was studied. Forty-seven subjects were exposed to both a woman-made, female-initiated, and female centered, erotic film excerpt. Photoplethysmographic vaginal pulse amplitude was recorded continuously. Self-report ratings of sexual arousal and affective reactions were collected after each stimulus presentation. Contrary to expectation, genital arousal did not differ between films, although genital response to both films was substantial. Subjective experience of sexual arousal was significantly higher during the woman-made film. The man-made film evoked more feelings of shame, guilt, and aversion. Correlations between subjective experience of sexual arousal and photoplethysmographic measures of sexual arousal were nonsignificant. The largest contribution to female sexual excitement might result from the processing of stimulus-content and stimulus-meaning and not from peripheral vasocongestive feedback.

  15. Female social response to male sexual harassment in poeciliid fish: a comparison of six species.

    Sexual harassment is common among poeciliid fish. In some fishes, males show a high frequency of sneak copulation; such sexual activity is costly to the females in terms of foraging efficiency. In mosquitofish (Gambusia holbrooki), when males are present, the distance between females tends to decrease, and this behavior has been interpreted as an adaptive strategy to dilute the costs of male sexual activity. In this study, the tendency to reduce distance in the presence of a male has been investigated in females of six poeciliid species (Girardinus metallicus, Girardinus falcatus, G. holbrooki, Poecilia reticulata, Xiphophorus hellerii, and Xiphophorus mayae) that exhibit different male mating strategies and different levels of sexual activity. Results revealed large interspecific differences in the pattern of female aggregation. Females of species with a high frequency of sneak copulations tended to reduce their social distance in the presence of a male. By contrast, species that rely mainly on courtship showed little or no variation in social distance. The proportion of sneak copulations predicts the degree of variation in female social response, but the amount of total sexual activity does not, suggesting that the change in females' social distance when a male is present may indeed serve to reduce the costs of male sexual harassment.

  17. Measuring Implicit Sexual Response Biases to Nude Male and Female Pictures in Androphilic and Gynephilic Men.

    Timmins, Liam; Barnes-Holmes, Dermot; Cullen, Claire

    2016-05-01

    Snowden, Wichter, and Gray (2008) demonstrated that an Implicit Association Test and a Priming Task both predicted the sexual orientation of gynephilic and androphilic men in terms of their attraction biases towards pictures of nude males and females. For both measures, relative bias scores were obtained, with no information on the separate response biases to each target gender. The present study sought to extend this research by assessing both relative and individual implicit biases using the Implicit Relational Assessment Procedure (IRAP). An explicit measure screened for men with androphilic (n = 16) or gynephilic (n = 16) orientations on the dimensions of "sexual attraction," "sexual behavior," "sexual fantasies," "hetero/gay lifestyle," and "self identification." The IRAP involved responding "True" or "False" to pictures of nude males and females as either attractive or unattractive. Participants were required to respond in a manner consistent with their reported sexual orientation for half of the IRAP's test blocks and inconsistent for the other half. Response latencies were recorded and analyzed. The IRAP revealed a non-orthogonal pattern of biases across the two groups and had an excellent ability to predict sexual orientation with areas under the curves of 1.0 for the relative bias score and .94 and .95 for the bias scores for the male and female pictures, respectively. Correlations between the IRAP and explicit measures of sexual orientation were consistently high. The findings support the IRAP as a potentially valuable tool in the study of sexual preferences.

    This cross-sectional study aimed to determine the construct of the phases of the female sexual response cycle (SRC) in women with hypertension and their association with the duration of hypertension and types of antihypertensive agents. The sexual response phases were measured with a validated Malay version of the Female Sexual Function Index (FSFI). The correlations structure of the items of the SRC's phases (i.e. desire, arousal, orgasm, satisfaction and pain) was determined using principal component analysis (PCA), with varimax rotation method. The number of factors obtained was decided using Kaiser's criteria. A total of 348 hypertensive women were recruited for this study. Four constructs were extracted in the analysis of all subjects. Using the factor analysis, the six domains (i.e. sexual desire, arousal, etc.) of the women's SRC among hypertensive women merged into 4 constructs. They were composed of (i) sexual desire and arousal, (ii) orgasm and sexual satisfaction, (iii) vaginal lubrication and (iv) sexual pain. Interestingly, vaginal lubrication stood out alone as one construct, compared to the non-hypertensive women. It was also observed that the duration of hypertension, beta blocker and diuretic antihypertensive medications had different influence on the SCR (in terms of constructs). Duration of hypertension and types of antihypertensive drugs may affect the components of the SRC. A clear understanding would help the clinician in strategizing the treatment approach of sexual dysfunction in women with hypertension. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available This paper results from an investigation on the discourse of female sexuality carried by women's magazines in the years 2005 and 2006. 'Claudia' and 'Mulher dia-a-dia' were the documents analyzed through a qualitative investigative approach. The data construction was undertaken through critical discourse analysis, and female sexuality was approached from a constructivist perspective. The main results showed that the discursive conventions present in the reports gave shape to dual positions on contemporary Western sexual dynamics, such as: adoption of symmetrical sexual practices versus continuation of asymmetrical sexual practices; female sexual autonomy versus female sexual dependency; activeness versus passiveness; female pleasure versus male pleasure. Thus, we argue that sexuality remains doubly informed by hegemonic standards in force within society.

The article analyses female sexuality in the light of hormonal status. Administration of sexual steroids during pregnancy and sexual differentiation High doses of gestagens, especially those with high androgen activity, widely used against miscarriages may lead to tomboys, but without differences in sexual orientation. However, it has been observed that the frequency of bisexual and lesbian women is higher in women with congenital adrenogenital syndrome. Hormones sexual desire and sexuality during menstrual cycle It has been established that sexual desire, autoeroticism and sexual fantasies in women depend on androgen levels. There are a lot of reports claiming that sexual desire varies during the menstrual cycle. Hormonal contraception and sexuality Most patients using birth control pills present with decreased libido. But, there are reports that progestagens with antiandrogenic effect in contraceptive pills do not affect sexual desire. Hormonal changes in peri- and postmenopausal period and sexuality Decreased levels of estrogen and testosterone in older women are associated with decreased libido, sensitivity and erotic stimuli. Sexuality and hormone replacement therapy Hormonal therapy with estrogen is efficient in reference to genital atrophy, but not to sexual desire. Really increased libido is achieved using androgens. Also, therapy with dehydroepiandrosterone (DHEA and tibolone have positive effects on female libido. Conclusion Effect of sexual steroids on sexual sphere of women is very complex. The association between hormones and sexuality is multidimensional, as several hormones are important in regulation of sexual behaviour. Still, it should be pointed out that sexuality is in the domain of hormonal, emotional

    2014-08-01

    Hypoactive sexual desire disorder (HSDD) is the most commonly described form of female sexual dysfunction. There is currently no pharmacological therapy approved to treat HSDD, and therefore, there is an unmet medical need for the development of efficacious treatment alternatives. Flibanserin is a novel, non-hormonal drug for the treatment of HSDD in pre- and postmenopausal women, although the application submitted to the U.S. Food and Drug Administration by Sprout Pharmaceuticals is only for premenopausal women. Flibanserin works by correcting an imbalance of the levels of the neurotransmitters that affect sexual desire. More specifically, flibanserin increases dopamine and norepinephrine, both responsible for sexual excitement, and decreases serotonin, responsible for sexual inhibition. Clinically, flibanserin has exhibited some encouraging results in terms of its ability to increase the frequency of satisfying sexual events, and the intensity of sexual desire. However, adverse events such as dizziness, nausea, fatigue and somnolence, typical of a centrally acting drug, are also frequently related to flibanserin treatment.

    2017-09-01

    Disgust has recently been implicated in the development and maintenance of female sexual dysfunction, yet most empirical studies have been conducted with a sexually healthy sample. The current study contributes to the literature by expanding the application of a disgust model of sexual functioning to a clinically relevant sample of women with low sexual desire/arousal and accompanying sexual distress. Young women (mean age = 19.12 years) with psychometrically defined sexual dysfunction (i.e., female sexual interest/arousal disorder [FSIAD] group) and a healthy control group were compared in their affective (i.e., facial electromyography [EMG] and self-report) and autonomic (i.e., heart rate and electrodermal activity) responses to disgusting, erotic, positive, and neutral images. Significant differences were predicted in responses to erotic images only. Specifically, it was hypothesized that the FSIAD group would display affective and autonomic responses consistent with a disgust response, while responses from the control group would align with a general appetitive response. Results largely supported study hypotheses. The FSIAD group displayed significantly greater negative facial affect, reported more subjective disgust, and recorded greater heart rate deceleration than the control group in response to erotic stimuli. Greater subjective disgust response corresponded with more sexual avoidance behavior. Planned follow-up analyses explored correlates of subjective disgust responses.

    Full Text Available Sexual behavior is a result of interaction of biology and psychology. Sexual excitement of the female can be triggered by stimulation of erotogenic areas; part of which is the clitoris. Female circumcision is done to minimize sexual desire and to preserve virginity. This procedure can lead to psychological trauma to the child; with anxiety, panic attacks and sense of humiliation. Cultural traditions and social pressures can affect as well the unexcised girl. Female circumcision can reduce female sexual response, and may lead to anorgasmia and even frigidity. This procedure is now prohibited by law in Egypt.

    Male signaling influences both female choice and male-male competition. Although male signaling characteristics and female preferences have been shown to coevolve in many species, few studies have examined whether male signal characteristics and male receiver responses related to male-male competition also coevolve. The present study tested the hypothesis that male and female signal receiver preferences may coevolve in parallel for frogs in the genus Babina by comparing the acoustic structure of male advertisement calls of four closely related and geographically isolated Babina species. Then we assessed the behavioral responses of both male and female B. daunchina (Emei music frog) to male call playbacks from each of the four species. The results support the hypothesis that male and female signal receiver preferences have coevolved in this species. Specifically, both male and female B. daunchina respond strongly to the heterospecific calls of B. hainanensis, suggesting that preexisting biases exist in both females and males. Both male and female individuals showed a slight response to the calls of B. adenopleura while no response was evoked by the calls of B. lini. The manifestation of similar response profiles in male and female B. daunchina to the calls of the four species support the idea that male and female signal receiver preferences evolved in parallel and that the origin of these receiver biases reflects adaptations dependent on the same neural and cognitive systems in both sexes.

    For the last three decades, male and female sexual responses have been conceptualized as similar, based on separated and sequential phases as proposed by the models of Masters and Johnson (1966) and Kaplan (1979) model. However, there is a growing debate around the need to conceptualize female sexual response and the classification of sexual dysfunction in women, in view of the upcoming editions of the DSM and ICD. The aim of this study was to test, using structural equation modeling, five conceptual, alternative models of female sexual function, using a sample of women with sexual difficulties and a sample of women without sexual problems. A total of 1993 Portuguese women participated in the study and completed a modified version of the Female Sexual Function Index. Findings suggested a four-factor solution as the model that best fit the data regarding women presenting sexual difficulties: (1) desire/arousal; (2) lubrication; (3) orgasm; (4) pain/vaginismus. In relation to sexually healthy women, the best model was a five-factor solution comprising of (1) desire; (2) arousal; (3) lubrication; (4) orgasm; and (5) pain/vaginismus. Discriminant validity between factors was supported, suggesting that these dimensions measure distinct phenomena. Model fit to the data significantly decreased in both samples, as models began to successively consider greater levels of overlap among phases of sexual function, towards a single-factor solution. By suggesting the overlap between pain and vaginismus, results partially support the new classification that is currently being discussed regarding DSM-5. Additionally, results on the relationship between sexual desire and arousal were inconclusive as sexually healthy women were better characterized by a five-factor model that considered the structural independence among these factors, whereas women with sexual difficulties better fit with a four-factor model merging sexual desire and subjective sexual arousal.

    Nationalist movements are emerging today everywhere in the world. Many of them display a high level of aggression and a negative attitude toward sexuality and especially female sexuality. Along with this, erotic fiction with a sadomasochistic orientation has achieved great success and has hundreds of millions of readers in the world. This collective fantasy allows some integration of aggression in sexual life while questioning liberal morality and its equality in gender roles and conservative morality and its idea of control over passion. Both phenomena may represent different responses to the appearance of a new female sexuality threatening the social structure we know.

    The intent of the study was to obtain data on the incidence of female sexual fantasy and on the relationship of background, personality, and attitudinal factors to the quantity of sexual fantasies. The participants were 102 university women students between the ages of 19 and 45 yr. An original Female Sexual Fantasy Questionnaire, a short form of the Attitude Toward Women Scale, the 16 PF, and the background variables of age, sexual experience, marital status, and religion provided data for the analysis. Conclusions were that 99% of the women engaged in sexual fantasy at least occasionally and that age, sexual experience, anxiety, independence, and liberal attitudes toward women are all related to frequency of sexual fantasy.

    Urinary incontinence is a common problem among women and it is estimated that between 15 and 55% of them complain of lower urinary symptoms. The most prevalent form of urinary incontinence is associated with stress, followed by mixed urinary incontinence and urge urinary incontinence. It is a symptom with several effects on quality of life of women mainly in their social, familiar and sexual domains. Female reproductive and urinary systems share anatomical structures, which promotes that urinary problems interfere with sexual function in females. This article is a review of both the concepts of female urinary incontinence and its impact on global and sexual quality of life. Nowadays, it is assumed that urinary incontinence, especially urge urinary incontinence, promotes anxiety and several self-esteem damages in women. The odour and the fear of incontinence during sexual intercourse affect female sexual function and this is related with the unpredictability and the chronicity of incontinence, namely urge urinary incontinence. Female urinary incontinence management involves conservative (pelvic floor muscle training), surgical and pharmacological treatment. Both conservative and surgical treatments have been studied about its benefit in urinary incontinence and also the impact among female sexual function. Unfortunately, there are sparse articles that evaluate the benefits of female sexual function with drug management of incontinence.

    Yoga is a popular form of complementary and alternative therapy. It is practiced both in developing and developed countries. Female sexual dysfunctions are common and do not always get adequate clinical attention. Pharmacotherapies for treating female sexual dysfunctions are available but suffer from drawbacks such as poor compliance, low efficacy, and side effects. Many patients and yoga protagonists claim that it is useful in improving sexual functions and treating sexual disorders. To establish the effect yoga can have on female sexual functions. We recruited 40 females (age range 22-55 years, average age 34.7 +/- 8.49 years) who were enrolled in a yoga camp and were given a standardized questionnaire named Female Sexual Function Index (FSFI) before and after the 12 weeks session of yoga. FSFI scores. It was found that after the completion of yoga sessions; the sexual functions scores were significantly improved (P 45 years) compared with younger women (age Yoga appears to be an effective method of improving all domains of sexual functions in women as studied by FSFI.

    Full Text Available Early life events induce alterations in neural function in adulthood. Although rearing in an enriched environment (EE has a great impact on behavioral development, the effects of enriched rearing on sociosexual behavior remain unclear. In this study, we investigated the effects of rearing in an EE on male copulatory behavior and its underlying neurobiological mechanisms in Wistar-Imamichi rats. Three-week-old, recently weaned rats were continuously subjected to a standard environment (SE or an EE comprised of a large cage with several objects, such as toys, tunnels, ladders, and a running wheel. After 6 weeks, rats reared in an EE (EE rats showed decreased sexual activity compared with rats reared in a SE (SE rats. This included a lower number of ejaculations and longer latencies in three consecutive copulatory tests. In addition, EE rats showed decreased emotional responsiveness and less locomotor behavior in an open field. In a runway test, on the other hand, sexual motivation toward receptive females in EE males was comparable to that of SE males. Furthermore, following exposure to a female, increases in serotonin levels in the nucleus accumbens and the striatum were significantly suppressed in EE males, whereas dopaminergic responses were similar between the groups. Female-exposure-induced increases in the levels of plasma corticosterone and testosterone were also suppressed in EE rats compared to SE rats. These data suggest that rearing in an EE decreases male copulatory behavior, and serotonin and hormonal regulating systems may regulate the differences in sociosexual interactions that result from distinct rearing environments.

    Full Text Available Background: The pursuit of sexual pleasure is a key motivating factor in sexual activity. Many things can stand in the way of sexual orgasms and enjoyment, particularly among women. These are essential issues of sexual well-being and gender equality. Objective: This study presents long-term trends and determinants of female orgasms in Finland. The aim is to analyze the roles of factors such as the personal importance of orgasms, sexual desire, masturbation, clitoral and vaginal stimulation, sexual self-esteem, communication with partner, and partner’s sexual techniques. Design: In Finland, five national sex surveys that are based on random samples from the central population register have been conducted. They are representative of the total population within the age range of 18–54 years in 1971 (N=2,152, 18–74 years in 1992 (N=2,250, 18–81 years in 1999 (N=1,496, 18–74 years in 2007 (N=2,590, and 18–79 years in 2015 (N=2,150. Another dataset of 2,049 women in the age group of 18–70 years was collected in 2015 via a national Internet panel. Results: Contrary to expectations, women did not have orgasms that are more frequent by increasing their experience and practice of masturbation, or by experimenting with different partners in their lifetime. The keys to their more frequent orgasms lay in mental and relationship factors. These factors and capacities included orgasm importance, sexual desire, sexual self-esteem, and openness of sexual communication with partners. Women valued their partner’s orgasm more than their own. In addition, positive determinants were the ability to concentrate, mutual sexual initiations, and partner’s good sexual techniques. A relationship that felt good and worked well emotionally, and where sex was approached openly and appreciatively, promoted orgasms.

    Female genital mutilation (FGM), otherwise known as female genital cutting (FGC), is currently very topical and has become a significant global political issue. The impact of FGM on the lives of women and girls is enormous, as it often affects both their psychology and physical being. Among the complications that are often under-reported and not always acknowledged is female sexual dysfunction (FSD). FSD presents with a complex of symptoms including lack of libido, arousability and orgasm. This often occurs in tandem with chronic urogenital pain and anatomical disruption due to perineal scarring.To treat FSD in FGM each woman needs specifically directed holistic care, geared to her individual case. This may include psychological support, physiotherapy and, on occasion, reconstructive surgery. In many cases the situation is complicated by symptoms of chronic pelvic pain, which can make treatment increasingly difficult as this issue needs a defined multidisciplinary approach for its effective management in its own right. The problems suffered by women with FGM are wholly preventable, as the practice need not happen. The current global momentum to address the social, cultural, economic and medical issues of FGM is being supported by communities, governments, non-governmental agencies (NGOs) and healthcare providers. It is only by working together that the practice can be abolished and women and girls may be free from this practice and its associated consequences.

    India was the context for this discussion of female sexuality, rigid social norms, women's strategies for resistance, the evolution of norms from colonial India, prostitution, myths, and self-help women's activities. Sexuality is a changing set of ideas, and women have contributed to the redefinition. The biological view without consideration of the sociocultural and historical influences proscribes what is deviant and may be used to reinforce patriarchy and colonialism. Management and control of sexuality has been influenced by class, religion, caste, and ethnicity. During the colonial period, women's sexuality and treatment was challenged by the missionaries. The abolishment of "sati" as a traditional practice was used by the British to expand their rule and control over a wider regional area. Attempts were also made to regulate prostitution as means of protecting the health of the British army. The law requiring registration, examination, and commitment for treatment of prostitutes was not adhered to by the women involved. The notion of mothers as irresponsible came into being about 1900, and encouraged abandonment of traditional child- rearing ways for the Western standard of health and hygiene, and lifestyle. In Bengal, motherhood and mother qoddesses became the symbol of the liberation movement. The maternal role could be strengthened through education. The notion of mother and nationhood was supported by the women's movement in Great Britain and the US through positive eugenics ideas of quality race, which supported the ruling elite of British and Indians. Thus, the high class women were to be protected from early marriage, and encouraged to produce children fit to govern; the poor were to be protected from prostitution and overpopulation. Post colonial ideas about sexuality reflected a number of influences both from within and outside India. Health was a focus, and program targets were those who were outside the norm: women with too many children

    Using the Female Sexual Function Index (FSFI) for investigating female sexual function has become widespread. A score of 26.5 has been suggested as delineating 'functional' from 'dysfunctional' women. This study aimed to understand in greater detail what contributes to changes in women's FSFI scores while their partners are taking oral erectile medications for erection problems. Couples randomized to receive two erectile medications for two 3-month phases, completed questionnaires. FSFI scores were augmented by individual interviews at baseline, 3 and 6 months, in order to better understand what the scores meant in the context of ED medication use. In all, 50% of the women scored dysfunctional' women recorded low FSFI scores solely as a result of their partner's ED. Overall, 22% were still 'dysfunctional' at 6 months, but one third of these appeared 'functional' at 3 months. A further group of women continued to record low scores despite reporting much improved sexual satisfaction. The women's interviews elaborate on their FSFI results, with five themes emerging to provide more clarity about the relative changes seen in a prospective study situation, and potentially in clinical practise contexts. The increasing use of questionnaires to determine sexual function should be supplemented with good clinical interviewing. The interview details explain how FSFI fluctuations occurred and contain clinical implications for research and practise in the area of couple's sexuality.

    Health care providers must recognize the specific challenges and rewards of providing services for adolescents. Quality care begins with the establishment of trust, respect, and confidentiality between the health care provider and the adolescent. Data suggest that the normal age for beginning puberty is decreasing, which has important clinical, educational, and social implications. The health care provider should be aware of the broad range of potential sexual behaviors involving adolescents, as well as the teen's acceptance of such behaviors, often dictated by age, gender, culture, and education. When providing gynecologic care to adolescent girls, the physician should not only provide contraception and screen for sexually transmitted diseases but should contribute to the development of the patient's sexual health. Especially when providing care for the younger teen, the health care provider must focus on involving a member of the family or another significant adult to provide needed support and guidance. Anticipatory guidance for parents should focus on assessing their parenting styles and promoting supervision. Although parents should strive to maintain open communication with their adolescents, they may not accurately estimate the sexual activity of and the sexual risk for their teenage children. Parents need to be encouraged to consider the implications of their own sexual behaviors. The provider should attempt to foster a comfortable environment in which youth may seek help and support for appropriate medical care while reserving the right to disclose their sexual identity when ready. Health care professionals cannot exclude heterosexual behavior on the basis that a young woman self-identifies as homosexual. Her reported sexual behaviors may not indicate her sexual orientation. Self-definition of sexual orientation is a dynamic process including factors such as fantasies, desires, and behaviors. Self-definition of sexual identity is affected by individual

    Sexual excitement can be seen as an action disposition. In this study sexual arousal was expected to generate sexual action and to increase interest and responsiveness to sexual stimuli. In two experiments, male and female participants were exposed to a neutral or a sexual film. We measured genital and subjective responses to the film, and sexual behavior following the laboratory visit. In Experiment 2, film exposure was followed by a task in which participants rated the sexual arousability of neutral and sexual pictures. Rating time of the sexual pictures served as an index for sexual interest. Responsiveness to the sexual pictures was measured by modulation of spinal tendinous (T) reflexes. Sexual activity, but not sexual desire, was higher for participants in the sexual film condition than for participants in the neutral condition. Sexual interest and responsiveness to still pictures were not higher for participants in the sexual film condition than for those in the neutral film condition. In addition, men who saw the neutral film showed a greater responsiveness to still pictures than men who saw the sexual film. The results support the view of sexual arousal as an emotional state generating action tendencies and actual sexual behavior.

    The successful pharmacological treatment of erectile dysfunction in males has led to increasing interest in the sexual problems of women. Yet in recent years there has been growing consensus regarding the differences between male and female sexuality. William Masters and Virginia Johnson's model of sexual response, revised by Helen Singer Kaplan, has been generally accepted for many decades. This model consists of 4 successive phases: desire, excitement (arousal), orgasm and resolution. Rosemary Basson has suggested a different model, valid especially in long-term relationships. According to Basson, a woman may decide to seek a stimuli necessary to ignite sexual desire, for reasons which are not sexual (such as the need for intimacy or emotional bonding). The desire develops at a latter stage, as a consequence and not as a cause. As the understanding of the sexual response grows, new methods of classification and treatment are being developed. Female sexual dysfunction is common, frequently neglected and has a significant impact on the lives of women. It has a diverse etiology including anatomical, physiological, medical as well as psychological and social factors. The assessment of these disorders incorporates both medical and psychological evaluation. The treatment includes education, improvement of inter-personal communication, behavioral treatment and the solution of medical problems. Different medications are being developed but most have yet to be proven effective. This review presents the female sexual response as it is understood today and the different methods of classification, diagnosis and treatment of female sexual dysfunction.

  17. Circular and linear modeling of female sexual desire and arousal.

    2011-03-01

    There is debate in the scientific literature regarding which model most accurately represents the female sexual response. Traditionally, sex research has been conducted within the framework of the linear sexual response model proposed by Masters and Johnson, modified by Kaplan, then Robinson. Criticism of linear models prompted the development of a composite model of the female sexual response by Basson et al., which included linear and circular pathways. This review aims to systematically assess published studies to determine the extent to which circular and linear models or pathways reflect the female sexual response. Medline, EMBASE, and PsychINFO databases were searched for original data papers and review articles. Inclusion criteria were that articles were published since 1990, in English, and compared linear and circular sexual response models or addressed aspects of these models. Reviews were required to be systematic and include a meta-analysis. Of the 898 studies identified through the initial literature search, 13 original studies and one review met the inclusion criteria. Two studies directly compared models providing limited evidence that most women identify with linear sexual response pathways. However, there is increasing evidence that circular pathways may accurately reflect some aspects of the female sexual response. Further comparative studies are encouraged.

  19. Male sexual harassment alters female social behaviour towards other females.

    2012-04-23

    Male harassment of females to gain mating opportunities is a consequence of an evolutionary conflict of interest between the sexes over reproduction and is common among sexually reproducing species. Male Trinidadian guppies Poecilia reticulata spend a large proportion of their time harassing females for copulations and their presence in female social groups has been shown to disrupt female-female social networks and the propensity for females to develop social recognition based on familiarity. In this study, we investigate the behavioural mechanisms that may lead to this disruption of female sociality. Using two experiments, we test the hypothesis that male presence will directly affect social behaviours expressed by females towards other females in the population. In experiment one, we tested for an effect of male presence on female shoaling behaviour and found that, in the presence of a free-swimming male guppy, females spent shorter amounts of time with other females than when in the presence of a free-swimming female guppy. In experiment two, we tested for an effect of male presence on the incidence of aggressive behaviour among female guppies. When males were present in a shoal, females exhibited increased levels of overall aggression towards other females compared with female only shoals. Our work provides direct evidence that the presence of sexually harassing males alters female-female social behaviour, an effect that we expect will be recurrent across taxonomic groups.

    Objective This study used functional magnetic resonance imaging (fMRI) to contrast the differential brain activation patterns in response to visual stimulation with both male and female erotic nude pictures in male-to-female (MTF) transsexuals who underwent a sex reassignment surgery. Materials and Methods A total of nine healthy MTF transsexuals after a sex reassignment surgery underwent fMRI on a 3.0 Tesla MR Scanner. The brain activation patterns were induced by visual stimulation with both male and female erotic nude pictures. Results The sex hormone levels of the postoperative MTF transsexuals were in the normal range of healthy heterosexual females. The brain areas, which were activated by viewing male nude pictures when compared with viewing female nude pictures, included predominantly the cerebellum, hippocampus, putamen, anterior cingulate gyrus, head of caudate nucleus, amygdala, midbrain, thalamus, insula, and body of caudate nucleus. On the other hand, brain activation induced by viewing female nude pictures was predominantly observed in the hypothalamus and the septal area. Conclusion Our findings suggest that distinct brain activation patterns associated with visual sexual arousal in postoperative MTF transsexuals reflect their sexual orientation to males.

    This study used functional magnetic resonance imaging (fMRI) to contrast the differential brain activation patterns in response to visual stimulation with both male and female erotic nude pictures in male-to-female (MTF) transsexuals who underwent a sex reassignment surgery. A total of nine healthy MTF transsexuals after a sex reassignment surgery underwent fMRI on a 3.0 Tesla MR Scanner. The brain activation patterns were induced by visual stimulation with both male and female erotic nude pictures. The sex hormone levels of the postoperative MTF transsexuals were in the normal range of healthy heterosexual females. The brain areas, which were activated by viewing male nude pictures when compared with viewing female nude pictures, included predominantly the cerebellum, hippocampus, putamen, anterior cingulate gyrus, head of caudate nucleus, amygdala, midbrain, thalamus, insula, and body of caudate nucleus.

  2. The evolution of female sexuality and mate selection in humans.

    Small, M F

    1992-06-01

    Understanding female sexuality and mate choice is central to evolutionary scenarios of human social systems. Studies of female sexuality conducted by sex researchers in the United States since 1938 indicate that human females in general are concerned with their sexual well-being and are capable of sexual response parallel to that of males. Across cultures in general and in western societies in particular, females engage in extramarital affairs regularly, regardless of punishment by males or social disapproval. Families are usually concerned with marriage arrangements only insofar as those arrangements are economically or politically advantageous, but females most often have a voice in arranged marriages. Extended families also concentrate on a couple's future reproduction rather than on sexual exclusivity. Although marriage for females is often compromised by male or family reproductive interests (which may not in fact differ from female interests), females appear to exercise their sexuality with more freedom than has previously been suggested. Notions of human females as pawns in the male reproductive game, or as traders of sex for male services, should be dispelled.

  3. Human sexual response.

    The human sexual response to sexually arousing stimuli is a motivational incentive-based cycle comprising subjective experience and physiologic changes. Clinical and empirical data support a circular model of overlapping phases of variable order. Brain imaging data of sexual arousal identify areas of cerebral activation and inhibition reflecting a complex network of cognitive, motivational, emotional, and autonomic components. Psychologic and biologic factors influence the brain's appraisal and processing of sexual stimuli to allow or disallow subsequent arousal. The sexual and non-sexual outcomes influence motivation to future sexual intimacy. Variability is marked both between individuals and within a person's sexual life, influenced by multiple factors, including stage of life cycle, mental health, and relationship happiness. Neurologic disease can interrupt the cycle at many points: by limiting motivation, reducing ability to attend to and feel sexual stimuli, and accomplishing the movements needed to stimulate and experience intercourse. Impairments to genital congestion, penile erection, and orgasm may also occur. Disease-associated changes to the interpersonal relationship and self-image plus frequently comorbid depression will tend to lessen motivation and temper the brain's appraisal of sexual stimuli, so precluding arousal. Therapy begins by explaining the sexual response cycle, clarifying the points of interruption in the patient's own cycle so as to guide treatment.

  4. Pharmacology of serotonin and female sexual behavior.

    2014-06-01

    In this review, first a historical perspective of serotonin's (5-HT) involvement in female sexual behavior is presented. Then an overview of studies implicating 5-HT is presented. The effect of drugs that increase or decrease CNS levels of 5-HT is reviewed. Evidence is presented that drugs which increase 5-HT have negative effects on female sexual behavior while a decrease in 5-HT is associated with facilitation of sexual behavior. Studies with compounds that act on 5-HT₁, 5-HT₂ or 5-HT₃ receptors are discussed. Most evidence indicates that 5-HT₁A receptor agonists inhibit sexual behavior while 5-HT₂ or 5-HT₃ receptors may exert a positive influence. There is substantial evidence to support a role for 5-HT in the modulation of female consummatory sexual behavior, but studies on the role of 5-HT in other elements of female sexual behavior (e.g. desire, motivation, sexual appetite) are few. Future studies should be directed at determining if these additional components of female sexual behavior are also modulated by 5-HT. Copyright © 2013 Elsevier Inc. All rights reserved.

  5. Integrating Neural Circuits Controlling Female Sexual Behavior

    The hypothalamus is most often associated with innate behaviors such as is hunger, thirst and sex. While the expression of these behaviors important for survival of the individual or the species is nested within the hypothalamus, the desire (i.e., motivation) for them is centered within the mesolimbic reward circuitry. In this review, we will use female sexual behavior as a model to examine the interaction of these circuits. We will examine the evidence for a hypothalamic circuit that regulates consummatory aspects of reproductive behavior, i.e., lordosis behavior, a measure of sexual receptivity that involves estradiol membrane-initiated signaling in the arcuate nucleus (ARH), activating β-endorphin projections to the medial preoptic nucleus (MPN), which in turn modulate ventromedial hypothalamic nucleus (VMH) activity—the common output from the hypothalamus. Estradiol modulates not only a series of neuropeptides, transmitters and receptors but induces dendritic spines that are for estrogenic induction of lordosis behavior. Simultaneously, in the nucleus accumbens of the mesolimbic system, the mating experience produces long term changes in dopamine signaling and structure. Sexual experience sensitizes the response of nucleus accumbens neurons to dopamine signaling through the induction of a long lasting early immediate gene. While estrogen alone increases spines in the ARH, sexual experience increases dendritic spine density in the nucleus accumbens. These two circuits appear to converge onto the medial preoptic area where there is a reciprocal influence of motivational circuits on consummatory behavior and vice versa. While it has not been formally demonstrated in the human, such circuitry is generally highly conserved and thus, understanding the anatomy, neurochemistry and physiology can provide useful insight into the motivation for sexual behavior and other innate behaviors in humans.

    Blanchard's (J Nerv Ment Dis 177:616-623, 1989) theory of autogynephilia suggests that male-to-female transsexuals can be categorized into different types based on their sexuality. Little previous research has compared the sexuality of male-to-female transsexuals to biological females. The present study examined 15 aspects of sexuality among a non-clinical sample of 234 transsexuals and 127 biological females, using either an online or a paper questionnaire. The results showed that, overall, transsexuals tended to place more importance on partner's physical attractiveness and reported higher scores on Blanchard's Core Autogynephilia Scale than biological females. In addition, transsexuals classified as autogynephilic scored significantly higher on Attraction to Feminine Males, Core Autogynephilia, Autogynephilic Interpersonal Fantasy, Fetishism, Preference for Younger Partners, Interest in Uncommitted Sex, Importance of Partner Physical Attractiveness, and Attraction to Transgender Fiction than other transsexuals and biological females. In accordance with Blanchard's theory, autogynephilia measures were positively correlated to Sexual Attraction to Females among transsexuals. In contrast to Blanchard's theory, however, those transsexuals classified as autogynephilic scored higher on average on Sexual Attraction to Males than those classified as non-autogynephilic, and no transsexuals classified as autogynephilic reported asexuality.

    Hormones orchestrate and coordinate human female sexual development, sexuality, and reproduction in relation to three types of phenotypic changes: life history transitions such as puberty and childbirth, responses to contextual factors such as caloric intake and stress, and cyclical patterns such as the ovulatory cycle. Here, we review the endocrinology underlying women's reproductive phenotypes, including sexual orientation and gender identity, mate preferences, competition for mates, sex drive, and maternal behavior. We highlight distinctive aspects of women's sexuality such as the possession of sexual ornaments, relatively cryptic fertile windows, extended sexual behavior across the ovulatory cycle, and a period of midlife reproductive senescence-and we focus on how hormonal mechanisms were shaped by selection to produce adaptive outcomes. We conclude with suggestions for future research to elucidate how hormonal mechanisms subserve women's reproductive phenotypes.

  11. [Female sexual function and chronic disease].

    Female sexual dysfunction (FSD) is a multifactorial set of conditions associated with multiple anatomical, physiological, biological, medical and psychological factors that can have major impact on self-esteem, quality of life, mood and relationships. Studies indicate that FSD is commonly seen in women who report a low level of satisfaction with partner relationship and in women with male partners who have erectile dysfunction. This complexity of FSD is augmented by the presence of chronic disease. Negative sexual effects are widely reported in studies of women with chronic diseases (such as metabolic syndrome, diabetes mellitus, chronic kidney disease, cancer, spinal cord injury, lupus, rheumatic diseases, Parkinson's disease, fibromyalgia and chronic pain) as compared to a general healthy female population. Physical problems, emotional problems and partnership difficulties arising from disease-related stress contribute to less active and less enjoyable sex life. Chronic pain, fatigue, low self-esteem as well as use of medications might reduce sexual function. These effects of chronic diseases on female sexual function still remain largely unstudied. The study by Manor and Zohar published in this issue of Harefuah draws our attention to the sexual dysfunction of women with breast cancer and examines their needs for information regarding their sexual function. In the absence of definite treatment evidence, psychological counseling, improved vaginal lubrication, low dose of hormonal therapy can be used to relieve FSD. Physicians must consider integrating diagnosis of their female patients' sexual needs and dysfunction, especially women with chronic diseases. Patients' education and counseling may contribute to a better quality of life in spite of their chronic disease.

  15. Sexually dimorphic octopaminergic neurons modulate female postmating behaviors in Drosophila.

    Mating elicits profound behavioral and physiological changes in many species that are crucial for reproductive success. After copulation, Drosophila melanogaster females reduce their sexual receptivity and increase egg laying [1, 2]. Transfer of male sex peptide (SP) during copulation mediates these postmating responses [1, 3-6] via SP sensory neurons in the uterus defined by coexpression of the proprioceptive neuronal marker pickpocket (ppk) and the sex-determination genes doublesex (dsx) and fruitless (fru) [7-9]. Although neurons expressing dsx downstream of SP signaling have been shown to regulate postmating behaviors [9], how the female nervous system coordinates the change from pre- to postcopulatory states is unknown. Here, we show a role of the neuromodulator octopamine (OA) in the female postmating response. Lack of OA disrupts postmating responses in mated females, while increase of OA induces postmating responses in virgin females. Using a novel dsx(FLP) allele, we uncovered dsx neuronal elements associated with OA signaling involved in modulation of postmating responses. We identified a small subset of sexually dimorphic OA/dsx(+) neurons (approximately nine cells in females) in the abdominal ganglion. Our results are consistent with a model whereby OA neuronal signaling increases after copulation, which in turn modulates changes in female behavior and physiology in response to reproductive state.

    2010-10-01

    This study examines the role that a history of child sexual abuse played in the diagnosis and treatment of mental disorders in a sample of 321 female offenders incarcerated in a maximum-security prison for women. The results show that a history of child sexual abuse increases the likelihood that an inmate would receive mental health treatment. Psychotropic medication is frequently prescribed in response to adjustment problems associated with childhood sexual abuse. White women who exhibit adjustment problems associated with a history of child sexual abuse are especially likely to be diagnosed as mentally disordered at admission and to be sent to the mental health unit for treatment. In the absence of a diagnosed mental disorder at admission, women who receive psychotropic medication to help them adjust to prison life are likely to be diagnosed with a mental disorder later on.

    Full Text Available This article came from the monographic study “Resilience and Sexual Violence: a study of adolescents victimized by sexual abuse assistance” (MARANHÃO, 2008, in which was investigated the building resilience in victimized adolescents. Resilience is characterized as overcoming adversity, setting up as something procedural, promoted by the interaction of personal and collective protection, in particular context of risk or social vulnerability. We made the trimming about the meanings and feelings of sexual victimization within the family from the perception of adolescents between 12 and 16 years of age that received care in a Specialized Reference Social Assistance in 2010. The research is qualitative, having as theoretical-methodological referential the Historic-Cultural Theory. Data collection was used by semi-structured interview. We realize that the profile of the victims are set up by females, the beginning of sexual abuse occurred between childhood and preadolescence. The profile of perpetrators are men, adults, acting the role of the stepfather, father and uncle. Despite an abject sense, adolescents could not break the cycle of violence. Friends, extended family, and the work of professionals emerged as support for the redefinition of the abusive relationships.

    Sexuality-related constructs, such as sexual arousal, sexual sensation seeking (SSS) and sexual satisfaction, have been related to sexual behaviours that place one at risk of adverse consequences, such as sexually transmissible infections, HIV and unintended pregnancy. The biopsychosocial model posits an array of factors, ranging from social environmental factors to biological and psychological predispositions, that may be associated with these sexuality constructs in adolescents. Female African Americans aged 14-20 years were recruited from reproductive health clinics for an HIV intervention. Baseline survey and follow-up DNA data (n=304) were used to assess biological, psychological and social environmental associations with the sexuality constructs of arousal, SSS and sexual satisfaction. Multivariate linear regression analysis revealed that a higher depressive symptom rating was associated with higher arousability, whereas short serotonin transporter gene allele(s) status was associated with lower arousability. Impulsivity and perceived peer norms supportive of unsafe sexual behaviours were associated with increased SSS, whereas short serotonin transporter gene allele(s) status was associated with lower SSS. Higher social support was associated with higher levels of sexual satisfaction, whereas short serotonin transporter gene allele(s) status was associated with lower satisfaction. The sexuality constructs were also significantly related to the number of sex partners, the frequency of vaginal sex and the number of unprotected vaginal sex acts in the past 6 months. The findings emphasise the importance of understanding biopsychosocial factors, including the role of serotonin as an indicator of natural variations in sexual inclination and behaviours, that influence sexuality constructs, which, in turn, are associated with sexual behaviours, to allow further refinement of sexual health clinical services and programs and promote the development of healthy

    Women's sexual function is a complex and dynamic interplay of variables that involve physical, emotional, and psychosocial states. Sexual dysfunction may occur at any level, and diagnosing such issues begins with careful assessment through a sexual health history. However, discussions about female sexual health and function are often deficient in the primary care setting. This article reviews the published research on female sexual function, sexual dysfunction, and sexual function in pregnancy to gain a better understanding of how these aspects of a woman's life impact the health care services she receives. The evaluation of female sexual function is in need of consistent measurement tools and more dialogue during health care visits. Women's health care practitioners have an opportunity to advance patient satisfaction and overall health by evaluating and communicating with female patients about their sexual function.

    Female sexual behavior is sensitive to stress and diseases. Some studies have shown that status epilepticus (SE) can affect sexual proceptivity and receptivity in female rats and also increases reject responses towards males. However, epidemiologic studies indicate that SE is more frequent in young individuals. Herein, we assessed the effects of SE in infant females on their sexual behavior during adulthood. Thirteen-day-old (P13) rat pups received intraperitoneal injections of lithium chloride (3 mEq/kg). Twenty hours later, at P14, SE was induced by subcutaneous injection of pilocarpine hydrochloride (100 mg/kg s.c.). Control animals were given an equal volume of saline subcutaneously. The animals were weaned at P21 and, later in adulthood, were ovariectomized and hormone-primed with estradiol+progesterone, and their sexual behavior assessed during 4 separate trials of 30 min each with a stud male. Our results indicate that proceptive behaviors (solicitations and hops and darts) were impaired during the first trial, but no alterations were observed for receptivity and attractivity. By trial 3, all SE females displayed normal proceptivity. These results indicate that SE in infancy readily affects proceptivity in a reversible manner. We discuss the role of sexual experience in recovery.

    Full Text Available The etiology of female sexual dysfunction includes psychological, physiological and iatrogenic causes. Physiological and iatrogenic causes are abdominal surgery, menopause, smoking, spinal cord injuries and some antipsychotic, antihypertensive, and antidepressant drugs. When assessing sexual function, sexual function questionnaires, such as the Female Sexual Function Index, and the Sexual Function Questionnaire are used. The prevalence of female sexual dysfunction is 43% and it has been reported to increase depending on menopause and age. Estrogen, estrogen + testosterone and tibolone, PDE5, apomorphine, bupropion and flibanserin are used in the treatment of female sexual dysfunction. Overactive bladder is a disease affecting the quality of life and is characterized by urgency, frequency, nocturia and urge incontinence with especially filling phase of the bladder resulting from loss of detrusor muscle inhibition. The prevalence of overactive bladder in women in the United States has been reported to be 16.9%. Lower urinary tract symptoms and overactive bladder syndrome are not known how to cause female sexual dysfunction. Menopause and partner status were the most important predictors for female sexual dysfunction. It has been reported that overactive bladder syndrome and urinary incontinence provide prediction of development of female sexual dysfunction. Shame, fear of incontinence, and urinary incontinence as well as urge sensation during sexual intercourse in individuals with overactive bladder syndrome have been reported to be the main factors causing female sexual dysfunction. Pathophysiological relationship between the two disorders has not been elucidated and further clinical and experimental studies are needed in this regard.

    2013-01-01

    In sex role reversed species,predominantly females evolve sexually selected traits,such as ornaments and/or weapons.Female ornaments are common and their function well documented in many species,whether sex role reversed or not.However,sexually selected female weapons seem totally absent except for small wing spurs in three jacana species,present in both males and females.This poor female weaponry is in sharp contrast to the situation in species with conventional sex roles:males commonly have evolved sexually selected weapons as well as ornaments.At the same time,females in many taxa have naturally selected weapons,used in competition over resources or in predator defence.Why are sexually selected weapons then so rare,almost absent,in females? Here I briefly review weaponry in females and the function of these weapons,conclude that the near absence of sexually selected weapons begs an explanation,and suggest that costs of sexually selected weapons may exceed costs of ornaments.Females are more constrained when evolving sexually selected traits compared to males,at least compared to those males that do not provide direct benefits,as trait costs reduce a female's fecundity.I suggest that this constraining trade-off between trait and fecundity restricts females to evolve ornaments but rarely weapons.The same may apply to paternally investing males.Whether sexually selected weapons actually are more costly than sexually selected ornaments remains to be investigated.

  9. Sexual and social competition: broadening perspectives by defining female roles.

    Rubenstein, Dustin R

    2012-08-19

    Males figured more prominently than females in Darwin's view of sexual selection. He considered female choice of secondary importance to male-male competition as a mechanism to explain the evolution of male ornaments and armaments. Fisher later demonstrated the importance of female choice in driving male trait evolution, but his ideas were largely ignored for decades. As sexual selection came to embrace the notions of parent-offspring and sexual conflict, and experimental tests of female choice showed promise, females began to feature more prominently in the framework of sexual selection theory. Recent debate over this theory has centred around the role of females, not only over the question of choice, but also over female-female competition. Whereas some have called for expanding the sexual selection framework to encompass all forms of female-female competition, others have called for subsuming sexual selection within a broader framework of social selection, or replacing it altogether. Still others have argued for linking sexual selection more clearly to other evolutionary theories such as kin selection. Rather than simply debating terminology, we must take a broader view of the general processes that lead to trait evolution in both sexes by clearly defining the roles that females play in the process, and by focusing on intra- and inter-sexual interactions in males and females.

    2012-01-01

    We analyzed associations of dissatisfaction with sexual life and desire for change in female medical students. Students enrolled in medical schools in North America between February and July 2008 were invited to participate in an internet based survey of sexual function. The principle outcome measure was a single item question on sexual life satisfaction and desire for change. Women who reported dissatisfaction and desire for change were classified as “sexually bothered”. The survey also assessed ethnodemographic factors, student status, sexual history, and depressive symptoms. Respondents completed the Female Sexual Function Index (FSFI) and the Index of Sex Life (ISL). Descriptive statistics, ANOVA, and multivariable logistic regression were utilized to analyze responses. There were 661 non-virgin female subjects with data adequate for analysis. Whereas 281 (43%) of these met criteria for High Risk of Female Sexual Dysfunction (HRFSD) based on FSFI scoring, just 173 (26%) reported sexual bother. Among women with HRFSD, 126 (45%) reported sexual bother; in women without HRFSD, 362 (95%) were not sexually bothered. Interference in sexual life from tiredness and stress were associated with sexual bother. Progressively better scores on the FSFI-desire, orgasm, and satisfaction domains were significantly associated with lower odds of sexual bother. Few women in this cohort with FSFI score >26.55 reported sexual bother. Women with FSFI less than 26.55 had greater odds of sexual bother but this criterion alone was not pathognomonic for sexual concerns. Issues of sexual desire and orgasm appear to play a more important role than lubrication, arousal, and sexual pain issues in this population. PMID:22971616

    In France, Mariatou Koita, a woman born of Malian parents, endured female genital mutilation as a child at the hands of another Malian immigrant. When the mutilator returned years later to perform genital mutilation on Koita's younger sister, Koita took action that resulted in the first case of female genital mutilation tried in France upon the complaint of a victim. The mutilator was sentenced to 8 years in jail for mutilating 48 young girls in the period 1983-94, and 23 mothers and 3 fathers received prison or suspended prison sentences. Women are struggling against another form of sexual violence in South Africa, where Johannesburg is gaining the reputation as the "rape capital" of the world. Surveys by a nongovernmental organization (NGO) have revealed that a third of 4000 women interviewed were raped in the past year and that 25% of the boys in a sample of 1500 school children considered gang rape a recreational activity. In response, the NGO is creating recommendations to address the problem in schools and to raise the role model profile of men who oppose sexual violence. Also, in Wynberg, Western Cape, a special Sexual Offenses Court has been created to mitigate some of the difficulties rape victims have encountered with the legal system. Global studies indicate that most victims of sexual assaults are adolescent girls.

  12. Representing female desire within a labial framework of sexuality.

    Sexual experiences, rather than being neutral, are specifically male or female. Yet at present no conceptual framework exists for representing female sexual desire. This has resulted in frequent misrepresentations of female sexual experience. To correct this, a labial framework is proposed, not to replace or oppose a phallic framework, but to exist alongside it. The lips of the mouth and those of the genitals provide a felicitous doubling of sexuality and speech to represent female desire and sexual pleasure as labial. Phallic and labial rhythms are organized differently in sexual arousal and desire, since, as Simone de Beauvoir put it, "Man 'gets stiff,' but woman 'gets wet.'" The labial framework therefore represents female psychosexuality more in terms of "wetware" than of "hardware."

    With increasing age many women suffer from lower urinary tract dysfunction (LUTD) and female sexual dysfunction. An increasing body of evidence supports an association between the 2 conditions. Especially women with urodynamically proved detrusor hyperactivity suffer from sexual dysfunction and there is some evidence that in patients with stress incontinence sexual health improves after successful surgery.

    Bass, Tanya M

    Sexuality is inseparable from sexual health and can refer to sex, gender identities, orientation, pleasure, intimacy, expression, and reproduction. While each element of human sexuality is important, all of these components interconnect to make us complete sexual beings. Educators and other human service providers thus require professional preparation to ensure they can meet the needs of their learners, effectively manage programming, and successfully implement strategies that allow individuals to embrace or manage their sexual existence. An inclusive approach to sexual health is best to meet the sexual health needs of all women, while ensuring their agency and control of their own bodies.

  18. Sexual swellings advertise female quality in wild baboons.

    2001-03-08

    The females of many Old World primate species produce prominent and conspicuous swellings of the perineal skin around the time of ovulation. These sexual swellings have been proposed to increase competition among males for females or to increase the likelihood of a female getting fertilized, by signalling either a female's general reproductive status, or the timing of her ovulation. Here we show that sexual swellings in wild baboons reliably advertise a female's reproductive value over her lifetime, in accordance with a theoretical model of honest signalling. Females with larger swellings attained sexual maturity earlier, produced both more offspring and more surviving offspring per year than females with smaller swellings, and had a higher overall proportion of their offspring survive. Male baboons use the size of the sexual swelling to determine their mating effort, fighting more aggressively to consort females with larger swellings, and spending more time grooming these females. Our results document an unusual case of a sexually selected ornament in females, and show how males, by mating selectively on the basis of the size of the sexual swelling, increase their probability of mating with females more likely to produce surviving offspring.

    The clitoris is often considered the female version of the penis and less studied compared to its male counterpart. Nonetheless, it carries the same importance in sexual functioning. While it has more recently been allocated the appreciation it deserves, the clitoris should be examined as a separate and unique entity. To review clitoral anatomy, its role in sexual functioning, the controversies of vaginal eroticism and the female prostate, as well as address potential impacts of pelvic surgery on its function. We examined available evidence (from 1950 until 2015) relating to clitoral anatomy, the clitoral role in sexual functioning, vaginal eroticism, female prostate, female genital mutilation/cutting, and surgical implications for the clitoris. Main outcomes included an historical review of the clitoral anatomy and its role in sexual functioning, the controversies regarding vaginal sources of sexual function, and the impact of both reconstructive and nonmedical procedures on the clitoris. The intricate neurovasculature and multiplanar design of the clitoris contribute to its role in female sexual pleasure. Debate still remains over the exclusive role of the clitoris in orgasmic functioning. Normal sexual function may remain intact, however, after surgical procedures involving the clitoris and surrounding structures. The clitoris is possibly the most critical organ for female sexual health. Its importance is highlighted by the fact that the practice of female genital cutting is often used to attenuate the female sexual response. While its significance may have been overshadowed in reports supporting vaginal eroticism, it remains pivotal to orgasmic functioning of most women. Donna Mazloomdoost and Rachel N. Pauls.

    The female sexual response is complex and influenced by several biological, psychological, and social factors. Testosterone is believed to modulate a woman's sexual response and desire, because low levels are considered a risk factor for impaired sexual function, but previous studies have been inconclusive. To investigate how androgen levels and psychosocial factors are associated with female sexual dysfunction (FSD), including hypoactive sexual desire disorder (HSDD). The cross-sectional study included 428 premenopausal women 19 to 58 years old who completed a questionnaire on psychosocial factors and had blood sampled at days 6 to 10 in their menstrual cycle. Logistic regression models were built to test the association among hormone levels, psychosocial factors, and sexual end points. Five different sexual end points were measured using the Female Sexual Function Index and the Female Sexual Distress Scale: impaired sexual function, sexual distress, FSD, low sexual desire, and HSDD. Serum levels of total and free testosterone, androstenedione, dehydroepiandrosterone sulfate, and androsterone glucuronide were analyzed using mass spectrometry. After adjusting for psychosocial factors, women with low sexual desire had significantly lower mean levels of free testosterone and androstenedione compared with women without low sexual desire. None of the androgens were associated with FSD in general or with HSDD in particular. Relationship duration longer than 2 years and mild depressive symptoms increased the risk of having all the sexual end points, including FSD in general and HSDD in particular in multivariate analyses. In this large cross-sectional study, low sexual desire was significantly associated with levels of free testosterone and androstenedione, but FSD in general and HSDD in particular were not associated with androgen levels. Length of relationship and depression were associated with FSD including HSDD. Wåhlin-Jacobsen S, Kristensen E, Tønnes Pedersen A

  1. Sexual behavior in female western lowland gorillas (Gorilla gorilla gorilla): evidence for sexual competition.

    2009-07-01

    Previous research in gorillas suggests that females engage in post-conception mating as a form of sexual competition designed to improve their own reproductive success. This study focused on sexual behaviors in a newly formed group of western lowland gorillas (Gorilla gorilla gorilla) housed at Zoo Atlanta. All females engaged in mating outside their conceptive periods, although there was individual variation in the frequency of the behavior. An analysis of the presence/absence of sexual behavior found females, regardless of reproductive condition, were more likely to engage in sexual behavior on days when other females were sexually active. On these "co-occurrence" days, females were significantly more likely to solicit the silverback, but copulations did not differ from expectation. The results find further evidence for sexual competition among female gorillas and suggest that this may occur throughout their reproductive cycle rather than only during pregnancy.

  2. Embryology and anatomy of the vulva: the female orgasm and women's sexual health.

    Sexual health is vital to overall well-being. Orgasm is a normal psycho-physiological function of human beings and every woman has the right to feel sexual pleasure. The anatomy of the vulva and of the female erectile organs (trigger of orgasm) is described in human anatomy textbooks. Female sexual physiology was first described in Dickinson's textbook in 1949 and subsequently by Masters and Johnson in 1966. During women's sexual response, changes occur in the congestive structures that are essential to the understanding of women's sexual response and specifically of their orgasm. Female and male external genital organs arise from the same embryologic structures, i.e. phallus, urogenital folds, urogenital sinus and labioscrotal swellings. The vulva is formed by the labia majora and vestibule, with its erectile apparatus: clitoris (glans, body, crura), labia minora, vestibular bulbs and corpus spongiosum. Grafenberg, in 1950, discovered no "G-spot" and did not report an orgasm of the intraurethral glands. The hypothetical area named "G-spot" should not be defined with Grafenberg's name. The female orgasm should be a normal phase of the sexual response cycle, which is possible to achieve by all healthy women with effective sexual stimulation. Knowledge of the embryology, anatomy and physiology of the female erectile organs are important in the field of women's sexual health.

  3. A preference for a sexual signal keeps females safe.

    Directory of Open Access Journals (Sweden)

    Tae Won Kim

    Full Text Available Predation is generally thought to constrain sexual selection by female choice and limit the evolution of conspicuous sexual signals. Under high predation risk, females usually become less choosy, because they reduce their exposure to their predators by reducing the extent of their mate searching. However, predation need not weaken sexual selection if, under high predation risk, females exhibit stronger preferences for males that use conspicuous signals that help females avoid their predators. We tested this prediction in the fiddler crab Uca terpsichores by increasing females' perceived predation risk from crab-eating birds and measuring the attractiveness of a courtship signal that females use to find mates. The sexual signal is an arching mound of sand that males build at the openings of their burrows to which they attract females for mating. We found that the greater the risk, the more attractive were males with those structures. The benefits of mate preferences for sexual signals are usually thought to be linked to males' reproductive contributions to females or their young. Our study provides the first evidence that a female preference for a sexual signal can yield direct survival benefits by keeping females safe as they search for mates.

    This article reviews and critiques the DSM-IV-TR diagnostic criteria for Female Sexual Arousal Disorder (FSAD). An overview of how the diagnostic criteria for FSAD have evolved over previous editions of the DSM is presented and research on prevalence and etiology of FSAD is briefly reviewed. Problems with the essential feature of the DSM-IV-TR diagnosis-"an inability to attain, or to maintain...an adequate lubrication-swelling response of sexual excitement"-are identified. The significant overlap between "arousal" and "desire" disorders is highlighted. Finally, specific recommendations for revision of the criteria for DSM-V are made, including use of a polythetic approach to the diagnosis and the addition of duration and severity criteria.

    2014-02-01

    The purpose of the present study was to examine the relationship between college women's sexual victimization experiences, health risk behaviors, and sexual functioning. A sample of 309 college women at a mid-sized Midwestern university completed measures assessing sexual victimization, sexual risk taking, substance use behaviors, sexual desire, sexual functioning, prior sexual experiences, and social desirability. Severity of sexual victimization was measured using a multi-item, behaviorally specific, gender-neutral measure, which was divided into four categories based on severity (none, sexual contact, sexual coercion, rape). Within the sample, 72.8% (n = 225) of women reported at least one experience of sexual victimization since age 16. Results from MANCOVAs and a multinomial logistic regression, controlling for social desirability and prior sexual experience, revealed that sexual victimization among female students was related to increased drug use, problematic drinking behaviors, sexual risk taking, sexual dysfunction, and dyadic sexual desire. In addition, findings indicated that women exposed to more severe forms of sexual victimization (i.e., rape) were most likely to report these risk-taking behaviors and sexual functioning issues. Implications for sexual assault risk reduction programming and treatment are discussed.

  6. Sexual desire, not hypersexuality, is related to neurophysiological responses elicited by sexual images.

    Modulation of sexual desires is, in some cases, necessary to avoid inappropriate or illegal sexual behavior (downregulation of sexual desire) or to engage with a romantic partner (upregulation of sexual desire). Some have suggested that those who have difficulty downregulating their sexual desires be diagnosed as having a sexual 'addiction'. This diagnosis is thought to be associated with sexual urges that feel out of control, high-frequency sexual behavior, consequences due to those behaviors, and poor ability to reduce those behaviors. However, such symptoms also may be better understood as a non-pathological variation of high sexual desire. Hypersexuals are thought to be relatively sexual reward sensitized, but also to have high exposure to visual sexual stimuli. Thus, the direction of neural responsivity to sexual stimuli expected was unclear. If these individuals exhibit habituation, their P300 amplitude to sexual stimuli should be diminished; if they merely have high sexual desire, their P300 amplitude to sexual stimuli should be increased. Neural responsivity to sexual stimuli in a sample of hypersexuals could differentiate these two competing explanations of symptoms. Fifty-two (13 female) individuals who self-identified as having problems regulating their viewing of visual sexual stimuli viewed emotional (pleasant sexual, pleasant-non-sexual, neutral, and unpleasant) photographs while electroencephalography was collected. Larger P300 amplitude differences to pleasant sexual stimuli, relative to neutral stimuli, was negatively related to measures of sexual desire, but not related to measures of hypersexuality. Implications for understanding hypersexuality as high desire, rather than disordered, are discussed.

    Sexual assault is a common social disorder among students in our tertiary institutions. This study ascertains the extent and effect of sexual assault among Nigerian students. Two hundred and Sixty Eight structured questionnaires were distributed to randomly selected students in 4 tertiary institutions, information on socio demography, sexual history and consequences of their exposure were obtained for analysis and interpretation. Thirty seven (13.8%) of the respondents were sexually assaulted as a student and 19 (7.1%) were assaulted by their lecturers and fellow students, Younger age at coitarche, history of forced coitarche, marriage, coitarche with relations and unknown persons, significantly influenced subsequent risks of sexual assault. Improve security, moral behaviours enforcing dress code and stiffer penalties were suggested ways to prevent sexual assault among the students. Sexual assault is still a common finding in our institutions; effort should be made by all stake holders to prevent this social embarrassment.

    The trajectory of an animal's growth in early development has been shown to have long-term effects on a range of life-history traits. Although it is known that individual differences in behaviour may also be related to certain life-history traits, the linkage between early growth or development and individual variation in behaviour has received little attention. We used brief temperature manipulations, independent of food availability, to stimulate compensatory growth in juvenile three-spined sticklebacks Gasterosteus aculeatus. Here, we examine how these manipulated growth trajectories affected the sexual responsiveness of the male fish at the time of sexual maturation, explore associations between reproductive behaviour and investment and lifespan and test whether the perceived time stress (until the onset of the breeding season) influenced such trade-offs. We found a negative impact of growth rate on sexual responsiveness: fish induced (by temperature manipulation) to grow slowest prior to the breeding season were consistently quickest to respond to the presence of a gravid female. This speed of sexual responsiveness was also positively correlated with the rate of development of sexual ornaments and time taken to build a nest. However, after controlling for effects of growth rate, those males that had the greatest sexual responsiveness to females had the shortest lifespan. Moreover, the time available to compensate in size before the onset of the breeding season (time stress) affected the magnitude of these effects. Our results demonstrate that developmental perturbations in early life can influence mating behaviour, with long-term effects on longevity.

    2005-01-01

    This study was designed to assess potential differences between sexually functional and dysfunctional women in dopamine (DA) and norepinephrine (NE) responses to erotic stimuli. Blood levels of homovanillic acid (HVA; the major metabolite of DA) and NE were taken during the showing of a nonsexual and a sexual film from 9 women with female sexual arousal disorder and hypoactive sexual desire disorder and from 13 sexually functional women. We assessed sexual arousal subjectively using a self-report scale and physiologically using a vaginal photoplethysmograph. HVA levels significantly decreased in sexually functional and dysfunctional women during the erotic versus during the neutral film. NE levels were not significantly different for either group of women during the neutral and erotic films. Sexually dysfunctional women had significantly higher levels of NE during both the neutral and erotic films compared with functional women. Subjective or physiological arousal differences between neutral and erotic films were not significantly different between functional and dysfunctional women.

  14. Female tail wagging enhances sexual performance in male goats.

    Science.gov (United States)

    Haulenbeek, Andrea M; Katz, Larry S

    2011-08-01

    Preference testing has shown that sexually experienced male goats choose females that are tail wagging, a behavior that may function as both attractivity and proceptivity, over those that are not. We hypothesized that exposure to females expressing high rates of tail wagging would arouse males, increasing sexual performance. Tail wagging rate could be manipulated because we have shown previously that flutamide treatment increases the frequency of tail wagging in estrous goats. Sexually experienced males observed different stimuli for 10 min before a 20 min sexual performance test (SPT). The stimuli were an empty pen (MT), or groups of three females that were all estrous (E), non-estrous (NE), estrous+flutamide (E(F)) or non-estrous+flutamide (NE(F)). During the stimulus observation period, tail wagging was recorded. During SPT, frequencies and latencies of sexual behaviors were recorded. E(F) females displayed the most tail wagging. Viewing E(F) females before SPT increased the number of ejaculations attained by males and decreased the latencies to first and second ejaculation, as well as the inter-ejaculatory interval. Viewing estrous females (E and E(F)) before SPT decreased the latency to first mount, as compared to non-estrous females (NE and NE(F)). We conclude that male goats are sexually aroused by tail wagging. This study and previous work demonstrate that tail wagging functions as both attractivity and proceptivity in goats.

    The aim of this study was to investigate the effects of multiple sclerosis (MS) on female sexuality. Present study included 142 females (70 MS patients, 72 healthy controls). MS patients were evaluated by Expanded Disability Status Scale (EDSS) for functional status, by Beck Depression Inventory (BDI) for severity of depression, by Visual Analog Scale (VAS) for severity of pain, and by Female Sexual Function Inventory (FSFI) for sexual function. FSFI, BDI, EDSS, and VAS were the main outcome measures. The number of weekly sexual intercourse, total FSFI, and FSFI subscale scores were lower in MS women compared with controls. FSFI total and FSFI subscale scores were statistically significantly lower in MS women with BDI score ≥ 17 compared with those with BDI score Sexual functions are negatively affected in MS women. Sexual functions in MS women seem to be associated with enhanced disability, pain, duration of the disease, and degree of concomitant depression. Therefore, women with MS should also be evaluated in terms of sexual function during routine follow-ups. © 2013 International Society for Sexual Medicine.

    We undertook to study possible determinants of female sexual dysfunction (FSD) in a large cohort of female medical students from German-speaking countries. We conducted an online questionnaire-based anonymous survey in a cohort of >2600 female medical students enrolled at German-speaking universities. The questionnaire comprised the Female Sexual Function Index (FSFI) plus additional questions regarding contraception, sexual activity, age, height, weight, lifestyle, activity at work, sexuality and emotional interaction with a steady partner, pregnancy history and plans, health problems, and self-acceptance. Data analysis employed descriptive statistics, univariate and multivariate analyses, and standard nonparametric tests. Of the 2612 respondents aged ≤30 years included in the analysis (mean age [standard deviation], 23.5 [2.5] years), 38.7% of the overall cohort and 33.5% of the sexually active subcohort (91.8% of all students) were at risk for FSD (FSFI score speaking female medical students are at risk for FSD. Contraception, smoking, alcohol, steady relationship, physical fitness, and self-acceptance are significantly associated with the FSFI total score. Being in a steady relationship, better physical fitness, higher activity at work, and subjectively positive self-acceptance, in particular, are associated with higher FSFI total scores, that is, with less risk for sexual dysfunction.

    Full Text Available Background: Female sexual dysfunction (FSD in Indian women is often overlooked due to cultural beliefs and considered as social taboos. Sexuality is an important and integral part of life. There are many causes of sexual dysfunction, but the prevalence of FSD in endometriotic patients is still underdiagnosed. Materials and Methods: Study design - Cross-sectional observational study conducted at tertiary care center, from June 2015 to March 2016. Sample size - Fifty-one patients in reproductive age group (18-47 years who were diagnosed with endometriosis on diagnostic laparoscopy were included. Methods - FSD was assessed with a detailed 19-item female sexual function index questionnaire. All six domains of sexual dysfunction, i.e., desire, arousal, lubrication, orgasm, satisfaction, and pain were studied. Exclusion - Patients with other gynecological, medical or surgical history were excluded. Results: Out of 51 patients with endometriosis, 47.06% of patients had sexual dysfunction. With the increase in staging of endometriosis, sexual dysfunction prevalence is also rising. FSD was 100% in patients with severe endometriosis as compared to 33.33% in minimal endometriosis. Conclusion: Every individual deserves good sexual life. The sexual dysfunction associated with endometriosis should also be taken into consideration while managing these patients.

    Provoked vestibulodynia (PVD) is a recurrent idiopathic vulvo-vaginal pain associated with negative sexual and psychological consequences. Facilitative partner responses to pain are currently receiving empirical attention because they are positively associated with women's sexual outcomes. However, the mechanisms through which facilitative responses to pain are associated with these outcomes have not been examined. One potential mechanism is sexual assertiveness, which has been found to be associated with better sexual function and satisfaction in women with PVD. The present study examined whether women's sexual assertiveness mediated the association between women's perception of facilitative partner responses and women's sexual function and satisfaction. Women (N = 140) with PVD symptomatology completed self-reported questionnaires evaluating their perception of their partners' facilitative responses, and their own sexual assertiveness, sexual function, and sexual satisfaction. Dependent measures were sexual function measured by the Female Sexual Function Index and sexual satisfaction assessed by the Global Measure of Sexual Satisfaction Scale. Results indicated that women's higher sexual assertiveness mediated the association between their greater perceived facilitative partner responses and their improved sexual function and satisfaction. Findings suggest a potential mechanism through which partner responses may be associated with women's sexual outcomes.

    Full Text Available Female sexual dysfunction (FSD defines as any disorder in the process of sexual contact including 6 main domains, desire, arousal, lubrication, orgasm, orgasm satisfaction and pain. This study was conducted to evaluate prevalence of sexual dysfunction disorder in women with migraine headache and also find the associated factors related to migraine characteristics.A total of 69 eligible woman patients fulfilling criteria for migraine participated in this study. The Female Sexual Function Index (FSFI, a multi-dimensional self-report implement for appraisal of Female Sexual Function during the past month were utilized in this study. The information related to migraine including frequency, duration of headache attack, severity of headache according to visual analog scale (VAS score and headache impact test (HIT score were obtained using a self-administrated questionnaire.About 68.4% of patients had an FSFI score < 28. In domains of desire 73.7%, arousal 64.9%, lubrication 21.1%, orgasm 33.3%, satisfaction 17.5%, and pain 40.4% of patients reported some degree of dysfunction. Among variables related to migraine characteristics, only a significant association between frequency and sexual dysfunction were recorded (P < 0.05.FSD is prevalent among migraine patients. The frequency of a migraine attack is associated with FSD. Serotonin mechanisms such as 5HT2, 5HT3 agonist have been hypothesized as a shared etiology for migraine and sexual dysfunction.

    Although health surveys on sexual issues during incarceration have shown that women report having engaged in sexual activities while in prison, studies on sexual functioning in female inmates have been largely dismissed. This study aimed to assess sexual functioning among incarcerated women and determine the psychometric and sociodemographic features that are possibly related to the risk of sexual dysfunction. This was a cross-sectional study conducted inside a penitentiary for women in São Paulo, Brazil. From June 2006 to June 2010, 315 inmates convicted of robbery or homicide were recruited. High risk of female sexual dysfunction (HRFSD) was measured using the Female Sexual Function Index and participants were also evaluated for alcohol and drug misuse, impulsiveness, depressive symptoms, and psychosocial features. Descriptive statistics and multivariate logistic regression were utilized to analyze the data. Among the participants, 253 (80.32 %) met the criteria for HRFSD. Older age, total time of imprisonment, and depressive symptoms were related to a higher risk, while the status of being married, being Black, having sexual relations with other inmates, and receiving conjugal visits were associated with a lower risk. As only 110 (34.92 %) inmates admitted to having sexual relationships inside prison, we evaluated this sub-sample separately. For this sub-sample, 61 (55.45 %) women met the criteria for HRFSD and the main factors associated with this risk were total time of imprisonment and depressive symptoms. Incarcerated women are uniquely vulnerable because they often have histories of deprivation and violence stemming from multiple sources and experience considerable psychological symptoms as a consequence of imprisonment. With the affected population rarely receiving psychosocial management for sexual dysfunction, service delivery efforts should be intensified to target this high-risk population.

  7. Possible evolutionary origins of human female sexual fluidity.

    2016-05-16

    I propose an evolutionary theory of human female sexual fluidity and argue that women may have been evolutionarily designed to be sexually fluid in order to allow them to have sex with their cowives in polygynous marriage and thus reduce conflict and tension inherent in such marriage. In addition to providing an extensive definition and operationalization of the concept of sexual fluidity and specifying its ultimate function for women, the proposed theory can potentially solve several theoretical and empirical puzzles in evolutionary psychology and sex research. Analyses of the National Longitudinal Study of Adolescent Health (Add Health) confirm the theory's predictions that: (i) women (but not men) who experience increased levels of sexual fluidity have a larger number of children (suggesting that female sexual fluidity, if heritable, may be evolutionarily selected); (ii) women (but not men) who experience marriage or parenthood early in adult life subsequently experience increased levels of sexual fluidity; and (iii) sexual fluidity is significantly positively correlated with known markers of unrestricted sexual orientation among women whereas it is significantly negatively correlated with such markers among men.

    Full Text Available Adaptive mate choice by females is an important component of sexual selection in many species. The evolutionary consequences of male mate preferences, however, have received relatively little study, especially in the context of sexual conflict, where males often harm their mates. Here, we describe a new and counterintuitive cost of sexual selection in species with both male mate preference and sexual conflict via antagonistic male persistence: male mate choice for high-fecundity females leads to a diminished rate of adaptive evolution by reducing the advantage to females of expressing beneficial genetic variation. We then use a Drosophila melanogaster model system to experimentally test the key prediction of this theoretical cost: that antagonistic male persistence is directed toward, and harms, intrinsically higher-fitness females more than it does intrinsically lower-fitness females. This asymmetry in male persistence causes the tails of the population's fitness distribution to regress towards the mean, thereby reducing the efficacy of natural selection. We conclude that adaptive male mate choice can lead to an important, yet unappreciated, cost of sex and sexual selection.

    Prospectively track teen childbirths in maltreated and nonmaltreated females and test the hypothesis that child maltreatment is an independent predictor of subsequent teen childbirth over and above demographic characteristics and other risk factors. Nulliparous adolescent females (N = 435) aged 14 to 17 years were assessed annually through age 19 years. Maltreated females were referred by Child Protective Services agencies for having experienced substantiated sexual abuse, physical abuse, or neglect within the preceding 12 months. Comparison females were matched on race, family income, age and family constellation. Teen childbirth was assessed via self-report during annual interviews. Births were confirmed using hospital delivery records. Seventy participants gave birth during the study, 54 in the maltreated group and 16 in the comparison group. Maltreated females were twice as likely to experience teen childbirth after controlling for demographic confounds and known risk factors (odds ratio = 2.17, P = 0.01). Birth rates were highest for sexually abused and neglected females. Sexual abuse and neglect were both independent predictors of teen childbirth after controlling for demographic confounds, other risk factors and alternative forms of maltreatment occurring earlier in development. Results provide evidence that sexual abuse and neglect are unique predictors of subsequent teen childbirth. Partnerships between protective service providers and teen childbirth prevention strategists hold the best promise for further reducing the US teen birth rate. Additional research illuminating the pathways to teen childbirth for differing forms of maltreatment is needed so that tailored interventions can be realized.

    Background. Knowledge about female sexual problems after pre- or postoperative (chemo-)radiotherapy and radical resection of rectal cancer is limited. The aim of this study was to compare self-rated sexual functioning in women treated with or without radiotherapy (RT+ vs. RT?), at least two years after surgery for rectal cancer. Methods and materials. Female patients diagnosed from 1993 to 2003 were identified from a national database, the Norwegian Rectal Cancer Registry. Eligible patients were without recurrence or metastases at the time of the study. The Sexual function and Vaginal Changes Questionnaire (SVQ) was used to measure sexual functioning. Results. Questionnaires were returned from 172 of 332 invited and eligible women (52%). The mean age was 65 years (range 42-79) and the time since surgery for rectal cancer was 4.5 years (range 2.6-12.4). Sexual interest was not significantly impaired in RT+ (n=62) compared to RT? (n=110) women. RT+ women reported more vaginal problems in terms of vaginal dryness (50% vs. 24%), dyspareunia (35% vs. 11%) and reduced vaginal dimension (35% vs. 6%) compared with RT? patients; however, they did not have significantly more worries about their sex life. Conclusion. An increased risk of dyspareunia and vaginal dryness was observed in women following surgery combined with (chemo-)radiotherapy compared with women treated with surgery alone. Further research is required to determine the effect of adjuvant therapy on female sexual function

    Hyperthyroidism is a common hormonal disorder in women that may cause female sexual dysfunction (FSD). To assess sexual function in women with hyperthyroidism. A total of 40 women with clinical hyperthyroidism and 40 age-matched voluntary healthy women controls were included in the study. All the subjects were evaluated with a detailed medical and sexual history, including a Female Sexual Function Index (FSFI) questionnaire for sexual status and the Beck Depression Inventory (BDI) for psychiatric assessment. The levels of serum thyroid-stimulating hormone (TSH), thyroid hormones, sex hormone binding globulin (SHBG), total testosterone (tT), free testosterone (fT), prolactin, estradiol, follicle-stimulating hormone, and luteinizing hormone were measured. The mean total FSFI scores were 24.2 ± 9.96 in the hyperthyroidic group and 29 ± 10.4 in the control group (P hyperthyroidism. The mean BDI score for hyperthyroidic patients was significantly greater than the score for the control group (P hyperthyroidic group was found to be significantly higher than the level in the controls (P hyperthyroidic group was lower than in the control group (P hyperthyroidism had sexual dysfunction. Increased depressive symptoms, increased SHBG level, and decreased fT levels were all found to be associated with FSD in clinical hyperthyroidism. © 2011 International Society for Sexual Medicine.

    Sexuality-related constructs such as sexual arousal, sexual sensation seeking (SSS) and sexual satisfaction have been related to sexual behaviors that place one at risk for adverse consequences such as sexually transmitted infections (STIs), HIV, and unintended pregnancy. The biopsychosocial model posits an array of factors, ranging from social environmental factors, biological, and psychological predispositions that may be associated with these sexuality constructs in adolescent samples. African-American females aged 14-20 were recruited from reproductive health clinics for an HIV intervention. Baseline survey and follow-up DNA data (N=304) was used to assess biological, psychological and social environmental associations with the sexuality constructs of arousal, SSS, and sexual satisfaction. In multivariable linear regressions, a higher depressive symptom rating was associated with higher arousability while short serotonin allele(s) status was associated with lower arousability. Impulsivity and perceived peer norms supportive of unsafe sexual behaviors were associated with increased SSS, and short serotonin allele(s) status was associated with lower SSS. Higher social support was also associated with higher levels of sexual satisfaction while short serotonin allele(s) status was associated with lower satisfaction. The sexuality constructs were also significantly related to number of sex partners, frequency of vaginal sex, and number of unprotected vaginal sex acts in the past six months. These findings emphasize the importance of understanding biopsychosocial factors, including the role of serotonin as an indicator of natural variations in sexual inclination and behaviors, that influence sexuality constructs, which in turn are associated with sexual behaviors, to allow further refinement of sexual health clinical services and programs and promote the development of healthy sexuality.

    This paper aims to analyze the way in which the media reports of sex offences tend to reinforce traditional sexual scripts and gender identities. Compared to investigations into male sex offenders, female sex offending is relatively underresearched, undertheorized, and misunderstood (Hayes and Carpenter, 2013). We argue that the media’s reinforcement of traditional scripts has hindered the development of awareness of sex offending by women, depicting them as aberrations, that is, as “female p...

    This study examined the interactive effects of injunctive norm exposure and hostile and benevolent sexist attitudes on men's sexually aggressive responses during a behavioral analogue paradigm in which they interacted online with a bogus female partner. Heterosexual adult men (n = 201), recruited from an online sample, read fictional information regarding other men's approval of misogynistic, paternalistic, or egalitarian treatment of women, or non-gender-relevant control information. Through a media preference survey, men then learned that their female partner disliked sexual content in films, after which they had an opportunity to send her up to 120 sec' worth of either a sexually explicit or nonsexual film clip. Validating the online sexual aggression paradigm, men with a 1-year history of sexual assault exhibited more sexually aggressive responding during the film selection paradigm. Moreover, exposure to injunctive norm information produced a boomerang effect, such that men high in hostile sexist attitudes showed an increase in sexual aggression when confronted with paternalism and gender equality norms. Conversely, exposure to paternalism and gender equality norms suppressed the otherwise protective function of high benevolent sexism in reducing men's sexually aggressive tendencies. The implications of these results for social norms interventions are discussed.

    We carried out a rapid assessment among the female regular sex partners of drug users/injecting drug users recruited from Bangladesh, Bhutan, India, Nepal and Sri Lanka with the objective of designing appropriate responses targeting them. We examined the correlates of condom use among them. Data was collected from 4612 female regular sex partners recruited by different NGO partners spread across the five countries in the region. We carried out univariate and multivariate logistic regression analysis to determine variables associated with condom use during their last sexual intercourse. Of the total sample, 22% admitted to using drugs ever in their life and 21% reported condom use during the last sexual act. A fourth of the participants have not heard of HIV/AIDS and only 17% have been tested for HIV. In a multivariate model, women engaged in sex work, from Nepal, used drugs before last sexual intercourse, heard of HIV/AIDS, ever used drugs and approached by someone with information on HIV were likely to have used condoms during the last sexual intercourse about twice or more: (AOR=4, 95% CI: 3, 5.3; AOR=3.4, 95% CI: 2.4, 4.9; AOR=2.5, 95% CI: 1.9, 3.3; AOR=2.1, 95% CI: 1.5, 3; AOR=2, 95% CI: 1.5, 2.6; AOR=1.7, 95% CI: 1.4, 2 respectively). Condom use was negatively associated with women with a single sex partner (AOR=0.6, 95% CI: 0.5, 0.7). Condom use is low among the female regular sex partners and is primarily associated with women exhibiting risky practices. Apart from sustaining and expanding HIV prevention programmes that aim to increase the HIV/AIDS related knowledge and scale-up HIV testing among the drug users and their regular sex partners, there is an urgent need to reach out to the women in stable marital relationship with drug users. This study has demonstrated that it is feasible to access this population and the priority is to design and implement individual, couple and group level interventions that ensure consistent condom use with their primary

    Full Text Available Introduction: The patients with type 2 diabetes (T2D suffer from the malfunctions of the sexual behaviors, and several mechanisms have been proposed to describe these disorders. The innate immunity may be involved in the malfunctions of T2D patients. Melanoma differentiation-associated protein 5 (MDA5 and retinoic acid (RA-inducible gene 1 (RIG-1, as the innate immunity receptors, are the responsible molecules for the activation of some intracellular signaling pathways and the induction of inflammation. Thus, this study aimed to examine the molecules which may participate in the induction/stimulation of sexual malfunctions in the female T2D patients. Methods: Sexual functions were evaluated in 41 female T2D patients using the Female Sexual Function Index (FSFI questionnaire. Real-time polymerase chain reaction (PCR technique was used to quantify MDA5 and RIG-1 mRNA levels. Results: Results showed that increased RIG-1 mRNA levels were significantly associated with the bad orgasm in the female T2D patients compared to the female patients with good orgasm. Expression of RIG-1 and MDA5 levels were not associated with other sexual functions’ criteria. Conclusion: The findings of this study demonstrated that bad orgasm is associated with the increased RIG-1 expression. Consequently, the correlation between inflammation and bad orgasm in a RIG-1 dependent manner is suggested.

    Female ornamentation has long been overlooked because of the greater prevalence of elaborate displays in males. However, the circumstances under which females would benefit from honestly signalling their quality are limited. Females are not expected to invest in ornamentation unless the fitness benefits of the ornament exceed those derived from investing the resources directly into offspring. It has been proposed that when females gain direct benefits from mating, females may instead be selected for ornamentation that deceives males about their reproductive state. In the empidid dance flies, males frequently provide nuptial gifts and it is usually only the female that is ornamented. Female traits in empidids, such as abdominal sacs and enlarged pinnate leg scales, have been proposed to 'deceive' males into matings by disguising egg maturity. We quantified sexual selection in the dance fly Rhamphomyia tarsata and found escalating, quadratic selection on pinnate scales and that pinnate scales honestly reflect female fecundity. Mated females had a larger total number and more mature eggs than unmated females, highlighting a potential benefit rather than a cost of male mate choice. We also show correlational selection on female pinnate scales and fecundity. Correlational selection, equivalent investment patterns or increased nutrition from nuptial gifts may all maintain honesty in female ornamentation.

  8. Darcin: a male pheromone that stimulates female memory and sexual attraction to an individual male's odour

    2010-06-01

    Full Text Available Abstract Background Among invertebrates, specific pheromones elicit inherent (fixed behavioural responses to coordinate social behaviours such as sexual recognition and attraction. By contrast, the much more complex social odours of mammals provide a broad range of information about the individual owner and stimulate individual-specific responses that are modulated by learning. How do mammals use such odours to coordinate important social interactions such as sexual attraction while allowing for individual-specific choice? We hypothesized that male mouse urine contains a specific pheromonal component that invokes inherent sexual attraction to the scent and which also stimulates female memory and conditions sexual attraction to the airborne odours of an individual scent owner associated with this pheromone. Results Using wild-stock house mice to ensure natural responses that generalize across individual genomes, we identify a single atypical male-specific major urinary protein (MUP of mass 18893Da that invokes a female's inherent sexual attraction to male compared to female urinary scent. Attraction to this protein pheromone, which we named darcin, was as strong as the attraction to intact male urine. Importantly, contact with darcin also stimulated a strong learned attraction to the associated airborne urinary odour of an individual male, such that, subsequently, females were attracted to the airborne scent of that specific individual but not to that of other males. Conclusions This involatile protein is a mammalian male sex pheromone that stimulates a flexible response to individual-specific odours through associative learning and memory, allowing female sexual attraction to be inherent but selective towards particular males. This 'darcin effect' offers a new system to investigate the neural basis of individual-specific memories in the brain and give new insights into the regulation of behaviour in complex social mammals.

    Full Text Available Introduction: The female condom is the only evidence-based AIDS prevention technology that has been designed for the female body; yet, most women do not have access to it. This is remarkable since women constitute the majority of all HIV-positive people living in sub-Saharan Africa, and gender inequality is seen as a driving force of the AIDS epidemic. In this study, we analyze how major actors in the AIDS prevention field frame the AIDS problem, in particular the female condom in comparison to other prevention technologies, in their discourse and policy formulations. Our aim is to gain insight into the discursive power mechanisms that underlie the thinking about AIDS prevention and women's sexual agency. Methods: We analyze the AIDS policies of 16 agencies that constitute the most influential actors in the global response to AIDS. Our study unravels the discursive power of these global AIDS policy actors, when promoting and making choices between AIDS prevention technologies. We conducted both a quantitative and qualitative analysis of how the global AIDS epidemic is being addressed by them, in framing the AIDS problem, labelling of different categories of people for targeting AIDS prevention programmes and in gender marking of AIDS prevention technologies. Results: We found that global AIDS policy actors frame the AIDS problem predominantly in the context of gender and reproductive health, rather than that of sexuality and sexual rights. Men's sexual agency is treated differently from women's sexual agency. An example of such differentiation and of gender marking is shown by contrasting the framing and labelling of male circumcision as an intervention aimed at the prevention of HIV with that of the female condom. Conclusions: The gender-stereotyped global AIDS policy discourse negates women's agency in sexuality and their sexual rights. This could be an important factor in limiting the scale-up of female condom programmes and hampering

    Many studies have shown the importance of colorful ornamentation in mate choosiness or intrasexual conflict. However, research on color ornaments has focused mainly on birds, lizards or fish, but remains practically unknown in other animal groups such as turtles. In addition, female ornaments and their relation with sexual selection also remain almost unknown. Here, we measured the coloration of the shell and the limb stripes of male and female Spanish terrapins Mauremys leprosa and explored the existence of sexual dichromatism and the relation of color characteristics with body size and health state estimated from the immune response to the injection of an antigen (phytohaemagglutinin test). Our results showed that shell coloration, which could be constrained by natural selection to be cryptic, changed with body size, but did not differ between sexes. In contrast, females had brighter and less ultraviolet-saturated and more orange-saturated limb stripes than males. In females, interindividual variation in limb stripe coloration was related with body size and immune response suggesting that this coloration may inform honestly about multiple traits that could be important in sexual selection. In contrast, coloration of limb stripes of males was duller than in females, and was not related with any trait suggesting that coloration is not important in sexual selection for males.

    We studied the contribution of the main olfactory system to mate recognition and sexual behavior in female mice. Female mice received an intranasal irrigation of either a zinc sulfate (ZnSO4) solution to destroy the main olfactory epithelium (MOE) or saline (SAL) to serve as control. ZnSO4-treated female mice were no longer able to reliably distinguish between volatile as well as nonvolatile odors from an intact versus a castrated male. Furthermore, sexual behavior in mating tests with a sexually experienced male was significantly reduced in ZnSO4-treated female mice. Vomeronasal function did not seem to be affected by ZnSO4 treatment: nasal application of male urine induced similar levels of Fos protein in the mitral and granule cells of the accessory olfactory bulb (AOB) of ZnSO4 as well as SAL-treated female mice. Likewise, soybean agglutinin staining, which stains the axons of vomeronasal neurons projecting to the glomerular layer of the AOB was similar in ZnSO4-treated female mice compared to SAL-treated female mice. By contrast, a significant reduction of Fos in the main olfactory bulb was observed in ZnSO4-treated females in comparison to SAL-treated animals, confirming a substantial destruction of the MOE. These results show that the MOE is primarily involved in the detection and processing of odors that are used to localize and identify the sex and endocrine status of conspecifics. By contrast, both the main and accessory olfactory systems contribute to female sexual receptivity in female mice.

    In men and women sexual arousal culminates in orgasm, with female orgasm solely from sexual intercourse often regarded as a unique feature of human sexuality. However, orgasm from sexual intercourse occurs more reliably in men than in women likely reflecting the different types of physical stimulation men and women require for orgasm. In men, orgasms are under strong selective pressure as orgasms are coupled with ejaculation and thus contribute to male reproductive success. By contrast, women's orgasms in intercourse are highly variable and are under little selective pressure as they are not a reproductive necessity.. The proximal mechanisms producing variability in women's orgasms are little understood. In 1924 Marie Bonaparte proposed that a shorter distance between a woman's clitoris and her urethral meatus (CUMD) increased her likelihood of experiencing orgasm in intercourse. She based this on her published data which were never statistically analyzed. In 1940 Landis and colleagues published similar data suggesting the same relationship, but these data too were never fully analyzed. We analyzed raw data from these two studies and found that both demonstrate a strong inverse relationship between CUMD and orgasm during intercourse. Unresolved is whether this increased likelihood of orgasm with shorter CUMD reflects increased penile-clitoral contact during sexual intercourse or increased penile stimulation of internal aspects of the clitoris. CUMD likely reflects prenatal androgen exposure, with higher androgen levels producing larger distances. Thus these results suggest that women exposed to lower levels of prenatal androgens are more likely to experience orgasm during sexual intercourse. PMID:21195073

  14. Female song occurs in songbirds with more elaborate female coloration and reduced sexual dichromatism

    Full Text Available Elaborate plumages and songs in male birds provide classic evidence for Darwinian sexual selection. However, trait elaboration in birds is not gender-restricted: female song has recently been revealed as a taxonomically-widespread trait within the songbirds (oscine Passerines, prompting increased research into likely functions and social/ecological correlates. Here we use phylogenetically-informed comparative analysis to test for an evolutionary association between female song and plumage color elaboration in songbirds. If there is an evolutionary trade-off between signaling modes, we predict a negative correlation between acoustic and visual elaboration. This trade-off hypothesis has been commonly proposed in males but has mixed empirical support. Alternatively, if song and plumage have similar or overlapping functions and evolve under similar selection pressures, we predict a positive correlation between female song and female plumage elaboration. We use published data on female song for 1,023 species of songbirds and a novel approach that allows for the reliable and objective comparison of color elaboration between species and genders. Our results reveal a significant positive correlation between female colorfulness and female song presence. In species where females sing, females (but not males are on average more colorful – with concomitantly reduced average sexual dichromatism. These results suggest that female plumage and female song likely evolved together under similar selection pressures and that their respective functions are reinforcing. We discuss the potential roles of sexual versus social selection in driving this relationship, and the implications for future research on female signals.

    Altered states of consciousness lead to profound changes in the sense of self, time and space. We assessed how these changes were related to sexual responsiveness during sex. 116 subjects reported (a) intensity of awareness concerning body, space and time, and (b) satisfaction, desire, arousal, and orgasm occurrence. We differentiated vaginal intercourse orgasm from noncoital orgasm. Female vaginal intercourse orgasm was further differentiated as with or without concurrent clitoral masturbation. Overall, sexual responsiveness was related to greater body awareness and lesser time and space awareness. Satisfaction, desire, and arousal were especially associated with less time awareness in women. Female orgasms during vaginal intercourse were related to greater body awareness and lesser time awareness, but noncoital orgasms were unrelated. Our findings provide empirical support for the hypotheses that altered states of consciousness with attentional absorption are strongly related to sexual responsiveness in women, and to a lesser extent in men.

    Sexually transmitted Chlamydia trachomatis causes infertility, and because almost 90% of infections are asymptomatic, a vaccine is required for its eradication. Mathematical modeling studies have indicated that a vaccine eliciting partial protection (non-sterilizing) may prevent Chlamydia infection transmission, if administered to both sexes before an infection. However, reducing chlamydial inoculum transmitted by males and increasing infection resistance in females through vaccination to elicit sterilizing immunity has yet to be investigated experimentally. Here we show that a partially protective vaccine (chlamydial major outer membrane protein (MOMP) and ISCOMATRIX (IMX) provided sterilizing immunity against sexual transmission between immunized mice. Immunizing male or female mice before an infection reduced chlamydial burden and disease development, but did not prevent infection. However, infection and inflammatory disease responsible for infertility were absent in 100% of immunized female mice challenged intravaginally with ejaculate collected from infected immunized males. In contrast to the sterilizing immunity generated following recovery from a previous chlamydial infection, protective immunity conferred by MOMP/IMX occurred independent of resident memory T cells. Our results demonstrate that vaccination of males or females can further protect the opposing sex, whereas vaccination of both sexes can synergize to elicit sterilizing immunity against Chlamydia sexual transmission.

    While the function of ornaments shaped by sexual selection is to attract mates or drive off rivals, these signals may also evolve through social selection, in which the social context affects the fitness of signallers and receivers. Classical 'mate choice' experiments often reveal preferences for ornaments, but few studies have considered whether these are strictly sexual or reflect general social preferences. Indeed, an alternative possibility is that ornaments evolve through 'non-sexual social selection' (hereafter 'social selection'). We examined the role of ornamentation (yellow ventral patch) and familiarity (individuals recognize group mates with which they have had previous interactions) on mate choice (opposite-sex stimuli preference) and social choice (same-sex stimuli preference) in both male and female white-eyed bulbuls (Pycnonotus xanthopygos). In the mate choice test, females preferred unfamiliar males with increased yellow. There were no biologically important differences in male preferences based on familiarity or intensity of patch colour. In the social choice test, females preferred to associate with familiar females. Males preferred to associate with familiar males but also preferred to associate with less ornamented males. Our results suggest that ornamentation and familiarity are important features, playing different roles in males and females, in both social and sexual selection processes.

    Women experience a decline in estrogen and androgen levels after natural or surgically induced menopause, effects that are associated with a loss of sexual desire and bone mineral density. Studies in our laboratories have shown the beneficial effects of selective androgen receptor modulators (SARMs) in the treatment of osteoporosis and muscle wasting in animal models. A series of S-3-(phenoxy)-2-hydroxy-2-methyl-N-(4-cyano-3-trifluoromethyl-phenyl)-propionamide analogs was synthesized to evaluate the effects of B-ring substitutions on in vitro and in vivo pharmacologic activity, especially female sexual motivation. The androgen receptor (AR) relative binding affinities ranged from 0.1 to 26.5% (relative to dihydrotestosterone) and demonstrated a range of agonist activity at 100 nM. In vivo pharmacologic activity was first assessed by using male rats. Structural modifications to the B-ring significantly affected the selectivity of the SARMs, demonstrating that single-atom substitutions can dramatically and unexpectedly influence activity in androgenic (i.e., prostate) and anabolic (i.e., muscle) tissues. (S)-N-(4-cyano-3-trifluoromethyl-phenyl)-3-(3-fluoro,4-chlorophenoxy)-2-hydroxy-2-methyl-propanamide (S-23) displayed full agonist activity in androgenic and anabolic tissues; however, the remaining SARMs were more prostate-sparing, selectively maintaining the size of the levator ani muscle in castrated rats. The partner-preference paradigm was used to evaluate the effects of SARMs on female sexual motivation. With the exception of two four-halo substituted analogs, the SARMs increased sexual motivation in ovariectomized rats, with potency and efficacy comparable with testosterone propionate. These results indicate that the AR is important in regulating female libido given the nonaromatizable nature of SARMs and it could be a superior alternative to steroidal testosterone preparations in the treatment of hypoactive sexual desire disorder.

    Background We previously reported that the majority of women seeking bariatric surgery had female sexual dysfunction (FSD) as defined by the validated Female Sexual Function Index (FSFI). Objective The current study examined whether FSD resolves after bariatric surgery. Setting The Miriam Hospital, Providence RI, USA. Methods Fifty-four reportedly sexually active women (43.3±9.5 years) completed the FSFI pre- and 6-months post-operatively after a mean excess weight loss (%EWL) of 42.3% [Laparoscopic adjustable gastric banding (LAGB) n=38; %EWL=34.6±15.7; Roux-en-Y gastric bypass (RYGB) n=16; %EWL=60.0±21.2). The FSFI assesses sexual function across six domains with higher scores indicating better sexual function. Summing of these scores yields a FSFI-total score (range=2–36 with ≤26.55=FSD). Results Before surgery, 34 women (63%) had scores indicative of FSD. By 6-months after surgery, FSD had resolved in 23 of these 34 (68%) women, and only 1 woman developed FSD. In the entire sample, there were significant (p<0.05) improvements from pre- to post-surgery on all FSFI domains. FSFI-total scores improved after LAGB (24.2±5.9 to 29.1±4.1, p<0.001) and RYGB (23.7±7.7 to 30.0±4.7, p<0.001). In regression analyses, being married, younger age, and worse preoperative sexual function were related to greater sexual function improvements. Postoperatively, participants’ FSFI-total scores were indistinguishable from published normative controls (29.4±4.3 vs. 30.5±5.3, p=0.18). Conclusion FSD resolved in a large percentage of women. Sexual functioning in the entire sample improved to levels consistent with normative controls. This improvement in sexual function did not depend on surgery type or weight loss amount, and appears to be an additional benefit for women undergoing bariatric surgery. PMID:20678969

    Full Text Available Background & aim: Sexual health education is one of the responsibilities of healthcare workers at schools, which can reduce the risk of sexually transmitted diseases such as AIDS, unwanted pregnancy, abortion, substance abuse, sexual violence, and suicidal tendencies. This study aimed to investigate healthcare workers’ competence in sexual health education for female adolescents at schools. Methods:This cross-sectional study was conducted on 300 healthcare workers, responsible for sexual health education at schools in 2015. A valid and reliable researcher-made questionnaire was completed by the healthcare workers in order to assess their competence in sexual health education at healthcare centers of Khuzestan, Iran. To assess the competence of the participants (i.e., knowledge, attitude, confidence, and performance, descriptive statistics were calculated for quantitative variables. Also, mean, standard deviation, frequency, and percentage were calculated for qualitative variables. Pearson’s correlation test was performed to assess the relationship between the subjects’ knowledge, attitude, confidence, and performance. Also, the association between demographic variables and participants’ knowledge, attitude, confidence, and performance was evaluated, using analysis of variance (ANOVA. Data were analyzed, using SPSS version 21.0. Results: Knowledge, attitude, and confidence of healthcare workers in sexual health education were desirable. However, the subjects showed a poor performance in teaching students the required skills to control their emotions, instincts, homosexual tendencies, and masturbation. There was a significant correlation between performance, attitude, and confidence, knowledge and attitude, performance and confidence, and confidence, performance, and attitude (P

    Almost all research on sexual assault victimization among undergraduate university students pertains to incidents that occur on domestic college and university campuses. The purpose of the present study was to investigate the prevalence of sexual assault victimization and related factors among undergraduates in the context of study-abroad programs. Two hundred eight female students (52% response rate) from a small university in the northeastern United States who had recently studied abroad responded to an online survey containing measures of sexual assault, posttraumatic stress responses (PSR), and alcohol consumption. Almost 19% of the respondents indicated one or more types of sexual assault victimization. Approximately 17% reported non-consensual sexual touching, 7% attempted rape, 4% rape, with 9% reporting attempted rape or rape. As in domestic studies, victimization in this sample was related positively to alcohol consumption and PSR. Use of force was the most frequently reported perpetrator tactic. In sum, the high rates of sexual assault victimization reported by this sample during study abroad replicate previous findings. This context requires further attention from sexual assault researchers, especially given the increasing numbers of university students engaging in study abroad, and from campus support personnel who may be unaware of the likelihood of assault in this context.

    As in any field of research,the study of sexual selection is subject to ongoing debate over definitions and interpretations of the fundamental concepts involved.These arguments generally promote progress,as they highlight areas where current explanations are incomplete.Here we briefly review two ongoing discussions in the sexual selection literature.First,the definition of sexual selection has received renewed interest in light of increasing research effort into when and how it operates in females.Second,how best to measure sexual selection is an ongoing subject of debate; in practice,recognition that the appropriate measures depend on the focus of the specific study,and that multiple measures should be employed wherever possible,seems to provide the most informative approach.The wide scope of recent empirical work in these and related areas,with the application of new techniques and approaches,reflects that the field of sexual selection is being constantly expanded and enriched.

    Fluidity in attractions and behaviors among same-sex attracted women has been well-documented, suggesting the appropriateness of dynamical systems modeling of these phenomena over time. As dynamical systems modeling offer an approach to explaining the patterns of complex phenomena, it may be apt for explaining variability in female same-sex sexuality. The present research is the first application of this analytical approach to such data. Dynamical systems modeling, and specifically generalized local linear approximation modeling, was used to fit daily diary data on same-sex attractions and behaviors over a 21 day period among a group of 33 sexual minority women characterized as lesbian, bisexual or “fluid” based on their identity histories. Daily measures of women’s reported same-sex attractions were fit using a linear oscillator model and its parameters estimated the cyclicity in these attractions. Results supported the existence of a “core sexual orientation” for women in this sample, regardless of how they identified and despite a high degree of variability in daily same-sex attractions. Thus, modeling individual differences in the variability of attractions and behaviors of sexual minority women may be critical to furthering our understanding of female same-sex sexuality and human sexual orientation more broadly.

    Few studies have investigated endorsement of female sexual response models, and no single model has been accepted as a normative description of women's sexual response. The aim of the study was to establish how women from a population-based sample endorse current theoretical models of the female sexual response--the linear models and circular model (partial and composite Basson models)--as well as predictors of endorsement. Accordingly, 174 heterosexual women aged 18-55 years were included in a cross-sectional study: 74 women diagnosed with female sexual dysfunction (FSD) based on DSM-5 criteria and 100 non-dysfunctional women. The description of sexual response models was used to divide subjects into four subgroups: linear (Masters-Johnson and Kaplan models), circular (partial Basson model), mixed (linear and circular models in similar proportions, reflective of the composite Basson model), and a different model. Women were asked to choose which of the models best described their pattern of sexual response and how frequently they engaged in each model. Results showed that 28.7% of women endorsed the linear models, 19.5% the partial Basson model, 40.8% the composite Basson model, and 10.9% a different model. Women with FSD endorsed the partial Basson model and a different model more frequently than did non-dysfunctional controls. Individuals who were dissatisfied with a partner as a lover were more likely to endorse a different model. Based on the results, we concluded that the majority of women endorsed a mixed model combining the circular response with the possibility of an innate desire triggering a linear response. Further, relationship difficulties, not FSD, predicted model endorsement.

    Full Text Available Signa are sclerotized structures located on the inner wall of the corpus bursa of female Lepidoptera whose main function is tearing open spermatophores. The sexually antagonistic coevolution (SAC hypothesis proposes that the thickness of spermatophore envelopes has driven the evolution of the females signa; this idea is based in the fact that in many lepidopterans female sexual receptivity is at least partially controlled by the volume of ejaculate remaining in the corpus bursa. According to the SAC hypothesis, males evolved thick spermatophore envelopes to delay the post-mating recovery of female sexual receptivity thus reducing sperm competition; in response, females evolved signa for breaking spermatophore envelopes faster, gaining access to the resources contained in them and reducing their intermating intervals; the evolution of signa, in turn, favored the evolution of even thicker spermatophore envelopes, and so on. We tested two predictions of the SAC hypothesis with comparative data on the thickness of spermatophore envelopes of eleven species of Heliconiinae butterflies. The first prediction is that the spermatophore envelopes of polyandrous species with signa will be thicker than those of monandrous species without signa. In agreement with this prediction, we found that the spermatophore envelopes of a polyandrous Heliconius species with signa are thicker than those of two monandrous Heliconius species without signa. The second prediction is that in some species with signa males could enforce monandry in females by evolving “very thick” spermatophore envelopes, in these species we predict that their spermatophore envelopes will be thicker than those of their closer polyandrous relatives with signa. In agreement with this prediction, we found that in two out of three comparisons, spermatophore envelopes of monandrous species with signa have thicker spermatophore envelopes than their closer polyandrous relatives with signa.

    Female sexual arousal disorder (FSAD) is the inability to attain or maintain an adequate lubrication-swelling response of sexual excitement. The potentiation of vascular responses leading to increased blood flow in clitoris and vagina has represented the main focus in the pharmacological treatment of FSAD, including the evaluation of the type 5 phosphodiesterase (PDE5) inhibitors. However, due to a lack of clear efficacy, there is no approved pharmacotherapy for FSAD to date. In the present issue of the British Journal of Pharmacology, Wayman et al. show that the administration by intravenous or intravaginal routes of a novel neutral endopeptidase inhibitor, UK-414,445, results in enhanced genital blood flow responses to pelvic nerve stimulation in female rabbits, without significantly affecting blood pressure. Neutral endopeptidase inhibition, by preserving vasoactive peptides such as vasoactive intestinal polypeptide, raises the possibility of a new pharmacological approach to the treatment of FSAD.

    Full Text Available Abstract Background Sexuality is a complex phenomenon that is being influenced by psychological as well as physiological factors. Its dysfunction includes desire, arousal, orgasmic and sex pain disorders. The present study aimed to assess the incidence of sexual dysfunction (SD and related risk factors in a cohort of Ghanaian women. Method The Golombok Rust Inventory of Sexual Satisfaction (GRISS was administered to 400 healthy women between 18 and 58 years old (mean +/- SD: 30.1 +/- 7.9 domiciled in the Kumasi metropolis. Results The response rate was 75.3% after 99 were excluded. Of the remaining 301 women, 50% were engaged in exercise, 26.7% indulge in alcoholic beverages and only 2% were smokers. A total of 62.1% of the women had attained high education, whilst, 28.9% were married. After logistic regression analysis, alcohol emerged (OR: 2.0; CI: 1.0 - 3.8; p = 0.04 as the main risk factor for SD. The overall prevalence of SD in these subjects was 72.8%. Severe difficulties with sexual function were identified in 3.3% of the studied population. The most prevalent areas of difficulty were anorgasmia (72.4%, sexual infrequency (71.4%, dissatisfaction (77.7%, vaginismus (68.1%, avoidance of sexual intercourse (62.5%, non-sensuality (61.5% and non-communication (54.2%. Whereas 8% had severe difficulties with anorgasmia, only 6% had severe difficulties with vaginismus. Conclusion SD affects more than 70% of Ghanaian women who are sexually active. Alcohol significantly influences sexual activity.

    Full Text Available This paper is an empirical research on women's participation in Islamic revivalist movement of Tablighi Jama'at. In the current discourse on religion and female sexuality, I intend to look within Islam, as a religion and as an assertion of identity in the form of Tablighi Jama'at and Tabligh's articulation of its weltanschauung on Muslim way of life, with excessive focus on female sexuality. Here I will discuss Tabligh's conceptualisation of gender and gender roles through my field experience and analysis of women participation in the movement. In recent years we see that there is an upsurge in religious movements across the world exerting their identities and attempting to claim their rights. Since women have always been central to the political and social imagination of the Muslim mind we see an increased level of women's participation in these movements with defined sexual morality and gender equality. It is through the role of women in the transnational Islamic revivalist movement of Tablighi Jama'at, which arose as a response to Christian missionary and Hindu revivalist movements in the early 1920's in pre-partition India, that I have explored their level of engagement and their practices in order to bring into light tabligh's understanding of the female agency in the Muslim social order. In the backdrop of the feminist project and keeping in view tabligh's Orientalist understanding of the female, I raise the following questions, 'Is Tablighi Jama'at another such assertion within Islam that prescribes laws to define and control the female sexual desire through their understanding of sexuality and gender relations? Is the female tabligh member an agent of 'reform' or is she 'socialized' to believe that that men are superior and that what is described as masculine precedes and has priority over the feminine?

    Previous studies from our laboratory investigated the effects of picrotoxin (PT), a γ-aminobutyric acid receptor antagonist administered during several perinatal periods, on the sexual behavior of male and female rats. We observed that the time of perinatal exposure to PT is critical to determine either facilitation or impairment of sexual behavior. The present study evaluated the effects of prenatal administration of a single dose of PT on gestation day 18 of dams (the first critical period of male brain sexual differentiation) on sexual behavior of male and female offspring. Thus, female Wistar rats were mated with males and, on gestation day 18, received 0.6 mg/kg of PT or 0.9% saline solution subcutaneously. On postnatal day 1, the offspring were weighed and several measures of sexual development were assessed. The sexual behaviors and the general activity in the open field of adult male and ovariectomized, hormone-treated female rats were observed. On comparison with the control group, maternal PT treatment: (i) did not alter the maternal weight, pup weight, anogenital distance, or male and female general activity; (ii) increased female sexual behavior, that is, decreased the latencies to first mount, first lordosis, and tenth lordosis, and the percentage of females presenting lordosis; and (iii) did not alter male sexual behavior. It is suggested that prenatal PT exposure interfered with epigenetic mechanisms related to the development of sex differences in the brain, leading to the observed sexually dimorphic effects on sexual behavior.

  12. The politics of sex research and constructions of female sexuality: what relevance to sexual health work with young women?

    By examining the relationship between the cultural construction of female sexuality and the lack of potential for many young heterosexual women to be truly sexually healthy this paper submits that messages for women within HIV prevention programmes can be confused, confining and at times dangerous to women's health and well-being. It is suggested that these messages also reinforce a traditional, biologically determined medical understanding of female sexuality that does not take note of social or culturally based research or commentary on female experience or female desire, but rather confines many women to sexual restrictions, doing little to empower women to prevent sexual risk-taking. The ideological basis of the discussion within this paper is informed by the awareness that applications and understandings of 'sexuality' are diverse and contested within sex research traditions and will influence the choice of research concerns. The 'deterministic' explanation of sexuality that 'sexuality' (the abstract noun referring to the quality of being 'sexual', Williams 1983) is your fate or destiny and that biology causes the patterns of sexual life, is abandoned in this paper in favour of a search for a definition of sexuality which brings together a host of different biological and mental possibilities which are given meaning only in social relations. This allows for a framework for the study of sexuality that relates it to other social phenomena, particularly economic, political and social structures (Foucault 1979); in other words, a study of the 'social construction' of sexuality. This paper suggests that health care professionals need to develop an awareness of the diversities within female sexuality and gain insight into their own values and assumptions about female sexuality if these are not to inhibit effective approaches and interventions in the areas of HIV and sexual health.

    We investigated the sexual values, attitudes, and behaviors of 30 Somali female refugees living in a large metropolitan area of Minnesota by collecting exploratory sexual health information based on the components of the sexual health model-components posited to be essential aspects of healthy human sexuality. A Somali-born bilingual interviewer conducted the semistructured interviews in English or Somali; 22 participants chose to be interviewed in Somali. Interviews were translated, transcribed, and analyzed using descriptive statistics and thematic analyses. Our study findings highlighted a sexually conservative culture that values sexual intimacy, female and male sexual pleasure, and privacy in marriage; vaginal sexual intercourse as the only sanctioned sexual behavior; and the importance of Islamic religion in guiding sexual practices. Findings related to human immunodeficiency virus (HIV) revealed HIV testing at immigration, mixed attitudes toward condom use, and moderate knowledge about HIV transmission modes. Female genital cutting (FGC) was a pervasive factor affecting sexual functioning in Somali women, with attitudes about the controversial practice in transition. We recommend that health professionals take the initiative to discuss sexual health care and safer sex, sexual behaviors/functioning, and likely challenges to sexual health with Somali women--as they may be unlikely to broach these subjects without permission and considerable encouragement.

  14. Female postmating immune responses, immune system evolution and immunogenic males.

    Females in many taxa experience postmating activation of their immune system, independently of any genital trauma or pathogenic attack arising from male-female genital contact. This response has always been interpreted as a product of natural selection as it either prepares the female immune system for antigens arising from an implanted embryo (in the case of placental mammals), or is a "pre-emptive strike" against infection or injury acquired during mating. While the first hypothesis has empirical support, the second is not entirely satisfactory. Recently, studies that have experimentally dissected the postmating responses of Drosophila melanogaster females point to a different explanation: male reproductive peptides/proteins that have evolved in response to postmating male-male competition are directly responsible for activating particular elements of the female immune system. Thus, in a broad sense, males may be said to be immunogenic to females. Here, we discuss a possible direct role of sexual selection/sexual conflict in immune system evolution, in contrast to indirect trade-offs with other life-history traits, presenting the available evidence from a range of taxa and proposing ways in which the competing hypotheses could be tested. The major implication of this review is that immune system evolution is not only a product of natural selection but also that sexual selection and potentially sexual conflict enforces a direct selective pressure. This is a significant shift, and will compel researchers studying immune system evolution and ecological immunity to look beyond the forces generated by parasites and pathogens to those generated by the male ejaculate.

  15. Female mate preference explains countergradient variation in the sexual coloration of guppies (Poecilia reticulata).

    We tested the hypothesis that mate choice is responsible for countergradient variation in the sexual coloration of Trinidadian guppies (Poecilia reticulata). The nature of the countergradient pattern is that geographical variation in the carotenoid content of the orange spots of males is counterbalanced by genetic variation in drosopterin production, resulting in a relatively uniform pigment ratio. A female hue preference could produce this pattern, because hue is the axis of colour variation most directly affected by the pigment ratio. To test this hypothesis, we crossed two populations differing in drosopterin production and produced an F(2) generation with variable drosopterin levels. When the carotenoid content of the orange spots was held constant, female guppies preferred males with intermediate drosopterin levels. This shows that females do not simply prefer males with greater orange spot pigment content; instead, the ratio of the pigments also affects male attractiveness. To our knowledge, this is the first direct evidence for a hypothesized agent of countergradient sexual selection.

    Over the past decades, research attention has increasingly been paid to the neurobiological component of sexual behavior. The aim of the present study was to investigate the correlation of estrogen receptor α (ERA) gene polymorphism (rs2234693-PvuII) (T→C substitution) and oxytocin receptor gene polymorphism (rs53576) (G→A substitution) with sexuality parameters of young, healthy women. One hundred thirty-three Greek heterosexual women, students in higher education institutions, 20-25 years of age, sexually active, with normal menstrual cycles (28-35 days), were recruited in the study. Exclusion criteria were chronic and/or major psychiatric diseases, use of oral contraceptive pills (OCs), polycystic ovary syndrome (PCOS), thyroid diseases as well as drugs that are implicated in hypothalamus-pituitary-gonadal axis. T allele (wildtype) of rs2234693 (PvuII) polymorphism of ERA gene was correlated with increased levels of arousal and lubrication, whereas A allele (polymorphic) of rs53576 (OXTR) polymorphism was correlated with increased arousal levels. The simultaneous presence of both T allele of rs2234693 (PvuII) and A allele of rs53576 (OXTR) polymorphisms (T + A group) was correlated with increased arousal, orgasm levels as well as female sexual function index full score. To our knowledge, this is the first study to investigate the interaction between ERA and OXTR with regard to sexual function in women. Female sexuality is a complex behavioral trait that encompasses both biological and psychological components. It seems that variability in female sexual response stems from genetic variability that characterizes endocrine, neurotransmitter and central nervous system influences.

    Introduction Intrauterine Device (IUD) is the most preferred modern contraceptive method in Turkey. Female Sexual Dysfunction (FSD) is defined as lack of one or more of the components in the sexual response cycle which includes sexual desire, impaired arousal and inability achieving an orgasm or pain with intercourse. FSD has multi-factorial aetiology. Advanced age and menopause, fatigue and stress, psychiatric and neurologic disease, childbirth, pelvic floor or bladder dysfunction, endometriosis, uterine fibroids, hypertension obesity, medication and substances, hormonal contraceptives, relationship factors are known risk factors for FSD. Aim To investigate if IUD has any impact on female sexual functioning. Materials and Methods In this cross-sectional study subjects were divided into two groups. Study group consisted of 92 IUD-users (mean 5.1±1.2 years) and the control group consisted of 83 women with no contraception. Female Sexual Function Index (FSFI) questionnaire was performed to both two groups. Women with a total score lower than 26.5 were considered as having sexual dysfunction. Results The prevalence of FSD was 57.1% among participants. IUD users had a lower total FSFI score comparing to control group but the difference was not statistically different (p=0.983). A positive correlation was found between total FSFI score and duration of IUD (p=0.003). Conclusion No difference was found in terms of sexual dysfunction between IUD users and women with no contraception. The prevalence of FSD was very high in both groups which may be attributed to the socio-cultural factors such as embarrassment of women due to conservatism. PMID:27891404

    We sought to evaluate patient adherence and response to simple vaginal and sexual health treatment strategies in female cancer patients receiving treatment at a female sexual medicine and health program and identify improvements of physical symptoms, per patient and clinical evaluation. Evaluability criteria included gynecologic exam at initial visit, at least one follow-up with gynecologic exam within 8 months of initial visit, and all consecutive follow-ups cancers. An assessment form included a clinician evaluation, Vaginal Assessment Scale (VAS), Vulvar Assessment Scale (VuAS), and patient-reported outcomes. Compliance with treatment recommendations were summarized, and changes over time were compared for clinical outcomes. Mean number of visits was 3.43. Mean age was 55.4 years; 92 % (n = 155/169) were in menopause. Treatment strategies included rationale and instruction for use of vaginal moisturizers, lubricants, pelvic floor exercises, and dilator therapy, in addition to psychosexual education regarding sexual changes (response, anatomy, and function) associated with cancer treatment and support. At last assessment, 89 % had complied with the clinical recommendation (moisturize 2-5+ times/week). Vaginal pH scores >6.5 declined over time (p = 0.03). VAS scores improved by last assessment (p vaginal health concerns decreased (p = 0.00003). Significant changes were observed in women using treatment strategies, with improvement in vulvovaginal symptoms, a decrease in elevated vaginal pH and pain with exams, enhanced sexual function, and increased intimacy confidence. These findings have high clinical relevance for symptom management with improvement of sexual function using simple strategies and clinical tools in the oncology setting.

    Childhood sexual trauma has been demonstrated to increase survivors' risk for engaging in unrestricted sexual behaviors and experiencing adolescent sexual assault. The current study used the sexual self-schema construct to examine cognitive representations of sexuality that might drive these behavioral patterns. In Study 1 (N = 774), we attempted to improve the content validity of the Sexual Self Schema Scale for child sexual abuse (CSA) survivors, introducing a fourth sexual self-schema factor titled the "immoral/irresponsible" factor. In Study 2 (N = 1150), the potential differences in sexual self-views, as assessed by the four sexual self-schema factors, between CSA survivors and non-victims were explored. In addition, Study 2 evaluated how these sexual self-schema differences may contribute to participation in unrestricted sexual behaviors and risk for sexual assault in adolescence. Results indicated that a history of CSA impacted the way women viewed themselves as a sexual person on each of the four factors. CSA survivors were found to view themselves as more open and possessing more immoral/irresponsible cognitions about sexuality as compared to women who did not have a CSA history. In addition, the CSA survivors endorsed less embarrassment and passionate/romantic views of their sexual selves. The interaction of CSA severity and the sexual self-schemas explained variance in adolescent sexual assault experiences above and beyond the severity of CSA history and participation in risky sexual behaviors. The findings suggest that sexual self-views may serve to moderate the relationship between CSA and adolescent sexual assault. Implications of these findings and directions for future research are discussed.

    Researchers traditionally have assumed that sex reassignment procedures do not change sexual orientation. Of 20 transsexuals of various types that were interviewed, 6 heterosexual male-to-female transsexual respondents reported that their sexual orientation had changed since transitioning from male to female. These respondents stated that before transitioning they had been sexually orientated towards females. After transitioning, these same respondents reported that they were sexually orientated towards males. Five of the six respondents reported having various sexual encounters with males since transitioning. The respondents explained the changes in their sexual orientation as part of their emerging female gender identities. Three of the respondents claimed that the use of female hormones played a role in changing their sexual orientation. It did not appear that the respondents' post-transitional sexual attractions towards males were similar to autogynephilic images and fantasies described by Blanchard (1991).

    Full Text Available Abstract Background Mutarotases are recently characterized family of enzymes that are involved in the anomeric conversions of monosaccharides. The mammalian fucose mutarotase (FucM was reported in cultured cells to facilitate fucose utilization and incorporation into protein by glycosylation. However, the role of this enzyme in animal has not been elucidated. Results We generated a mutant mouse specifically lacking the fucose mutarotase (FucM gene. The FucM knockout mice displayed an abnormal sexual receptivity with a drastic reduction in lordosis score, although the animals were fertile due to a rare and forced intromission by a typical male. We examined the anteroventral periventricular nucleus (AVPv of the preoptic region in brain and found that the mutant females showed a reduction in tyrosine hydoxylase positive neurons compared to that of a normal female. Furthermore, the mutant females exhibited a masculine behavior, such as mounting to a normal female partner as well as showing a preference to female urine. We found a reduction of fucosylated serum alpha-fetoprotein (AFP in a mutant embryo relative to that of a wild-type embryo. Conclusions The observation that FucM-/- female mouse exhibits a phenotypic similarity to a wild-type male in terms of its sexual behavior appears to be due to the neurodevelopmental changes in preoptic area of mutant brain resembling a wild-type male. Since the previous studies indicate that AFP plays a role in titrating estradiol that are required to consolidate sexual preference of female mice, we speculate that the reduced level of AFP in FucM-/- mouse, presumably resulting from the reduced fucosylation, is responsible for the male-like sexual behavior observed in the FucM knock-out mouse.

    In this paper, we review research related to female homosexual behavior in Japanese macaques (Macaca fuscata), including our 20-year program of research on this species. Multiple lines of evidence indicate that female homosexual behavior in this species is sexually motivated. In contrast, many sociosexual hypotheses have been tested in relation to female homosexual behavior in Japanese macaques, but none have been supported. Female Japanese macaques sometimes engage in same-sex sexual activity even when motivated opposite-sex alternatives are available. Within this context of mate choice, males compete inter-sexually for opportunities to copulate with females above and beyond any intra-sexual competition that is required. Anecdotal evidence suggests that inter-sexual competition for female sexual partners has been observed in a number of other species, including humans. At present it is unclear whether inter-sexual competition for sexual partners influences patterns of reproduction. Our understanding of sexual selection and the evolution of mating systems may be improved by investigating whether inter-sexual mate competition influences the acquisition and maintenance of reproductive partners in those species in which such interactions occur.

    Female Genital Mutilation/Cutting (FGM/C) or female circumcision is the procedure of eliminating some or all parts of the external female genitalia. FGM/C is carried out by traditional circumcisers. They usually use cutting tools like a blade or straight-razor. Although FGM/C is well described in the African continent and some Arabic countries, data from Iran are scarce. The major objective of this current study was to investigate the effects of FGM/C on the female sexual function of married women compared to the non-circumcised women in the Kurdistan province of Iran. A case-control study was conducted in a sample of 280 married women (140 circumcised-women and 140 non-circumcised-women) who referred to the healthcare centers for vaccination, midwifery, or family planning services. Participants were requested to complete the Persian-translated version of the Female Sexual Function Index. The total score of the FSFI and its individual domains. Of the circumcised women, 51.4% reported circumcision procedures before the age of 3 years. Religion motivation (53.6%) was mentioned as the most important factor for the family leading to FGM/C. Almost all operations were performed by traditional circumcisers. Non-circumcised women had significantly higher Persian-FSFI total score (25.3 ± 4.34) compared to the circumcised women (17.9 ± 5.39). Sexual function in women with FGM/C is adversely altered. In Kurdistan province women, FGM/C is associated with reduction of scores of Persian-FSFI on all domain scores. Education in general and informing the people that FGM/C is not a religious Hadith certainly would have a great impact on the suffering of the women from FGM/C as well as the level of "desire, arousal, lubrication, orgasm, satisfaction, and pain in the sexual function of women".

    2013-01-01

    This review, with 21 figures and 1 video, aims to clarify some important aspects of the anatomy and physiology of the female erectile organs (triggers of orgasm), which are important for the prevention of female sexual dysfunction. The clitoris is the homologue of the male's glans and corpora cavernosa, and erection is reached in three phases: latent, turgid, and rigid. The vestibular bulbs cause "vaginal" orgasmic contractions, through the rhythmic contraction of the bulbocavernosus muscles. Because of the engorgement with blood during sexual arousal, the labia minora become turgid, doubling or tripling in thickness. The corpus spongiosum of the female urethra becomes congested during sexual arousal; therefore, male erection equals erection of the female erectile organs. The correct anatomical term to describe the erectile tissues responsible for female orgasm is the female penis. Vaginal orgasm and the G-spot do not exist. These claims are found in numerous articles that have been written by Addiego F, Whipple B, Jannini E, Buisson O, O'Connell H, Brody S, Ostrzenski A, and others, have no scientific basis. Orgasm is an intense sensation of pleasure achieved by stimulation of erogenous zones. Women do not have a refractory period after each orgasm and can, therefore, experience multiple orgasms. Clitoral sexual response and the female orgasm are not affected by aging. Sexologists should define having sex/love making when orgasm occurs for both partners with or without vaginal intercourse.

    Studies in female sexual assertiveness have generally focused on individuals rather than couples, and little research has been conducted in the Chinese context. This study examined perceived and actual female sexual assertiveness at the couple level, and also explored its impact on marital and sexual satisfaction with a representative sample of 770 couples in Hong Kong. The results showed that husbands reported a higher level of acceptance of female sexual assertiveness in both perception and actual behavior; furthermore, couples reported greater congruence in their perception of female sexual initiation than actual behavior. Multiple logistic regressions showed that actual female sexual assertiveness, not the perception of it, affects both spouses' marital and sexual satisfaction. Compared with couples in which neither accepted female sexual initiation in practice, husbands where both spouses accepted this were more likely to be satisfied with the marriage. Husbands who accepted female sexual refusal whilst their wives did not were also more likely to be satisfied with both the marital and sexual relationship. Similarly, wives who did accept female sexual assertiveness but whose husbands did not were more likely to be satisfied with both the marital and sexual relationship.

    Previous studies have demonstrated variable influences of sexual hormonal states on female brain activation and the necessity to control for these in neuroimaging studies. However, systematic investigations of these influences, particularly those of hormonal contraceptives as compared to the physiological menstrual cycle are scarce. In the present study, we investigated the hormonal modulation of neural correlates of erotic processing in a group of females under hormonal contraceptives (C group; N = 12), and a different group of females (nC group; N = 12) not taking contraceptives during their mid-follicular and mid-luteal phases of the cycle. We used functional magnetic resonance imaging to measure hemodynamic responses as an estimate of brain activation during three different experimental conditions of visual erotic stimulation: dynamic videos, static erotic pictures, and expectation of erotic pictures. Plasma estrogen and progesterone levels were assessed in all subjects. No strong hormonally modulating effect was detected upon more direct and explicit stimulation (viewing of videos or pictures) with significant activations in cortical and subcortical brain regions previously linked to erotic stimulation consistent across hormonal levels and stimulation type. Upon less direct and less explicit stimulation (expectation), activation patterns varied between the different hormonal conditions with various, predominantly frontal brain regions showing significant within- or between-group differences. Activation in the precentral gyrus during the follicular phase in the nC group was found elevated compared to the C group and positively correlated with estrogen levels. From the results we conclude that effects of hormonal influences on brain activation during erotic stimulation are weak if stimulation is direct and explicit but that female sexual hormones may modulate more subtle aspects of sexual arousal and behaviour as involved in sexual expectation.

    THE NEED FOR PREVENTION: Women throughout the world face a growing risk of infection with HIV. Consistent condom use, one cornerstone of primary prevention strategy, is not always feasible for many women. Consequently, women urgently need infection prevention technology that is within their personal control. This session will review current efforts to develop and test female-controlled methods for preventing sexual transmission of HIV and other sexually transmitted pathogens. Both physical and chemical methods will be summarized, including recent findings concerning the efficacy and acceptability of the vaginal pouch (female condom), as well as an overview of research on vaginal microbicides. Data from studies of existing over-the-counter spermicides will be reviewed. The wide range of novel microbicidal products currently being evaluated in the laboratory and early clinical trials demonstrate the breadth of possibilities presented by chemical barrier methods. However, formidible challenges face public and private sector research and development efforts. This session will conclude by highlighting several issues related to the clinical evaluation and introduction of female-controlled prevention technology.

    The aim of this study was to investigate attachment styles in a group of women and men with sexual dysfunction. We recruited 44 subjects (21 women and 23 men) with sexual dysfunction and 41 subjects (21 women and 20 men) with healthy sexual function as the control group. Validated instruments for the evaluation of male and female sexual dysfunctions (M/F SD) and a psychometric tool specifically designed to investigate attachment style were administered. In women, significant differences were found between subjects with sexual dysfunction and healthy controls. The scales indicating an insecure attachment showed: discomfort with closeness (FSD = 42.85 ± 11.55 vs CTRL = 37.38 ± 8.54; P < 0.01), relationship as secondary (FSD = 26.76 ± 2.60 vs CTRL = 18.42 ± 7.99; P < 0.01), and need for approval (FSD=26.38 ± 3.61 vs CTRL = 20.76 ± 7.36; P < 0.01). Healthy women also had significantly higher scores in secure attachment (confidence: FSD = 24.57 ± 3.89 vs CTRL = 33.42 ± 5.74; P < 0.01). Men with sexual dysfunctions differed from healthy men in confidence (MSD = 30 ± 6.33 vs CTRL = 36.05 ± 5.26; P < 0.01) and in discomfort with closeness (MSD = 39.08 ± 8 vs CTRL = 34.25 ± 7.54; P < 0.05). These results suggest that particular aspects related to insecure attachment have a determinant role in people with sexual dysfunctions. It is therefore fundamental to identify the attachment styles and relational patterns in patients receiving counselling and psychological treatments focussed on sexual problems.

    The trafficking of women and girls for sexual exploitation is an internationally recognised form of gender-based violence, and is thought to confer unique sexual and reproductive health vulnerabilities. To date, little research has compared sexual risk or health outcomes among female sex workers (FSWs) on the basis of experiences of sex trafficking. To compare experiences of sexual risk and sexual and reproductive health outcomes among FSWs on the basis of experiences of trafficking as an entry mechanism to sex work. Data from a national sample of FSWs in Thailand (n=815) was used to assess (a) the prevalence of sex trafficking as an entry mechanism into sex work and (b) associations of sex trafficking with sexual risk and health outcomes. Approximately 10% of FSWs met criteria for trafficking as an entry mechanism to sex work. Compared with their non-trafficked counterparts, sex-trafficked FSWs were more likely to have experienced sexual violence at initiation to sex work (adjusted risk ratio (ARR) 2.29, 95% CI 1.11 to 4.72), recent workplace violence or mistreatment (ARR 1.38, 95% CI 1.13 to 1.67), recent condom failure (ARR 1.80, 95% CI 1.15 to 2.80), condom non-use (ARR 3.35, 95% CI 1.49 to 7.52) and abortion (ARR 2.83, 95% CI 1.48 to 5.39). Both the prevalence of sex trafficking as an entry mechanism to sex work and the threats to sexual and reproductive health observed on the basis of trafficking status show the need for comprehensive efforts to identify and support this vulnerable population. Moreover, existing STI/HIV-prevention programming may be stymied by the limited condom-use capacity and high levels of violence observed among those trafficked into sex work.

  14. Sex differences in the neural circuit that mediates female sexual receptivity

    Female sexual behavior in rodents, typified by the lordosis posture, is hormone-dependent and sex-specific. Ovarian hormones control this behavior via receptors in the hypothalamic ventromedial nucleus (VMH). This review considers the sex differences in the morphology, neurochemistry and neural circuitry of the VMH to gain insights into the mechanisms that control lordosis. The VMH is larger in males compared with females, due to more synaptic connections. Another sex difference is the responsiveness to estradiol, with males exhibiting muted, and in some cases reverse, effects compared with females. The lack of lordosis in males may be explained by differences in synaptic organization or estrogen responsiveness, or both, in the VMH. However, given that damage to other brain regions unmasks lordosis behavior in males, a male-typical VMH is unlikely the main factor that prevents lordosis. In females, key questions remain regarding the mechanisms whereby ovarian hormones modulate VMH function to promote lordosis. PMID:21338620

  15. A comparison of 19th century and current attitudes to female sexuality.

    The 19th century medical attitude to normal female sexuality was cruel, with gynecologists and psychiatrists leading the way in designing operations for the cure of the serious contemporary disorders of masturbation and nymphomania. The gynecologist Isaac Baker Brown (1811-1873) and the distinguished endocrinologist Charles Brown-Séquard (1817-1894) advocated clitoridectomy to prevent the progression to masturbatory melancholia, paralysis, blindness and even death. Even after the public disgrace of Baker Brown in 1866-7, the operation remained respectable and widely used in other parts of Europe. This medical contempt for normal female sexual development was reflected in public and literary attitudes. Or perhaps it led and encouraged public opinion. There is virtually no novel or opera in the last half of the 19th century where the heroine with 'a past' survives to the end. H. G. Wells's Ann Veronica and Richard Strauss's Der Rosenkavalier, both of which appeared in 1909, broke the mould and are important milestones. In the last 50 years new research into the sociology, psychology and physiology of sexuality has provided an understanding of decreased libido and inadequate sexual response in the form of hypoactive sexual desire disorder. This is now regarded as a disorder worthy of treatment, either by various forms of counseling or by the use of hormones, particularly estrogens and testosterone.

    Sexually transmitted diseases have the greatest impact on the health of women. They are frequently asymptomatic, so screening for infection is important in preventing the long-term sequelae which include infertility, ectopic pregnancy, and chronic pelvic pain. HIV continues to increase in the female population and the gynecologic complications associated with it are unique to this population. Use of zidovudine in pregnant HIV-infected women has substantially decreased the rate of vertical transmission of HIV infection. The epidemiologic synergy between HIV and STDs is well recognized and prevention of one is dependent on prevention of the other.

  17. Female burying beetles benefit from male desertion: sexual conflict and counter-adaptation over parental investment.

    Directory of Open Access Journals (Sweden)

    Giuseppe Boncoraglio

    Full Text Available Sexual conflict drives the coevolution of sexually antagonistic traits, such that an adaptation in one sex selects an opposing coevolutionary response from the other. Although many adaptations and counteradaptations have been identified in sexual conflict over mating interactions, few are known for sexual conflict over parental investment. Here we investigate a possible coevolutionary sequence triggered by mate desertion in the burying beetle Nicrophorus vespilloides, where males commonly leave before their offspring reach independence. Rather than suffer fitness costs as a consequence, our data suggest that females rely on the male's absence to recoup some of the costs of larval care, presumably because they are then free to feed themselves on the carcass employed for breeding. Consequently, forcing males to stay until the larvae disperse reduces components of female fitness to a greater extent than caring for young singlehandedly. Therefore we suggest that females may have co-evolved to anticipate desertion by their partners so that they now benefit from the male's absence.

    Full Text Available BACKGROUND: Female sexual dysfunction (FSD is an important but controversial problem with serious negative impact on women's quality of life. Data from twin studies have shown a genetic contribution to the development and maintenance of FSD. METHODOLOGY/PRINCIPAL FINDINGS: We performed a genome-wide association study (GWAS on 2.5 million single-nucleotide polymorphisms (SNPs in 1,104 female twins (25-81 years of age in a population-based register and phenotypic data on lifelong sexual functioning. Although none reached conventional genome-wide level of significance (10 × -8, we found strongly suggestive associations with the phenotypic dimension of arousal (rs13202860, P = 1.2 × 10(-7; rs1876525, P = 1.2 × 10(-7; and rs13209281 P = 8.3 × 10(-7 on chromosome 6, around 500 kb upstream of the locus HTR1E (5-hydroxytryptamine receptor 1E locus, related to the serotonin brain pathways. We could not replicate previously reported candidate SNPs associated with FSD in the DRD4, 5HT2A and IL-1B loci. CONCLUSIONS/SIGNIFICANCE: We report the first GWAS of FSD symptoms in humans. This has pointed to several "risk alleles" and the implication of the serotonin and GABA pathways. Ultimately, understanding key mechanisms via this research may lead to new FSD treatments and inform clinical practice and developments in psychiatric nosology.

  20. Extinction and renewal of conditioned sexual responses.

    Mirte Brom

    Full Text Available INTRODUCTION: Extinction involves an inhibitory form of new learning that is highly dependent on the context for expression. This is supported by phenomena such as renewal and spontaneous recovery, which may help explain the persistence of appetitive behavior, and related problems such as addictions. Research on these phenomena in the sexual domain is lacking, where it may help to explain the persistence of learned sexual responses. METHOD: Men (n = 40 and women (n = 62 participated in a differential conditioning paradigm, with genital vibrotactile stimulation as US and neutral pictures as conditional stimuli (CSs. Dependent variables were genital and subjective sexual arousal, affect, US expectancy, and approach and avoid tendencies towards the CSs. Extinction and renewal of conditioned sexual responses were studied by context manipulation (AAA vs. ABA condition. RESULTS: No renewal effect of genital conditioned responding could be detected, but an obvious recovery of US expectancy following a context change after extinction (ABA was demonstrated. Additionally, women demonstrated recovery of subjective affect and subjective sexual arousal. Participants in the ABA demonstrated more approach biases towards stimuli. CONCLUSIONS: The findings support the context dependency of extinction and renewal of conditioned sexual responses in humans. This knowledge may have implications for the treatment of disturbances in sexual appetitive responses such as hypo- and hypersexuality.

  1. Female Sex Offenders and Pariah Femininities: Rewriting the Sexual Scripts

    2014-01-01

    Full Text Available This paper aims to analyze the way in which the media reports of sex offences tend to reinforce traditional sexual scripts and gender identities. Compared to investigations into male sex offenders, female sex offending is relatively underresearched, undertheorized, and misunderstood (Hayes and Carpenter, 2013. We argue that the media’s reinforcement of traditional scripts has hindered the development of awareness of sex offending by women, depicting them as aberrations, that is, as “female pariahs.” As Harris (2010 notes, female sex crimes cannot be explained by male theories of crime. To address this issue, we examined 487 media reports from Australia and the United Kingdom and found that, as key stakeholders in public debate, the media does indeed play a crucial role in shaping the public perceptions of female sex offenders as aberrations and pariahs. This distorted view influences approaches to understanding and acknowledging sex offending by women as well as hindering the safe and timely reporting of offences by victims.

    The medial prefrontal cortex (mPFC) plays a role in anticipation of rewards and goal orientation, properties that are influenced by cocaine administration. Single-unit firing was measured in the mPFC of seven male rats during the expression of approach responses toward a sexually receptive female. Nose-poking in male rats was used as a measure of approach behavior during the following periods: a baseline, first exposure to a female, a second baseline 2 h later and a second exposure to female 10 min after cocaine (15 mg kg⁻¹ i.p.). Two types of excitatory responses were identified. First, a subset of cells (23%) showed increased firing activity during nose-poke behavior upon presentation of the female, but not before. Another subset of cells (12%) showed increased firing in the presence of the female only after cocaine was administered. The present results provide preliminary evidence for neurons in the mPFC that are involved in sexually motivated approach behavior and that are modulated by cocaine.

    Prior research has documented favorable effects of active and educational videogames among adolescents. However, research on potential negative effects of such games is limited. Scholars have called attention to games portraying sexualized female characters. The purpose of the current study was to experimentally investigate the effect of playing a videogame with a sexualized female character on adolescents' acceptance of rape myths and tolerance for sexual harassment. Fifty-seven secondary school pupils, 12-15 years of age, participated in a 2 (gender: boys versus girls)×2 (game character: nonsexualized versus sexualized female) factorial design experiment. Participants played a game for 15 minutes and were randomly assigned to one of the two game characters. Afterward, they completed established scales to assess rape myth acceptance and tolerance for sexual harassment. Analyses of variance showed greater acceptance of rape myths (P=0.039) and greater tolerance of sexual harassment (P=0.046) in adolescents who played with the sexualized woman compared with adolescents in the control condition. We did not find significant differences between boys and girls or any interaction effect between gender and game character. Findings suggest that gameplaying with a sexualized woman may increase adolescents' acceptance of rape myths and tolerance for sexual harassment. These findings highlight attention to the use of sexualized female game characters in (educational and active) videogames that target adolescents.

  4. Female mice deficient in alpha-fetoprotein show female-typical neural responses to conspecific-derived pheromones.

    Directory of Open Access Journals (Sweden)

    Olivier Brock

    Full Text Available The neural mechanisms controlling sexual behavior are sexually differentiated by the perinatal actions of sex steroid hormones. We recently observed using female mice deficient in alpha-fetoprotein (AFP-KO and which lack the protective actions of AFP against maternal estradiol, that exposure to prenatal estradiol completely defeminized the potential to show lordosis behavior in adulthood. Furthermore, AFP-KO females failed to show any male-directed mate preferences following treatment with estradiol and progesterone, indicating a reduced sexual motivation to seek out the male. In the present study, we asked whether neural responses to male- and female-derived odors are also affected in AFP-KO female mice. Therefore, we compared patterns of Fos, the protein product of the immediate early gene, c-fos, commonly used as a marker of neuronal activation, between wild-type (WT and AFP-KO female mice following exposure to male or estrous female urine. We also tested WT males to confirm the previously observed sex differences in neural responses to male urinary odors. Interestingly, AFP-KO females showed normal, female-like Fos responses, i.e. exposure to urinary odors from male but not estrous female mice induced equivalent levels of Fos protein in the accessory olfactory pathways (e.g. the medial part of the preoptic nucleus, the bed nucleus of the stria terminalis, the amygdala, and the lateral part of the ventromedial hypothalamic nucleus as well as in the main olfactory pathways (e.g. the piriform cortex and the anterior cortical amygdaloid nucleus, as WT females. By contrast, WT males did not show any significant induction of Fos protein in these brain areas upon exposure to either male or estrous female urinary odors. These results thus suggest that prenatal estradiol is not involved in the sexual differentiation of neural Fos responses to male-derived odors.

    The etiology of low female sexual desire, the most prevalent sexual complaint in women, is multi-determined, implicating biological and psychological factors, including women's early parent-child relationships and bodily self-representations. The current study evaluated a model that hypothesized that sexual body self-representations (sexual subjectivity, self-objectification, genital self-image) explain (i.e., mediate) the relation between internalized working models of parent-child relationships (attachment, separation-individuation, parental identification) and sexual desire in heterosexual women. We recruited 614 young, heterosexual women (M = 25.5 years, SD = 4.63) through social media. The women completed an online survey. Structural equation modeling was used. The hypotheses were supported in that the relation between internalized working models of parent-child relationships (attachment and separation-individuation) and sexual desire was mediated by sexual body self-representations (sexual body esteem, self-objectification, genital self-image). However, parental identification was not related significantly to sexual body self-representations or sexual desire in the model. Current findings demonstrated that understanding female sexual desire necessitates considering women's internalized working models of early parent-child relationships and their experiences of their bodies in a sexual context. Treatment of low or absent desire in women would benefit from modalities that emphasize early parent-child relationships as well as interventions that foster mind-body integration.

    Disease classification is an important part in the process of medicalisation and one important tool by which medical authority is exerted. The demand for, or proposal of a diagnosis may be the first step in casting life's experiences as medical in nature. Aronowitz has written about how diagnoses result from social framing mechanisms (2008) and consensus (2001), while Brown (1995) has demonstrated a complex range of interactions between lay and professionals, institutions and industries which underpin disease discovery. In any case, there are numerous social factors which shape the diagnosis, and in turn, provide a mechanism by which medicalisation can be enacted. Focussing on diagnostic classification provides an important perspective on the human condition and its relationship to medicine. To illustrate how layers of social meaning may be concealed in a diagnosis, this paper uses as heuristic the relatively obscure diagnosis of Female Hyposexual Desire Disorder which is currently surfacing in medical and marketing literature as a frequent disorder worthy of concern. I describe how this diagnosis embodies long-standing fascination with female libido, a contemporary focus on female hypersexuality, and commercial interest of the pharmaceutical industry and its medical allies to reify low sexual urge as a pathological disorder in women.

    This is a report on the research design and findings of a 23-year longitudinal study of the impact of intrafamilial sexual abuse on female development. The conceptual framework integrated concepts of psychological adjustment with theory regarding how psychobiological factors might impact development. Participants included 6- to 16-year-old females with substantiated sexual abuse and a demographically similar comparison group. A cross-sequential design was used and six assessments have taken place, with participants at median age 11 at the first assessment and median age 25 at the sixth assessment. Mothers of participants took part in the early assessments and offspring took part at the sixth assessment. Results of many analyses, both within circumscribed developmental stages and across development, indicated that sexually abused females (on average) showed deleterious sequelae across a host of biopsychosocial domains including: earlier onsets of puberty, cognitive deficits, depression, dissociative symptoms, maladaptive sexual development, hypothalamic–pituitary–adrenal attenuation, asymmetrical stress responses, high rates of obesity, more major illnesses and healthcare utilization, dropping out of high school, persistent psottraumatic stress disorder, self-mutilation, Diagnostic and Statistical Manual of Mental Disorders diagnoses, physical and sexual revictimization, premature deliveries, teen motherhood, drug and alcohol abuse, and domestic violence. Offspring born to abused mothers were at increased risk for child maltreatment and overall maldevelopment. There was also a pattern of considerable within group variability. Based on this complex network of findings, implications for optimal treatments are elucidated. Translational aspects of extending observational research into clinical practice are discussed in terms that will likely have a sustained impact on several major public health initiatives.

    Female sexual dysfunction (FSD) is a common problem that may be encountered in the interruption of normal sexual functioning in the sexual response cycle. Women with a pelvic floor disorder who scored low on the Female Sexual Function Index (FSFI) showed an improvement in their sexual life following treatment by vaginal electrical stimulation (VES). The aim of this trial was to evaluate the effectiveness of VES in women with FSD without a predominant pelvic floor disorder or urinary incontinence. Forty-two women with FSD were randomly allocated to VES and placebo groups. Pelvic floor muscle (PFM) assessment and the FSFI questionnaire were performed at baseline and after the completion of sessions. VES treatment was administered using a vaginal probe. The probe was inserted, and a medium-frequency (50 Hz) alternating current was administered for a duty cycle of 5 seconds on followed by a 5-second rest. Primary outcome measure was the improvement in FSFI score. PFM assessments were performed according to the PERFECT scheme. Total FSFI scores improved significantly in both the VES group and the control group. Results show that in the VES group, there was an improvement in total score and FSFI domains that improved including arousal, desire, orgasm, and satisfaction. Similarly, control group domains that improved were desire, arousal, and orgasm. But there was no significant increase in satisfaction scores in the placebo group. No significant changes in pain or lubrication domains were seen in either group. Power, endurance, fast contractions, and repetitions were significantly improved in the VES group. The lack of significant differences between the placebo and VES groups, except the satisfaction domain, puts into question the effectiveness of electrical stimulation as a monotherapy in treating primary FSD without pelvic floor disorder. © 2014 International Society for Sexual Medicine.

  11. Sexual cannibalism: high incidence in a natural population with benefits to females.

    Directory of Open Access Journals (Sweden)

    Rubén Rabaneda-Bueno

    Full Text Available BACKGROUND: Sexual cannibalism may be a form of extreme sexual conflict in which females benefit more from feeding on males than mating with them, and males avoid aggressive, cannibalistic females in order to increase net fitness. A thorough understanding of the adaptive significance of sexual cannibalism is hindered by our ignorance of its prevalence in nature. Furthermore, there are serious doubts about the food value of males, probably because most studies that attempt to document benefits of sexual cannibalism to the female have been conducted in the laboratory with non-natural alternative prey. Thus, to understand more fully the ecology and evolution of sexual cannibalism, field experiments are needed to document the prevalence of sexual cannibalism and its benefits to females. METHODOLOGY/PRINCIPAL FINDINGS: We conducted field experiments with the Mediterranean tarantula (Lycosa tarantula, a burrowing wolf spider, to address these issues. At natural rates of encounter with males, approximately a third of L. tarantula females cannibalized the male. The rate of sexual cannibalism increased with male availability, and females were more likely to kill and consume an approaching male if they had previously mated with another male. We show that females benefit from feeding on a male by breeding earlier, producing 30% more offspring per egg sac, and producing progeny of higher body condition. Offspring of sexually cannibalistic females dispersed earlier and were larger later in the season than spiderlings of non-cannibalistic females. CONCLUSIONS/SIGNIFICANCE: In nature a substantial fraction of female L. tarantula kill and consume approaching males instead of mating with them. This behaviour is more likely to occur if the female has mated previously. Cannibalistic females have higher rates of reproduction, and produce higher-quality offspring, than non-cannibalistic females. Our findings further suggest that female L. tarantula are nutrient

    Mammalian external genitals show sexual dimorphism [1, 2] and can change size and shape upon sexual arousal. Genitals feature prominently in the oldest pieces of figural art [3] and phallic depictions of penises informed psychoanalytic thought about sexuality [4, 5]. Despite this longstanding interest, the neural representations of genitals are still poorly understood [6]. In somatosensory cortex specifically, many studies did not detect any cortical representation of genitals [7-9]. Studies in humans debate whether genitals are represented displaced below the foot of the cortical body map [10-12] or whether they are represented somatotopically [13-15]. We wondered what a high-resolution mapping of genital representations might tell us about the sexual differentiation of the mammalian brain. We identified genital responses in rat somatosensory cortex in a region previously assigned as arm/leg cortex. Genital responses were more common in males than in females. Despite such response dimorphism, we observed a stunning anatomical monomorphism of cortical penis and clitoris input maps revealed by cytochrome-oxidase-staining of cortical layer 4. Genital representations were somatotopic and bilaterally symmetric, and their relative size increased markedly during puberty. Size, shape, and erect posture give the cortical penis representation a phallic appearance pointing to a role in sexually aroused states. Cortical genital neurons showed unusual multi-body-part responses and sexually dimorphic receptive fields. Specifically, genital neurons were co-activated by distant body regions, which are touched during mounting in the respective sex. Genital maps indicate a deep homology of penis and clitoris representations in line with a fundamentally bi-sexual layout [16] of the vertebrate brain.

    Fertilization is a central event in sexual reproduction, and understanding its molecular mechanisms has both basic and applicative biological importance. Recent studies have uncovered the molecules that mediate this process in a variety of organisms, making it intriguing to consider conservation and evolution of the mechanisms of sexual reproduction across phyla. The social amoeba Dictyostelium discoideum undergoes sexual maturation and forms gametes under dark and humid conditions. It exhibits three mating types, type-I, -II, and -III, for the heterothallic mating system. Based on proteome analyses of the gamete membranes, we detected expression of two homologs of the plant fertilization protein HAP2-GCS1. When their coding genes were disrupted in type-I and type-II strains, sexual potency was completely lost, whereas disruption in the type-III strain did not affect mating behavior, suggesting that the latter acts as female in complex organisms. Our results demonstrate the highly conserved function of HAP2-GCS1 in gamete interactions and suggest the presence of additional allo-recognition mechanisms in D. discoideum gametes.

    For almost 2000 years, human beings have been discussing about gender. New scientific evidences give interesting new points of view, partially subverting the normal dichotomy described by the "two-gender" theory. In this article, we are going to critically review the history of the approach towards people born with a Sexual-Differentiation-Disorder, passing through the analysis of the Italian National Ethics Committee's opinion, describing the modern scientific evidences on the gender-identity development, furthermore ruling out the new approach borned from the femminist philosophies, and the new biogiuridical experiments borned in Australia and Germany. Would it be possible a world where a person could be more then a male or a female?

    Assessment of sexual function is a complex process, especially in women, which requires in any individual case: time, appropriate training and experience. The prevalence of female sexual dysfunction is quite variable depending on the studied population, assessment methods, comorbid conditions and treatments, and age. A large number of screening methods have been developed over the last decades which range from tedious, exhaustive and boring tools to very simple standardized questionnaires. The 19-item female sexual function index (FSFI-19) is among the most used and useful- instrument designed to assess female sexual function in all types of circumstances, sexual orientation and perform the comparison of transcultural factors. A short 6-item- version of the FSFI-19 has been developed to provide a quick general approach to the six original domains (one item per domain). Nevertheless, further studies are needed to demonstrate its validity in different clinical situations as it has been extensively demonstrated with the original tool.

    2015-08-17

    Sexual harassment of women in medicine has become a subject of national debate after a senior female surgeon stated that if a woman complained of unwanted advances her career would be jeopardised, and subsequent reports suggest that sexual harassment is a serious problem in the medical profession. Sexual harassment of women in the medical profession by their colleagues presents substantial legal, ethical and cultural questions for the profession. Women have enforceable legal rights to gender equality and freedom from sexual harassment in the workplace. Both individual offenders and employers face significant legal consequences for sexual harassment in every Australian state and territory, and individual medical practitioners and employers need to understand their legal and ethical rights and responsibilities in this context. An individual offender may be personally liable for criminal offences, and for breaching anti-discrimination legislation, duties owed in civil law, professional standards and codes of conduct. An employer may be liable for breaching anti-discrimination legislation, workplace safety laws, duties owed in contract law, and a duty of care owed to the employee. Employers, professional colleges and associations, and regulators should use this national debate as an opportunity to improve gender equality and professional culture in medicine; individuals and employers have clear legal and ethical obligations to minimise sexual harassment to the greatest extent possible.

    Although female catarrhine primates show cyclic changes in sexual behavior and sexual swellings, the value of these sexual signals in providing information to males about timing of the fertile phase is largely unclear. Recently, we have shown that in Barbary macaques, males receive information from females which enables them to discern the fertile phase and to focus their reproductive effort accordingly. Here, we investigate the nature of the cues being used by examining female sexual behavior and the size of sexual swelling as potential indicators of the fertile phase. We collected behavioral data and quantified swelling size using digital images of 11 females of the Gibraltar Barbary macaque population and related the data to the time of ovulation and the fertile phase as determined from fecal hormone analysis. We found that rates of female sexual behaviors were not correlated with female estrogen levels and did not significantly differ between the fertile and non-fertile phases of the cycle. In contrast, swelling size was significantly correlated with female estrogen levels and increased predictably towards ovulation with size being maximal during the fertile phase. Moreover, frequencies of male ejaculatory copulations showed a strong positive correlation with swelling size and highest rates were found during maximum swelling. Our data provide strong evidence that female Barbary macaques honestly signal the probability of fertility through sexual swelling and that males apparently use this information to time their mating activities. Honest advertising of the fertile phase might be part of a female strategy to manipulate male mating behavior for their own advantage, such as ensure fertilization with high quality sperm or influence paternity outcome.

  4. Sexual Selection and the Male:Female Mortality Ratio

    Daniel J. Kruger

    2004-01-01

    Full Text Available This paper extends the evolutionary understanding of sex differences in mortality rates by quantifying and graphically examining the overall Male to Female Mortality Ratio (M:F MR for 11 specific leading causes of death across age groups in the USA, over the course of the lifespan in 20 different countries, and across the past 70 years in 5 countries. The resulting quantitative descriptions of rates, trends, and the relative contributions of various proximate causes of death to the M:F MR provide an initial exploration of the risks associated with being male. This analysis also illustrates how sex differences shaped by sexual selection interact in complex ways with multiple aspects of culture and environment to yield a pattern that has some consistency across decades and societies, but also has variations arising from differences among cohorts and cultures. The results confirmed our expectations of higher mortality rates for men than for women, especially in early adulthood, where three men died for every woman who died. For external causes the ratios were even higher. Historical mortality data reflect an epidemiological transition in which discrepancies between male and female mortality rates increase as general mortality rates fall. Cross-national variation in the modern M:F MR further suggests a universal pattern that is influenced by cultural and environmental context. Being male is now the single largest demographic risk factor for early mortality in developed countries.

    Individuals choose their mates so as to maximize reproductive success, and one important component of this choice is assessment of traits reflecting mate quality. Little is known about why specific traits are used for mate quality assessment nor about how they reflect it. We have previously shown that global manipulation of insulin signaling, a nutrient-sensing pathway governing investment in survival versus reproduction, affects female sexual attractiveness in the fruit fly, Drosophila melanogaster. Here we demonstrate that these effects on attractiveness derive from insulin signaling in the fat body and ovarian follicle cells, whose signals are integrated by pheromone-producing cells called oenocytes. Functional ovaries were required for global insulin signaling effects on attractiveness, and manipulations of insulin signaling specifically in late follicle cells recapitulated effects of global manipulations. Interestingly, modulation of insulin signaling in the fat body produced opposite effects on attractiveness, suggesting a competitive relationship with the ovary. Furthermore, all investigated tissue-specific insulin signaling manipulations that changed attractiveness also changed fecundity in the corresponding direction, pointing to insulin pathway activity as a reliable link between fecundity and attractiveness cues. The cues themselves, cuticular hydrocarbons, responded distinctly to fat body and follicle cell manipulations, indicating independent readouts of the pathway activity from these two tissues. Thus, here we describe a system in which female attractiveness results from an apparent connection between attractiveness cues and an organismal state of high fecundity, both of which are created by lowered insulin signaling in the fat body and increased insulin signaling in late follicle cells.

    Recent experiments have shown that sexual interactions prior to cell proliferation cause an increase in neurogenesis in adult male rats. Because adult neurogenesis is critical for some forms of memory, we hypothesized that sexually induced changes in neurogenesis may be involved in mate recognition. Sexually naive adult male rats were either exposed repeatedly to the same sexual partner (familiar group) or to a series of novel sexual partners (unfamiliar group), while control males never engaged in sexual interactions. Ovariectomized female rats were induced into estrus every four days. Males were given two injections of 5-bromo-2'-deoxyuridine (BrdU) (200mg/kg) to label proliferating cells, and the first sexual interactions occurred three days later. Males in the familiar and unfamiliar groups engaged in four, 30-min sexual interactions at four-day intervals, and brain tissue was collected the day after the last sexual interaction. Immunohistochemistry followed by microscopy was used to quantify BrdU-labeled cells. Sexual interactions with unfamiliar females caused a significant reduction in neurogenesis in the dentate gyrus compared to males that interacted with familiar females and compared to the control group. The familiar group showed no difference in neurogenesis compared to the control group. Males in the familiar group engaged in significantly more sexual behavior (ejaculations and intromissions) than did males in the unfamiliar group, suggesting that level of sexual activity may influence neurogenesis levels. In a second experiment, we tested whether this effect was unique to sexual interactions by replicating the entire procedure using anestrus females. We found that interactions with unfamiliar anestrus females reduced neurogenesis relative to the other groups, but this effect was not statistically significant. In combination, these results indicate that interactions with unfamiliar females reduce adult neurogenesis and the effect is stronger for sexual

    Understanding the role of socio-sexual cognitions and religiosity on adolescent sexual behavior could guide adolescent sexual health efforts. The present study utilized longitudinal data from 328 young women to assess the role of religion and socio-sexual cognitions on sexual behavior accrual (measuring both coital and non-coital sexual behavior). In the final triple conditional trajectory structural equation model, religiosity declined over time and then increased to baseline levels. Additionally, religiosity predicted decreased sexual conservatism and decreased sexual conservatism predicted increased sexual behavior. The final models are indicative of young women's increasing accrual of sexual experience, decreasing sexual conservatism and initial decreasing religiosity. The results of this study suggest that decreased religiosity affects the accrual of sexual experience through decreased sexual conservatism. Effective strategies of sexual health promotion should include an understanding of the complex role of socio-sexual attitudes with religiosity. PMID:24215966

    The water flea Daphnia are planktonic crustaceans commonly found in freshwater environment that can switch their reproduction mode from parthenogenesis to sexual reproduction to adapt to the external environment. As such, Daphnia are great model organisms to study the mechanism of reproductive switching, the underlying mechanism of reproduction and development in cladocerans and other animals. However, little is known about the Daphnia’s reproductive behaviour at a molecular level. We constructed a genetic database of the genes expressed in a sexual female (SF) and a parthenogenetic female (PF) of D. similoides using Illumina HiSeq 2500. A total of 1,763 differentially expressed genes (865 up- and 898 down-regulated) were detected in SF. Of the top 30 up-regulated SF unigenes, the top 4 unigenes belonged to the Chitin_bind_4 family. In contrast, of the top down-regulated SF unigenes, the top 3 unigenes belonged to the Vitellogenin_N family. This is the first study to indicate genes that may have a crucial role in reproductive switching of D. similoides, which could be used as candidate genes for further functional studies. Thus, this study provides a rich resource for investigation and elucidation of reproductive switching in D. similoides. PMID:27671106

    We explored the role that sexual and social partners play in the expression of female homosexual behavior among adolescent female Japanese macaques at Arashiyama, Japan. Our data fully or partially supported all the predictions related to four non-mutually exclusive hypotheses, namely the "adult male disinterest in adolescent females" hypothesis, the "numerous homosexual adult females" hypothesis, the "safer homosexual interactions" hypothesis and the "same-sex sexual interactions" hypothesis. Our results show that both sexual context (e.g., lack of adolescent female attractivity toward adult males, presence of motivated same-sex sexual partners), and social context (e.g., risk of aggression) help explain the high frequency and prevalence of homosexual behavior in adolescent females in the Arashiyama group of Japanese macaques. As with adult females, whose homosexual consortships do not reflect generalized patterns of social affiliation or kinship, we found that adolescent females' same-sex sexual partners were neither kin, nor were they non-kin individuals with whom adolescent females were closely affiliated outside of a consortship context. Our study furthers the growing database of female homosexual behavior in Japanese macaques and provides additional evidence that homosexual behavior as expressed by adolescent female Japanese macaques is, like heterosexual behavior, sexual in nature. We discuss the relevance of our findings to a broader comparative approach that may shed light upon the development and evolution of human homosexuality.

    This paper presents the findings of a cross-sectional survey on the risk and protective factors of premarital sexual behavior among rural female adolescents in Peninsular Malaysia. We investigated data on 770 female respondents aged 13-17 years in rural areas to identify predictive factors for premarital sexual intercourse. Data were analyzed using bivariate and multivariate regression. Specific socio-demographic factors, psychological and family domains, peer delinquency, and knowledge and attitudes about sexuality were considered in risky sexual behaviors in rural Malay girls. The effects of other covariates for premarital sexual intercourse were controlled by logistic regression model. Of the 770 rural female students, about 3.2% of respondents reported experience of sexual intercourse in the past three months. Out of those sexually active girls, 36% were 17 years old and 20% stated having sexual intercourse with more than one partner, and 72% did not use contraception during the most recent sexual intercourse. Midnight activities, peer-sexual disorder, self-evaluation, and attitude toward sexual health were significant predictors of sexual intercourse in rural girls in Malaysia. The finding highlights the impact of psychological factors and peer group influences on the challenges of premarital sexual behavior among rural girls and the notion of school-based sexual health education for adolescents. This study triggers other researchers take into account a comprehensive view of protective factors operating in adolescents' risky sexual behaviors in Asian culture seeing that family domain variables, unexpectedly, exerted no predicting influence on sexually active female teens in rural areas in Malaysia.

    2012-02-01

    Sexual harassment is a common outcome of sexual conflict over mating rate. A large number of studies have identified several direct costs to females of sexual harassment including energy expenditure and reduced foraging ability. However, the fitness consequences of sexual harassment for descendants have rarely been investigated. Here, we manipulated the level of sexual harassment and mating rate in two groups of female guppies, Poecilia reticulata, a live-bearing fish in which sexual conflict over mating rate is particularly pronounced. Each female was allowed to interact with three males for one day (low sexual harassment, LSH) or for eight days (high sexual harassment, HSH) during each breeding cycle throughout their life. Female lifetime fecundity did not differ between the groups, but we found a strong effect on offspring fitness. HSH females produced (1) daughters with smaller bodies and (2) sons with shorter gonopodia, which were less attractive to females and less successful in coercive matings than their LSH counterparts. Although these results may be influenced by the indirect effects of sex ratio differences between treatments, they suggest that sexual harassment and elevated mating rate can have negative cross-generational fitness effects and more profound evolutionary consequences than currently thought.

    Visual information about face and body including facial expression and bodily behavioral patterns has been known to play an important role in social and emotional communication in monkeys. Its involvement in sexual activity has also been demonstrated in male monkeys but it is poorly understood in female monkeys. In the present study, visually-guided discrimination and preference of sexuality were investigated in female macaque monkeys performing operant bar-press tasks in an experimental cage which had a transparent panel facing a display. In the sex discrimination task, two rhesus monkeys (Macaca mulatta) were trained to discriminate sex of a monkey shown in a picture which was randomly selected from six photographs (three males and three females) and was presented on the display. The monkey pressed a right or left bar for male or female monkey, respectively, to get water as a reward. Under this discrimination task, the monkeys could discriminate the sexes of monkeys shown in newly presented pictures. When choice bars were reversed, correct responses significantly decreased below chance level. In the sex preference task, three rhesus monkeys and three Japanese monkeys (M. juscata) were used. The monkeys voluntarily pressed the bar to watch the video movie showing either male or female rhesus monkeys. The movies were presented as long as the subject kept pressing the bar. The same movie was continued when the monkey pressed the bar again within 10s after the previous release of the bar, while it was changed to the other when 10s passed after the subject released the bar. The total duration of the responses in daily sessions was measured. In this visual preference task, four out of six monkeys showed sex preference. Three adult Japanese monkeys (6-8 y) pressed the bar to watch the video movie of male monkeys which was taken in breeding season with longer duration than that of female monkeys taken in the same season. The other two adult rhesus monkeys (7 8 y) did not

    In many cercopithecine primates females display probabilistic cues of fertility to indicate the periovulatory period to males. These cues may include female behaviour, acoustic signals, and morphological signs such as the anogenital swelling. However, the extent to which males can utilise this information varies between species. We describe male sexual behaviour in relation to changes in anogenital swelling size, timing of ovulation and female socio-sexual behaviour in wild Barbary macaques (Macaca sylvanus). We further compare male sexual behaviour during conception and post-conception cycles to evaluate if males differentiate between these qualitatively different cycle types. Our results show that during conception cycles male mating behaviour was concentrated around the fertile phase implying that males inferred information from more than swelling size alone. Male mating frequency increased in line with female socio-sexual behaviour, namely female presenting and the frequency of copulations with copulation calls. Most strikingly our results show that males invested equally in mating during fertile and non-fertile, i.e. post-conception, maximum swelling phases. Whether post-conception swellings were merely a result of changes in hormone concentrations during pregnancy or part of a female reproductive strategy remains elusive. In sum, this study adds to the body of research on the evolution of female sexual signals and how males may infer information from these cues.

    Full Text Available Background Opiate abuse in males has significant effects on their sexual functions. In contrast, sexuality in females is a multidimensional issue that can strongly be affected by several factors in their partners. However, only a limited number of studies have assessed the role of males’ opioid dependency in their female partners’ sexual function. Objectives The present study aimed to evaluate the effect of males’ opioid dependency on their wives’ sexual function compared to the sexual function of the females whose husbands were not opioid dependent. Patients and Methods This study included 340 women who were selected through convenience sampling and divided into a control (females whose husbands were not opioid dependent and a case group (women whose husbands were opioid dependent. The data were collected through an interview according to the DSM-IV-R criteria for female sexual dysfunctions by a senior female medical student who was one of the researchers. Finally, the data were entered into the SPSS statistical software (v. 15 and analyzed using the t-test and chi-square test. Results According to the results, the frequency of hypoactive sexual desire disorder and sexual aversion disorder in the control group was significantly higher than that of the case group (P < 0.05. Conclusions The results showed that having an addicted husband could strongly affect some sexual domains in women. It could change the pattern of desire and motivation for sexual contact in females and alter their attitude toward the sexual relationship, thereby causing disturbances in the females’ normal sexual function.

    2001-08-01

    Variation among females in mate choice may influence evolution by sexual selection. The genetic basis of this variation is of interest because the elaboration of mating preferences requires additive genetic variation in these traits. Here we measure the repeatability and heritability of two components of female choosiness (responsiveness and discrimination) and of female preference functions for the multiple ornaments borne by male guppies (Poecilia reticulata). We show that there is significant repeatable variation in both components of choosiness and in some preference functions but not in others. There appear to be several male ornaments that females find uniformly attractive and others for which females differ in preference. One consequence is that there is no universally attractive male phenotype. Only responsiveness shows significant additive genetic variation. Variation in responsiveness appears to mask variation in discrimination and some preference functions and may be the most biologically relevant source of phenotypic and genetic variation in mate-choice behavior. To test the potential evolutionary importance of the phenotypic variation in mate choice that we report, we estimated the opportunity for and the intensity of sexual selection under models of mate choice that excluded and that incorporated individual female variation. We then compared these estimates with estimates based on measured mating success. Incorporating individual variation in mate choice generally did not predict the outcome of sexual selection any better than models that ignored such variation.

    Sex-type in Drosophila melanogaster is controlled by a hierarchically acting set of regulatory genes. At the terminus of this hierarchy lie those regulatory genes responsible for implementing sexual differentiation: genes that control the activity of target loci whose products give rise to sexually dimorphic phenotypes. The genetic analysis of the intersex (ix) gene presented here demonstrates that ix is such a terminally positioned regulatory locus. The ix locus has been localized to the cytogenetic interval between 47E3-6 and 47F11-18. A comparison of the morphological and behavioral phenotypes of homozygotes and hemizygotes for three point mutations at ix indicates that the null phenotypes of homozygotes diplo-X animals into intersexes while leaving haplo-X animals unaffected. Analysis of X-ray induced, mitotic recombination clones lacking ix{sup +} function in the abdomen of diplo-X individuals indicates that the ix{sup +} product functions in a cell-autonomous manner and that it is required at least until the termination of cell division in this tissue. Taken together with previous analyses, our results indicate that the ix{sup +} product is required to function with the female-specific product of doublesex to implement appropriate female sexual differentiation in diplo-X animals. 55 refs., 4 figs., 4 tabs.

    Selection clearly focuses on differences in reproduction, but studies of reproductive physiology generally have been carried out in a near vacuum of modern evolutionary theory. This lack of contact between the two fields may be about to change. New ideas indicate that sexual selection by cryptic female choice has affected the evolution of products in male semen that influence female reproductive behavior and physiology.

    2001-08-01

    Sexual activity among 534 Nigerian female secondary school students was studied using self-administered questionnaire. Prevalence of sexual intercourse was 25.7%. There was no significant difference between the junior (48.2%) and senior (51.8%) students (p > 0.05). Seventeen (12.4%) students had initiated sexual intercourse before 11 years. The frequency of sexual exposure was high, with 34.3% of the students having intercourse more than once in a week. Pregnancy rate among sexually active females was 27.0%, with 24.8% rate of induced abortion. Early sexual health education starting from primary school would be helpful in influencing the reproductive decisions and sexual behaviour of the students, including contraceptive acceptance and usage, to avoid teenage pregnancy. Education of parents is also recommended in order to overcome the cultural barriers that discourage parents from providing sex education to their children at home.

  6. What motivates the sexual double standard? More support for male versus female control theory.

    The present research uniquely compared male control theory (MCT) versus female control theory (FCT) to illuminate motives for the sexual double standard (SDS), whereby men gain status from engaging in casual sex or having many sexual partners, but women are stigmatized for it. Consistent with MCT, men were more likely than women to endorse the SDS and to give sexual advice in ways that reinforce it-gender differences that were mediated by hostile sexism (HS) and endorsing the SDS, respectively. The data did not support FCT's argument that women are motivated by sexual economics to restrict female sexuality (Baumeister & Twenge, 2002). Both genders discouraged women from having casual sex to protect women from social stigma and rape myths that justify violence against sexual women. In concert, the findings support MCT more than FCT and suggest that sexism, stigma, and rape myths are primary obstacles to sexual equality.

  7. Tissue-specific insulin signaling mediates female sexual attractiveness.

    Full Text Available Individuals choose their mates so as to maximize reproductive success, and one important component of this choice is assessment of traits reflecting mate quality. Little is known about why specific traits are used for mate quality assessment nor about how they reflect it. We have previously shown that global manipulation of insulin signaling, a nutrient-sensing pathway governing investment in survival versus reproduction, affects female sexual attractiveness in the fruit fly, Drosophila melanogaster. Here we demonstrate that these effects on attractiveness derive from insulin signaling in the fat body and ovarian follicle cells, whose signals are integrated by pheromone-producing cells called oenocytes. Functional ovaries were required for global insulin signaling effects on attractiveness, and manipulations of insulin signaling specifically in late follicle cells recapitulated effects of global manipulations. Interestingly, modulation of insulin signaling in the fat body produced opposite effects on attractiveness, suggesting a competitive relationship with the ovary. Furthermore, all investigated tissue-specific insulin signaling manipulations that changed attractiveness also changed fecundity in the corresponding direction, pointing to insulin pathway activity as a reliable link between fecundity and attractiveness cues. The cues themselves, cuticular hydrocarbons, responded distinctly to fat body and follicle cell manipulations, indicating independent readouts of the pathway activity from these two tissues. Thus, here we describe a system in which female attractiveness results from an apparent connection between attractiveness cues and an organismal state of high fecundity, both of which are created by lowered insulin signaling in the fat body and increased insulin signaling in late follicle cells.

    The process of bringing new drugs to market interweaves commercialism, science, clinical medicine, and governmental regulation. Through their authority and public persona as medical experts, academic clinical trial researchers studying these pharmaceuticals are integral to this process, serving as mediators between producers (the pharmaceutical companies) and consumers (clinicians and patients) of new drugs through a complex set of exchange networks. Using examples from my ethnographic research on the search for pharmaceuticals to treat what has become known as female sexual dysfunction, this paper explores the links academic researchers make with drug manufacturers and consumer markets. Academic researchers have become an integral aspect of drug development, not only by conducting clinical trial research, but also by participating in a number of other activities that assist pharmaceutical companies in identifying and creating new markets. In this paper, i examine how researchers attend professional meetings where they present clinical trial data, lecture at continuing medical education conferences, and offer themselves as ' experts' to raise awareness about disorders and their treatments. Modifying a sociology of technology approach, this paper focuses on the actors in the social network who mediate the junctions between technological producers and consumers. This extends work in this area through theorizing the linkages between exchange networks, commodification techniques, and technoscientific developments.

    The objective of this study was to examine the risk of female sexual orgasmic disorder among a group of women with hypertension in Malaysia. The associated factors were also examined. This cross-sectional study involved 348 hypertensive women attending the primary care or hypertension clinic in a teaching hospital in Malaysia. Female sexual orgasmic disorder was assessed using the Orgasmic subscale of the Malay Version of the Female Sexual Function Index (MVFSFI). Basic socio-demographic data of the subjects was collected using a predesigned questionnaire. Medical records were reviewed to gather patients' medical information. The risk of female sexual orgasmic disorder among hypertensive women was 14.1%. Univariate analysis found that older age, longer duration of marriage, lower educational level, and menopause were associated with higher risk of female sexual orgasmic disorder. These factors were not significant in multivariate analysis. The risk of female sexual orgasmic disorder was relatively low in Malaysian women with hypertension. No risk factors were associated with female sexual orgasmic disorder in the current study. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

    Nosenko, N D; Lymarieva, A A

    2013-01-01

    The parameters of female and male sexual behavior in 3- and 6- month old female rats which were exposed to an androgen excess (subcutaneous implantation of Silastic capsules containing 5 mg of crystalline testosterone) from the beginning of pubertal period (at the age of 35 days), or within postpubertal period (at the age of 4 months). Hyperandrogenia in pubertal period had no effect on female sexual behavior formation, but it led to appearance of male behavior components in 100% of animals. In female rats which were implanted with testosterone capsules in postpubertal period, sexual disturbances were more pronounced and were characterized by masculinization and defeminization, which was due to a higher degree of androgenic saturation. The data obtained suggest a leading role of hyperandrogenemia in the pathogenesis of sexual behavior disturbances in female rats in different periods of individual development.

  11. A selective androgen receptor modulator enhances male-directed sexual preference, proceptive behavior, and lordosis behavior in sexually experienced, but not sexually naive, female rats.

    Androgens influence many aspects of reproductive behavior, including sexual preference of females for males. In oophorectomized women with sexual desire disorder, testosterone patches improve libido, but their use is limited because of adverse side effects. Selective androgen receptor modulators offer an improved safety profile for both sexes: enhancing libido and muscle and bone growth in a manner similar to steroidal androgens but with fewer adverse effects, such as hirsutism, acne, and prostate growth. The current study investigated the action of a novel selective androgen receptor modulator (LGD-3303 [9-chloro-2-ethyl-1-methyl-3-(2,2,2-trifluoroethyl)-3H-pyrrolo-[3,2-f]quinolin-7(6H)-one]) on male-directed sexual preference, proceptivity, and lordosis behavior of female rats. LGD-3303 is a nonsteroidal, nonaromatizable, highly selective ligand for the androgen receptor and effectively crosses the blood-brain barrier. Gonadectomized female rats were treated with LGD-3303 (3-30 mg/kg) or vehicle by daily oral gavage. Results showed that LGD-3303 treatment enhanced sexual preference of females for males but only if females had previous sexual experience. This occurred after 1 or 7 d of treatment. In contrast, preference for males was inhibited by LGD-3303 treatments of sexually naive females. The LGD-3303 increase in male preference was blocked by pretreatment with the androgen receptor antagonist flutamide. LGD-3303 treatment increased lordosis and proceptivity behaviors in ovariectomized females primed with suboptimal doses of estradiol benzoate plus progesterone. These data support the concept that LGD-3303 can stimulate aspects of female sexual behavior and may serve as a potential therapeutic for women with sexual desire disorders.

  12. Attachment and personality predicts engagement in sexual harassment by male and female college students.

    2010-01-01

    The purpose of this study was to examine a trait model of personality (Five-Factor Model) as a mediator of the relationship between attachment styles and sexually harassing behavior in a sample of male (N = 148) and female (N = 278) college students. We found that gender (male) and low Agreeableness predicted engaging in sexual harassment and all three of its subtypes; gender harassment, unwanted sexual attention, and sexual coercion. Further, low Conscientiousness predicted overall sexual harassment, gender harassment, and unwanted sexual attention. Personality traits mediated the relationship between insecure attachment styles (Preoccupation with Relationships and Relationships as Secondary) and sexually harassing behaviors. Thus, factors beyond gender can help predict students' propensity to sexually harass others.

  13. The construct of sexual openness for females in steady intimate relationships

    The analysis of open-minded attitudes towards sexuality in general requires a construct based on attitudinal dimensions. Although several existing studies involve sexual attitudes, they differ substantially and standardized conceptual work is missing. Thus, the authors introduce the latent variable sexual openness to develop a construct based on self-oriented attitudes towards different sexual topics. Available survey data of female German students in a steady relationship allowed providing a first empirical test for the applicability of this construct. Five subdimensions are acknowledged central for sexual openness: sexual practices, masturbation, bisexuality, permissiveness, and pornography consumption. Confirmatory factor analysis and correlations confirmed the idea of an underlying mechanism with an impact on all five variables. Though further validation of the construct of sexual openness is required, the findings strongly support the notion of an overarching latent attitude variable, which influences the individual relation to everything sexual. The results were compared to other studies and potential approaches for future analyses were proposed. PMID:28636608

    2007-08-01

    In this paper, we aim at demonstrating individual recognition of female genital marking in Lemur catta. By gas chromatography and behavioural trials we verified the occurrence of the three components of recognition systems. We showed that each female has a unique chemical signature (expression component), and males and females perceive female individuality (perception component). To verify the presence of the action component (the last component of recognition systems), we designed a bioassay based on territorial competition to verify the functional response to female odours. Only females identified other females on the basis of their scents. The lack of a territorial functional response by males to female secretions may not indicate a male inability to identify females by their scents. In fact, sexual dimorphism in motivation and territorial defence may explain the response by males in the functional experiment. Actually, game theory predicts that males defend their own territories more vigorously against males compared with females. Therefore, the result of individual recognition bioassays of female odours may open interesting scenarios in the evaluation of the territorial defence investment across the different sex combinations.

    Alcohol use has been linked to risky sexual practices among adolescents. However, limited research on alcohol use and risky sexual behavior has been conducted among female adolescents. This study examined a high quantity of alcohol as a longitudinal predictor of risky sexual behavior and sexually transmitted diseases (STDs) among female adolescents. Three hundred ninety-three adolescent females aged 15-21 were assessed for alcohol use and risky sexual behaviors. Participants also provided 2 swab specimens that were assayed for STDs. Use of high alcohol quantity was defined as > or = 3 drinks in 1 sitting. Binary generalized estimating equation models were conducted assessing the impact of alcohol use at baseline on risky sexual behavior and STDs over a 12-month period. Age, intervention group and baseline outcome measures were entered as covariates. The results indicated that use of high alcohol quantity predicted inconsistent condom use, high sexual sensation seeking, multiple sexual partners, sex while high on alcohol or drugs, and having anal sex during 12-month follow-up period. These findings suggest that STD-related behavioral interventions for adolescents should discuss the link between alcohol and STD-risk behavior. Deeper understanding of alcohol as a predictor of risky sexual behavior among female adolescents is of paramount importance for development of efficient prevention programs at individual and community levels. The risk of acquiring an STD is higher among teenagers than among adults.

    This study examines whether sexually transmitted infection prevention knowledge predicts the acquisition of biologically confirmed sexually transmitted infections among African-American adolescent females. A total of 715 females were recruited from public health clinics in Atlanta, Georgia, and using audio computer-assisted self-interview technology, we assessed for demographics, sexually transmitted infection prevention knowledge, risky sexual behaviors, and sexually transmitted infections. After controlling for demographics and prior risky sexual behaviors, participants with high prevention knowledge were 0.09 times less likely to report sexually transmitted infections, and those with multiple sexual partners were 1.3 times more likely to report sexually transmitted infections. Our findings suggest that the promotion of accurate sexually transmitted prevention knowledge is critical especially among females with multiple sex partners.

    Female sexual dysfunction (FSD) is defined as disturbances in sexual desire and the psychophysiological changes that characterize the sexual response cycle, which cause marked distress and interpersonal difficulty. Female sexual dysfunction is strongly related to socio-cultural characteristics of a certain region and can change over time. Authors previously reported the features of FSD in Korea through an analysis of an internet-based survey conducted in 2004. This time, we designed a 10-year interval study to compare the prevalence of and risk factors of FSD through the Korean Internet Sexuality Survey (KISS) 2014. The internet-based survey was targeted towards 20-59-year-old women, who were asked to answer the questionnaire only if they were sexually active. In total, 516 responses were analyzed and the mean age of the subjects was 38.1±10.3 years. We defined FSD as having a total FSFI score of under 25.0, and resulted in a prevalence of FSD of 46.7%. The prevalence of FSD in each age group increased with age from 23.7, 45.4, 51.4 to 72%, for those in their 20, 30, 40 and 50s, respectively. Among the 50s age group, lubrication and pain domain dysfunctions were highly prevalent. The risk factors for FSD were identified as constipation, depression, incontinence, age of first intercourse, number of sexual partners and the use of oral contraceptive pills. Although the some demographic features of this study was different with those of the 2004 repot, the prevalence of FSD was similar with that reported previously in 2004 and a few risk factors of FSD was consistently significant in these interval studies.International Journal of Impotence Research advance online publication, 8 December 2016; doi:10.1038/ijir.2016.41.

    2017-06-01

    Combined oral contraceptive pills (COCs) remain one of the most popular forms of contraception to prevent unwanted pregnancy in women. While it is known that COCs can cause sexual dysfunction in women, there is currently no recommendation to screen for sexual function before and after initiation of COCs. We propose that, based on the evidence available, assessment of sexual function should be done at initiation of COCs, as well as at regular intervals thereafter. This would allow COC-related sexual dysfunction to be managed early, such as by switching the patient to newer-generation COCs or other forms of contraception.

    2016-03-16

    Hypoactive sexual desire disorder (HSDD) is a deficiency of sexual desire that causes marked personal or interpersonal distress. It occurs in approximately 1 in 10 adult women. A number of potential contributory factors (hormonal, neurobiological and psychosocial) have been identified. Testosterone plays an excitatory role in sexual desire but the mechanism is not yet well understood. Treatment with testosterone has been shown to improve sexual desire in menopausal women with HSDD. However, there are limited data concerning premenopausal women and long-term safety. At present, physiological testosterone preparations for use in women are not available in Switzerland.

  3. Acceptance of Treatment of Sexually Transmitted Infections for Stable Sexual Partners by Female Sex Workers in Kampala, Uganda.

    Full Text Available The prevalence of sexually transmitted infections (STIs among female sex workers (FSWs in sub-Saharan Africa remains high. Providing treatment to the affected FSWs is a challenge, and more so to their stable sexual partners. There is scanty research information on acceptance of STI treatment for stable sexual partners by FSWs. We conducted a study to assess acceptance of STI treatment for stable sexual partners by FSWs, and to identify factors associated with acceptance.We enrolled 241 FSWs in a cross sectional study; they were aged ≥ 18 years, had a stable sexual partner and a diagnosis of STI. Factors associated with acceptance of STI treatment for stable sexual partners were analysed in STATA (12 using Poisson regression. Mantel-Haenszel tests for interaction were performed.Acceptance of partner treatment was 50.6%. Majority (83.8% of partners at the last sexual act were stable partners, and 32.4% of participants had asymptomatic STIs. Factors independently associated with acceptance were: earning ≤ $4 USD per sexual act (aPR 0.68; 95% CI: 0.49-0.94 and a clinical STI diagnosis (aPR 1.95; 95% CI: 1.30-2.92. The effect of low income on acceptance of partner treatment was seen in those with less education.Acceptance of STI treatment for stable sexual partners was lower than that seen in other studies. Interventions to improve economic empowerment among FSWs may increase acceptance of partner treatment.

    This multi-center, randomized, placebo-controlled, crossover design study evaluated the effects of a topical alprostadil solution for the treatment of female sexual arousal disorder (FSAD). A total of 79 naturally or surgically post menopausal women with FSAD were treated with either 100 or 400 micrograms of alprostadil solution and placebo, delivered on separate clinic visits in random order. Study drug was applied to the external genitalia and was followed by 30 minutes of visual sexual stimulation. Study evaluations included investigator assessments of genital vasocongestion and patient assessments of physical and emotional sexual arousal, and sexual satisfaction. Genital vasocongestion in response to PGE1 was significantly greater than placebo (p alprostadil. Topical alprostadil was well tolerated with no reports of significant systemic side effects. The most common adverse event was mild, transient genital burning typically alprostadil should be further researched as a potentially appropriate on-demand therapeutic choice for women experiencing FSAD.

  5. Sexual conflict and the evolution of female mate choice and male social dominance.

    2001-03-07

    Conflicts between the sexes over control of reproduction are thought to lead to a cost of sexual selection through the evolution of male traits that manipulate female reproductive physiology and behaviour, and female traits that resist this manipulation. Although studies have begun to document negative fitness effects of sexual conflict, studies showing the expected association between sexual conflict and the specific behavioural mechanisms of sexual selection are lacking. Here we experimentally manipulated the opportunity for sexual conflict in the cockroach. Nauphoeta cinerea and showed that, for this species, odour cues in the social environment influence the behavioural strategies and fitness of males and females during sexual selection. Females provided with the opportunity for discriminating between males but not necessarily mating with preferred males produced fewer male offspring than females mated at random. The number of female offspring produced was not affected, nor was the viability of the offspring. Experimental modification of the composition of the males' pheromone showed that the fecundity effects were caused by exposure to the pheromone component that makes males attractive to females but also makes males less likely to be dominant. Female mate choice therefore carries a demographic cost but functions to avoid male manipulation and aggression. Male-male competition appears to function to circumvent mate choice rather than directly manipulating females, as the mate choice can be cryptic. The dynamic struggle between the sexes for control of mating opportunities and outcomes in N. cinerea therefore reveals a unique role for sexual conflict in the evolution of the behavioural components of sexual selection.

  6. Escalation, retreat, and female indifference as alternative outcomes of sexually antagonistic coevolution.

    Rowe, Locke; Cameron, Erin; Day, Troy

    2005-05-01

    Verbal and quantitative genetic models of sexually antagonistic coevolution suggest that coevolutionary arms races should be common. Sexual selection favors exaggeration of male persistence traits that are costly to females, and females, in turn, are selected to resist these traits. The heightened resistance by females is thought to then favor further exaggeration in the male trait, leading to an escalating coevolutionary arms race between persistence and resistance traits. Much of this theory, however, is based on an (implicit) assumption that there are tight constraints on how female resistance can evolve. We develop a theory that identifies and relaxes these constraints, allowing female resistance to evolve in a fashion that better reflects known empirical patterns in the evolution of female preference functions (the resistance trait). Our results suggest that evolutionary arms races that lead to the exaggeration of persistence and resistance will be much less common than formerly predicted. Females sometimes evolve indifference to male traits rather than resistance and can even evolve to discriminate against these traits. These alternative outcomes depend on the existence of genetic variance in the components of the female sensory system underlying female resistance and on the strength of natural selection acting on these components. Female indifference tends to evolve when natural selection on the sensory system is weak, and under these conditions, sexually antagonistic coevolution tends not to reduce female fitness significantly at equilibrium. When natural selection on the female sensory system is strong, however, then arms races are more likely, and female fitness is then sometimes significantly depressed at equilibrium. Sexually antagonistic coevolution is thus likely to have strong deleterious effects on population fitness only when female sensory traits are under strong natural selection to perform functions in addition to those involved with mating

    Many species use social networks to buffer the effects of stress. The mere absence of a social network, however, may also be stressful. We examined neuroendocrine, PVN CRH neurons and report that social isolation alters the intrinsic properties of these cells in sexually dimorphic fashion. Specifically, isolating preadolescent female mice from littermates for neurons. These changes were not evident in age-matched males. By contrast, subjecting either males (isolated or grouped) or group housed females to acute physical stress (swim), increased FSL. The increase in FSL following either social isolation or acute physical stress was blocked by the glucocorticoid synthesis inhibitor, metyrapone and mimicked by exogenous corticosterone. The increase in FSL results in a decrease in the excitability of CRH neurons. Our observations demonstrate that social isolation, but not acute physical stress has sex-specific effects on PVN CRH neurons. DOI: http://dx.doi.org/10.7554/eLife.18726.001 PMID:27725087

    Research indicates gender differences in sensitivity to psychomotor stimulants. Preclinical work investigating the interaction between drugs of abuse and sex-specific behaviors, such as sexual behavior, is critical to our understanding of such gender differences in humans. A number of behavioral paradigms can be used to model aspects of human sexual behavior in animal subjects. Although traditional assessment of the reflexive, lordosis posture of the female rat has been used to map the neuroanatomical and neurochemical systems that contribute to uniquely female copulatory behavior, the additional behavioral paradigms discussed in the current review have helped us expand our description of the appetitive and consummatory patterns of sexual behavior in the female rat. Measuring appetitive behavior is particularly important for assessing sexual motivation, the equivalent of "desire" in humans. By investigating the effects of commonly abused drugs on female sexual motivation, we are beginning to elucidate the role of dopaminergic neurotransmission, a neural system also known to be critical to the neurobiology of drug addiction, in female sexual motivation. A better understanding of the nexus of sex and drugs in the female brain will help advance our understanding of motivation in general and explain how psychomotor stimulants affect males and females differently.

  9. Female sexual advertisement reflects resource availability in twentieth-century UK society.

    Evolutionary theory suggests that men and women differ in the characteristics valued in potential mates. In humans, males show a preference for physical attractiveness, whereas females seek cues that relate to resources and future earning potential. If women pursue marriage as an economic strategy, female sexual advertisement should increase during periods of poor economic conditions when the number of high-quality male partners becomes a limited resource. To test this prediction, measures of skin display and clothing tightness were taken for clothes portrayed in UK Vogue magazine from 1916 to 1999. These estimates of sexual advertisement were analyzed in relation to an index of economic prosperity (GDP), while controlling for general increases in economic conditions and sexual display over the course of the past century. The results indicate that female sexual display increases as economic conditions decline, with the level of breast display and the tightness of clothing at the waist and hips the key factors underlying this increase. Breast size and symmetry and female body form are secondary sexual characteristics that play an important role in sexual attractiveness. Since advertisement of these features increases as levels of competition for high-quality partners increases, females appear to use marriage as an economic strategy. Patterns of female fashion appear to be underpinned by evolutionary considerations relating resource availability to female reproductive success.

  10. Cloacal bacterial diversity increases with multiple mates: evidence of sexual transmission in female common lizards.

    Directory of Open Access Journals (Sweden)

    Joël White

    Full Text Available Sexually transmitted diseases have often been suggested as a potential cost of multiple mating and as playing a major role in the evolution of mating systems. Yet there is little empirical data relating mating strategies to sexually transmitted microorganisms in wild populations. We investigated whether mating behaviour influences the diversity and composition of cloacal assemblages by comparing bacterial communities in the cloaca of monandrous and polyandrous female common lizards Zootoca vivipara sampled after the mating period. We found that polyandrous females harboured more diverse communities and differed more in community composition than did monandrous females. Furthermore, cloacal diversity and variability were found to decrease with age in polyandrous females. Our results suggest that the higher bacterial diversity found in polyandrous females is due to the sexual transmission of bacteria by multiple mates. The impact of mating behaviour on the cloacal microbiota may have fitness consequences for females and may comprise a selective pressure shaping the evolution of mating systems.

    Objective to assess Female Sexual Function Index (FSFI) scores and delay to resume sexual activity associated with a previous severe maternal morbidity. Method This was a multidimensional retrospective cohort study. Women who gave birth at a Brazilian tertiary maternity between 2008 and 2012 were included, with data extraction from the hospital information system. Those with potentially life-threatening conditions and maternal near miss episodes (severe maternal morbidity) were considered the exposed group. The control group was a random sample of women who had had uncomplicated pregnancy. Female sexual function was evaluated through FSFI questionnaire, and general and reproductive aspects were addressed through specific questions. Statistical analyses were performed using Mann-Whitney and Pearson´s Chi-square for bivariate analyses. Logistic regression was used to identify variables independently associated with lower FSFI scores. Results 638 women were included (315 at exposed and 323 at not exposed groups). The majority of women were under 30 years-old in the control group and between 30 and 46 years-old in the exposed group (p = 0.003). Women who experienced severe maternal morbidity (SMM) had statistically significant differences regarding cesarean section (82.4% versus 47.1% among deliveries without complications, p<0.001), and some previous pathological conditions. FSFI mean scores were similar among groups ranging from 24.39 to 24.42. It took longer for exposed women to resume sexual activity after index pregnancy (mean 84 days after SMM and 65 days for control group, p = 0.01). Multiple analyses showed no significant association of FSFI below cut-off value with any predictor. Conclusion FSFI scores were not different in both groups. However, they were lower than expected. SMM delayed resumption of sexual activity after delivery, beyond postpartum period. However, the proportion of women in both groups having sex at 3 months after delivery was similar

    Understanding the role of socio-sexual cognitions and religiosity on adolescent sexual behavior could guide adolescent sexual health efforts. The present study utilized longitudinal data from 328 young women to assess the role of religion and socio-sexual cognitions on sexual behavior accrual (measuring both coital and non-coital sexual behavior). In the final triple conditional trajectory structural equation model, religiosity declined over time and then increased to baseline levels. Additionally, religiosity predicted decreased sexual conservatism and decreased sexual conservatism predicted increased sexual behavior. The final models are indicative of young women's increasing accrual of sexual experience, decreasing sexual conservatism and initial decreasing religiosity. The results of this study suggest that decreased religiosity affects the accrual of sexual experience through decreased sexual conservatism. Effective strategies of sexual health promotion should include an understanding of the complex role of socio-sexual attitudes with religiosity.

  17. Concealed fertility and extended female sexuality in a non-human primate (Macaca assamensis.

    Directory of Open Access Journals (Sweden)

    Ines Fürtbauer

    Full Text Available In numerous primates living in mixed-sex groups, females display probabilistic cues of fertility to simultaneously concentrate paternity to dominant males while diluting it amongst others as a means to reduce the risk of infanticide and to increase male care for offspring. A few species, however, lack these cues and potentially conceal fertility from males; yet, to date, little is known about mating patterns and their underlying proximate mechanisms in such species. Here, we investigated mating activity and sexual consortships relative to female reproductive state in wild Assamese macaques (Macaca assamensis, a species where females lack prominent anogenital swellings and copulation calls. During two mating seasons (2837 contact hours we recorded sexual and social behaviors, sexual consortships, and collected 1178 fecal samples (n = 15 females which were analyzed for progestogen concentrations to assess female reproductive state and to determine the timing of ovulation and conception. Although mostly conceiving in their first ovarian cycle, females were sexually receptive throughout the entire 4-month mating season, and within-cycle mating frequencies were not increased during fertile phases. Dominant males did not monopolize fertile matings, and consortships by high-ranking males lasted for long periods, which were not exclusively linked to female fertile phases. Furthermore, females copulated promiscuously but not randomly, i.e. for almost every female, matings were concentrated to a certain male, irrespective of male rank. Collectively, we demonstrate that fertility is undisclosed to males. The extreme extended female sexuality facilitated by concealed fertility may allow females to create differentiated mating relationships within a promiscuous mating system. Our study provides important new insight into the plasticity of female sexuality in non-human primates.

Methods Of 256 admitted detained adolescent females aged 12–18 years, a representative sample (N = 212, 83% was examined in the first month of detention. Instruments included a semi-structured interview, standardized questionnaires and file information on pregnancy, sexuality related characteristics (sexual risk behavior, multiple sex partners, sexual trauma, lack of assertiveness in sexual issues and early maturity and mental health characteristics (conduct disorder, alcohol and drug use disorder and suicidality. Results Approximately 20% of the participants reported having been pregnant (before detention, although none had actually given birth. Sexuality related characteristics were more prevalent in the pregnancy group, while this was not so for the mental health characteristics. Age at assessment, early maturity, sexual risk behavior, and suicidality turned out to be the best predictors for pregnancy. Conclusion The lifetime prevalence of pregnancy in detained adolescent females is high and is associated with both sexuality related risk factors and mental health related risk factors. Therefore, prevention and intervention programs targeting sexual risk behavior and mental health are warranted during detention.

    2017-02-01

    The impact of sexual fantasies in future risk and treatment response among sexual offenders has long been known. However, as we develop objective self-report measures of sexual fantasies, response bias is becoming an increasing concern. In examining a sample of institutionalized sex offenders, the present study suggests that offenders' responses on these measures are prone to response bias, the bias does not negate their associations with other self-report measures of sexual deviance, and relationship of their sexual fantasies does not appear to relate to actual behavioral indications. Clinical and research implications for these findings are discussed.

However, there have been few studies of unmarried migrant females' sexual knowledge, attitudes and behaviors, which is important for sexual health education and promotion. Methods A sample of 5156 unmarried migrant female workers was selected from three manufacturing factories, two located in Shenzhen and one in Guangzhou, China. Demographic data, sexual knowledge, attitudes and behaviors were assessed by self-administered questionnaires. Multivariate logistic regression analysis was conducted to examine the factors associated with premarital sexual intercourse. Results The average age of the unmarried female workers included in the sample was 20.2 years, and majority of them showed a low level of sex-related knowledge. Females from the west of China demonstrated a significant lower level of sex-related knowledge than those from the eastern or central provinces (p p p Conclusion The unmarried migrant female workers lack sexual knowledge and a substantial proportion of them are engaged in premarital sexual behaviors. Interventions aimed at improving their sexual knowledge and related skills are needed.

  12. Exploiting a moment of weakness: male spiders escape sexual cannibalism by copulating with moulting females.

    2015-11-26

    Sexual cannibalism is a particularly extreme example of conflict between the sexes, depriving the male of future reproduction. Theory predicts that sexual conflict should induce counter-adaptations in the victim. Observations of male spiders mating with moulting and hence largely immobile females suggest that this behaviour functions to circumvent female control and cannibalism. However, we lack quantitative estimates of natural frequencies and fitness consequences of these unconventional matings. To understand the importance of mating while moulting in cannibalistic mating systems, we combined mating experiments and paternity assessment in the laboratory with extensive field observations using the sexually cannibalistic orb-web spider Argiope bruennichi. Copulations with moulting females resulted in 97% male survival compared with only 20% in conventional matings. Mating while moulting provided similar paternity benefits compared with conventional matings. Our findings support the hypothesis that mating with moulting females evolved under sexual conflict and safely evades sexual cannibalism. Despite male benefits, natural frequencies were estimated around 44% and directly predicted by a male guarding a subadult female. Since only adult females signal their presence, the difficulty for males to locate subadult females might limit further spreading of mating with moulting females.

    One of the reasons for the perpetuation of female circumcision is that it controls female sexuality. In this study, the authors examined the relationship between female circumcision and the sexual behavior of women in Kenya and Nigeria. Data on women who were aware of circumcision and were circumcised were extracted from the Kenya Demographic and Health Survey of 2008-09 as well as the Nigeria Demographic and Health Survey of 2008. The sample size was 7,344 for Kenya and 16,294 for Nigeria. The outcome variables were age at first intercourse and total lifetime number of sexual partners. The study hypothesis was that women who were circumcised were less likely to have initiated sex early and to have only one sex partner. Cox proportional hazards regression and Poisson regression were used to examine the relations of female circumcision and other selected variables to sexual behavior. No association was observed between female circumcision and the outcomes for sexual behavior of women in Kenya and Nigeria. The argument of sexual chastity is insufficient to sustain the perpetuation of female circumcision.

    Female ornamentation has long been overlooked because of the greater prevalence of elaborate displays in males. However, the circumstances under which females would benefit from honestly signalling their quality are limited. Females are not expected to invest in ornamentation unless the fitness benefits of the ornament exceed those derived from investing the resources directly into offspring. It has been proposed that when females gain direct benefits from mating, females may instead be selec...

    This study examines the way female and male models are portrayed in magazine advertisements. Specifically, we focus on differences in sex role stereotyping, sexual display of the body, and violent imagery. Data were collected from a stratified random sample of magazines displaying fashion and fitness advertisements (N = 254). Findings from the analysis show that females are more likely than males to be placed in submissive positions, sexually displayed, and subjects of violent imagery. Sexual display and violent imagery measures are the strongest predictors of subjective level of exploitation.

    During a household survey in Tanzania, a nationally representative sample of females and males aged 13-24 years reported any experiences of sexual violence that occurred before the age of 18 years. The authors explore the prevalence, circumstances, and health outcomes associated with childhood sexual violence. The results suggest that violence against children in Tanzania is pervasive, with roughly three in 10 females and one in eight males experiencing some form of childhood sexual violence, and its health consequences are severe. Results are being used by the Tanzanian government to implement a National Plan of Action.

  18. Sexual selection on receptor organ traits: younger females attract males with longer antennae

    Johnson, Tamara L.; Symonds, Matthew R. E.; Elgar, Mark A.

    2017-06-01

    Sexual selection theory predicts that female choice may favour the evolution of elaborate male signals. Darwin also suggested that sexual selection can favour elaborate receiver structures in order to better detect sexual signals, an idea that has been largely ignored. We evaluated this unorthodox perspective by documenting the antennal lengths of male Uraba lugens Walker (Lepidoptera: Nolidae) moths that were attracted to experimentally manipulated emissions of female sex pheromone. Either one or two females were placed in field traps for the duration of their adult lives in order to create differences in the quantity of pheromone emissions from the traps. The mean antennal length of males attracted to field traps baited with a single female was longer than that of males attracted to traps baited with two females, a pattern consistent with Darwin's prediction assuming the latter emits higher pheromone concentrations. Furthermore, younger females attracted males with longer antennae, which may reflect age-specific changes in pheromone emission. These field experiments provide the first direct evidence of an unappreciated role for sexual selection in the evolution of sexual dimorphism in moth antennae and raise the intriguing possibility that females select males with longer antennae through strategic emission of pheromones.

    Following qualitative research methodology, this article presents school-based sexual violence experiences of female learners with mild intellectual disability. A total of 16 learners aged 16 to 24 years participated in the study. The findings revealed that learners with intellectual disability are not immune to school-based sexual violence. Modes of behavior that occurred frequently included touching, threats, and intimidation. School practices that reinforced school-based sexual violence are identified. The findings contradict common misconceptions that people with intellectual disability do not understand what is happening to them. The study recommends that school policies for sexual violence be intensified and learners receive developmentally appropriate sex education.

    Vitiligo has a major effect on sexual health because of the disfiguring skin lesions affecting self-image and self-esteem. However, this topic has not explored. This article aimed to assess the effect of vitiligo on genital self-image, sexual function, and quality of life in female patients. This cross-sectional study included 50 sexually active women with vitiligo and 25 women without vitiligo. All participants subjected to full history taking and examination. Extent of vitiligo was assessed with the Vitiligo Area Scoring Index score, sexual function with the Female Sexual Function Index, genital self-image with Female Genital Self-Image Score and quality of life with the Dermatology Life Quality Index questionnaires. The main outcome measures were correlation between Vitiligo Area Scoring Index, Female Genital Self-Image Score, Female Sexual Function Index, and Dermatology Life Quality Index domains was determined using t test and Pearson correlation. This study revealed a negative correlation between the Vitiligo Area Scoring Index score and sexual satisfaction. Vitiligo Area Scoring Index and Dermatology Life Quality Index score was significantly correlated with Arabic Version of the Female Genital Self-Image Score alone and with Arabic Version of the Female Sexual Functioning Index alone and with both the Arabic Version of the Female Genital Self-Image Score and the Arabic Version of the Female Sexual Functioning Index (p vitiligo is imperative to improve outcomes and increase patients' compliance with treatment.

    Self-esteem and self-image are psychological aspects that affect sexual function. To validate a new measurement tool that correlates the concepts of self-esteem, self-image, and sexuality. A 20-question test (the self-esteem/self-image female sexuality [SESIFS] questionnaire) was created and tested on 208 women. Participants answered: Rosenberg's self-esteem scale, the female sexual quotient (FSQ), and the SESIFS questionnaire. Pearson's correlation coefficient was used to test concurrent validity of the SESIFS against Rosenberg's self-esteem scale and the FSQ. Reliability was tested using the Cronbach's alpha coefficient. The new questionnaire had a good overall reliability (Cronbach's alpha r = 0.862, p self-esteem domain r = 0.32, p self-image domain r = 0.31, p self-esteem, self-image, and sexuality domains. A new, revised version is being tested and will be presented in an upcoming publication.

    To assess sexual activity, sexual function, and their correlation with vaginal maturation status among middle-aged Chinese women. A cross-sectional study with comparisons across age groups was carried out. In all, 120 women aged 45 to 60 years were recruited into three groups: 45 to 50 (youngest group), 51 to 55 (intermediate group), and 56 to 60 years old (eldest group). Sexual function was assessed through the Female Sexual Function Index (FSFI); vaginal maturation status was determined through the Vaginal Maturation Index (VMI) and pH value. Sexual activity was recorded with self-administered questionnaires. Low sexual frequency was present in a higher proportion of women, but sexual distress was identified within a lower proportion of women in the eldest group. The total FSFI score was significantly lower in the eldest group than in the youngest and intermediate groups (P VMI (P VMI was positively correlated with the total FSFI score, the domain score for sexual desire, and lubrication (r = 0.26, 0.25, 0.34; P < 0.05, 0.05, 0.01), but the opposite associations were demonstrated for pH value (r = -0.47, -0.37, -0.38; P < 0.01, respectively), especially with vaginal pain (r = -0.44, P < 0.01). Among middle-aged Chinese women, sexual desire is lower in 56 to 60-year-old women, compared with those aged 45 to 55 years, whereas vaginal dryness and dyspareunia become more prevalent with age. Importantly, sexual function is associated with vaginal maturation status in women at midlife.

    Previous researchers have documented that the color red enhances one's sexual attraction to the opposite sex. The current study further examined the moderating role of sexual dimorphism in red effects. The results indicated that red enhanced men's sexual attraction to women with more feminine facial characteristics but had no effect on ratings of perceived general attractiveness. Red clothing also had a marginally significant effect on men's sexual attractiveness. In addition, regardless of sexual dimorphism cues, male participants rated women with red as warmer and more competent. The underlying mechanisms of the red effect, the limitations of the current study, and suggestions for future directions are discussed.

    Full Text Available Background Healthy sexual function can be considered as an important element to improve personal and public hygiene. The sexual desire plays an important role in mental health and improving the quality of life. Objectives The current study aimed to compare sexual function of females in urban and rural areas. Methods The current descriptive study adopted 800 females of reproductive age (range 15 - 45 years referred to rural and urban healthcare centers in Ahvaz, Iran, in 2015. Samples were randomly selected. Applied instruments in the study were demographic information and female sexual dysfunction questionnaires (FSFI. Independent T-test, Chi-square and logistic regression were employed to analyze data by SPSS ver. 22. Results The result showed a significant statistical difference between females in urban and rural areas in terms of sexual desire, vaginal lubrication, intercourse pain and sexual function (P 0.05. Frequency of sexual dysfunction was 59.9% in females in rural and36.5% in urban areas and the difference between the groups was statistically significant (0.000. In both groups, the highest sexual disorder frequency was related to intercourse pain. Conclusions According to the obtained results, females in the rural areas had lower sexual function than the ones in the urban areas. It is suggested to establish female sexual health units in healthcare centers to give female sexual function consultation adjusted with awareness and culture of females and consider the existing problems.

    The complexity of female sexual pain requires an interdisciplinary approach. Physical therapists trained in pelvic health conditions are well positioned to be active members of an interdisciplinary team addressing the assessment and treatment of female sexual pain. Changes within physical therapy practice in the last ten years have resulted in significant utilization of pelvic floor muscle relaxation and manual therapy techniques to address a variety of pelvic pain conditions, including female sexual pain. However, sexual pain is a complex issue giving credence to the necessity of addressing all of the drivers of the pain experience- biological, psychological and social. This review aims to reconcile current pain science with a plan for integrating a biopsychosocial approach into the evaluation and subsequent treatment for female sexual pain for physical therapists. A literature review of the important components of skilled physical therapy interventions is presented including the physical examination, pain biology education, cognitive behavioral influences in treatment design, motivational interviewing as an adjunct to empathetic practice, and the integration of non-threatening movement and mindfulness into treatment. A single case study is used to demonstrate the biopsychosocial framework utilized in this approach. Appropriate measures for assessing psychosocial factors are readily available and inform a reasoned approach for physical therapy design that addresses both peripheral and central pain mechanisms. Decades of research support the integration of a biopsychosocial approach in the treatment of complex pain, including female sexual pain. It is reasonable for physical therapists to utilize evidence based strategies such as CBT, pain biology education, Mindfulness Based Stress Reduction (MBSR), yoga and imagery based exercises to address the biopsychosocial components of female sexual pain.

    We previously showed that estradiol can have both defeminizing and feminizing effects on the developing mouse brain. Pre- and early postnatal estradiol defeminized the ability to show lordosis in adulthood, whereas prepubertal estradiol feminized this ability. Furthermore, we found that estradiol upregulates progesterone receptors (PR) during development, inducing both a male-and female-typical pattern of PR expression in the mouse hypothalamus. In the present study, we took advantage of a newly developed PR antagonist (ZK 137316) to determine whether PR contributes to either male- or female-typical sexual differentiation. Thus groups of male and female C57Bl/6j mice were treated with ZK 137316 or OIL as control: males were treated neonatally (P0-P10), during the critical period for male sexual differentiation, and females were treated prepubertally (P15-P25), during the critical period for female sexual differentiation. In adulthood, mice were tested for sexual behavior. In males, some minor effects of neonatal ZK treatment on sexual behavior were observed: latencies to the first mount, intromission and ejaculation were decreased in neonatally ZK treated males; however, this effect disappeared by the second mating test. By contrast, female mice treated with ZK during the prepubertal period showed significantly less lordosis than OIL-treated females. Mate preferences were not affected in either males or females treated with ZK during development. Taken together, these results suggest a role for PR and thus perhaps progesterone in the development of lordosis behavior in female mice. By contrast, no obvious role for PR can be discerned in the development of male sexual behavior.

    International students make up an increasing proportion of university students in Australia. Research suggests that they have poor sexual health knowledge compared with local students. Thematic analysis was undertaken on focus groups carried out at the University of Adelaide (South Australia), with 21 female international students from Malaysia and China. Four themes were identified: poor sexual health knowledge; complex attitudes about premarital sex; difficulty accessing sexual health information, and poor understanding the role of general practitioners in this area; and ideas about future education. Participants believed that international students have insufficient sexual health education when they arrive in Australia. They were concerned that some students may become more sexually active in Australia, and may not have adequate access to health services and information. All participants felt it was necessary for international students to receive better sexual health education. International students are important to Australian universities, and it should be mandatory to ensure that culturally appropriate sex education is made available to this group.

    Background There are scant data related to sexuality assessed among mid-aged women from Paraguay. Objective To assess sexual function in a sample of mid-aged Paraguayan women. Methods This was a cross-sectional study in which 265 urban-living women from Asunción (Paraguay) aged 40-65 years were surveyed with the six-item version of the Female Sexual Function Index (FSFI-6) and a questionnaire containing personal and partner data. Results The median age of the sample was 48 years, 48.2% were postmenopausal (median/interquartile range age at menopause 46/13 years), 11.3% used hormone therapy, 37.0% used psychotropic drugs, 44.5% had hypertension, 7.2% diabetes, 46.1% abdominal obesity and 89.4% had a partner (n = 237). Overall, 84.1% (223/265) of surveyed women were sexually active, presenting a median total FSFI-6 score of 23.0, and 25.6% obtained a total score of 19 or less, suggestive of sexual dysfunction (lower sexual function). Upon bivariate analysis, several factors were associated with lower total FSFI-6 scores; however, multiple linear regression analysis found that lower total FSFI-6 scores (worse sexual function) were significantly correlated to the postmenopausal status and having an older partner, whereas coital frequency was positively correlated to higher scores (better sexual function). Conclusion In this pilot sample of urban-living, mid-aged Paraguayan women, as determined with the FSFI-6, lower sexual function was related to menopausal status, coital frequency and partner age. There is a need for more research in this regard in this population.

    The abundance of sperm relative to eggs selects for males that maximize their number of mates and for females that choose high quality males. However, in many species, males exercise mate choice, even when they invest little in their offspring. Sexual cannibalism may promote male choosiness by limiting the number of females a male can inseminate and by biasing the sex ratio toward females because, while females can reenter the mating pool, cannibalized males cannot. These effects may be insufficient for male choosiness to evolve, however, if males face low sequential encounter rates with females. We hypothesized that sexual cannibalism should facilitate the evolution of male choosiness in group living species because a male is likely to encounter multiple receptive females simultaneously. We tested this hypothesis in a colonial orb-weaving spider, Cyrtophora citricola, with a high rate of sexual cannibalism. We tested whether mated females would mate with multiple males, and thereby shift the operational sex ratio toward females. We also investigated whether either sex chooses mates based on nutritional state and age, and whether males choose females based on reproductive state. We found that females are readily polyandrous and exhibit no mate choice related to male feeding or age. Males courted more often when the male was older and the female was younger, and males copulated more often with well-fed females. The data show that males are choosier than females for the traits we measured, supporting our hypothesis that group living and sexual cannibalism may together promote the evolution of male mate choice.

    We studied the development of sexual behaviors in female Japanese macaques (Macaca fuscata) living at Arashiyama, Japan, in a group where adult females routinely exhibit sexual interactions with both males and females. Our cross-sectional data on juvenile, adolescent, and adult females supported most of our predictions related to the learning hypothesis, which holds that adolescence serves to provide females with a period in which to practice adult female-like sexual behavioral patterns, including sexual solicitations, sexual mounts, and spatio-temporal coordination during consortships. We found evidence for a gradual acquisition of adult-like behavioral patterns (e.g., more frequent solicitations with body contact, more frequent complete mounts, more diverse solicitation patterns and complete mounting postures, and longer consortships involving prolonged inter-mount grasping behavior between partners), and a gradual disappearance of less effective immature behavioral patterns (e.g., less frequent non-contact solicitations, ambiguous mounting initiations, and incomplete mounts). We distinguished between three major categories of sexual behavioral patterns based on their speed of development, ranging from fast (e.g., diversity in mounting postures and genital stimulation during mounting) to slow (e.g., contact solicitations and grasping behavior between consortship partners), with some being intermediate (e.g., range of solicitation patterns and expression of complete mounts). This study showed that the emergence of both conceptive and non-conceptive adult sexual behaviors can be traced back to immature behavioral patterns in adolescent female Japanese macaques, with a major threshold occurring at the age of 4 years.

    This study aimed to investigate the relations of adolescent sexual experiences (particularly early initiation) to a spectrum of emotional/behavioral problems and to probe possible gender difference in such relationships. The 10th (N = 8,842) and 12th (N = 10,083) grade students, aged 16-19 years, participating in national surveys in 2005 and 2006 in Taiwan were included for this study. A self-administered web-based questionnaire was designed to collect information on sociodemographic characteristics, sexual experience, substance use, and the Youth Self-Report Form. For the sexually experienced adolescents, their sexual initiation was classified as early initiation (initiation (16-19 years). Gender-specific multivariate response profile regression was used to examine the relationship between sexual experience and the behavioral syndromes. Externalizing problems, including Rule-breaking Behavior and Aggressive Behavior, were strongly associated with sexual initiation in adolescence; the magnitude of the association increased for earlier sexual initiation, especially for females. As to internalizing problems, the connection was rather heterogeneous. The scores on some syndromes, such as Somatic Complaints and Anxious/Depressed, were higher only for females with early or non-early sexual initiation whereas the score on Withdrawn, along with Social Problems that is neither internalizing nor externalizing, was lower for the sexually experienced adolescents than for the sexually inexperienced ones. We concluded that earlier sexual initiation was associated with a wider range of behavioral problems in adolescents for both genders, yet the increased risk with emotional problems was predominately found in females.

    Receptive female mouse placed in a cage behind a partition which prevented physical contacts but allowed the female to be smelt and seen produced in CBA and A/He males an elevation of plasma testosterone level and increase in time spent near the partition (TSNP) in attempts to reach the female. Both in CBA and A/He males the TSNP was much higher than in controls with empty adjacent compartment or with a male in it. The number of approaches to the partition was also increased but not sex-depended reflecting the general motor excitement of animals. A 3-4-fold increase in the TSNP preceding blood testosterone elevation was found within the first 10 min of female exposure. It was suggested that sexual motivation in males induced by female exposure was not caused by testosterone increase. The TSNP in male mice produced by female exposure can be used as an adequate index of sexual motivation.

    The aim of our study was to describe the impact of mid-urethral sling procedure for the treatment of stress urinary incontinence (SUI) on female sexual function. We used PubMed (updated March 2015) to conduct a literature electronic search that included peer-reviewed English language articles. We analyzed the studies about the impact of mid-urethral slings on female sexual function. There are different and contradictory results of the effects of mid-urethral sling on female sexual function. However, more papers show that women undergoing mid-urethral sling procedures report that their sexual function is improved or remains unchanged. The main mechanism of this improved sexuality is the complete relief from coital incontinence, reduction in anxiety and avoidance of sex, whereas the most common symptom related to worsened sexual activity is dyspareunia. Women undergoing sling procedures for SUI should be informed that their sexual activity is likely to remain unchanged or even improve after the operation, but that dyspareunia may occur.

    Refugees and internally displaced persons are highly vulnerable to sexual violence during conflict and subsequent displacement. However, accurate estimates of the prevalence of sexual violence among in these populations remain uncertain. Our objective was to estimate the prevalence of sexual violence among refugees and displaced persons in complex humanitarian emergencies. We conducted systematic review of relevant literature in multiple databases (EMBASE, CINAHL, and MEDLINE) through February 2013 to identify studies. We also reviewed reference lists of included articles to identify any missing sources. Inclusion criteria required identification of sexual violence among refugees and internally displaced persons or those displaced by conflict in complex humanitarian settings. Studies were excluded if they did not provide female sexual violence prevalence, or that included only single case reports, anecdotes, and those that focused on displacement associated with natural disasters. After a review of 1175 citations 19 unique studies were selected. Two reviewers worked independently to identify final selection and a third reviewer adjudicated any differences. Descriptive and quantitative information was extracted; prevalence estimates were synthesized. Heterogeneity was assessed using I2. The main outcome of interest was sexual violence among female refugees and internally displaced persons in complex humanitarian settings. The prevalence of sexual violence was estimated at 21.4% (95% CI, 14.9-28.7; I2=98.3%), using a random effects model. Statistical heterogeneity was noted with studies using probability sampling designs reporting lower prevalence of sexual violence (21.0%, 95% CI, 13.2-30.1; I2=98.6%), compared to lower quality studies (21.7%, 95% CI, 11.5-34.2; I2=97.4%). We could not rule out the presence of publication bias. The findings suggest that approximately one in five refugees or displaced women in complex humanitarian settings experienced sexual violence

    We examined the association between depression and sexual violence among 18-24 year-old female college students using National College Health Assessment survey. Data were collected from a nationally representative sample of 10,541 female students on 33 college campuses. Results showed that female students who were reportedly ever diagnosed with depression were 1.56 times more likely than those who had never been diagnosed with depression to have experienced sexual violence. Female students who had one or more sexual partners currently were found 3.17 times more likely than those who had no sexual partner to have experienced sexual violence; similarly, female students who engaged in binge drinking in the previous two weeks were found about two times more likely than their counterparts to have experienced sexual violence. Depression is a public health issue and must be addressed sooner rather than later in order to reduce and prevent sexual violence on college campuses.

    The reproductive health of adolescents and young women is integral to the wellbeing of a society. This study was carried out to determine current sexual practices and contraceptive usage among female undergraduate students in a Southwest Nigerian tertiary institution. It was a cross-sectional questionnaire based survey of female university undergraduates. Pre-tested questionnaire was used to elicit information on socio-demographic variables and sexual and contraceptive practices. Frequency tables were generated and univariate and multivariate logistic regressions were used to determine factors that influenced sexual and contraceptive practices. SPSS software version 16.0 was used for analysis. Of 350 students sampled, 306 completed the questionnaire. One hundred and eighty six (60.8%) students were currently sexually active. The mean age of sexual debut was 19.11 years. Sixty-six (35.5%) had more than one sexual partners. Contraceptive knowledge was 100%, but consistent use was 34.4%. A third of the respondents had sex for material rewards and/or under the influence of alcohol and recreational drugs. Students who were less than 20 years old (Adjusted OR: 3.52; 95%CI=2.10-6.82) were more likely to be sexually active while those from polygamous/separated families (Adjusted OR: 0.32; 95% CI=0.18-0.58) were less likely to be sexually active. There is a high level of sexual activity and low contraceptive use among female undergraduate students in Southwest Nigeria. More reproductive health education and promotion is necessary to safeguard their sexual health.

    Prezygotic reproductive isolation can evolve quickly when sexual selection drives divergence in traits important for sexual interactions between populations. It has been hypothesized that standing variation for male/female traits and preferences facilitates this rapid evolution and that variation in these traits is maintained by male-female genotype interactions in which specific female genotypes prefer specific male traits. This hypothesis can also explain patterns of speciation when ecological divergence is lacking, but this remains untested because it requires information about sexual interactions in ancestral lineages. Using a set of ancestral genotypes that previously had been identified as evolving reproductive isolation, we specifically asked whether there is segregating variation in female preference and whether segregating variation in sexual interactions is a product of male-female genotype interactions. Our results provide evidence for segregating variation in female preference and further that male-female genotype interactions are important for maintaining variation that selection can act on and that can lead to reproductive isolation.

    The objective was to describe the sexual life satisfaction of couples in the climacteric stage and determine whether there are differences between the perception of satisfaction and the sex life of each partner. We studied 142 couples obtained by stratified sampling of family health centers, Concepción, Chile. 66% of women and 84% of men reported being very or somewhat satisfied with their sex lives. Slight concordance was found between the responses of the partners in relation to satisfaction with their sexual life. Moreover, a slight degree of agreement was found between the sexual life satisfaction reported by women and their partners' perceptions of the women's sexual life satisfaction. Additionally, a slight degree of agreement was reported between the sexual life satisfaction reported by men and their partners' perceptions of the men's sexual life satisfaction. This study provides new information about Chilean couples in the climacteric stage in relation to self-reported sexual satisfaction and perceived satisfaction in couples.

    We explore what it means to promote healthy sexuality for incarcerated women. We report upon the experiences of ten inmates in the Female Central Penitentiary of Santiago, Chile, regarding their sexuality within prison. We used a qualitative, descriptive research approach. Individual and semistructured interviews were conducted with women from different sections of the prison over a 2-month period. Participants highlighted the site for conjugal visits, the Venusterio, as a place of privacy and sexual expression between couples from outside prison. Motivated by loneliness, need of protection, and desire for affection, participants enacted alternate gender and sexual identities and sexual orientation. Some previously heterosexual women became 'machos', women taking on dominant masculine identities. Women found a paradoxical freedom to express a malleable and fluid sexual identity, an identity that might not go outside the prison. Informed by Judith Butler's idea of performativity, we argue that women could enact both different gender and sexual identities in search of satisfying their affective and erotic desires while under the duress of incarceration. The findings suggest a need for a more fluid understanding of gender and sexuality, especially for those midwives and nurses who strive to promote sexual health, not only reproductive health.

  18. Straight but Not Narrow; Within-Gender Variation in the Gender-Specificity of Women's Sexual Response.

    Full Text Available Gender differences in the specificity of sexual response have been a primary focus in sexual psychophysiology research, however, within-gender variability suggests sexual orientation moderates category-specific responding among women; only heterosexual women show gender-nonspecific genital responses to sexual stimuli depicting men and women. But heterosexually-identified or "straight" women are heterogeneous in their sexual attractions and include women who are exclusively androphilic (sexually attracted to men and women who are predominantly androphilic with concurrent gynephilia (sexually attracted to women.

The current studies investigated within-gender variability in the gender-specificity of women's sexual response. Two samples of women reporting concurrent andro/gynephilia viewed (Study 1, n = 29 or listened (Study 2, n = 30 to erotic stimuli varying by gender of sexual partner depicted while their genital and subjective sexual responses were assessed. Data were combined with larger datasets of predominantly gyne- and androphilic women (total N = 78 for both studies. In both studies, women reporting any degree of gynephilia, including those who self-identified as heterosexual, showed significantly greater genital response to female stimuli, similar to predominantly gynephilic women; gender-nonspecific genital response was observed for exclusively androphilic women only. Subjective sexual arousal patterns were more variable with respect to sexual attractions, likely reflecting stimulus intensity effects. Heterosexually-identified women are therefore not a homogenous group with respect to sexual responses to gender cues. Implications for within-gender variation in women's sexual orientation and sexual responses are discussed.

    Protogynous hermaphroditism, female-to-male sex change, is well known among reef fishes where large males monopolize harems of females. When the dominant male disappears from a harem, the largest female may change sex within a few weeks. Recently, from experiments with some protogynous haremic fishes in which two males' cohabitated, it was confirmed that sexual behavior and gonads were completely reversible according to individual social status. However, the ability to reverse secondary-developed sexual body coloration has never been examined in any protogynous fish. We conducted two male cohabitation experiments with the protogynous haremic angelfish, Centropyge ferrugata, which has conspicuous sexual dichromatism on the dorsal fin. Smaller males of C. ferrugata soon performed female-specific mating behaviors when they became subordinated after losing a contest. They then completed gonadal sex change to females 47 or 89 d (n=2) after beginning cohabitation. In the course of the reversed gonadal sex change, male-specific coloration on the dorsal fin changed to that of a female. Thus, the sex of C. ferrugata, including secondary developed sexually dichromatic characteristics, can be completely reversible in accord with their social status.

  1. Unusual allometry for sexual size dimorphism in a cichlid where males are extremely larger than females

    When males are the larger sex, a positive allometric relationship between male and female sizes is often found across populations of a single species (i.e. Rensch’s rule). This pattern is typically explained by a sexual selection pressure on males. Here, we report that the allometric relationship was negative across populations of a shell-brooding cichlid fish Lamprologus callipterus, although males are extremely larger than females. Male L. callipterus collect and defend empty snail shells in each of which a female breeds. We found that, across six populations, male and female sizes are positively correlated with not only sexual and fecundity selection indices, but also with shell sizes. Given their different reproductive behaviours, these correlations mean that males are required to be more powerful, and thus larger, to transport larger shells, while female bodies are reduced to the shell size to enable them to enter the shells. Among the three size selections (sexual selection, fecundity selection and shell size), shell size explained the allometry, suggesting that females are more strongly subject to size selection associated with shell size availability than males. However, the allometry was violated when considering an additional population where size-selection regimes of males differed from that of other populations. Therefore, sexual size allometry will be violated by body size divergence induced by multiple selection regimes.

    Little is known about the sexual and reproductive health care needs of female sex workers in Dhaka, Bangladesh. Survey data were collected from 354 hotel-based and 323 street-based female sex workers using a venue-based stratified cluster sampling approach. In addition, in-depth interviews were conducted with 20 female sex workers recruited from drop-in centers. We calculated unmet need for family planning and examined fertility desires, use of condoms and other contraceptive methods, experiences with gender-based violence, sexual and reproductive health service needs, and preferences on where to receive services. The prevalence of unmet need was 25% among hotel-based female sex workers and 36% among street-based female sex workers. Almost all participants reported having used condoms in the past 30 days, and 44% of hotel-based sex workers and 30% of street-based sex workers reported dual method use during that period. Condom use was inconsistent, however, and condom breakage and nonuse for extra money were common. Many women reported experiencing gender-based violence. Sexual and reproductive health services had been obtained by 64% of hotel-based and 89% of street-based sex workers in the past six months; drop-in centers were their preferred site for receiving health services. Female sex workers in Dhaka need family planning and other sexual and reproductive health services and prefer receiving them from drop-in centers.

    The aim of this study is to investigate the association of sexual functions with levator hiatus biometry measurements and levator ani muscle defect. In 62 heterosexual, sexually active premenopausal women without pelvic floor disorders or urinary incontinence, 3-dimensional transperineal ultrasound imaging was used. Two 3-dimensional volumes were recorded, one at rest and one on Valsalva maneuver. Levator biometry measurements and levator defect were evaluated in an axial plane. Sexual function was assessed by a validated questionnaire, Female Sexual Function Index (FSFI). The primary outcome measure was correlation of sexual functions with the levator hiatus area, transverse and anteroposterior diameters, levator ani muscle thickness, vaginal length, and changes in measurements with Valsalva and levator defect. Forty-two women (67.7%) had low total FSFI scores (<26.55). Levator defect rates were similar in female sexual dysfunction (7/42, 16.7%) and women without female sexual dysfunction (5/20, 25%). The FSFI was negatively and weakly correlated with Δhiatal anteroposterior diameter (r = -0.33, P < 0.009) in the study population. There was a weak and inverse correlation between Δhiatal anteroposterior diameter and arousal (r = -0.35, P < 0.002), desire (r = -0.38, P < 0.001), and orgasm (r = -0.33, P < 0.007). Pain and lubrication did not correlate with any measurement. Hiatal area and diameters at rest are not related to sexual functions. Changes in anteroposterior diameter of the levator hiatus during Valsalva, which may be a sign of pelvic floor laxity or levator muscle weakness, are weakly associated with sexual functions, particularly desire, arousal, and orgasm domains.

    Homosexual and nonhomosexual (relative to genetic sex) female-to-male transsexuals (FTMs) were compared on a number of theoretically or empirically derived variables. Compared to nonhomosexual FTMs, homosexual FTMs reported greater childhood gender nonconformity, preferred more feminine partners, experienced greater sexual rather than emotional jealousy, were more sexually assertive, had more sexual partners, had a greater desire for phalloplasty, and had more interest in visual sexual stimuli. Homosexual and nonhomosexual FTMs did not differ in their overall desire for masculinizing body modifications, adult gender identity, or importance of partner social status, attractiveness, or youth. These findings indicate that FTMs are not a homogeneous group and vary in ways that may be useful in understanding the relation between sexual orientation and gender identity.

  5. Emotional concerns and treatment of male partners of female sexual abuse survivors.

    Many men are discovering that they are involved with women who were sexually abused as children. However, male partners of female sexual abuse survivors have thus far received little attention in the literature. As these men increasingly seek treatment with concerns of their own, social workers must become familiar with their emotional experiences and treatment needs. This article outlines the major concerns expressed by 20 male partners of sexual abuse survivors. These concerns included conflicts about expressing needs, frustration with various aspects of their relationships, guilt and shame at having feelings, questions about how to deal with relatives, and sexual issues. The author recommends a treatment approach that combines attention to both the individual's and the couple's concerns and uses insight and the safety of the therapeutic relationship to promote growth. The importance of further outreach to partners of women who were sexually abused as children and the need for increased attention to other partner populations are highlighted.

    Sexual dimorphism is common in polygynous species, where intrasexual competition is often thought to drive the evolution of large male body size, and in turn, male behavioral dominance over females. In Madagascar, the entire lemur radiation, which embraces diverse mating systems, lacks sexual dimorphism and exhibits frequent female dominance over males. The evolution of such morphological and behavioral peculiarities, often referred to as "the lemur syndrome," has proven difficult to understand. Among other hypotheses, a potential role of intersexual selection has been repeatedly proposed but hardly ever tested. Here, we investigate whether female choice favors small and compliant males, and whether male choice favors large females in captive gray mouse lemurs (Microcebus murinus). Detailed analysis of a combination of behavioral observations and hormonal data available for both sexes shows that (1) females accept more matings from males with higher fighting abilities, (2) males adjust their investment in intrasexual competition to female fertility, and (3) both male and female strategies are weakly influenced by the body mass of potential partners, in directions contradicting our predictions. These results do not suggest a prominent role of intersexual selection in the evolution and maintenance of the lemur syndrome but rather point to alternative mechanisms relating to male-male competition, specifically highlighting an absence of relationship between male body mass and fighting ability. Finally, our findings add to the growing body of evidence suggesting flexible sex roles, by showing the expression of mutual mate choice in a female-dominant, sexually monomorphic and promiscuous primate.

    A well-defined season of sexual rest controlled by photoperiod is observed in female sheep and goats during spring and summer, delineating their "anestrous season"; bucks also decrease sexual activity at about the same time. Nutrition and/or socio-sexual stimuli play only secondary roles. However, the presence of sexually active males can reduce the length of seasonal anestrus. Whether it can also completely suppress anestrus has not been investigated. Here we tested this in goats in 3 experiments, using bucks rendered sexually active out of season by exposure to long days. The continuous presence of these males prevented goats to display seasonal anestrus: 12/14 females cycled the year round, vs. 0/13 and 0/11 for females with un-treated bucks or without bucks (experiment 1). When active bucks were removed, females immediately entered anestrus (7/7 stopped ovulating vs. 1/7 if maintained with active bucks; experiment 2). Finally, 7/7 anestrous does with bucks in sexual rest since 1.5months commenced cycling rapidly during mid-anestrous, when these bucks became sexually active following a treatment with artificial long days, vs. 0/7 with un-treated bucks or no bucks (experiment 3). The presence/withdrawal of active bucks had a highly significant effect in the three experiments (P≤0.002). Therefore, the presence of a mating opportunity can completely override the photoperiodic inhibition of reproduction of females throughout the anestrous season. Results suggest that we must re-evaluate the relative contributions of photoperiod vs. other external cues in controlling seasonal reproduction, thus offering new non-pharmaceutical ways for controlling out-of-season reproduction in small ruminants.

    Full Text Available Female sexual hormones have attracted the attention of the scientific community due to the effects that they cause by interfering in the endocrine system. Many contemporary studies have sought to monitor some of the main female sexual hormones in surface waters in Brazil. Current article evaluates the presence of 17β-estradiol, 17α-ethinylestradiol, estrone and progesterone in the surface waters of Curitibaand the surrounding metropolitan area in the state of Paraná, Brazil, by high-performance liquid chromatography (HPLC, performed at 7 different sites. The study revealed that a range of concentrations between 0.07 and 13.45 µg L-1 of female sexual hormones was extant; higher values than these were found in other regions ofBrazil and in other countries. Higher concentrations have been attributed to the region´s sanitation due to large sewage amounts. Sewage discharge has also been confirmed by results of limnological parameters.

    Previous research suggests that heterosexual women's sexual arousal patterns are nonspecific; heterosexual women demonstrate genital arousal to both preferred and nonpreferred sexual stimuli. These patterns may, however, be related to the intense and impersonal nature of the audiovisual stimuli used. The current study investigated the gender specificity of heterosexual women's sexual arousal in response to less intense sexual stimuli, and also examined the role of relationship context on both women's and men's genital and subjective sexual responses. Assessments were made of 43 heterosexual women's and 9 heterosexual men's genital and subjective sexual arousal to audio narratives describing sexual or neutral encounters with female and male strangers, friends, or long-term relationship partners. Consistent with research employing audiovisual sexual stimuli, men demonstrated a category-specific pattern of genital and subjective arousal with respect to gender, while women showed a nonspecific pattern of genital arousal, yet reported a category-specific pattern of subjective arousal. Heterosexual women's nonspecific genital response to gender cues is not a function of stimulus intensity or relationship context. Relationship context did significantly affect women's genital sexual arousal--arousal to both female and male friends was significantly lower than to the stranger and long-term relationship contexts--but not men's. These results suggest that relationship context may be a more important factor in heterosexual women's physiological sexual response than gender cues.

    Studies of mating preferences have largely neglected the potential effects of individuals encountering their previous mates ('directly sexually familiar'), or new mates that share similarities to previous mates, e.g. from the same family and/or environment ('phenotypically sexually familiar'). Here, we show that male and female Drosophila melanogaster respond to the direct and phenotypic sexual familiarity of potential mates in fundamentally different ways. We exposed a single focal male or female to two potential partners. In the first experiment, one potential partner was novel (not previously encountered) and one was directly familiar (their previous mate); in the second experiment, one potential partner was novel (unrelated, and from a different environment from the previous mate) and one was phenotypically familiar (from the same family and rearing environment as the previous mate). We found that males preferentially courted novel females over directly or phenotypically familiar females. By contrast, females displayed a weak preference for directly and phenotypically familiar males over novel males. Sex-specific responses to the familiarity of potential mates were significantly weaker or absent in Orco(1) mutants, which lack a co-receptor essential for olfaction, indicating a role for olfactory cues in mate choice over novelty. Collectively, our results show that direct and phenotypic sexual familiarity is detected through olfactory cues and play an important role in sex-specific sexual behaviour.

    In an earlier study, we reported that daily fluoxetine treatment (10 mg/kg/day) rapidly disrupted estrous cyclicity and sexual receptivity in adult, regularly cycling Fischer rats. The current study was designed to investigate if comparable fluoxetine treatment would similarly affect intact, regularly cycling Sprague Dawley rats. In the first experiment, fluoxetine was injected for 24 days. After 11-14 days of daily fluoxetine treatment, 40% of the rats showed a transient disturbance of the estrous cycle with elimination of sexual receptivity. In these affected rats, reduced sexual receptivity generally preceded disruption of vaginal cyclicity. In a second experiment, a shorter exposure was used to attempt to dissociate effects of fluoxetine on behavior and estrous cyclicity. Nine days of fluoxetine treatment eliminated sexual receptivity and proceptivity (hops/darts) in 40% and 46%, respectively, of rats without altering the estrous cycle. Female rats then received a 10th fluoxetine injection 30 min prior to assessment of sexual motivation (measured with the male preference paradigm). There was no effect of fluoxetine on male preference, but fluoxetine significantly reduced the number of crossings and seconds of grooming during preference testing. Therefore, effects of fluoxetine on estrous cyclicity and behavior of Sprague Dawley female rats were smaller and required longer to develop than previously reported in Fischer female rats. These findings reinforce a probable relationship between fluoxetine's effect on sexual activity and neuroendocrine disturbances and illustrate the importance of strain selection in attempting to model human disease.

    Although sexual dysfunction is an important public-health problem in Nigeria, little research has been conducted on this topic in Nigeria. This cross-sectional study was conducted to determine the prevalence of sexual dysfunction and their correlates among female patients of reproductive age using a questionnaire. Respondents were recruited from the out-patients clinics of a teaching hospital setting in Ile-Ife/ Ijesa administrative health zone, Osun State, Nigeria. Of 384 female patients interviewed, 242 (63%) were sexually dysfunctional. Types of sexual dysfunction included disorder of desire (n=20; 8.3%), disorder of arousal (n=l 3; 5.4%), disorder of orgasm (n=154; 63.6%), and painful coitus (dyspareunia) (n=55; 22.7%). The peak age of sexual dysfunction was observed among the age-group of 26-30 years. Women with higher educational status were mostly affected. The reasons for unsatisfactory sexual life mainly included psychosexual factors and medical illnesses, among which included uncaring partners, present illness, excessive domestic duties, lack of adequate foreplay, present medication, competition among wives in a polygamous family setting, previous sexual abuse, and guilt-feeling of previous pregnancy termination among infertile women. The culture of male dominance in the local environment which makes women afraid of rejection and threats of divorce if they ever complain about sexually-related matters might perpetrate sexual dysfunction among the affected individuals. Sexual dysfunction is a real social and psychological problem in the local environment demanding urgent attention. It is imperative to carry out further research in society at large so that the health and lifestyles of affected women and their partners could be improved.

    The objective of this study was to explore the associations of sources, content, and timing of reproductive health education with cognitive and behavioral sexual risk in a sample of high-risk female adolescents and young adults. Female adolescents and young adults (n=113, median age 17 years) receiving treatment for a sexually transmitted disease (STD) reported sources of reproductive health education, topics covered, and when first formal education occurred. Dependent variables included sexual risk knowledge; condom attitudes, negotiation skills, and use (consistent and at last sex); and number of sexual partners. Most participants reported receiving reproductive health education from both parental (80%) and formal sources (92%). Parents discussed the menstrual cycle (94%) more frequently than other sex education topics, while formal sources focused most on teaching about STDs (91%). Although median age of first formal instruction was 12 years, 26% of girls received their first formal education during or after the year they initiated coitus. Girls with a parental source of education and those receiving formal instruction on pregnancy reported greater ability to negotiate condom use. Girls who received education later in relation to the onset of sexual activity and those with a parental source of education reported more sexual partners. Early reproductive health education and education from both parental and formal sources is associated with reduced sexual risk among high-risk adolescent girls. Interestingly, receiving parental education is also associated with more sexual partners, suggesting that parental educational efforts may be reactive to their daughters' increasing sexual risk behavior. Future research should examine multiple sources of reproductive health education and the timing of education from these sources to enhance understanding the dynamic interactions between reproductive health education and adolescent sexual risk.

    The aim of this study is to describe sexual harassment among Italian university students and analyze the relationship between harassment and disordered eating behaviors. An observational survey was conducted among university students at Trieste University (Italy) in spring 2014. Students answered an anonymous self-administered questionnaire about sexual harassment, including three domains-sexual harassment, unwanted comments on physical appearance, cyber-harassment-and disordered eating behaviors. The global sexual harassment index was computed with three levels: Level 0, no harassment; Level 1, harassment in at least one of the three domains; and Level 2, harassment in two or three domains. Disordered eating behaviors were classified by at least one of the following: (a) eating without being able to stop or vomiting at least once or twice a month, (b) using laxatives or diuretics at least once or twice a week, (c) monitoring weight every day, and (d) dieting at least very often. The sample included 759 students (347 men and 412 women; 18-29 years old). Experiencing sexual harassment was related to eating disorder symptoms for both genders with a regular gradient: the higher the harassment score, the more frequent the disordered eating behavior symptoms, even after adjusting for age and previous sexual violence. The association was stronger for males than females. Sexual harassment and disordered eating behaviors have long been considered mainly a female problem. Men are not exempt from these problems and in some cases may be more affected than women. The topics should be assessed in men and women.

  17. MicroRNA responses to focal cerebral ischemia in male and female mouse brain

    Full Text Available Stroke occurs with greater frequency in men than in women across diverse ethnic backgrounds and nationalities. Work from our lab and others have revealed a sex-specific sensitivity to cerebral ischemia whereby males exhibit a larger extent of brain damage resulting from an ischemic event compared to females. Previous studies revealed that microRNA (miRNA expression is regulated by cerebral ischemia in males; however, no studies to date have examined the effect of ischemia on miRNA responses in females. Thus, we examined miRNA responses in male and female brain in response to cerebral ischemia using miRNA arrays. These studies revealed that in male and female brains, ischemia leads to both a universal miRNA response as well as a sexually distinct response to challenge. Target prediction analysis of the miRNAs increased in male or female ischemic brain reveal sex-specific differences in gene targets and protein pathways. These data support that the mechanisms underlying sexually dimorphic responses to cerebral ischemia includes distinct changes in miRNAs in male and female brain, in addition to a miRNA signature response to ischemia that is common to both.

    The purpose of this study was to explore male and female adolescents' perceptions of and differences in Event History Calendar (EHC) sexual risk assessment in a clinical setting. This study is a secondary analysis exploring male and female qualitative data from a mixed methods study of adolescent and provider communication. Participants included 30 sexually active 15- to 19-year-old male (n = 11) and female (n = 19) patients at a school-linked clinic. The adolescents completed a pre-clinic visit EHC and then discussed it with a nurse practitioner during their visit. The adolescents shared their perceptions of the EHCs in a post-clinic visit interview. Constant comparative analyses revealed gender differences in: (a) adolescents' perceptions of how EHCs helped report, reflect on, and discuss sexual risk histories; (b) how adolescents self-administered EHCs; and (c) the histories they reported. The EHC was well received by both male and female adolescents, resulting in a more complete sexual risk history disclosure. Self-administration of the EHC is recommended for all adolescents, but further sexual risk assessment by nurse practitioners who use EHCs is needed.

    Full Text Available Uterine fibroids are a common problem in women. Statistics showing 20–50% of fibroids produce symptoms and consequently patients seek surgical intervention to improve their quality of life. Treatments for fibroids are typically successful in controlling the fibroid disease, yet sexual function following invasive surgical treatments for fibroids can be jeopardized. The Sexual Function Index (FSFI is a valid instrument producing quantifiable reproducible results. In this paper three case reports are evaluated by the FSFI and compared between the following treatment groups: hysterectomy, myomectomy, and uterine embolization. Our goal is to illustrate how each of these treatment outcomes can result in sexual dysfunction and therefore decreased quality of life. Effects of invasive fibroid treatments on sexual functioning would be helpful in guiding patient’s ultimate decisions regarding treatment.

    To get information in the sexual and contraceptive behaviors in Chinese female college students, a randomized cluster sampling was conducted in colleges and universities in Wuhan Area,China, in terms of types of colleges, subjects (literature, sciences, medicines, art etc), and grades etc.A total number of 2450 questionnaires were distributed, with 2365 questionnaires returned being valid. The return rate of valid questionnaires was 96.6%. The questionnaire investigation was conducted on a multiple-choice and anonymous basis. Data were input into computer and SPSS12.0software package was employed for statistical analysis. Among the female students, 1196 had the experiences of hugging and kissing (50.57%) and 423 (17.89%) had sexual experiences (sexual intercourse). The first sexual intercourse took place at the age of 19.23±1.74 y. There were significant differences in the sexual experiences among the majors of different subjects, with the rate of sexual experiences in art majors (43.17%) and high-grade students (34.31%) being the highest. The causes of the first sexual intercourse included sexual impulse, curiosity, intention to strengthen the relationship or to show loyalty to boyfriend and sometimes violence. While the motives of the sexual intercourse within the past one year before the investigation were to satisfy the sexual needs and to strengthen the relation with their boyfriends. With both first intercourse and sexual experiences within last one year,the partners of the sexual intercourse were mainly their boyfriends (95.7% and 97.3% respectively),but the partners also included acquaintances, "one night stand" partners and customers of sex trade.Some of them had multiple sexual partners, with the highest number of the sexual partners being 11.In the first sexual intercourse of the subjects, 44.0% of them did not take any contraceptive measures;only 16.4 % of them used condoms. In the sexual intercourse within the last one year, only 44.6%took

  3. Infanticide as sexual conflict: coevolution of male strategies and female counterstrategies.

    Palombit, Ryne A

    2015-05-18

    One of the earliest recognized forms of sexual conflict was infanticide by males, which imposes serious costs on female reproductive success. Here I review two bodies of evidence addressing coevolved strategies of males and females. The original sexual selection hypothesis arguing that infanticide improves male mating success by accelerating the return of females to fertilizable condition has been generally supported in some taxa--notably, some primates, carnivores, rodents, and cetaceans--but not in other taxa. One result of recent research has been to implicate other selective benefits of infanticide by males in various taxa from insects to birds to mammals, such as acquisition of breeding status or improvement of the female breeding condition. In some cases, however, the adaptive significance of male infanticide remains obscure. The second body of data I review is arguably the most important result of recent research: clarifying the possible female counterstrategies to infanticide. These potential counterstrategies span diverse biological systems, ranging from sexual behavior (e.g., polyandrous mating), to physiology (e.g., the Bruce effect), to individual behavior (e.g., maternal aggression), to social strategies (e.g., association with coalitionary defenders of either sex). Although much remains to be studied, these current data provide compelling evidence of sexually antagonistic coevolution surrounding the phenomenon of infanticide.

    Evidence on the prevalence of sexual aggression among college students is primarily based on studies from Western countries. In Chile, a South American country strongly influenced by the Catholic Church, little research on sexual aggression among college students is available. Therefore, the purpose of the present study was to examine the prevalence of sexual aggression victimization and perpetration since the age of 14 (the legal age of consent) in a sample of male and female students aged between 18 and 29 years from five Chilean universities (N = 1135), to consider possible gender differences, and to study the extent to which alcohol was involved in the reported incidents of perpetration and victimization. Sexual aggression victimization and perpetration was measured with a Chilean Spanish version of the Sexual Aggression and Victimization Scale (SAV-S), which includes three coercive strategies (use or threat of physical force, exploitation of an incapacitated state, and verbal pressure), three victim-perpetrator constellations (current or former partners, friends/acquaintances, and strangers), and four sexual acts (sexual touch, attempted sexual intercourse, completed sexual intercourse, and other sexual acts, such as oral sex). Overall, 51.9% of women and 48.0% of men reported at least one incident of sexual victimization, and 26.8% of men and 16.5% of women reported at least one incident of sexual aggression perpetration since the age of 14. For victimization, only few gender differences were found, but significantly more men than women reported sexual aggression perpetration. A large proportion of perpetrators also reported victimization experiences. Regarding victim-perpetrator relationship, sexual aggression victimization and perpetration were more common between persons who knew each other than between strangers. Alcohol use by the perpetrator, victim, or both was involved in many incidents of sexual aggression victimization and perpetration, particularly

    To assess whether the current condition-specific sexual function questionnaire provides full insight into sexual function following pelvic floor surgery. Prospective, mixed quantitative and qualitative study. Urogynaecology clinic in a large university hospital. Thirty-seven women undergoing surgery for pelvic organ prolapse (POP) and/or stress urinary incontinence (SUI). Women were seen before surgery and 3 months postoperatively. At both visits the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ) was completed and a qualitative face-to-face semi-structured interview was conducted. PISQ total and domain scores, as well as the change in the preoperative and postoperative score, were calculated and analysed using Wilcoxon signed rank test and one-sample t-test. The qualitative data were systematically analysed using data-matrices. The impact of pelvic floor surgery on female sexual function. Significant improvement was seen for PISQ total score (P = 0.003) as well as Physical (P qualitative data showed that improvement in sexual function was a result of cure of POP and SUI symptoms. Deterioration of sexual function was due to dyspareunia, fear of causing damage to the surgical result, new symptoms and a disappointing result of surgery. Our qualitative data show that PISQ is limited in the assessment of sexual function after pelvic floor surgery as it does not assess most surgery-specific negative effects on sexual function. © 2013 Royal College of Obstetricians and Gynaecologists.

    Female sexual function is negatively influenced by pregnancy due to the physical and emotional changes. Although the most significant effect is seen in the third trimester of pregnancy, a considerable decrease in the frequency of intercourse and sexual desire in the first trimester has also been shown. To investigate the factors that affect sexuality in early pregnancy and the impact of awareness of pregnancy on female sexual function in the first trimester of pregnancy using two self-reported questionnaires. In this cross-sectional study, 130 healthy, married pregnant women who were admitted to the gynecology clinic between the 4th and 10th week of gestation were asked to complete a self-administered questionnaire and the female sexual function index (FSFI). The factors associated with FSFI score and monthly sexual activity frequency in the first trimester, as well as the differences in sexual activity frequency and FSFI scores between the women who were previously aware of their pregnancy and those who were yet unaware of their pregnancy. Women who were unaware of their pregnancy had significantly higher coitus frequency in comparison with the aware group (P = 0.002). Total FSFI score was 21.99 ± 8.13 in the aware group and 24.66 ± 3.76 in the unaware group (P = 0.02). None of the obstetric and sociodemographic variables had an influence on desire and pain scores. Arousal, lubrication, and satisfaction scores were adversely affected by awareness of pregnancy. Orgasm scores were influenced negatively by awareness and positively by love marriage; however, in multivariate linear regression analysis none of these were defined as independent factor for orgasm scores. Overall FSFI scores and monthly frequency of sexual activity were only affected by awareness. The results of this study suggest that in early gestation, awareness of pregnancy is associated with lower female sexual function. Furthermore, obstetric and sociodemographic factors seem to be

    The aim of this study was to estimate the level of knowledge about sexuality, attitudes and sexual behaviour of female adolescents. The study included 194 female students, 117 from Medical High School (MHS) and 77 from General High School (GHS) in Zagreb. Data was collected using an anonymous self-administered questionnaire. In addition to items on personal data (age, parental education etc.), the participants were asked to define terms about sexuality (e.g. menstruation, puberty) the definitions of which are found in biology textbooks for the fifth and eighth grade of primary school. The aim of the third part of the survey was to collect information about attitudes and behaviour of female adolescents. The results showed a low level of knowledge in students of both schools. General High School students showed a higher level of knowledge than their Medical High School peers. One fifth of General High School students and 1/3 of Medical High School students were unable to define the term "menstruation". The majority of adolescents talk about sexuality with their friends, 92.1% of General High School and 81.2% of Medical High School students. Almost 50% of students of both schools would like to talk about sexuality with their school doctor. 6.9% of Medical High School students had at least one sexual intercourse while none of the General High School students had been sexually active at the time of the survey. As the majority of students were not sexually active and results showed a rather low level of knowledge, this seems to be the ideal period for the implementation of educational programs aimed at increasing the level of knowledge, and thus preventing unwanted consequences (STD, pregnancy, abortion, infertility).

    Full Text Available Obesity and gestational diabetes mellitus (GDM are increasing worldwide and may compromise female sexual function. We hypothesize that among GDM patients in the third trimester of pregnancy, those with excess body fat would have worse female sexual function scores than normal weight women. Our aim was to assess the sexual function of overweight compared to normal weight women with GDM. This was a cross-sectional survey involving 143 Brazilian women with GDM in the third trimester of pregnancy: 76 were overweight (pre-pregnancy body mass index-BMI≥25.0 Kg/m2 and 67 were normal weight (BMI 18.5-24.9 Kg/m2. Participants were recruited from March 2010 to April 2013 at the antenatal clinic of a single public tertiary teaching institution. The Female Sexual Function Index (FSFI questionnaire was used to assess sexual function. Overall, 51.7% of the 143 participants were at risk for sexual dysfunction symptoms (FSFI scores ≤26; this rate was significantly higher among overweight compared to normal weight women (60.5% versus 41.8%, p = 0.038. Mean total FSFI scores were significantly lower in overweight compared to normal weight women (21.7±9.2 versus 24.9±8.0, p = 0.029. Compared to normal weight women, overweight participants had lower mean scores in desire (3.4±1.2 versus 4.0±1.4, p = 0.007 and lubrication (3.8±2.0 versus 4.5±1.6, p = 0.023. According to these results, overweight women with GDM in the third trimester of pregnancy have lower female sexual function scores than normal weight women with the same disorder.

    This study explored the relationship between the involvement of biological fathers and the sexual risk behaviors and dating violence/victimization and/or perpetration of adolescent girls. The data used in this cross-sectional analysis were drawn from the second wave of the public release of the National Longitudinal Study of Adolescent Health. Only adolescents who reported their biological sex as female, reported a history of being sexually active, and reported having a romantic partner in the previous 18 months were selected (N = 879). This study focused on overall positive sexual behaviors and use of contraception. Structural equation modeling (SEM) was used to best utilize capacity for dealing with latent variables and to test for possible mediation effects. The analysis demonstrated main effects of dating violence and father involvement on sexual behaviors. The more dating violence an adolescent girl experiences, the less likely she is to engage in healthy sexual behaviors. Likewise, the more involvement the biological father has in a woman's life, the more likely she is to engage in positive sexual behaviors. Perceived father involvement was associated with risky sexual behaviors among sexually experienced adolescent girls. Dating violence was directly associated with risky sexual behaviors among sexually experienced adolescent girls, particularly non-White girls. Future studies should use longitudinal models and test theoretically and empirically guided potential mediators. Future studies should also consider father figures such as step-fathers and grandfathers in addition to biological fathers, as having a father figure may be a stronger predictor of adolescent sexual behaviors than having a biological connection.

    The global literature suggests that female sex workers (FSWs) experience high rates of sexual violence perpetrated by their clients, especially when FSWs are under the influence of alcohol. However, such data are limited in China. The current study is aimed to fill in the literature gap by examining the association between alcohol use by FSWs and client-perpetrated sexual violence against FSWs in China. A total of 1022 FSWs were recruited through community outreach in Guangxi, China. Female sex workers completed a self-administered survey on their demographic information, alcohol use, and sexual violence perpetrated by clients. Multivariable regression was employed to assess the relationship between alcohol use and client-perpetrated sexual violence among FSWs while controlling for possible confounders. Results indicated that alcohol use was positively associated with the experience of sexual violence in both bivariate and multivariable analyses. Women who were at a higher risk level of alcohol use were more likely to experience sexual violence perpetrated by clients even after controlling confounders (e.g., demographics and alcohol-serving practice). Given the association between alcohol use and client-perpetrated sexual violence, preventing or reducing alcohol use among FSWs could be an effective strategy to protect these women from sexual violence perpetrated by their clients. Alternatively, psychological counseling and other support should be available to these women so they can reduce their alcohol use as a maladaptive coping strategy. We call for culturally appropriate alcohol use reduction components, incorporated with sexual violence reduction strategies including adaptive coping skills training as well as empowerment, and targeting both FSWs and their clients.

  12. The nutritional and hedonic value of food modulate sexual receptivity in Drosophila melanogaster females.

    Food and sex often go hand in hand because of the nutritional cost of reproduction. For Drosophila melanogaster females, this relationship is especially intimate because their offspring develop on food. Since yeast and sugars are important nutritional pillars for Drosophila, availability of these foods should inform female reproductive behaviours. Yet mechanisms coupling food and sex are poorly understood. Here we show that yeast increases female sexual receptivity through interaction between its protein content and its odorous fermentation product acetic acid, sensed by the Ionotropic odorant receptor neuron Ir75a. A similar interaction between nutritional and hedonic value applies to sugars where taste and caloric value only increase sexual receptivity when combined. Integration of nutritional and sensory values would ensure that there are sufficient internal nutrients for egg production as well as sufficient environmental nutrients for offspring survival. These findings provide mechanisms through which females may maximize reproductive output in changing environments.

    Social support can affect health outcomes of female sex workers. In this inductive feminist grounded theory study based on 20 in-depth interviews, we explore how establishment-based female sex workers in Tijuana perceive the impact of the connections among women on their lives and health. Participants elected to discuss the importance of social support from mothers, sisters, friends, and co-workers, and the empowering and disempowering aspects of these relationships. In previous studies, scholars demonstrated the efficacy of formal organization of female sex workers in promoting the mitigation of sexual and HIV risk. We show the importance of informal ties with other women. Some participants mentioned competitive relationships, others talked about cooperation and the desire for a venue to learn from one another. Social interactions with other women are especially empowering when female sex workers can openly engage in "woman talk" that may contribute to the mitigation of sexual and HIV risk.

  15. Males Resemble Females: Re-Evaluating Sexual Dimorphism in Protoceratops andrewsi (Neoceratopsia, Protoceratopsidae.

    Leonardo Maiorino

    Full Text Available Protoceratops andrewsi (Neoceratopsia, Protoceratopsidae is a well-known dinosaur from the Upper Cretaceous of Mongolia. Some previous workers hypothesized sexual dimorphism in the cranial shape of this taxon, using qualitative and quantitative observations. In particular, width and height of the frill as well as the development of a nasal horn have been hypothesized as potentially sexually dimorphic.Here, we reassess potential sexual dimorphism in skulls of Protoceratops andrewsi by applying two-dimensional geometric morphometrics to 29 skulls in lateral and dorsal views. Principal Component Analyses and nonparametric MANOVAs recover no clear separation between hypothetical "males" and "females" within the overall morphospace. Males and females thus possess similar overall cranial morphologies. No differences in size between "males" and "females" are recovered using nonparametric ANOVAs.Sexual dimorphism within Protoceratops andrewsi is not strongly supported by our results, as previously proposed by several authors. Anatomical traits such as height and width of the frill, and skull size thus may not be sexually dimorphic. Based on PCA for a data set focusing on the rostrum and associated ANOVA results, nasal horn height is the only feature with potential dimorphism. As a whole, most purported dimorphic variation is probably primarily the result of ontogenetic cranial shape changes as well as intraspecific cranial variation independent of sex.

    Full Text Available Gender differences in perceptions of sexual intent and commitment have been the subject of formal and informal inquiry for considerable time. One evolutionary theory, Error Management Theory (EMT, predicts that opposite-sex perceptions of female sexual intent and male commitment intent reflect intrinsic biases that minimize gender-specific evolutionary costs. The results supporting these hypotheses were obtained from subjects regardless of mood. We hypothesized that mood would influence ratings of sexual and commitment intent. Sixty participants (30 males, 30 females were recruited and exposed to a positive and negative mood condition in counterbalanced groups using video stimuli. Preliminary analyses found an unexpected effect of order of mood induction, necessitating separate analyses of the Positive-Negative (PN and Negative-Positive (NP groups. Contrary to the original study, there were no gender effects. Positive moods led to increased ratings of both sexual and commitment intent across genders. Further, negative to positive mood-change was associated with significantly increased ratings. Both males and females attributed significantly higher sexual intent to same-sex rivals than themselves, but only males assessed themselves as having significantly higher commitment intent than same-sex rivals. The EMT model may require adaptation to acknowledge effects of variables such as mood on its predictions of gender-specific biases.

    Full Text Available Sexual violence against females is a public health problem. This descriptive cross-sectional study sought to determine the prevalence of sexual violence among out-of-school female adolescents in Lagos, Nigeria and examine the context in which it occurs. Three hundred and fifty adolescents, between the ages of 10 and 19 years, working in Sandgrouse market, Lagos, were selected using cluster sampling. Data were collected using an interviewer-administered questionnaire. Almost half (42.9% of the respondents have had sexual intercourse, and median age at initiation was 17 years. Forced initiation was reported by 15.8%, and 36.3% reported that first intercourse was due to coercion. Among the sexually active, only 12.3% stated that “it is what they desire.” Majority of respondents (64.1% believe that rape is common in their community, and 18% of the sexually active have experienced rape. Out-of-school adolescents in this community are at risk of sexual violence. The factors that make them vulnerable need to be addressed.

  18. The ontogeny of sexual size dimorphism of a moth: when do males and females grow apart?

    Directory of Open Access Journals (Sweden)

    R Craig Stillwell

    Full Text Available Sexual dimorphism in body size (sexual size dimorphism is common in many species. The sources of selection that generate the independent evolution of adult male and female size have been investigated extensively by evolutionary biologists, but how and when females and males grow apart during ontogeny is poorly understood. Here we use the hawkmoth, Manduca sexta, to examine when sexual size dimorphism arises by measuring body mass every day during development. We further investigated whether environmental variables influence the ontogeny of sexual size dimorphism by raising moths on three different diet qualities (poor, medium and high. We found that size dimorphism arose during early larval development on the highest quality food treatment but it arose late in larval development when raised on the medium quality food. This female-biased dimorphism (females larger increased substantially from the pupal-to-adult stage in both treatments, a pattern that appears to be common in Lepidopterans. Although dimorphism appeared in a few stages when individuals were raised on the poorest quality diet, it did not persist such that male and female adults were the same size. This demonstrates that the environmental conditions that insects are raised in can affect the growth trajectories of males and females differently and thus when dimorphism arises or disappears during development. We conclude that the development of sexual size dimorphism in M. sexta occurs during larval development and continues to accumulate during the pupal/adult stages, and that environmental variables such as diet quality can influence patterns of dimorphism in adults.

    Full Text Available Background: Sexual dysfunction (SD is a known adverse effect of psychotropic medications. Even though sexual difficulties are common among women; very few studies have been carried out in India. Objective: To study the prevalence and nature of SD among females receiving psychotropic medications and to compare the SD among female patients receiving antipsychotics and antidepressants. Materials and Methods: Female investigator conducted a hospital-based cross-sectional study on female patients visiting the psychiatry outpatient department. Patients meeting inclusion criteria were assessed for SD disorder as per Diagnostic and Statistical Manual of Mental Disorders 4th Edition Text Revision. SD severity was measured using Female Sexual Function Index (FSFI scale. Results: The prevalence of SD in this study was 68.32%. There was more than one SD in 48 (47.52%. FSFI score was significantly low in patients with SD as compared to patients not having SD (P = 0.001. SD was more common in patients who were on combination of antidepressants and benzodiazepines than antidepressant alone or antipsychotic alone. Conclusion: SD was prevalent in more than 50% of female patients on psychotropic drugs. Number of patients on individual psychotropic drugs was so small that a definite conclusion could not be drawn. Study emphasizes the need to carry out similar study on larger number of patients to get better insight into this problem.

    Intraspecific male-male aggression, which is important for sexual selection, is regulated by environment, experience and internal states through largely undefined molecular and cellular mechanisms. To understand the basic neural pathway underlying the modulation of this innate behavior, we established a behavioral assay in Drosophila melanogaster and investigated the relationship between sexual experience and aggression. In the presence of mating partners, adult male flies exhibited elevated levels of aggression, which was largely suppressed by prior exposure to females via a sexually dimorphic neural mechanism. The suppression involved the ability of male flies to detect females by contact chemosensation through the pheromone-sensing ion channel ppk29 and was mediated by male-specific GABAergic neurons acting on the GABAA receptor RDL in target cells. Silencing or activating this circuit led to dis-inhibition or elimination of sex-related aggression, respectively. We propose that the GABAergic inhibition represents a critical cellular mechanism that enables prior experience to modulate aggression.

    Female reproductive potential plays a significant role in the survival and stability of species, and sexual maturation and mating processes are crucial. However, our knowledge of the reproductive genes involved in sexual maturation and mating has been largely limited to model organisms. The oriental fruit fly Bactrocera dorsalis is a highly invasive agricultural pest, known to cause major economic losses; thus, it is of great value to understand the transcriptional changes involved in sexual maturation and mating processes as well as the related genes. Here, we used a high-throughput sequencing method to identify multiple genes potentially involved in sexual maturation and mating in female B. dorsalis. We sequenced 39,999 unique genes with an average length of 883 bp. In total, 3264 differentially expressed genes (DEGs) were detected between mature virgin and immature Bactrocera dorsalis libraries, whereas only 83 DEGs were identified between flies that had mated or were mature virgins. These DEGs were functionally annotated using the GO and KEGG pathway annotation tools. Results showed that the main GO terms associated with the DEGs from the mature virgin vs. immature groups were primarily assigned to the metabolic and developmental processes, which we focused on, whereas those from the mated vs. mature virgin group largely belonged to the response to stimulus and immune system processes. Additionally, we identified multiple DEGs during sexual maturation that are involved in reproduction, and expression pattern analysis revealed that the majority DEGs detected were highly enriched in those linked to the ovaries or fat bodies. Several mating responsive genes differentially expressed after mating were also identified, and all antimicrobial peptides detected were highly enriched in fat body and significantly up-regulated approximately 2- to 10-fold at 24 h after mating. This study supplied female reproductive genes involved in sexual maturation and the post

    In many species of animals, individuals advertise their quality with sexual signals to obtain mates. Chemical signals such as volatile pheromones are species specific, and their primary purpose is to influence mate choice by carrying information about the phenotypic and genetic quality of the sender. The deleterious effects of consanguineous mating on individual quality are generally known, whereas the effect of inbreeding on sexual signalling is poorly understood. Here, we tested whether inbreeding reduces the attractiveness of sexual signalling in the mealworm beetle, Tenebrio molitor, by testing the preferences for odours of inbred and outbred (control) individuals of the opposite sex. Females were more attracted to the odours produced by outbred males than the odours produced by inbred males, suggesting that inbreeding reduces the attractiveness of male sexual signalling. However, we did not find any difference between the attractiveness of inbred and outbred female odours, which may indicate that the quality of females is either irrelevant for T. molitor males or quality is not revealed through female odours.

    Female sexual function is a difficult entity to be assessed. Subjective factors and interview biases can change the perception of it. Using validated questionnaires can improve the scientific approach to this matter. There is a huge difference of severity and incidence among young, apparent healthy women, which are in a harmonious relationship. We evaluated 320 healthy women, with stable sexual active relationship, with no know depressive disease, endocrinological and metabolic pathology, no premature menopause, no malignancy. We compose a mathematic model to study the impact of age, and body weight on the sexual function, with FSFI total score as surrogate marker. We observed that even in healthy women, increase in age and/or weight/body mass significantly impair general sexual function.

    2015-03-01

    This study aims to explore the association between early sex initiation and subsequent unsafe sexual behaviors and risks among Chinese female undergraduates. Of 4769 participants, 863 (18.1%) reported ever having sexual intercourse. The mean age of sexual debut was 19.3 (±1.7) years. Females initiating sex earlier were more likely to have first sex with men who were not their "boyfriends" and less likely to take contraception, to use a condom at first encounter, to use contraception consistently in past year, and/or to use condom consistently during the course of a sexual intercourse. They were more likely to have multiple lifetime and concurrent sexual partners, to report pregnancy, and be diagnosed with sexually transmitted diseases. Comprehensive early sex education should be advocated for young people, not only teaching knowledge of physical health but also providing practical skills training for making them consciously delay start of sexual activity or protecting themselves during sexual intercourse.

    Purpose Child sexual abuse and sexual dating violence victimization are common problems that are known to have long-term negative consequences. This study aimed to compare the sociodemographic, abuse-related, and clinical features of female adolescents who were sexually abused by different perpetrators, and identify the factors associated with suicidality and nonsuicidal self-injury (NSSI) in these cases. Patients and methods Data of 254 sexually abused female adolescents between the ages of 12–18 years were evaluated. The cases were classified into three groups, namely “sexual dating violence”, “incest”, and “other child sexual abuse”, according to the identity of the perpetrator. The three groups were compared in terms of sociodemographic, abuse-related, and clinical features. Results Major depressive disorder was the most common psychiatric diagnosis, which was present in 44.9% of the cases. Among all victims, 25.6% had attempted suicide, 52.0% had suicidal ideation, and 23.6% had NSSI during the postabuse period. A logistic regression analysis revealed that attempted suicide was predicted by dating violence victimization (adjusted odds ratio [AOR] =3.053; 95% confidence interval [CI] =1.473, 6.330) and depression (AOR =2.238; 95% CI =1.226, 4.086). Dating violence victimization was also the strongest predictor of subsequent suicidal ideation (AOR =3.500; 95% CI =1.817, 6.741). In addition, revictimization was determined to be an important risk factor for both suicidal ideation (AOR =2.897; 95% CI =1.276, 6.574) and NSSI (AOR =3.847; 95% CI =1.899, 7.794). Conclusion Perpetrator identity and revictimization are associated with negative mental health outcomes in sexually victimized female adolescents. Increased risk of suicidality and NSSI should be borne in mind while assessing cases with dating violence and revictimization histories, in particular. PMID:27382291

    Agency attribution is a hallmark of mind perception; thus, diminished attributions of agency may disrupt social-cognition processes typically elicited by human targets. The current studies examine the effect of perceivers' sexist attitudes on associations of agency with, and neural responses to, images of sexualized and clothed men and women. In Study 1, male (but not female) participants with higher hostile sexism scores more quickly associated sexualized women with first-person action verbs ("handle") and clothed women with third-person action verbs ("handles") than the inverse, as compared to their less sexist peers. In Study 2, hostile sexism correlated negatively with activation of regions associated with mental state attribution-medial prefrontal cortex, posterior cingulate, temporal poles-but only when viewing sexualized women. Heterosexual men best recognized images of sexualized female bodies (but not faces), as compared with other targets' bodies; however, neither face nor body recognition was related to hostile sexism, suggesting that the fMRI findings are not explained by more or less attention to sexualized female targets. Diminished mental state attribution is not unique to targets that people prefer to avoid, as in dehumanization of stigmatized people. The current studies demonstrate that appetitive social targets may elicit a similar response depending on perceivers' attitudes toward them.

    High rates of adolescent pregnancy, sexually transmitted infections, and unsafe abortions in Nigeria indicate the need for a greater understanding of factors that affect adolescent sexuality. The sexual health needs of adolescents remain poorly known and addressed particularly among vulnerable subpopulations like out-of-school adolescents. The objective of this study was to examine the sexual behavior of female out-of-school adolescents and to identify factors that influence their sexual behavior. This cross-sectional study was conducted among a representative sample of unmarried, out-of-school female adolescents (n = 332, mean age 17 y), selected using cluster sampling, who were working in a major market (Mushin) in Lagos, Nigeria. Data were collected using interviewer administered questionnaires. Many girls (43.7%) have had sexual intercourse. The mean age at initiation was 16 years. The main reason for initiation was curiosity. Risky sexual behavior and transactional sex was common. Nonconsensual sex was also reported. Sexual health knowledge was poor, and friends served as their main source of information on sexual health issues. Factors associated with the initiation of sexual activity were friends sexual behavior, the person adolescents reside with, parents marital status, availability of funds to meet basic needs, and watching pornography (p sexual behavior are exposed to sexual abuse, lack skills to resist pressure, and have limited access to credible reproductive health information. Appropriate interventions including provision of sexuality education and a supportive environment must be instituted to address their needs.

  19. Insulin-producing cells regulate the sexual receptivity through the painless TRP channel in Drosophila virgin females.

    Directory of Open Access Journals (Sweden)

    Takaomi Sakai

    Full Text Available In a variety of animal species, females hold a leading position in evaluating potential mating partners. The decision of virgin females to accept or reject a courting male is one of the most critical steps for mating success. In the fruitfly Drosophila melanogaster, however, the molecular and neuronal mechanisms underlying female receptivity are still poorly understood, particularly for virgin females. The Drosophila painless (pain gene encodes a transient receptor potential (TRP ion channel. We previously demonstrated that mutations in pain significantly enhance the sexual receptivity of virgin females and that pain expression in pain(GAL4 -positive neurons is necessary and sufficient for pain-mediated regulation of the virgin receptivity. Among the pain(GAL4 -positive neurons in the adult female brain, here we have found that insulin-producing cells (IPCs, a neuronal subset in the pars intercerebralis, are essential in virgin females for the regulation of sexual receptivity through Pain TRP channels. IPC-specific knockdown of pain expression or IPC ablation strongly enhanced female sexual receptivity as was observed in pain mutant females. When pain expression or neuronal activity was conditionally suppressed in adult IPCs, female sexual receptivity was similarly enhanced. Furthermore, both pain mutations and the conditional knockdown of pain expression in IPCs depressed female rejection behaviors toward courting males. Taken together, our results indicate that the Pain TRP channel in IPCs plays an important role in controlling the sexual receptivity of Drosophila virgin females by positively regulating female rejection behaviors during courtship.

    Trauma from female incestuous child sexual abuse may result in negative psychological consequences affecting adult relationships. This study explored relational consequences of incestuous child sexual abuse, focusing on conflict resolution styles, relationship satisfaction, and relationship stability. Using the RELATionship Evaluation dataset, 457 heterosexual couples in which female partners experienced incestuous child sexual abuse were compared to a group of 1,827 couples with no sexual abuse history. Analyses tested differences in the frequencies of reported conflict resolution styles for incestuous child sexual abuse and non-incestuous child sexual abuse groups, the mediating effects of conflict resolution styles on the relationship between incestuous child sexual abuse, and self- and partner-reported relationship satisfaction and stability. Significant differences in the reports of types of conflict resolution styles were found for incestuous child sexual abuse versus non-incestuous child sexual abuse groups. Incestuous child sexual abuse and conflict resolution styles were negatively related to relationship satisfaction and stability and there was a significant indirect effect between female incestuous child sexual abuse, female volatility, and relationship instability. Clinical applications for couple relationships are discussed.

    Among 284 African American girls aged 14 to 17 years, frequent family monitoring knowledge was associated with a reduced likelihood of sexually transmitted infections (STIs) and having a casual sex partner but was not associated with other partnership characteristics. Family monitoring may offer an additional STI prevention opportunity for this vulnerable population.

  2. Incipient sexual isolation in Laupala cerasina: Females discriminate population-level divergence in acoustic characters

    2012-06-01

    Full Text Available Sexual selection by female choice can shape the evolution of male traits within populations, since the most attractive males experience an increase in fitness through elevated mating success. Speciation by sexual selection occurs when evolution in traits and preferences within populations causes differentiation among populations, such that females in alternative populations prefer sexual signals of their own population relative to others. Differentiated traits and preferences thereby play an active role in limiting gene flow between divergent populations. The effectiveness of differentiated preferences in maintaining differentiated male signals against the homogenizing effects of gene flow across populations will be limited by both the degree to which females can discriminate against non-local males, and the breeding values of traits and preferences. Populations of the Hawaiian cricket Laupala cerasina have diverged in pulse rate, a sexually selected male signal, and female acoustic preference for pulse rate. Gene flow between neighboring populations may be reduced if migrants from sexually diverged populations experience reduced mating success. We show that females discriminate among divergent songs characteristic of neighboring populations, that diffe­rences among populations in song and preference breed true in a common environment, and that mean preferences for each population closely match the mean pulse rates. Divergence in preference was observed only between populations that also differed in song. Along with a striking ability to discriminate slight differences in song, correlated evolution of song and preference within populations could be a mechanism that promotes assortative mating among populations, thereby reducing gene flow, and leading to speciation in Laupala [Current Zoology 58 (3: 416-425, 2012].

    Sexual selection by female choice can shape the evolution of male traits within populations,since the most attractive males experience an increase in fitness through elevated mating success.Speciation by sexual selection occurs when evolution in traits and preferences within populations causes differentiation among populations,such that females in alternative populations prefer sexual signals of their own population relative to others.Differentiated traits and preferences thereby play an active role in limiting gene flow between divergent populations.The effectiveness of differentiawel preferences in maintaining differentiated male signals against the homogenizing effects of gene flow across populations will be limited by both the degree to which females can discriminate against non-local males,and the breeding values of traits and preferences.Populations of the Hawaiian cricket Laupala cerasina have diverged in pulse rate,a sexually selected male signal,and female acoustic preference for pulse rate.Gene flow between neighboring populations may be reduced if migrants from sexually diverged populations experience reduced mating success.We show that females discriminate among divergent songs characteristic of neighboring populations,that differences among populations in song and preference breed true in a common environment,and that mean preferences for each population closely match the mean pulse rates.Divergence in preference was observed only between populations that also differed in song.Along with a striking ability to discriminate slight differences in song,correlated evolution of song and preference within populations could be a mechanism that promotes assortative mating among populations,thereby reducing gene flow,and leading to speciation in Laupala.

    Understanding the patterns of genetic variation of traits subject to sexual selection is fundamental for explaining its evolutionary dynamics and potential for sexual coevolution. The signa of female Lepidoptera are sclerotized structures located on the inner surface of the genital receptacle that receives the spermatophore during copulation (the corpus bursae), whose main function is tearing the spermatophore envelope. Comparative data indicate that the evolution of signa has been influenced by sexually antagonistic coevolution with spermatophore envelopes. We looked for additive genetic variation in the size and shape of signa in females of the butterfly Callophrys xami (Lycaenidae) from two localities (BG and FC) in Mexico City. We also looked for genetic variation in female body size and in the size of corpus bursae. There were significant between-population differences in female body size, signa width and three signa shape traits. We found significant extranuclear maternal effects in one component of signa shape in the BG population, and in body weight, signa length and in one uniform component of signa shape in the FC population. Extranuclear maternal contributions could permit the evolution of female adaptations even if these reduce male fitness. We found additive genetic variation in signa length and width only in one population (BG); heritability estimates were high: 0.96 and 0.8, respectively. The existence of additive genetic variation in signa size could be, at least in part, a result of relaxed sexually antagonistic selection pressures due to the low level of polyandry exhibited by this species. Our results imply that there is currently potential for further sexual coevolution in this trait.

  5. Sexual signalling in female crested macaques and the evolution of primate fertility signals

    Full Text Available Abstract Background Female signals of fertility have evolved in diverse taxa. Among the most interesting study systems are those of multimale multifemale group-living primates, where females signal fertility to males through multiple signals, and in which there is substantial inter-specific variation in the composition and reliability of such signals. Among the macaques, some species display reliable behavioural and/or anogenital signals while others do not. One cause of this variation may be differences in male competitive regimes: some species show marked sexual dimorphism and reproductive skew, with males fighting for dominance, while others show low dimorphism and skew, with males queuing for dominance. As such, there is variation in the extent to which rank is a reliable proxy for male competitiveness, which may affect the extent to which it is in females’ interest to signal ovulation reliably. However, data on ovulatory signals are absent from species at one end of the macaque continuum, where selection has led to high sexual dimorphism and male reproductive skew. Here we present data from 31 cycles of 19 wild female crested macaques, a highly sexually dimorphic species with strong mating skew. We collected measures of ovarian hormone data from faeces, sexual swelling size from digital images, and male and female behaviour. Results We show that both sexual swelling size and female proceptivity are graded-signals, but relatively reliable indicators of ovulation, with swelling size largest and female proceptive behaviours most frequent around ovulation. Sexual swelling size was also larger in conceptive cycles. Male mating behaviour was well timed to female ovulation, suggesting that males had accurate information about this. Conclusion Though probabilistic, crested macaque ovulatory signals are relatively reliable. We argue that in species where males fight over dominance, male dominance rank is surrogate for competitiveness. Under these

  6. The evolution of a female genital trait widely distributed in the Lepidoptera: comparative evidence for an effect of sexual coevolution.

    Full Text Available BACKGROUND: Sexual coevolution is considered responsible for the evolution of many male genital traits, but its effect on female genital morphology is poorly understood. In many lepidopterans, females become temporarily unreceptive after mating and the length of this refractory period is inversely related to the amount of spermatophore remaining in their genital tracts. Sperm competition can select for males that delay female remating by transferring spermatophores with thick spermatophore envelopes that take more time to be broken. These envelopes could select for signa, sclerotized sharp structures located within the female genital tract, that are used for breaking spermatophores. Thus, this hypothesis predicts that thick spermatophore envelopes and signa evolve in polyandrous species, and that these adaptations are lost when monandry evolves subsequently. Here we test the expected associations between female mating pattern and presence/absence of signa, and review the scant information available on the thickness of spermatophore envelopes. METHODOLOGY/PRINCIPAL FINDINGS: We made a literature review and found information on female mating pattern (monandry/polyandry, presence/absence of signa and phylogenetic position for 37 taxa. We built a phylogenetic supertree for these taxa, mapped both traits on it, and tested for the predicted association by using Pagel's test for correlated evolution. We found that, as predicted by our hypothesis, monandry evolved eight times and in five of them signa were lost; preliminary evidence suggests that at least in two of the three exceptions males imposed monandry on females by means of specially thick spermatophore envelopes. Previously published data on six genera of Papilionidae is in agreement with the predicted associations between mating pattern and the characteristics of spermatophore envelopes and signa. CONCLUSIONS/SIGNIFICANCE: Our results support the hypothesis that signa are a product of sexually

    Full Text Available Hermaphroditism is a congenital anomaly characterized by the presentation of sexual characteristics of both sexes in one individual. Hermaphrodites can occur in every mammal species. Real and pseudo hermaphrodites can be distinguished. Both ovaries and testes (ovotestes are presented in real hermaphrodites, while the conformation of the individual does not correspond to any sex in particular. Pseudo hermaphrodites are more frequent. Male pseudo hermaphrodites have testes and female external genital characteristics, while female pseudo hermaphrodites have ovaries and rudimentary external genitals reassembling to masculine ones. Corrective surgical removal of a rudimental penis in a female pseudo hermaphrodite dog is presented in the paper.

  8. Sexual selection and senescence: male size-dimorphic ungulates evolved relatively smaller molars than females.

    As a general rule, males of sexually dimorphic ungulate species have evolved larger body size than females but shorter reproductive life spans as elements of their strategy for intrasexual competition for mating opportunities. Evolutionary theories of senescence predict that the durability of somatic structures should relate to the length of reproductive life span. This prediction has recently been tested for red deer (Cervus elaphus): molariform teeth of males are smaller and less durable than those of females, which corresponds with sex differences in reproductive life span. However, general evidence that male teeth are smaller than expected by allometric rules as a consequence of sexual selection for increasing male body mass requires an interspecific comparison between dimorphic and nondimorphic ungulates. Here we investigate the relationship between cheek-teeth size (occlusal surface area; OSA) and body mass in 123 species of extant ungulates. We found lower slopes for dimorphic species compared with nondimorphic ones and smaller OSA, relative to body mass, in males of dimorphic species compared with females of dimorphic species. Rates of evolution of OSA relative to rates of evolution of body mass were greater in females than in males and also greater in nondimorphic than in dimorphic species. Our results are consistent with the hypothesis that sexual selection in polygynous male ungulates favors body size more than tooth size, with possible consequences in male senescence via early depletion of male teeth compared to females.

    Polyandry (female multiple mating) has profound evolutionary and ecological implications. Despite considerable work devoted to understanding why females mate multiply, we currently lack convincing empirical evidence to explain the adaptive value of polyandry. Here, we provide a direct test of the controversial idea that bet-hedging functions as a risk-spreading strategy that yields multi-generational fitness benefits to polyandrous females. Unfortunately, testing this hypothesis is far from trivial, and the empirical comparison of the across-generations fitness payoffs of a polyandrous (bet hedger) versus a monandrous (non-bet hedger) strategy has never been accomplished because of numerous experimental constraints presented by most 'model' species. In this study, we take advantage of the extraordinary tractability and versatility of a marine broadcast spawning invertebrate to overcome these challenges. We are able to simulate multi-generational (geometric mean) fitness among individual females assigned simultaneously to a polyandrous and monandrous mating strategy. Our approaches, which separate and account for the effects of sexual selection and pure bet-hedging scenarios, reveal that bet-hedging, in addition to sexual selection, can enhance evolutionary fitness in multiply mated females. In addition to offering a tractable experimental approach for addressing bet-hedging theory, our study provides key insights into the evolutionary ecology of sexual interactions.

    We evaluated the efficacy and safety of three doses of a novel alprostadil cream in a randomized, double-blind, placebo-controlled study in 94 women presenting with female sexual arousal disorder of at least 6 month s duration. We sent the subjects home with 10 premeasured doses of 500 g, 1000 g, or 1500 g alprostadil or a placebo cream to be applied to the vulvar area prior to vaginal intercourse over a period of 6 weeks. The primary efficacy parameter, the arousal success rate (as measured by diary responses to the Female Sexual Encounter Profile [FSEP]), was highest in the alprostadil 1000 g group and lowest in the 500 g group, but the responses were not different from that of the placebo cream, at the p = 0.05 level, for any of the three alprostadil doses. However, the change from baseline for Item 6 of the Female Sexual Function Index (FSFI; Rosen et al., 2000; satisfaction with arousal during sexual activity) suggested an important dose-related trend (p = 0.173; 1500 g versus placebo). The mean percent responder rate (responder = > 50% arousal success rate with > 3 sexual attempts) suggested a dose-response effect (p = 0.157; 1500 g versus placebo). Adverse events were generally mild or moderate in intensity and mainly involved localized reactions in the genital area.

    Tracing a series of intertextually linked short stories from the 1990s to the present by women writers from Nigeria and its diaspora-Chimamanda Ngozi Adichie, Unoma Azuah, Chinelo Okparanta, and Lola Shoneyin-I suggest that although the figure of the African lesbian appears "new" in the context of heightened contemporary attention to the issue of homosexuality, this figure has a literary history. Ghanaian Ama Ata Aidoo's novel Our Sister Killjoy: Or, Reflections From A Black-Eyed Squint (1977) inaugurates this formation, in which the imagining of female same-sex desire is entangled with articulating the experience of migration under the shadow of imperial histories. In these short stories, the emphasis on the difficulties of love in puritanical times and transnational places produces the figure of the African lesbian as a symbol of appealingly human vulnerability, resilience, and complexity.

    The aim of the present study was to assess female sexual function in an obese group (250 women) and to compare it with a control group (100 women), among 25-35-year-old uncircumcised Egyptian women, using female sexual function index (FSFI) score. FSFI total score of ⩽ 26.55 was considered diagnostic of Female Sexual Dysfunction (FSD). The percentage of FSD in the obese group was 73.6% while it was 71% in the control group, which was statistically insignificant (P > 0.05). The difference between both groups regarding the total (FSFI) score was insignificant (P > 0.05), but arousal and satisfaction domains scores were significantly lower in the obese group. In the obese group, a strong negative correlation between body mass index and arousal, orgasm and the total FSFI score was found. Women with excessive obesity had the lowest total FSFI score. In the obese group, college graduates had the highest total scores and all domain scores of FSFI followed by high school graduates while the least educated women had the lowest scores and when these subgroups were compared, significant differences were found among them. We conclude that in uncircumcised 25-35-year-old Egyptian women, obesity is not a major detrimental factor for FSD, but it may affect some sexual domains such as arousal and satisfaction, although excessive obesity is associated with FSD. Also, educational and cultural factors may have an impact on perception of sex and pleasure.

    We investigated prevalence and correlates of sexual risk behaviours among male and female sex workers in Tijuana, Mexico, the busiest border crossing area on the US - Mexico border, analysing survey data from a purposive, cross-sectional sample of male and female sex workers who worked in a range of indoor and outdoor settings. Logistic regression was used to determine factors that were associated with sexual risk-taking, defined as failing to use a condom with last client. In bivariate regression models, gender, work setting (e.g., indoor vs. outdoor), poverty, engaging in survival sex, marital status and perceived drug addiction were correlated with sexual risk. When controlling for work location, housing insecurity, poverty, survival sex, marital status and perceived drug addiction, male sex workers were still 10 times more likely than female sex workers (FSW) to engage in sex without a condom during their last encounter with a client. And, although FSW were significantly more likely than males to have used a condom with a client, they were significantly less likely than males to have used a condom with their regular partner. Future research should further examine how gender shapes sexual risk activities in both commercial and non-commercial relationships.

    Full Text Available OBJECTIVE: To estimate the prevalence of female sexual dysfunction symptoms and the associated risk factors in a sample of patients with substance-related disorders admitted to a specialized in-patient care unit. METHODS: This study used a cross-section design, with eight months of data collection, conducted with substance-dependent women using structured questionnaires to collect socio-demographic data and identify their drug of choice. The Drug Abuse Screening Test, Short Alcohol Dependence Data questionnaire, Fagerstrom Test for Nicotine Dependence, and Arizona Sexual Experience Scale were also administered. RESULTS: The sample consisted of 105 women who had a mean age of 34.8 years (SD = 12.1, range = 18-65 and were predominantly heterosexual (74.3%, single (47.6%, Caucasian (50.5%, catholic (36.2%, and educated only to the level of primary education (40%, with a monthly family income of up to one minimum salary (37.5%. In 42.9% of the patients, crack was the drug of choice; 47.6% of the sample qualified for the Drug Abuse Screening Test (substantial problems related to drugs, 43.8% exhibited Short Alcohol Dependence Data (moderate or severe dependency, 47.6% exhibited Fagerstrom Test for Nicotine Dependence (high or very high nicotine dependence. The prevalence of sexual dysfunction symptoms was 34.2% (95% CI = [25.3, 44.1], and a high level of nicotine dependence and low income increased the chances of having sexual dysfunction by 2.72-fold and 2.54 fold, respectively. An association was also observed between female sexual dysfunction symptoms and schooling and levels of drug dependence. CONCLUSIONS: Female sexual dysfunction symptoms were common among this sample and primarily associated with high levels of nicotine use.

  16. Dressed for sex: red as a female sexual signal in humans.

    Andrew J Elliot

    Full Text Available BACKGROUND: In many non-human primate species, a display of red by a female serves as a sexual signal to attract male conspecifics. Red is associated with sex and romance in humans, and women convey their sexual interest to men through a variety of verbal, postural, and behavioral means. In the present research, we investigate whether female red ornamentation in non-human primates has a human analog, whereby women use a behavioral display of red to signal their sexual interest to men. METHODOLOGY/PRINCIPAL FINDINGS: Three studies tested the hypothesis that women use red clothing to communicate sexual interest to men in profile pictures on dating websites. In Study 1, women who imagined being interested in casual sex were more likely to display red (but not other colors on their anticipated web profile picture. In Study 2, women who indicated interest in casual sex were more likely to prominently display red (but not other colors on their actual web profile picture. In Study 3, women on a website dedicated to facilitating casual sexual relationships were more likely to prominently exhibit red (but not other colors than women on a website dedicated to facilitating marital relationships. CONCLUSIONS/SIGNIFICANCE: These results establish a provocative parallel between women and non-human female primates in red signal coloration in the mating game. This research shows, for the first time, a functional use of color in women's sexual self-presentation, and highlights the need to extend research on color beyond physics, physiology, and preference to psychological functioning.

    Incontinence and pelvic organ prolapse (POP) have an impact on sexuality. Few studies evaluate the impact of hysterectomy on sexual function. We designed the present observational prospective longitudinal cohort study in order to evaluate the impact of uterus preservation after POP repair on sexual function. Between January 2006 and January 2011, 107 patients with POP, mean age 58 ± 8.9 years, underwent colposacropexy with or without hysterectomy. All the women without uterine disease were offered the chance to preserve the uterus. All patients gave written informed consent and completed the Female Sexual Function Index (FSFI) questionnaire, before and after surgery, provided detailed case history, underwent urogynaecological examination and urodynamic assessment and completed the Urogenital Distress Inventory short form (UDI-6) and Incontinence Impact on Quality of Life short form (IIQ-7) questionnaires, and the satisfaction Visual Analogue Scale (VAS). One year after surgery patients repeated the FSFI questionnaire and underwent a clinical check-up. The primary end-point was post-operative sexual function as evaluated by the FSFI, the secondary end-points were objective anatomical and subjective success, defined respectively as no prolapse and no incontinence-related symptoms. Sixty-eight patients were included: 32 underwent uterus-sparing surgery and 36 hysterectomy plus colposacropexy. After surgery both groups had significant improvements in the total FSFI score and in the domains of desire, arousal and orgasm. The median post-operative scores of desire, arousal, and orgasm domains showed significant improvements in the uterus-sparing group compared with the hysterectomy group. None of the women had a uterine or vault prolapse recurrence. Our data demonstrate that POP plays a role in female sexual dysfunction and uterus sparing surgery is associated with a greater improvement in sexual function.

    Despite their large numbers, and important role in the HIV epidemic in India, male clients of female sex workers (FSWs) are a difficult to reach population and little is known about their sexual behaviors. Using data from an integrated behavioral and biological assessment of 684 clients in Bangalore in 2012, we examined factors associated with their reports of having sex with three or more different female sex workers in the last month, and anal sex with sex workers. We included sociodemographic and sexual behavior factors and, for the first time in client studies in India, included data on the use of pornography and sexual enhancement products (SEPs) such as pills, oils, and sprays, in our multivariable analyses of client risk. Seventy-eight percent of clients had seen pornographic material and 8% reported ever having used SEPs. The profiles of men practicing the two risk behaviors examined were quite different. Travel in the past year, drunkenness in the past month, young age at first commercial sex, non-use of condoms at last sex, and finding sex workers in public places (but not use of pornography and SEPs) were independently associated with multiple partnering. Sex with a man or transsexual, being a white collar worker, seeking out FSWs at home, pornography and SEP use, and condom use at last FSW sex, were all independently associated with anal sex with an FSW. More research is needed to better understand the links between pornography and SEPs, and HIV risk behaviors, and HIV prevention programs need to be cognizant of the importance of ensuring that condom use is adequately promoted and supported in the context of anal sex in female sex worker-client interactions.

    Full Text Available Abstract Background Female sexual dysfunctions (FSD are prevalent multifactor problems that in general remain misdiagnosed in primary health care. This population-based study investigated help-seeking behaviors among women with FSD in Iran. Methods This was a cross sectional study carried out in Kohgilouyeh-Boyer-Ahmad province in Iran. Using quota sampling all sexually active women aged 15 and over registered in primary health care delivery centers were studied. Experience of sexual problems was assessed using an ad-hoc questionnaire (Female sexual dysfunction: help-seeking behaviors survey containing 14 items. Trained female nurses interviewed all participants after a verbal informed consent. Data were analyzed in a descriptive manner. Results In all 1540 women were studied. Of these, 786 (51% cases had experienced at least one of the FSD problems. Results showed that 35.8% of women with FSD had sought no professional help and the most reasons for not seeking help were identified as: 'time constraints' and believing that it 'did not occur to me' (39.1 and 28.5% respectively. Sixty one percent of women who sought help for FSD reported that 'doctor gave me a definite diagnosis' and 'a definite treatment plan was given' in 57% of cases. Conclusion The study findings indicated that FSD problems were prevalent and many women did not seek help for their problem. Finding 'time constraints' and believing that the problem 'did not occur to me' as the most cited reasons for not seeking help might facilitate to understand potential barriers that exist in recognition and treatment of the female sexual dysfunctions. Since FSD might have a negative impact on interpersonal relationships and women's quality of life, it seems that there is need to address the problem both at local and national primary health care services.

    The Korea Institute for Population and Health (KIPH) conducted a survey from January 1, 1983, to June 30, 1984, to identify the sociopsychological and demographic characteristics of unmarried female factory workers and to develop a strategy for planning and implementing organized sex and family planning education and service programs for unmarried female workers in the factory setting. The respondents were 918 female factory workers in the industrial areas of Guro, Gumi, and Masan. Their average age was 21 years with a 3.4 year work career. Respondents' knowledge level of sex, pregnancy, and contraceptive methods was low. The female factory workers preferred counselors outside rather than inside the work place. Although there was no question about the need for counseling for sexual problems among the female factory workers, their user rate was low.

    The peripheral sexual response is achieved by the the Clitoro-Urethro-Vaginal Complex who is responsible of the transmission of the sensitive stimulation to the CNS where this information is modulated by the different cerebral areas. These latter will send this message to the peripheral sexual organs using efferent somatic and autonomic pathways able to induce vaso congestive response of clitoridal area with contractions of pelvic floor muscles. Muscles stretch injuries after obstetrical or surgical trauma can decrease the quality of the sexual peripheral response. These modifications of peripheral sexual response have to be evaluated with a specific questionnaire and pelvic floor clinical examination and recently, with a new microsystem device able to record continuously intra-vaginal pressure modifications.

    Preclinical and clinical research investigating female sexual motivation has lagged behind research on male sexual function. The present review summarizes recent advances in our understanding of the specific roles of various brain areas, as well as our understanding of the role of dopaminergic neurotransmission in sexual motivation of the female rat. A number of behavioral paradigms that can be used to thoroughly evaluate sexual behavior in the female rat are first discussed. Although traditional assessment of the reflexive, lordosis posture has been useful in understanding the neuroanatomical and neurochemical systems that contribute to copulatory behavior, the additional behavioral paradigms described in this review have helped us expand our understanding of appetitive and consumatory behavioral patterns that better assess sexual motivation - the equivalent of "desire" in humans. A summary of numerous lesion studies indicates that different areas of the brain, including forebrain and midbrain structures, work together to produce the complex repertoire of female sexual behavior. In addition, by investigating the effects of commonly addictive drugs, we are beginning to elucidate the role of dopaminergic neurotransmission in female sexual motivation. Consequently, research in this area may contribute to meaningful advances in the treatment of human female sexual dysfunction.

    Male rats that copulate to ejaculation with female rats bearing an odor show a learned preference to ejaculate selectively with females that bear the odor. This conditioned ejaculatory preference reflects an association between the odor and the reward state induced by ejaculation. Although little is known about the neuronal mechanisms that mediate this form of learning, convergence of genitosensory and olfactory inputs occurs in both hypothalamic and cortical regions, notably within primary olfactory (piriform) cortex, which may be involved in the encoding or storage of the association. The present study contrasted the ability of genital investigations, mounts, intromissions, ejaculations, and a sexually conditioned olfactory stimulus, to enhance evoked synaptic field potentials in the piriform cortex. Rats in the Paired group underwent conditioning trials in which they copulated with sexually receptive females bearing an almond odor. Rats in the Unpaired control group copulated with receptive females bearing no odor. Responses in the piriform cortex evoked by electrical stimulation of the olfactory bulb were recorded in male rats as they engaged in different aspects of sexual behavior, and were also recorded after conditioning, during exposure to cotton swabs bearing the almond odor. The monosynaptic component of responses was increased during intromission and ejaculation, and the late component of responses was increased during anogenital sniffing and mounting (with or without intromission). However, no differences in the amplitudes of evoked responses were found between the Paired and Unpaired groups, and no differences in synaptic responses were found during presentation of the odor after conditioning. These data indicate that short-term alterations in synaptic responsiveness occur in piriform cortex as a function of sexual stimulation in the male rat, but that responses are not significantly altered by a conditioned odor.

    Full Text Available Variations in parental care predict the age of puberty, sexual activity in adolescence and the age at first pregnancy in humans. These findings parallel descriptions of maternal effects on phenotypic variation in reproductive function in other species. Despite the prevalence of such reports, little is known about potential biological mechanisms and this especially true for effects on female reproductive development. We examined the hypothesis that parental care might alter hypothalamic-pituitary-ovarian function and thus reproductive function in the female offspring of rat mothers that vary pup licking/grooming (LG over the first week postpartum. As adults, the female offspring of Low LG mothers showed 1 increased sexual receptivity; 2 increased plasma levels of luteinizing hormone (LH and progesterone at proestrus; 3 an increased positive-feedback effect of estradiol on both plasma LH levels and gonadotropin releasing-hormone (GnRH expression in the medial preoptic region; and 4 increased estrogen receptor alpha (ERalpha expression in the anterioventral paraventricular nucleus, a system that regulates GnRH. The results of a cross-fostering study provide evidence for a direct effect of postnatal maternal care as well as a possible prenatal influence. Indeed, we found evidence for increased fetal testosterone levels at embryonic day 20 in the female fetuses of High compared to Low LG mothers. Finally, the female offspring of Low LG mothers showed accelerated puberty compared to those of High LG mothers. These data suggest maternal effects in the rat on the development of neuroendocrine systems that regulate female sexual behaviour. Together with studies revealing a maternal effect on the maternal behavior of the female offspring, these findings suggest that maternal care can program alternative reproductive phenotypes in the rat through regionally-specific effects on ERalpha expression.

    Issue addressed: Unwanted sexual attention and unhealthy intimate relationships have the potential to have serious negative health consequences. To date, there has been scant focus on these issues among university students in Australia. The aim of the current study was to describe the extent of unwanted sexual attention and unhealthy intimate relationships experienced in their lifetime by female university students aged 18-25 years.Methods: A cross-sectional study was undertaken involving 465 female students aged 18-25 years. Students were recruited through one faculty within a Victorian university and invited to complete an anonymous online questionnaire.Results: Sixty-seven per cent (n = 312) of female students reported experiencing unwanted sexual attention in their lifetime. The most common form of unwanted sexual attention was kissing or touching over clothes (98%; n = 306). Over 43% (n = 124) of the female students reported that the experience of unwanted sexual experience occurred after their protests were ignored. Thirty per cent (n = 135) of the female students reported experiencing at least one element of an unhealthy intimate relationship.Conclusions: The high rates of unwanted sexual attention and unhealthy intimate relationships among female university students is of concern given the negative impact such events can have on individual's physical, emotional and social well being.So what?: Public health and health promotion action is required to prevent female students from experiencing unwanted sexual attention and unhealthy intimate relationships, and to address the negative health and well being consequences.

  7. Only half right: species with female-biased sexual size dimorphism consistently break Rensch's rule.

    Thomas J Webb

    Full Text Available BACKGROUND: Most animal species display Sexual Size Dimorphism (SSD: males and females consistently attain different sizes, most frequently with females being larger than males. However the selective mechanisms driving patterns of SSD remain controversial. 'Rensch's rule' proposes a general scaling phenomenon for all taxa, whereby SSD increases with average body size when males are larger than females, and decreases with body size when females are larger than males. Rensch's rule appears to be general in the former case, but there is little evidence for the rule when females are larger then males. METHODOLOGY/PRINCIPAL FINDINGS: Using comprehensive data for 1291 species of birds across 30 families, we find strong support for Rensch's rule in families where males are typically larger than females, but no overall support for the rule in families with female-biased SSD. Reviewing previous studies of a broad range of taxa (arthropods, reptiles, fish and birds showing predominantly female-biased SSD, we conclude that Rensch's conjecture is the exception rather than the rule in such species. CONCLUSIONS/SIGNIFICANCE: The absence of consistent scaling of SSD in taxa with female-biased SSD, the most prevalent direction of dimorphism, calls into question previous general evolutionary explanations for Rensch's rule. We propose that, unlike several other ecological scaling relationships, Rensch's rule does not exist as an independent scaling phenomenon.

    Sexual size dimorphism (SSD) has long attracted the attention of biologists,and life-history variation is thought to play an important role in the evolution of SSD.Here we quantified SSD and female reproductive traits to identify potential associations between SSD and female reproduction in the white-striped grass lizard Takydromus wolteri.In a population from Chuzhou,China,the largest male and female were 53.0 mm and 57.5 mm in snout-vent length (SVL),respectively.Females were larger in SVL and abdomen length,whereas males were larger in head size and tail length.Females produced up to five clutches of eggs during the breeding season,with large females producing more clutches and more eggs per clutch than small ones.As a result,large females had a higher annual fecundity and reproductive output.Egg size was positively correlated with maternal SVL in the first clutch,but not in subsequent clutches.These results suggest that T.wolteri is a species with female-biased SSD,and that fecundity selection,in which large females have higher fecundity due to their higher capacity for laying eggs,is likely correlated with the evolution of SSD in this species [Current Zoology 58 (2):236-243,2012].

    Full Text Available Gulsen Unlu, Burcu Cakaloz Department of Child and Adolescent Psychiatry, Faculty of Medicine, Pamukkale University, Denizli, Turkey Purpose: Child sexual abuse and sexual dating violence victimization are common problems that are known to have long-term negative consequences. This study aimed to compare the sociodemographic, abuse-related, and clinical features of female adolescents who were sexually abused by different perpetrators, and identify the factors associated with suicidality and nonsuicidal self-injury (NSSI in these cases. Patients and methods: Data of 254 sexually abused female adolescents between the ages of 12–18 years were evaluated. The cases were classified into three groups, namely “sexual dating violence”, “incest”, and “other child sexual abuse”, according to the identity of the perpetrator. The three groups were compared in terms of sociodemographic, abuse-related, and clinical features. Results: Major depressive disorder was the most common psychiatric diagnosis, which was present in 44.9% of the cases. Among all victims, 25.6% had attempted suicide, 52.0% had suicidal ideation, and 23.6% had NSSI during the postabuse period. A logistic regression analysis revealed that attempted suicide was predicted by dating violence victimization (adjusted odds ratio [AOR] =3.053; 95% confidence interval [CI] =1.473, 6.330 and depression (AOR =2.238; 95% CI =1.226, 4.086. Dating violence victimization was also the strongest predictor of subsequent suicidal ideation (AOR =3.500; 95% CI =1.817, 6.741. In addition, revictimization was determined to be an important risk factor for both suicidal ideation (AOR =2.897; 95% CI =1.276, 6.574 and NSSI (AOR =3.847; 95% CI =1.899, 7.794. Conclusion: Perpetrator identity and revictimization are associated with negative mental health outcomes in sexually victimized female adolescents. Increased risk of suicidality and NSSI should be borne in mind while assessing cases with dating

    Full Text Available The objective was to describe the sexual life satisfaction of couples in the climacteric stage and determine whether there are differences between the perception of satisfaction and the sex life of each partner. We studied 142 couples obtained by stratified sampling of family health centers, Concepción, Chile. 66% of women and 84% of men reported being very or somewhat satisfied with their sex lives. Slight concordance was found between the responses of the partners in relation to satisfaction with their sexual life. Moreover, a slight degree of agreement was found between the sexual life satisfaction reported by women and their partners' perceptions of the women's sexual life satisfaction. Additionally, a slight degree of agreement was reported between the sexual life satisfaction reported by men and their partners' perceptions of the men's sexual life satisfaction. This study provides new information about Chilean couples in the climacteric stage in relation to self-reported sexual satisfaction and perceived satisfaction in couples.

    Full Text Available Introduction: The research was conducted among patients of the Department of Perinatology and Gynaecology of the Poznań University of Medical Sciences. Its aim was to investigate the influence of overweight and obesity on female sexuality during the perimenopausal period. Preliminary results of the research are presented in the thesis, which was as a matter of fact intended as a preliminary report. The examination of sexual functions of the patients was performed with the use of the Female Sexual Function Index (FSFI form. Material and methods: Sixty-one women during the perimenopausal period filled out the survey, with the average age of these women being 51 years. Forty-two of the examined women had an appropriate body mass index (BMI, i.e. between 18.5 and 25, while for 19 of the women, the BMI was above normal. For statistical analysis and in order to assess the differences between the two above-mentioned groups of patients, the nonparametric Mann-Whitney test was applied. A statistically significant value was assumed at p < 0.05. The results of the conducted research indicated no such difference between the women with differing BMI for the specific domains of the FSFI test. Results: The results obtained show that research in the area needs to be continued. Conclusions: All the hitherto existing scientific studies also seem to indicate that the influence of overweight and obesity on female sexuality during the perimenopause has not yet been unambiguously proven. Beyond any doubt, however, sexual disorders appear in women at this time of life and the factors which determine them can vary greatly. Given the character of the situation, women ought to be supported both by a team of specialists representing different branches of medicine as well as by their relatives. The whole situation also calls for more research of the important subject matter.

    The recent NCCN Guidelines for Survivorship recommend systematic evaluation and multidisciplinary treatment of cancer-related sexual dysfunctions. However, most oncology professionals fail to routinely assess sexual problems and lack expertise to treat them. An Internet-based intervention was designed to educate female patients and their partners about cancer-related sexual problems, describe medical treatment options and how to find expert care, and provide self-help strategies. A randomized trial assessed efficacy of the intervention when used as self-help versus the same Web access and 3 supplemental counseling sessions. Survivors of localized breast or gynecologic cancers completed online questionnaires at baseline, posttreatment, and 3- and 6-month follow-up, including the Female Sexual Function Index (FSFI), the Menopausal Sexual Interest Questionnaire (MSIQ), the Brief Symptom Inventory-18 (BSI-18) to assess emotional distress, and the Quality of Life in Adult Cancer Survivors (QLACS) scale. Program evaluation ratings were completed posttreatment. Fifty-eight women completed baseline questionnaires (mean age, 53 ± 9 years). Drop-out rates were 22% during treatment and 34% at 6-month follow-up. Linear mixed models for each outcome across time showed improvement in total scores on the FSFI, MSIQ, and QLACS (P<.001) and BSI-18 (P=.001). The counseled group improved significantly more on sexuality measures, but changes in emotional distress and quality of life did not differ between groups. Program content and ease of use were rated positively. Research is needed on how best to integrate this intervention into routine clinical practice, and particularly how to improve uptake and adherence.

    It has been generally assumed that partner's erectile dysfunction, premature, and delayed ejaculation play a significant role in determining female sexual dysfunction (FSD). This study aimed to evaluate the role of the male partner's sexual function, as perceived by women, in determining FSD. A consecutive series of 156 heterosexual women consulting our clinic for FSD was retrospectively studied. All patients underwent a structured interview and completed the Female Sexual Function Index (FSFI). FSFI total score decreased as a function of partner's age, conflicts within the couple, relationship without cohabitation and the habit of engaging in intercourse to please the partner; FSFI total score increased as a function of frequency of intercourse, attempts to conceive and fertility-focused intercourse. FSFI total score showed a negative, stepwise correlation with partner's perceived hypoactive sexual desire (HSD) (r = -0.327; p premature and delayed ejaculation. In an age-adjusted model, partner's HSD was negatively related to FSFI total score (Wald = 9.196, p = 0.002), arousal (Wald = 7.893, p = 0.005), lubrication (Wald = 5.042, p = 0.025), orgasm (Wald = 9.293, p = 0.002), satisfaction (Wald = 12.764, p premature, and delayed ejaculation of the partner may not act as a primary contributing factor to FSD, as determined by FSFI scores; conversely, women's sexuality seems to be mostly impaired by the perceived reduction in their partner's sexual interest.

  14. Development and validation of the response to sexual difficulties scale.

    Leading models of sexual dysfunction, such as those proposed by Masters and Johnson (1970), Barlow (1986), and Janssen, Everaerd, Spiering, and Janssen (2000), emphasize the role of anxiety and self-monitoring in the development and persistence of sexual difficulties. These models have considerable explanatory power, but focus on the intrapersonal factors that yield anxiety and self-monitoring. Accounting for the interpersonal context in which sexual activity occurs is also likely to be important. For example, anxiety and self-monitoring may arise from negative, yet accurate, predictions about how one's partner will respond to one's own sexual functioning difficulties. The current studies describe the development and validation of the Response to Sexual Difficulties Scale (RSDS), which was designed to assess how one expects one's partner to respond to one's own sexual difficulties (RSDS-Own Difficulties) and how one expects oneself to respond to one's partner's sexual difficulties (RSDS-Partner Difficulties). Study 1 established the initial reliability and construct validity of the RSDS-Own Difficulties in a sample of adults in committed relationships (N = 59). Study 2 further examined the construct and discriminant validity of the RSDS Own Difficulties and Partner Difficulties in a sample of heterosexual couples (N = 87). Results indicated that both measures had strong internal consistency and were not redundant with measures of mood or personality. Scores on the RSDS-Own Difficulties and Partner Difficulties were strongly associated, indicating that reports of one's own response to one's partner's difficulty matched the partner's assessment of the reaction. RSDS scores predicted sexual functioning, relationship satisfaction, sexual satisfaction, and sexual communication. The RSDS may, then, provide a useful means of assessing the role of interpersonal factors in the development and persistence of sexual difficulties.

    A cross-sectional study was conducted among youth clients of hotel-based female sex workers (YCHBFSWs) in nine randomly selected hotels in Bangladesh to examine sexual-risk behaviour, condom use and determinants of condom use in last sex, knowledge of HIV, sexually transmitted infection (STI) prevalence and STI care-seeking behaviour. A prestructured questionnaire was used to collect sociodemographic, behavioural, clinical information; urine specimens (before sex) and blood were collected for diagnosis of Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, syphilis and herpes simplex virus 2 (HSV2) infection. One thousand and thirteen participants were enroled in the study. Approximately half of them reported visiting female sex workers (FSWs) at least once a month and 25% visited FSWs at least once a week. Only 12% of participants reported regular condom use. The prevalence of N. gonorrhoeae, C. trachomatis, T. vaginalis, syphilis and HSV2 was 2.2%, 3.9%, 7.2%, 2.6% and 12.9%, respectively. Only 15.3% of the YCHBFSW sought STI care in the past year. Negotiation of condom use with FSWs was the main determinant (odds ratio = 17.95) for condom use at last sex. Male clients of FSWs, including YCHBFSW, are an important bridge population for HIV transmission in Bangladesh and HIV interventions should be designed and implemented for them.

    This content analysis examines written documentation of telephone calls to a regional sexual assault hotline over a 5-year period. All male callers identified as primary victims were selected for analysis (n = 58) and a corresponding sample of female primary victims (n = 58) were randomly selected for comparison to better understand the help-seeking behavior of sexual assault survivors and inform services accordingly. A summative content analysis revealed significant contrasting themes between male and female victims, including females significantly receiving more referrals and males accessing the hotline to tell their experience of being sexually assaulted due to perceived limited support. Implications for training, practice, and future research are discussed.

    Sexually transmitted infections constitute economic burden for developing countries, exposure to causative agents is an occupational hazard for female sex workers. Targeted interventions for this population can reduce the incidence and prevalence of sexually transmitted infections including human immunodeficiency virus, but barriers exists which can hinder effective implementation of such programs. This descriptive cross sectional study sought to assess the prevalence, knowledge and treatment practices of sexually transmitted infections among brothel based female sex workers. Three hundred and twenty three consenting female sex workers were surveyed using pre tested, interviewer administered questionnaires. More than half of the respondents (54.2%) had poor knowledge of symptoms of sexually transmitted infections. Only 13.9% were aware that sexually transmitted infections could be asymptomatic. The self reported prevalence of symptomatic sexually transmitted infections was 36.5%. About half of those with sexually transmitted infectionss sought treatment in a hospital or health centre while 32.5% from a patent medicine vendor. Most respondents (53.8%) mentioned the perceived quality of care as the main reason for seeking treatment in their chosen place. More of the respondents with good knowledge of sexually transmitted infections reported symptoms compared to those with fair and poor knowledge. The knowledge of sexually transmitted infections among these female sex workers is poor and the prevalence is relatively high. Efforts to improve knowledge promote and encourage preventive as well as effective treatment practices must be made for this population.

    Female sexual desire and arousal problems have been shown to have a heritable component of moderate size. Previous molecular genetic studies on sexual desire have mainly focused on genes associated with neurotransmitters such as dopamine and serotonin. Nevertheless, there is reason to believe that hormones with more specific functions concerning sexuality could have an impact on sexual desire and arousal. The aim of the present study was to investigate the possible effects of 17 single nucleotide polymorphisms (SNPs) located in estrogen receptor genes on female sexual desire and subjective and genital arousal (lubrication). Based on previous research, we hypothesized that ESR1 and ESR2 are relevant genes that contribute to female sexual desire and arousal. The desire, arousal, and lubrication subdomains of the Female Sexual Function Index self-report questionnaire were used. The present study involved 2,448 female twins and their sisters aged 18-49 who had submitted saliva samples for genotyping. The participants were a subset from a large-scale, population-based sample. We found nominally significant main effects on sexual desire for three ESR2 -linked SNPs when controlled for anxiety, suggesting that individuals homozygous for the G allele of the rs1271572 SNP, and the A allele of the rs4986938 and rs928554 SNPs had lower levels of sexual desire. The rs4986938 SNP also had a nominally significant effect on lubrication. No effects for any of the SNPs on subjective arousal could be detected. The number of nominally significant results for SNPs in the ESR2 gene before correcting for multiple testing suggests that further studies on the possible influence of this gene on interindividual variation in female sexual functioning are warranted. In contrast, no support for an involvement of ESR1 was obtained. Our results should be interpreted with caution until replicated in independent, large samples. © 2014 International Society for Sexual Medicine.

    The descriptive cross-sectional study of 2,235 Korean postpartum women was conducted to explore (a) feeding types with related factors, (b) the perceived benefits of each feeding type, (c) the perceived sexuality-related barriers to breast-feeding, and (d) the perceived relative significance of breast functions. The most frequently utilized feeding type was breast-feeding only. The gender of infants, vaginal delivery, not being employed, having a nuclear family, previous breast-feeding experience, and previously receiving breast-feeding education were statistically significant factors of breast-feeding. Breast-feeding and mixed feeding mothers indicated that their feeding choices were based on nutritional benefits, convenience, and improving family relationships. Only breast-feeding mothers reported changes in breast shape as a perceived sexuality-related barrier to breast-feeding. All mothers reported that infant feeding was a more significant concern than female sexual functioning, but post hoc Schéffe revealed that the breast-feeding mothers appreciated infant feeding function more than female sexual functioning.

    Full Text Available Introduction: The need of love plays an important role in the lives of adolescents. The success they integrate their sexuality with, depends on a complex set of factors. Objective: To characterize sexual and reproductive behaviour of female high school students. Methods: A descriptive study of a sample comprising 180 female students from the 9th grade in the urban area of Cumanayagua, from September 2007 to June 2008. Variables that were analyzed: whether they kept relationships involving sex at the time of the study, age at onset of the relationships and primary motivations for its initiation, contraceptives use and most commonly used contraceptives and reproductive and obstetric history (abortions, menstrual regulation and delivery . Results: 56.1% kept relationships involving sex at the time of the study. The average age of onset of these relationships was between 13 (37.6% and 14 (43.6% years old. The main motivation was physical attraction in all age groups with 29.7%. A considerable group experienced unprotected sexual intercourse (57.4%, representing more than half of the total and only 42.6% protect themselves, mainly using condoms. Menstrual regulations were performed in 55.5% of the students as well as pregnancy interruptions through the uterine cavity curettage method in 22.2% of them. 5.6% had had an abortion. Conclusions: The studied adolescents are developing inappropriate sexual conducts.

    The present study examined the associations between initiation and intensity of substance use and with sexual experience with and without a history of teenage pregnancy. Participants were high school females (weighted n = 3,451) who participated in the 1999-2003 Youth Risk Behavior Surveillance System, a cross-sectional, nationally representative survey. Multinomial multivariable logistic regression was used to assess the likelihood of being sexually experienced (but never pregnant) and teenage pregnancy (reference group: never had sexual intercourse) as a function of age at substance use initiation (i.e., age 12 or younger, 13-14 years of age, and age 15 or older) and intensity of substance use (i.e., nonuser, experimental/ new or nondaily, nonexperimental/daily user) for alcohol, cigarettes, and marijuana, while controlling for race/ethnicity, metropolitan location, symptoms of depression, and illegal drug availability at school. A major finding of our study is that substance use behaviors across each substance (alcohol, cigarettes, and marijuana) independently contributed to an increased risk in sexual intercourse experience with and without a history of teenage pregnancy (vs. nonsexually experienced females). A dose-response relationship was also observed between an increased likelihood of a teenage pregnancy and marijuana behaviors. Furthermore, the risk for teenage pregnancy was compounded for daily cigarette smokers who initiated use at age 12 or younger. Screening substance use behaviors can help to identify girls who may benefit from pregnancy prevention strategies. Targeting cigarette and marijuana behaviors as early as age 12 or younger may provide an added benefit. Prevention strategies should also consider the role of race above and beyond substance use behaviors.

    The role of women in the sex trafficking of minors in the United States has received limited research attention. Case study analysis of 49 female pimps from federal, state, and local cases were analyzed to explore whether there were differences in the penalties given to females when compared with their male co-defendants, and cross-case analysis was conducted to identify themes that represent female pimp typologies. Both prison sentence and probation sentences were significantly lower for female co-defendants when compared with their male co-defendants. Five discrete typologies were developed including Bottom, Madam/Business Partner, Family, Girilla, and Handler. Each of these had unique features regarding violence toward their minor victims, co-defendants, actions during the sexual exploitation of the minor, and sentencing outcomes. Implications for practice and future research were recommended. © The Author(s) 2014.

    To evaluate the female sexual dysfunction in both type 1 and type 2 diabetes mellitus (DM). This cross-sectional study was carried out at Suez Canal University Hospitals from the start of February 2015 to the end of May 2016 among 189 married premenopausal women attending endocrinology and diabetology outpatient clinic for regular follow-up; 25 of whom refused to participate and 18 more were excluded due to incomplete data sets resulting in a final sample of 146 diabetic females. Ninety healthy women were recruited from the administrative staff at the hospital as a control group. Sexual dysfunction was assessed using female sexual function index (FSFI), a validated 19-item, self-administered, screening questionnaire comprising the six major sexual domains: desire, arousal, lubrication, orgasm, satisfaction and pain. Responses to each question were reported and scored on 0-5 scale with 0 representing no sexual activity and 5 suggestive of normal sexual activity. Prevalence of sexual dysfunction was significantly higher in both type 1 and 2 DM groups (44 and 25%, respectively) than in the control group (9%). FSFI mean total score was significantly lower in type 1 DM (21.1 ± 3.9) than type 2 DM (26.4 ± 4.2) and both were significantly lower than the control group (31.5 ± 5.8). With regard to FSFI domains, mean values for desire, arousal, lubrication, orgasm, satisfaction and pain were significantly lower in both type 1 and type 2 DM groups when compared with the controls. FSD is a significant health problem among premenopausal diabetic Egyptian women. Type 1 DM women were more affected than type 2 DM that in turn was more affected than healthy control females.

    The Jamaican government has provided targeted HIV and sexually transmitted infection prevention, treatment, and other services for female sex workers (FSW) since 1989. HIV prevalence among FSW declined from 20 to 12% between 1989 and 1994, then to 9% in 2005, 5% in 2008, and 4.1% in 2011. This article distills the literature and two decades of experience working with FSW in Jamaica. Drawing on the constant comparative method, we put forward an innovative conceptual framework for explaining sexual decision-making and risk behaviors within both transactional and relational sexual situations. This framework helps fill the gaps in existing models that focus on individual behaviors. The model identifies interactions between environmental and structural elements of sex work, and three individual-level factors: risk perception, perceived relationship intimacy, and perceived control, as the four primary mediating factors influencing sexual decision-making among FSW. We propose that other factors such as violence, socioeconomic vulnerability, and policy/legal frameworks influence sexual decision-making through these primary mediating factors. This conceptual model may offer a useful framework for planning and evaluating prevention interventions among sex workers. However, it remains to be tested in order to establish its value.

    Little prospective data exists regarding the procedures constituting female genital plastic/cosmetic surgery (FGPS). To evaluate whether the procedures of labiaplasty and vaginoperineoplasty improve genital self image, and evaluate effects on sexual satisfaction. Prospective cohort case-controlled study of 120 subjects evaluated at baseline, 6, 12, and 24 months postoperative, paired with a demographically similar control group. Interventions include labiaplasty, clitoral hood reduction, and/or aesthetic vaginal tightening, defined as perineoplasty + "vaginoplasty" (aka "vaginal rejuvenation."). Outcome measures include body image, genital self-image, sexual satisfaction, and body esteem. As a group, study patients tested at baseline showing body dissatisfaction, negative genital self-image, and poorer indices of sexual satisfaction. Preoperative body image of study patients were in a range considered to be mild to moderately dysmorphic, but matched controls at one and two years; genital self-image scores at entry were considerably lower than controls, but by 2-year follow-up had surpassed control value at entry. Similarly, sexual satisfaction values, significantly lower at entry, equaled at one, and surpassed control values, at 2 years. Postoperatively, at all points in time, these differences in body image and genital self-image disappeared, and sexual satisfaction markedly improved. Overall body esteem did not differ between study and control groups, with the exception of the genital esteem quotient, which improved after surgery. Women requesting and completing FGPS, when tested by validated instruments, at entry report sexual dissatisfaction and negative genital self-image. When tested at several points in time after surgery up to two years, these findings were no longer present. When performed by an experienced surgeon, FGPS appears to provide sexual and genital self-image improvement. 2 Therapeutic. © 2016 The American Society for Aesthetic Plastic Surgery

    Background Genital secretions collected from adult women exhibit in vitro activity against herpes simplex virus (HSV) and Escherichia coli (E. coli), but prior studies have not investigated this endogenous antimicrobial activity or its mediators in adolescent females. Methodology/Principal Findings Anti-HSV and anti-E.coli activity were quantified from cervicovaginal lavage (CVL) specimens collected from 20 sexually active adolescent females (15–18 years). Soluble immune mediators that may influence this activity were measured in CVL, and concentrations of Lactobacillus jensenii and crispatus were quantified by PCR from vaginal swabs. Results for adolescents were compared to those obtained from 54 healthy, premenopausal adult women. Relative to specimens collected from adults, CVL collected from adolescent subjects had significantly reduced activity against E. coli and diminished concentrations of protein, IgG, and IgA but significantly increased anti-HSV activity and concentrations of interleukin (IL)-1α, IL-6 and IL-1 receptor antagonist. Vaginal swabs collected from adolescent subjects had comparable concentrations of L. crispatus but significantly reduced concentrations of L. jensenii, relative to adult swabs. Conclusions/Significance Biomarkers of genital mucosal innate immunity may differ substantially between sexually active adolescents and adult women. These findings warrant further study and may have significant implications for prevention of sexually transmitted infections in adolescent females. PMID:22808157

    Male-perpetrated female-directed violence (FDV) may be associated with greater sexual access to a female. Accordingly, FDV is expected to be associated with greater copulation frequency. Research on nonhuman primates affirms this hypothesis, but no previous research has investigated this relationship in humans (Homo sapiens). The current research tests the hypothesis that FDV is associated with in-pair copulation frequency and, thus, may function as a form of sexual coercion. It was predicted that men who perpetrate FDV will secure more in-pair copulations than men who do not perpetrate violence (Prediction 1a), and that average monthly rates of FDV would positively correlate with in-pair copulation frequency (Prediction 1b). Male participants (n = 355) completed a survey, reporting limited demographic information (e.g., age, relationship length), in-pair copulation frequency, and history of physical violence perpetration. As predicted, violent men secured more in-pair copulations, on average, than nonviolent men, and monthly rates of violence positively correlated with in-pair copulation frequency. In humans, as in nonhuman primates, FDV by males may facilitate greater sexual access to a female. We discuss the implications of the current research for an evolutionary perspective on partner violence, and draw on research on nonhuman primates to highlight profitable avenues of research on FDV in humans.

    Law enforcement detectives who work with traumatized individuals, especially children who were victims of sexual abuse or assault, are likely to experience job-related emotional distress. The purpose of this study was to examine the relations among compassion fatigue, probable PTSD symptoms, and personal relationship satisfaction, including communication and sexual satisfaction, in a sample of 47 male and female detectives. Responses to the administered questionnaires indicated a relation between compassion fatigue symptoms and probable PTSD symptoms. There also were compelling gender differences. For example, for male detectives, open communication with their spouse or significant other was negatively correlated with burnout, indicating the more open the communication, the lower the reported burnout. However for female detectives there was a negative correlation between open communication with spouse or significant other and compassion satisfaction, suggesting that more open communication was related to lower levels of satisfaction with their ability to be a professional caregiver Furthermore, although stepwise regression analysis indicated that years of service as a detective is independently associated with sexual desire, female detectives evidenced less sexual desire and more difficulty with sexual functioning than did male detectives. Implications of these preliminary findings are discussed and limitations addressed.

  12. Sexual cooperation and conflict in butterflies: a male-transferred anti-aphrodisiac reduces harassment of recently mated females.

    Sexual selection theory predicts that the different selection pressures on males and females result in sexual conflict. However, in some instances males and females share a common interest which could lead to sexual cooperation. In the pierid butterfly Pieris napi the male and the recently mated female share a common interest in reducing female harassment by other males soon after mating. Here we show that P. napi males transfer an anti-aphrodisiac to the female at mating, methyl-salicylate (MeS), which is a volatile substance which mated females emit when courted and which makes males quickly abandon them. A 13C-labelling experiment demonstrated that only males synthesize MeS. The effect of this antiaphrodisiac is so strong that most males will refrain from mating with virgin females to whom MeS has been artificially applied. In P. napi, males also transfer nutrients to females at mating. This increases female fecundity and longevity and so females benefit from remating. Hence, sexual cooperation gradually turns to conflict. Future research is required to reveal which sex controls the gradual decrease in the MeS titre which is necessary for allowing mated females to regain attractiveness and remate.

    Although increasing attention has been paid to plant adaptation to soil heavy metal contamination, competition and neighbor effects have been largely overlooked, especially in dioecious plants. In this study, we investigated growth as well as biochemical and ultrastructural responses of Populus cathayana Rehder females and males to cadmium (Cd) stress under different sexual competition patterns. The results showed that competition significantly affects biomass partitioning, photosynthetic capacity, leaf and root ultrastructure, Cd accumulation, the contents of polyphenols, and structural and nonstructural carbohydrates. Compared with single-sex cultivation, plants of opposite sexes exposed to sexual competition accumulated more Cd in tissues and their growth was more strongly inhibited, indicating enhanced Cd toxicity under sexual competition. Under intrasexual competition, females showed greater Cd accumulation, more serious damage at the ultrastructural level and greater reduction in physiological activity than under intersexual competition, while males performed better under intrasexual competition than under intersexual competition. Males improved the female microenvironment by greater Cd uptake and lower resource consumption under intersexual competition. These results demonstrate that the sex of neighbor plants and competition affect sexual differences in growth and in key physiological processes under Cd stress. The asymmetry of sexual competition highlighted here might regulate population structure, and spatial segregation and phytoremediation potential of both sexes in P. cathayana growing in heavy metal-contaminated soils.

    The endogenous opioid system has been implicated in sexual behavior, palatable intake, fear, and anxiety. The present study examined whether ovariectomized female transgenic preproenkephalin-knockout (PPEKO) mice and their wild-type and heterozygous controls displayed alterations in fear and anxiety paradigms, sucrose intake, and lordotic behavior. To examine stability of responding, three squads of the genotypes were tested across seasons over a 20-month period. In a fear-conditioning paradigm, PPEKO mice significantly increased freezing to both fear and fear + shock stimuli relative to controls. In the open field, PPEKO mice spent significantly less time and traversed significantly less distance in the center of an open field than wild-type controls. Further, PPEKO mice spent significantly less time and tended to be less active on the light side of a dark-light chamber than controls, indicating that deletion of the enkephalin gene resulted in exaggerated responses to fear or anxiety-provoking environments. These selective deficits were observed consistently across testing squads spanning 20 months and different seasons. In contrast, PPEKO mice failed to differ from corresponding controls in sucrose, chow, or water intake across a range (0.0001-20%) of sucrose concentrations and failed to differ in either lordotic or female approach to male behaviors when primed with estradiol and progesterone, thereby arguing strongly for the selectivity of a fear and anxiety deficit which was not caused by generalized and nonspecific debilitation. These transgenic data strongly suggest that opioids, and particularly enkephalin gene products, are acting naturally to inhibit fear and anxiety.

    Several studies have explored the association between modes of delivery and postpartum female sexual functioning, although with inconsistent findings. To investigate the impact of mode of delivery on female postpartum sexual functioning by comparing spontaneous vaginal delivery, operative vaginal delivery, and cesarean section. One hundred thirty-two primiparous women who had a spontaneous vaginal delivery, 45 who had an operative vaginal delivery, and 92 who underwent a cesarean section were included in the study (N = 269). Postpartum sexual functioning was evaluated 6 months after childbirth using the Female Sexual Function Index. Time to resumption of sexual intercourse, postpartum depression, and current breastfeeding also were assessed 6 months after delivery. Female Sexual Function Index total and domain scores and time to resumption of sexual intercourse at 6 months after childbirth. Women who underwent an operative vaginal delivery had poorer scores on arousal, lubrication, orgasm, and global sexual functioning compared with the cesarean section group and lower orgasm scores compared with the spontaneous vaginal delivery group (P < .05). The mode of delivery did not significantly affect time to resumption of sexual intercourse. Women who were currently breastfeeding had lower lubrication, more pain at intercourse, and longer time to resumption of sexual activity. Operative vaginal delivery might be associated with poorer sexual functioning, but no conclusions can be drawn from this study regarding the impact of pelvic floor trauma (perineal laceration or episiotomy) on sexual functioning because of the high rate of episiotomies. Overall, obstetric algorithms currently in use should be refined to decrease further the risk of operative vaginal delivery. Copyright © 2016. Published by Elsevier Inc.

  2. Do females pay attention to secondary sexual coloration in vervet monkeys ( Chlorocebus aethiops)?

    Several primate species show sexual dichromatism with males displaying conspicuous coloration of the pelage or skin. Studies of scrotal coloration in male vervet monkeys ( Chlorocebus aethiops) suggest that it is an important intrasexual signal, with relatively dark, colourful males dominating paler males. To date, no studies have examined the influence of male colour on intersexual social interactions in vervet monkeys. The primary goal of the present study was to evaluate whether female vervet monkeys attend to male coloration. We experimentally introduced females, housed with either “pale” or “dark” males, to stimulus males whose scrota were pale, dark, or pale but painted to look dark. Overall, during introductions, females did not differ in time spent directing affiliative behaviour toward pale, dark, and painted males; however, females, permanently housed with dark males, spent significantly more time directing affiliative behaviour toward pale than painted males. When the stimulus male was pale, affiliative exchanges between males and females were longer than when the stimulus male was painted. Home male colour was not related to female-initiated aggression. Home male colour was also not related to male-initiated aggression, although painted stimulus males were more likely to initiate aggression than pale stimulus males. These findings lead us to conclude that females pay attention to male coloration, but do not bias their interactions toward males solely on the basis of natural male coloration.

  3. Exposure to methylphenidate during peri-adolescence affects endocrine functioning and sexual behavior in female Long-Evans rats.

    The present study was designed to test the effects of methylphenidate (MPH) exposure on the maturation of endocrine functioning and sexual behavior. Female rat pups received either MPH (2.0mg/kg, i.p.) or saline twice daily between postnatal days 20-35. This period of exposure represents the time just prior to puberty as well as puberty onset. Approximately five weeks after the last injection of MPH or saline, female subjects were hormone-primed and tested during their first sexual experience. Subjects were given the choice to interact with a sexually active male or a sexually receptive female rat (i.e., the partner-preference test). The partner-preference paradigm allows us to assess multiple aspects of female sexual behavior. MPH exposure during peri-adolescence delayed puberty and, when mated for the first time, affected sexual behavior (e.g., increased time spent with the male stimulus and decreased the likelihood of leaving after mounts) during the test of partner preference. When monitoring estrous cyclicity, female subjects treated with MPH during peri-adolescence frequently experienced irregular estrous cycles. The results of the present study suggest that chronic exposure to a therapeutic dose of MPH around the onset of puberty alters long-term endocrine functioning, but with hormone priming, increases sensitivity to sexual stimuli.

    This study focused on links between romantic attachment, positive body image, and sexual functioning. Dutch female university students (N = 399) completed an online survey that included self-report items about body appreciation, sexual functioning, and romantic attachment. A proposed conceptual model was tested using structural equation modeling and a good fit to the data was found. Results revealed that attachment avoidance in a romantic context was negatively related to sexual arousal, vaginal lubrication, the ability to reach orgasm, and sexual satisfaction. Attachment anxiety was negatively related to body appreciation which, in turn, was positively related to sexual desire and arousal. Findings indicated that romantic attachment is meaningfully linked to body appreciation and sexual functioning. Therefore, the concept of adult attachment may be a useful tool for the treatment of sexual problems of young women.

    Full Text Available Abstract Background The Nepal Demographic Health Survey (NDHS in 2006 showed that more than half (56% of the women with sexually transmitted infections (STIs, including HIV, in Nepal sought sexual health services. There is no such data for female sex workers (FSWs and the limited studies on this group suggest they do not even use routine health services. This study explores FSWs use of sexual health services and the factors associated with their use and non-use of services. Methods This study aimed to explore the factors associated with utilisation of sexual health services by FSWs in the Kathmandu Valley of Nepal, and it used a mixed-method approach consisting of an interviewer administered questionnaire-based survey and in-depth interviews. Results The questionnaire survey, completed with 425 FSWs, showed that 90% FSWs self-reported sickness, and (30.8% reported symptoms of STIs. A quarter (25% of those reporting STIs had never visited any health facilities especially for sexual health services preferring to use non-governmental clinics (72%, private clinics (50%, hospital (27% and health centres (13%. Multiple regression analysis showed that separated, married and street- based FSWs were more likely to seek health services from the clinics or hospitals. In- depth interviews with 15 FSWs revealed that FSWs perceived that personal, structural and socio-cultural barriers, such as inappropriate clinic opening hours, discrimination, the judgemental attitude of the service providers, lack of confidentiality, fear of public exposure, and higher fees for the services as barriers to their access and utilisation of sexual health services. Conclusion FSWs have limited access to information and to health services, and operate under personal, structural and socio-cultural constraints. The 'education' to change individual behaviour, health worker and community perceptions, as well as the training of the health workers, is necessary.

  6. Independent evolution of sexual dimorphism and female-limited mimicry in swallowtail butterflies (Papilio dardanus and Papilio phorcas).

    Several species of swallowtail butterflies (genus Papilio) are Batesian mimics that express multiple mimetic female forms, while the males are monomorphic and nonmimetic. The evolution of such sex-limited mimicry may involve sexual dimorphism arising first and mimicry subsequently. Such a stepwise scenario through a nonmimetic, sexually dimorphic stage has been proposed for two closely related sexually dimorphic species: Papilio phorcas, a nonmimetic species with two female forms, and Papilio dardanus, a female-limited polymorphic mimetic species. Their close relationship indicates that female-limited polymorphism could be a shared derived character of the two species. Here, we present a phylogenomic analysis of the dardanus group using 3964 nuclear loci and whole mitochondrial genomes, showing that they are not sister species and thus that the sexually dimorphic state has arisen independently in the two species. Nonhomology of the female polymorphism in both species is supported by population genetic analysis of engrailed, the presumed mimicry switch locus in P. dardanus. McDonald-Kreitman tests performed on SNPs in engrailed showed the signature of balancing selection in a polymorphic population of P. dardanus, but not in monomorphic populations, nor in the nonmimetic P. phorcas. Hence, the wing polymorphism does not balance polymorphisms in engrailed in P. phorcas. Equally, unlike in P. dardanus, none of the SNPs in P. phorcas engrailed were associated with either female morph. We conclude that sexual dimorphism due to female polymorphism evolved independently in both species from monomorphic, nonmimetic states. While sexual selection may drive male-female dimorphism in nonmimetic species, in mimetic Papilios, natural selection for protection from predators in females is an alternative route to sexual dimorphism.

    We analyzed the sexual behavior and sexually transmitted diseases (STDs) of street-based female sex workers (SFSWs) of Rajshahi city and examined their socio-demographic profiles. Among the SFSWs attending three drop-in centers (DIC) named PIACT, PROVA, and Suraksha Madhumita in Rajshahi, 150 self-motivated and willing individuals were interviewed through a structured questionnaire to obtain obstetric histories and socio-demographic information. Among these SFSWs, 56.7% were infected with two or more pathogens of STDs, with gonorrhea, chlamydia, herpes, syphilis, and trichomoniasis observed in 23.3, 27.3, 24.0, 17.3, and 20.0%, respectively. We found a strong association between the prevalence of STDs among SFSWs and their socio-demographic profiles. Illiterate and comparatively older SFSWs who spent very little money for health purposes, had larger numbers of children, and used condoms inconsistently were observed to be at higher risk of STDs. These results observed with bivariate analysis were also confirmed by logistic regression analysis.

  10. Coevolution of female and male genital components to avoid genital size mismatches in sexually dimorphic spiders.

    In most animal groups, it is unclear how body size variation relates to genital size differences between the sexes. While most morphological features tend to scale with total somatic size, this does not necessarily hold for genitalia because divergent evolution in somatic size between the sexes would cause genital size mismatches. Theory predicts that the interplay of female-biased sexual size dimorphism (SSD) and sexual genital size dimorphism (SGD) should adhere to the 'positive genital divergence', the 'constant genital divergence', or the 'negative genital divergence' model, but these models remain largely untested. We test their validity in the spider family Nephilidae known for the highest degrees of SSD among terrestrial animals. Through comparative analyses of sex-specific somatic and genital sizes, we first demonstrate that 99 of the 351 pairs of traits are phylogenetically correlated. Through factor analyses we then group these traits for MCMCglmm analyses that test broader correlation patterns, and these reveal significant correlations in 10 out of the 36 pairwise comparisons. Both types of analyses agree that female somatic and internal genital sizes evolve independently. While sizes of non-intromittent male genital parts coevolve with male body size, the size of the intromittent male genital parts is independent of the male somatic size. Instead, male intromittent genital size coevolves with female (external and, in part, internal) genital size. All analyses also agree that SGD and SSD evolve independently. Internal dimensions of female genitalia evolve independently of female body size in nephilid spiders, and similarly, male intromittent genital size evolves independently of the male body size. The size of the male intromittent organ (the embolus) and the sizes of female internal and external genital components thus seem to respond to selection against genital size mismatches. In accord with these interpretations, we reject the validity of the

    The current debate around sexual dysfunctions focuses mostly on the pharmacological regulation of lowered sexual desire in women. The Food and Drug Administration approval of the first drug-Addyi-to treat this condition was preceded by a campaign, in which ethically saturated arguments were used to lobby policy makers. This article provides a critical evaluation of these arguments. In particular, we focus our attention on deceitful and unethical use of moral arguments and concepts. First, we present the context in which hypoactive sexual desire disorder is defined as a serious medical condition, showing how non-medical and non-scientific influences shaped the understanding of the problem. Further, we demonstrate how in current discussions regarding lower sexual interest attention has been shifted from psychosocial to pharmacological solutions and we trace the ethical consequences of such a change. We argue that, in addition to typical detrimental effects of overmedicalisation, there are new serious perils. In particular, we demonstrate that it is highly probable that pharmacologisation of female desire-contrary to the emancipatory declarations of the drug proponents-exerts pressure on women and narrows the range of potential choices they can make. As a result, it is inconsistent with the very idea of free choice.

    China has a large migrant population, including many young unmarried women. Little is known about their sexual behavior, contraceptive use, and risk of unintended pregnancy. 475 unmarried female migrants aged 15-24, working in 1 of 6 factories in 2 districts of Changzhou city, completed an anonymous self-administered questionnaire in May 2012 on demographic characteristics, work and living situation, and health. We examined demographic and migration experience predictors of sexual and contraceptive behavior using bivariate and multivariate regressions. 30.1% of the respondents were sexually experienced, with the average age at first sex of 19 years (standard deviation=3). 37.8% reported using contraception at first sex, 58.0% reported using consistent contraception during the past year, and 28.0% reported having at least 1 unintended pregnancy with all unintended pregnancies resulting in abortion. Those who had had at least 1 abortion reported having on average 1.6 abortions [SD=1] in total. Migrating with a boyfriend and changing jobs fewer times were associated with being sexually experienced. Younger age, less education, and changing jobs more times were associated with inconsistent contraceptive use. These findings demonstrate there is an unmet need for reproductive health education and services where these women work as well as in their hometown communities. This education must begin early to reach young women before they migrate. © Zong et al.

    Sociocultural factors have been shown to be important influencers of sexual health and sexuality. Hence, the aim of our study was to explore the views and experiences of family medicine trainees regarding female sexual dysfunction (FSD) with a focus on the barriers and facilitators towards the initiation of conversation on this topic. A qualitative study design involving semi-structured focus group discussions (FGDs) was conducted with 19 family medicine trainees in Malaysia. The conceptual framework used was based on the Theory of Planned Behavior. Thematic approach was used to analyze the data. Participants perceived FSD as being uncommon and unimportant. According to our participants, pat
