    Sexuality is an important component of emotional and physical intimacy that men and women experience throughout their lives. Research suggesting that a high proportion of men and women remain sexually active well into later life refutes the prevailing myth that aging and sexual dysfunction are inexorably linked. Age-related physiological changes do not render a meaningful sexual relationship impossible or even necessarily difficult. Many of these physiological changes are modifiable. There are various therapeutic options available to patients to achieve maximum sexual capacity in old age. This article reviews the prevalence of sexual activity among older adults, the problems these adults encounter with sexual activity, and the role of the health care professional in addressing these problems. The physiological sex-related changes that occur as part of the normal aging process in men and women are reviewed, as well as the effect of age-related physical and psychological illness on sexual function. The attitudes and perceptions of the media and general public toward sexual activity and aging are summarized. An understanding of the sexual changes that accompany the aging process may help general practitioners and other doctors to give practical and useful advice on sexuality as well as refute the misconception that aging equates to celibacy. A thorough awareness of this aspect of older people's quality of life can raise meaningful expectations for aging patients.

    Full Text Available Aim. The purpose of this research was to explore the subject of sexual activity in the Polish population, with special focus on age and gender differences, and sexual infidelity. Sexual activity is one of the basic factors in initiating and maintaining relationships. On the one hand, sexual activity enables us to meet natural needs and maintain an intimate relationship with another human being; on the other, it may allow us to overcome loneliness and social isolation by providing the opportunity to express feelings of closeness and unity. Material and method. The research was conducted on a representative group of 3,200 Poles aged between 15–49, with the support of a well-known Polish research company – TNS OBOP. Face-to-face and Pencil and Paper (PAPI interviews were carried out. Results. The results focus on two main issues: the age and motives of sexual initiation among teenagers (with a significant percentage starting their sexual activity at the age of 15, and the quality of the sexual lives of adults (average number of sexual partners, sexual infidelity and sexual satisfaction. Conclusion. There is dependence between the type of relationship and the performance or non-performance of sexual activity, as well as the quality of the relationship. Among both adolescents and adults, remaining in a stable relationship (partnership or marriage promotes loyalty. The performance of sexual goals turns out to be an important mechanism regulating the interpersonal aspects of a relationship, influencing their perception and evaluation.

    This study explored multiple predictors of sexual well-being in a sample of 253 single, sexually active undergraduate females at a public Mid-Atlantic university. Several factors were identified from past research that might impact sexual well-being: casual sex, sexual agency, sexual attitudes, and sexual desire. Of the four factors, only sexual agency and sexual attitudes were found as significant predictors of sexual well-being. The results suggest that -- of single, sexually active undergr...

    This study examined the prevalence and correlates of sexual activity among individuals experiencing their first dysvascular lower extremity amputation. A prospective cohort was recruited from 4 Veterans Affairs Medical Centers. Of 198 potential participants who met inclusion criteria, 113 (57%) agreed to participate within 7 days of amputation (baseline) and 6 weeks, 4 months, and 12 months post-amputation; 105 completed the sexual activity items at baseline. Measures included self-reported frequency of sexual activity; desire for more or less sexual activity; importance of sexual activity to satisfaction with life; Patient Health Questionnaire-9; Locomotor Capability Index-5; pain intensity/frequency; quality of life. Depending on the time period post-amputation, 11%-24% reported engaging in any sexual activity, although a majority indicated that sexual activity is very important to their satisfaction with life. Frequency of sexual activity increased between 6 weeks and 4 and 12 months post-amputation. In univariate analyses, older age was associated with decreased sexual activity at all time points; at 4 and 12 months, greater mobility was associated with increased sexual activity. In multivariable models, mobility was associated with sexual activity at 4 and 12 months; age and race remained associated with sexual activity at 4 and 12 months, respectively. At all time points, frequency and importance of sexual activity were significantly associated with one another. Although a minority of individuals engaged in any sexual activity during the study period, it remained an important factor in overall satisfaction with life. Younger age and improved mobility were associated with increased sexual activity. Rehabilitation specialists are encouraged to address sexuality and, if relevant, incorporate it into rehabilitation goals. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    female adolescents who had avoided sexual activity were more likely to have experienced sexual coercion. The male adolescents who had avoided sexual activity were more religious and likely to have experienced sexual coercion. The male adolescents who had avoided romantic relationships were more sexually distressed and likely to have experienced sexual coercion. No associations were found for romantic avoidance among female adolescents. These results reflect considerable agency in the decision-making of adolescents in intimate contexts. They are discussed in terms of their challenge to current discourses about rampant adolescent sexuality as well as their implications for education and prevention interventions that incorporate personal choice and decision-making into their protocols.

    The purpose of this study is to examine the role of gender, religiosity, sexual activity, and sexual knowledge in predicting attitudes toward controversial aspects of sexuality among Turkish university students. Participants were 162 female and 135 male undergraduate students who were recruited on a volunteer basis from an urban state university in Turkey. The SKAT-A Attitude Scale along with background information form, sexual activities inventory, and sexual knowledge scale were administered to the participants. Simultaneous multiple regression analyses revealed that religiosity, particularly attendance to religious services was the most significant predictor in explaining university students' attitudes toward masturbation, abortion, homosexuality, pornography, and sexual coercion.

  8. Diabetes and sexual dysfunction: current perspectives

    Full Text Available Maria Ida Maiorino,1 Giuseppe Bellastella,1 Katherine Esposito2 1Department of Medical, Surgical, Neurological, Metabolic and Geriatric Sciences, Second University of Naples, Naples, Italy; 2Department of Clinical and Experimental Medicine, Second University of Naples, Naples, Italy Abstract: Diabetes mellitus is one of the most common chronic diseases in nearly all countries. It has been associated with sexual dysfunction, both in males and in females. Diabetes is an established risk factor for sexual dysfunction in men, as a threefold increased risk of erectile dysfunction was documented in diabetic men, as compared with nondiabetic men. Among women, evidence regarding the association between diabetes and sexual dysfunction are less conclusive, although most studies have reported a higher prevalence of female sexual dysfunction in diabetic women as compared with nondiabetic women. Female sexual function appears to be more related to social and psychological components than to the physiological consequence of diabetes. Hyperglycemia, which is a main determinant of vascular and microvascular diabetic complications, may participate in the pathogenetic mechanisms of sexual dysfunction in diabetes. Moreover, diabetic people may present several clinical conditions, including hypertension, overweight and obesity, metabolic syndrome, cigarette smoking, and atherogenic dyslipidemia, which are themselves risk factors for sexual dysfunction, both in men and in women. The adoption of healthy lifestyles may reduce insulin resistance, endothelial dysfunction, and oxidative stress – all of which are desirable achievements in diabetic patients. Improved well-being may further contribute to reduce and prevent sexual dysfunction in both sexes. Keywords: diabetes mellitus, diabetes complications, erectile dysfunction, female sexual dysfunction, lifestyle changes

    Past research has consistently shown that romantic experiences during adolescence affect the nature and quality of romantic relationships during emerging adulthood. However, less is known about the role of adolescent sexual experiences in future sexual and romantic relationships. The current study examined the impact of different forms of sexual activity at age 16 (within a romantic relationship or casual encounters) on the nature and quality of sexual experiences in romantic relationships at age 23. One hundred and forty four (59.7% females) 16 year olds reported on their sexual activity within a romantic relationship or sexual encounters. In addition they reported on the quality of relationships they were involved in and their tendency to suppress emotions (included as an aspect of personality). At age 23 they reported on their romantic and sexual experiences during the past 2 years (number of short lived relationships, numbers of friends with benefits, casual sex encounters) and the quality of their romantic relationships (the duration of their longest relationship, partner support and feelings of certainty in the relationships). Findings showed that the tendency to suppress emotions was associated with lower likelihood to engage in casual sex at age 23. However, greater sexual experience in casual encounters during adolescence was consistently longitudinally associated with different forms of casual sexual encounters and short romantic involvements above and beyond the contribution of personality. In contrast, sexual activity within a romantic relationship predicted only a few indices of the quality of romantic involvement at age 23. The distinctive role of casual sexual activity and sexual activity within a romantic relationship for future sexual and romantic activities is discussed.

    Background It is widely agreed upon that gender is a key aspect of sexuality however, questions remain on how gender exactly influences adolescents’ sexual health. Objective The aim of this research was to study correlations between gender equality attitudes and sexual behavior, sexual experiences and communication about sex among sexually active and non-sexually active adolescents in 2 Latin American countries. Design In 2011, a cross-sectional study was carried out among 5,913 adolescents aged 14–18 in 20 secondary schools in Cochabamba (Bolivia) and 6 secondary schools in Cuenca (Ecuador). Models were built using logistic regressions to assess the predictive value of attitudes toward gender equality on adolescents’ sexual behavior, on experiences and on communication. Results The analysis shows that sexually active adolescents who consider gender equality as important report higher current use of contraceptives within the couple. They are more likely to describe their last sexual intercourse as a positive experience and consider it easier to talk with their partner about sexuality than sexually experienced adolescents who are less positively inclined toward gender equality. These correlations remained consistent whether the respondent was a boy or a girl. Non-sexually active adolescents, who consider gender equality to be important, are more likely to think that sexual intercourse is a positive experience. They consider it less necessary to have sexual intercourse to maintain a relationship and find it easier to communicate with their girlfriend or boyfriend than sexually non-active adolescents who consider gender equality to be less important. Comparable results were found for boys and girls. Conclusions Our results suggest that gender equality attitudes have a positive impact on adolescents’ sexual and reproductive health (SRH) and wellbeing. Further research is necessary to better understand the relationship between gender attitudes and specific SRH

    No head-to-head studies have been conducted with the phosphodiesterase type 5 (PDE5) inhibitors to date. Results of noncomparative studies, however, suggest that tadalafil and vardenafil hydrochloride are at least as effective as sildenafil citrate in improving erections and increasing the number of successful intercourse attempts in men with erectile dysfunction (ED) at all levels of severity. By facilitating a sexual response, PDE5 inhibitors lend naturalness to sexual activity and may permit couples to return to their previous sexual lifestyle. By providing a broader window of opportunity, a longer-acting PDE5 inhibitor such as tadalafil adds to the variety of options currently available in managing ED with PDE5 inhibitors. This option offers increased flexibility by minimizing the need to plan sexual activity; allowing more time for intimacy or romance before sexual intercourse; and reducing the pressure on the patient to perform.

    Little has been published about sexual function in chronic heart failure (CHF) and knowledge among clinicians in this regard is sparse. To review data regarding sexual function and dysfunction in patients with CHF, 2 of the authors (S.A.M. and P.A.U.) independently conducted a literature search using the MEDLINE database. English-language articles and cited bibliographies published between January 1996 and November 2006 were reviewed. Search terms included heart failure or CHF or ventricular dysfunction or heart disease in conjunction with sexual activity, erectile dysfunction, impotence, or sex. Articles were selected for inclusion if they had a primary focus on CHF and sexual function or dysfunction. Critical reviews of the literature, observational studies using self-reported patient surveys, and prospective, blinded, randomized, placebo-controlled trials were included. Articles were not excluded on the basis of patient sample size but were excluded if the article concerned a broad aspect of cardiovascular disease rather than CHF. When properly screened and treated, most patients with CHF can safely engage in sexual activity and be treated for erectile dysfunction with sildenafil, provided that they do not have active ischemia and do not require treatment with nitrates. Clinicians should know the physiological requirements of sexual activity and the impact CHF has on sexual performance. Fear of a cardiac event during intercourse can interfere with patients' ability to perform and enjoy sex, and so it is important that the physician be able to counsel patients with CHF about sexual activity.

    Full Text Available Unintended pregnancy (UP is a significant public health problem. The consistent use of effective contraception is the primary method to prevent UP. We examined the role of childhood sexual and physical violence and current interpersonal violence on the risk of unintended pregnancy among young, urban, sexually active women. In particular, we were interested in examining the role of childhood violence and interpersonal violence while recognizing the psychological correlates of experiencing violence (i.e., high depressive symptoms and low self-esteem and consistent use of contraception. For this assessment, 315 sexually active women living in Philadelphia PA were recruited from family planning clinics in 2013. A self-administered, computer-assisted interview was used to collect data on method of contraception use in the past month, consistency of use, experiences with violence, levels of depressive symptoms, self-esteem and sexual self-efficacy, substance use and health services utilization. Fifty percent of young sexually active women reported inconsistent or no contraception use in the past month. Inconsistent users were significantly more likely to report at least one prior episode of childhood sexual violence and were significantly less likely to have received a prescription for contraception from a health care provider. Inconsistent contraception users also reported significantly higher levels of depressive symptoms and significantly lower levels of self-esteem. The relation between childhood sexual violence and UP remained unchanged in the multivariate models adjusting for self-esteem or depressive symptoms. These findings highlight the long-term consequences of childhood sexual violence, independent of current depressive symptoms and low self-esteem, on consistent use of contraception.

Recently, the hypothesis that optimal sport performance could be influenced by a variety of factors including sexual activity before competition has been investigated. However, few scientific data are available, with the exception of anecdotal reports of individual experiences. The present systematic review focused on the current scientific evidence on the effects of sexual activity on sport performance regardless of sport type. Data were obtained following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, using PubMed/MEDLINE, ISI/Web of Science, the Cochrane Collaboration Database, Cochrane Library, Evidence Database (PEDro), Evidence Based Medicine (EBM) Search review, National Guidelines, ProQuest, and Scopus, all searched from inception further, to broaden the search, no time filter nor language restriction have been applied. Also, the gray literature was mined using Google Scholar. Only relevant scientific articles reporting outcomes of athletic performance after sexual activity were considered. The impact of sexual activity before a sport competition is still unclear, but most studies generally seem to exclude a direct impact of sexual activity on athletic aerobic and strength performance. The most important aspect seems to be the interval from the time of the sports competition that affects negatively the performance if it is shorter than 2 h. There are possible negative effects from some possible concurrent wrong behaviors such as smoking or alcohol abuse. There are no investigations about the effect of masturbation in this context. There is a need to clarify the effects of sexual activity on competition performance. The present evidence suggests that sexual activity the day before competition does not exert any negative impact on performance, even though high-quality, randomized

    Despite the great interest in the study of sexual homicide, little is known about the processes involved in an individual's becoming motivated to sexually kill, deciding to sexually kill, and acting on that desire, intention, and opportunity. To date, no comprehensive model of sexual murdering from the offending perspective has been proposed in the criminological literature. This article incorporates the works of Akers and Cohen and Felson regarding their social learning theory and routine activities theory, respectively, to construct an integrated conceptual offending framework in sexual homicide. This integrated model produces a stronger and more comprehensive explanation of sexual murder than any single theory currently available.

    Full Text Available 1 Faculty of Nursing and Midwifery, Shahed University of Medical Sciences, Tehran, Iran2(Received 2 March, 2009; Accepted 27 May, 2009AbstractBackground and purpose: Longterm breastfeeding is an important factor for women. Reverse effects of breastfeeding regarding sexual activities have been reported. However, the impact of breastfeeding, along with sexual activity of women during postpartum, is a debatable matter. This effect remains unknown in many societies such as Iran. Sexual activity during breastfeeding from women has not been studied. This study was carried out to compare the association of sexual activity of breastfeeding and non-breastfeeding women within 2-6 months after birth.Materials and methods: In this historical cohort study, which was carried out in 2007, the sexual activity of breastfeeding women was compared with 198 bottle-feeds women, who were referred to a public maternity health care center in Tehran. Women were recruited within the age of 20-35, being their first or second child and in 2-6 months after birth. A self-structured questionnaire was used for data collection. Women were interviewed face-to-face by the first author.Results: Of 456 respondents, 258 were currently breastfeeding and 198 were bottle feed. Mean age of the mothers was 27±4.7 years. 28.3% of breastfeeding women and 22.9% of non breastfeeding women had sexual intercourse within the one month of postpartum period. There was no significant difference between the time of resumption of sexual activity and being breastfeed or not (p<0.07. Also, no significant difference was found between breastfeeding and bottle-feed women on sexual desire and satisfaction prior to pregnancy and in postpartum period (p<0.1, p<0.5. In 49/8% of breastfeed and 43.3% of non breastfeed women, sexual desire was decreased and also in 32.6% and 33%, sexual satisfaction was decreased respectively. The orgasm experience did not have a significant difference between the two groups

    The procedure described herein, capitalizes on a knowledge of the relationships between the pelvic viscera, its autonomic innervation and its tissue support. Operative time is shorter, not only because of the presence of a simultaneous second surgical team, but also because the improved exposure and use of bloodless planes facilitates dissection and reduces blood loss. The careful treatment of the cul-de-sac peritoneum helps protect the autonomic innervation of the pelvis, preserving the function of the bladder and sexual response. Preserving the perineal body and obliterating the dead space behind the posterior vaginal wall with the levator ani muscle provides a muscular cushion for the vagina, preserving maximum coital function. For the woman who is sexually active, these are important goals. Her improved sense of well-being following successful surgical therapy of the disease will result in increasing libido, and her successful adaptation to her new condition will be influenced favorably by her ability to function sexually.

    Few studies examine the mechanisms that link body image to sexual satisfaction in women. Using the tenets of objectification theory, this study investigated the relationships between body surveillance, body shame, body self-consciousness during sexual activities, and sexual satisfaction in an ethnically diverse sample of American female college students (N=368), while controlling for relationship status and body mass index. Results based on self-report measures of these constructs suggested that body shame and body self-consciousness during sexual activity were negatively correlated with sexual satisfaction. Additionally, path analysis indicated that body surveillance predicted increased body self-consciousness during sexual activity, partially mediated by body shame. Body self-consciousness, in turn, predicted decreased sexual satisfaction. Overall, study findings highlight the negative consequences of body image concerns for women's sexual satisfaction.

    Past studies that demonstrated that sexual dysfunction is common among women receiving chronic hemodialysis did not distinguish sexual dysfunction/difficulty from sexual inactivity. This study sought to differentiate these in order to elucidate the prevalence of true "sexual dysfunction" in this population. As part of a clinical trial of symptom management strategies in patients receiving chronic hemodialysis, female sexual function was prospectively assessed monthly for 6 months and quarterly thereafter using the Female Sexual Function Index, to which questions were added differentiating sexual dysfunction/difficulty from sexual inactivity. Beginning in month 7, patients were asked three questions about sexual activity, difficulty, and satisfaction monthly. Of the women enrolled in the clinical trial,125 participants completed 1721 assessments between 2009 and 2011. Scores on 574 of 643 (89%) quarterly Female Sexual Function Index assessments were consistent with sexual dysfunction, due largely to sexual inactivity, which was reported on 525 (82%) quarterly assessments. When reported (n=1663), the most frequently described reasons for sexual inactivity were lack of interest in sex (n=715; 43%) and lack of a partner (n=647; 39%), but rarely sexual difficulty (n=36; 2%). When reported (n=1582), women were moderately to very satisfied with their sexual life on 1020 (64%) assessments and on 513 of 671 (76%) assessments in which lack of interest was cited as a reason for sexual inactivity. Women indicated an interest in learning about the causes of and treatment for sexual dysfunction on just 5% of all assessments. Although many women receiving chronic hemodialysis are sexually inactive, few describe sexual difficulty. Most, including those with a lack of interest in sex, are satisfied with their sexual life and few wish to learn about treatment options. These findings suggest that true sexual dysfunction is uncommon in this population and that treatment opportunities

    Both the general public and individual patients expect healthcare providers to be knowledgeable and approachable regarding sexual health. Despite this expectation there are no universal standards or expectations regarding the sexuality education of medical students. To review the current state of the art in sexuality education for North American medical students and to articulate future directions for improvement. Evaluation of: (i) peer-reviewed literature on sexuality education (focusing on undergraduate medical students); and (ii) recommendations for sexuality education from national and international public health organizations. Current status and future innovations for sexual health education in North American medical schools. Although the importance of sexuality to patients is recognized, there is wide variation in both the quantity and quality of education on this topic in North American medical schools. Many sexual health education programs in medical schools are focused on prevention of unwanted pregnancy and sexually transmitted infection. Educational material on sexual function and dysfunction, female sexuality, abortion, and sexual minority groups is generally scant or absent. A number of novel interventions, many student initiated, have been implemented at various medical schools to improve the student's training in sexual health matters. There is a tremendous opportunity to mold the next generation of healthcare providers to view healthy sexuality as a relevant patient concern. A comprehensive and uniform curriculum on human sexuality at the medical school level may substantially enhance the capacity of tomorrow's physicians to provide optimal care for their patients irrespective of gender, sexual orientation, and individual sexual mores/beliefs. © 2013 International Society for Sexual Medicine.

    Full Text Available INTRODUCTION: Sexual transmission of human herpesvirus 8 (HHV8 has been implicated among homosexual men, but the evidence for sexual transmission among heterosexual individuals is controversial. We investigated the role of sexual transmission of HHV8 in a nationally representative sample in Uganda, where HHV8 infection is endemic and transmitted mostly during childhood. MATERIALS AND METHODS: The study population was a subset of participants (n = 2681 from a population-based HIV/AIDS serobehavioral survey of adults aged 15-59 years conducted in 2004/2005. High risk for sexual transmission was assessed by questionnaire and serological testing for HIV and herpes simplex virus 2. Anti-HHV8 antibodies were measured using two enzyme immunoassays targeting synthetic peptides from the K8.1 and orf65 viral genes. The current study was restricted to 2288 sexually active adults. ORs and 95% CIs for HHV8 seropositivity were estimated by fitting logistic regression models with a random intercept using MPLUS and SAS software. RESULTS: The weighted prevalence of HHV8 seropositivity was 56.2%, based on 1302 seropositive individuals, and it increased significantly with age (P(trend<0.0001. In analyses adjusting for age, sex, geography, education, and HIV status, HHV8 seropositivity was positively associated with reporting two versus one marital union (OR:1.52, 95% CI: 1.17-1.97 and each unit increase in the number of children born (OR: 1.04, 95% CI: 1.00-1.08, and was inversely associated with ever having used a condom (OR: 0.64, 95% CI: 0.45-0.89. HHV8 seropositivity was not associated with HIV (P = 0.660 or with herpes simplex virus 2 (P = 0.732 seropositivity. Other sexual variables, including lifetime number of sexual partners or having had at least one sexually transmitted disease, and socioeconomic variables were unrelated to HHV8 seropositivity. CONCLUSION: Our findings are compatible with the conclusion that sexual transmission of HHV8 in

    Objective Limited research has focused on sexuality for those diagnosed with a severe mental illness. We aimed to extend existing work by exploring relationships between mastery (perception of control of one's life and future), sexual self-esteem (perceptions of one's capacity to engage in healthy sexual behavior), sexual attitudes (permissive ideas about sexuality), and perceived importance of relationships/sexuality and number of sexual partners. Methods A secondary analysis of survey data from adult participants living with a severe mental illness (N=401) in the Indiana Mental Health Services and HIV-Risk Study (Perry & Wright, 2006) was conducted. Analysis of covariance (controlling for marital status) compared those with zero partners, one partner, or multiple partners over the past three months on the dependent variables of mastery, sexual self-esteem, sexual attitudes, and perceived importance. Results Participants with more permissive attitudes, greater perceived importance, and higher mastery were more likely to be sexually active with multiple partners. Self-esteem did not differentiate groups. Conclusions and Implications for Practice Given the key role of sexual satisfaction in quality of life and the high rates of sexual risk behavior in this population, it is important that clinicians systematically assess mastery, perceived importance, and attitudes about sexuality when working with consumers diagnosed with a severe mental illness. Individually tailoring existing interventions based on consumers' levels of mastery, related to self-efficacy for implementing changes in life, could improve long-term outcomes for these programs. Future research should examine other constructs that may account for more variance in sexual activity, such as perceptions of risk, intentions for sexual safety, or romantic relationship functioning.

    A description and comparison of sexual activity and function in relation to various gynaecological cancer diagnoses, treatment modalities, age groups, psychological distress and health-related quality of life. Various forms of gynaecological cancer have the potential to negatively influence sexual functioning, but there are few studies that describe and compare sexual activity and functioning according to diagnosis. A descriptive cross-sectional study. The study includes 129 women from an intervention study. The questionnaires addressed sexuality, psychological distress, health-related quality of life and demographics. Disease and treatment characteristics were extracted from medical records. Close to two-thirds of the women were sexually active. However, 54% of the sexually active women reported that they were not satisfied or little satisfied with their sexual activity. About half of the women reported dryness in the vagina, and 41% reported pain and discomfort during penetration. There were no significant differences concerning pleasure and discomfort related to treatment modality, diagnoses or FIGO stage. Health personnel should make a priority of sexuality throughout a patient's cancer treatment and in the follow-up, as sexuality is a vital part of a good life. Since the patients experience relatively low satisfaction with their sexual activity and many report pain during penetration, health personnel need to be sensitive to the woman, her questions, and her needs. Of importance are also the personnel's ability to communicate and their expertise in diagnosing and treating difficulties relating to sexuality. © 2016 The Authors.

  3. Sexual functioning and commitment to their current relationship among breastfeeding and regularly cycling women in Manila, Philippines.

    Escasa-Dorne, Michelle J

    2015-03-01

    This project investigates the relationship between lactation and female sexual functioning and relationship commitment among partnered women in urban Manila. Previous literature suggests that the time after giving birth is often rife with lower sexual functioning and relationship dissatisfaction. Given the important role of caregiving by multiple individuals in humans, the current cross-sectional study suggests that female sexuality may decline immediately after giving birth but then may increase afterwards. Non-cycling, breastfeeding (n = 86); cycling, breastfeeding (n = 48); and nulliparous, regularly cycling (n = 105) women were recruited from neighborhood health centers in Manila to complete questionnaires that assessed sexual functioning and relationship satisfaction, along with demographic variables. Cycling, breastfeeding women report the highest sexual functioning scores and commitment scores. Females undergoing life history trade-offs between mating effort and parenting effort during the postpartum phase may employ a strategy in which they continue investment both in their offspring and in a romantic relationship. Variations in self-reported sexual functioning, level of commitment in a relationship, and love toward her current partner may indicate that breastfeeding women engage in sexual activities as part of a relationship maintenance strategy. Cultural and life history factors will serve as a framework for the findings. The current findings suggest women in Manila may experience a post-birth increase in sexual functioning that may be higher than pre-pregnancy levels. Future studies should incorporate a longitudinal component or a memory recall on pre-pregnancy and post-birth sexual functioning levels.

    The present study examined the link between the emotional context of sexual situations and sexual risk, specifically by examining the relationship of teens’ recall of their affective states prior to sex with their sexual risk behaviors and attitudes. Adolescents (ages 13-19) attending therapeutic schools due to emotional and behavioral difficulties (n=247) completed audio computer-assisted self-interviews regarding sexual behavior, including ratings of their emotions prior to last sexual activity. Positive emotions were most commonly endorsed (43-57% of participants), however, significant proportions (8-23%) also endorsed negative emotions prior to last sex. Both positive and negative emotions were significantly related to risk attitudes and behavior in regression analyses. The affective contexts of sexual experiences may be important predictors of risk in adolescence. PMID:24558097

    2011-10-01

    While much research has examined sexual problems and dysfunction, far less research has examined intersections between sexual satisfaction and sexual activity, particularly as it relates to social identities. This study utilized secondary analysis of 1,473 women from the National Health and Social Life Survey to examine the way sexual satisfaction and sexual activity are at times misaligned. Using factor and cluster analyses, four groups of women defined by being high or low on satisfaction and activity were predicted by nine demographic variables, including socioeconomic class, racial/ethnic identity, age, marital status, education, sexual identity, geographical "coming of age" location, employment status, and number of children. Results showed that lower status women (women of color, working-class women, younger women, less educated women, women who worked full-time) reported low satisfaction and high activity. Women who reported high satisfaction and low activity represented the largest cluster of women, indicating that more women reported a disjuncture between satisfaction and activity than did those reporting a match between satisfaction and activity. Implications for clinical, sexuality, and social identity literatures are discussed.

    Cognitive appraisals about sex may represent an important component of the maintenance and treatment of hypersexuality, but they are not currently represented in conceptual models of hypersexuality. Therefore, we validated a measure of maladaptive cognitions about sex and examined its unique ability to predict hypersexuality. Qualitative interviews with a pilot sample of 60 highly sexually active gay and bisexual men and expert review of items yielded a pool of 17 items regarding maladaptive cognitions about sex. A separate sample of 202 highly sexually active gay and bisexual men completed measures of sexual inhibition and excitation, impulsivity, emotional dysregulation, depression and anxiety, sexual compulsivity, and a measure of problematic hypersexuality. Factor analysis confirmed the presence of three subscales: perceived sexual needs, sexual costs, and sexual control efficacy. Structural equation modeling results were consistent with a cognitive model of hypersexuality whereby magnifying the necessity of sex and disqualifying the benefits of sex partially predicted minimized self-efficacy for controlling one's sexual behavior, all of which predicted problematic hypersexuality. In multivariate logistic regression, disqualifying the benefits of sex predicted unique variance in hypersexuality, even after adjusting for the role of core constructs of existing research on hypersexuality, AOR = 1.78, 95 % CI 1.02, 3.10. Results suggest the utility of a cognitive approach for better understanding hypersexuality and the importance of developing treatment approaches that encourage adaptive appraisals regarding the outcomes of sex and one's ability to control his sexual behavior.

    Full Text Available PURPOSE: We assessed the relationships between bladder symptoms, demographic, and medical history variables and sexual dysfunction in women with overactive bladder (OAB disorder. MATERIALS AND METHODS: Seventy-eight women diagnosed with OAB completed self-administered questionnaires related to overall heath status, bladder function, and sexual function. Data were compiled for questionnaire responses, and multivariate logistic regression analyses were performed to determine predictors of sexual dysfunction. RESULTS: Bothersome bladder symptoms were reported by superscript three 60% of the sample. Sixty-percent of the sample was sexually active in the past month. Difficulty with sexual arousal, orgasm, and sexual enjoyment were reported by about 25% of the women. Sexual partner status was the best predictor of sexual arousal, orgasm, and sexual enjoyment. Menopausal status emerged as an important predictor of arousal and sexual enjoyment. CONCLUSION: The majority of women with symptoms of OAB viewed these symptoms as bothersome. However, the extent of symptom bother did not predict aspects of female sexual dysfunction (FSD. Instead, menopausal and partner status emerged as the best predictors of FSD in our sample.

    This article analyzes how both the Portuguese state and civil society have addressed the AIDS issue, focusing on participation by the lesbian, gay, bisexual, and transsexual community (LGBT) in the struggle against AIDS. The article begins by describing the situation of LGBT individuals in Portugal during the 1990s, when the Portuguese LGBT movement emerged and grew, and then characterizes the evolution of HIV/AIDS in Portugal, analyzing the relationship between civil society and sexuality in general and the situation of the epidemic in the country in particular, considering key facts, nongovernmental organizations, and state initiatives. Special attention is given to the role played by LGBT organizations in the struggle against HIV. Finally, the article reflects on the future of the struggle against both AIDS and discrimination in the 21st century, considering recent events in the country and the guidelines recommended by international policies.

    2012-04-01

    The present study examined 100 lesbian and gay college students and 100 heterosexual students to determine whether group differences exist in frequency of a range of non-erotic cognitive distractions during sexual activity. Non-erotic cognitive distraction is a descriptive term for both self-evaluative cognitions related to physical performance and body image concerns, as well as additional cognitive distractions (e.g., contracting an STI or emotional concerns) during sexual activity. Participants were matched on gender (96 males and 104 females), age, and ethnicity, and completed questionnaires assessing frequency of non-erotic cognitive distractions during sexual activity, as well as measures of additional variables (trait and body image anxiety, attitudes toward sexual minorities, self-esteem, and religiosity). Results indicated that sexual minorities experienced significantly more cognitive distractions related to body image, physical performance, and STIs during sexual activity than heterosexuals. Regarding gender, men reported more distractions related to STIs than women. Interaction effects were observed between sexual orientation and gender for body image-, disease-, and external/emotional-based distractions. Implications of these findings are discussed.

    Abstract Introduction Type 2 diabetes negatively impacts sexual health. Only limited information is available regarding sexual health among sexually inactive patients with type 2 diabetes. Aim The aim of this study was to examine the prevalence of sexual concerns among sexually active and sexually inactive men and women with type 2 diabetes and of sexual dysfunction (SD) among sexually active. Methods Data from the Anglo–Danish–Dutch Study of Intensive Treatment in People with Screen‐Detected Diabetes in Primary Care‐Denmark study was used. A total of 1,170 Danish patients with screen‐detected type 2 diabetes attended a health examination, including assessment of sexual concerns using self‐report questionnaires and of SD using the Female Sexual Function Index (FSFI‐R) and the International Index of Erectile Function (IIEF‐5) instruments. Main Outcome Measures The main outcome measures used regarding sexual concerns are the following: prevalence of failure to fill sexual needs, of experiencing sexual distress, finding it important to have a good sexual life, and additionally, prevalence of SD. Results Data regarding sexual activity status during the last 12 months were available among 583 men and 377 women. Seventeen percent of men and 47% of women reported to be sexually inactive, among whom 57% of men and 42% of women reported failure to fill sexual needs; 31% of men and 10% of women that it was important to have a good sexual life, and 32% of men and 11% of women that they were experiencing sexual distress. Around half of men and women were excluded from the SD analysis, mainly because of reporting lack of sexual intercourse during the last 4 weeks. Among those included, 54% of men and 12% of women were found to have SD. Conclusions Sexual inactivity is highly prevalent among middle‐aged and older men and women with early type 2 diabetes and these patients often have sexual concerns. The high exclusion rates when assessing SD using the FSFI

    Full Text Available Introduction: Sexual activity can affect prostate cancer pathogenesis in a variety of ways; including the proposed high androgen status, risk of sexually transmitted infections and the potential effect of retained carcinogens within the prostatic cells. Methods: PubMed review of all publications concerning sexual activity and the risk of prostate cancer was done by two researchers. Results: Few publications could be detected and data were classified as a prostate cancer risk in association with either heterosexual or homosexual activities. Conclusion: Frequent ejaculation seems to be protective from the development of prostate cancer. Multiple sexual partners may be protective from prostate cancer, excluding the risk of sexually transmitted infections. Homosexual men are at a greater risk for the diagnosis of prostate cancer.

    Examined self-esteem and sexuality in 141 male and 172 female adolescents. Found no differences in self-esteem of males versus females. Sexual activity or virginity was not related to self-esteem for either gender. Pregnant teenagers did not have different self-esteem levels from nonpregnant. Males who had fathered a child had lower self-esteem…

    Objective compare quality of life (QoL) and sexual functioning between sexually active ovarian cancer survivors and healthy women. Methods A cross-sectional study was performed in 103 successfully treated ovarian cancer survivors and 220 healthy women. All women had engaged in sexual activity within the previous 3 months, and ovarian cancer survivors were under surveillance after primary treatment without evidence of disease. QoL and sexual functioning were assessed using three questionnaires; the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), Ovarian Cancer Module (EORTC QLQ-OV28), and the Female Sexual Function Index (FSFI). Propensity score matching was used to adjust covariates between the ovarian cancer survivor and healthy women groups. In total, 73 ovarian cancer survivors and 73 healthy women were compared. Results Poorer social functioning (mean, 82.4 vs. 90.9; p=0.010) and more financial difficulties (mean, 16.4 vs. 7.8; p=0.019) were observed among ovarian cancer survivors than among healthy women. Sexuality, both in terms of desire, arousal, lubrication, orgasm, satisfaction, and pain and in terms of interest in sex, sexual activity, and enjoyment of sex (EORTC QLQ-OV28) were similar between the groups. However, vaginal dryness was more problematic in ovarian cancer survivors, with borderline statistical significance (p=0.081). Conclusion Sexuality was not impaired in ovarian cancer survivors who were without evidence of disease after primary treatment and having sexual activities, compared with healthy women, whereas social functioning and financial status did deteriorate. Prospective cohort studies are needed. PMID:25686396

    Despite indirect evidence linking narcissism to sexual aggression, studies directly examining this relationship have yielded inconsistent results. Likely contributing to such inconsistencies, prior research has used global measures of narcissism not sensitive to whether the components of narcissism are activated in sexual versus non-sexual domains. The current research avoided such problems by using a measure of sexual narcissism to predict sexual aggression. In a sample of 299 men and women, Study 1 validated the Sexual Narcissism Scale, a new sexuality research instrument with four subscales-Sexual Exploitation, Sexual Entitlement, Low Sexual Empathy, and Sexual Skill. Then, in a sample of 378 men, Study 2 demonstrated that sexual narcissism was associated with reports of the frequency of sexual aggression, three specific types of sexual aggression (unwanted sexual contact, sexual coercion, and attempted/completed rape), and the likelihood of future sexual aggression. Notably, global narcissism was unrelated to all indices of sexual aggression when sexual narcissism was controlled. That sexual narcissism outperformed global assessments of narcissism to account for variance in sexual aggression suggests that future research may benefit by examining whether sexual narcissism and other sexual-situation-specific measurements of personality can similarly provide a more valid test of the association between personality and other sexual behaviors and outcomes (e.g., contraceptive use, infidelity, sexual satisfaction).

    This report presents the guidelines for the treatment of individuals with sexually transmitted diseases (STD) that were developed by the STD Study Group "GIRVE" of the Società Italiana di Dermatologia e Venereologia (Italian Society of Dermatology and Venerology) in accordance with those developed by the US Centers for Disease Control and Prevention in 1998. The guidelines represent a useful tool for physicians and other health-care providers in preventing and controlling STDs. The guidelines include new recommendations for treating genital herpes and genital warts.

    There is considerable debate over whether adolescent sexual activity is maladaptive and associated with worse mental health outcomes versus a positive developmental milestone that is associated with better mental health outcomes. Although these perspectives are often pitted against one another, the current study employed a more integrative perspective: adolescent sexual activity may be maladaptive in certain contexts, but healthy in other contexts. We investigated whether family support and gender moderated the relation between sexual activity and mental health outcomes in a diverse sample of 519 lesbian, gay, and bisexual (LGB) youth. Specifically, we examined whether youth who engaged in more sexual activity would have fewer depressive symptoms in the context of a more supportive family environment, but more depressive symptoms in the context of a less supportive family environment and whether this effect was stronger for sexual minority girls. Consistent with the sexual health perspective, we found that among girls with more family support, those who engaged in more frequent same-sex sexual contact had lower levels of depressive symptoms. Unexpectedly, we found that among boys with more family support, those who engaged in more frequent same-sex sexual contact had higher levels of depressive symptoms. In contrast, girls and boys with less family support showed no relation between sexual activity and depressive symptoms. Overall, results suggest that context is critical when determining whether same-sex sexual contact among LGB youth should be considered maladaptive or beneficial.

    To study determinants of romantic relationships and sexual activity of young adults with cerebral palsy (CP), focusing on personal and environmental factors. A cohort study was performed with 74 young adults (46 men; 28 women) aged 20-25 years (SD 1.4) with CP (49% unilateral CP, 76% GMFCS level I, 85% MACS level I). All participants were of normal intelligence. Romantic relationships, sexual activity (outcome measures), personal and environmental factors (associated factors) were assessed. Associations were analyzed using logistic regression analyses. More females than males with CP were in a current romantic relationship. Self-esteem, sexual esteem and feelings of competence regarding self-efficacy contributed positively to having current romantic relationships. A negative parenting style contributed negatively. Age and gross motor functioning explained 20% of the variance in experience with intercourse. In addition, sexual esteem and taking initiative contributed significantly to intercourse experience. For young adults with CP personal factors (20-35% explained variances) seem to contribute more than environmental factors (9-12% explained variances) to current romantic relationships and sexual experiences. We advice parents and professionals to focus on self-efficacy, self-esteem and sexual self-esteem in development of young adults with CP. [ • The severity of gross motor functioning contributed somewhat to sexual activities, but not to romantic relationships.• High self-efficacy, self-esteem and sexual self-esteem can facilitate involvement in romantic and sexual relationships for young adults with CP.

  1. Sexual sadism: current diagnostic vagueness and the benefit of behavioral definitions.

    2013-12-01

    The phenomenon of sexual sadism was first scientifically described by Richard von Krafft-Ebing in 1999 as a sexual preference disorder that focuses on the infliction of suffering, pain, or humiliation to achieve sexual gratification. The present article reviews the historical development of the term sexual sadism, including the current descriptive nosology of psychiatric classification. Despite clear definitions that specify the sexual objects, duration, and distress necessary for a disorder, evidence for the diagnostic reliability for sexual sadism in the forensic domain is mixed. We argue that the reliance on the patient's willingness to divulge corresponding violent sexual fantasies is the Achilles' heel of the diagnosis. In an attempt to improve agreement across diagnosticians, we argue for the use of behavioral indicators. We summarize the extant research on the Severe Sexual Sadism Scale (SESAS), which is a file-based observer rating of pertinent crime-scene actions. We conclude that the analysis of crime-scene behavior, as achieved with the SESAS, can provide a useful complement for the clinical diagnosis in forensic psychiatry and psychology.

    Cognitive appraisals about sex may represent an important component of the maintenance and treatment of hypersexuality, but they are not currently represented in conceptual models of hypersexuality. Therefore, we validated a measure of maladaptive cognitions about sex and examined its unique ability to predict hypersexuality. Qualitative interviews with a pilot sample of 60 highly sexually active gay and bisexual men and expert review of items yielded a pool of 17 items regarding maladaptive cognitions about sex. A separate sample of 202 highly sexually active gay and bisexual men completed measures of sexual inhibition and excitation, impulsivity, emotional dysregulation, depression and anxiety, sexual compulsivity, the Hypersexual Disorder Screening Inventory proposed by the American Psychiatric Association’s DSM-5 Workgroup on Sexual and Gender Identity Disorders (2010). Factor analysis confirmed the presence of three subscales: perceived sexual needs, sexual costs, and sexual control efficacy. Structural equation modeling results were consistent with a cognitive model of hypersexuality whereby magnifying the necessity of sex and disqualifying the benefits of sex partially predicted minimized self-efficacy for controlling one’s sexual behavior, all of which predicted problematic hypersexuality. In multivariate logistic regression, disqualifying the benefits of sex predicted unique variance in hypersexuality, even after adjusting for the role of core constructs of existing research on hypersexuality, AOR = 1.78, 95% CI 1.02, 3.10. Results suggest the utility of a cognitive approach for better understanding hypersexuality and the importance of developing treatment approaches that encourage adaptive appraisals regarding the outcomes of sex and one’s ability to control his sexual behavior.

    Sexual economics theory assumes that heterosexual communities can be analyzed as marketplaces in which men offer women resources such as love, respect, money, and commitment in exchange for sex. In response to economic, political, and other disadvantages, women collectively restrict their sexuality to maintain a low supply relative to male demand, thereby ensuring a high price. Hence, we tested the hypothesis that sexual norms and practices would be more restrictive in countries marked by gender inequality than in countries where the genders were more equal. An international online sex survey (N>317,000) yielded four measures of sexual activity, and 37 nations' means on all four measures were correlated with independent (World Economic Forum) ratings of gender equality. Consistent with predictions, relatively high gender equality was associated with more casual sex, more sex partners per capita, younger ages for first sex, and greater tolerance/approval of premarital sex.

    Adolescence is a period when the individual is vulnerable and exposure to sexually implicit/explicit programs on television and internet can influence their sexual behaviour and make them more permissive towards premarital sex, which is known to influence their academic performance. This can be modified by parental discussion on these matters with their children. There have been only few studies from India that have explored such issues therefore this study aimed to explore the impact of television, internet and parental discussion on sexual activity and academic performance. This study was conducted in two co-education schools using a self reporting questionnaire administered to students of class IX-XII. This study evaluated the relation of academic performance, exposure to media such as television & internet to sexual activity & academic performance of the students and the role of parental discussion on these. The study sample size was 586. There is no significant association between the number of hours of watching television per day and academic performance as measured by marks in examinations. Significant positive association was found among boys between sexual contact and average score in academics & unsupervised use of internet. In both genders a significant positive association was found between those watching English serials, movies and increased chances of indulging in sexual activity while a negative relation with those watching Cartoons. There is no significant difference in occurrence of sexual contact in those who discussed sexual matters with parents and those who did not. This being first of it's kind of study from India and a cross sectional study, further prospective and detailed studies are warranted to delineate the interaction of media, parental discussion, academic performance and sexual activity.

    Conclusions: Sexual inactivity is highly prevalent among middle‐aged and older men and women with early type 2 diabetes and these patients often have sexual concerns. The high exclusion rates when assessing SD using the FSFI‐R and IIEF‐5 instruments makes it difficult to draw conclusions regarding the prevalence. Sexual health should be broadly assessed in both sexually active and sexually inactive people with type 2 diabetes. Bjerggaard M, Charles M, Kristensen E, Lauritzen T, Sandbæk A, and Giraldi A.

    2016-03-01

    The current study investigated whether a history of child abuse is a predictor of adult immune status, with unwanted adult sexual experiences as a proximal mediator. Participants included 89 young adult women (M(age) = 19.24) who were classified as having experienced no child abuse, child physical abuse, or child sexual abuse, based upon self-reported victimization history before 14 years of age. Participants also reported on unwanted sexual experiences in young adulthood and provided four saliva samples, which were collected over two consecutive days to determine secretory immunoglobulin A (sIgA). Age and negative life events were considered as covariates. The results indicated that adult sexual victimization partially mediated the relationship between child abuse (physical and sexual) and sIgA. Specifically, child abuse experiences predicted more adult sexual victimization experiences, which in turn predicted lower sIgA levels. These findings support long-term health effects of victimization, and suggest that the influence of child abuse on sIgA may be perpetuated through adult victimization. Prevention efforts should aim to empower child maltreatment survivors with skills to prevent adult re-victimization. By thwarting future unwanted sexual experiences in adulthood, individuals will be better protected from the health impairments associated with early abuse experiences. © The Author(s) 2014.

    The sleep pattern is modified by events occurring during wakefulness. In rats, it has been shown that male sexual behavior has a direct influence on sleeping patterns, increasing slow wave sleep (SWS) duration. On the other hand, the sexual behavior pattern of the male Golden hamster differs from the copulatory pattern of male rats. Male hamsters copulate faster and they do not display the motor inhibition observed in rats after each ejaculation. Moreover, close to exhaustion, hamsters display a behavioral pattern known as Long Intromission, which has been linked to an sexual inhibitory process. The present study was performed to determine the effects of male sexual activity on the sleep pattern in hamsters. Subjects were allowed to copulate for 30 and 60 min. In addition, the effect of locomotor activity was also assessed. The results show that male sexual behavior induced a significant increase of SWS II, with a reduction of wakefulness. No effect was observed on REM sleep. Locomotor activity produced only a slight effect on sleep. The results are discussed in terms of the similarities between the effects observed after sexual behavior on sleep in rats and hamsters, despite the substantial differences in the behavioral pattern.

    Introduction Despite the aging of the population, there is limited data available about sexual life and behaviours among of postmenopausal and late postmenopausal women. Aim of the study was to assess the prevalence of sexual dysfunction, behaviours, and preferences in the Polish population in 2015. Material and methods This observational survey study involved 538 women, of whom 220 were over 50 years old. The main focus was on the differences and changes between older age groups, mainly 50-59 years and over 60 years. Results For 80.9% of the women above 50 years old, sex played at least a moderately important role in life. Sex was definitely important and very important for 40.45% of them. Most women over 50 years old (65.5%) were sexually active. Regardless of age, the respondents were more likely to have sexual intercourse several times a month. Less than half of the women over 50 years old (42.7%) realised their sexual fantasies. Women in the group of 50-59 years old statistically less often than younger women declared that the frequency of intercourse they had was too small. There was a statistical tendency showing that women up to 49 years old declared more sexual problems than older women. Women over 50 years old reported fewer problems in comparison to younger women, e.g. less often they claimed that sex is not pleasurable (p = 0.064). Conclusions The prevalence of sexual activity declines with age, yet a substantial number of woman engage in vaginal intercourse, oral sex, and masturbation even past the seventh decade of life.

    To investigate whether past-30 day illicit drug use among sexual minority youth was more common in neighborhoods with a greater prevalence of hate crimes targeting lesbian, gay, bisexual, and transgender (LGBT, or sexual minority) individuals. We used a population-based survey of public school youth in Boston, Massachusetts, consisting of 1292 9th-12th grade students from the 2008 Boston Youth Survey Geospatial Dataset (sexual minority n=108). Data on LGBT hate crimes involving assaults or assaults and battery between 2005 and 2008 were obtained from the Boston Police Department and linked to youths' residential address. Youth reported past-30 day use of marijuana and other illicit drugs. Wilcoxon-Mann-Whitney tests and corresponding p-values were computed to assess differences in substance use by neighborhood-level LGBT assault hate crime rate among sexual minority youth (n=103). The LGBT assault hate crime rate in the neighborhoods of sexual minority youth who reported current marijuana use was 23.7 per 100,000, compared to 12.9 per 100,000 for sexual minority youth who reported no marijuana use (p=0.04). No associations between LGBT assault hate crimes and marijuana use among heterosexual youth (p>0.05) or between sexual minority marijuana use and overall neighborhood-level violent and property crimes (p>0.05) were detected, providing evidence for result specificity. We found a significantly greater prevalence of marijuana use among sexual minority youth in neighborhoods with a higher prevalence of LGBT assault hate crimes. These results suggest that neighborhood context (i.e., LGBT hate crimes) may contribute to sexual orientation disparities in marijuana use. Copyright © 2013 Elsevier Ireland Ltd.

    A 46-year-old man with early gastric cancer at the gastric antrum underwent an F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)-computer tomography (CT) scan for staging. No definite abnormal FDG uptake of the stomach was shown. Incidentally, variable FDG uptake at the bilateral serratus muscles, abdominal muscles and muscles of both thighs (Fig. 1) was observed. He had no significant past medical history except recently diagnosed stomach cancer. On personal interview, he described having had sexual activity the night before the F-18 FDG PET/CT scan, although he was aware of needing to avoid physical activity before a PET scan. The F-18 FDG PET/CT scan was done at 2:00 p.m. Therefore, the hypermetabolism of individual skeletal muscles following sexual activity lasted over 12 h. This case illustrates the hypermetabolism of skeletal muscles following sexual activity as a normal variation.

    Although the majority of adulthood sexual violence involves a male perpetrator and a female victim, there is also substantial evidence that members of both genders can be victims and perpetrators of sexual violence. As an alternative to viewing sexual violence within gender-specific terms, we advocate for the use of a gender inclusive conceptualization of sexual aggression that takes into account the factors that contribute to sexual victimization of, and victimization by, both men and women. The goal of the current review is to examine the need and importance of a gender inclusive conceptualization of sexual violence and to discuss how compatible our current theories are with this conceptualization. First, we examine evidence of how a gender-specific conceptualization of sexual violence aids in obscuring assault experiences that are not male to female and how this impacts victims of such violence. We specifically discuss this impact regarding research, law, public awareness, advocacy, and available victim treatment and resources. Next, we provide an overview of a number of major sexual violence theories that are relevant for adult perpetrators and adult victims, including neurobiological and integrated biological theories, evolutionary psychology theory, routine activity theory, feminist theory, social learning and related theories, typology approaches, and integrated theories. We critically examine these theories' applicability to thinking about sexual violence through a gender inclusive lens. Finally, we discuss further directions for research, clinical interventions, and advocacy in this area. Specifically, we encourage sexual violence researchers and clinicians to identify and utilize appropriate theoretical frameworks and to apply these frameworks in ways that incorporate a full range of sexual violence.

    The study sought to establish university students' perceptions of risk of HIV infections. A cross-sectional survey was conducted on 345 sexually active students at two universities in Zimbabwe (one state and one private). Results revealed that above a quarter of the respondents felt at risk of getting HIV due to their regular partners' sexual behaviours and more than half felt at risk of getting HIV due to their casual partners' sexual behaviours. In addition, a third of the respondents acknowledged the HIV risk due to their own sexual behaviours. More state university respondents felt exposed to HIV infections due to own sexual behaviours than their private university counterparts. Despite these revelations, only 66.56% had earlier thought of their chances of getting infected with HIV. Personal HIV risk perceptions were low, reported by 27.76% of the sexually active respondents. Almost all respondents described their fellows' sexual behaviours as either risky or very risky.

  16. Excessive sexual activities among male clients in substance abuse treatment. An interview study.

    Full Text Available Purpose: The co-occurrence of substance abuse and excessive sexual activities is acknowledged in research and treatment practice. Men seem particularly at risk for developing excessive sexual activities. Excessive sexual activities complicate substance abuse treatment, and clients with such co-occurring difficulties have considerable treatment needs. It is therefore considered important to investigate how male clients who had enacted excessive sexual activities, perceive their excessive sexual activities, and themselves. Design: Interviews were performed with five male clients in substance abuse treatment, who had enacted excessive sexual activities. The interviews concerned the participants’ perception of themselves and how they came to enact excessive sexual activities. The interviews were analyzed using thematic analysis. Results: Two major themes were identified. One theme concerned overwhelming shame and difficulties to discuss sexuality in treatment. The second theme concerned how perceptions about masculinity had influenced sexual activities. Sexuality was described as an absent topic in their previous and ongoing treatment, and the participants described a need to discuss sexuality. Implications: It seems important that future studies investigate how excessive sexual activities might be identified and handled in treatment. It also seems important to investigate how gender-perceptions might influence excessive sexual activities. As a suggestion, practitioners should address sexuality, shame and perceptions about gender during treatment. Keywords: Excessive sexual activities; Interview study; Masculinity; Shame; Substance abuse; Treatment

    The aim of this study was to assess the perceived impact of ankylosing spondylitis (AS) on sexual activity within Moroccan men and to identify the associations with demographic, psychological status, quality of sleep, and disease-related variables. A total of 110 patients with a confirmed diagnosis of AS according to the modified New York classification criteria were invited to participate in the study. Patients completed a questionnaire, which also included questions relating to the impact of AS on their sexual function, socio-demographic and clinical characteristics. The patient sample comprised 110 men. The mean age of patients was 38.5 ± 12.6 years. Among the 110 patients, only 73 (67 %) have already had sexual activity. In this group of patients, 32 (44 %) were unsatisfied, 30 (41 %) reported erectile dysfunction, and 28 (38.4 %) had orgasmic trouble. Multivariate analysis showed that fatigue and sleep disturbance were independently associated with erectile dysfunction. This study suggests that AS in men seems to impact on sexual lives. Fatigue and sleep disturbance were independently associated with perceived problems with sexual activity.

    Full Text Available Background Premarital sexual relationships could harm youth’s health in terms of sexually transmitted infections or increased risk of unprotected sexual behaviors. Sexual abstinence has been recommended to prevent young adolescents from adverse outcomes of premarital sexual relationships. Objectives The aim of this study was to explore the viewpoints of sexually active single women about premarital sexual relationships in the Iranian context. Patients and Methods In this qualitative study, we recruited 41 young women aged 18 to 35 years. Data were collected using focus group discussions and individual interviews. We employed conventional content analysis to analyze the data. Multiple data collection methods, maximum variation sampling, and peer checks were applied to enhance the reliability of the findings. Results Eight themes emerged from the data analysis: ‘acceptance of sexual contact in the context of opposite-sex relationships, ‘sexual activity as a guarantee for keeping the boyfriend in the relationship’, ‘premarital sexual relationship as an undeniable personal right’, ‘having successful marriage in spite of premarital sexual relationships’, ‘virginity as an old fashioned phenomenon’, ‘love as a license for premarital sexual behaviors’, ‘goal-oriented relationship as a license for premarital sexual behaviors’, and ‘experiencing premarital sexual relationships in order to gain perfection’. Conclusions Results of this study could be applied to designing interventions, such as promotion of preventive beliefs or educational programs regarding premarital sexual relationships in conservative societies. These interventions could start within families and continue at schools and universities.

    Adolescents with hemoglobinopathies need daily chelation therapy with drugs which are known or suspected to be teratogenic. The prevention of fetal exposure to such drugs is therefore a major task for health professionals caring for these patients. We describe a pilot program aiming to prevent pregnancy among sexually active adolescents treated with iron chelators in Toronto. Most of them had normal response to GnRH, suggesting endocrinologic fertility, and unlike the literature concerning their healthy peers, all sexually active patients in this study reported use of at least one form of contraception.

    Novel current-mode active filter circuits using current-conveyors are presented. The proposed circuits can realize all standard second-order filter functions. The circuits enjoy high output impedances and can, therefore, be easily cascaded to produce higher order filters. Moreover, the realized filter function can be easily programmed using at most a 13-bit digital number without changing the circuit topology.

    Full Text Available Abstract Background The prostate is a key gland in the sexual physiology of male mammals. Its sensitivity to steroid hormones is widely known, but its response to prolactin is still poorly known. Previous studies have shown a correlation between sexual behaviour, prolactin release and prostate physiology. Thus, here we used the sexual behaviour of male rats as a model for studying this correlation. Hence, we developed experimental paradigms to determine the influence of prolactin on sexual behaviour and prostate organization of male rats. Methods In addition to sexual behaviour recordings, we developed the ELISA procedure to quantify the serum level of prolactin, and the hematoxilin-eosin technique for analysis of the histological organization of the prostate. Also, different experimental manipulations were carried out; they included pituitary grafts, and haloperidol and ovine prolactin treatments. Data were analyzed with a One way ANOVA followed by post hoc Dunnet test if required. Results Data showed that male prolactin has a basal level with two peaks at the light-dark-light transitions. Consecutive ejaculations increased serum prolactin after the first ejaculation, which reached the highest level after the second, and started to decrease after the third ejaculation. These normal levels of prolactin did not induce any change at the prostate tissue. However, treatments for constant elevations of serum prolactin decreased sexual potency and increased the weight of the gland, the alveoli area and the epithelial cell height. Treatments for transient elevation of serum prolactin did not affect the sexual behaviour of males, but triggered these significant effects mainly at the ventral prostate. Conclusion The prostate is a sexual gland that responds to prolactin. Mating-induced prolactin release is required during sexual encounters to activate the epithelial cells in the gland. Here we saw a precise mechanism controlling the release of prolactin

The general idea that HSDD is a sexual dysfunction difficult to treat is due to the large number of potential causes and contributing factors. Indeed, a balanced approach comprising both biological and psycho-relational factors is mandatory for accurate diagnosis and tailored management in clinical practice. There are currently no approved pharmacological treatments for premenopausal women with HSDD, while transdermal testosterone is approved in Europe for postmenopausal women who experience HSDD as a result of a bilateral oophorectomy. Even though the role of sex hormones in modulating the sexual response during the entire reproductive life span of women is crucial, a better understanding of the neurobiological basis of sexual desire supports the idea that selective psychoactive agents may be proposed as nonhormonal treatments to restore the balance between excitatory and inhibitory stimuli leading to a normal sexual response cycle. We conclude that the ideal clinical approach to HSDD remains to be established in term of efficacy and safety, and further research is needed to develop specific hormonal and nonhormonal pharmacotherapies for individualized care in women.Keywords: sexual desire, distress, testosterone, psychoactive drugs, psychosexual interventionsErratum for this paper has

    BACKGROUND: Sexual life may be impaired by pain during sexual activity in patients with inguinal hernia. On the other hand, inguinal hernia repair has also been reported to cause sexual dysfunction in terms of pain during sexual activity and ejaculation. The primary aim of this study...... was to estimate the prevalence of pain during sexual activity before and after laparoscopic inguinal hernia repair, and the secondary, to describe pain location, frequency of pain during sexual activity, and to which degree sexual life was affected by the pain. Furthermore, to examine whether preoperative pain...... during sexual activity was a risk factor for postoperative pain during sexual activity. METHODS: A prospective questionnaire study before and 6 months after hernia repair was conducted. Men (age 18-85 years) undergoing laparoscopic inguinal hernia repair were included. RESULTS: In total, 160 men were...

    This study examined sexual orientation change efforts (SOCE) by 1,612 individuals who are current or former members of the Church of Jesus Christ of Latter-day Saints (LDS). Data were obtained through a comprehensive online survey from both quantitative items and open-ended written responses. A minimum of 73% of men and 43% of women in this sample attempted sexual orientation change, usually through multiple methods and across many years (on average). Developmental factors associated with attempts at sexual orientation change included higher levels of early religious orthodoxy (for all) and less supportive families and communities (for men only). Among women, those who identified as lesbian and who reported higher Kinsey attraction scores were more likely to have sought change. Of the 9 different methods surveyed, private and religious change methods (compared with therapist-led or group-based efforts) were the most common, started earlier, exercised for longer periods, and reported to be the most damaging and least effective. When sexual orientation change was identified as a goal, reported effectiveness was lower for almost all of the methods. While some beneficial SOCE outcomes (such as acceptance of same-sex attractions and reduction in depression and anxiety) were reported, the overall results support the conclusion that sexual orientation is highly resistant to explicit attempts at change and that SOCE are overwhelmingly reported to be either ineffective or damaging by participants.

  10. Energy expenditure during sexual activity in young healthy couples.

    Directory of Open Access Journals (Sweden)

    Julie Frappier

    Full Text Available OBJECTIVE: To determine energy expenditure in kilocalories (kcal during sexual activity in young healthy couples in their natural environment and compare it to a session of endurance exercise. METHODS: The study population consisted of twenty one heterosexual couples (age: 22.6 ± 2.8 years old from the Montreal region. Free living energy expenditure during sexual activity and the endurance exercise was measured using the portable mini SenseWear armband. Perceived energy expenditure, perception of effort, fatigue and pleasure were also assessed after sexual activity. All participants completed a 30 min endurance exercise session on a treadmill at a moderate intensity. RESULTS: Mean energy expenditure during sexual activity was 101 kCal or 4.2 kCal/min in men and 69.1 kCal or 3.1 kCal/min in women. In addition, mean intensity was 6.0 METS in men and 5.6 METS in women, which represents a moderate intensity. Moreover, the energy expenditure and intensity during the 30 min exercise session in men was 276 kCal or 9.2 kCal/min and 8.5 METS, respectively and in women 213 kCal or 7.1 kCal/min and 8.4 METS, respectively. Interestingly, the highest range value achieved by men for absolute energy expenditure can potentially be higher than that of the mean energy expenditure of the 30 min exercise session (i.e. 306.1 vs. 276 kCal, respectively whereas this was not observed in women. Finally, perceived energy expenditure during sexual activity was similar in men (100 kCal and in women (76.2 kCal when compared to measured energy expenditure. CONCLUSION: The present study indicates that energy expenditure during sexual activity appears to be approximately 85 kCal or 3.6 kCal/min and seems to be performed at a moderate intensity (5.8 METS in young healthy men and women. These results suggest that sexual activity may potentially be considered, at times, as a significant exercise.

    Physical activity has long been associated with better sexual function. This study investigated the effects of moderate swimming exercise on the copulatory behavior of sexually potent male rats. Two sets of sexually potent male rats -highly active and moderately active- were identified depending on baseline sexual activity. Each of the two sets of rats was further randomly divided into two groups (swimming and sedentary). There were 16 rats in each of the four study groups (highly active swimming, highly active sedentary, moderately active swimming and moderately active sedentary). The copulatory behavior parameters and serum testosterone levels were measured and compared between the rats of the swimming and sedentary groups following a month long training period in which rats were made to swim for 1 h every alternate day. Swimming significantly improved the sexual performance of highly active rats, as indicated by increased intromission frequency and intromission ratio, compared with the sedentary controls. Swimming improved both sexual desire and performance, as indicated by reduced mount latency and increased intromission ratio, respectively, in swimming moderately active rats compared with the sedentary moderately active controls. Therefore, swimming activity improves the copulatory behavior of both highly active and moderately active male rats.

  12. Differences in Dietary Intake as a Function of Sexual Activity and Hormonal Contraception

    2007-07-01

    Full Text Available As a consequence of the need to downregulate some maternal immune responses so as to tolerate paternal genetic material following conception, the luteal phase of the menstrual cycle is associated with increased susceptibility to infection. Because meat was one of the primary sources of foodborne pathogens throughout our evolutionary history, Fessler (2001 predicted a decrease in meat intake during the luteal phase; the current research provides the first test of this prediction. Based on the assumption that any such behavioral changes would be hormonally mediated, we also investigated the effects of varying levels of exogenous hormones on meat consumption by examining dietary intake in women using hormonal contraceptives. Lastly, because, from a functional perspective, immunomodulation is unnecessary during anovulatory cycles and in women who are not currently sexually active, luteal phase compensatory behavioral prophylaxis was predicted to be absent in these contexts. Although we find that women who are sexually active eat less meat than those who are not, we do not find support for the core prediction regarding effect of cycle phase on meat consumption, nor do we find support for the ancillary prediction that meat consumption would be influenced by the presence or withdrawal of exogenous hormones. We replicate the finding that periovulatory total food intake is decreased compared to the rest of the cycle and find that sexually active women show a greater periovulatory decrease in food intake than sexually inactive women.

    Lesbian, gay men, and bisexual individuals (LGBs) often experience distress related to the recognition, self-acceptance, and disclosure of their sexual orientation. Retrospectively reported coping strategies enacted during sexual identity formation among LGBs were assessed in relation to current stress indices measured using environmental (frequency of perceived daily hassles), psychological (perceived distress), and biological (allostatic load [AL] levels representing physiological dysregulations) perspectives. Forty-six healthy LGBs between the ages of 18 and 45 (M = 23.91, SE = .80) participated. Questionnaires included the Ways of Coping Checklist adapted to disclosure milestones, Daily Hassles Inventory, and Perceived Stress Scale. AL was calculated using 21 biomarkers of neuroendocrine, immune, cardiovascular, and metabolic functioning. Avoidance coping during sexual identity formation was positively associated with frequency of daily hassles (β = .598, p < .001), perceived stress (β = .361, p = .015), and AL (β = .405, p = .006). By contrast, seeking social support was negatively associated with perceived stress (β = -.598, p = .048). Emotion-focused coping strategies during LGB sexual identity development are associated with current indices of biopsychosocial stress.

  14. Current Concepts for the IND-Directed Development of Microbicide Products to Prevent the Sexual Transmission of HIV.

    In the absence of an approved and effective vaccine, topical microbicides have become the strategy of choice to provide women with the ability to prevent the sexual transmission of HIV. Topical microbicides are chemical and physical agents specifically developed and formulated for use in either the vaginal or rectal environment to prevent the sexual transmission of infectious organisms. Although a microbicide product will have many of the same properties as other anti-infective therapeutic agents, the microbicide development pathway has significant differences which reflect the complex biological environment in which the products must act. These challenges to the development of an effective microbicide are reflected in the recently released FDA Guidance document which defines the microbicide development algorithm and includes the evaluation of preclinical efficacy and toxicity, and safety and toxicology, and indicates the necessity of testing of the active pharmaceutical product as well as an optimal formulation for delivery of the microbicide product. The microbicide development algorithm requires evaluation of the potential microbicidal agent and final formulated product in assays which mimic the microenvironment of the vagina and rectum during the sexual transmission of HIV, including the evaluation of activity and cytotoxicity in the appropriate biological matrices, toxicity testing against normal vaginal flora and at standard vaginal pH, testing in ectocervical and colorectal explant tissue, and irritation studies to vaginal, rectal and penile tissue. Herein, we discuss currently accepted practices required for the development of a successful microbicide product which will prevent virus transmission in the vaginal and rectal vaults.

    Hyperprolactinemia, particularly resulting from microprolactinoma, is known to induce erectile dysfunction. Contemporary published data do not allow to ascertain which prolactin (PRL) levels result in this type of sexual dysfunctions. The aim of this study was to evaluate the relationship between the extent of hyperprolactinemia and erectile dysfunction in 9 men with microprolactinoma and 8 patients with hyperprolactinemia as side-effects of sulpiride therapy. In all hyperprolactinemic males plasma PRL, LH, FSH and total testosterone levels were measured. The results showed that all patients with iatrogenic hyperprolactinemia were characterised by satisfactory sexual activity, although in 3 men hypotestosteronemia was revealed and in one patient gynecomastia was found. A range of PRL levels was 35-108 ng/ml. Among men with microprolactinoma the capability to lead a satisfactory sexual activity existed, even though in one patient PRL level was 2177 ng/ml, but in 3 other patients importance was observed when PRL concentrations were 281, 195 and 328 ng/ml. After bromocriptine therapy, when PRL levels diminished until 189, 78.3 and 110 ng/ml, the erectile dysfunction disappeared. Authors presume that sexual dysfunctions are not strictly connected with hyperprolactinemia and/or hypotestosterionemia, but probably are conditioned by other unexplicit factors (for example: a heterogeneous structure of PRL complexes).

    The ancient Greek physicians have not failed in their studies to indicate the beneficial role of sexual activity in human health. They acknowledged that sex helps to maintain mental balance. Very interesting is their observation that sex may help mental patients to recover. Nevertheless they stressed emphatically that sex is beneficial only when there is a measure in it, so they believed that sexual abstinence or excessive sexual activity affect negatively the mental and physical health of man. Ancient Greek physicians reached this conclusion by empirical observation. They tried to justify the mental imbalance, as the potential physical problems, which probably will be listed today in the psychosomatic manifestations, of people with long-term sexual abstinence or hyperactivity, based on the theory of humors which was the main methodological tool of ancient Greek medicine. Their fundamental idea was that the four humors of the body (blood, phlegm, yellow and black bile) should be in balance. Therefore they believed that the loss and the exchange of bodily fluids during sex help body's humors to maintain their equilibrium which in turn will form the basis for the physical and mental health. Although in ancient medical texts the irrationality presented by people in the aforementioned conditions was not attributed in any of the major mental illnesses recognized in antiquity, as mania, melancholy and phrenitis, our belief is that their behavior is more suited to the characteristics of melancholy, while according to modern medicine it should be classified in the depressive disorders. We have come to this conclusion, because common characteristics of people who either did not have sexual life or was overactive, was sadness, lack of interest and hope, as well as paranoid thinking that can reach up to suicide. Regarding the psychosomatic problems, which could occur in these people, they were determined by the ancient Greek physicians in the following; continuous headaches

    Comprehensive management of sexually transmitted infections (STIs) using vaginal or rectal microbicide-based intervention is one of the strategies for prevention of HIV infection. Herbal products have been used for treating STIs traditionally. Herein, we present in vitro activity of 10 plant extracts and their 34 fractions against three sexually transmitted/reproductive tract pathogens - Neisseria gonorrhoeae, Haemophilus ducreyi and Candida albicans. The plant parts were selected; the extracts/fractions were prepared and screened by disc diffusion method. The minimum inhibitory and minimum cidal concentrations were determined. The qualitative phytochemical analysis of selected extracts/fractions showing activity was performed. Of the extracts/fractions tested, three inhibited C. albicans, ten inhibited N. gonorrhoeae and five inhibited H. ducreyi growth. Our study demonstrated that Terminalia paniculata Roth. extracts/fractions inhibited growth of all three organisms. The ethyl acetate fraction of Syzygium cumini Linn. and Bridelia retusa (L.) Spreng. extracts was found to inhibit N. gonorrhoeae at lowest concentrations.

    Full Text Available Background: Low contraceptive use amongst unmarried sexually active young men and women presents an ethical dilemma in Indonesia, particularly in realising reproductive rights as a fundamental human right. This study aims to address the difficulties in extending access to family planning for unmarried sexually active youths. Methods: A review of the laws relating to the provision of family planning was combined with a secondary data analysis of the 2012 Indonesian Demographic Health Survey throughout 6 provinces on the island of Java. The sample population included 5,150 unmarried adolescents, aged 15 to 24 years. The 2012 Indonesian Demographic Health Survey was the first and only survey that included unmarried young women in Indonesia. The association between subjects who had 'ever had sex' and three groups of predictors (demographic characteristics, peer influences, and knowledge of contraceptive methods were examined using multivariate logistic regressions. Results:Results of the study found that subjects who were unmarried but had engaged in sexual activity were more likely to be those aged 19 to 21 years (OR = 2.36 and 22 to 24 years (OR = 6.81, of low education status (OR = 2.1, with a boyfriend or girlfriend (OR = 2.38, and those who approved of pre-marital sex (OR = 8.5. Conclusions: Results from this research suggest that new interpretations of the Law 52/2009 regarding family planning and Law 36/2009 that prohibits health services to unmarried sexually active youths are required in order to address the issues faced by Indonesia's youth

    Negative attitudes toward bisexuals have been documented among heterosexuals as well as lesbians/gay men, and a common theme is that bisexuals would not be suitable romantic or sexual partners. While gender, sexual orientation, and attitudes toward bisexuality influence people's willingness to engage in romantic or sexual activities with a bisexual partner, there are other individual differences that may contribute. The current study examined the associations between four types of conservative beliefs and willingness to engage in romantic/sexual activities with a bisexual partner in a sample of heterosexuals and lesbians/gay men (N = 438). Attitudes toward bisexuality were examined as a mediator of these associations. In general, results indicated that higher social dominance orientation, political conservatism, and essentialist beliefs about the discreteness of homosexuality were associated with lower willingness to engage in romantic/sexual activities with a bisexual partner. Further, more negative attitudes toward bisexuality mediated these associations. There were several meaningful differences in these associations between heterosexual women, heterosexual men, lesbian women, and gay men, suggesting that influences on people's willingness to be romantically or sexually involved with a bisexual partner may differ for different gender and sexual orientation groups. Implications for reducing stigma and discrimination against bisexual individuals are addressed.

    simple and computationally-efficient control strategies to actively select and use ocean currents so that a profiler can autonomously reach a desired destination. After briefly presenting a typical profiler and possible mechanical modifications for a coastal environment, we introduce simple mathematical...... models for the profiler and the currents it will use. We then present simple feedback controllers that, using the direction of the currents and taking into account the configuration of the environment (coastal or deep-sea), is able to steer the profiler to any desired horizontal location. To illustrate...... the approach, a few results are presented using both simulated currents and real current velocities from the North Sea....

    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.

    Among gay and bisexual men (GBM), a syndemic describes a situation in which negative conditions (e.g., childhood sexual abuse, intimate partner violence, depression, polysubstance use) co-occur such to amplify HIV risk. Research has suggested that sexual compulsivity (SC) may also be a syndemic condition. Between 2011 and 2013, 368 highly sexually active (9+ male partners in 90 days) GBM completed a survey of syndemic factors as well as measures of sexual compulsivity (Sexual Compulsivity Sca...

    2014-01-10

    Data from 1155 Czech women (493 using oral contraception, 662 non-users), obtained from the Czech National Survey of Sexual Behavior, were used to investigate evolutionary-based hypotheses concerning the predictive value of current oral contraceptive (OC) use on extra-pair and dyadic (in-pair) sexual behavior of coupled women. Specifically, the aim was to determine whether current OC use was associated with lower extra-pair and higher in-pair sexual interest and behavior, because OC use suppresses cyclical shifts in mating psychology that occur in normally cycling women. Zero-inflated Poisson (ZIP) regression and negative binomial models were used to test associations between OC use and these sexual measures, controlling for other relevant predictors (e.g., age, parity, in-pair sexual satisfaction, relationship length). The overall incidence of having had an extra-pair partner or one-night stand in the previous year was not related to current OC use (the majority of the sample had not). However, among the women who had engaged in extra-pair sexual behavior, OC users had fewer one-night stands than non-users, and tended to have fewer partners, than non-users. OC users also had more frequent dyadic intercourse than non-users, potentially indicating higher commitment to their current relationship. These results suggest that suppression of fertility through OC use may alter important aspects of female sexual behavior, with potential implications for relationship functioning and stability.

    OBJECTIVE: The aim of this study was to investigate whether bipolar pacemaker current lead can activate blood platelets. The null hypothesis was that 1 minute of electrical stimulation of platelets would not influence their subsequent reactivity to adenosine diphosphate (ADP). BACKGROUND: Both...... platelets and muscle cells contain actin and myosin filaments, and both cells are activated following calcium influx. Muscle cells open their calcium channels and contract when exposed to an electric current. Current through a bipolar pacemaker lead will expose a small volume of blood, including platelets...

  12. Sexual activity and cardiac risk: is depression a contributing factor?

    Roose, S P; Seidman, S N

    2000-07-20

    There is a well-documented association between depression, ischemic heart disease, and cardiovascular mortality. This association has a number of dimensions including: (1) depressed patients have a higher than expected rate of sudden cardiovascular death; (2) over the course of a lifetime, patients with depression develop symptomatic and fatal ischemic heart disease at a higher rate compared with a nondepressed group; and (3) depression after myocardial infarction (MI) is associated with increased cardiac mortality. Depression is also associated with sexual dysfunction, particularly erectile dysfunction. If depression is the primary illness, then erectile dysfunction can be considered a symptom of the depressive illness. However, if the erectile dysfunction is primary, men may develop a depressive syndrome in reaction to the loss of sexual function. Regardless of whether erectile dysfunction is a symptom of depression or depression is a consequence of erectile dysfunction, these conditions are frequently comorbid. Thus, the patient with ischemic heart disease who is depressed is more likely to have erectile difficulties. An attempt by this patient to engage in sexual activity is therefore more likely to be unsuccessful and, given the increase in cardiac mortality associated with depression, it may result in a serious cardiac event.

  13. Sexual attitudes and activities in women with borderline personality disorder involved in romantic relationships.

    Bouchard, Sébastien; Godbout, Natacha; Sabourin, Stéphane

    2009-01-01

    Women with Borderline Personality Disorder (BPD) are prone to have sexual relationship difficulties and dysfunctional attitudes toward sexuality. A sample of 34 heterosexual couples composed of women meeting BPD criteria was compared to a sample of dating or married women from the general population. A short form of the Sexual Activities and Attitudes Questionnaire (SAAQ) was used to measure six types of sexual attitudes. Women diagnosed with BPD did not differ from controls on the frequency of three types of sexual activities in the last year but their subjective sexual experiences differed: they showed stronger negative attitudes, felt sexually pressured by their partners, and expressed ambivalence toward sexuality. Regression analyses suggest that anxious attachment mediates the association between BPD and feeling pressured to engage in sex.

    Sexual activity accompanied by substance use can impair youth decision-making and enhance risk-taking behaviors. Less is known, however, about the sexual values, perceptions and subsequent sexual practices of youth whose sexual debut occurs while using alcohol/drugs. A cross-sectional anonymous online survey was conducted in April-August 2012 among undergraduate and graduate university students (aged 18 to 30) attending the 4th largest private university in Beirut. Pearson's Chi-square and regression models were run using Stata/IC 10.0. 940 university students had engaged in oral, anal and/or vaginal sex, of whom 10% admitted to having had consumed alcohol or taken drugs at sexual debut, a behavior that was more common in the males, less religious, non-Arabs, students living alone or who had lived abroad. Students who used alcohol/drugs at sexual debut were twice as likely to have: their first oral and vaginal sex with an unfamiliar partner [odds ratio (OR) = 2.6, 95% confidence interval (CI): (1.6, 4.2) and OR = 2.1 (1.2, 3.5), respectively], controlling for sex, nationality, current relationship status, living abroad after the age of 12, and spirituality. Students who had sex the first time while using alcohol/drugs were three times as likely to report having had 11 or more subsequent sexual partners versus one or two [OR = 3.0 (1.5-6.0)]; and almost twice as likely to ever engage in something sexual they did not want to do [OR = 1.7 (1.1, 2.8)]. Perceived peer pressure to have sex by a certain age [OR = 1.8 (1.1, 2.9)], and perceived peer norms to consume alcohol/drugs before sex [OR = 4.8 (2.3, 9.9)] were also strong correlates of having sex for the first time while using alcohol and/or drugs. Findings stress the importance of sexuality education for youth, and the need to begin understanding the true interplay--beyond association--between youth sexual practices and substance use behaviors from a broader public health perspective.

    2013-11-01

    Our objectives were to: (1) compare multiple measures of partnership concurrency, including the UNAIDS-recommended definition and (2) describe the prevalence and correlates of concurrent sexual partnerships among young Kenyan men. We analyzed 10,907 lifetime partnerships of 1,368 men ages 18-24 years enrolled in a randomized trial of male circumcision to reduce HIV-1 incidence in Kisumu. Partnership concurrency was determined by overlapping dates and examined over varying recall periods and assumptions. The lifetime prevalence of concurrency was 77 %. Sixty-one percent of all partnerships were concurrent and factors associated with concurrency differed by partner type. Point prevalence of concurrency at the time of the interview was consistently the highest and UNAIDS-recommended definition was the most conservative (25 vs. 18 % at baseline, respectively). Estimates of concurrency were influenced by methods for definition and measurement. Regardless of definition, concurrent partnerships are frequent in this population of young, sexually active men in high HIV prevalence Kisumu, Kenya.

    Full Text Available Abstract Background Military conscripts may experience a change in their attitude towards sex at times when sexual urges are at their peak during their physical growth. This study examines the experience, understanding, knowledge and attitudes regarding sexual activity of the military conscripts. Methods Data was obtained from a cross-sectional survey of 1127 young adult military conscripts, and were evaluated in Southern Taiwan from January to July 2009, their demographic data, sexual knowledge, attitudes and activities were assessed. Results Nearly 43% of the participants had performed penetrative vaginal intercourse at least once; 34% of the participants performed heterosexual oral sex at least once; almost 7% of participants had had homosexual intercourse, and 7.5% of participants had experienced homosexual oral sex in the past year. The mean sexual knowledge score based on 30 questions was 23.2 ± 4.0. The higher the educational level of the participants, the greater sexual knowledge they had obtained. Conclusion This study found that 43% of unmarried young recruits had experienced premarital sexual activity. However, their sexual knowledge was insufficient and should be strengthened by sex education from an earlier age. College aged and adult learners also have sex education needs, especially with regard to integrating sexuality and life, being able to relate responsibly as sexual beings to others, the use of contraception, and about sexually transmitted disease.

    Promoting effective decision-making in adolescents who are active sexually and those who are not incorporates knowledge of the changes occurring in the intellectual, psychological, and emotional realms. The health professional must provide comprehensive and effective counseling in a variety of creative ways during the adolescent period. The time to begin is with the young adolescent, 10 or 11 years old, and continue over time. The key to success is prevention: prevention of sex without full consent, unwanted pregnancy, ignorance of one's own body, and decisions by default.

    We assessed sexual behaviors before and 12-months after ART initiation among 277 Mozambicans attending an HIV clinic. Measured behaviors included the number of sexual partners, condom use, concurrent relationships, disclosure of HIV status, alcohol use, and partners' serostatus. Compared to before ART initiation, increases were seen 12 months after ART in the proportion of participants who were sexually active (48% vs. 64% respondents, P initiation. Although reported correct and consist condom use increased, the number of unprotected sexual relationships remained the same (n = 45). Non-disclosure of HIV-serostatus to sexual partners was the only significant predictor of practicing unprotected sex with partners of HIV-negative or unknown serostatus. Sexual activity among HIV-positive persons on ART increased 12 months after ART initiation. Ongoing secondary transmission prevention programs addressing sexual activity with multiple partners, disclosure to partners and consistent condom use with serodisconcordant partners must be incorporated throughout HIV care programs.

    Few studies have examined the associations of sexual activity with romantic cognitions, particularly longitudinally. We used a multi-analytic approach to examine the longitudinal, between-person, and within-person associations between sexual activity and romantic cognitions. We distinguished among sexual activity with four different types of partners-romantic partners, friends, acquaintances, and friends with benefits. An ethnically/racially representative sample of 185 participants (94 males & 91 females) completed questionnaires when they were 2.5, 4, and 5.5 years out of high school. Frequent sexual activity with a romantic partner was associated with positive romantic cognitions, including less avoidant and anxious relational styles, greater romantic life satisfaction, and romantic appeal. Frequent sexual activity with various nonromantic partners was often associated with more negative romantic cognitions, including avoidant styles, lower romantic life satisfaction, and lower romantic appeal. Few longitudinal effects were found. Findings contribute to a developmental task theory concepualization of sexual behavior.

  1. Effect of photoperiod on sexual activity of boar

    Full Text Available The main objective of this study was to assess the effect of photoperiod on sexual activity of three breeds of boars: Swedish Landrace (n=34, Large White (n=38, and Duroc (n=32. Boar sexual activity was analysed based on the libido index and intensity of ejaculation. The libido index was calculated as the ratio between the duration of ejaculation and time of preparation until ejaculation. The intensity of ejaculation was the volume of ejaculate (mL secreted in the unit of time (min. The effect of photoperiod was analysed as the effect of duration of daylight (12 h within photoperiod intervals (increasing and decreasing. Impact assessment was carried out by applying the General Linear Model procedure. Libido and intensity of ejaculation varied under the impact of photoperiod and the breed of boars. With the increase in age, the boar libido weakened, while the volume of ejaculate and intensity of ejaculation increased. Boars manifested better libido when the daylight lasted longer than 12 h in both photoperiod intervals. Different from libido, the volume of ejaculate and intensity of ejaculation were highest when the daylight was shorter than 12 h, but only in the decreasing photoperiod interval. Swedish Landrace boars manifested best libido, while in the production of sperm the Duroc boars were inferior compared with Swedish Landrace and Large White. The phenotypic relationship among libido, ejaculate volume, and ejaculation intensity ranges from very low to high; however, the coefficients were positive, which indicates the possibility of simultaneous improvement of these traits.

    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.

    2016-02-01

    Emerging research supports the notion that sexual compulsivity (SC) and hypersexual disorder (HD) among gay and bisexual men (GBM) might be conceptualized as comprising three groups-Neither SC nor HD; SC only, and Both SC and HD-that capture distinct levels of severity across the SC/HD continuum. We examined data from 370 highly sexually active GBM to assess how the three groups compare across a range of risk factors for HIV infection. Comparisons focused on psychosexual measures-temptation for condomless anal sex (CAS), self-efficacy for avoiding CAS, sexual excitation and inhibition-as well as reports of actual sexual behavior. Nearly half (48.9 %) of this highly sexually active sample was classified as Neither SC nor HD, 30 % as SC Only, and 21.1 % as Both SC and HD. While we found no significant differences between the three groups on reported number of male partners, anal sex acts, or anal sex acts with serodiscordant partners, the Both SC and HD group reported higher numbers of CAS acts and CAS acts with serodiscordant partners and also had a higher proportion of their anal sex acts without condoms compared to the SC Only group. Our findings support the validity of a three-group classification system of SC/HD severity in differentiating psychosexual and HIV-related sexual risk behavior outcomes in a sample of GBM who report similarly high levels of sexual activity. Notwithstanding the need for sex positive HIV prevention programs, interventions that attempt to help Both SC and HD men deal with distress and address their psychosexual needs specifically may derive HIV prevention benefits.

    Full Text Available Adolescent sexual risk behavior can lead to serious health consequences, yet few investigations have addressed its neurodevelopmental mechanisms. Social neurocircuitry is postulated to underlie the development of risky sexual behavior, and response to social reward may be especially relevant. Typically developing adolescents (N = 47; 18M, 29F; 16.3 ± 1.4 years; 42.5% sexual intercourse experience completed a social reward fMRI task and reported their sexual risk behaviors (e.g., lifetime sexual partners on the Youth Risk Behavior Survey (YRBS. Neural response and functional connectivity to social reward were compared for adolescents with higher- and lower-risk sexual behavior. Adolescents with higher-risk sexual behaviors demonstrated increased activation in the right precuneus and the right temporoparietal junction during receipt of social reward. Adolescents with higher-risk sexual behaviors also demonstrated greater functional connectivity between the precuneus and the temporoparietal junction bilaterally, dorsal medial prefrontal cortex, and left anterior insula/ventrolateral prefrontal cortex. The greater activation and functional connectivity in self-referential, social reward, and affective processing regions among higher sexual risk adolescents underscores the importance of social influence underlying sexual risk behaviors. Furthermore, results suggest an orientation towards and sensitivity to social rewards among youth engaging in higher-risk sexual behavior, perhaps as a consequence of or vulnerability to such behavior.

    The present study examined whether positive or negative links occur between psychosocial adjustment and sexual activity with four types of partners-romantic partners, friends, acquaintances, and friends with benefits. We examined longitudinal associations and concurrent between-person and within-person associations. A representative sample of 185 participants (93 males, 92 females), their friends, and mothers completed questionnaires when the participants were 2.5, 4, and 5.5 years out of high school. Regardless of the type of partner, more frequent sexual activity relative to the sexual activity of other young adults was associated with more substance use and risky sexual behavior (i.e., between-person effects). Similarly, for all types of nonromantic partners, more frequrent sexual activity relative to one's own typical sexual activity was associated with more substance use and risky sexual behavior (i.e., within-person effects). Differences in frequency of sexual activity with friends and acquaintances were associated with greater internalizing and externalizing symptoms as well as lower self-esteem. Follow-up analyses revealed the associations were particularly strong for friends with benefits. Women's sexual activity frequency with a nonromantic partner was more commonly associated with poorer psychosocial adjustment than such activity by men. More frequent sexual activity with a romantic partner was associated with higher self-esteem and lower internalizing symptoms. Few long-term effects were found for any type of sexual activity. The findings underscore the importance of examining relationship context and illustrate the value of using multiple analytic strategies for identifying the precise nature of associations.

Of 1981 sexually active male students, 1908 (96.3% completed the item for timing of the initiation of sexual activity and were included in bivariate trend analyses and multiple logistic regression analyses to compare the association between this timing and sexual behavior and risks. Results Male early sexual initiators had a significantly higher risk profile, including a significantly higher proportion reporting non-regular partners (i.e., casual or commercial partners, multiple partners, diagnosis with a sexually transmitted disease (STD, partner history of pregnancy, partner history of induced abortion, and less condom and oral contraceptive use, compared with late initiators. Multivariate analyses confirmed the increased likelihood of these risks in early initiators versus late initiators, other than partner type during the last year. Conclusion Our results showed that, compared to late initiators, people who initiated sexual activity early engaged in more risky behaviors that could lead to elevated risks of unwanted pregnancies and STDs or human immunodeficiency virus infection. Sex-education strategies should be focused on an earlier age, should include advice on delaying the age of first sexual activity, and should target young people who continue to take sexual risks.

    Men who have sex with men (MSM) are the group most at risk for HIV and represent the majority of new infections in the United States. Rates of childhood sexual abuse (CSA) among MSM have been estimated as high as 46%. CSA is associated with increased risk of HIV and greater likelihood of HIV sexual risk behavior. The purpose of this study was to identify the relationships between CSA complexity indicators and mental health, substance use, sexually transmitted infections (STIs) and HIV sexual risk among MSM. MSM with CSA histories (n = 162) who were screened for an HIV-prevention efficacy trial completed comprehensive psychosocial assessments. Five indicators of complex CSA experiences were created: CSA by family member, CSA with penetration, CSA with physical injury, CSA with intense fear, and first CSA in adolescence. Adjusted regression models were used to identify relationships between CSA complexity and outcomes. Participants reporting CSA by family member were at 2.6 odds of current alcohol use disorder (OR: 2.64: CI 1.24 – 5.63), 2 times higher odds of substance use disorder (OR 2.1: CI 1.02 – 2.36), and 2.7 times higher odds of reporting an STI in the past year (OR 2.7: CI 1.04 – 7.1). CSA with penetration was associated with increased likelihood of current PTSD (OR 3.17: CI 1.56 – 6.43), recent HIV sexual risk behavior (OR 2.7: CI 1.16 – 6.36) and a greater number of casual sexual partners (p = .02). Both CSA with Physical Injury (OR 4.05: CI 1.9 – 8.7) and CSA with Intense Fear (OR 5.16: CI 2.5 – 10.7) were related to increased odds for current PTSD. First CSA in adolescence was related to increased odds of major depressive disorder. These findings suggest that CSA, with one or more complexities, creates patterns of vulnerabilities for MSM, including PTSD, substance use, and sexual risk taking and suggests the need for detailed assessment of CSA and the development of integrated HIV prevention programs that address mental health and substance

  17. Sexual narcissism and infidelity in early marriage.

    2014-10-01

    There is theoretical reason to believe that narcissism is associated with infidelity. Yet, studies that have examined this association have yielded inconsistent results. Given that these inconsistencies may have emerged because prior studies used global assessments of narcissism that do not capture the extent to which the components of narcissism are activated in the sexual domain, the current research drew from two longitudinal studies of 123 married couples to examine the extent to which sexual narcissism predicted marital infidelity. Consistent with the idea that narcissism predicts sexual behavior when activated in the sexual domain, own sexual narcissism was positively associated with infidelity, controlling for own marital and sexual satisfaction, own globally-assessed narcissism, partner globally-assessed narcissism, and partner sexual narcissism. Helping to explain why this association emerged, further analyses demonstrated that it was driven by all four facets of sexual narcissism-sexual exploitation, grandiose sense of sexual skill, sexual entitlement (Study 1 only), and lack of sexual empathy (husbands only). Additionally, although partner sexual narcissism was unrelated to infidelity on average, partners' grandiose sense of sexual skill and partners' sexual entitlement (Study 2 only) were positively associated with infidelity, and partners' lack of sexual empathy was negatively associated with infidelity (Study 2 only). These findings highlight the benefits of using domain-specific measures of sexual narcissism in research on sexual behavior and the benefits of using domain-specific measures of personality more generally.

    Full Text Available To document knowledge and attitudes regarding sexuality and sexual practices of male adolescent high school students in Lima, Peru, a self-administered, anonymous survey was completed by 991 male adolescents aged 12-19 as part of a School-Based Sex Education Intervention model. Questions concerned sociodemographic information; family characteristics; personal activities; knowledge and attitudes regarding sexuality; sexual experience; and contraceptive use. Knowledge related to sexuality was limited. Males tended to mainly discuss sexuality with their male peers (49.8%. Attitudes towards sexual activity and condom use were largely positive, although some males expressed ambivalent feelings towards the latter. Of the sample, 43% had ever had sex; age at first sexual intercourse was 13 years. While 88% of the sample would use condoms, 74% also gave reasons for not using them. Sexual activity was related to age, ever having repeated a grade, living with only one parent or in a mixed family, activities such as going to parties, use of alcohol, tobacco, and drugs, and viewing pornographic videos or magazines. Many male adolescents were at risk of causing an unintended pregnancy or acquiring an STD.

    This study examined the role of stress as a mediator of the relationship between prior drug addiction and current high-risk sexual behaviour. Eight hundred twenty women aged 18 to 30 years, who received care at community-based family planning clinics, were interviewed using the Composite International Diagnostic Interview and the Sexual Risk Behavior Assessment Schedule. They also completed the brief version of the Self-Control Scale as a measure of problem-solving strategies and measures of recent stressful events, daily hassles and ongoing chronic stress. Regardless of addiction history, stress exposure during the previous 12 months was associated with risky sexual behaviour during the previous 12 months. Structural equation modelling revealed that 12-month stress levels mediated the relationship between past drug addiction and 12-month high-risk sexual behaviours, as well as the negative relationship between problem-solving strategies and high-risk sexual behaviours. Problem-solving strategies did not moderate the relationship between drug addiction and high-risk sexual behaviours. These findings suggest that stress management training may help reduce risky behaviour among young, low-income women. Copyright © 2014 John Wiley & Sons, Ltd.

    2014-06-01

    Changes in sexual function are a common outcome following risk-reducing salpingo-oophorectomy (RRSO), a prophylactic surgery for women at high risk of ovarian and other gynecologic cancers. Despite the known importance of sexuality in patients' quality of life and satisfaction with surgery, little is known about what predicts sexual activity following RRSO. The present study examined how mental and physical health variables predicted sexual activity before and after RRSO. We conducted a secondary analysis of quality of life measures collected in 85 women at high risk for ovarian cancer. Participants completed validated measures of mental, physical, and relationship health 1-2 weeks before surgery, and 2, 6 and 12 months following surgery. Across analyses, relationship satisfaction emerged as the most significant predictor of change in sexual activity: women with high relationship satisfaction were more likely to continue to have regular sexual activity following RRSO, even in the presence of vaginal menopausal symptoms. The effect of depression, anxiety and overall physical health on sexual activity was non-significant when controlling for relationship satisfaction. When counseling women about RRSO and its impact on sexual activity, clinicians should discuss the effect of the patient's relationship health on this outcome.

    Full Text Available Background The aim of the research was to present sexual functioning of pregnant women in terms of their assessment of the sexual life and marital relation. The study included 61 pregnant women (31 with high-risk pregnancy and 30 with a normal course of pregnancy, aged on average 28.5 years and pregnant on average for 27.5 weeks. Participants and procedure The study was based on the sociodemographic questionnaire The Female Sexual Function Questionnaire, SFQ28 (designed by Quirk et al., 2005, the Sexual Quality of Life Questionnaire – Female Version, SQoL-F (designed by Symonds et al., 2005, and the Dyadic Adjustment Scale, DAS (designed by Cieślak, 1989. Results The obtained results reveal changes in sexual functioning during pregnancy, mostly in terms of desire and excitement. The groups differed significantly in terms of sexual activity. Women with pathological pregnancy obtained lower results on the scales of desire, arousal, orgasm and satisfaction with sexual relationship. With every subsequent pregnancy week, both groups obtained lower results on the scales of arousal, orgasm and satisfaction with sexual activity. Neither pregnancy nor its length was related to the assessment of satisfaction with marital relation. Conclusions The conducted data analysis indicates that the subjective assessment of sexual life is related to the assessment of marital relation on the scale of emotional expression and relation coherence. No relation of sexual activity and sexual life with the assessment of the quality of marital relation was proved. However, the assessment of sexual life is related significantly to the assessment of the quality of marital relation.

    Alternating current (AC) is known to inactivate microbial growth in suspension, but how AC influences anaerobic biofilm activities has not been systematically investigated. Using a Geobacter dominated anaerobic biofilm growing on the electrodes of microbial electrochemical reactors, we found that high frequency AC ranging from 1 MHz to 1 kHz (amplitude of 5 V, 30 min) showed only temporary inhibition to the biofilm activity. However, lower frequency (100 Hz, 1.2 or 5 V) treatment led to 47 ± 19% permanent decrease in limiting current on the same biofilm, which is attributed to the action of electrohydrodynamic force that caused biofilm damage and loss of intercellular electron transfer network. Confocal microscopy images show such inactivation mainly occurred at the interface between the biofilm and the electrode. Reducing the frequency further to 1 Hz led to water electrolysis, which generated gas bubbles that flushed all attached cells out of the electrode. These findings provide new references on understanding and regulating biofilm growth, which has broader implications in biofouling control, anaerobic waste treatment, energy and product recovery, and general understanding of microbial ecology and physiology.

    Introdução: A crescente população de sobreviventes de cancro da mama tem redireccionado o interesse investigacional e prático para o impacto da doença e do seu tratamento nas várias áreas da qualidade de vida. A falta de questionários para avaliar de forma objectiva a disfunção sexual conduziu à necessidade de adaptar e validar culturalmente o Sexual Activity Questionnaire para utilização em Portugal. Material e Métodos: O Sexual Activity Questionnaire foi traduzido e retrovertido, sua versão de consenso refinada após teste de compreensão, e subsequentemente auto-administrado a uma amostra alargada de sobreviventes de cancro da mama em dois momentos, espaçados 15 dias, para julgar a sua validade e fiabilidade. Resultados: Após alterações minor à versão de consenso, o Sexual Activity Questionnaire foi aplicado a 134 doentes. Obteve-se uma estrutura de três factores (75,5% da variância), compreendendo as escalas do Prazer, Hábito e Desconforto, todas com boa consistência interna (α de Cronbach > 0,70), boa validade concorrente com o FACt-An e a checklist BCPT (r de Spearman > 0,65; p-value 0,44). Foi identificada inactividade sexual em 23,9% das mulheres, devido a falta de interesse ou ao facto de não ter parceiro. Discussão: Os dados reportados pelos doentes conduziram a alterações nos cuidados prestados, que passaram a contemplar a oncosexologia. Estudos futuros deverão focar-se na aplicabilidade deste questionário a amostras com diferentes características e mesmo à população global, para se poderem generalizar os resultados. Conclusão: A versão obtida do Sexual Activity Questionnaire é válida para avaliar a função sexual em sobreviventes de cancro da mama em Portugal.

    The purpose of this study was to compare male and female college students in four countries (Canada, Germany, Sweden, and the U.S.) on their lifetime experiences (prevalence) and frequency of recent experiences with six types of online sexual activities (OSA): sexual information, sexual entertainment, sexual contacts, sexual minority communities, sexual products, and sex work. Participants (N = 2690; M age, 24.65 years; 53.4 % women, 46.6 % men) were recruited from a university in each of the countries to complete an online survey that included background and demographic questions, and questions about OSA. Most participants reported experience with accessing sexual information (89.8 %) and sexual entertainment (76.5 %) online. Almost half (48.5 %) reported browsing for sexual products, and a substantial minority reported having engaged in cybersex (30.8 %). Very few participants (1.1 %) paid for online sexual services or received payment (0.5 %). In general, participants showed relatively infrequent experience with all types of OSA within the last 3 months. Men showed both higher prevalence and frequency of use of sexually stimulating material online than did women. However, this gender gap was smaller than in previous studies. Country and gender by country effects were (with one exception) either very small or non-existent, suggesting that, overall, students in the four countries were similar in their OSA experiences. Results are discussed in light of an emerging global net generation and globalized sexual culture.

    To identify the brain centers associated with visually evoked sexual arousal in the human brain, and to investigate the neural mechanism for sexual arousal using functional MRI (fMRI). A total of 20 sexually potent volunteers consisting of 10 males (mean age: 24) and 10 females (mean age: 23) underwent fMRI on a 1.5T MR scanner (GE Signa Horizon). The fMRI data were obtained from 7 slices (10 mm slice thickness) parallel to the AC-PC (anterior commissure and posterior commissure) line, giving a total of 511 MR images. The sexual stimulation consisted of a 1-minute rest with black screen, followed by a 4-minute stimulation by an erotic video film, and concluded with a 2-minute rest. The brain activation maps and their quantification were analyzed by the statistical parametric mapping (SPM 99) program. The brain activation regions associated with visual sexual arousal in the limbic system are the posterior cingulate gyrus, parahippocampal gyrus, hypothalamus, medial cingulate gyrus, thalamus, amygdala, anterior cingulate gyrus, insula, hippocampus, caudate nucleus, globus pallidus and putamen. Especially, the parahippocampal gyrus, cingulate gyrus, thalamus and hypothalamus were highly activated in comparison with other areas. The overall activities of the limbic lobe, diencephalon, and basal ganglia were 11.8%, 10.5%, and 3.4%, respectively. In the correlation test between brain activity and sexual arousal, the hypothalamus and thalamus showed positive correlation, but the other brain areas showed no correlation. The fMRI is useful to quantitatively evaluate the cerebral activation associated with visually evoked, sexual arousal in the human brain. This result may be helpful by providing clinically valuable information on sexual disorder in humans as well as by increasing the understanding of the neuroanatomical correlates of sexual arousal.

    The sexual transmitted pathogens associated with genital ulcers are Treponema pallidum, Haemophilus ducreyi, Calymmatobacterium granulomatis, Chlamydia trachomatis and Herpes simplex virus type 1 or 2. Although geographic differences still exist, herpetic infections prevalence is growing worldwide as the most frequent ulcerative sexual transmitted disease. The failure of the many different used guidelines in achieving a sustained reduction in the number of new cases, in particular the WHO syndromic management, leads into an over treatment of bacterial agents and missing of viral agents. This situation is also associated with poor efficacy and wasting of economical resources. Ulcerative and non-ulcerative sexual transmitted diseases are important in the world HIV pandemy because they promote HIV transmission and are also associated with the disease evolution. Portugal had until recently the highest incidence of HIV infection in Europe and that points out to importance of treating and control of both ulcerative and non-ulcerative sexual transmitted diseases in order.

These evidence-based guidelines provide advice on the management of STIs, including the use of the appropriate diagnostic methods and therapeutic regimens. Early and appropriate therapy has the potential to significantly reduce the long-term complications of STIs. The prevention of further infection through the counselling and treatment of partners contributes to the sexual health of patients.

    This study examined the masturbatory experiences and other sexual activities of young Korean males in military service. The actual status of masturbation and its relationship to sexual activity questionnaire. A total of 1,212 young males among military personnel in Korea were interviewed with sexuality questionnaires on masturbation, sexual intercourse and personal characteristics. We divided these subjects into four groups according to the age of initiation of masturbation and analyzed the relationship between masturbation and other sexual activities. The mean age of subjects was 22.03 +/- 1.22 (19-27) years. The percentage of men who reported ever having masturbated was 98.1% (1189/1212) and the average age of initiation of masturbation was 14.26 +/- 1.66 years. So we divided 1,212 males into four groups on the basis of the average age below and above one standard deviation. Overall, 67.7% (821/1212) had experienced sexual intercourse, and significantly, the earlier the initiation age of masturbation, the higher the coitus rate in each group (p masturbation were closely linked to the initiation age of masturbation, respectively (p masturbation was earlier. Coital incidence in this study was 67.7% for young males in Korean military service, and 21.5% of them had their first sexual intercourse with prostitutes. Prostitution still plays an important role in the sexual lives of males in Korea. The incidence of STD was over 10% and homosexual manifestation was seen in 1.07% of subjects. Thus a proper and sound sex education at school during childhood is needed in Korea. A large scale survey of sexual behavior in various populations is essential for the improvement of correct sexual concepts.

    Full Text Available The question of sexual activity prior to an event is a popular subject amongst athletes. No genuine answer to date has been established about the influence of sexual activity on athletic performance. The purpose of the present study was to review the literature regarding sexual activity effect on sporting performance from psychological perspective. The study was of non-empirical and descriptive one taking archival materials and first and second hand information into consideration. Due to cultural and ethical consideration, there was no empirical study found in Iran. Hence, we reviewed non-empirical and empirical studies carried out overseas. Overall, it was found there were scarcity and diversity of the opinions in the literature .So, the implications of the study will help sport psychologists, coaches, and academicians have a deep insight into sexual activity impact upon sporting performance. Finally, it is suggested academicians and practitioners seize the opportunity to study the subject which is still at an embryonic stage.

    Full Text Available This research studies the association of the cervical condyloma with the intraepithelial neoplasia, during sex activity, pregnancy, diagnose methods, cytology and colposcopy in teenagers. The objective of this research is to study the propaedeutics for the uterine coli condyloma diagnose in a group of teenagers. For this purpose, we have studied 131 teenagers sexually active with ages between 14 and 19 years and presenting histologically confirmed uterine coli condyloma. Association with intraepithelial neoplasia, sexual ativity duration, method of diagnose, pregnancy analysis, cytology and colposcopy results and association with vulva and vagina injuries were evaluated. The high association rate with condyloma and intraepithelial neoplasia after a short time of sexual activity and the none presence of macroscopic warts in the genital organs in 80% of cases presenting cervical condyloma, demonstrate that: a more careful investigation with colposcopy.and biopsy of the inferior genitals of the women-teenagers sexually active is needed, when presenting modified cervical cytology.

  7. 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.

    Typically, "non-romantic" sexual relationships are assumed to be casual; however, the emotional and social distinctions between romantic and non-romantic contexts are not well understood, particularly in adolescence. Data from the National Longitudinal Study of Adolescent Health (Add Health) was used to compare shared emotional (e.g., telling partner that they love her/him) and social (e.g., going out in a group) activities within romantic and non-romantic sexual relationships. Adolescents who reported exclusively romantic sexual relationships (n = 1,891) shared more emotional, but not social, activities with their partners than adolescents who were in non-romantic sexual relationships (n = 315; small effect size, r = .07-.13), akin to adolescents who experienced both relationship types (n = 519; small-to-medium effect size, r = .18-.38). Girls shared more emotional and social activities with their partners than boys when in romantic relationships (small effect size, r = .06-.10); there were no significant gender differences within non-romantic sexual relationships. Findings suggest that gendered scripts remain for sexual relationships that are romantic but not for those that are non-romantic. Notably, for the majority of adolescents, non-romantic relationships still held many emotional and social dimensions typical of romantic relationships and differences between relationship types were small. Although non-romantic relationships were less intimate than romantic sexual relationships, there was remarkable heterogeneity within this relationship type. Caution is advised when working with adolescents engaged in "casual" sexual relationships. Understanding the complexity of adolescent sexual relationships is critical for the advancement of effective sex education programming.

    Full Text Available Background: Pregnancy stimulates partners to search for ways to preserve their mutual emotionalrelations and satisfy their sexual needs, with some limitations. This study evaluates thefrequency and perception of sexual intercourse during pregnancy in a group of Iranian couples.Materials and Methods: In this cross-sectional study, 155 pregnant women were recruitedfrom two academic clinics in Tehran. The exclusion criteria were: any underlying disease,history of pelvic surgery or gynecologic and obstetric complications, abortion or sterility, andprevious preterm labor. A checklist was administrated in the labor room, that included: demographicdata, partus and their viewpoints about sexuality. Frequency of sexual activity in eachtrimester, vaginal intercourse, coitus position, orgasm, breast stimulation, condom usage, andpregnancy outcome were recorded. Data were analyzed with t- and chi-square tests.Results: Women and their husbands with sexual behaviors during pregnancy had a lowermean age; the majority were nulipara (p<0.05. The biggest reason for decreased intercoursein the first trimester was fear of abortion (39.45%. No significant relationshipbetween sexual activity in pregnancy and preterm labor, gestational age, membrane rupture,and fetal outcome was shown. There was a significant negative relationship betweenintercourse in the 2nd and 3rd trimesters and need to induction.Conclusion: Although our results showed that sexual intercourse had no adverse effecton the fetus and was a proper stimulus for the induction of delivery, its frequency wasreduced during the gestational stage due to parents’ fear of adverse effects.

    Multidimensional self-report measures of sexual function for women do not include the assessment of vulvar discomfort, limiting our understanding of its prevalence. In an effort to improve the measurement of patient-reported health, the National Institutes of Health funded the creation of the Patient Reported Outcomes Measurement Information System (PROMIS). This included the development of the PROMIS Sexual Function and Satisfaction measure, and version 2.0 of the Sexual Function and Satisfaction measure included 2 scales to measure vulvar discomfort with sexual activity. The objectives of the study were to describe the development of 2 self-reported measures of vulvar discomfort with sexual activity, describe the relationships between these scales and scales for lubrication and vaginal discomfort, and report the prevalence of vulvar discomfort with sexual activity in a large, nationally representative sample of US women. We followed PROMIS measure development standards, including qualitative development work with patients and clinicians and psychometric evaluation of candidate items based on item response theory, in a probability sample of 1686 English-speaking US adult women. We tested 16 candidate items on vulvar discomfort. We present descriptive statistics for these items, correlation coefficients among the vulvar and vaginal scales, and mean PROMIS scores with 95% confidence intervals separately by menopausal status for the 1046 women who reported sexual activity in the past 30 days. Based on the psychometric evaluation of the candidate items, we created 2 separate 4 item scales, one to measure labial discomfort and pain and one to measure clitoral discomfort and pain. Additional items not included in the scales assess pain quality, numbness, and bleeding. The correlations between the lubrication, vaginal discomfort, and the 2 vulvar discomfort measures ranged from 0.46 to 0.77, suggesting that these measures represent related yet distinct concepts.

    Full Text Available Autonomous Lagrangian profilers are now widely used as measurement and monitoring platforms, notably in observation programs as Argo. In a typical mode of operation, the profilers drift passively at their parking depthbefore making a vertical profile to go back to the surface. This paperpresents simple and computationally-efficient control strategies to activelyselect and use ocean currents so that a profiler can autonomously reach adesired destination. After briefly presenting a typical profiler andpossible mechanical modifications for a coastal environment, we introducesimple mathematical models for the profiler and the currents it will use. Wethen present simple feedback controllers that, using the direction of thecurrents and taking into account the configuration of the environment(coastal or deep-sea, is able to steer the profiler to any desiredhorizontal location. To illustrate the approach, a few results are presentedusing both simulated currents and real current velocity profiles from theNorth Sea.

    Contraceptive advice and supply (CAS) and sexually transmitted infection (STI) testing are increasingly provided in primary care. Most risk assessment tools are based on sexual risk behaviours and socio-demographics, for use online or in specialist services. Combining socio-demographic and psychosocial questions (e.g. religious belief and formative experience) may generate an acceptable tool for targeting women in primary care who would benefit from intervention. We aimed to identify psychosocial and socio-demographic factors associated with reporting key sexual risk behaviours among women in the British general population. We undertook complex survey analysis of data from 4911 hetero-sexually active women aged 16-44 years, who participated in Britain's third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), a national probability sample survey undertaken 2010-2012. We used multivariable regression to examine associations between the available psychosocial and socio-demographic variables in Natsal-3 and reports of three key sexual behaviours: a) 2+ partners in the last year (2PP); b) non-use of condoms with 2+ partners in the last year (2PPNC); c) non-use of condoms at first sex with most recent sexual partner (FSNC). We adjusted for key socio-demographic factors: age, ethnicity and socio-economic status (measured by housing tenure). Weekly binge drinking (6+ units on one occasion), and first sex before age 16 were each positively associated with all three sexual behaviours after adjustment. Current relationship status, reporting drug use (ever), younger age and living in rented accommodation were also associated with 2+ partners and 2 + partners without condoms after adjustment. Currently being a smoker, older age and respondent ethnicity were associated with FSNC after adjustment for all other variables. Current smoking status, treatment for depression (last year), and living at home with both parents until the age of 14 were each associated with

    Findings on women's sexuality across the menstrual cycle are inconsistent. One relatively consistent finding is a midcycle and premenstrual peak in sexual desire in freely cycling women. Results on the cycle-related effects on sexual behavior are less clear. Large proportions of reproductive-aged women use combined oral contraception (COC), but studies on potential cycle-related shifts in sexual desire and behavior are sparse. A prospective diary study assessed sexual desire, sexual behavior, and mood in 89 heterosexual couples. Women were using one of four contraceptive methods: (1) nonhormonal contraception, (2) low-dose COC containing 20 mcg ethinylestradiol and 75 mcg gestoden or desogestrel, (3) COC containing 35 mcg ethinylestradiol and 2 mg cyproteronacetate, and (4) COC containing 30 mcg ethinylestradiol and 3 mg drospirenone. No cycle effects of sexual desire were established in the COC group, but frequency of sexual intercourse declined in the last days of active pill taking. These results were similar in both female and male partners. Negative affect did not covary with sexual desire.

    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.

    The sexual health of transgender adolescents and young adults who present for health care in urban community health centers is understudied. A retrospective review of electronic health record (EHR) data was conducted from 180 transgender patients aged 12-29 years seen for one or more health-care visits between 2001 and 2010 at an urban community health center serving youth in Boston, MA. Analyses were restricted to 145 sexually active transgender youth (87.3% of the sample). Laboratory-confirmed HIV and sexually transmitted infections (STIs) seroprevalence, demographics, sexual risk behavior, and structural and psychosocial risk indicators were extracted from the EHR. Analyses were descriptively focused for HIV and STIs. Stratified multivariable logistic regression models were fit for male-to-female (MTF) and female-to-male (FTM) patients separately to examine factors associated with any unprotected anal and/or vaginal sex (UAVS). The mean age was 20.0 (SD=2.9); 21.7% people of color, 46.9% white (non-Hispanic), 21.4% race/ethnicity unknown; 43.4% MTF, and 56.6% FTM; and 68.3% were on cross-sex hormones. Prevalence of STIs: 4.8% HIV, 2.8% herpes simplex virus, 2.8% syphilis, 2.1% chlamydia, 2.1% gonorrhea, 2.8% hepatitis C, 1.4% human papilloma virus. Only gonorrhea prevalence significantly differed by gender identity (MTF 2.1% vs. 0.0% FTM; p=0.046). Nearly half (47.6%) of the sample engaged in UAVS (52.4% MTF, 43.9% FTM, p=0.311). FTM more frequently had a primary sex partner compared to MTF (48.8% vs. 25.4%; p=0.004); MTF more frequently had a casual sex partner than FTM (69.8% vs. 42.7% p=0.001). In multivariable models, MTF youth who were younger in age, white non-Hispanic, and reported a primary sex partner had increased odds of UAVS; whereas, FTM youth reporting a casual sex partner and current alcohol use had increased odds of UAVS (all psexual risk differ for MTF and FTM youth.

    Full Text Available Objectives: To study the effect of acute and repeated dose administration of lyophilized aqueous extract of the dried fruits of Tribulus terrestris (LAET on sexual function in sexually sluggish male albino rats. Materials and Methods: Aphrodisiac activity of the test drug was evaluated in terms of exhibited sexual behavior. In order to assess the effect of chronic T. terrestris exposure on the hypothalamus--pituitary--gonadal axis, testosterone level estimation and sperm count were carried out. Twenty-eight-day oral toxicity studies were carried out to evaluate the long-term effects of the LAET administration on different body systems. Results: A dose-dependent improvement in sexual behavior was observed with the LAET treatment as characterized by an increase in mount frequency, intromission frequency, and penile erection index, as well as a decrease in mount latency, intromission latency, and ejaculatory latency. The enhancement of sexual behavior was more prominent on chronic administration of LAET. Chronic administration of LAET produced a significant increase in serum testosterone levels with no significant effect on the sperm count. No overt body system dysfunctions were observed in 28-day oral toxicity study. Conclusions: Findings of the present study validate the traditional use of T. terrestris as a sexual enhancer in the management of sexual dysfunction in males.

    cabo proyectos de investigación en esta área y se desarrollen el marco legal y las guías específicas adaptadas a nuestro ámbito.Objectives: To undertake a critical literature review of published evidence on the effectiveness of contact tracing in sexually transmitted infections, mechanisms of referral, and the criteria for initiating this activity. To describe how these factors vary by causative agent and to characterize the current state of contact tracing in sexually transmitted infections in developed countries. Methods: A systematic literature review was undertaken using online databases and scientific publications, as well as guidelines and documents pertaining to the legal framework within which contact tracing takes place. Results: Contact tracing is specifically recommended for infections caused by Neisseria gonorrhoeae, Chlamydia trachomatis, syphilis and HIV. The principal approaches to contact tracing reported were patient referral, provider referral or conditional patient referral. In addition, patient-dispensed partner treatment and the use of new technologies were reported. Numerous studies have evaluated the efficacy, effectiveness and social and legal context of contact tracing in different countries and populations. This situation contrasts with that in Spain, where there is a notable absence of guidelines, legal framework and formal studies dealing with contact tracing in sexually transmitted infections. Conclusions: Contact tracing is an increasingly important tool in the public health management of sexually transmitted infections and should be valued as such. This activity should be an integral and effective component of the control and prevention of sexually transmitted infection programmes in all autonomous regions in Spain. Research in this field is required to develop the legal framework and practice guidelines appropriate to the local context.

  3. Sexual activity and contraceptive use: the components of the decisionmaking process.

    1998-06-01

    In light of the social consequences of early childbearing, unplanned pregnancy, and the transmission of AIDS, a great need exists to understand how adolescents make sexual and reproductive decisions. Drawing primarily on literature from sub-Saharan Africa, this article focuses on three behavioral outcomes: nonmarital sexual activity, contraceptive use, and condom use. It explores adolescent's perceptions of the costs and benefits of engaging in these behaviors, their assessment of their susceptibility to the potential consequences of their actions, and the role of family, peer, and dyadic factors in shaping their reproductive decisions. The literature reveals that cultural values regarding sexuality and gender roles, the power dimensions of adolescents' lives, and economic disadvantage exert powerful influences on the decisionmaking process. Decisions to engage in unprotected sex may also be based on insufficient knowledge and distorted judgements of the risks of becoming pregnant and acquiring sexually transmitted infections. Nondecisionmaking is found to be fairly common in some contexts.

    Full Text Available Abstract Background Sexually transmitted infections constitute the main health risk among adolescents. In developing countries the diagnosis and treatment of cervical infections is based on the syndromic approach. In this study we estimated the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae among female adolescents from a Health Sector of the city of Goiânia, Brazil, and validated cervicitis diagnosis using World Health Organization/Ministry of Health risk score and gynecological examination. Methods A cross-sectional community-based sample of 914 15- to 19-year-old female teenagers was randomly selected and referred to the local Family Health Program. Of these, 472 (51.6% were sexually active and gynecological examinations were carried out for 427. Endocervical samples were collected to perform the polymerase chain reaction for C. trachomatis and N. gonorrhoeae. Performance of risk score, the presence of mucopurulent discharge, friability, ectopia and pain during cervical maneuver were compared with the presence of C. trachomatis or N. gonorrhoeae or both. Results The prevalence of C. trachomatis and N. gonorrhoeae was 14.5% and 2.1%, respectively. The risk score had a specificity of 31.9% (95% confidence interval, 21.2 to 44.2 and a positive predictive value of 20.8% (95% confidence interval, 13.5 to 29.7. Friability was the component of the gynecological examination that presented the best performance with a sensitivity of 43.5%, specificity of 81.0%, and 30.6% of positive predictive value. Conclusion The prevalence of infection by C. trachomatis and N. gonorrhoeae was high among these sexually active adolescents. The syndromic approach is clearly inadequate for screening and treating these infections in this population. Therefore, the implantation of other strategies to control these infections among adolescents is urgently required.

    The objective of this cross-sectional study was to determine the factors associated with the attitudes toward premarital sexual activities among school-going adolescents in Kelantan, Malaysia. It was conducted among 1032 secondary school students using a self-administered validated questionnaire. Multiple logistic regression revealed that the risk factors for having permissive attitudes toward practice of premarital sexual activities were male students (odds ratio [OR] = 1.83; 95% confidence interval [CI] = 1.34-2.48), being less religious (OR = 2.02; 95% CI = 1.49-2.73), and younger age group of students (13 to 14 years old; OR = 1.42; 95% CI = 1.05-1.92). Having good knowledge on sexual and reproductive health was a protective factor against permissive sexual attitude (OR = 0.27; 95% CI = 0.20-0.36). In conclusion, male and young adolescents were at risk of having permissive attitudes toward sexual behaviors, but good knowledge on sexual and reproductive health and being more religious may protect them from it. © 2012 APJPH.

    The neurobiological bases of human sexual behavior are only partly understood. The etiology of most human sexual dysfunctions is not understood at all. Nevertheless, substantial progress has been made in the treatment of some male sexual disorders. The prime example should be erectile deficiency, where several efficient and safe treatments are available. Pharmacological treatment for premature ejaculation is also available, although it is still in an early stage. Disorders of sexual desire have attracted much attention when women are affected but far less so when men are concerned. Whereas animal models appropriate for testing treatments for problems with erection and premature ejaculation are available, it is questionable whether such models of the desire disorders have predictive validity. There seems to be many factors involved both in reduced and enhanced sexual desire, most of which are unknown. In this review we present some data suggesting that an electroencephalographic analysis of brain activity during exposure to sexually relevant stimuli in male rats and men and during execution of sexual behaviors in male rats may provide useful information. The effects of a commonly used drug, ethanol, on the electroencephalogram recorded during sexual events in rats and men are also described. Although this approach to the analysis of the central nervous activity associated with sexual desire, arousal and behavior is still in its infancy, the data obtained so far show a remarkable similarity between men and rats. This suggests that animal studies of electroencephalographic responses to drugs in sexual contexts may be useful for predicting effects in the human male. Copyright © 2014 Elsevier Inc.

    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 fre...

    This was a cross-sectional study to examine the different associations of age and sleep duration with sex steroid hormones and sexual activities in 531 Asian Chinese men aged between 29 and 72 years old. Sleep duration and sexual activities were evaluated through a self-administered questionnaire, and total testosterone (T), sex hormone-binding globulin (SHBG), estradiol (E2), and dehydroepiandrosterone sulfate (DHEAS) were measured by established immunoassay methods in a single blood sample collected between 8:00 and 11:00 am. Bioavailable T (BioT) was calculated using the Vermeulen formula. Age was a major determinant of sleep, sex steroid hormones, and sexual activities in men. BioT, DHEAS, coital frequency, masturbation, and sleep duration declined with age. On the other hand, SHBG and E2 increased with age. Sleep duration, independently of age, aerobic exercise, and body fat, was positively associated with T and BioT, but not with DHEAS, E2, or any of the sexual activities studied. Men who masturbated had higher levels of both T and BioT. DHEAS was significantly associated with coital frequency and desire for sex. The present study showed that besides age, sleep duration was associated with androgen concentrations in men, and thus the evaluation of sleep hygiene may be beneficial in the management of men with low androgen concentrations. DHEAS may be independently associated with some sexual functions in men.

    Full Text Available This study was aimed to determine whether the presence of sexually stimulated rams by photoperiodic and melatonin treatments can advance the resumption of post-partum sexual activity in Mediterranean ewes lambing in January and weaned at the end of the breeding season at 41°N, in March. Rams were exposed to two months of long days (16 h light/day and given three melatonin implants at the end of the long days (sexually-activated rams; SAR. Control rams (CR were exposed to the natural photoperiod. Thirty-six ewes weaned on 25 February were assigned to one of two groups. From 1 March to 30 June, one group was housed with four SAR males (SAR-treated; n = 18, and the other group (CR-treated; n = 18 was housed with four unstimulated rams. Ovulation was assessed once per week based on plasma progesterone concentrations. Estrus was monitored daily by marks left on ewes by rams’ harnesses. SAR-treated ewes had a shorter (p < 0.01 weaning–first estrus interval than CR-treated ewes (61 ± 17 days vs. 102 ± 47 days; mean date of first estrus after weaning on April 26 and June 6, respectively. The proportion of the ewes ovulating in April or May was higher (p < 0.05 in the SAR-treated group than in the CR-treated group. SAR-treated ewes resumed estrous activity sooner than CR-treated ewes such that, in April, May, and June, the proportion of females that exhibited estrus was higher (p < 0.01 in the SAR-treated group (72%, 89%, and 100%, respectively than in the CR-treated group (17%, 44%, and 61%, respectively. In conclusion, the introduction at weaning of sexually activated rams advanced the resumption of estrous activity in ewes in spring. The practical implications of this work could be important in ewes adapted for intensive production and accelerated lambing systems.

    The influence of sexual attitudes on sexual activity and expression has been relatively understudied in older populations. In the current study, we sought to understand the role sexual attitudes have on sexual well-being among middle-aged and young-old adults. Using a diverse sample of participants over the age of 45 (N = 384), a path model was analyzed to determine whether sexual attitudes contributed to sexual well-being. The model was then compared by gender. Results indicated: a) only age-relative sexual attitudes significantly contributed to sexual well-being; and b) the model was equally robust for both men and women, even though women held slightly more positive age-relative sexual attitudes than men. Therefore, among middle-aged and young-old adults, sexual well-being may be reduced by harboring negative ageist sexual attitudes. Efforts should be made to reduce stigma surrounding continued sexual activity and expression among the aged.

    2014-01-01

    Objective To examine the relation between “sexting,” (sending and sharing sexual photos online via text messaging and in-person) with sexual risk behaviors and psychosocial challenge in adolescence. Methods Data were collected online between 2010 and 2011 with 3,715 randomly selected 13- to 18-year-old youth across the United States. Results Seven percent of youth reported sending or showing someone sexual pictures of themselves, where they were nude or nearly nude, online, via text messaging, or in-person, during the past year. Although females and older youth were more likely to share sexual photos than males and younger youth, the profile of psychosocial challenge and sexual behavior was similar for all youth. After adjusting for demographic characteristics, sharing sexual photos was associated with all types of sexual behaviors assessed (e.g., oral sex, vaginal sex) as well as some of the risky sexual behaviors examined—particularly having concurrent sexual partners and having more past-year sexual partners. Adolescents who shared sexual photos also were more likely to use substances and less likely to have high self-esteem than their demographically similar peers. Conclusions While the media has portrayed “sexting” as a problem caused by new technology, health professionals may be more effective by approaching it as an aspect of adolescent sexual development and exploration and, in some cases, risk-taking and psychosocial challenge.

    Allergic rhinitis (AR) has been found to impact the daily activities of allergic patients. This includes the effects on sleep and chronic fatigue. The effect of AR on sexual function has not been well studied. The purpose of this study was to assess the impact of AR on sexual function, sleep, and fatigue. The Rhinosinusitis Disability Index (RSDI) is a quality of life (QOL), validated outcomes tool that assesses how AR affects QOL. Specific questions address the adverse consequence on sexual function, sleep, and fatigue. Four subsets of patient with AR who completed the RSDI were evaluated for the specific questions as well as the physical, emotional, functional, and total scores. The scores were compared with a cohort of normal subjects, patients with a diffuse group of rhinologic disorders, and patients scheduled for septal surgery (non-AR patients). Patients with AR had significantly higher (worse) sexual and sleep RSDI scores than the non-AR patients and normal subjects. Although the AR subjects also had significantly higher fatigue RSDI scores than the normal subjects, there was no significant difference between the AR and non-AR patients' fatigue scores. Non-AR patients had significantly higher sexual, sleep, and fatigue RSDI scores than the normal subjects. AR has a significant negative impact on sexual function and can result in sleep disturbances and fatigue as measured by the RSDI.

  16. Transient sodium current at subthreshold voltages: activation by EPSP waveforms.

    2012-09-20

    Tetrodotoxin (TTX)-sensitive sodium channels carry large transient currents during action potentials and also "persistent" sodium current, a noninactivating TTX-sensitive current present at subthreshold voltages. We examined gating of subthreshold sodium current in dissociated cerebellar Purkinje neurons and hippocampal CA1 neurons, studied at 37°C with near-physiological ionic conditions. Unexpectedly, in both cell types small voltage steps at subthreshold voltages activated a substantial component of transient sodium current as well as persistent current. Subthreshold EPSP-like waveforms also activated a large component of transient sodium current, but IPSP-like waveforms engaged primarily persistent sodium current with only a small additional transient component. Activation of transient as well as persistent sodium current at subthreshold voltages produces amplification of EPSPs that is sensitive to the rate of depolarization and can help account for the dependence of spike threshold on depolarization rate, as previously observed in vivo.

    2010-01-01

    Background The behavior of adolescents puts them at an increased risk for HIV and other STIs, and their knowledge about HIV/AIDS is often inadequate. An understanding of how AIDS knowledge and sexual activity co-vary among Flemish secondary school students and of how education type, specifically, affects these students is limited. This study addresses the question of whether the effects of education type on HIV/AIDS knowledge and sexual activity are independent of the socio-demographic characteristics of the students. Methods Data from the Flemish Educational Assessment survey, which collected data from a large representative sample of third- and fifth-grade high school students (N = 11,872), were used. Data were analyzed using multilevel logistic and Poisson regression techniques. Results There is an indication that type of education affects both an adolescent's sexual activity and his/her AIDS knowledge; these effects prove robust for differences in socio-economic backgrounds. Students in lower status education types are more likely to be sexually active and to have poorer AIDS knowledge. The relationship between AIDS knowledge and sexual activity is, however, more complex. Although students in education types with poorer AIDS knowledge are more sexually active, within each of these groups the sexually active have better AIDS knowledge than the non-sexually active. There is also evidence of active information seeking by sexually active students, which leads to improved AIDS knowledge. Conclusion These findings are consistent with the literature on the role of the educational system in the reproduction of social inequalities. Students from lower status education types are at increased sexual risk compared to those from higher status types. There is also evidence of active information seeking by sexually active students, which leads to improved AIDS knowledge. PMID:20092623

    Full Text Available David Chang, Jon Kobashigawa Cedars-Sinai Heart Institute, Los Angeles, CA, USA Abstract: Heart transplant remains the most durable option for end-stage heart disease. Cardiac allograft immune activation and heart transplant rejection remain among the main complications limiting graft and recipient survival. Mediators of the immune system can cause different forms of rejection post-heart transplant. Types of heart transplant rejection include hyperacute rejection, cellular rejection, antibody-mediated rejection, and chronic rejection. In this review, we will summarize the innate and adaptive immune responses which influence the post-heart transplant recipient. Different forms of rejection and their clinical presentation, detection, and immune monitoring will be discussed. Treatment of heart transplant rejection will be examined. We will discuss potential treatment strategies for preventing rejection post-transplant in immunologically high-risk patients with antibody sensitization.

    Women with sexual problems (e.g., difficulties with desire, arousal, lubrication, orgasm, and pain during sexual activity) experience more depressive symptoms, and poorer sexual functioning and relationship satisfaction compared with unaffected women. A robust literature highlights the importance of sexual communication, and sexual self-disclosures in particular, for the well-being of individuals in romantic relationships. However, little is known about the disclosure of sexual problems to romantic partners and its association with women's psychological, sexual, and relationship well-being. This study examined the proportion of women (N = 277) who disclose (vs. do not disclose) sexual problems to their partner, and the consequences of disclosure. Women (Mage = 29.79, SD = 6.54) completed online validated measures assessing sexual problems, relationship satisfaction, sexual functioning, and depressive symptoms. The majority (69.3%) reported disclosing sexual problems to their current romantic partner. Disclosers reported fewer depressive symptoms, and greater sexual functioning and relationship satisfaction compared to nondisclosers. Disclosing sexual problems may benefit women's well-being by enhancing intimacy or allowing couples to adapt sexual activities to accommodate sexual problems. Clinicians might use cognitive-behavioral strategies to assist women in disclosing sexual problems to partners to maximize the potential psychological, sexual, and relationship benefits.

  2. Sexual Regret

    2016-12-01

    Full Text Available The current study sought to answer three key questions about explaining the emotion of regret in the domain of casual sex: Are sex differences in sexual regret robust or attenuated in a highly egalitarian culture? What proximate psychological variables might explain sex differences in sexual regret? And what accounts for within-sex variation in experiences of sexual regret about casual sex. We conducted a study of 263 Norwegian students (ages 19–37 who reported how much they regretted having either engaged in, or passed up, their most recent casual sexual experience. Sex differences in sexual regret are not attenuated in this sexually egalitarian culture. The study revealed sex differences in worries about pregnancy, STIs, and reputation; however, these predictors did not succeed in accounting for the sex differences in regret engaging in casual sex. Sexual gratification and socio-sexual orientation both predicted the sex differences in casual sex regret. In contrast, only socio-sexual orientation attenuated the sex difference in regret passing up casual sex. Predictors of within-sex variation in casual sexual regret included worry about sexual reputation, experienced gratification during the encounter, and socio-sexual orientation. Discussion focuses on implications for the psychological design features of this relatively neglected emotion.

  3. Effects of SNS activation on SSRI-induced sexual side effects differ by SSRI.

    Ahrold, Tierney K; Meston, Cindy M

    2009-01-01

    Selective serotonin reuptake inhibitors (SSRIs) are associated with significant sexual side effects. By definition, all SSRIs increase overall serotonin (5HT) by binding to serotonin autoreceptors (5HT(IA)); however, each SSRI has a unique portfolio of secondary binding properties to other neurotransmitters such as norepinephrine (NE). As 5HT(IA) receptors mediate NE neurotransmission, SSRIs that are highly selective for 5HT(IA) are more likely to reduce NE efficiency; however, in SSRIs that are less selective for 5HT(IA), this could be counteracted by secondary binding to NE. Norepinephrine is the major neurotransmitter of the sympathetic nervous system (SNS), which has been shown to mediate genital arousal in women; thus, it is possible that increasing SNS activity in women taking SSRIs that are highly selective for 5HT(IA) may counteract sexual side effects in those women. To test this hypothesis, we conducted a reanalysis of Meston (2004)'s 8-week, double-blind, cross-over, placebo-controlled study of the effects of ephedrine (50 mg taken 1 h prior to sexual activity) on self-reported sexual functioning of women taking paroxetine (N = 5), sertraline (N = 7), or fluoxetine (N = 7). As predicted, women taking SSRIs, which are highly selective for 5HT(IA) (sertraline, paroxetine), showed improvement in sexual arousal and orgasm. By contrast, women taking SSRIs, which are less selective for 5HT(IA) relative to NE (fluoxetine), showed no change or decrease in sexual functioning. These findings have implications for treating certain SSRI-induced sexual side effects.

    This paper examines connectedness to, communication with and monitoring of unmarried adolescents in Ghana by parents, other adults, friends and key social institutions and the roles these groups play with respect to adolescent sexual activity. The paper draws on 2004 nationally-representative survey data and qualitative evidence from focus group discussions and in-depth interviews with adolescents in 2003. Adolescents show high levels of connectedness to family, adults, friends, school and religious groups. High levels of adult monitoring are also observed, but communication with family about sex-related matters was not as high as with non-family members. The qualitative data highlight gender differences in communication. Multivariate analysis of survey data shows a strong negative relationship between parental monitoring and recent sexual activity for males and females, and limited effects of communication. Creating a supportive environment and showing interest in the welfare of adolescents appear to promote positive sexual and reproductive health outcomes.

    To investigate factors associated with favorable pregnancy attitudes among teenage girls. Participants were sexually active teenage girls aged 15-18 years old (n = 965) who took part in the 2002 or 2006-2010 National Survey of Family Growth (NSFG). Multinomial multivariable logistic regression was used to assess the likelihood of being pleased with a teenage pregnancy. Sixteen percent of sexually active teenage girls (n = 164) would be pleased (11 % a little pleased, 5 % very pleased) if they became pregnant. In a multivariable model, participants who had not yet discussed sexual health topics (i.e., how to say no to sexual intercourse or birth control) or had only discussed birth control with a parent were more likely to be very pleased with a teenage pregnancy than participants who had discussed both topics with a parent. Prior pregnancy, racial/ethnic group status, older age, and having parents with a high school education or less also increased the odds of being pleased with a teenage pregnancy. Being pleased with a teenage pregnancy was correlated with a lack of discussion of sexual health topics with parents, prior pregnancy, and sociodemographic factors (having less educated parents, racial/ethnic group status). Pregnancy prevention efforts can be improved by acknowledging the structural and cultural factors that shape teenage pregnancy attitudes.

    There has been a long-standing debate on the question of whether or not electric currents in solar active regions are neutralized. That is, whether or not the main (or direct) coronal currents connecting the active region polarities are surrounded by shielding (or return) currents of equal total value and opposite direction. Both theory and observations are not yet fully conclusive regarding this question, and numerical simulations have, surprisingly, barely been used to address it. Here we quantify the evolution of electric currents during the formation of a bipolar active region by considering a three-dimensional magnetohydrodynamic simulation of the emergence of a sub-photospheric, current-neutralized magnetic flux rope into the solar atmosphere. We find that a strong deviation from current neutralization develops simultaneously with the onset of significant flux emergence into the corona, accompanied by the development of substantial magnetic shear along the active region's polarity inversion line. After the region has formed and flux emergence has ceased, the strong magnetic fields in the region's center are connected solely by direct currents, and the total direct current is several times larger than the total return current. These results suggest that active regions, the main sources of coronal mass ejections and flares, are born with substantial net currents, in agreement with recent observations. Furthermore, they support eruption models that employ pre-eruption magnetic fields containing such currents.

    Background: Menopause represents the end of women reproductive career and it is at this time they begin to manifest morbidities such as urinary incontinence. Aim: To document proximate determinants of sexual activity and urological morbidities of menopausal women. Subjects and Methods: This was a community survey conducted among 254 menopausal women Mokola in Ibadan, Nigeria in 2008. Respondents were selected using cluster sampling technique. Interviewer administered questionnaires were used to obtain information on their characteristics, pattern of urological and sexual activities. Descriptive, bivariate and multivariable tests were performed with Statistical Package for the Social Sciences 15.0 (Chicago, IL USA) and statistical significance was set at P value less than 0.05. Results: The mean age of subjects was 60.3 (standard deviation = 10.2 years). About 33.5% (85/254) was still sexually active. About 68% (173/254) reported a reduction in sexual frequency since menopause while 31.5% (80/254) reported no change. The mean self-rated sexual performance score was 4.3 based on a numerical scale where 10 is the maximum obtainable. Significant predictors of reduction in sexual activity were age at menopause and education. Those between 45 and 49 years were less likely than those at 55 years or more (odds ratio [OR] = 0.21; 95% confidence interval OR = 0.05-0.87) while women with at least secondary education were thrice less likely than those with none to report a reduction in sexual activity after menopause. Less than a tenth reported urinary incontinence as a complaint. Urge incontinence was the most commonly reported followed by dysuria and stress incontinence. Less than a quarter of them had requested for a form of treatment. Conclusion: Sexual performance of Nigerian menopausal women is associated with age at menopause and education. Non-fistulous urinary incontinence is now being mentioned as a complaint contrary to the widely held view that it is part of the

    The magnitude of sex differences in human brain and behavior and the respective contributions of biology versus socialization remain a topic of ongoing study in science. The preponderance of evidence attests to the notion that sexual differentiation processes are at least partially hormonally mediated, with high levels of prenatal androgens facilitating male-typed and inhibiting female-typed behaviors. In individuals with Disorders/Differences of Sex Development (DSD), hormonal profiles or sensitivities have been altered due to genetic influences, presumably affecting gender(ed) activity interests as well as gender identity development in a minority of the affected population. While continued postnatal androgen exposure in a number of DSD syndromes has been associated with higher rates of gender dysphoria and gender change, the role of a number of mediating and moderating factors, such as initial gender assignment, syndrome severity and clinical management remains largely unclear. Limited investigations of the associations between these identified influences and gendered development outcomes impede optimization of clinical care. Participants with DSD (n=123), recruited in the context of a Dutch multi-center follow-up audit, were divided in subgroups reflecting prenatal androgen exposure, genital appearance at birth and gender of rearing. Recalled childhood play and playmate preferences, gender identity and sexual orientation were measured with questionnaires and semi-structured interviews. Data were compared to those of control male (n=46) and female participants (n=79). The findings support that (a) prenatal androgen exposure has large effects on (gendered) activity interests, but to a much lesser extent on sexual orientation and that (b) initial gender of rearing remains a better predictor of gender identity contentedness than prenatal androgen exposure, beyond syndrome severity and medical treatment influences. Nonetheless, 3.3% of individuals with DSD in our

    A detailed sexual history is the cornerstone for all sexual problem assessments and sexual dysfunction diagnoses. Diagnostic evaluation is based on an in-depth sexual history, including sexual and gender identity and orientation, sexual activity and function, current level of sexual function, overall health and comorbidities, partner relationship and interpersonal factors, and the role of cultural and personal expectations and attitudes. To propose key steps in the diagnostic evaluation of sexual dysfunctions, with special focus on the use of symptom scales and questionnaires. Critical assessment of the current literature by the International Consultation on Sexual Medicine committee. A revised algorithm for the management of sexual dysfunctions, level of evidence, and recommendation for scales and questionnaires. The International Consultation on Sexual Medicine proposes an updated algorithm for diagnostic evaluation of sexual dysfunction in men and women, with specific recommendations for sexual history taking and diagnostic evaluation. Standardized scales, checklists, and validated questionnaires are additional adjuncts that should be used routinely in sexual problem evaluation. Scales developed for specific patient groups are included. Results of this evaluation are presented with recommendations for clinical and research uses. Defined principles, an algorithm and a range of scales may provide coherent and evidence based management for sexual dysfunctions. Copyright © 2016 International Society for Sexual Medicine.

    1992-01-01

    The Santiago Young Adult Reproductive Health Survey was conducted in 1988 to examine the sexual behavior of and contraceptive use among young adults in Chile. The survey was based on multistage household probability samples of 865 women and 800 men aged 15-24 who were living in Santiago in 1988. Findings show that 35 percent of females and 65 percent of males had had premarital intercourse. Among those who had done so, the median age at first experience was 18.4 years for women and 16.4 years for men. Only 20 percent of females and 19 percent of males used contraceptives at first premarital intercourse. Use of contraceptives increased with age at the time of that event. Fertility data reveal that 70 percent of first births were premaritally conceived, and more than one-third of these were born prior to union. The high rates of premarital and unintended pregnancy among young women and the low prevalence of effective contraceptive use indicate a need for greater emphasis on sex education and family planning services directed at adolescents and unmarried young adults in Santiago.

    2013-01-01

    Transactional sex, or the exchange of sex for material goods or money, is a risky sexual behavior that has been linked to HIV/AIDS and gender-based violence. Throughout sub-Saharan Africa, transactional sex remains a common practice, putting men and women at risk of HIV. However, little is known of how community environments shape men's participation in risky transactional sex. This analysis examines community-level influences on participation in risky transactional sex among sexually active men in three African countries (Malawi, Tanzania, and Nigeria). The analysis uses Demographic and Health Survey (DHS) data to examine the association between men's report of risky transactional sex and community characteristics including economic, gender norms, HIV behavior and knowledge, and demographic factors. The results show that men residing in communities with more female education and later age of first birth are less likely to report risky transactional sex, while men who live in communities where men report higher number of sexual partners are more likely to report risky transactional sex. While programmatic interventions should continue to improve women's status individually and relative to men, such efforts should be extended to recognize that many community and cultural influences also affect men's sexual behavior. Programs that understand, discuss, and challenge community factors that influence men's sexual behavior may be able to provide a more effective intervention resulting in opportunities for communities to initiate behavioral change.

    To assess sexual activity and contraceptive knowledge and practice by gender among university students. Descriptive and cross-sectional study conducted at Ege University, Turkey, with 1000 volunteering students. Data collection was stopped when 500 students of each gender had participated. Of the surveyed students, 50.3% (27.4% female, 73.2% male) reported having had sexual intercourse; the mean age at first sexual intercourse was 18.4 years for girls and 16.9 years for boys. We found that 44.5% of female and 30.6% of male students failed to use contraception at their first coitus, whereas 2.2% of female and 13.7% of male students failed to do so at their most recent intercourse. The rate of condom usage for students' first sexual encounter was 50.1% (35.8% female, 55.5% male) and was 67.8% (70.1% female, 66.9% male) at their most recent intercourse. Abortion was mentioned by 43.9% of female and 39.2% of male students as a method of preventing pregnancy after unprotected coitus. Male Turkish students had started sexual relations at a younger age but had less often unprotected first sex than female students.

    Full Text Available The success of global treatment as prevention (TasP efforts for individuals living with HIV/AIDS (PLWHA is dependent on successful implementation, and therefore the appropriate contribution of social and behavioral science to these efforts. Understanding the psychosocial context of condomless sex among PLWHA could shed light on effective points of intervention. HPTN 063 was an observational mixed-methods study of sexually active, in-care PLWHA in Thailand, Zambia, and Brazil as a foundation for integrating secondary HIV prevention into HIV treatment. From 2010-2012, 80 qualitative interviews were conducted with PLWHA receiving HIV care and reported recent sexual risk. Thirty men who have sex with women (MSW and 30 women who have sex with men (WSM participated in equal numbers across the sites. Thailand and Brazil also enrolled 20 biologically-born men who have sex with men (MSM. Part of the interview focused on the impact of HIV on sexual practices and relationships. Interviews were recorded, transcribed, translated into English and examined using qualitative descriptive analysis. The mean age was 25 (SD = 3.2. There were numerous similarities in experiences and attitudes between MSM, MSW and WSM across the three settings. Participants had a high degree of HIV transmission risk awareness and practiced some protective sexual behaviors such as reduced sexual activity, increased use of condoms, and external ejaculation. Themes related to risk behavior can be categorized according to struggles for intimacy and fears of isolation, including: fear of infecting a sex partner, guilt about sex, sexual communication difficulty, HIV-stigma, and worry about sexual partnerships. Emphasizing sexual health, intimacy and protective practices as components of nonjudgmental sex-positive secondary HIV prevention interventions is recommended. For in-care PLWHA, this approach has the potential to support TasP. The overlap of themes across groups and countries

    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

    2011-07-01

    The present study sought to evaluate the relative associations of exercise, sleep and other lifestyle habits with aging, sex hormones, percent body fat (%BF) and sexual activities in men living in the community. A better understanding of this complex interrelationship is important in helping the formulation of modalities for a holistic approach to the management of aging men. The results showed that age is a major determinant for many physiological parameters, including sleep, hormonal and metabolic parameters, some lifestyle factors and sexual activities. Testosterone (T), bioavailable testosterone (BioT) and dehydroepiandrosterone sulphate (DHEAS) concentrations decreased with age, while estradiol (E2), sex hormone-binding globulin (SHBG) and %BF increased with age. In addition, there exist intricate associations among hormonal and lifestyle factors, %BF and age. High-intensity exercise and longer duration of sleep were associated with higher concentrations of T and BioT. T was shown to be associated positively with men who were engaged in masturbation. DHEAS was associated with men wanting more sex and with good morning penile rigidity. Older Singaporean men tended to sleep for shorter duration, but exercised more intensely than younger men. Coital and masturbation frequencies decreased with age, and a significantly greater number of younger men were engaged in masturbation. Relationship between the partners is a key determinant of sexuality in men. It appears that T may have a limited, while dehydroepiandrosterone (DHEA) have a greater role than previously suggest, as a motivational signal for sexual function in men. Both biological and psychosocial factors interact with each other to influence sexual functions in men. Hence, a biopsychosocial approach may be more appropriate for a more lasting resolution to sexual dysfunctions in men.

    Full Text Available In a demographic sense, adolescents are a population group which is yet to take part in birth giving. Therefore, their sexual behavior and especially sexual activity at early ages which is not only unfavorable from the aspect of the individual, meaning risk for psycho-physical health, but from the aspect of society as well, as regards population fertility, deserves special attention. This paper shows the results of in-depth research carried out in Belgrade from September 2001 to October 2002 with an aim to establish which factors determine a young person, of sixteen years old or younger, to become sexually active. It was carried out on a sample of 111 adolescent girls between 14 and 20 years old which turned to the Republic Family Planning Center Youth Counseling Clinic of the Institute for Mother and Child Health Care of Serbia. The research showed that sexual experience, realized at an early age was an integral part of development and maturing for the largest number of surveyed girls. In the largest number of cases it was a positive experience, induced by love and experienced with a partner, mainly of the same age, with which they were in a longer, stable relationship. Nevertheless, it could be concluded from the results obtained by the research that the surveyed girls could have more easily and efficiently solved their problems and dilemmas regarding sexuality had they had the possibility to obtain a better insight into their personal feelings and feelings of others at the right time, as well as developed social experience and experience in mastering control of their impulses. With a certain number of surveyed girls that would have meant a delay in their sexual activities to a later age. This also refers to the prevention of other risky behavior such as use of alcohol and drugs, which also have an influence on changing sexual behavior, making it more risky. It is important to stress that the surveyed adolescent girls themselves recognized the

    2009-07-01

    National and international decisions on financing for sexual and reproductive health (SRH) services have profound effects on the type, unit costs and distribution of SRH commodities and services produced, and on their availability and consumption. Much international and national funding is politically driven and is doing little for equity and quality improvement. Financing remains a significant challenge in most developing countries and demands creative responses. While no "one-size-fits-all" solution exists, there are numerous ongoing examples of successful innovations, many of which are focusing on resource pooling and on purchasing or subsidising SRH services. In this article we have used interviews, grey literature and presentations made at a range of recent public fora to identify new and innovative ways of financing SRH services so as to increase equity in developing countries. Because SRH services are often of low value as a personal good but high value as a public good, we summarise the issues from a societal perspective, highlighting the importance of financing and policy decisions for SRH services. We provide a structured overview of what novel approaches to financing appear to have positive effects in a range of developing countries. Targeting, government payment mechanisms, subsidy delivery and co-financing for sustainability are highlighted as showing particular promise. Examples are used throughout the article to illustrate innovative strategies.

    2007-01-01

    Full Text Available Sexually transmitted infections (STIs are more dynamic than other infections prevailing in the community. It is important that such dynamic epidemiological changes in STIs are acknowledged and kept track of in a vast and populous developing country like India, particularly in this HIV era. It is with this aim that the authors have reviewed the relevant literature in STI epidemiology in India during the past 25 years. Admittedly, there has been heterogeneity of data to account for the subcontinental dimension of this country. But a basic pattern in the changing epidemiology is discernible. Like the developed countries, in India too the bacterial STIs like chancroid and gonorrhea are declining, while viral STIs like HPV and herpes genitalis are on an upswing. The overall decline in the prevalence of STIs has to be interpreted with caution, however. This may partially reflect the improved facilities of treatment in the peripheral centres that obviates the need of many patients in attending the STD clinics in the tertiary centres. Also, the improved pharmacotherapy of many of the bacterial STIs may result in partial clearance and non-reporting of many of these infections.

    Full Text Available Background Young people’s vulnerability to risky or unwanted sex and other unhealthy behaviours is tied to host of individual, family, and community factors and is closely related to economic and educational opportunities. Aims This study aimed to identify factors determining the sexual activity, awareness and use of contraception among college students in Malaysia. Methods A cross-sectional study was conducted among students aged 17–24 years in four colleges of Malaysia. Data were collected via a self-administered multiple response questionnaire. Data analysis was performed on 552 completed questionnaires. Results The mean age of the participants was 19.7±1.6 years. The majority of the respondents were females, Malays, residing in rented accommodations. Contraceptive awareness, sexual activity and use of contraception increased significantly with age of the respondents and were more in males. Better contraceptive awareness was found in those staying away from parents and those studying in colleges with urban exposure. Almost 40 per cent respondents had indulged in sexual activity but only 37 per cent reported use of contraception. A significantly higher proportion of respondents who did not use contraception were females, those in the age group of 19–20 years old and those who were studying in colleges with rural exposure. Male students were more likely to engage in sexual activity and use contraception compared to females. Conclusion There is a need to impart sexual and reproductive health knowledge during the adolescent period so that young people can make informed choices and be motivated to use of contraceptives effectively.

    There are some apparently healthy male rats that fail to mate after repeated testing with receptive females. We have previously shown that these "non-copulator (NC)" males show no partner preference for a receptive female when given the opportunity to physically interact with a sexually receptive female or a sexually active male. We also demonstrated that although NC males prefer odors from estrous females to odors from anestrous females, this preference is significantly reduced in comparison to the preference displayed by copulating (C) males. The aim of the present study was to evaluate in NC males sexual incentive motivation, that is, the approach behavior of male rats to either a sexually receptive female or a sexually active male in a test where the subjects can smell, hear, and see the stimulus animal but prevents their physical interaction. In addition, we determined whether NC rats have alterations in their ability to detect odors from conspecifics or odors related to food. In the detection of odors from conspecifics, we determined if these NC males are sexually attracted toward odors from receptive females or sexually active males. For food-related odors, we quantified the time it took the subjects to locate a hidden a piece of apple. Finally, using the induction of Fos-immunoreactivity (Fos-IR) as an index of neuronal activation, we compared the response of the vomeronasal projection pathway (VN pathway) of C and NC male rats exposed to estrous bedding. Males without sexual experience (WSE) were included in all experiments to determine the importance of previous heterosexual experience in the different behavioral tests and in the activity of the VN pathway. In the sexual incentive motivation test, we found that C and WSE male rats have a clear preference for estrous females over sexually active males, whereas NC male rats showed no preference. In odor tests, our results showed that C males had a clear preference for odors from estrous females as opposed

It was previously demonstrated in male rats that methamphetamine (Meth), when administered concurrently with sexual behavior results in impairment of inhibition of sexual behavior in a conditioned sex aversion (CSA) paradigm where mating is paired with illness. This is indicative of maladaptive sex behavior following Meth and sex experience. The present study examined the neural pathways activated during inhibition of sexual behavior in male rats and the effects of concurrent Meth and sexual behavior on neural activity, using ERK phosphorylation (pERK). First, exposure to conditioned aversive stimuli in males trained to inhibit sexual behavior in the CSA paradigm increased pERK expression in medial prefrontal (mPFC), orbitofrontal cortex (OFC) and areas in striatum and amygdala. Second, effects of concurrent Meth and sex experience were tested in males that were exposed to four daily sessions of concurrent Meth (1 mg/kg) or saline and mating and subsequently exposed to CSA one week after last treatment. Meth and mating-treated males showed significant impairment of inhibition of mating, higher pERK expression under baseline conditions, and disrupted pERK induction by exposure to the conditioned aversive stimuli in mPFC and OFC. These alterations of pERK occurred in CaMKII-expressing neurons, suggesting changes in efferent projections of these areas. Altogether, these data show that concurrent Meth and mating experience causes maladapative sexual behavior that is associated with alterations in neural activation in mPFC and OFC.

    In vivo microdialysis was used to monitor extracellular concentrations of dopamine (DA), and its metabolites dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) in the nucleus accumbens and dorsal striatum of sexually active female rats during tests of locomotor activity, exposure to a novel chamber, exposure to sex odors, the presentation of a sexually active male rat, and copulation. DA increased slightly but significantly in the nucleus accumbens when a sexually active male was placed behind a wire-mesh screen, and further during copulation. DA also increased significantly in the dorsal striatum during copulation; however, the magnitude of this effect was significantly lower than that observed in the nucleus accumbens. The metabolites DOPAC and HVA generally followed DA with a delay, and increased significantly during copulation in both regions. In contrast, forced locomotion on a rotating drum, exposure to a novel testing chamber, and exposure to sex odors did not increase DA significantly in either region, although forced locomotion increased DOPAC significantly in both regions, and HVA significantly in the nucleus accumbens. The magnitude of DA release in the nucleus accumbens was significantly greater during copulation than running, whereas no significant difference was detected for striatal DA release between these two behavioral conditions. These results indicate that novelty or locomotor activity alone do not account for the increase in DA observed in the nucleus accumbens of female rats during copulation, and suggest that DA transmission in the nucleus accumbens is associated with anticipatory and consummatory aspects of sexual activity, as it is in male rats. In the dorsal striatum, however, DA release during copulation may reflect an increase in locomotor activity associated with active pacing of the male.

    Sexual activity is a multifaceted activity, involving complex interactions between the nervous system, the endocrine system, the vascular system and a variety of structures that are instrumental in sexual excitement, intercourse and satisfaction. Sexual function has three components i.e., desire, arousal and orgasm. Many sexual dysfunctions can be categorized according to the phase of sexual response that is affected. In actual clinical practice however, sexual desire, arousal and orgasmic di...

  3. Internet Sexualities

    Science.gov (United States)

    Döring, Nicola

    The term “internet sexuality” (or OSA, online sexual activities) refers to sexual-related content and activities observable on the internet (cf. Adams, Oye, & Parker, 2003; Cooper, McLoughlin, & Campbell, 2000; Leiblum & Döring, 2002). It designates a variety of sexual phenomena (e.g., pornography, sex education, sexual contacts) related to a wide spectrum of online services and applications (e.g., websites, online chat rooms, peer-to-peer networks). If an even broader range of computer networks - such as the Usenet or bulletin board systems - is included in this extensional definition, one speaks of “online sexuality” or “cybersexuality.”

  4. Frequent observation: sexualities, self-surveillance, confession and the construction of the active patient.

    Following Foucault's analyses of the development of the disciplinary power of the medical gaze, this paper describes the themes that are relocating the 'active patient' as the central object of health scrutiny by professionals. A key element in these discourses has been the deployment of power through disciplinary knowledge and techniques of social control through ritual forms of confession, thereby positing the patient/client as the subject of self-surveillance. The individual is also engaged their own sexuality, performativity and 'truths' of sexual experience. These Foucauldian insights have constructed the notion of surveillance medicine, whereby with the assistance of professional technologies, not only the patient's body but also the 'self' can be probed through incitement to confess. However, the actor is not docile; resistances to disciplinary techniques are evident and within the professional practices of the clinic, there is resistance to the power of the erotic. The paper draws on recent research on the social construction of male sexualities in the fields of genitourinary practice, and explores how the ceremonial practices of the clinic engage with the rise of surveillance medicine and the medicalisation of everyday life. The individual actor is exhorted to engage in increased sexual and medical self-surveillance and to be recruited in the project of becoming an 'active patient'. It concludes with an examination of some of the implications this surveillance of self may have for practitioners in terms of power and the professional lens through which the sexualised, symbolic body is viewed.

    Cortical motor areas are influenced not only by peripheral sensory afferents and prefrontal association areas, but also by the basal ganglia, specifically the striatum. The dorsomedial striatum (DMS) and dorsolateral striatum are involved in both spatial and stimulus-response learning; however, each of these areas may mediate different components of learning. The aim of the study is to determine the effect of electrolytic lesion to the DMS on the learning and performance of sexual behaviour and locomotor activity in male rats. Once the subjects had learned to perform motor tests of balance, maze navigation, ramp ascent, and sexual behaviour, they underwent electrolytic lesion to the DMS. Five days later, the tests were repeated on 2 occasions and researchers compared performance latencies for each test. Average latency values for performance on the maze and balance tests were higher after the lesion. However, the average values for the ramp test and for sexual behaviour did not differ between groups. Electrolytic lesion of the DMS modifies the performance of locomotor activity (maze test and balance), but not of sexual behaviour. Copyright © 2015 Sociedad Española de Neurología.

    Although the initiation of sexual behavior is common among adolescents and young adults, some individuals express this behavior in a manner that significantly increases their risk for negative outcomes including sexually transmitted infections. Based on accumulating evidence, we have hypothesized that increased sexual risk behavior reflects, in part, an imbalance between neural circuits mediating approach and avoidance in particular as manifest by relatively increased ventral striatum (VS) activity and relatively decreased amygdala activity. Here, we test our hypothesis using data from seventy 18- to 22-year-old university students participating in the Duke Neurogenetics Study. We found a significant three-way interaction between amygdala activation, VS activation, and gender predicting changes in the number of sexual partners over time. Although relatively increased VS activation predicted greater increases in sexual partners for both men and women, the effect in men was contingent on the presence of relatively decreased amygdala activation and the effect in women was contingent on the presence of relatively increased amygdala activation. These findings suggest unique gender differences in how complex interactions between neural circuit function contributing to approach and avoidance may be expressed as sexual risk behavior in young adults. As such, our findings have the potential to inform the development of novel, gender-specific strategies that may be more effective at curtailing sexual risk behavior.

    Amphibian spinal neurons in culture possess both rapidly inactivating and sustained calcium-dependent potassium current components, similar to those described for other cells. Divalent cation-dependent whole-cell outward currents were isolated by subtracting the voltage-dependent potassium currents recorded from Xenopus laevis neurons in the presence of impermeant cadmium from the currents produced without cadmium but in the presence of permeant divalent cations. These concentrations of permeant ions were low enough to avoid contamination by macroscopic inward currents through calcium channels. Calcium-dependent potassium currents were reduced by 1 ..mu..M tetraethylammonium. These currents can also be activated by barium or strontium. Barium as well as calcium activated outward currents in young neurons (6-8 hr) and in relatively mature neurons (19-26 hr in vitro). However, barium influx appeared to suppress the sustained voltage-dependent potassium current in most cells. Barium also activated at least one class of potassium channels observed in excised membrane patches, whole blocking others. The blocking action may have masked and hindered detection of the stimulatory action of barium in other systems.

    Endothelial nitric oxide synthase (eNOS) has an important role in erection, and it also affects aspects of sexual behavior. In this experiment, we determined whether a compound enhancing the activity of eNOS, Impaza, could stimulate any aspect of sexual behavior and increase penis length in rats with a high baseline of sexual activity. For comparison, the PDE5 inhibitor sildenafil was included. Male rats were orally treated with Impaza or sildenafil for 28 days. Impaza (3 ml kg(-1)) was given daily while sildenafil (3 mg kg(-1)) was given twice weekly. Tests for sexual incentive motivation and copulatory behavior were performed just before drug treatment and at days 7, 14 and 28 of treatment. In addition, the length of the protruding penis at mount, intromission and ejaculation was measured. Impaza but not sildenafil increased penis length at mount after 14 and 28 days of treatment. The compounds failed to modify sexual incentive motivation or copulatory behavior. It is suggested that Impaza enhanced intracavernous pressure, as such a pressure increase is the most likely explanation for enhanced penis length at mount. This effect, together with an absence of motivational actions, suggests that Impaza may be the most valuable treatment for erectile dysfunction.

    Sexual problems are common during pregnancy, but the proportion of pregnant women who experience sexual distress is unknown. In non-pregnant samples, sexual distress is associated with lower sexual and relationship satisfaction. To identify the proportion of women experiencing sexual distress during pregnancy and to compare the sexual and relationship satisfaction of women who report sexual distress during pregnancy with that of women without distress. Two-hundred sixty-one pregnant women completed a cross-sectional online survey. Women completed validated measurements of sexual functioning (Female Sexual Function Index; score relationship satisfaction (Couples Satisfaction Index). Overall, 42% of women met the clinical cutoff for sexual distress. Of sexually active women (n = 230), 26% reported concurrent sexual problems and distress and 14% reported sexual distress in the absence of sexual problems. Sexual distress and/or problems in sexual functioning were linked to lower sexual and relationship satisfaction compared with pregnant women with lower sexual distress and fewer sexual problems. Sexual distress is common during pregnancy and associated with lower sexual and relationship satisfaction. Health care providers should ask pregnant women about feelings of sexual distress. Identifying pregnant women who experience sexual distress and referring them to appropriate resources could help minimize sexual and relationship problems during pregnancy. Vannier SA, Rosen NO.

    2012-01-01

    Despite its relative infrequency, pregnancy is perceived by parents in rural Malawi as a leading cause of school dropout among female students. This paper explores parents' beliefs about adolescent sexual activity and schoolgirl pregnancy and how these perceptions frame parents' aspirations and expectations about girls' schooling. In-depth interviews were collected in rural Malawi from 60 adults aged 25-50 who were the parent of at least one school-aged child. Four themes emerged from the data: how expectations about sexual activity frame parental expectations about schooling duration and dropout, the loss of parental control, the negative influence of classmates and schools as unsafe environments. These concerns frame how parents consider a daughter's schooling prospects and are active even for parents whose daughters are not sexually active or who are not yet old enough to have gone through puberty. Although all parents aspire for their children to attend secondary school, these perceptions of daughters' relative risk weaken parents' motivation to encourage daughters to remain in school.

    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

    Among gay and bisexual men (GBM), a syndemic describes a situation in which negative conditions (e.g., childhood sexual abuse, intimate partner violence, depression, polysubstance use) co-occur such to amplify HIV risk. Research has suggested that sexual compulsivity (SC) may also be a syndemic condition. Between 2011 and 2013, 368 highly sexually active (9+ male partners in 90 days) GBM completed a survey of syndemic factors as well as measures of sexual compulsivity (Sexual Compulsivity Scale [SCS]) and hypersexuality (hypersexual disorder screening inventory [HDSI]). Based on scores on the SCS and HDSI, participants were organized into three groups-negative on both ("Neither SC nor HD"); positive on the SCS only ("SC Only"), and positive on both the SCS and the HDSI ("Both SC and HD"). We found support for the utility of a three-group classification of sexual compulsivity/hypersexuality as one of the syndemic factors that contribute to HIV risk. The average number of syndemic factors experienced was lowest among those who experienced Neither SC nor HD and highest among the group that experienced Both SC and HD, with those experiencing SC Only falling between the two other groups. This study provided further evidence that sexual compulsivity/hypersexuality is a contributing factor to the syndemics model of HIV risk for GBM and that considering three levels of severity (i.e., SC along with HD) led to stronger model predictions than considering SC alone. SC/HD severity provides another modifiable target for HIV prevention intervention development.

    It has been well established that both applied and endogenous electric fields can modulate neuronal activity in various preparations. In this paper, we present the effects of applied currents on spontaneous epileptiform activity in the CA1 region of the rat hippocampus. A computer-controlled system was designed to detect the spontaneous abnormal activity and then apply current pulses of programmable amplitude with monopolar electrodes in the stratum pyramidale. The epileptiform activity was generated by subperfusion of the neural tissue with an elevated potassium artificial cerebrospinal fluid (CSF) solution. Extracellular recordings showed that the interictal bursts could be fully suppressed in 90% of the slices by subthreshold currents with an average amplitude of 12.5 microA. Intracellular recordings showed that the anodic currents generated hyperpolarization of the somatic membrane thereby suppressing neuronal firing. This inhibitory effect of applied current pulses is important for the understanding of electric field effects on abnormal neuronal activity and could be an effective means of preventing the spread of epileptiform activity.

    Current sexuality education programs vary widely in the accuracy of content, emphasis, and effectiveness. Data have shown that not all programs are equally effective for all ages, races and ethnicities, socioeconomic groups, and geographic areas. Studies have demonstrated that comprehensive sexuality education programs reduce the rates of sexual activity, sexual risk behaviors (eg, number of partners and unprotected intercourse), sexually transmitted infections, and adolescent pregnancy. One key component of an effective program is encouraging community-centered efforts. In addition to counseling and service provision to individual adolescent patients, obstetrician-gynecologists can serve parents and communities by supporting and assisting sexuality education. Because of their knowledge, experience, and awareness of a community's unique challenges, obstetrician-gynecologists can be an important resource for sexuality education programs.

    Wartime rape is an atrocity with long-lasting impacts not only on victims but whole societies. In this brief report, we present data on experience and witness of sexual violence during World War II (WWII) and subsequent time of occupation and on indicators of mental health in a sample of elderly Austrians. Interviews of 298 elderly Austrians from a larger epidemiological study on WWII traumatization were analyzed for the impact of experience and witness of sexual violence during the wartime committed by occupational forces. Interviews comprised a biographical/historical section and psychological measures (BSI, TLEQ, PCL-C). Participants were recruited in all nine provinces of Austria with respect to former zones of occupation (Western Allied/Soviet). Twelve persons reported direct experience of sexual violence, 33 persons witnessed such atrocities. One third of the victims and 18.2% of the witnesses reported post-traumatic stress disorder (PTSD full/subthreshold). Sexual violence occurred more often in the former Soviet zone. Victims and witnesses displayed higher odds of post-traumatic symptoms and symptoms of depression and phobic fear than non-victims. Furthermore, witnesses displayed higher levels of aggression compared to victims and non-witnesses. Our results corroborate previous findings that wartime rape has long-lasting effects over decades on current mental health and post-traumatic distress in victims and witnesses. We recommend integration of psychotraumatological knowledge on consequences of sexual violence on mental health into geriatric care and the education of dedicated personnel.

    A survey of 3820 school children in England aged 13-16 years examined sexual activity using the Transtheoretical Model (TTM) Stages of Change. A quarter (26%) of teens were sexually experienced, 44.8 per cent did not use contraception and 48.9 per cent did not use condoms, every time. Past history of condom and contraceptive use, and partner willingness to use condoms were the best predictors of being in Action or Maintenance stage for condom use. Of virgins, 19.82 per cent were in Contemplation or Preparation stages for intercourse, and 85.4 per cent would use condoms every time. Sex education should be tailored to Stage, and signposting to sexual health and contraception services.

    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

    We examine the spatial and temporal relationship between coronal structures observed with the soft X-ray telescope (SXT) on board the Yohkoh spacecraft and the vertical electric current density derived from photospheric vector magnetograms obtained using the Stokes Polarimeter at the Mees Solar Observatory. We focus on a single active region: AR 6952 which we observed on 7 days during 1991 December. For 11 independent maps of the vertical electric current density co-aligned with non-flaring X-ray images, we search for a morphological relationship between sites of high vertical current density in the photosphere and enhanced X-ray emission in the overlying corona. We find no compelling spatial or temporal correlation between the sites of vertical current and the bright X-ray structures in this active region.

  7. Sexuality and Islam.

    This paper deals with three major questions: (1) What are the sexual norms defined by the sacred texts (Koran and Sunna)? (2) What are the sexual practices currently observed among Moslems? (3) To which extent are current sexual practices of Moslems dissociated from Islamic sexual norms? Sexual standards in Islam are paradoxical: on the one hand, they allow and actually are an enticement to the exercise of sexuality but, on the other hand, they discriminate between male and female sexuality, between marital and pre- or extramarital sexuality, and between heterosexuality and homosexuality. Men are given more rights with regard to the expression of their sexuality; women are forbidden to have extramarital sex (with their slaves) and both genders to have homosexual relationships. The combination of these paradoxical standards with modernisation leads to the current back and forth swing of sexual practices between repression and openness. Partial modernisation leads to greater sexual tolerance. But restrictive sexual standards have gathered strength and have become idealised as a result of the current radicalisation of Islam. This swing of the pendulum between repression and openness is illustrated by phenomena such as public harassment, premarital sexuality, female pleasure, prostitution, and homosexuality. Currently, Islam is not any more the only reference which provides guidance concerning sexual practices but secularisation of sexual laws is still politically unthinkable today. So the only solution is to achieve reform in the name of Islam, through the reinterpretation of repressive holy texts.

  8. Predator cat odors activate sexual arousal pathways in brains of Toxoplasma gondii infected rats.

    Directory of Open Access Journals (Sweden)

    Patrick K House

    Full Text Available Cat odors induce rapid, innate and stereotyped defensive behaviors in rats at first exposure, a presumed response to the evolutionary pressures of predation. Bizarrely, rats infected with the brain parasite Toxoplasma gondii approach the cat odors they typically avoid. Since the protozoan Toxoplasma requires the cat to sexually reproduce, this change in host behavior is thought to be a remarkable example of a parasite manipulating a mammalian host for its own benefit. Toxoplasma does not influence host response to non-feline predator odor nor does it alter behavior on olfactory, social, fear or anxiety tests, arguing for specific manipulation in the processing of cat odor. We report that Toxoplasma infection alters neural activity in limbic brain areas necessary for innate defensive behavior in response to cat odor. Moreover, Toxoplasma increases activity in nearby limbic regions of sexual attraction when the rat is exposed to cat urine, compelling evidence that Toxoplasma overwhelms the innate fear response by causing, in its stead, a type of sexual attraction to the normally aversive cat odor.

    2015-01-01

    Our aim is to scrutinize the extent to which aspects of body dissatisfaction and relationship variables predict body appearance cognitive distraction during sexual activity (BACDSA) in a sample of men diagnosed with ED. A total of 65 heterosexual Portuguese participants with ED completed a survey that included questions on socio-demographic data as well as body-related and relationship measures. We used the Global Body Dissatisfaction (GBD) Subscale of the Body Attitudes Test; a version of the Contour Drawing Rating Scale; a single item on partner's opinion perceived about one's body appearance; the Global Measure of Relationship Satisfaction; and the Inclusion of Other in Self Scale. Open questions assessed focus on specific body parts during sexual activity and relationship length. Hierarchical multiple regression indicated that only GBD was a significant predictor of BACDSA, contrary to the relationship measures that showed no significant predictive effect (R(2) =0.47). Our results support the important role of individual factors on explanatory models of sexual dysfunctions, suggesting that interventions addressing individual factors that affect BACDSA may be of preference.

    This study aimed to identify risk and protective factors associated with sexual activity among Malaysian adolescents. Data from the World Health Organization Global School-based Student Health Survey 2012 were analyzed. A total of 23 645 students aged 12 to 17 years responded using self-administered validated questionnaire. The overall prevalence of reported ever-had sex was 8.3%. Logistic regression analysis revealed that ever-had sex was positively significantly associated with ever-used drugs (adjusted odds ratio [aOR] = 7.71; 95% confidence interval [CI] = 6.51-9.13), and to a lesser extent, ever-smoked (aOR = 1.83; 95% CI = 1.62-2.07) and ever-consumed alcohol (aOR = 1.33; 95% CI = 1.15-2.53). Protective factors against ever-had sex were having a close friend (aOR = 0.63; 95% CI = 0.50-0.81), parental bonding (aOR = 0.72; 95% CI = 0.65-0.81), supportive peers (aOR = 0.77; 95% CI = 0.69-0.86), and parental connectedness (aOR = 0.88; 95% CI = 0.78-0.99). Although the prevalence of sexual activity among school-going adolescents in Malaysia is relatively low, identifying the risk and protective factors is crucial toward developing an integrated multiple approach to preventing sexual-related problems.

    To assess prediction strategies for pelvic inflammatory disease (PID). One thousand one hundred seventy women were enrolled based on a high chlamydial risk score. Incident PID over a median of 3 years was diagnosed by either histologic endometritis or Centers for Disease Control and Prevention criteria. A multivariable prediction model for PID was assessed. Women enrolled using the risk score were young, single, sexually active, and often had prior sexually transmitted infections. Incident PID was common (8.6%). From 24 potential predictors, significant factors included age at first sex, gonococcal/chlamydial cervicitis, history of PID, family income, smoking, medroxyprogesterone acetate use, and sex with menses. The model correctly predicted 74% of incident PID; in validation models, correct prediction was only 69%. Our data validate a modified chlamydial risk factor scoring system for prediction of PID. Additional multivariable modeling contributed little to prediction. Women identified by a threshold value on the chlamydial risk score should undergo intensive education and screening.

    Garcia, Frederico Duarte; Thibaut, Florence

    2010-09-01

    The potential adverse consequences, personal distress, shame and guilt presented by patients who suffer from sexual addiction require a more in-depth understanding of the phenomenology and psychobiology of this disorder. A bibliographic review was conducted using MEDLINE and EBSCO databases with the following keywords: "sexual addiction," "hypersexuality," "compulsive sexual behavior," "behavioural addiction," "treatment," and "addiction." Several conceptualizations of excessive nonparaphilic sexual disorder have been proposed based on the models of, respectively, obsessive compulsive disorder, impulse control disorder, out of control excessive sexual disorder, and addictive disorder. Despite the lack of robust scientific data, a number of clinical elements, such as the frequent preoccupation with this type of behavior, the time spent in sexual activities, the continuation of this behavior despite its negative consequences, the repeated and unsuccessful efforts made to reduce the behavior, are in favor of an addictive disorder. In addition there is a high comorbidity between excessive sexual behavior and other addictive behaviors. The phenomenology of excessive nonparaphilic sexual disorder favors its conceptualization as an addictive behavior, rather than an obsessive-compulsive, or an impulse control disorder. Moreover, the criteria that are quite close to those of addictive disorders were recently proposed for the future DSM-V in order to improve the characterization of this condition. Finally, controlled studies are warranted in order to establish clear guidelines for treatment of sexual addiction.

    Asexuality is an emerging identity category that challenges the common assumption that everyone is defined by some type of sexual attraction. Asexuals--those who report feeling no sexual attraction to others--constitute one percent of the population, according to one prominent study. In recent years, some individuals have begun to identify as asexual and to connect around their experiences interacting with a sexual society. Asexuality has also become a protected classification under the antidiscrimination law of one state and several localities, but legal scholarship has thus far neglected the subject. This Article introduces asexuality to the legal literature as a category of analysis, an object of empirical study, and a phenomenon of medical science. It then offers a close examination of the growing community of self-identified asexuals. Asexual identity has revealing intersections with the more familiar categories of gender, sexual orientation, and disability, and inspires new models for understanding sexuality. Thinking about asexuality also sheds light on our legal system. Ours is arguably a sexual law, predicated on the assumption that sex is important. This Article uses asexuality to develop a framework for identifying the ways that law privileges sexuality. Across various fields, these interactions include legal requirements of sexual activity, special carve-outs to shield sexuality from law, legal protections from others' sexuality, and legal protections for sexual identity. Applying this framework, the Article traces several ways that our sexual law burdens, and occasionally benefits, asexuals. This Article concludes by closely examining asexuality's prospects for broader inclusion into federal, state, and local antidiscrimination laws.

    Men who have sex with men (MSM) are the group most at risk for HIV and represent the majority of new infections in the United States. Rates of childhood sexual abuse (CSA) among MSM have been estimated as high as 46 %. CSA is associated with increased risk of HIV and greater likelihood of HIV sexual risk behavior. The purpose of this study was to identify the relationships between CSA complexity indicators and mental health, substance use, sexually transmitted infections, and HIV sexual risk among MSM. MSM with CSA histories (n = 162) who were screened for an HIV prevention efficacy trial completed comprehensive psychosocial assessments. Five indicators of complex CSA experiences were created: CSA by family member, CSA with penetration, CSA with physical injury, CSA with intense fear, and first CSA in adolescence. Adjusted regression models were used to identify relationships between CSA complexity and outcomes. Participants reporting CSA by family member were at 2.6 odds of current alcohol use disorder (OR 2.64: CI 1.24-5.63), two times higher odds of substance use disorder (OR 2.1: CI 1.02-2.36), and 2.7 times higher odds of reporting an STI in the past year (OR 2.7: CI 1.04-7.1). CSA with penetration was associated with increased likelihood of current PTSD (OR 3.17: CI 1.56-6.43), recent HIV sexual risk behavior (OR 2.7: CI 1.16-6.36), and a greater number of casual sexual partners (p = 0.02). Both CSA with Physical Injury (OR 4.05: CI 1.9-8.7) and CSA with Intense Fear (OR 5.16: CI 2.5-10.7) were related to increased odds for current PTSD. First CSA in adolescence was related to increased odds of major depressive disorder. These findings suggest that CSA, with one or more complexities, creates patterns of vulnerabilities for MSM, including post-traumatic stress disorder, substance use, and sexual risk taking, and suggests the need for detailed assessment of CSA and the development of integrated HIV prevention programs that address mental health and

    The current study examined sexual victimization and two barriers to young women's sexual assertiveness: fear of sexual powerlessness and cognitive emotion dysregulation. College women (N = 499) responded to surveys and indicated that fear of sexual powerlessness and, to a lesser extent, cognitive emotion dysregulation were barriers to sexual assertiveness. Compared with nonvictims, sexually victimized women had greater problems with sexual assertiveness, fear of sexual powerlessness, and cognitive emotion dysregulation. Among victims, fear of sexual powerlessness and emotion dysregulation interacted to impede sexual assertiveness. Findings support targeting identified barriers in interventions to improve sexual assertiveness and reduce risk for unwanted sexual experiences and sexual victimization.

    In Venezuela, members of a social and sexual partner networking site for men who have sex with men (MSM) completed an online survey regarding sexual behaviours and HIV medical care. Among the 2851 respondents, self-reported HIV prevalence was 6.6%. Of participants living with HIV, 73.2% reported taking antiretroviral medication and 56.6% reported complete adherence within the past month. Participants living with HIV were more likely to be older (aOR = 1.04 per one-year increase in age, 95% CI: 1.02, 1.06) and diagnosed with a sexually transmitted infection in the previous year (aOR 3.26, 95% CI: 2.11, 5.04). These data provide further understanding of the HIV epidemic among MSM in Venezuela, and potential targets for HIV prevention interventions.

    Ecological Momentary Assessment (EMA) was used to investigate associations between, and variations in, ejaculatory control and ejaculation latency time (ELT) over repeated measurements of sexual activities. Differences between measures recorded in partnered or non-partnered settings were also investigated. The sample consisted of 21 male Finns aged 18 years or above, contributing a total of 158 reports of partnered and non-partnered sexual activities over a six-week period. In the context of non-partnered sexual activities, after controlling for within-subjects dependence, ELTs between events were predictive of one another, but ELT did not predict ejaculatory control when measured simultaneously, nor at subsequent events. Also, ejaculatory control could not predict simultaneously measured ELT or ejaculatory control at subsequent events. During partnered sexual activities, both ejaculatory control and ELT could be accurately predicted by observing ejaculatory control at prior events. In this context, ejaculatory control could also reliably predict simultaneously measured ELT. ELT or ejaculatory control during partnered sexual activity could not be predicted by observing ELT at prior events. Between-event correlations were generally low, indicating considerable variation in ejaculatory functioning over time. EMA is a thrifty assessment method for studying variations in ejaculatory function, and is likely suitable for studying sexual dysfunctions in general.

    Acne is a common disease among young people, which could have a serious impact on quality of life. Based on a survey using the quotas method on a large sample of the French population, we studied the impact of acne on feelings of stress, fatigue upon waking, sleep disorders and sexual activity. We did not establish any relationship to sleep disorders, but clearly ascertained that people with acne (n = 1,375) feel more stressed and have less sexual intercourse. Hence, 18% of people from acne group declared to be stressed every day (13.9% in control group) and 37.5% had no sexual intercourse (20.4% in control group; n = 891). To our knowledge, this is the first study to show that fatigue upon waking is strongly associated with the presence of acne (65.4% versus 58.4%). This study emphasises the fact that acne could have a deep resounding impact on the lives of people suffering from the disease.

    Sexual esteem is an integral psychological aspect of sexual health (Snell & Papini, 1989 ), yet it is unclear whether sexual esteem is associated with sexual health behavior among heterosexual men and women. The current analysis used a normative framework for sexual development (Lefkowitz & Gillen, 2006 ; Tolman & McClelland, 2011 ) by examining the association of sexual esteem with sexual behavior, contraception use, and romantic relationship characteristics. Participants (N = 518; 56.0% female; mean age = 20.43 years; 26.8% identified as Hispanic/Latino; among non-Hispanic/Latinos, 27.2% of the full sample identified as European American, 22.4% Asian American, 14.9% African American, and 8.7% multiracial) completed Web-based surveys at a large Northeastern university. Participants who had oral sex more frequently, recently had more oral and penetrative sex partners (particularly for male participants), and spent more college semesters in romantic relationships tended to have higher sexual esteem than those who had sex less frequently, with fewer partners, or spent more semesters without romantic partners. Sexually active male emerging adults who never used contraception during recent penetrative sex tended to have higher sexual esteem than those who did use it, whereas female emerging adults who never used contraception tended to have lower sexual esteem than those who did use it. Implications of these results for the development of a healthy sexual self-concept in emerging adulthood are discussed.

    To assess the association between current active and passive tobacco smoking and living with a same-sex partner in Spain. We analysed data from two cross-sectional national surveys of the Spanish population 15 years and older (2011-Encuesta Nacional de Salud en España and 2014-Encuesta Europea de Salud en España). Analyses included only people living with their partner. Associations were calculated using multiple logistic regressions adjusting for gender, social class and age. Current active and passive smoking were significantly associated with living with same sex partners (odds ratio: 2.71 and 2.88), and particularly strong among women. Spanish adults living with same-sex partners are at higher risk of active and passive smoking. This risk varies by gender. Spanish national surveys should include items on sexual orientation for improved data on health disparities. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

  8. The three-step process of self-objectification: potential implications for adolescents' body consciousness during sexual activity.

    Vandenbosch, Laura; Eggermont, Steven

    2014-01-01

    A three-wave panel study with intervals of six months was conducted to examine the relationships between internalization of appearance ideals, body surveillance, valuing appearance over competence, and body consciousness during sexual activity among 238 Belgian adolescents who had engaged in sexual intercourse. Consistent with predictions, structural equation modeling indicated that greater internalization of appearance ideals at Wave 1 contributed to increased body surveillance and valuing appearance over competence at Wave 2. Body surveillance at Wave 2 and internalization at Wave 1 predicted higher body consciousness during sexual activity at Wave 3. Gender did not moderate these results, as model paths were similar in strength for girls and boys. These results further implicate the consequences of internalizing sociocultural practices that objectify boys and girls regarding adolescents' initial sexual experiences.

  9. Current concepts of active vasodilation in human skin

    Science.gov (United States)

    Wong, Brett J.; Hollowed, Casey G.

    2017-01-01

    ABSTRACT In humans, an increase in internal core temperature elicits large increases in skin blood flow and sweating. The increase in skin blood flow serves to transfer heat via convection from the body core to the skin surface while sweating results in evaporative cooling of the skin. Cutaneous vasodilation and sudomotor activity are controlled by a sympathetic cholinergic active vasodilator system that is hypothesized to operate through a co-transmission mechanism. To date, mechanisms of cutaneous active vasodilation remain equivocal despite many years of research by several productive laboratory groups. The purpose of this review is to highlight recent advancements in the field of cutaneous active vasodilation framed in the context of some of the historical findings that laid the groundwork for our current understanding of cutaneous active vasodilation.

    The properties of glutamate-activated excitatory currents on the gm6 muscle from the foregut of the spiny lobsters Panulirus argus and interruptus and the crab Cancer borealis were examined using either noise analysis, analysis of synaptic current decays, or slow iontophoretic currents. The properties of acetylcholine currents activated in nonjunctional regions of the gm6 muscle were also examined. At 12 degrees C and -80 mV, the predominant time constant of power spectra from glutamate-activated current noise was approximately 7 ms and the elementary conductance was approximately 34 pS. At 12 degrees C and -80 mV, the predominant time constant of acetylcholine-activated channels was approximately 11 ms with a conductance of approximately 12 pS. Focally recorded glutamatergic extracellular synaptic currents on the gm6 muscle decayed with time constants of approximately 7-8 ms at 12 degrees C and -80 mV. The decay time constant was prolonged e-fold about every 225-mV hyperpolarization in membrane potential. The Q10 of the time constant of the synaptic current decay was approximately 2.6. The voltage dependence of the steady-state conductance increase activated by iontophoretic application of glutamate has the opposite direction of the steady-state conductance activated by cholinergic agonists when compared on the gm6 muscles. The glutamate-activated conductance increase is diminished with hyperpolarization. The properties of the marine crustacean glutamate channels are discussed in relation to glutamate channels in other organisms and to the acetylcholine channels found on the gm6 muscle and the gm1 muscle of the decapod foregut (Lingle and Auerbach, 1983).

Does the brain respond in similar way to such reward signals even when they are "unseen", i.e., presented in a way that prevents their conscious recognition? Can the brain response to "unseen" reward cues predict the future affective response to recognizable versions of such cues, revealing a link between affective/motivational processes inside and outside awareness?We exploited the fast temporal resolution of event-related functional magnetic resonance imaging (fMRI to test the brain response to "unseen" (backward-masked cocaine, sexual, aversive and neutral cues of 33 milliseconds duration in male cocaine patients (n = 22. Two days after scanning, the affective valence for visible versions of each cue type was determined using an affective bias (priming task. We demonstrate, for the first time, limbic brain activation by "unseen" drug and sexual cues of only 33 msec duration. Importantly, increased activity in an large interconnected ventral pallidum/amygdala cluster to the "unseen" cocaine cues strongly predicted future positive affect to visible versions of the same cues in subsequent off-magnet testing, pointing both to the functional significance of the rapid brain response, and to shared brain substrates for appetitive motivation within and outside awareness.These findings represent the first evidence that brain reward circuitry responds to drug and sexual cues presented outside awareness. The results underscore the sensitivity of the brain to "unseen" reward signals and may represent the brain's primordial signature for desire. The limbic brain response to reward cues outside awareness may represent a potential vulnerability in disorders (e.g., the addictions for whom poorly-controlled appetitive motivation is a central feature.

    Psychosocial benefits of activism include increased empowerment, social connectedness, and resilience. Yet sexual minority women (SMW) and transgender individuals with multiple oppressed statuses and identities are especially prone to oppression-based experiences, even within minority activist communities. This study sought to develop an empirical model to explain the diverse meanings of social justice activism situated in SMW and transgender individuals' social identities, values, and experiences of oppression and privilege. Using a grounded theory design, 20 SMW and transgender individuals participated in initial, follow-up, and feedback interviews. The most frequent demographic identities were queer or bisexual, White, middle-class women with advanced degrees. The results indicated that social justice activism was intensely relational, replete with multiple benefits, yet rife with experiences of oppression from within and outside of activist communities. The empirically derived model shows the complexity of SMW and transgender individuals' experiences, meanings, and benefits of social justice activism.

    In industrialized societies the progression of natural selection has been determined and in many cases superseded by social evolution. In the case of reproduction, there has been a decline and delay of childbearing without diminished sexual activity. While this has value for these societies, there are penalties associated with barren cycles. These include increases in endometriosis and breast and genital cancer. There also are associated issues regarding population movements that fill the "vacuums" left by underpopulation. These matters are of more than passing interest as we cope with unintended consequences of Man's dominance over the environment and other life forms.

    Nicholas P Vyleta

    Full Text Available BACKGROUND: Caffeine stimulates calcium-induced calcium release (CICR in many cell types. In neurons, caffeine stimulates CICR presynaptically and thus modulates neurotransmitter release. METHODOLOGY/PRINCIPAL FINDINGS: Using the whole-cell patch-clamp technique we found that caffeine (20 mM reversibly increased the frequency and decreased the amplitude of miniature excitatory postsynaptic currents (mEPSCs in neocortical neurons. The increase in mEPSC frequency is consistent with a presynaptic mechanism. Caffeine also reduced exogenously applied glutamate-activated currents, confirming a separate postsynaptic action. This inhibition developed in tens of milliseconds, consistent with block of channel currents. Caffeine (20 mM did not reduce currents activated by exogenous NMDA, indicating that caffeine block is specific to non-NMDA type glutamate receptors. CONCLUSIONS/SIGNIFICANCE: Caffeine-induced inhibition of mEPSC amplitude occurs through postsynaptic block of non-NMDA type ionotropic glutamate receptors. Caffeine thus has both pre and postsynaptic sites of action at excitatory synapses.

    In Venezuela, members of a social and sexual partner-networking site for MSM completed an online survey regarding sexual behaviors and HIV medical care. Among the 3,175 respondents, self-reported HIV prevalence was 7.8%. Of participants living with HIV, 73.2% reported taking antiretroviral medication and, 56.6% reported complete adherence within the past month. Participants living with HIV were more likely to be older (aOR=1.04 per one-year increase in age, 95% CI: 1.02, 1.06) and diagnosed with an STI in the previous year (aOR=32.35,10.2). These data provide further understanding of the HIV epidemic among MSM in Venezuela, and potential targets for HIV prevention interventions. PMID:26378188

This study was therefore carried out to assess the knowledge, attitude, and practice of emergency contraception (EC among college students in Osogbo metropolis. Materials and methods: This descriptive cross-sectional study was carried out among 594 college students in Osogbo metropolis in Osun State, Nigeria, using pretested, semistructured questionnaires. Respondents were selected by multistage sampling. Data were analyzed using SPSS software, version 15. Results: The mean age of the respondents was 23.45 ± 3.63 years. Mean age at first sexual exposure was 19.34 ± 4.34 years. Awareness about EC was fairly high among the respondents, (403, 67.8%, with categorized scoring of outcome variables showing that 60.8% of respondents had good general knowledge and only 27.9% had a positive attitude towards EC. However, only 66 (29.9% of the sexually active respondents had ever used EC before the study, while 26 (21.5% of the 121 sexually active female respondents admitted to having had an abortion.

    The aim of this study was to examine the incidence and antibiotic sensitivity of Ureaplasma urealyticum and Mycoplasma hominis strains cultured from the genital discharges of sexually active individuals who attended our STD outpatient service. Samples were taken with universal swab (Biolab®, Budapest, Hungary) into the Urea-Myco DUO kit (Bio-Rad®, Budapest, Hungary) and incubated in ambient air for 48 h at 37 °C. The determination of antibiotic sensitivity was performed in U9 and arginin broth using the SIR Mycoplasma kit (Bio-Rad®, Budapest, Hungary) under the same conditions. Between 01.05.2008 and 31.12.2011, 373/4,466 (8.35 %) genito-urethral samples with U. urealyticum and 41/4,466 (0.91 %) genito-urethral samples with M. hominis infection were diagnosed in sexually active individuals in the National STD Center, Semmelweis University. U. urealyticum was isolated in 12.54 % in the cervix and 4.1 % in the male urethra, while M. hominis was isolated in 1.33 % in the cervix and 0.51 % in the male urethra. The affected age group was between 21 and 60 years old. U. urealyticum strains were sensitive to tetracycline (95.9 %), doxycycline (97.32 %), and azithromycin (85.79 %), and resistant to erythromycin (81.23 %), clindamycin (75.06 %), and ofloxacin (25.2 %). Cross-resistance occurred in 38.71 % of patients to erythromycin and clindamycin. M. hominis strains were sensitive to clindamycin, ofloxacin, and doxycycline in more than 95 %, to tetracycline in 82.92 %, and no cross-resistance was detected among the antibiotics. Our study confirms that the continuously changing antibiotic resistance of ureaplasmas and mycoplasmas should be followed at least in a few centers in every country, so as to determine the best local therapy options for sexually transmitted infection (STI) patients.

    The basal fungus Allomyces macrogynus (A. macrogynus) produces motile male gametes displaying well-studied chemotaxis toward their female counterparts. This chemotaxis is driven by sirenin, a sexual pheromone released by the female gametes. The pheromone evokes a large calcium influx in the motile gametes, which could proceed through the cation channel of sperm (CatSper) complex. Herein, we report the total synthesis of sirenin in 10 steps and 8% overall yield and show that the synthetic pheromone activates the CatSper channel complex, indicated by a concentration-dependent increase in intracellular calcium in human sperm. Sirenin activation of the CatSper channel was confirmed using whole-cell patch clamp electrophysiology with human sperm. Based on this proficient synthetic route and confirmed activation of CatSper, analogues of sirenin can be designed as blockers of the CatSper channel that could provide male contraceptive agents.

    Sexual fantasies are seen as an important source of information and a modality for treatment procedures in sex therapy programs. While drive-reduction models view fantasy as a symptom of a deficiency state, cognitive-behavioral approaches take fantasies as an index of a satisfying sex life. While current data tend to support the behavioral position, no systematic comparison has been undertaken of men and women with and without sexual distress. This study compared written examples of sexual daydreaming, masturbatory and coital fantasies as well as habitual patterns of employing fantasies during sexual activities of the above mentioned groups. Other psychotherapy clients served as control. Sex differences were sparse and the comparison between distressed and nondistressed tended to support the behavioral position. Although sexual fantasizing is positively related to a satisfying sex life, fantasies are often used for reducing aversive emotions. Subjects older than 35 years showed fewer fantasies and lower correlations between daydreaming and sexual activity.

    This study used arterial spin labeling (ASL) fMRI to measure brain perfusion in a group of healthy men under conditions that closely resembled customary sexual behavior. Serial perfusion measures for 30 min during two self-limited periods of partnered penis stimulation, and during post-stimulatory periods, revealed novel sexual activity-related cerebral blood flow (rCBF) changes, mainly in subcortical parts of the brain. Ventral pallidum rCBF was highest during the onset of penile erection, and lowest after the termination of penis stimulation. The perceived level of sexual arousal showed the strongest positive association with rCBF in the right basal forebrain. In addition, our results demonstrate that distinct subregions of the hypothalamus and cingulate cortex subserve opposite functions during human male sexual behavior. The lateral hypothalamus and anterior part of the middle cingulate cortex showed increased rCBF correlated with penile erection. By contrast, the anteroventral hypothalamus and subgenual anterior cingulate cortex exhibited rCBF changes correlated with penile detumescence after penile stimulation. Continuous rapid and high-resolution brain perfusion imaging during normal sexual activity has provided novel insights into the central mechanisms that control male sexual arousal.

    Stress is thought to alter motivational processes by increasing dopamine (DA) secretion in the brain's "reward system", and its key region, the nucleus accumbens (NAcc). However, stress studies using functional magnetic resonance imaging (fMRI), mainly found evidence for stress-induced decreases in NAcc responsiveness toward reward cues. Results from both animal and human PET studies indicate that the stress hormone cortisol may be crucial in the interaction between stress and dopaminergic actions. In the present study we therefore investigated whether cortisol mediated the effect of stress on DA-related responses to -subliminal-presentation of reward cues using the Trier Social Stress Test (TSST), which is known to reliably enhance cortisol levels. Young healthy males (n = 37) were randomly assigned to the TSST or control condition. After stress induction, brain activation was assessed using fMRI during a backward-masking paradigm in which potentially rewarding (sexual), emotionally negative and neutral stimuli were presented subliminally, masked by pictures of inanimate objects. A region of interest analysis showed that stress decreased activation in the NAcc in response to masked sexual cues (voxel-corrected, pcortisol levels were related to stronger NAcc activation, showing that cortisol acted as a suppressor variable in the negative relation between stress and NAcc activation. The present findings indicate that cortisol is crucially involved in the relation between stress and the responsiveness of the reward system. Although generally stress decreases activation in the NAcc in response to rewarding stimuli, high stress-induced cortisol levels suppress this relation, and are associated with stronger NAcc activation. Individuals with a high cortisol response to stress might on one hand be protected against reductions in reward sensitivity, which has been linked to anhedonia and depression, but they may ultimately be more vulnerable to increased reward

    Objective studies of men's reproductive function are hindered by their reliance on:(i) self-reporting to quantify sexual activity and (ii)masturbation to quantify sperm output rendering both types of estimate vulnerable to unverifiable subjective factors.We therefore examined whether detection of spermatozoa and measurement of prostate-specific antigen (PSA) in urine could provide objective semiquantitative estimates of sperm output and recent ejaculation,respectively,using widely available laboratory techniques.Of 11healthy volunteers who provided urine samples before and at intervals for 5 days after ejaculation,sperm was present in 2/11 men before,and in all 11/11 samples immediately after ejaculation,but by the second and subsequent void,spermatozoa were present in ~10%.PSA was detectable at high levels in all urine samples,peaking at the first post-ejaculatory sample but returning to baseline levels by the second post-ejaculatory void.We conclude that urinary spermatozoa and PSA are objective biomarkers for sperm production and sexual activity,but only for a short-time window until the first post-ejaculatory urine void.Hence,for a single urine specimen,the presence of spermatozoa and PSA are valid biomarkers,reflecting sperm production and recentejaculation only until the next micturition,so their measurement should be restricted to the first morning urine void.

    This study problematizes the literature's conceptualization of sexual compliance, predominantly defined as willing participation in, and consent to, unwanted sexual activity in the absence of immediate partner pressure. Using a feminist theoretical framework, we argue that covert forms of social coercion, including normalized expectations for heterosexual women to participate in sexual activity and maintain relationship satisfaction, ultimately pressure women into participating in unwanted sexual activity. In other words, immediate partner pressure is not necessary for a sexually coercive experience to occur. Results of the current study indicate that relationship control and media influence significantly predict sexual acquiescence, and women acquiesce to unwanted sexual activity in an effort to maintain relationships and partner satisfaction as well as to avoid negative outcomes. Women cite various forms of social coercion, such as fulfilling sexual scripts and relationship obligations, as primary reasons for participating in unwanted sexual activity without resisting their partners. © The Author(s) 2014.

    Full Text Available Introduction In contrast to animal species in which linear relationships exist between hormonal status and sexual behaviour sexuality in human population is not determined so simply by the level of sexual steroids. 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

    Youth and young adults (19-24 years of age) shoulder the burden of sexually transmitted infections accounting for nearly half of all new infections annually. Mobile technology is one way that we have reached this population with safer sex information but challenges exist with the delivery process. The literature between 2010 and 2015 was reviewed for data on safe sex and sexual health information delivered using mobile cell phone devices. A search for relevant databases revealed that 17 articles met our inclusion criteria. Findings suggest that mobile cell phone interventions are an effective mode for delivering safe sex and sexual health information to youth; those at the highest risk may not be able to access cell phones based on availability and cost of the text messages or data plans.

    We describe the first mapping of biological current in a live heart using ultrasound current source density imaging (UCSDI). Ablation procedures that treat severe heart arrhythmias require detailed maps of the cardiac activation wave. The conventional procedure is time-consuming and limited by its poor spatial resolution (5-10 mm). UCSDI can potentially improve on existing mapping procedures. It is based on a pressure-induced change in resistivity known as the acousto-electric (AE) effect, which is spatially confined to the ultrasound focus. Data from 2 experiments are presented. A 540 kHz ultrasonic transducer (f/# = 1, focal length = 90 mm, pulse repetition frequency = 1600 Hz) was scanned over an isolated rabbit heart perfused with an excitation-contraction decoupler to reduce motion significantly while retaining electric function. Tungsten electrodes inserted in the left ventricle recorded simultaneously the AE signal and the low-frequency electrocardiogram (ECG). UCSDI displayed spatial and temporal patterns consistent with the spreading activation wave. The propagation velocity estimated from UCSDI was 0.25 +/- 0.05 mm/ms, comparable to the values obtained with the ECG signals. The maximum AE signal-to-noise ratio after filtering was 18 dB, with an equivalent detection threshold of 0.1 mA/ cm(2). This study demonstrates that UCSDI is a potentially powerful technique for mapping current flow and biopotentials in the heart.

  13. Improved Active Harmonic Current Elimination Based on Voltage Detection.

    Directory of Open Access Journals (Sweden)

    Tianyuan Tan

    Full Text Available With the increasing penetration of power electronic equipment in modern residential distribution systems, harmonics mitigation through the distributed generation (DG interfacing converters has received significant attention. Among recently proposed methods, the so-called active resonance damper (ARD and harmonic voltage compensator (HVC based on voltage detection can effectively reduce the harmonic distortions in selected areas of distribution systems. However, it is found out that when traditional ARD algorithm is used to eliminate harmonic current injected by non-linear loads, its performance is constrained by stability problems and can at most eliminate half of the load harmonic currents. Thus, inspired by the duality between ARD and HVC, this paper presents a novel improved resistive active power filter (R-APF algorithm based on integral-decoupling control. The design guideline for its parameters is then investigated through carefully analyzing the closed-loop poles' trajectory. Computer studies demonstrate that the proposed algorithm can effectively mitigate the load harmonic currents and its performance is much better than traditional ARD based on proportional control.

    This study evaluated the sexual activity and the quality of life in patients with a Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome. The study is based on a series of patients hospitalized for the treatment of MRKH syndrome in CMCO between 1997 and 2010. Through the medical reports, we recovered information about the pathology, the treatment given and the psychological support proposed to or wished by the patients. The patients also had to answer a questionnary concerning the quality of the informations they received about the treatment, the different types of supports proposed and wanted, their life as a couple and how they communicated about their disease. Eleven medical reports have been reviewed. The patients were aged 21 in average at the moment of the treatment. Three patients had some associated malformations. Different methods of treatment were represented (Frank's method, Vecchietti's technique, sigmoid vaginoplasty, McIndoe's technique). Sexual intercourse was assessed as satisfactory by 4 patients. In 8 cases, the partner accepted well the pathology. Only 4 out of the eleven medical reports mentioned a psychological support. Nine out of the eleven patients accepted to answer the questionnary. The review of the literature and our own results show that the patients with MRKH syndrome have a real need for psychological support. They are able to have sexual intercourse that is satisfactory in the domains of excitation, lubrification and desire, especially after treatment. The main problem is the inability to bear children, a problem which might by solved by the future researches about uterus graft and the evolution of the laws concerning gestational surrogacy.

    This paper proposes an adaptive current control method for Hybrid Active Power Filter (HAPF). It consists of a fuzzy-neural controller, identification and prediction model and cost function. The fuzzy-neural controller parameters are adjusted according to the cost function minimum criteria. For this reason, the proposed control method has a capability on-line control clings to variation of the load harmonic currents. Compared to the single fuzzy logic control method, the proposed control method shows the advantages of better dynamic response, compensation error in steady-state is smaller, able to online control is better and harmonics cancelling is more effective. Simulation and experimental results have demonstrated the effectiveness of the proposed control method.

    Full Text Available Introduction: Under current HIV transmission mechanisms operating in Vietnam, women are seen as victims of their male partners. Having multiple sexual partners is one of the well-known risk factors for HIV infection. However, little is known about women's risky sexual behaviour and their vulnerability to HIV in Vietnam. This study aims to explore association between early sexual initiation and the number of lifetime sexual partners in Vietnamese women. Although the Vietnamese culture is socially conservative in this area, identifying women's risky sexual behaviour is important for the protection of women at risk of HIV and other sexually transmitted diseases. Design: A total of 8,791 women, who reported having had sexual intercourse, were included in this analysis of data from the 2011 Multiple Indicator Cluster Survey in Vietnam. Data were collected using two-stage strata sampling, first at the national level and second across six geographical regions (n=8,791. Multivariable logistic regressions describe association between early initiation of a sexual activity and lifetime multiple sexual partners. Results: Early sexual intercourse was significantly associated with having lifetime multiple sexual partners. Women who were aged 19 or younger at first sexual intercourse were over five times more likely to have multiple sexual partners, compared with women whose first sexual intercourse was after marriage; aged 10–14 years (OR=5.9; 95% CI=1.9–18.8 at first intercourse; and aged 15–19 years (OR=5.4; 95% CI=4.0–7.2 at first intercourse. There was significant association with having multiple sexual partners for women of lower household wealth and urban residence, but the association with educational attainment was not strong. Conclusions: The study results call for health and education policies to encourage the postponement of early sexual activity in young Vietnamese women as protection against risky sexual behaviour later in life.

    Sleep disturbance and sexual dysfunction are common in menopause; however, the nature of their association is unclear. The present study aimed to determine whether sleep characteristics were associated with sexual activity and sexual satisfaction. Sexual function in the last year and sleep characteristics (past 4 wk) were assessed by self-report at baseline for 93,668 women age 50 to 79 years enrolled in the Women's Health Initiative (WHI) Observational Study (OS). Insomnia was measured using the validated WHI Insomnia Rating Scale. Sleep-disordered breathing (SDB) risk was assessed using questions adapted from the Berlin Questionnaire. Using multivariate logistic regression, we examined cross-sectional associations between sleep measures and two indicators of sexual function: partnered sexual activity and sexual satisfaction within the last year. Fifty-six percent overall reported being somewhat or very satisfied with their current sexual activity, and 52% reported partnered sexual activity within the last year. Insomnia prevalence was 31%. After multivariable adjustment, higher insomnia scores were associated with lower odds of sexual satisfaction (yes/no) (odds ratio [OR] 0.92, 95% CI, 0.87-0.96). Short sleep duration (<7-8 h) was associated with lower odds of partnered sexual activity (yes/no) (≤5 h, OR 0.88, 95% CI, 0.80-0.96) and less sexual satisfaction (≤5 h, OR 0.88, 95% CI, 0.81-0.95). Shorter sleep durations and higher insomnia scores were associated with decreased sexual function, even after adjustment for potential confounders, suggesting the importance of sufficient, high-quality sleep for sexual function. Longitudinal investigation of sleep and its impact on sexual function postmenopause will clarify this relationship.

    Most research on sexual content in the media has focused on visual images such as those in TV, film, advertisements, and magazines. However, researchers have largely overlooked sexual content in novels. The popularity of novels and the potential for such literature to educate teens on sexual behaviors merits a closer examination into the sexual messages contained in popular adolescent literature. This study content analyzes the top 40 novels targeting adolescents. Results show that adolescent novels are replete with sex-related information, especially in novels targeted to girls. These sexual behaviors range from passionate kissing and romantic ideation to sexual intercourse. Over one third of the instances focus on references to sex, suggestive innuendos, or sexual descriptions; and an additional one third of sexual behavior involved sexual affection in the form of passionate kissing, intimate touching, and playful sexual behavior. Across the 40 books, there were 56 instances of sexual intercourse, most of which involved unmarried couples (94%); and many were in non-committal relationships. Moreover, sexual material rarely dealt with issues of abstinence, safe sex practices, and the health risks associated with sex.

    It is shown that current-activated pressure-assisted densification (CAPAD) is sensitive to the Peltier effect. Under CAPAD, the Peltier effect leads to a significant redistribution of heat within the sample during the densification. The densification of highly p-doped silicon nanoparticles during CAPAD and the properties of the obtained samples are investigated experimentally and by computer simulation. Both, simulation and experiments, indicate clearly a higher temperature on the cathode side and a decreasing temperature from the center to the outer shell. Furthermore, computer simulations provide additional insights into the temperature profile which explain the anisotropic properties of the measured sample.

    The disciplinary goals of the Human Research Program are broadly discussed. There is a critical need to identify gaps in the evidence that would substantiate a skeletal health risk during and after spaceflight missions. As a result, data mining activities will be engaged to gather reviews of medical data and flight analog data and to propose additional measures and specific analyses. Several studies are briefly reviewed which have topics that partially address these gaps in knowledge, including bone strength recovery with recovery of bone mass density, current renal stone formation knowledge, herniated discs, and a review of bed rest studies conducted at Ames Human Research Facility.

    Phthalates, a ubiquitous class of environmental chemicals, may interfere with typical reproductive hormone production both in utero and in adulthood. Although they are best known as anti-androgens, increasingly, evidence suggests that phthalates, particularly di-2-ethylhexyl phthalate (DEHP), may also suppress estrogen production. Given that both androgens and estrogens are essential for sexual function, particularly sexual interest, it is plausible that adult exposure to phthalates alters sexual function. To this end, we used data from 360 women participating in a pregnancy cohort study (the Study for Future Families) to examine whether urinary phthalate metabolite concentrations were associated with two dimensions of self-reported sexual dysfunction in the months prior to conception: lack of sexual interest and vaginal dryness. Women in the highest quartile of urinary concentrations of mono-2-ethyl-5-hydroxyhexyl phthalate, a DEHP metabolite, had 2.58 (95% CI 1.33, 5.00) times the adjusted odds of reporting that they almost always or often lacked interest in sexual activity, and results were similar for mono-2-ethyl-5-oxohexyl phthalate (aOR: 2.56, 95% CI 1.32, 4.95), another DEHP metabolite. Self-reported vaginal dryness was not associated with any phthalate metabolite concentration. This study is novel in its focus on sexual function in relation to environmentally relevant (rather than occupational) exposure to phthalates in adult women and these preliminary findings merit replication in a large, prospective study. Better understanding how adult exposure to phthalates may affect reproductive health, including sexual function, is of public health interest given that virtually all Westerners are exposed to phthalates.

Mobile technology is one way that we have reached this population with safer sex information but challenges exist with the delivery process. The literature between 2010 and 2015 was reviewed for data on safe sex and sexual health information delivered using mobile cell phone devices. A search for relevant databases revealed that 17 articles met our inclusion criteria. Findings suggest that mobile cell phone interventions are an effective mode for delivering safe sex and sexual health information to youth; those at the highest risk may not be able to access cell phones based on availability and cost of the text messages or data plans.

    Research has shown that acute immune activation during the early postnatal period with the Gram-negative endotoxin, lipopolysaccharide (LPS), alters a variety of physiological and behavioural processes in the adult animal. For example, neonatal LPS exposure affects disease susceptibility later in life, though these effects appear to be modulated by time of exposure, sex, and immune stimulus. The current study examined sex differences in the effect of neonatal LPS treatment on the locomotor activity response to adult LPS administration. Male and female Long-Evans rats were treated systemically with either LPS (50 microg/kg) or saline (0.9%) on postnatal days 3 and 5. Later in adulthood (postnatal day 92), all animals were subjected to an adult LPS challenge and were injected (i.p.) with 200 microg/kg LPS. Two hours after injection, animals were placed in a non-novel open-field and locomotor activity was assessed for 30 min. Body weights were determined both at the time of injection and 24h later to examine LPS-induced weight loss. Adult males treated neonatally with LPS exhibited significantly less horizontal and vertical activity in response to the LPS challenge relative to males treated neonatally with saline. This effect was not observed in females. Thus, the current study provides important evidence of sexual dimorphism in the long-term effects of neonatal LPS exposure on the responses to an adult homotypic immune challenge in rats. These findings have potential clinical significance given that neonatal exposure to pathogens is a fairly common occurrence and Gram-negative bacteria are a common cause of neonatal bacterial infections.

    Full Text Available The aim of this work is to assess the level of use of male condom and to identify the main beliefs about condomuse in a sample of 315 teenagers (55,6 % boys and 44,6% girls belonging to secondary schools, with an average ageof 18,27, which represent 23,8 % of the total sample (N= 1323. The results show that 48,1% of the sexuallyactive students use condoms systematically, boys use them more often than girls. The condom use for boys arerelated interference with the sexual pleasure and for girls are related with have sex without taking any risk. In theboys the best predictors of the use are linked to a less sexual activity frequency, owing to considerations about adouble contraceptive and preventive function of the condom, to the feeling of safety when using it, and to feel noembarrasment when buying them. In the girls the best predicgtors of the condom use are little use of the pill, theless frequent «coitus interruptus», and the safety feeling associated to the thought that the romantic atmosphere is notbroken make up.

    Full Text Available Sexual activity is a multifaceted activity, involving complex interactions between the nervous system, the endocrine system, the vascular system and a variety of structures that are instrumental in sexual excitement, intercourse and satisfaction. Sexual function has three components i.e., desire, arousal and orgasm. Many sexual dysfunctions can be categorized according to the phase of sexual response that is affected. In actual clinical practice however, sexual desire, arousal and orgasmic difficulties more often than not coexist, suggesting an integration of phases. Sexual dysfunction can result from a wide variety of psychological and physiological causes including derangements in the levels of sex hormones and neurotrensmitters. This review deals with the biology of different phases of sexual function as well as implications of hormones and neurotransmitters in sexual dysfunction

    With age of marriage rising in Kenya, the period between onset of puberty and first marriage has increased, resulting in higher rates of premarital sexual activity and pregnancy. We assessed the determinants of sexual activity and pregnancy among young unmarried women in urban Kenya. Baseline data from five urban areas in Kenya (Nairobi, Mombasa, Kisumu, Machakos, and Kakamega) collected in 2010 by the Measurement, Learning & Evaluation project were used. Women aged 15-24 years, who had never been married, and were not living with a male partner at the time of survey (weighted n = 2020) were included. Using weighted, multivariate Cox proportional hazard regression and logistic regression analyses, we assessed factors associated with three outcome measures: time to first sex, time to first pregnancy, and teenage pregnancy. One-half of our sample had ever had sex; the mean age at first sex among the sexually-experienced was 17.7 (± 2.6) years. About 15% had ever been pregnant; mean age at first pregnancy was 18.3 (± 2.2) years. Approximately 11% had a teenage pregnancy. Three-quarters (76%) of those who had ever been pregnant (weighted n = 306) reported the pregnancy was unwanted at the time. Having secondary education was associated with a later time to first sex and first pregnancy. In addition, religion, religiosity, and employment status were associated with time to first sex while city of residence, household size, characteristics of household head, family planning knowledge and misconceptions, and early sexual debut were significantly associated with time to first pregnancy. Education, city of residence, household wealth, early sexual debut, and contraceptive use at sexual debut were associated with teenage pregnancy for those 20-24 years. Understanding risk and protective factors of youth sexual and reproductive health can inform programs to improve young people's long-term potential by avoiding early and unintended pregnancies.

    Ca(2+)-activated Cl- channels are expressed in a variety of cell types, including central and peripheral neurones. These channels are activated by a rise in intracellular Ca2+ close to the cell membrane. This can be evoked by cellular events such as Ca2+ entry through voltage- and ligandgated channels or release of Ca2+ from intracellular stores. Additionally, these Ca(2+)-activated Cl currents (ICl(Ca)) can be activated by raising intracellular Ca2+ through artificial experimental procedures such as intracellular photorelease of Ca2+ from "caged" photolabile compounds (e.g. DM-nitrophen) or by treating cells with Ca2+ ionophores. The potential changes that result from activation of Ca(2+)-activated Cl- channels are dependent on resting membrane potential and the equilibrium potential for Cl-. Ca2+ entry during a single action potential is sufficient to produce substantial after potentials, suggesting that the activity of these Cl- channels can have profound effects on cell excitability. The whole cell ICl(Ca) can be identified by sensitivity to increased Ca2+ buffering capacity of the cell, anion substitution studies and reversal potential measurements, as well as by the actions of Cl- channel blockers. In cultured sensory neurones, there is evidence that the ICl(Ca) deactivates as Ca2+ is buffered or removed from the intracellular environment. To date, there is no evidence in mammalian neurones to suggest these Ca(2+)-sensitive Cl- channels undergo a process of inactivation. Therefore, ICl(Ca) can be used as a physiological index of intracellular Ca2+ close to the cell membrane. The ICl(Ca) has been shown to be activated or prolonged as a result of metabolic stress, as well as by drugs that disturb intracellular Ca2+ homeostatic mechanisms or release Ca2+ from intracellular stores. In addition to sensitivity to classic Cl- channel blockers such as niflumic acid, derivatives of stilbene (4,4'diisothiocyanostilbene-2,2'-disulphonic acid, 4-acetamido-4

    Sexual activity after myocardial infarction (MI) is a concern for patients and often a challenge for health care professionals to address. It is widely recognized that most patients, of both sexes, report sexual problems or concerns after MI. However, there are reported differences between men and women. Women with sexual concerns may seek less help from health care providers and are more inclined to conceal them because of cultural barriers. The aim of the current study is to present a comprehensive review of the literature describing women's sexual issues after MI. A systematic search of the relevant literature was performed within international databases, including PubMed/Medline, Scopus, ScienceDirect, and ProQuest, as well as Google Scholar using relevant keywords. Also, Persian electronic databases such as Magiran, Scientific Information Databases, and Iran Medex were searched from the inception to October 2014. Articles focusing on the sexual issues after MI only in women, as well as articles on both sexes where women's results could be separated, were included in this review. A total of 8 articles were included in the final dataset. The main themes of women's sexual concerns after MI were "loss or decrease of sexual activity," "dissatisfaction of sexual relationship," "doubt about resumption time of sexual activity," "fear of reinfarction or sudden death during sexual activity after MI," "knowledge deficit regarding sexual activity after MI," and "poor performance of health care providers in sexual counseling." The results of this review demonstrate that women's post-MI sexual activity is affected by many concerns. The concerns may be a knowledge deficit related to not receiving necessary consultation on this topic. Nurses, as first-line care givers, can provide appropriate consultation and education for patients post-MI. As a result, breaking taboo imposed by cultural barriers, personal assumptions, or lack of confidence on giving sexual consultation may

Participants were from US (n = 103) and Spanish (n = 24) hospitals and completed baseline and all follow-up interviews. Data analysis for the present study was conducted from October 15, 2014, to June 6, 2016. Characteristics associated with loss of sexual activity were assessed using multinomial logistic regression analyses. Loss of sexual activity after AMI. Of the 2802 patients included in the analysis, 1889 were women (67.4%); median (25th-75th percentile) age was 49 (44-52) years (range, 18-55 years). At all time points, 637 (40.4%) of women and 437 (54.9%) of men were sexually active. Among people who were active at baseline, men were more likely than women to have resumed sexual activity by 1 month (448 [63.9%] vs 661 [54.5%]; P year (662 [94.4%] vs 1107 [91.3%]; P = .01) after AMI. Among people who were sexually active before and after AMI, women were less likely than men to report no sexual function problems in the year after the event (466 [40.3%] vs 382 [54.8%]; P year after the AMI. At 1 year, the most prevalent sexual problems were lack of interest (487 [39.6%]) and trouble lubricating (273 [22.3%]) among women and erectile difficulties (156 [21.7%]) and lack of interest (137 [18.8%]) among men. Those who had not communicated with a physician about sex in the first month after AMI were more likely to delay resuming sex (adjusted odds ratio [AOR], 1.51; 95% CI, 1.11-2.05; P = .008

    This report summarizes incidence rates of the five most commonly diagnosed sexually transmitted infections (STIs) among active component service members of the U.S. Armed Forces during 2000 to 2012. Human papillomavirus (HPV) infections were the most common, followed in decreasing order of frequency by infections associated with chlamydia, herpes simplex virus, gonorrhea, and syphilis. Compared to their counterparts, women, younger service members, soldiers, and enlisted members had higher incidence rates of each STI. Rates tended to be lower among married personnel. Rates of chlamydia, HPV, and gonorrhea diagnoses were notably higher among women during 2006 to 2008 but rates of the latter two infections have since declined sharply. The relatively recent introduction of STI screening among young service women and the HPV vaccine are discussed.

    Tubo-ovarian abscess (TOA) in non-sexually active female adolescents is a rare presentation to the pediatric emergency department. In the following case, bilateral TOA secondary to Streptococcus constellatus was diagnosed in a 13-year-old virginal female. The patient was seen 4 months before presentation for interventional radiology-guided drainage and antibiotic treatment for an intra-abdominal abscess due to suspected appendiceal rupture. Exploratory laparotomy on the most recent presentation demonstrated an appendix with inflammation and serositis on pathology report, a concern for chronic appendicitis with microperforation and subsequent bacterial translocation of the bilateral ovaries. This case report identifies a rare cause, pathogen, and the patient's demographics presenting with bilateral TOA. Most importantly, this case demonstrates the need for emergency medicine physicians to have a high index of suspicion for TOA in patients with a significant medical history of intra-abdominal pathology to promptly diagnose and treat high-morbidity pathology.

    A breast cancer (BC) diagnosis can profoundly affect the sex life of patient and partner within a couple. The purpose of the present study is to examine whether individual and partner sexual functioning, affectionate behavior, emotional closeness and depressive symptoms are associated with change over time in satisfaction with sex life of sexually active heterosexual couples dealing with BC and to explore whether the associations differ between patients and partners after adjustment for basic sociodemographic characteristics, comorbidity and BC treatment. Women with BC and their male partners participated in a longitudinal study (Time 1, ≤4 months after surgery; Time 2, 5 months later). Participants completed items from the PROMIS(®) Sexual Function and Satisfaction measure (version 1.0), two items measuring affectionate behavior, a single item measuring emotional closeness and the Center for Epidemiologic Studies-Depression Scale. Registers provided sociodemographic and medical information. Multilevel models were used, which take the interdependency of couples' scores into account. A total of 287 sexually active couples were included in the analyses. Less vaginal discomfort and more vaginal lubrication were associated with increases in patients' satisfaction with sex life. Patients' and partners' satisfaction increased with higher ratings of their own orgasm ability and of partners' timing of ejaculation. Patients' reports of affectionate behavior were positively associated with their partners' satisfaction, and vice versa for partners. Patients' satisfaction increased the more emotional closeness their partner experienced. Partners' depressive symptoms were negatively associated with their satisfaction. Sociodemographic factors and BC treatment were not significantly associated with change in satisfaction. Satisfaction with sex life in sexually active couples dealing with BC needs to be seen as a couple issue. Health professionals should take the partner into

    Current sexuality education programs vary widely in the accuracy of content, emphasis, and effectiveness. Data have shown that not all programs are equally effective for all ages, races and ethnicities, socioeconomic groups, and geographic areas. Studies have demonstrated that comprehensive sexuality education programs reduce the rates of sexual activity, sexual risk behaviors (eg, number of partners and unprotected intercourse), sexually transmitted infections, and adolescent pregnancy. One key component of an effective program is encouraging community-centered efforts. In addition to counseling and service provision to individual adolescent patients, obstetrician-gynecologists can serve parents and communities by supporting and assisting sexuality education. Because of their knowledge, experience, and awareness of a community's unique challenges, obstetrician-gynecologists can be an important resource for sexuality education programs.

    Full Text Available Chlamydia trachomatis is now one of the most prevalent bacteria found in classic sexually transmissible diseases (STD, and as such, constitutes a serious public health problem. We examined the prevalence of Chlamydia trachomatis, by polymerase chain reaction (PCR, in 121 sexually active women who sought treatment for STD in the Alfredo da Matta Institute of Dermatology and Venerology and the Institute of Tropical Medicine of Amazonas in Manaus, Brazil. These women were examined by a specific PCR for the chlamydial plasmid, and the nature of the amplicon was determined by restriction analysis and DNA sequencing. The PCR diagnosis revealed a prevalence of 20.7% infected women.

    2014-06-01

    This paper represents a case study of how social media activists have harnessed the power of Facebook, Twitter and mobile phone networks to address sexual harassment in Egypt. HarassMap plots reports of sexual harassment on a Google Map and informs victims of support services. Tahrir Bodyguard and Operation Anti-Sexual Harassment (OpAntiSH) protect female protestors who have been vulnerable to sexual aggression at the hands of unruly mobs and by agents of the state. Activists have access to an Android app called 'I'm Getting Arrested' or 'Byt2ebed 3alia' in Egyptian Arabic. The app sends the time and GPS coordinates of an arrest to family, fellow activists, legal counsel and social media outlets. The hope is the initiatives described in this paper could inspire public health ministries and activist NGOs to incorporate crowdsourcing social media applications in the spirit of health in all policies (HiAP). To that end, this paper will begin by defining social media activism from the perspective of the communications discipline. This paper will then demonstrate the significance of sexual harassment as a public health issue, and describe several social media efforts to document incidents and protect victims. The paper will conclude with discussion regarding how these innovations could be integrated into the HiAP approach. © The Author 2014. Published by Oxford University Press. All rights reserved.

    Teenage pregnancy is an important health and social problem in South Africa. So far research on adolescent sexual activity has been almost exclusively descriptive; as a result there is considerable knowledge about practices of adolescents in general and outcomes of their pregnancies, but very limited understanding of factors that place particular adolescents at increased risk of teenage pregnancy. Without this understanding, our ability to intervene effectively to reduce teenage pregnancy rates is limited. To undertake an exploratory study to investigate risk factors for teenage pregnancy among sexually active adolescents in an urban and peri-urban context. The study used a matched case-control design, with 191 cases and 353 age-matched controls from the same school or neighbourhood. Subjects were under 19 years of age and were recruited from township areas of Cape Town. A structured questionnaire was used to obtain information on socio-economic factors, contraceptive knowledge and use, and sexual behaviour. Conditional logistical regression was used to analyse the relationship between teenage pregnancy and the factors investigated. Teenage pregnancy was found to be most strongly associated with having frequent sex (risk ratio (RR) 30.81) without reliable contraceptive protection (RR 24.35), forced sexual initiation (RR 14.42), not owning a television set (RR 10.33), larger household size (RR 2.44), not living in a brick house (RR 5.09), not living with the biological father (RR 3.26), talking openly about sex with a boyfriend (RR 4.72), and perceiving most friends to be pregnant (RR 4.38). The findings suggest associations between the promotion of sexual health among adolescents and broader social development and promotion of gender equality. Although further research is needed, it is likely that important foci for short-term strategies should include developing assertiveness, enhancing decision-making competence, and promoting contraception and condoms as part of

  15. Effects of sex pheromones and sexual maturation on locomotor activity in female sea lamprey (Petromyzon marinus)

    Synchronization of male and female locomotor rhythmicity can play a vital role in ensuring reproductive success. Several physiological and environmental factors alter these locomotor rhythms. As sea lamprey, Petromyzon marinus, progress through their life cycle, their locomotor activity rhythm changes multiple times. The goal of this study was to elucidate the activity patterns of adult female sea lamprey during the sexual maturation process and discern the interactions of these patterns with exposure to male pheromones. During these stages, preovulated and ovulated adult females are exposed to sex pheromone compounds, which are released by spermiated males and attract ovulated females to the nest for spawning. The locomotor behavior of adult females was monitored in a natural stream with a passive integrated tag responder system as they matured, and they were exposed to a sex pheromone treatment (spermiated male washings) or a control (prespermiated male washings). Results showed that, dependent on the hour of day, male sex pheromone compounds reduce total activity (p pheromones modulate a locomotor rhythm in a vertebrate, and they suggest that the interaction between maturity stage and sex pheromone exposure contributes to the differential locomotor rhythms found in adult female sea lamprey. This phenomenon may contribute to the reproductive synchrony of mature adults, thus increasing reproductive success in this species.

    Frontotemporal dementia (FTD) is characterized by a number of prominent behavioral changes. While FTD has been associated with the presence of aberrant or unusual sexual behaviors in a proportion of patients, few studies have formally investigated changes in sexual function in this disease. We aimed to systematically quantify changes in sexual behavior, including current symptoms and changes from prior diagnoses, in behavioral-variant (bvFTD) and semantic dementia (SD), compared to Alzheimer's disease (AD). Carers of 49 dementia patients (21 bvFTD, 11 SD, 17 AD) were interviewed using the Sexual Behavior and Intimacy Questionnaire (SIQ), a survey designed to assess changes in sexual function across multiple domains including initiating, level of affection, and aberrant or unusual sexual behavior. BvFTD patients show prominent hyposexual behavior including decreased affection, initiation, and response to advances by partners, and decreased frequency of sexual relations, compared to AD and to SD patients. The greatest changes in sexual behavior compared to pre-diagnoses were found in the bvFTD group with a 90-100% decrease in initiation, response, and frequency of sexual relations. Notably, aberrant or unusual sexual behavior was reported in a minority of bvFTD and SD patients and occurred in patients who also showed hyposexual behavior toward their partner. Overall loss of affection, reduced initiation of sexual activity, and responsiveness is an overwhelming feature of bvFTD. In contrast, aberrant or unusual sexual behavior is observed in the minority of bvFTD patients. The underlying pathophysiology of these changes likely reflects structural and functional changes in frontoinsular and limbic regions including the hypothalamus.

    The physical conditions that determine whether or not solar active regions (ARs) produce strong flares and coronal mass ejections (CMEs) are not yet well understood. Here, we investigate the association between electric-current neutralization, magnetic shear along polarity inversion lines (PILs), and eruptive activity in four ARs: two emerging and two well-developed ones. We find that the CME-producing ARs are characterized by a strongly non-neutralized total current, while the total current in the ARs that did not produce CMEs is almost perfectly neutralized. The difference in the PIL shear between these two groups is much less pronounced, which suggests that the degree of current neutralization may serve as a better proxy for assessing the ability of ARs to produce CMEs.

  19. Orexin mediates initiation of sexual behavior in sexually naive male rats, but is not critical for sexual performance.

    The hypothalamic neuropeptide orexin mediates arousal, sleep, and naturally rewarding behaviors, including food intake. Male sexual behavior is altered by orexin receptor-1 agonists or antagonists, suggesting a role for orexin-A in this naturally rewarding behavior. However, the specific role of endogenous orexin-A or B in different elements of male sexual behavior is currently unclear. Therefore, the current studies utilized markers for neural activation and orexin cell-specific lesions to test the hypothesis that orexin is critical for sexual motivation and performance in male rats. First, cFos expression in orexin neurons was demonstrated following presentation of a receptive or non-receptive female without further activation by different elements of mating. Next, the functional role of orexin was tested utilizing orexin-B conjugated saporin, resulting in orexin cell body lesions in the hypothalamus. Lesions were conducted in sexually naive males and subsequent sexual behavior was recorded during four mating trials. Lesion males showed shortened latencies to mount and intromit during the first, but not subsequent mating trials, suggesting lesions facilitated initiation of sexual behavior in sexually naive, but not experienced males. Likewise, lesions did not affect sexual motivation in experienced males, determined by runway tests. Finally, elevated plus maze tests demonstrated reduced anxiety-like behaviors in lesioned males, supporting a role for orexin in anxiety associated with initial exposure to the female in naive animals. Overall, these findings show that orexin is not critical for male sexual performance or motivation, but may play a role in arousal and anxiety related to sexual behavior in naive animals.

    Mechanisms (i.e., thwarted belongingness, perceived burdensomeness, hopelessness) derived from the interpersonal theory of suicide which are hypothesized to account for the relation between sexual orientation self-concept ambiguity and active suicide ideation were examined. Participants included 349 women, among whom 42% currently self-ascribed a non-exclusively heterosexual sexual identity. Among women reporting higher levels of sexual self-concept ambiguity, greater risk for active suicide ideation is found when perceptions of burden and feelings of thwarted belonging co-occur with feelings of hopelessness. Results support relevant theory useful for understanding suicide risk among sexual minority women who acknowledge ambiguity with regard to their sexual orientation.

During consultations with these subjects, a physician conducted a semi-structured interview. Knowledge, attitudes and practices relating to sexual activity were evaluated. The comparison between the two groups was carried out using Student's t test, the chi-square test or Fisher's exact test. RESULTS: the two groups showed considerable similarities in terms of sexual behaviour, having engaged in the first sexual intercourse at the age of 15 and having had an average number of sexual partners of 1.5. Nevertheless, adolescents in the PG group had initiated sexual life earlier and tended to use less contraceptive methods during the first intercourse. Despite widespread knowledge of contraception, a large number of the adolescents did not use any contraceptive method during first sexual intercourse. In their current sexual life, an average of 81% of the participants referred to attaining orgasm. CONCLUSIONS: knowledge about contraceptive techniques is not enough to avoid unplanned pregnancies, suggesting the importance of investigating other psychosocial aspects of motherhood and maternal identity among teenagers.OBJETIVOS: investigar padrões de atividade sexual em adolescentes. MÉTODOS: estudo transversal realizado entre julho de 1998 e setembro de 2000, com 117 mulheres adolescentes sexualmente ativas oriundas de clínica privada, em Osasco, São Paulo, Brasil.

    This study investigated the possibility of an alternative to chemical medication in the treatment of sexual dysfunction in healthy women. The efficacy of a unique herbal formulation of Muira puama and Ginkgo biloba (Herbal vX) was assessed in 202 healthy women complaining of low sex drive. Various aspects of their sex life were rated before and after 1 month of treatment. Responses to self-assessment questionnaires showed significantly higher average total scores from baseline in 65% of the sample after taking the supplement. Statistically significant improvements occurred in frequency of sexual desires, sexual intercourse, and sexual fantasies, as well as in satisfaction with sex life, intensity of sexual desires, excitement of fantasies, ability to reach orgasm, and intensity of orgasm. Reported compliance and tolerability were good. These initial findings support the strong anecdotal evidence for the benefits of Herbal vX on the female sex drive. A double-blind study is planned to further research these results.

    2014-01-01

    We present a study of 7 large solar proton events (SPEs) of current solar cycle 24 (from 2009 January up to date). They were recorded by GOES spacecraft with highest proton fluxes over 200 pfu for energies $>$10 MeV. In situ particle measurements show that: (1) The profiles of the proton fluxes are highly dependent of the locations of their solar sources, namely flares or coronal mass ejections (CMEs); (2) The solar particle release (SPR) times fall in the decay phase of the flare emission, and are in accordance with the times when the CMEs travel to an average height of 7.9 solar radii; (3) The time differences between the SPR and the flare peak are also dependent of the locations of the solar active regions (ARs). The results tend to support the concept of proton acceleration by the CME-driven shock, even though there exists a possibility of particle acceleration at flare site with subsequent perpendicular diffusion of accelerated particles in the interplanetary magnetic field (IMF). We derive the integral ...

    Full Text Available In rodents, sexual behavior depends on the adequate detection of sexually relevant stimuli. The olfactory bulb (OB is a region of the adult mammalian brain undergoing constant cell renewal by continuous integration of new granular and periglomerular neurons in the accessory (AOB and main (MOB olfactory bulbs. The proliferation, migration, survival, maturation, and integration of these new cells to the OB depend on the stimulus that the subjects received. We have previously shown that 15 days after females control (paced the sexual interaction an increase in the number of cells is observed in the AOB. No changes are observed in the number of cells when females are not allowed to control the sexual interaction. In the present study we investigated if in male rats sexual behavior increases the number of new cells in the OB. Male rats were divided in five groups: 1 males that did not receive any sexual stimulation, 2 males that were exposed to female odors, 3 males that mated for 1 h and could not pace their sexual interaction, 4 males that paced their sexual interaction and ejaculated 1 time and 5 males that paced their sexual interaction and ejaculated 3 times. All males received three injections of the DNA synthesis marker bromodeoxyuridine at 1h intervals, starting 1h before the beginning of the behavioral test. Fifteen days later, males were sacrificed and the brains were processed to identify new cells and to evaluate if they differentiated into neurons. The number of newborn cells increased in the granular cell layer (also known as the internal cell layer of the AOB in males that ejaculated one or three times controlling (paced the rate of the sexual interaction. Some of these new cells were identified as neurons. In contrast, no significant differences were found in the mitral cell layer (also known as the external cell layer and glomerular cell layer of the AOB. In addition, no significant differences were found between groups in the MOB in

    Editors' Summary Background At the beginning of the AIDS epidemic, more men than women were infected with HIV, the virus that causes AIDS, but currently half of all HIV-positive adults are women. Most women become infected with HIV through unprotected sexual intercourse with an infected male partner. Biologically, women are twice as likely to become infected through unprotected heterosexual intercourse as men. Moreover, women are often unable to negotiate condom use because of unequal gender ...

  11. Estrogen Receptor β Activation Rapidly Modulates Male Sexual Motivation through the Transactivation of Metabotropic Glutamate Receptor 1a.

    In addition to the transcriptional activity of their liganded nuclear receptors, estrogens, such as estradiol (E2), modulate cell functions, and consequently physiology and behavior, within minutes through membrane-initiated events. The membrane-associated receptors (mERs) underlying the acute effects of estrogens on behavior have mostly been documented in females where active estrogens are thought to be of ovarian origin. We determined here, by acute intracerebroventricular injections of specific agonists and antagonists, the type(s) of mERs that modulate rapid effects of brain-derived estrogens on sexual motivation in male Japanese quail. Brain aromatase blockade acutely inhibited sexual motivation. Diarylpropionitrile (DPN), an estrogen receptor β (ERβ)-specific agonist, and to a lesser extent 17α-estradiol, possibly acting through ER-X, prevented this effect. In contrast, drugs targeting ERα (PPT and MPP), GPR30 (G1 and G15), and the Gq-mER (STX) did not affect sexual motivation. The mGluR1a antagonist LY367385 significantly inhibited sexual motivation but mGluR2/3 and mGluR5 antagonists were ineffective. LY367385 also blocked the behavioral restoration induced by E2 or DPN, providing functional evidence that ERβ interacts with metabotropic glutamate receptor 1a (mGluR1a) signaling to acutely regulate male sexual motivation. Together these results show that ERβ plays a key role in sexual behavior regulation and the recently uncovered cooperation between mERs and mGluRs is functional in males where it mediates the acute effects of estrogens produced centrally in response to social stimuli. The presence of an ER-mGluR interaction in birds suggests that this mechanism emerged relatively early in vertebrate history and is well conserved. Significance statement: The membrane-associated receptors underlying the acute effects of estrogens on behavior have mostly been documented in females, where active estrogens are thought to be of ovarian origin.

    Research indicates that adolescents in low-income countries have an early sexual debut and engage in risky sexual behaviours. Few studies in low-income countries however, have explored the factors that influence young people's sexual behaviours. This study examined individual, family and peer-level factors associated with premarital sexual behaviours in the Lao People's Democratic Republic (PDR). A cross-sectional survey was undertaken with unmarried youth aged 18 to 24 years (N = 1200) in Vientiane Capital City. Logistic regression models, controlling for confounding variables, were employed to test for the contribution of factors influencing premarital sexual activity. Most respondents held positive attitudes towards premarital sex, with males having more liberal attitudes than females (mean score of 2.68 vs. 2.32, p sexual activity was higher among males than females (44.7% and 19.2%, respectively). Predictors of premarital sex for males were age, sexual attitudes, perceived parental expectations regarding sex, dating and peer influence. For females, predictors were father's level of education, parent-youth sexual communication, peer influence and liberal sexual attitudes. The results highlight the role of parent-youth interaction and peer influence. The results suggest the need for a range of strategies at the individual, peer and family level, as well as a gender-specific focus.

    High risk human papillomavirus (hr-HPV) infection and the dual burden of HIV remains a huge challenge in some low-income countries (LICs) such as Swaziland with limited or no data. We estimated the prevalence and investigated determinants of hr-HPV, including HIV infection among sexually active women in Swaziland. A total of 655 women aged between 15 and 49 years from five health facilities were randomly enrolled using a cross-sectional study design. Cervical cells were tested for hr-HPV types using GeneXpert HPV Assays. The overall weighted hr-HPV prevalence was 46.2% (95%CI: 42.8-49.5). Of hr-HPV infected women, 12.4% (95%CI: 8.6-17.5) were HPV16-positive, 13.8% (95%CI:12.0-15.8) were positive for HPV18/45, 26.7% (95%CI: 24.2-29.3) for HPV31/33/35/52/58, 7.6% (95%CI: 7.6-11.9) for HPV51/59 and 11.0%, (95%CI: 7.9-15.3) for HPV39/56/66/68. Prevalence of hr-HPV decreased with increasing age. Overall HIV prevalence remained high (42.7%; 95%CI: 35.7-46.2). HIV infection was associated with hr-HPV infection (Adjusted OR = 4.9, 95%CI: 3.043-7.8, p<0.001). Overall hr-HPV/HIV co-infection was 24.4% (95%CI: 20.3-29.1) which was significantly higher among younger age groups (p<0.001). Prevalence of multiple group hr-HPV infection was significantly higher in HIV-positive versus -negative women (27.7% and 12.7% respectively, p<0.001). The presence, absence or unknown of history of STI with HIV did not appear to modify the relationship with hr-HPV (OR = 4.2, 95%CI: 2.6-7.1, OR = 4.6, 95%CI: 2.8-7.7, p<0.001, p<0.001 and OR = 4.1, 95%CI: 1.3-13.4, p<0.021 respectively). The prevalence of hr-HPV infection was high and significantly associated with HIV among sexually active women. Furthermore, the study has provided essential information about the HIV link with hr-HPV infections which may explain the high prevalence among HIV infected women. This can contribute to policy development and planning of prevention strategies incorporating HPV infection prevention especially among

    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.

    Full Text Available This paper presents improvement of a harmonics extraction algorithm, known as the fundamental active current (FAC adaptive linear element (ADALINE neural network with the integration of photovoltaic (PV to shunt active power filters (SAPFs as active current source. Active PV injection in SAPFs should reduce dependency on grid supply current to supply the system. In addition, with a better and faster harmonics extraction algorithm, the SAPF should perform well, especially under dynamic PV and load conditions. The role of the actual injection current from SAPF after connecting PVs will be evaluated, and the better effect of using FAC ADALINE will be confirmed. The proposed SAPF was simulated and evaluated in MATLAB/Simulink first. Then, an experimental laboratory prototype was also developed to be tested with a PV simulator (CHROMA 62100H-600S, and the algorithm was implemented using a TMS320F28335 Digital Signal Processor (DSP. From simulation and experimental results, significant improvements in terms of total harmonic distortion (THD, time response and reduction of source power from grid have successfully been verified and achieved.

    Sexuality and sexual disorders of patients with psychoses are frequently neglected and under-investigated. The main purpose of the present study is to discuss the subjective experience of sexuality in patients with psychosis within the general psychodynamic and phenomenological understandings of psychotic states. The authors, both psychotherapists, dealing with patients with psychoses, reflected experiences from their clinical work with the help of the conceptual frameworks of psychodynamic and phenomenological psychiatry. Willingness and need of patients to talk about sexuality, non-specificity of frequencies and variety of sexual disorders in psychotic patients, difficulties in establishment of a stable (sexual) identity and the question of homosexuality, absence of sexual activities with others and feelings of guilt and inadequacy, masturbation with its functions, impulsive sexual acts or lack of sexual self-control, erotic delusions and erotic transference were the main findings, dominating the sexual sphere of these patients. All these manifestations of sexuality in patients with psychosis can be seen - as exposed in discussion - as consequences of a basic self-disorder (phenomenological perspective) or of difficulties in regulating closeness and distance (psychodynamic perspective). Reasons of avoidance of treatment of sexuality by the therapists of psychotic patients are discussed as well. Implications for dealing with sexuality issues in psychotherapy of patients with psychoses were drawn from the above findings in the last part of the article.

    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.

Questions concerned sociodemographic information; family characteristics; personal activities; knowledge and attitudes regarding sexuality; sexual experience; and contraceptive use. Knowledge related to sexuality was limited. Males tended to mainly discuss sexuality with their male peers (49.8%. Attitudes towards sexual activity and condom use were largely positive, although some males expressed ambivalent feelings towards the latter. Of the sample, 43% had ever had sex; age at first sexual intercourse was 13 years. While 88% of the sample would use condoms, 74% also gave reasons for not using them. Sexual activity was related to age, ever having repeated a grade, living with only one parent or in a mixed family, activities such as going to parties, use of alcohol, tobacco, and drugs, and viewing pornographic videos or magazines. Many male adolescents were at risk of causing an unintended pregnancy or acquiring an STD.Con el objetivo de documentar el nivel de conocimiento y las actitudes con respecto a sexualidad y las prácticas sexuales de los adolescentes varones de colegios secundarios en Lima, Peru, 991 estudiantes varones, entre los 12-19 años, completaron una encuesta autoaplicable y anónima dentro de un Programa de Prevención de Comportamientos Sexuales de Riesgo.

    2010-01-01

    The hypothalamic neuropeptide orexin mediates arousal, sleep, and naturally rewarding behaviors, including food intake. Male sexual behavior is altered by orexin receptor-1 agonists or antagonists, suggesting a role for orexin-A in this naturally rewarding behavior. However, the specific role of endogenous orexin-A or B in different elements of male sexual behavior is currently unclear. Therefore, the current studies utilized markers for neural activation and orexin cell-specific lesions to t...

    Studies of heterosexual populations across the globe and men who have sex with men (MSM) in a few developed countries showed that earlier sexual debut (sexarche) was associated with higher levels of co-occurring and subsequent HIV risk behaviors. We examined the relationships between earlier anal sexarche, unprotected earlier anal sexarche and current HIV risks among MSM from Asia. A cross-sectional online survey was conducted among MSM (N = 10,826) in Asia in 2010. Bivariate and multivariable logistic regressions were used to identify co-occurring (i.e., sexual experiences during sexarche) and current HIV-related risk factors (i.e., past 6 months) associated with earlier anal sexarche (before the age of 18) and unprotected earlier anal sexarche, respectively. Earlier anal sexarche was significantly associated with lack of condom use, being anal receptive or both receptive and insertive, and having a partner who were older during sexarche. It was also associated with current HIV-related risk behaviors including having multiple male sexual partners, having been paid for sex, and increased frequencies of recreational drug use. Unprotected earlier anal sexarche was significantly associated with inconsistent condom use in the past the 6 months. Improved and culturally sensitive sex education at schools should be included in national and regional HIV/AIDS prevention programming and policies in Asia. Such sex education programs should incorporate curriculum that address sexuality, sexual orientation, and sexual behaviors beyond those related to reproductive health.

    More than a quarter of women who experience acute cystitis develop recurrence but information on specific urovirulent genetic profile of uropathogenic Escherichia coli associated with recurrent cystitis is still limited. In this prospective cohort study, index episode E. coli from a cohort of 46 sexually active women with acute cystitis who reported recurrence during followup were grouped into repeat infection (RI) and single infection (SI) isolates, based on enterobacterial repetitive intergenic consensus (ERIC) PCR profile comparison with subsequent E. coli isolated from same women. PCR for phylogrouping and 15 virulence genes along with test for biofilm formation were done. Virulence score was calculated for each isolate as number of virulence genes detected. Among 46 index E. coli, 22 were RI, and 24 were SI isolates. RI isolates had phylogroup B2 as majority (54.5%) which is typically described as more virulent phylogroup and virulence score for RI isolates was also significantly higher compared to SI isolates. Virulence gene malX (p = 0.03) was significantly associated with RI isolates. 68.2% RI isolates were strong to moderate biofilm producers in comparison to 33.3% SI isolates, an important survival strategy to reside in bladder and or vagina. Overall, E. coli associated with recurrent cystitis appear to be more virulent and malX seems to have a role in causing repeat infection. Copyright © 2014 Elsevier Ltd. All rights reserved.

    This descriptive study assessed maternal attitudes to youth-related activities in Delta State. Using an adapted questionnaire, 300 women with adolescent children were chosen through a multistage sampling technique and relevant data obtained regarding their socio-economic status, perceptions and values as well as their knowledge of basic reproductive health concerns. Most of the women interviewed (95%), believed it was very important that young people completed secondary education and another 72% said they would normally set rules in their homes regarding what young people should read or watch. Sixty-seven percent of those studied, discussed sexuality issues regularly with their adolescent children, though only 46.4% of them were comfortable discussing these issue and about 50% admitted having enough information in such discussions. Another 76% of the women would approve of their children receiving reproductive health information and service including contraceptive condoms. The mothers studied believed that guided reproductive health information and services should be routinely provided for young people. The findings strongly suggest that the mothers who are important stakeholders in Adolescent Health would most likely be supportive of youth programmes. Most of the findings differ from those of other studies, and a qualitative study would be carried out to identify the reasons for these interesting findings.

    To investigate the difference in the brain activation patterns of males and females during video sexual stimulation by functional magnetic resonance imaging (fMRI). The participants were 20 adult males and 20 adult females, all healthy, right-handed, and with no history of sexual function disorder and physical, psychiatric or neurological diseases. Blood-oxygen-level-dependent fMRI was performed using a 1.5 T MR scanner. Three-dimensional anatomical image of the entire brain were obtained by using a T1-weighted three-dimensional anatomical image spoiled gradient echo pulse sequence. Each person was shown neutral and erotic video sequences for 60 s each in a block-study fashion, i.e. neutral scenes--erotic scenes--neutral scenes, and so on. The total scanning time was approximately 7 minutes, with a 12 s interval between two subsequent video sequences in order to avoid any overlapping between erotic and neutral information. The video sexual stimulation produced different results in the men and women. The females showed activation both in the left and the right amygdala, greater in the former than in the latter ([220.52 +/- 17.09] mm3 vs. [155.45 +/- 18.34] mm3, P < 0.05), but in the males only the left amygdala was activated. The males showed greater brain activation than the females in the left anterior cingulate gyrus ([420.75 +/- 19.37] mm3 vs. [310.67 +/- 10.53] mm3, P < 0.05), but less than the females in the splenium of the corpus callosum ([363.32 +/- 13.30] mm3 vs. [473.45 +/- 14.92] mm3, P < 0.01). Brain activation patterns of males and females during video sexual stimulation are different, underlying which is presumably the difference in both the structure and function of the brain between men and women.

    During paroxysmal neocortical oscillations, sudden depolarization leading to the next cycle occurs when the majority of cortical neurons are hyperpolarized. Both the Ca2+-dependent K+ currents (IK(Ca)) and disfacilitation play critical roles in the generation of hyperpolarizing potentials. In vivo experiments and computational models are used here to investigate whether the hyperpolarization-activated depolarizing current (Ih) in cortical neurons also contributes to the generation of paroxysmal onsets. Hyperpolarizing current pulses revealed a depolarizing sag in ≈20% of cortical neurons. Intracellular recordings from glial cells indirectly indicated an increase in extracellular potassium concentration ([K+]o) during paroxysmal activities, leading to a positive shift in the reversal potential of K+-mediated currents, including Ih. In the paroxysmal neocortex, ≈20% of neurons show repolarizing potentials originating from hyperpolarizations associated with depth-electroencephalogram positive waves of spike-wave complexes. The onset of these repolarizing potentials corresponds to maximal [K+]o as estimated from dual simultaneous impalements from neurons and glial cells. Computational models showed how, after the increased [K+]o, the interplay between Ih, IK(Ca), and a persistent Na+ current, INa(P), could organize paroxysmal oscillations at a frequency of 2–3 Hz.

  10. Westermarck, Freud, and the incest taboo: does familial resemblance activate sexual attraction?

    Science.gov (United States)

    Fraley, R Chris; Marks, Michael J

    2010-09-01

    Evolutionary psychological theories assume that sexual aversions toward kin are triggered by a nonconscious mechanism that estimates the genetic relatedness between self and other. This article presents an alternative perspective that assumes that incest avoidance arises from consciously acknowledged taboos and that when awareness of the relationship between self and other is bypassed, people find individuals who resemble their kin more sexually appealing. Three experiments demonstrate that people find others more sexually attractive if they have just been subliminally exposed to an image of their opposite-sex parent (Experiment 1) or if the face being rated is a composite image based on the self (Experiment 2). This finding is reversed when people are aware of the implied genetic relationship (Experiment 3). These findings have implications for a century-old debate between E. Westermarck and S. Freud, as well as contemporary research on evolution, mate choice, and sexual imprinting.

    We propose the use of a combination of ultrasonic and magnetic fields in conductive media for the creation of RF electrical current via the Lorentz force, in order to achieve current generation with extreme sub-wavelength resolution at large depth. We demonstrate the modeling, generation, and measurement of Lorentz current in a conductive solution and show that this current can be localized at a distance of 13 cm from the ultrasonic source to a region about three orders of magnitude smaller than the corresponding wavelength of electromagnetic waves at the same operation frequency. Our results exhibit greater depth, tighter localization, and closer agreement with prediction than previous work on the measurement of Lorentz current in a solution of homogeneous conductivity. The proposed method of RF current excitation overcomes the trade-off between focusing and propagation that is fundamental in the use of RF electromagnetic excitation alone and has the potential to improve localization and depth of operation for RF current-based biomedical applications.

    We examined sexual orientation disparities in cancer-related risk behaviors among adolescents. We pooled data from the 2005 and 2007 Youth Risk Behavior Surveys. We classified youths with any same-sex orientation as sexual minority and the remainder as heterosexual. We compared the groups on risk behaviors and stratified by gender, age ( 14 years), and race/ethnicity. Sexual minorities (7.6% of the sample) reported more risk behaviors than heterosexuals for all 12 behaviors (mean = 5.3 vs 3.8; P sexual orientation disparities in analyses by gender, followed by age, and then race/ethnicity; they persisted in analyses by gender, age, and race/ethnicity, although findings were nuanced. Data on cancer risk, morbidity, and mortality by sexual orientation are needed to track the potential but unknown burden of cancer among sexual minorities.

    Parents have the potential to protect against adolescent sexual risk, including early sexual behavior, inconsistent condom use, and outcomes such as pregnancy and sexually transmitted infections (STIs). Identification of the specific parenting dimensions associated with sexual risk in adolescence and young adulthood is necessary to inform and focus prevention efforts. The current study examined the relation of proximal (e.g., discussions of sexual costs) and distal (e.g., parental involvement, relationship quality) parenting variables with concurrent and longitudinal adolescent sexual behavior. The National Longitudinal Study of Adolescent Health (Add Health) provided a nationally representative sample with information about the family using adolescent and parent informants. Longitudinal information about sexual risk included adolescent condom use and adolescent sexual initiation, as well as young adult unintended pregnancy, reports of STIs, and biological assay results for three STIs. Higher parent-adolescent relationship quality was associated with lower levels of adolescent unprotected intercourse and intercourse initiation. Better relationship quality was also associated with lower levels of young adult STIs, even when accounting for prior sexual activity. Unexpectedly, more parent reports of communication regarding the risks associated with sexual activity were negatively associated with condom use and greater likelihood of sexual initiation. These results demonstrate that parents play an important role, both positive and negative, in sexual behavior, which extends to young adulthood, and underscores the value of family interventions in sexual risk prevention.

    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.

    Active surveillance has been increasingly utilized as a strategy for the management of favorable-risk, localized prostate cancer. In this review, we describe contemporary management strategies of active surveillance, with a focus on traditional stratification schemes, new prognostic tools, and patient outcomes. Patient selection, follow-up strategy, and indication for delayed intervention for active surveillance remain centered around PSA, digital rectal exam, and biopsy findings. Novel tools which include imaging, biomarkers, and genetic assays have been investigated as potential prognostic adjuncts; however, their role in active surveillance remains institutionally dependent. Although 30-50% of patients on active surveillance ultimately undergo delayed treatment, the vast majority will remain free of metastasis with a low risk of dying from prostate cancer. The optimal method for patient selection into active surveillance is unknown; however, cancer-specific mortality rates remain excellent. New prognostication tools are promising, and long-term prospective, randomized data regarding their use in active surveillance will be beneficial.

    AIM: To obtain current data about child sexual abuse in Denmark and to assess abused children's own perception of early sexual experiences, which are unlawful according to the Danish Penal Code. METHODS: Multimedia computer-based self-administered questionnaires (CASI) were completed by a national...... representative sample of 15-16-y-olds. Child sexual abuse was defined according to the penal code and measured by questions defining specific sexual activities, the relationship between the older person and the child, and the youth's own perception of the incident. RESULTS: Among 5829 respondents, 11% reported...... unlawful sexual experiences, 7% of boys and 16% of girls. Only 1% of boys and 4% of girls felt that they "definitely" or "maybe" had been sexually abused. CONCLUSION: A relatively high percentage of Danish adolescents have early, unlawful sexual experiences. However, young people's own perception of sexual...

    The absence of the father in the resident home is an increasing trend in the United States, and the belief that the absence of fathers is lined with a variety of social pathologies is gaining national momentum. This study explored the relationship of father absence on self-esteem and self-reported sexual activity among rural southern adolescents. A sample of 1,409 adolescents (558 males and 851 females) aged 11 to 18 years was surveyed, and the Miller Self-Esteem Questionnaire (MSQ) was used to measure self-esteem. Analysis revealed that increased sexual activity occurred by adolescents in homes where no father present in the residence. Although a statistical significance was noted in the relationship between father absence and lower self-esteem, the magnitude of the difference was not large. Further, no relationship between self-esteem and sexual activity was noted. Seemingly, the absence of the father has a potentially detrimental effect on adolescents' lifestyle choices. Consideration of the notion that the phenomena of fathering rather than the mere presence of a father may contribute to differences in adolescent's lifestyle choices should be studied.

    This article describes three studies in which we explored the influence of the sexist ideology attributed to the perpetrator on women's responses to hypothetical acts of sexual assault perpetrated by male intimate partners. In Study 1 (n = 83), college women read three sexual assault scenarios in the context of an intimate relationship. The male partner's sexist ideology (benevolent, hostile, or control) was manipulated within participants. Women showed less active responses when the partner had been described as a benevolent sexist man. This effect was replicated in Study 2 (n = 103), which showed a relationship between women's less active responses and the belief that benevolent sexist men are very attracted to and interested in their partners. Study 3 (n = 130) demonstrated experimentally that women's responses are less active when they are exposed to information that indicates that the perpetrator is both high in benevolent sexism and highly attracted to his victim than when the latter information is not provided. Results suggest that sexist ideology and particularly benevolent sexism-attributed to the perpetrator in this case-is highly important in women's reactions to acts of sexual violence perpetrated by male intimate partners.

    Sexuality is still a taboo in Middle Eastern countries, and Lebanon is no exception. This study's objective was to evaluate attitudes towards sexuality and its practice among university students in Lebanon and assess their respective correlates. The cross-sectional study was carried out among students selected from seventeen universities across Lebanon. The participants received a self-administered standardized questionnaire that assessed their attitudes towards sexuality. It included questions on socio-demographic factors, risk-taking, risky behaviours and sexuality-related questions. Among 3384 students, 2700 (79.8%) answered the questions on sexuality. Around 15% had engaged in sexual activity, while 20% were regularly sexually active. Among males, 34.8% had never had sexual activity, 29.9% had tried it and 35.3% were regularly sexually active. Among females the results were respectively 85.1%, 5.3% and 9.6% (p<0.001). Only 36% regularly used condoms during their relationships. A liberal attitude towards sex, male sex, motives for risky behaviours, current cigarette smoking and problematic alcohol consumption were associated with sexual activity. Realizing that risky behaviours are dangerous, health concerns related to sexual relationships and a liberal attitude towards sex were associated with regular condom use. However, being bothered by condoms and female sex were inversely associated with condom use. Finally, participants who had motives for, and those who felt excited about risky behaviours, and those reporting current cigarette and waterpipe smoking and problematic alcohol consumption (β=0.600; p=0.002) embraced a more liberal attitude towards sex. Conversely, females (β=-7.58; p<0.001) and individuals who considered risky behaviours as dangerous reported an unfavourable attitude towards sexuality. A substantial proportion of Lebanese university students have regular sexual activity, but a low percentage use condoms for protection. Interventions are

    Musth in male African elephants, Loxodonta africana, is associated with increased aggressive behavior, continuous discharge of urine, copious secretions from the swollen temporal glands, and elevated androgen levels. During musth, bulls actively seek out and are preferred by estrous females although sexual activity is not restricted to the musth condition. The present study combines recently established methods of fecal hormone analysis with long-term observations on male-female associations as well as the presence and intensity of physical signals to provide a more detailed picture about the physical, physiological, and behavioral characteristics of different states of sexual activity in free-ranging African elephants. Based on quantitative shifts in individual bull association patterns, the presence of different physical signals, and significant differences in androgen levels, a total of three potential sub-categories for sexually active bulls could be established. The results demonstrate that elevations in androgen levels are only observed in sexually active animals showing temporal gland secretion and/or urine dribbling, but are not related to the age of the individual. Further, none of the sexually active states showed elevated glucocorticoid output indicating that musth does not represent an HPA-mediated stress condition. On the basis of these results, we suggest that the term "musth" should be exclusively used for the competitive state in sexually active male elephants and that the presence of urine dribbling should be the physical signal used for defining this state.

    Content analyses have cataloged the sexual scripts present in magazines largely because of their perceived value to readers and their potential role as sex educators. Although it is generally agreed that magazines have the potential to influence sexual attitudes and behavioral intentions, the effects of this medium are not as frequently researched as are other forms of media. The current study tested whether exposure to magazines was associated with intentions related to sexual consent negotiation. A survey of 313 college students indicated that exposure to men's magazines was significantly associated with lower intentions to seek sexual consent and lower intentions to adhere to decisions about sexual consent. In contrast, exposure to women's magazines was significantly associated with greater intentions to refuse unwanted sexual activity. Overall, the findings of this study further reinforce the critical need for responsible and realistic portrayals of sex in entertainment media, specifically magazines.

    Interviews with 81 traditional healers from 4 Copperbelt towns in Zambia (Chililabombwe, Chingola, Luanshya, and Mufulira) investigated healers' understanding of, attitudes toward, and management of sexually transmitted diseases (STDs). In general, Zambian traditional healers had detailed constructs of the physiology and infective processes underlying syphilis, gonorrhea, chancroid, and AIDS. STDs were considered to be caused by "dirt" or contamination residing in sperm or vaginal fluids and were closely linked to violations of moral codes. Healers shared complex nosologies based on distinctions between symptoms of different STD pathologies that were more inclusive than biomedical categories. Although condom use was not promoted, healers understood the importance of preventing an infective agent from passing from one person to another. Except for AIDS, STDs were considered curable by expelling the dirt through purgatives or emetics. Modern medicine was perceived as treating only STD symptoms, not curing. Most traditional healers insisted that the infected partner bring the other partner for consultation or treatment was withheld. Since these findings identified some areas of compatibility between indigenous and biomedical models of STDs, the Traditional Medicine Unit of the Ministry of Health and the HIV/AIDS Prevention Project of the Morehouse School of Medicine (Lusaka) established a program in which traditional healers receive AIDS training and learn to counsel clients on safer sex behaviors. Follow-up entails monthly meetings between health professionals and traditional healers. Since program initiation in June 1994, 800 traditional healers and 70 health professionals have participated. Traditional healers now sell condoms to their clients through a social marketing program.

    Anxiety and depression are considered as stress-related disorders, which present considerable sex differentiation. In animal models of anxiety and depression sex differences have been described and linked to the sexually dimorphic hypothalamus-pituitary-adrenals (HPA) axis. The present study aimed to adjust corticosterone, the main HPA axis stress hormone, in male and female adrenalectomized rats with oral (25 μg/ml) corticosterone replacement (ADXR). Subsequently we investigated the behavioral performance of ADXR rats in the open field, light/dark and forced swim test (FST). Male ADXR rats showed less anxiety-like behavior when compared to sham-operated controls, despite adequate corticosterone replacement. They further showed increased swimming and reduced climbing behavior in the FST, while immobility duration did not differ from sham-operated males. On the contrary, adrenalectomy and corticosterone replacement did not have significant effects on the female behavioral response. Females were generally more active and presented less anxiety-like behavior than males, while they exhibited higher depressive-like symptomatology in the FST. ADXR affected behavioral responses predominantly in males, which in turn modified sex differences in the behavioral profile. Females in proestrous and estrous did not differ from females in diestrous and methestrous in any measured behavioral response. Present results suggest that the male and not the female behavioral responses in models of anxiety and depression were mainly affected by ADXR. These findings may play a significant role in explaining the differential coping strategy of the two sexes in response to stressful experiences.

    Background High risk human papillomavirus (hr-HPV) infection and the dual burden of HIV remains a huge challenge in some low-income countries (LICs) such as Swaziland with limited or no data. We estimated the prevalence and investigated determinants of hr-HPV, including HIV infection among sexually active women in Swaziland. Methods A total of 655 women aged between 15 and 49 years from five health facilities were randomly enrolled using a cross-sectional study design. Cervical cells were tested for hr-HPV types using GeneXpert HPV Assays. Results The overall weighted hr-HPV prevalence was 46.2% (95%CI: 42.8–49.5). Of hr-HPV infected women, 12.4% (95%CI: 8.6–17.5) were HPV16-positive, 13.8% (95%CI:12.0–15.8) were positive for HPV18/45, 26.7% (95%CI: 24.2–29.3) for HPV31/33/35/52/58, 7.6% (95%CI: 7.6–11.9) for HPV51/59 and 11.0%, (95%CI: 7.9–15.3) for HPV39/56/66/68. Prevalence of hr-HPV decreased with increasing age. Overall HIV prevalence remained high (42.7%; 95%CI: 35.7–46.2).

    Epoxyeicosatrienoic acids (EETs) are cardioprotective mediators metabolized by soluble epoxide hydrolase (sEH) to form corresponding diols (DHETs). As a sex-susceptible target, sEH is involved in the sexually dimorphic regulation of cardiovascular function. Thus, we hypothesized that the female sex favors EET-mediated potentiation of cardiac function via downregulation of sEH expression, followed by upregulation of peroxisome proliferator-activated receptors (PPARs). Hearts were isolated from male (M) and female (F) wild-type (WT) and sEH-KO mice, and perfused with constant flow at different preloads. Basal coronary flow required to maintain the perfusion pressure at 100 mmHg was significantly greater in females than males, and sEH-KO than WT mice. All hearts displayed a dose-dependent decrease in coronary resistance and increase in cardiac contractility, represented as developed tension in response to increases in preload. These responses were also significantly greater in females than males, and sEH-KO than WT 14,15-EEZE abolished the sex-induced (F vs. M) and transgenic model-dependent (KO vs. WT) differences in the cardiac contractility, confirming an EET-driven response. Compared with M-WT controls, F-WT hearts expressed downregulation of sEH, associated with increased EETs and reduced DHETs, a pattern comparable to that observed in sEH-KO hearts. Coincidentally, F-WT and sEH-KO hearts exhibited increased PPARα expression, but comparable expression of eNOS, PPARβ, and EET synthases. In conclusion, female-specific downregulation of sEH initiates an EET-dependent adaptation of cardiac function, characterized by increased coronary flow via reduction in vascular resistance, and promotion of cardiac contractility, a response that could be further intensified by PPARα. © 2016 The Authors.

    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.

  15. How has early testicular cancer affected your life? A study of sexual function in men attending active surveillance for stage one testicular cancer.

    2015-06-01

    Testicular cancer is the most common cancer in young men, it is frequently diagnosed at key times in relationship formation. In early stage disease the vast majority of tumours will be cured by surgery alone with patients being offered active surveillance rather than adjuvant therapies. To date, research has not evaluated how surveillance alone impacts on sexual function. The aim of this quantitative longitudinal study was to ascertain the sexual function of men with stage one disease at 3 and 12 months post diagnosis and to compare with normative data. Additional data was collected on the information men sought regarding sexual function and media they used to access this. This study shows that men's sexual function is altered at diagnosis and improves by 3 months. At 12 months, whilst not statistically significant, sexual function improves but not to the same level as normative data comparison. Men appear to find verbal information useful at 3 months, however men appear to be seeking written and online information at 12 months. The intricacies of sexual function together with the low number of participants may have been best met with a qualitative approach. However, the information data indicates the importance of further research into the effects of early stage testicular cancer on sexual function. Therefore, further qualitative research is recommended to explore the effects of early stage testicular cancer in relation to sexual function. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Adolescent health is a growing concern. High rates of binge drinking and teenage pregnancies, documented in the UK, are two measures defining poor wellbeing. Improving wellbeing through schools is a priority but information on the impact of wellbeing on alcohol use, and on sexual activity among schoolchildren is limited. Methods A cross-sectional survey using self-completed questionnaires was conducted among 3,641 schoolchildren aged 11-14 years due to participate in a sex and relationships education pilot programme in 15 high schools in North West England. Bivariate and multivariate analyses were conducted to examine the relationship between wellbeing and alcohol use, and wellbeing and sexual activity. Results A third of 11 year olds, rising to two-thirds of 14 year olds, had drunk alcohol. Children with positive school wellbeing had lower odds of ever drinking alcohol, drinking often, engaging in any sexual activity, and of having sex. General wellbeing had a smaller effect. The strength of the association between alcohol use and the prevalence of sexual activity in 13-14 year olds, increased incrementally with the higher frequency of alcohol use. Children drinking once a week or more had 12-fold higher odds of any sexual activity, and 10-fold higher odds of having sex. Rare and occasional drinkers had a significantly higher odds compared with non-drinkers. Conclusions The relationship between wellbeing and alcohol use, and wellbeing and sexual activity reinforces the importance of initiatives that enhance positive wellbeing in schoolchildren. The association between alcohol use and sexual activity highlights the need for integrated public health programmes. Policies restricting alcohol use may help reduce sexual exposure among young teenagers.

    Lesbian and bisexual women's sexual health is neglected in much Government policy and practice in England and Wales. This paper examines lesbian and bisexual women's negotiation of sexual health, drawing on findings from a small research project. Themes explored include invisibility and lack of information, influences on decision-making and sexual activities and experiences of services and barriers to sexual healthcare. Key issues of importance in this respect are homophobic and heterosexist social contexts. Drawing on understandings of lesbian, gay and bisexual human rights, sexual rights and sexual citizenship, it is argued that these are useful lenses through which to examine and address lesbian and bisexual women's sexual health and related inequalities.

    Though research indicates a complex link between substance use and sexual risk behavior, there is limited research on the association between sexual risk behavior and prescription drug misuse. In light of alarming increases in prescription drug misuse and the role of demographic characteristics in sexual risk behavior and outcomes, the current study examined demographic differences (gender, sexual identity, age, relationship status, parental class background, and race/ethnicity) in sexual risk behavior, sexual behavior under the influence of prescription drugs, and sexual risk behavior under the influence of prescription drugs in a sample of 402 young adults (ages 18 to 29) who misused prescription drugs. Nearly half of the sexually active young adult prescription drug misusers in this sample reported recent sex under the influence of prescription drugs; more than three-quarters reported recent sex without a condom; and more than one-third reported recent sex without a condom after using prescription drugs. Zero-inflated Poisson regression models indicated that White race, younger age, higher parental class, and being a heterosexual man were all associated with sexual risk behavior, sex under the influence of prescription drugs, and sexual risk under the influence of prescription drugs. Findings have implications for the targeting of prevention and intervention efforts.

  1. Hmgcr in the corpus allatum controls sexual dimorphism of locomotor activity and body size via the insulin pathway in Drosophila.

    Directory of Open Access Journals (Sweden)

    Yesser Hadj Belgacem

    Full Text Available The insulin signaling pathway has been implicated in several physiological and developmental processes. In mammals, it controls expression of 3-Hydroxy-3-Methylglutaryl CoA Reductase (HMGCR, a key enzyme in cholesterol biosynthesis. In insects, which can not synthesize cholesterol de novo, the HMGCR is implicated in the biosynthesis of juvenile hormone (JH. However, the link between the insulin pathway and JH has not been established. In Drosophila, mutations in the insulin receptor (InR decrease the rate of JH synthesis. It is also known that both the insulin pathway and JH play a role in the control of sexual dimorphism in locomotor activity. In studies here, to demonstrate that the insulin pathway and HMGCR are functionally linked in Drosophila, we first show that hmgcr mutation also disrupts the sexual dimorphism. Similarly to the InR, HMGCR is expressed in the corpus allatum (ca, which is the gland where JH biosynthesis occurs. Two p[hmgcr-GAL4] lines were therefore generated where RNAi was targeted specifically against the HMGCR or the InR in the ca. We found that RNAi-HMGCR blocked HMGCR expression, while the RNAi-InR blocked both InR and HMGCR expression. Each RNAi caused disruption of sexual dimorphism and produced dwarf flies at specific rearing temperatures. These results provide evidence: (i that HMGCR expression is controlled by the InR and (ii that InR and HMGCR specifically in the ca, are involved in the control of body size and sexual dimorphism of locomotor activity.

    2010-01-01

    Full Text Available Individual, familiar and sociocultural factors that could associate to initiation of sexual activity in adolescents of schools of Villa San Francisco-Santa Anita, Lima-Peru in 2009 were determined. The research was quantitative, transversal, descriptive and correlational in a population of 90 school adolescents between 14 and 19 years-old of two mixed schools. A survey was applied and validated by expert judgements submitted to a pilot assay for its validity and statistical reliability. For determinate statistical significance was employed a binomial assay and Crombach Alpha coefficient. The best predictors for the initiation of sexual activity in adolescents were: at individual level (school repeating, attitude to initiation of sexual activity and self-appreciation, at familiar level (structure and familiar function and socio-cultural (lack of an adult, knowledge of sexuality and peer groups.

  3. Impact of Antidepressant Drugs on Sexual Function and Satisfaction.

    2015-11-01

    Pleasurable sexual activity is important in many human relationships and can provide a sense of physical, emotional and social well-being. Depressive symptoms and depressive illness are associated with impairments in sexual function and sexual dissatisfaction in untreated and treated patients. Most currently available antidepressant drugs are associated with development or worsening of sexual dysfunction in a substantial proportion of patients. Sexual difficulties during antidepressant treatment often resolve as depression lifts, but can persist over long periods, reducing self-esteem and affecting mood and relationships adversely. Sexual difficulties during antidepressant treatment typically have many possible causes but the incidence and nature of dysfunction varies between drugs. Many interventions can be considered when managing sexual dysfunction associated with antidepressants but no approach is 'ideal'. Because treatment-emergent sexual difficulties are less frequent with certain drugs, presumably related to differences in pharmacological properties, and since current interventions are suboptimal, a lower incidence of sexual dysfunction is a relevant tolerability target when developing novel antidepressants.

    The purpose of this clinical report is to provide pediatricians updated research on evidence-based sexual and reproductive health education conducted since the original clinical report on the subject was published by the American Academy of Pediatrics in 2001. Sexuality education is defined as teaching about human sexuality, including intimate relationships, human sexual anatomy, sexual reproduction, sexually transmitted infections, sexual activity, sexual orientation, gender identity, abstinence, contraception, and reproductive rights and responsibilities. Developmentally appropriate and evidence-based education about human sexuality and sexual reproduction over time provided by pediatricians, schools, other professionals, and parents is important to help children and adolescents make informed, positive, and safe choices about healthy relationships, responsible sexual activity, and their reproductive health. Sexuality education has been shown to help to prevent and reduce the risks of adolescent pregnancy, HIV, and sexually transmitted infections for children and adolescents with and without chronic health conditions and disabilities in the United States.

    Full Text Available Most of the failures of induction motors become insulation faults, causing a permanent damage. Using differential current transformers, a system capable of insulation fault detection was developed, based on the differential relay protection scheme. Both signal injection and fault detection circuitry were integrated in a single chip. The proposed scheme is faster than other existing protection and not restricted to protect induction motors, but several other devices (such as IGBTs and systems. This paper explains the principle of operation of fault protection scheme and analyzes an integrated implementation through simulations and experimental results.

  7. Conditioning and sexual behavior: a review.

    Science.gov (United States)

    Pfaus, J G; Kippin, T E; Centeno, S

    2001-09-01

    Sexual behavior is directed by a sophisticated interplay between steroid hormone actions in the brain that give rise to sexual arousability and experience with sexual reward that gives rise to expectations of competent sexual activity, sexual desire, arousal, and performance. Sexual experience allows animals to form instrumental associations between internal or external stimuli and behaviors that lead to different sexual rewards. Furthermore, Pavlovian associations between internal and external stimuli allow animals to predict sexual outcomes. These two types of learning build upon instinctual mechanisms to create distinctive, and seemingly "automated," patterns of sexual response. This article reviews the literature on conditioning and sexual behavior with a particular emphasis on incentive sequences of sexual behavior that move animals from distal to proximal with regard to sexual stimuli during appetitive phases of behavior and ultimately result in copulatory interaction and mating during consummatory phases of behavior. Accordingly, the role of learning in sexual excitement, in behaviors that bring about the opportunity to mate, in courtship and solicitation displays, in sexual arousal and copulatory behaviors, in sexual partner preferences, and the short- and long-term influence of copulatory experience on sexual and reproductive function is examined. Although hormone actions set the stage for sexual activity by generating the ability of animals to become sexually excited and aroused, it is each animal's unique experience with sexual behavior and sexual reward that molds the strength of responses made toward sexual incentives.

  8. 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.

    Wall conditioning will be required in ITER to control fuel and impurity recycling, as well as tritium (T) inventory. Analysis of conditioning cycle on the JET, with its ITER-Like Wall is presented, evidencing reduced need for wall cleaning in ITER compared to JET–CFC. Using a novel 2D multi-fluid model, current density during Glow Discharge Conditioning (GDC) on the in-vessel plasma-facing components (PFC) of ITER is predicted to approach the simple expectation of total anode current divided by wall surface area. Baking of the divertor to 350 °C should desorb the majority of the co-deposited T. ITER foresees the use of low temperature plasma based techniques compatible with the permanent toroidal magnetic field, such as Ion (ICWC) or Electron Cyclotron Wall Conditioning (ECWC), for tritium removal between ITER plasma pulses. Extrapolation of JET ICWC results to ITER indicates removal comparable to estimated T-retention in nominal ITER D:T shots, whereas GDC may be unattractive for that purpose.

    Human papilloma virus (HPV) and Chlamydia trachomatis are the most prevalent sexually transmitted infections (STIs), among teenagers and young people, with risk factors: active sex life and multiple partners. Chlamydia trachomatis infection may favor HPV infection and this, the development of cervical cancer. Both infections can lead to consequences on sexual and reproductive health. To determine frequency of HPV and C. trachomatis in asymptomatic university women less than 25 years, associating them with number of sexual partners (n°SxP) and time of sexual activity (TSxA). Material andMethods: 151 cervical samples for HPV and C. trachomatis, were processed by conventional and in real time reaction polymerase chain. HPV 21, 8%, C. trachomatis 11, 2% and co-infection (HPV/C.trachomatis), 4.6%. Aimong HPV +, 80, 6% showed high risk HPV. The n°SxP was strongly associated with HPV. Aimong young coinfected HPV/C. trachomatis, 71.4% had 3 or more PSx. Chlamydia trachomatis was more frequent (64,7%) that HPV within range of 3-5 years according to the TSxA, Discussion: A high prevalence of HPV and C. trachomatis was observed. Young women with coinfection HPV/C. trachomatis could be a high-risk group need to monitor their infections. It suggests the implementation of university programs in education, counseling and prevention in sexual health.

    Asparagus adscendens Roxb (Liliaceae) has a promising role in modulation of various disorders such as leucorrhea, diarrhea, dysentery, diabetes, senile pruritus, asthma, fatigue antifilarial, antifungal, spermatorrhea, and sexual debility/seminal weakness. To investigate dose-dependent effects of Asparagus adscendens root (AARR) extract on anabolic, reproductive, and sexual behavioral activities with a view to emphasize the pharmacological basis. Rats were divided into five groups: Group I (control), Groups II-IV (AARR treated, 100, 200, and 300 mg/kg body weight, respectively, orally for 30 d) and Group V (standard control treated with sildenafil citrate, 5 mg/kg body weight). On day 31, copulatory and potency tests were carried out and an autopsy was done to study the reproductive function, namely, organ weights, spermatogenesis, daily sperm production rate (DSP), and epididymal sperm counts (ESC). AARR extract (200 and 300 mg/kg doses) caused a significant increase in body (p < 0.02 and p < 0.001) and testes (p < 0.01 and p < 0.001, control versus treated) weights. Reproductive activity showed significant a increase in testicular tubular diameter (p < 0.005-0.001), the number of round/elongated spermatids (p < 0.02-0.001), DSP, and ESC (p < 0.05-0.001). The sexual behavioral parameters including mounting/intromission frequency (13.0 ± 0.32/11.8 ± 0.37 and 18.2 ± 2.12/14.8 ± 1.15 versus 11.2 ± 0.66/8.2 ± 1.16), ejaculation latency (187.4 ± 1.91 and 191.4 ± 1.72 versus 180.0 ± 3.47), and penile erections (13.5 ± 0.3 and 14.5 ± 0.5 versus 8.5 ± 0.2) showed a significant increase at 200 and 300 mg/kg doses (ED50 300 mg/kg), but less than a standard control. In contrast, 100 mg/kg dose caused an increase (p < 0.005) in mounting latency only. These results indicate increased anabolic, reproductive, and sexual activities by AARR treatment. Thus, the data provide

    The extensive and sometimes profoundly damaging effects of sexual violence and large numbers of victims necessitate dedicated attention to primary prevention efforts. Few studies have examined the scope of current prevention activities or their fit with empirical research into effective prevention strategies. The current article presents findings from a survey of primary prevention activities in non-Māori and bicultural communities within Aotearoa New Zealand. Forty-four respondents representing 42 agencies responded to a comprehensive survey that canvased types of sexual violence primary prevention activities undertaken, sexual violence primary prevention programs, and barriers and supports to sexual violence prevention work. Consistent with findings from previous international surveys, the focus of primary prevention work in New Zealand was on sexual violence education and increasing awareness. Findings are discussed in the context of the sexual violence prevention literature and what works in prevention more broadly to help identify promising initiatives as well as gaps in current practices. Recommendations for advancing sexual violence primary prevention research are also provided.

    Pyrazole are potent medicinal scaffolds and exhibit a full spectrum of biological activities. This review throws light on the detailed synthetic approaches which have been applied for the synthesis of pyrazole. This has been followed by an in depth analysis of the pyrazole with respect to their medical significance. This follow-up may help the medicinal chemists to generate new leads possessing pyrazole nucleus with high efficacy.

    Concerns about the impact of online sexual activities (OSA) on work-life are drastically increasing. This study examined 3,466 respondents who reported OSA, 18.5% of whom reported engaging in OSA at work. They were compared with the 81.5% who engaged in OSA at home, on average time spent in OSA, workplace policies regarding OSA, and relationship status. Two themes were identified and discussed: opportunity and sexual distress. Our findings indicate that participants are cognizant of issues of opportunity (e.g., the OSA from home group was more likely to indicate their workplace has established policies regarding OSA), and privacy, representing an important aspect of this theme (e.g., participants engaging in OSA at work were found to be twice as likely to have extra-marital affairs, compared with the OSA from home group). Secondly, our data suggests that many participants, especially from the OSA at work group, experience OSA-related distress. Engaging in OSA at the workplace may result in decreased productivity, issues of sexual harassment, and concerns about employee well-being. Clearly stated and consistently enforced policies regulating OSA are likely to mitigate workplace OSA. However, a significant minority of employees may have difficulties curbing OSA. Therefore, more sophisticated strategies to deal with workplace OSA should be established. Additional implications of importance for organizations and mental health professionals who support them are discussed.

    To examine the influence of sexual activity on the composition and consistency of the vaginal microbiota over time, and distribution of Gardnerella vaginalis clades in young women. Fifty-two participants from a university cohort were selected. Vaginal swabs were self-collected every 3-months for up to 12 months with 184 specimens analysed. The vaginal microbiota was characterised using Roche 454 V3/4 region 16S rRNA sequencing, and G.vaginalis clade typing by qPCR. A Lactobacillus crispatus dominated vaginal microbiota was associated with Caucasian ethnicity (adjusted relative risk ratio[ARRR] = 7.28, 95%CI:1.37,38.57,p = 0.020). An L.iners (ARRR = 17.51, 95%CI:2.18,140.33,p = 0.007) or G.vaginalis (ARRR = 14.03, 95%CI:1.22,160.69, p = 0.034) dominated microbiota was associated with engaging in penile-vaginal sex. Microbiota dominated by L.crispatus, L.iners or other lactobacilli exhibited greater longitudinal consistency of the bacterial communities present compared to ones dominated by heterogeneous non-lactobacilli (pmicrobiota of these young, relatively sexually inexperienced women. Women had consistent vaginal microbiota over time if lactobacilli were the dominant spp. present. Penile-vaginal sex did not alter the consistency of microbial communities but increased G.vaginalis clade diversity in young women with and without BV, suggesting sexual transmission of commensal and potentially pathogenic clades.

    Children with neurofibromatosis type 1 (NF1) develop low-grade brain tumors throughout the optic pathway. Nearly 50% of children with optic pathway gliomas (OPGs) experience visual impairment, and few regain their vision after chemotherapy. Recent studies have revealed that girls with optic nerve gliomas are five times more likely to lose vision and require treatment than boys. To determine the mechanism underlying this sexually dimorphic difference in clinical outcome, we leveraged Nf1 optic glioma (Nf1-OPG) mice. We demonstrate that female Nf1-OPG mice exhibit greater retinal ganglion cell (RGC) loss and only females have retinal nerve fiber layer (RNFL) thinning, despite mice of both sexes harboring tumors of identical volumes and proliferation. Female gonadal sex hormones are responsible for this sexual dimorphism, as ovariectomy, but not castration, of Nf1-OPG mice normalizes RGC survival and RNFL thickness. In addition, female Nf1-OPG mice have threefold more microglia than their male counterparts, and minocycline inhibition of microglia corrects the retinal pathology. Moreover, pharmacologic inhibition of microglial estrogen receptor-β (ERβ) function corrects the retinal abnormalities in female Nf1-OPG mice. Collectively, these studies establish that female gonadal sex hormones underlie the sexual dimorphic differences in Nf1 optic glioma-induced retinal dysfunction by operating at the level of tumor-associated microglial activation.

  8. The sport and the physical activity as mediators of corporal models: Genre and sexuality in learning of the masculinities

    2007-11-01

    Full Text Available This article begins with an analysis of some theoretical contributions about the conceptualization of body in contemporary societies. These allow us to set a dialogue with the reflective experiences of a group of teenagers about how they learn masculinitiesi in their lives. Phenomenological and political emphasis on the body carried out by Feminists -with the notion of embodiment- have been essential in giving complexity to embodied issues such as gender, race, age, social class (disabilities, etc. which not only operate in a relation of power in our selves, but also as a locus of resistance and agency. Queer theory and its deconstruction of normative sexuality -with the concept of performativity- will be basic to understand the fundamental role that sexuality has in the construction of subjectivities. The accounts of teens will allow us to explore the paper that physical activities and sport have in their lives as mediators in the construction of their "masculine" subjectivities, many times as an oppressor space of their sexual and gender identity, and open an analysis of the hegemonic body representations that mediate not only physical education in schools, but also sport of competition and elite, and their representations in mass media.

    2009-01-01

    Hypothesis of reproductive compensation (Gowaty et al., 2007) suggests that constraining of free mating preference leads to reduction of the viability of progenies, which could be, partially, compensated by higher fecundity of the constrained parents. We consider infection as one of natural causes constraining female mating choice, because infection or immune response to infection can modulate male sexual demonstrations. Here we studied influence of LPS (bacterial endotoxin, activating non-specific immune response) on chemical attractiveness, sexual behavior and reproductive success in the outbreed male mice mated with the non-treated females. Single or repeated LPS administrations lead to increase of scent attractiveness of the male urine and soiled bedding for the non-estrus females. Injection of LPS (dose 50 mkg/kg) did not suppress the male sexual behavior. Time from pairing to successful mating correlates positively with the body mass of 16 day embryo. Embryos development, assessed by their body mass, was reduced in the females mated with the LPS-treated males. Higher level of plasma progesterone found in the females mated with the LPS-treated males, and shift of successful mating to the later time did not compensate reduction of embryo mass. At the same time the females mated with the LPS-treated males showed lower embryo lost in comparison with the females mated with the control males.

    The Hv1 proton channel is evidently unique among voltage sensor domain proteins in mediating an intrinsic ‘aqueous’ H+ conductance (GAQ). Mutation of a highly conserved ‘gating charge’ residue in the S4 helix (R1H) confers a resting-state H+ ‘shuttle’ conductance (GSH) in VGCs and Ci VSP, and we now report that R1H is sufficient to reconstitute GSH in Hv1 without abrogating GAQ. Second-site mutations in S3 (D185A/H) and S4 (N4R) experimentally separate GSH and GAQ gating, which report thermodynamically distinct initial and final steps, respectively, in the Hv1 activation pathway. The effects of Hv1 mutations on GSH and GAQ are used to constrain the positions of key side chains in resting- and activated-state VS model structures, providing new insights into the structural basis of VS activation and H+ transfer mechanisms in Hv1.

    Yersinia outer protein M (YopM) belongs to the group of Yop effector proteins, which are highly conserved among pathogenic Yersinia species. During infection, the effectors are delivered into the host cell cytoplasm via the type 3 secretion system to subvert the host immune response and support the survival of Yersinia. In contrast to the other Yop effectors, YopM does not possess a known enzymatic activity and its molecular mechanism(s) of action remain(s) poorly understood. However, YopM was shown to promote colonization and dissemination of Yersinia, thus being crucial for the pathogen's virulence in vivo. Moreover, YopM interacts with several host cell proteins and might utilize them to execute its anti-inflammatory activities. The results obtained so far indicate that YopM is a multifunctional protein that counteracts the host immune defense by multiple activities, which are at least partially independent of each other. Finally, its functions seem to be also influenced by differences between the specific YopM isoforms expressed by Yersinia subspecies. In this review, we focus on the global as well as more specific contribution of YopM to virulence of Yersinia during infection and point out the various extra- and intracellular molecular functions of YopM. In addition, the novel cell-penetrating ability of recombinant YopM and its potential applications as a self-delivering immunomodulatory therapeutic will be discussed. Copyright © 2015 Elsevier GmbH.

    The aim of this paper is to introduce a simple and low-cost experimental setup that can be used to study the eddy current brake, which considers the motion of a sliding magnet on an inclined conducting plane in terms of basic physical principles. We present a set of quantitative experiments performed to study the influence of the geometrical and electromagnetic properties of the magnet on the magnetic drag force. This video-based experiment is ideal for the study of kinematic graphs and the application of Newton's laws. Video motion analysis software enables students to make precise measurements of the magnet's position at incremental times during its motion, thus allowing them to quantify electromagnetic induction phenomena. The equipment needed for this experiment and data collection software are present in most physics teaching laboratories or are inexpensive and available.

    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

    Adolescence is a tumultuous and challenging time period in life. Sexual risk behavior among adolescents is a widespread topic of interest in the current literature. Two common factors that influence increased sexual risk behavior are symptoms of depression and negative body image. The purpose of this study was to investigate the effect of body image and symptoms of depression upon sexual risk-taking in an adolescent female population. A secondary data analysis of the 2011 Youth Risk Behavior Survey (YRBS) was used to explore girls' sexual activity, body image, and mental health. There were 7,708 high-school girls who participated in this study. Three questions were used to represent the constructs under investigation. There were significant correlations between sexual activity, body image, and symptoms of depression; only symptoms of depression were significant predictors of both sexual activity and condom usage. Body image was a predictor of sexual activity, but not condom use. Our findings support previous studies that suggested that people with depressive symptoms were more likely to engage in risky sexual behaviors. Our study also supports the idea that a negative body image decreases sexual activity; however, other researchers have reported that negative body image leads to an increase in sexual activity.

    We examined sexual orientation disparities in physical activity, sports involvement, and obesity among a population-based adolescent sample. We analyzed data from the 2012 Dane County Youth Assessment for 13,933 students in grades 9 through 12 in 22 Wisconsin high schools. We conducted logistic regressions to examine sexual orientation disparities in physical activity, sports involvement, and body mass index among male and female adolescents. When we accounted for several covariates, compared with heterosexual females, sexual minority females were less likely to participate in team sports (adjusted odds ratio [AOR] = 0.44; 95% confidence interval [CI] = 0.37, 0.53) and more likely to be overweight (AOR = 1.28; 95% CI = 1.02, 1.62) or obese (AOR = 1.88; 95% CI = 1.43, 2.48). Sexual minority males were less likely than heterosexual males to be physically active (AOR = 0.62; 95% CI = 0.46, 0.83) or to participate in team sports (AOR = 0.26; 95% CI = 0.20, 0.32), but the 2 groups did not differ in their risk of obesity. Sexual orientation health disparities in physical activity and obesity are evident during adolescence. Culturally affirming research, interventions, and policies are needed for sexual minority youths.

    The facilities for neutron activation analysis in the HANARO (Hi-flux Advanced Neutron Application Research Reactor) are described and the main applications of NAA (Neutron Activation Analysis) are reviewed. The sample irradiation tube, automatic and manual pneumatic transfer system were installed at three irradiation holes of HANARO at the end of 1995. The performance of the NAA facility was examined to identify the characteristics of the tube transfer system, irradiation sites and custom-made polyethylene irradiation capsule. The available thermal neutron fluxes at irradiation sites are in the range of 3 x 10{sup 13} - 1 x 10{sup 14} n/cm{sup 2}{center_dot}s and cadmium ratios are in 15 - 250. For an automatic sample changer for gamma-ray counting, a domestic product was designed and manufactured. An integrated computer program (Labview) to analyse the content was developed. In 2001, PGNAA (Prompt Gamma Neutron Activation Analysis) facility has been installed using a diffracted neutron beam of ST1. NAA has been applied in the trace component analysis of nuclear, geological, biological, environmental and high purity materials, and various polymers for research and development. The improvement of analytical procedures and establishment of an analytical quality control and assurance system were studied. Applied research and development for the environment, industry and human health by NAA and its standardization were carried out. For the application of the KOLAS (Korea Laboratory Accreditation Scheme), evaluation of measurement uncertainty and proficiency testing of reference materials were performed. Also to verify the reliability and to validate analytical results, intercomparison studies between laboratories were carried out. (author)

    2012-04-01

    During the last few years the scientific community has shown a considerable interest in the study of plant materials as sources of new compounds to be processed into antimicrobial agents. In this context, carvacrol, a monoterpenic phenol, has emerged for its wide spectrum activity extended to food spoilage or pathogenic fungi, yeast and bacteria as well as human, animal and plant pathogenic microorganisms including drug-resistant and biofilm forming microorganisms. The antibacterial activity of carvacrol has been attributed to its considerable effects on the structural and functional properties of cytoplasmatic membrane. The data reported in this review provide an overview of the published literature regarding the antimicrobial properties of carvacrol and the recent patents claimed in order to highlight its future applications as a new antimicrobial agent. These could concern either the natural preservation in the cosmetic and food industries or an alternative which supports the conventional antimicrobial protocols. Interestingly, carvacrol alone or associated with one or more synergistic products could be incorporated in different formulations for biomedical and food packaging applications. However, more detailed safety investigations and in vivo studies should be carried out so that this molecule could be used in the future.

    Aut ophagy is the major intracellular degradation system,by which cytoplasmic materials are delivered to and degraded in the lysosome.As a quality control mechanism for cytoplasmic proteins and organelles,autophagy plays important roles in a variety of human diseases,including neurodegenerative diseases,cancer,cardiovascular disease,diabetes and infectious and inflammatory diseases.The discovery of ATG genes and the dissection of the signaling pathways involved in regulating autophagy have greatly enriched our knowledge on the occurrence and development of this lysosomal degradation pathway.In addition to its role in degradation,autophagy may also promote a type of programmed cell death that is different from apoptosis,termed type II programmed cell death.Owing to the dual roles of autophagy in cell death and the specificity of diseases,the exact mechanisms of autophagy in various diseases require more investigation.The application of autophagy inhibitors and activators will help us understand the regulation of autophagy in human diseases,and provide insight into the use of autophagy-targeted drugs.In this review,we summarize the latest research on autophagy inhibitors and activators and discuss the possibility of their application in human disease therapy.

    A sexual self-schema is a cognitive generalization about sexual aspects of the self. In the current study, we examined how an individual's sexual self-schema influenced the processing of self and partner related sexual information. Specifically, we investigated how sexual self-schemas related to own and partner sexual satisfaction and how they influenced perceptions of partner sexual satisfaction. Participants were 117 heterosexual couples in committed, long-term relationships. Both partners completed measures assessing their sexual self-schemas, their own sexual satisfaction, and perceptions of partner sexual satisfaction. Consistent with our predictions, own sexual schema was associated with own sexual satisfaction. For men, more positive sexual self-schemas were associated with greater sexual satisfaction, and for women, more negative sexual self-schemas were associated with lower sexual satisfaction. For both men and women, there was no significant association between own sexual self-schema and partner sexual satisfaction. Sexual self-schemas directly and indirectly influenced an individual's perception of the partner's sexual satisfaction, such that men and women with more positive sexual self-schemas rated their partners as more sexually satisfied, after controlling for the partner's self-reported level of sexual satisfaction. Our findings demonstrated that sexual self-schemas are relevant to own sexual satisfaction as well as the processing of interpersonally relevant sexual information, specifically one's perceptions of partner sexual satisfaction.

  7. Aging and sexuality.

    Recent research suggesting that a high proportion of men and women remain sexually active well into later life refutes the prevailing myth that aging and sexual dysfunction are inexorably linked. Age-related physiological changes do not render a meaningful sexual relationship impossible or even necessarily difficult. In men, greater physical stimulation is required to attain and maintain erections, and orgasms are less intense. In women, menopause terminates fertility and produces changes ste...

    The impact of types of social connectedness-family, other adult, and school-on suicide ideation and attempts among all youth, the relative impact of each type, and effect modification by sexual orientation was assessed. Data were from the 2007-2009 Milwaukee Youth Risk Behavior Surveys. Multivariable logistic regression analyses calculated the risk of suicide ideation and attempts by sexual orientation, types of social connectedness, and their interaction. Among all youth, each type of connectedness modeled singly conferred protective effects for suicide ideation. Family and other adult connectedness protected against suicide attempts. When modeled simultaneously, family connectedness protected against ideation and attempts. Sexual orientation modified the association between other adult connectedness and suicide ideation. Findings suggest that family connectedness confers the most consistent protection among all youth and sexual orientation does not generally modify the association between connectedness and suicidal behavior.

    We examined the influence of perceived parental sexual values, religiosity, and family environment on young adults' sexual values from the United States (n = 218), Spain (n = 240), Costa Rica (n = 172), and Peru (n = 105). On average, and across the four national groups, the messages young adults received from their parents about broad domains of sexual behaviors (masturbation, non-intercourse types of heterosexual sexual activity, premarital sex, same-sex activity, and cohabiting) were unequivocally restrictive. By contrast, across the four groups, young adults on average held rather permissive sexual values and their values differed significantly from those of their parents. Moreover, the nature of perceived parental sexual values (restrictive vs. permissive) was not associated significantly with young adults' sexual values, age of sexual debut, or number of sexual partners. Comparatively, Spanish young adults held the most permissive sexual values, whereas US young adults held the most restrictive sexual values. Religiosity was the strongest predictor of young adults' sexual values, followed by perceived parental sexual values and influence. In conclusion, it appears that despite having perceived restrictive parental messages about sex, these young adults currently hold permissive sexual attitudes, thus calling into question the influence parents actually have on their adult children's sexual values.

  11. The implications of sexual narcissism for sexual and marital satisfaction.

    There is theoretical reason to believe narcissism is associated with a number of sexual behaviors and outcomes that affect both sexual and relationship satisfaction. Nevertheless, research on the association between personality and behavior demonstrates that personality traits, such as narcissism, only predict behavior in domains that activate the components of the personality system. Given that global assessments of narcissism do not capture the extent to which the components of narcissism are activated in the sexual domain, we examined the extent to which the facets of a domain-specific measure of sexual narcissism accounted for the trajectories of own and partner sexual and marital satisfaction over the first five years of 120 new marriages. Three of the four facets of sexual narcissism (sexual exploitation, sexual entitlement, and low sexual empathy) were negatively associated with both trajectories. The fourth facet (sexual skill) was positively associated with both trajectories. Notably, sexual satisfaction mediated the effect of every facet of sexual narcissism on marital satisfaction. A global assessment of narcissism was not associated with either trajectory of satisfaction. These findings highlight (1) the importance of narcissistic tendencies for sexual processes, (2) the benefits of using domain-specific measures of personality in research on sexual behavior, and (3) the importance of examining the implications of the specific facets of personality constructs.

    Integrating sexual health in clinical practice is important. In women with pelvic floor disorders, the evaluation of the anatomical defects, lower urinary tract function and the anorectal function often receives more attention than the sexual function. Review of Medline using defined search terms to identify articles related to sexual health assessment in urogynecology and manual analyses was performed. Only articles published in English or Spanish were included. Only 50% of women attending urogynecological clinics are sexually active. Of those, 60% present with some sort of sexual sexual dysfunction (FSD). Questionnaires and sexuality scales would facilitate discussion of sexual matters between the Health Care professionals and the women, and may increase the likelihood of FSD being diagnosed. The Pelvic Organ Prolapse Incontinence Sexual Questionnaire (PISQ) and the PISQ-IR (IUGA-Revised) are the only female sexual function specific questionnaires currently validated and developed specifically to assess sexual function in women with urinary incontinence and/or pelvic organ prolapse. Furthermore, the PISQ-IR also allows evaluation of the outcomes of women who are not sexually active when requiring urogynecologic care. PISQ-IR is also designed for international validation. In order to use the PISQ-IR in Spain, a proper interpretation and validation of the questionnaire is needed. The evaluation of sexual function through specific questionnaires facilitates the identification of the sexual dysfunctions associated to the pelvic floor disorders. The inclusion of sexuality questionnaires as an outcome measure allows to analyze the impact in the sexual life of women treated for an urogynecological problem. Copyright © 2014 AEU.

    Full Text Available Abstract Background The prostate is a sexual gland that produces important substances for the potency of sperm to fertilize eggs within the female reproductive tract, and is under complex endocrine control. Taking advantage of the peculiar behavioral pattern of copulating male rats, we developed experimental paradigms to determine the influence of sexual behavior on the level of serum testosterone, prostate androgen receptors, and mRNA for androgen receptors in male rats displaying up to four consecutive ejaculations. Methods The effect of four consecutive ejaculations was investigated by determining levels of (i testosterone in serum by solid phase RIA, (ii androgen receptors at the ventral prostate with Western Blots, and (iii androgen receptors-mRNA with RT-PCR. Data were analyzed with a one-way ANOVA followed by a post hoc application of Dunnett's test if required. Results The constant execution of sexual behavior did not produce any change in the weight of the ventral prostate. Serum testosterone increased after the second ejaculation, and remained elevated even after four ejaculations. The androgen receptor at the ventral prostate was higher after the first to third ejaculations, but returned suddenly to baseline levels after the fourth ejaculation. The level of mRNA increased after the first ejaculation, continued to increase after the second, and reached the highest peak after the third ejaculation; however, it returned suddenly to baseline levels after the fourth ejaculation. Conclusion Four consecutive ejaculations by sexually experienced male rats had important effects on the physiological responses of the ventral prostate. Fast responses were induced as a result of sexual behavior that involved an increase and decrease in androgen receptors after one and four ejaculations, respectively. However, a progressive response was observed in the elevation of mRNA for androgen receptors, which also showed a fast decrease after four

Especially traumas during neuron plasticity phase may lead hypersensitivity of neuroendocrine stress response. Early life stresses are shown to lead changes in corticotrophin releasing factor system in preclinical and clinical phase studies. In the treatment of sexual abuse, emotional process related with trauma should be focused on. This process may be conducted with play therapy. Development of higher level defense mechanism, increasing ego capacity, orientation to social activity and personal activity according to skills is aimed. For the elimination of guiltiness related with stigmatization, the child should be told that it is not herhis fault to incorporate into sexual interaction and the culprit is abuser. It is fairly important for medical staff, school and family to have sufficient information about sexual abuse for prevention and early recognition.

  16. Profiles for voltage-activated currents are multiphasic, not curvilinear

    Data for voltage-activation of a potassium channel (Matulef et al. Proc Natl Acad Sci USA 110: 17886-17891. 2013) were, as conventionally done, fitted by the authors by a Boltzmann function, i.e. by a curvilinear profile. Reanalysis of the data reveals however that this interpretation must be rejected in favor of a multiphasic profile, a series of straight lines separated by discontinuous transitions, quite often in the form of noncontiguities (jumps). In contrast to the generally very poor fits to the Boltzmann profiles, the fits to multiphasic profiles are very good. (For the four replicates, the average deviations from the Boltzmann curves were 10- to 100-fold larger than the deviations from the multiphasic profiles.) The difference in the median values was statistically highly significant, P<0.001 in most cases. For the mean values the deviations from the Boltzmann curve were 20-fold larger than the deviations from the multiphasic profile, and the difference in the median values was also highly signifi...

  17. AIDS education, condom demand, and the sexual activity of American youth.

    This paper examines the effects of AIDS education at school and at home on the sexual behavior of American youth. Multinomial logit equations of the probabilities of abstinence, sexual intercourse with a condom, and intercourse without a condom are estimated using data from the Youth Risk Behavior Supplement of the 1992 National Health Interview Survey. We find no significant effects of AIDS education on the probability of abstinence, but we do find that AIDS education significantly raises the likelihood of condom-protected relative to unprotected intercourse. These results indicate that risk-altering and risk-revealing AIDS education dominate any utility-altering effects favoring intercourse over abstinence. We also find that young women are influenced by AIDS education to a greater extent than young men. Overall, our results suggest that educating young people about AIDS does not promote sex and encourages safer sex, reducing the likelihood of HIV transmission and lowering the subsequent social costs.

    This study estimated prevalence of HIV risk behaviors and its association with substance use and mental health problems among adolescents in treatment. A pooled dataset of 9,519 adolescents admitted to substance abuse treatment programs between 2002 and 2006 was analyzed. HIV risk behaviors, substance use, and mental health problems were assessed at treatment intake. Sixty percent of adolescents were engaged in at least one sexual or needle use risk behavior in the year prior to entering treatment. Sex with multiple partners, sex under the influence of alcohol or drugs, and unprotected sex were the most prevalent HIV risk behaviors. Several gender differences were found for specific types of sexual and needle use behaviors. Adolescents with substance dependence or other comorbid mental health problems were at increased odds for HIV risk. Findings suggest treatment programs may benefit adolescents better by screening them consistently for HIV risk behaviors and incorporating tailored interventions.

  19. The Current Case of Quinolones: Synthetic Approaches and Antibacterial Activity

    Full Text Available Quinolones are broad-spectrum synthetic antibacterial drugs first obtained during the synthesis of chloroquine. Nalidixic acid, the prototype of quinolones, first became available for clinical consumption in 1962 and was used mainly for urinary tract infections caused by Escherichia coli and other pathogenic Gram-negative bacteria. Recently, significant work has been carried out to synthesize novel quinolone analogues with enhanced activity and potential usage for the treatment of different bacterial diseases. These novel analogues are made by substitution at different sites—the variation at the C-6 and C-8 positions gives more effective drugs. Substitution of a fluorine atom at the C-6 position produces fluroquinolones, which account for a large proportion of the quinolones in clinical use. Among others, substitution of piperazine or methylpiperazine, pyrrolidinyl and piperidinyl rings also yields effective analogues. A total of twenty six analogues are reported in this review. The targets of quinolones are two bacterial enzymes of the class II topoisomerase family, namely gyrase and topoisomerase IV. Quinolones increase the concentration of drug-enzyme-DNA cleavage complexes and convert them into cellular toxins; as a result they are bactericidal. High bioavailability, relative low toxicity and favorable pharmacokinetics have resulted in the clinical success of fluoroquinolones and quinolones. Due to these superior properties, quinolones have been extensively utilized and this increased usage has resulted in some quinolone-resistant bacterial strains. Bacteria become resistant to quinolones by three mechanisms: (1 mutation in the target site (gyrase and/or topoisomerase IV of quinolones; (2 plasmid-mediated resistance; and (3 chromosome-mediated quinolone resistance. In plasmid-mediated resistance, the efflux of quinolones is increased along with a decrease in the interaction of the drug with gyrase (topoisomerase IV. In the case of

    Cat odors induce rapid, innate and stereotyped defensive behaviors in rats at first exposure, a presumed response to the evolutionary pressures of predation. Bizarrely, rats infected with the brain parasite Toxoplasma gondii approach the cat odors they typically avoid. Since the protozoan Toxoplasma requires the cat to sexually reproduce, this change in host behavior is thought to be a remarkable example of a parasite manipulating a mammalian host for its own benefit.

    Selective serotonin reuptake inhibitors (SSRIs) are associated with significant sexual side effects. By definition, all SSRIs increase overall serotonin (5HT) by binding to serotonin autoreceptors (5HTI A); however, each SSRI has a unique portfolio of secondary binding properties to other neurotransmitters such as norepinephrine (NE). As 5HTI A receptors mediate NE neurotransmission, SSRIs that are highly selective for 5HTI A are more likely to reduce NE efficiency; however, in SSRIs that are...

    Full Text Available In this paper, the hysteresis current control (HCC technique based on space vector modulation (SVM for shunt active power filter (APF is proposed. The switching control algorithms of the HCC based SVM manage to generate compensated current according to the reference current. Harmonics extraction is based on the instantaneous active and reactive power theorem in time domain by calculating the power compensation. A closed loop control system is carried out and the error current is the difference between the reference current which is obtained from the power compensation and the actual current needs to be injected back into the power grid. By implementing this control strategy, the APF manages to generate better compensated harmonics currents to the power grid.

    In the World Health Organization's forthcoming eleventh revision of the International Classification of Diseases and Related Health Problems (ICD-11), substantial changes have been proposed to the ICD-10 classification of mental and behavioural disorders related to sexuality and gender identity. These concern the following ICD-10 disorder groupings: F52 Sexual dysfunctions, not caused by organic disorder or disease; F64 Gender identity disorders; F65 Disorders of sexual preference; and F66 Psychological and behavioural disorders associated with sexual development and orientation. Changes have been proposed based on advances in research and clinical practice, and major shifts in social attitudes and in relevant policies, laws, and human rights standards. This paper describes the main recommended changes, the rationale and evidence considered, and important differences from the DSM-5. An integrated classification of sexual dysfunctions has been proposed for a new chapter on Conditions Related to Sexual Health, overcoming the mind/body separation that is inherent in ICD-10. Gender identity disorders in ICD-10 have been reconceptualized as Gender incongruence, and also proposed to be moved to the new chapter on sexual health. The proposed classification of Paraphilic disorders distinguishes between conditions that are relevant to public health and clinical psychopathology and those that merely reflect private behaviour. ICD-10 categories related to sexual orientation have been recommended for deletion from the ICD-11.

    The current longitudinal study explores the relationship between adolescent television use at time 1 and sexual experience and relationship status (i.e., committed/romantic versus casual) 1 year later. The sample (N = 824) comprised youth aged 14-18. Multinomial logistic regressions predicting group membership from television exposure variables were conducted controlling for socio-demographic characteristics and prior sexual behavior. Results indicate that sexually inexperienced youth watched more television overall than sexually experienced youth, but less adult, premium and music television on cable networks. Premium cable exposure predicted group membership among sexually active youth. Youth who watched more premium cable at time 1 were more likely to be in casual relationship at last intercourse than a committed one. A more complete understanding of media effects on adolescent sexual relationships can help guide policy development, media education/literacy efforts, and contribute to the design of interventions to reduce the negative consequences associated with adolescent sexual behavior.

    This article has two overall goals. First, to examine the current state of sexual violence research to highlight several shortcomings in the knowledge on partner sexual violence. Second, to describe several factors to consider in future research to facilitate a more in-depth understanding of partner sexual violence. Shortcomings of the research on partner sexual violence include (1) overreliance on dichotomous yes/no representations of sexual violence experiences; (2) lack of, or inadequate documentation of the scope and nature of partner sexual violence; (3) inadequate ways to account for impairment of consent under different circumstances; (4) difficulties in discriminating unwanted from nonconsensual sexual activities; and (5) limited information about the role sexual violence plays in the larger context of coercive control. In order to facilitate a more in-depth understanding of partner sexual assault, there is a need (1) to better understand the scope and nature of partner sexual assault and (2) to better understand the role partner sexual violence plays in coercive control. By improving the measurement of this phenomenon, victims, researchers, practitioners, and those involved in the justice system might be better equipped to respond to sexual violence among intimate partners.
