Abstract Oral contraceptives (OCs) following induced abortion offer a reliable method to avoid repeated abortion. However, limited data exist supporting the effective use of OCs postabortion. We conducted this systematic review and meta-analysis in the present study reported immediate administration of OCs or combined OCs postabortion may reduce vaginal bleeding time and amount, shorten the menstruation recovery period, increase endometrial thickness 2 to 3 weeks after abortion, and reduce the risk of complications and unintended pregnancies. A total of 8 major authorized Chinese and English databases were screened from January 1960 to November 2014. Randomized controlled trials in which patients had undergone medical or surgical abortions were included. Chinese studies that met the inclusion criteria were divided into 3 groups: administration of OC postmedical abortion (group I; n = 1712), administration of OC postsurgical abortion (group II; n = 8788), and administration of OC in combination with traditional Chinese medicine postsurgical abortion (group III; n = 19,707). In total, 119 of 6160 publications were included in this analysis. Significant difference was observed in group I for vaginal bleeding time (P = 0.0001), the amount of vaginal bleeding (P = 0.03), and menstruation recovery period (P abortion (P abortion, and reduce the risk of complications and unintended pregnancies.

Margel, David; Fleshner, Neil E

2011-01-01

Background Several recent studies have suggested that oestrogen exposure may increase the risk of prostate cancer (PCa). Objectives To examine associations between PCa incidence and mortality and population-based use of oral contraceptives (OCs). It was hypothesised that OC by-products may cause environmental contamination, leading to an increased low level oestrogen exposure and therefore higher PCa incidence and mortality. Methods The hypothesis was tested in an ecological study. Data from the International Agency for Research on Cancer were used to retrieve age-standardised rates of prostate cancer in 2007, and data from the United Nations World Contraceptive Use 2007 report were used to retrieve data on contraceptive use. A Pearson correlation and multivariable linear regression were used to associate the percentage of women using OCs, intrauterine devices, condoms or vaginal barriers to the age standardised prostate cancer incidence and mortality. These analyses were performed by individual nations and by continents worldwide. Results OC use was significantly associated with prostate cancer incidence and mortality in the individual nations worldwide (r=0.61 and r=0.53, respectively; pnation's wealth. Conclusion A significant association between OCs and PCa has been shown. It is hypothesised that the OC effect may be mediated through environmental oestrogen levels; this novel concept is worth further investigation.

Considerable advances have been made in hormonal contraception in recent years, geared at maximizing compliance and minimizing discontinuation. In oral contraceptive (OC) formulations, the estrogenic component, generally ethinyl estradiol (EE), has been reduced significantly and newer progestins like dienogest and drospirenone (DRSP), compounds with different molecular structures, have been introduced; in addition, new regimens (extended, flexible, 24/4 formats instead of the standard 21/7 format) and innovative delivery systems (vaginal rings, transdermal patches, subcutaneous implants and intrauterine devices) are available. The multitude of choices allows hormonal contraception to be tailored to the individual woman in order to obtain non-contraceptive benefits, without significant side effects, and also a favorable risk/benefit profile for her general and reproductive health. Over the past few years, new OC formulations combining DRSP (3 mg), a unique progestin with both antimineralocorticoid and antiandrogenic activities, with estrogen (30 mcg or 20 mcg EE), in two regimens (24/4 and 21/7) of active pills in a 28-day cycle, have shown positive effects on water retention-related weight gain and physical, emotional and psychosexual well-being. It seems likely that the use of a low-dose, well-balanced OC and the shorter 4-day hormone-free interval may minimize the side effects that can impair quality of life and thus increase women's compliance with hormonal contraception therapy.

This study examines the compliance, use behaviour and knowledge of method of women using injectable and oral contraceptives in two clinic sites in the Johannesburg area, South Africa. An interviewer administered questionnaire was used to collect information in the clients' home language. A total of 400 women were interviewed in the clinics. The mean age of clients was 26.2 years (range 13 to 43 years). Of the clients not wanting to get pregnant, 30.4 per cent of injectable users and 18.4 per cent of oral contraceptive (OC) users had stopped using their method temporarily before returning to the same method (called the nonuse segment) and had not used any other form of contraception during this time. Almost one third of injectable users (31.2 per cent) had been late for their next injection at least once. Although nearly all women using injectables had experienced some menstrual disturbances, over one third (38.5 per cent) had not been informed by the providers about the possibility of these changes. Many women gave the disruption of their menstrual cycle as the reason for the nonuse segment. The majority of OC users lacked information on how to use their method correctly. Nearly all women expressed an interest in obtaining more information on their current method and other available methods. This study shows that compliance is an issue in injectable as well as OC users.

Montoya, Estrella R; Bos, Peter A

2017-02-01

Millions of women worldwide use oral contraceptives ('the pill'; OCs), often starting at a pubertal age when their brains are in a crucial developmental stage. Research into the social-emotional effects of OCs is of utmost importance. In this review, we provide an overview of studies that have emerged over the past decade investigating how OCs, and their main ingredients estradiol (E) and progesterone (P), influence social-emotional behaviors and underlying brain functions. Based on this overview, we present a heuristic model that postulates that OCs modulate core social-emotional behaviors and brain systems. Research domains and challenges for the future, as well as implications, are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

Oral contraceptives increase the thrombotic risk in women with factor V Leiden. Emotional aspects of genetic testing prior to the prescription of oral contraceptives (OC), aspects of counseling and referral patterns are widely unknown. Two hundred forty-seven women with and 132 women without factor V Leiden were interviewed by questionnaire. One hundred sixty-one women (65%) with factor V Leiden and 63 (48%) with wild-type factor V responded. One hundred seventy-one women (76%) reported being emotionally disturbed by genetic testing. Eighty percent of women with factor V Leiden and 16% of women with wild-type factor V were discouraged from OC use. Three percent of women with factor V Leiden were encouraged to take OC. Forty-one percent of women with factor V Leiden used at least one hormone contraceptive method after diagnosis. Only 46 women (29%) with factor V Leiden were counseled about the relevance of the mutation in case of pregnancy. Testing for factor V Leiden has considerable emotional impact. Recommendations after testing are not consistently driven by the test result.

This pilot study evaluated the effects of a desogestrel-containing oral contraceptive (DSG-OC) on facial seborrhea (oiliness), acne and related factors in otherwise healthy women with moderate facial acne vulgaris. In this double-blind, placebo-controlled study, 41 women received DSG-OC (50/100/150 microg desogestrel plus 35/30/30 microg ethinylestradiol given in a 7/7/7 day regimen) and 41 received placebo for six cycles. Seborrhea and skin assessments, and hormone analyses were performed regularly. Analyses of sebum output (measured using Sebutape) indicated that the effect of DSG-OC on the skin varied with facial area. Compared with placebo, DSG-OC had a statistically significant effect on the cheeks (60% relative reduction in sebum output; p = 0.02), and a non-significant effect on the forehead (30% relative reduction in sebum output). Acne lesion counts did not differ significantly between groups. Both patient and investigator assessments of skin condition (visual analog scale) indicated significant improvements with DSG-OC compared with placebo. The reduced sebum output with DSG-OC is associated with a three-fold increase in sex hormone binding globulin, as well as an expected decrease in free testosterone and other androgens that were found in this group. These results suggest that DSG-OC reduces facial oiliness and may be a useful contraceptive choice for women with this problem.

To analyze the prevalence of current use of oral and injectable contraceptives by Brazilian women, according to demographic and socioeconomic variables and issues related to access to those medicines. A cross-sectional, population-based analytical study with probability sampling based on data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), carried out between September 2013 and February 2014 in 20,404 Brazilian urban households. Prevalence was calculated based on reports from non-pregnant women aged 15-49 on the use of oral or injectable contraceptives. The independent variables were gender, age, level of education, socioeconomic class, Brazilian region and marital status. Also analyzed were access, means of payment, sources, and reported medicines. Statistical analyses considered 95% confidence intervals (95%CI) and Pearson Chi-square test to evaluate the statistical significance of differences between groups, considering a 5% significance level. Prevalence of use was 28.2% for oral contraceptives (OC) and 4.5% for injectable contraceptives (IC). The highest prevalence of oral contraceptives was in the South region (37.5%) and the lowest in the North region (15.7%). For injectable contraceptives there was no difference between regions. Access was higher for oral contraceptive users (90.7%) than injectable contraceptives users (81.2%), as was direct payment (OC 78.1%, IC 58.0%). Users who paid for contraceptives acquired them at retail pharmacies (OC 95.0% and IC 86.6%) and at Farmácia Popular (Popular Pharmacy Program) (OC 4.8% and IC 12.7%). Free of charge contraceptives were mostly obtained from the Brazilian Unified Health System - SUS (OC 86.7%; IC 96.0%). Free samples were reported by 10.4% of users who did not pay for oral contraceptives. Most of paying users did not try to obtain contraceptives from SUS. Monophasic

This study evaluated contraceptive refill patterns of women insured commercially in the US who switched from oral contraceptives (OCs) to the patch or vaginal ring and assessed if switching contraceptive methods changes refill patterns. Women aged 15-44 with ≥2 patch or ring prescriptions and ≥2 OC prescriptions before the first patch/ring prescription were identified from the MarketScan® Commercial database (1/1/2002-6/30/2011). Refill patterns 1-year pre- and postindex date (first patch/ring prescription) were evaluated, and women were categorized as timely or delayed refillers on OCs and patch/ring. Regression modeling was used to investigate the association between refill patterns and contraceptive methods and switching effects on refill patterns. Of 17,814 women identified, 7901 switched to the patch, and 9913 switched to the ring. Among timely OC refillers, the percentage of timely refills decreased (patch: 95.6% to 79.4%, pcontraceptive efficacy by simply switching to the patch or ring. The impact on timely refills of switching from OCs to either the patch or ring is complex and varies depending on the pattern of timely refills on OCs. Copyright © 2014 Elsevier Inc.

2003-09-01

To compare the influence of oral hormonal contraceptives (OCs) and the use of intrauterine contraceptive devices (IUDs) on the modification of sexual desire. A prospective observational study of 1073 women using OCs or an IUD at the Family Planning Center 'Marina Alta' in Alicante, Spain. In order to evaluate the relative risk regarding the decrease in libido attributed to each contraceptive method, a logistic regression analysis was undertaken which considered the factors of age adjustment, level of studies, family planning information, relationship with partner, age when sexual relationships were initiated, parity, contraceptive method previously used and the duration of use of the contraceptive method. No differences in the decrease of sexual desire were observed between the use of the OC and IUD (odds ratio (OR) 1.32; 95% confidence interval (CI) 0.70-2.49), yet differences were noted, however, in relation to age (OR 1.05; 95% CI 1.01-1.10). Although these differences were not statistically significant, a high level of awareness regarding family planning was shown to increase sexual desire when compared to a lower level of information on this subject (OR 0.64; 95% CI 0.41-1.01). Sexual desire was seen to decrease if the quality of the relationship with the partner was average (OR 2.24; 95% CI 1.36-3.69) or poor (OR 4.69; 95% CI 1.93-11.4). Nulliparous women showed a greater decrease in sexual desire in relation to women who had already given birth (OR 1.57; 95% CI 1.00-2.47). Sexual desire was greater if the contraceptive method had already been in use for 6-12 months (OR 0.41; 95% CI 0.17-0.98). Sexual desire does not vary in relation to the use of OCs or IUDs, yet it does decrease with age, in nulliparous women and in those with an average or poor relationship with their partner. Furthermore, sexual desire shows an increase between the first 6 and 12 months of contraceptive treatment.

The association between oral contraceptive (OC) pills and vascular diseases is well-known, although, the present generation of pills is considered to be relatively safer in this regard. Hormonal treatment for severe abnormal uterine bleeding is usually considered after ruling out malignancy, when such bleeding is resistant to all other forms of treatment. We report a case of severe peripheral arterial disease in a female, who had been on high-dose OC pills for an extended period of time for severe uterine bleeding.

Affective responsiveness is influenced by intake of oral contraceptives.

Science.gov (United States)

Radke, Sina; Derntl, Birgit

2016-06-01

Despite the widespread use of oral contraceptive pills (OCs), little is known about their impact on psychological processes and emotional competencies. Recent data indicate impaired emotion recognition in OC users compared to naturally cycling females. Building upon these findings, the current study investigated the influence of OC use on three components of empathy, i.e., emotion recognition, perspective-taking, and affective responsiveness. We compared naturally cycling women to two groups of OC users, one being tested in their pill-free week and one in the phase of active intake. Whereas groups did not differ in emotion recognition and perspective-taking, an effect of pill phase was evident for affective responsiveness: Females currently taking the pill showed better performance than those in their pill-free week. These processing advantages complement previous findings on menstrual cycle effects and thereby suggest an association with changes in endogenous and exogenous reproductive hormones. The current study highlights the need for future research to shed more light on the neuroendocrine alterations accompanying OC intake. Copyright © 2016 Elsevier B.V. and ECNP. All rights reserved.

Antibiotics and oral contraceptives.

DeRossi, Scott S; Hersh, Elliot V

2002-10-01

With the exception of rifampin-like drugs, there is a lack of scientific evidence supporting the ability of commonly prescribed antibiotics, including all those routinely employed in outpatient dentistry, to either reduce blood levels and/or the effectiveness of oral contraceptives. To date, all clinical trials studying the effects of concomitant antibiotic therapy (with the exception of rifampin and rifabutin) have failed to demonstrate an interaction. Like all drugs, oral contraceptives are not 100% effective with the failure rate in the typical United States population reported to be as high as 3%. It is thus possible that the case reports of unintended pregnancies during antibiotic therapy may simply represent the normal failure rate of these drugs. Considering that both drug classes are prescribed frequently to women of childbearing potential, one would expect a much higher rate of oral contraceptive failure in this group of patients if a true drug:drug interaction existed. On the other hand, if the interaction does exist but is a relatively rare event, occurring in, say, 1 in 5000 women, clinical studies such as those described in this article would not detect the interaction. The pharmacokinetic studies of simultaneous antibiotic and oral contraceptive ingestion, and the retrospective studies of pregnancy rates among oral contraceptive users exposed to antibiotics, all suffer from one potential common weakness, i.e., their relatively small sample size. Sample sizes in the pharmacokinetic trials ranged from 7 to 24 participants, whereas the largest retrospective study of pregnancy rates still evaluated less than 800 total contraceptive users. Still, the incidence of such a rare interaction would not differ from the accepted normal failure rate of oral contraceptive therapy. The medico-legal ramifications of what looks like at best a rare interaction remains somewhat "murky." On one hand, we have medico-legal experts advising the profession to exercise caution

Comparison of Postprandial Lipemia between Women who are on Oral Contraceptive Methods and Those who are not

Directory of Open Access Journals (Sweden)

Jefferson Petto

2014-09-01

Full Text Available Background: Postprandial Lipemia (PPL is a physiological process that reflects the ability of the body to metabolize lipids. Even though the influence of oral contraceptives (OC on PPL is not known, it is a known fact that their use increases fasting lipid values. Objective: To compare the PPL between women who are on OC and those who are not. Methods: A prospective analytical study which assessed eutrophic women, aged between 18 and 28 years old, who were irregularly active and with fasting triglycerides ≤150 mg/dL. They were divided into two groups: oral contraceptive group (COG and non-oral contraceptive group (NCOG. Volunteers were submitted to the PPL test, in which blood samples were collected in time 0 (12-hour fasting and after the intake of lipids in times 180 and 240 minutes. In order to compare the triglyceride deltas, which reflect PPL, the two-tailed Mann-Whitney test was used for independent samples between fasting collections and 180 minutes (Δ1 and between fasting and 240 minutes (Δ2. Results: Forty women were assessed and equally divided between groups. In the fasting lipid profile, it was observed that HDL did not present significant differences and that triglycerides in COG were twice as high in comparison to NCOG. Medians of Δ1 and Δ2 presented significant differences in both comparisons (p ≤0.05. Conclusion: The results point out that women who are irregularly active and use OC present more PPL in relation to those who do not use OC, which suggests that in this population, its chronic use increases the risk of heart conditions.

The disposition of clofibric acid, a drug metabolised largely by glucuronidation, was studied in eight males, eight females and eight females receiving oral contraceptive steroids (OCS). Clofibric acid plasma clearance was not significantly different in males compared to the control female group but was 48% greater (P less than 0.01) in women receiving OCS compared to non-pill using females. This difference was due to an alteration in clofibric acid metabolic clearance as there were no differ...

Oral contraceptives and neuroactive steroids.

Science.gov (United States)

Rapkin, Andrea J; Biggio, Giovanni; Concas, Alessandra

2006-08-01

A deregulation in the peripheral and brain concentrations of neuroactive steroids has been found in certain pathological conditions characterized by emotional or affective disturbances, including major depression and anxiety disorders. In this article we summarize data pertaining to the modulatory effects of oral contraceptive treatment on neuroactive steroids in women and rats. Given that the neuroactive steroids concentrations are reduced by oral contraceptives, together with the evidence that a subset of women taking oral contraceptives experience negative mood symptoms, we propose the use of this pharmacological treatment as a putative model to study the role of neuroactive steroids in the etiopathology of mood disorders. Moreover, since neuroactive steroids are potent modulators of GABA(A) receptor function and plasticity, the treatment with oral contraceptives might also represent a useful experimental model to further investigate the physiological role of these steroids in the modulation of GABAergic transmission.

History of oral contraception.

On the 50th birthday of the pill, it is appropriate to recall the milestones which have led to its development and evolution during the last five decades. The main contraceptive effect of the pill being inhibition of ovulation, it may be called a small miracle that this drug was developed long before the complex regulation of ovulation and the menstrual cycle was elucidated. Another stumbling block on its way was the hostile climate with regard to contraception that prevailed at the time. Animal experiments on the effect of sex steroids on ovulation, and the synthesis of sex steroids and orally active analogues were the necessary preliminaries. We owe the development of oral contraceptives to a handful of persons: two determined feminists, Margaret Sanger and Katherine McCormick; a biologist, Gregory Pincus; and a gynaecologist, John Rock. Soon after the introduction of the first pills, some nasty and life-threatening side effects emerged, which were due to the high doses of sex steroids. This led to the development of new preparations with reduced oestrogen content, progestins with more specific action, and alternative administration routes. Almost every decade we have witnessed a breakthrough in oral contraception. Social and moral objections to birth control have gradually disappeared and, notwithstanding some pill scares, oral contraceptives are now one of the most used methods of contraception. Finally, all's well that ends well: recent reports have substantiated the multiple noncontraceptive health benefits paving the way for a bright future for this 50-year-old product.

Functional cerebral asymmetries (FCAs) are known to fluctuate across the menstrual cycle. The visual line-bisection task administered to normally cycling women showed different patterns of the interhemispheric interactions during menses and the midluteal cycle phase. However, the contribution of estrogens and progestins hormones to this phenomenon is still unclear. The aim of our study was to show a variation of FCAs in women administered oral contraceptives (OCs) using the visual line-bisection task. Visual line-bisection task with three horizontal lines was administered to 36 healthy women taking a 21-day OC. Twenty-nine patients were right handed. The task was administered during OC intake (day 10) and at the end of the pill-free period. The right-handed women showed a significant leftward bias of veridical center on the first and third lines during OC intake compared with an opposite rightward bias during the pill-free period. The same phenomenon of contralateral deviation was observed in left-handed women on day 10 of OC intake. The results of this study confirm a hormonal modulation on interhemispheric interaction and suggest that OCs may improve the interhemispheric interaction reducing FCAs compared with the low hormone level period. This opens new insights in OC prescription and choice of administration schedule in order to improve cognitive performances. Copyright © 2011 Elsevier Inc. All rights reserved.

A sample of 139 predominantly black, young, low-income patients who had accepted oral contraception at a publicly supported family planning clinic has been analyzed for correlates of oral contraception continuation. Interviews were conducted 10-12 months after the clinic visit; at this time 38% of the patients continued taking oral contraceptives. It was found that patients with the highest continuation rates were 18-24 years old, in the 2-3 parity group, living with their husbands, had low-parity mothers, and were able to fill prescriptions in less time with more convenient methods of transportation. Discontinuers tended to have high-parity mothers, live with parents or head their own households, and to be in the 13-17 or 25-45 year old age groups. Fear of long-term use of oral contraceptives and perceived side effects appeared to be implicated in discontinuation. The rate of discontinuation may be associated with irregular coital experience and less consistent exposure to pregnancy.

Combined oral contraceptive (COC) use has been associated with venous thrombosis (VT) (i.e., deep venous thrombosis and pulmonary embolism). The VT risk has been evaluated for many estrogen doses and progestagen types contained in COC but no comprehensive comparison involving commonly used COC is available. To provide a comprehensive overview of the risk of venous thrombosis in women using different combined oral contraceptives. Electronic databases (Pubmed, Embase, Web of Science, Cochrane, CINAHL, Academic Search Premier and ScienceDirect) were searched in 22 April 2013 for eligible studies, without language restrictions. We selected studies including healthy women taking COC with VT as outcome. The primary outcome of interest was a fatal or non-fatal first event of venous thrombosis with the main focus on deep venous thrombosis or pulmonary embolism. Publications with at least 10 events in total were eligible. The network meta-analysis was performed using an extension of frequentist random effects models for mixed multiple treatment comparisons. Unadjusted relative risks with 95% confidence intervals were reported.Two independent reviewers extracted data from selected studies. 3110 publications were retrieved through a search strategy; 25 publications reporting on 26 studies were included. Incidence of venous thrombosis in non-users from two included cohorts was 0.19 and 0.37 per 1 000 person years, in line with previously reported incidences of 0,16 per 1 000 person years. Use of combined oral contraceptives increased the risk of venous thrombosis compared with non-use (relative risk 3.5, 95% confidence interval 2.9 to 4.3). The relative risk of venous thrombosis for combined oral contraceptives with 30-35 μg ethinylestradiol and gestodene, desogestrel, cyproterone acetate, or drospirenone were similar and about 50-80% higher than for combined oral contraceptives with levonorgestrel. A dose related effect of ethinylestradiol was observed for gestodene

Full Text Available Anne Burke Johns Hopkins University School of Medicine, Baltimore, MD, USAAbstract: Oral contraceptives remain a popular method of contraception over 50 years after their introduction. While safe and effective for many women, the failure rate of oral contraception is about 8%. Concerns about the risk of venous thromboembolism continue to drive the search for the safest oral contraceptive formulations. The oral contraceptive NOMAC-E2 contains nomegestrol acetate (NOMAC 2.5 mg + 17b-estradiol (E2 1.5 mg. The approved dosing regimen is 24 days of active hormone, followed by a 4-day hormone-free interval. NOMAC is a progestin derived from testosterone, which has high bioavailability, rapid absorption, and a long half-life. Estradiol, though it has a lower bioavailability, has been successfully combined with NOMAC in a monophasic oral contraceptive. Two recently published randomized controlled trials demonstrate that NOMAC-E2 is an effective contraceptive, with a Pearl Index less than one pregnancy per 100 woman-years. The bleeding pattern on NOMAC-E2 is characterized by fewer bleeding/spotting days, shorter withdrawal bleeds, and a higher incidence of amenorrhea than the comparator oral contraceptive containing drospirenone and ethinyl estradiol. The adverse event profile appears to be acceptable. Few severe adverse events were reported in the randomized controlled trials. The most common adverse events were irregular bleeding, acne, and weight gain. Preliminary studies suggest that NOMAC-E2 does not seem to have negative effects on hemostatic and metabolic parameters. While no one oral contraceptive formulation is likely to be the optimum choice for all women, NOMAC-E2 is a formulation with effectiveness comparable with that of other oral contraceptives, and a reassuring safety profile.Keywords: oral contraception, nomegestrol acetate, estradiol

A modified rational decision model incorporating salient events and social influences (particularly from sexual partners) is used to analyze adolescent women's consistent use of oral contraceptives (OCs) over a six-month period. Data are taken from a panel study of 308 clients of an inner-city family planning clinic. Expected OC use was computed for each subject on the basis of subjective expected utility (SEU) theory, and is found in multivariate analyses to be a significant predictor of actual OC use. In addition, variables representing baseline and follow-up partner influences, the salience of pregnancy for the subject, and positive side effects of OCs during the first months of use are found to predict OC use. Partner's support of OC use during follow-up and positive side effects of OCs are found to predict OC use among subjects for whom OC use was not the expected decision according to baseline SEU. Implications of the findings for models of adolescents' contraceptive behavior and for clinicians are discussed.

Oral contraceptive (OC) use influences the hemostatic system significantly and is a risk factor for development of cardiovascular disease. Factor VII-activating protease (FSAP) has potential effects on hemostasis. The 1601GA genotype of the 1601G/A polymorphism in the FSAP gene expresses a FSAP...... progestins. FSAP genotypes, FSAP and factor VII (FVII) plasma measures were assessed at baseline and after 6 cycles of OC. The 1601GA genotype was present in 49 (8.3%) of the women and was associated with significantly reduced levels of FSAP (P=0.001). OC use increased FSAP antigen by 25% and FSAP activity...

The combined oral contraceptive containing ethinylestradiol and the selective progestogen, desogestrel, in a phasic regimen (DSG-OC, Tri-merci) has been shown to reduce facial oiliness. This study was designed to evaluate further the effects of this OC on the skin of women with facial seborrhea and mild or moderate acne. This was an open, noncomparative, bicenter study in 60 healthy Russian women, aged 18-30 years, with facial seborrhea and mild or moderate facial acne, who wished to use oral contraception. All women received the OC containing desogestrel (50/100/150 microg) and ethinylestradiol (35/30/30 microg) for three phases of 7 days followed by a 7-day pill-free interval, for six cycles. Seborrhea was assessed using the Sebutape technique, in which strips of adhesive microporous polymeric film pressed onto facial sites are used to assess sebaceous activity. Acne was assessed by counting facial lesions. Subjective evaluations of skin and hair condition, patients' feelings to them and satisfaction with the OC were made using a visual analogue scale (VAS). Assessments were made at baseline, and after one, three and six treatment cycles. Sebutape assessments of seborrhea were significantly improved, on the right and left cheeks, after one treatment cycle, and on the forehead after three treatment cycles. These improvements increased steadily and were much larger at the end of Cycle 6. Acne grades were significantly improved after three and six treatment cycles. VAS scores in response to questions dealing with self-esteem and self-confidence were significantly improved after three cycles and in some cases after just one cycle. The women's views of their skin and hair (greasiness) were correspondingly significantly improved. Subjective assessments indicated that after one, three and six cycles, 69%, 93% and 98%, respectively, of women were satisfied or very satisfied with the DSG-OC. In women with facial seborrhea and mild or moderate acne, the use of DSG-OC

Full Text Available Introduction: Oral contraceptives (OCs are considered as one of the most common risk factor of venous thromboembolism (VTE in child bearing age. Some of the recent researches indicate that the odds of VTE may be even higher with newer generations of OCs. The present meta-analysis was designed to evaluate the effect of different generation of OCs on the occurrence of VTE. Methods: Two researchers independently ran a thorough search in Pubmed, ISI Web of Science, EMBASE, CINAHL and Scopus databases regarding study keywords including thromboembolic event, thromboembolism, embolism, thromboembolic, thrombotic and thrombosis, combined with oral contraceptive. The outcomes were the incidence of diagnosed thromboembolism, such as deep vein thrombosis, pulmonary embolism and cerebral venous thrombosis. Based on the heterogeneity of the studies, random effect model was used and pooled odds ratio was reported. Results: Three cohort and 17 case-control studies with 13,265,228 subjects were entered into meta-analysis. Analysis showed that the odds of VTE in women taking OCs are more than three-fold (OR=3.13; 95% CI: 2.61-3.65. The risk of VTE in women taking first-, second- and third-generation OCs are 3.5 fold (OR=3.48; 95% CI: 2.01-4.94, 3 fold (OR=3.08; 95% CI: 2.43-3.74 and 4.3 fold (OR=4.35; CI: 3.69‒5.01, respectively. Conclusion: It seems that the risk of VTE is not same between different generations of OCs, so that third-generation has highest risk. Taking second and third-generation OCs increases the risk of VTE up to 3 and 4.3 fold, respectively. The researchers of the present study suggest that more clinical trials be designed in relation to the effect of newer generations of OCs in different communities. 

Gender and oral contraceptive steroids as determinants of drug glucuronidation: effects on clofibric acid elimination.

Science.gov (United States)

Miners, J O; Robson, R A; Birkett, D J

1984-01-01

The disposition of clofibric acid, a drug metabolised largely by glucuronidation, was studied in eight males, eight females and eight females receiving oral contraceptive steroids (OCS). Clofibric acid plasma clearance was not significantly different in males compared to the control female group but was 48% greater (P less than 0.01) in women receiving OCS compared to non-pill using females. This difference was due to an alteration in clofibric acid metabolic clearance as there were no differences between the groups in clofibric acid free fraction. Along with previous data the results suggest that induction of drug glucuronidation by OCS may be of clinical importance, although any sex-related differences are unlikely to be of clinical significance.

Approach to the patient: contraception in women with polycystic ovary syndrome.

Science.gov (United States)

Yildiz, Bulent O

2015-03-01

Polycystic ovary syndrome (PCOS) is a common reproductive and metabolic disorder. Patients with PCOS present with clinical signs of androgen excess (ie, hirsutism and acne), menstrual irregularities, and infertility. Combined oral contraceptive (OC) pills are the first-line medical therapy for the long-term management of PCOS. Containing a combination of estrogen and progestin, OCs restore regular menses, improve androgen excess, and provide effective contraception and protection from endometrial cancer. The benefits of hormonal contraception outweigh the risks in the vast majority of women with PCOS. However, concerns have been raised about potential adverse cardiovascular and metabolic effects of OCs. Currently available evidence indicates an increased relative risk of venous thrombosis associated with OCs varying among different formulations. Arterial thrombosis risk attributable to OCs does not appear to be significantly increased in young nonsmoking women. OC use might be associated with increased risk of diabetes in morbidly obese women with PCOS with severe insulin resistance. A tailored clinical approach to oral contraception in women with PCOS requires individualized risk stratification and management by determination of each PCOS patient's personal cardiometabolic risk profile at baseline and during follow-up. Before prescribing an OC, clinicians should document individual risk factors including age, smoking, obesity, any degree of glucose intolerance including prediabetes and diabetes, hypertension, dyslipidemia, thrombophilia, and personal or family history of a venous thromboembolic event.

Full Text Available Abstract Background Fertile women may be encouraged to use contraception during clinical trials to avoid potential drug effects on fetuses. However, hormonal contraception interferes with pharmacokinetics and pharmacodynamics and modifies internal milieus. Macrophages depend on the milieu to which they are exposed. Therefore, we assessed whether macrophage function would be affected by the use of combined oral contraceptives (OCs and if this influence depended on the androgenic or non-androgenic properties of progestin. Methods Healthy adult women were enrolled and stratified into two groups: women who did not use OCs (Fs and women treated with OCs (FOCs. FOCs were further stratified as a function of androgenic (FOCA+ and non-androgenic (FOCA- properties of progestins. Routine hematological, biochemical, inflammatory and endothelial dysfunction parameters were measured. Monocyte-derived macrophages (MDMs were evaluated for the expression and activity of estrogen receptors and androgen receptors, and release of tumor necrosis factor α (TNFα was measured from unstimulated and lipopolysaccharide-stimulated cells. Results As is already known, the use of OCs changed numerous parameters: the number of lymphocytes, iron levels, total iron-binding capacity of transferrin, triglycerides, high-density lipoprotein, total cholesterol, and C-reactive protein increased, while prothrombin time and alkaline phosphatase decreased. Hormonal levels also varied: cortisol was higher in FOCs, while luteinizing hormone, follicle-stimulating hormone, and testosterone were lower in FOCs. Asymmetric dimethylarginine, an index of endothelial function, was lower in FOC than in Fs, as were cysteine and bilirubin. The androgenic properties of progestins affected the activity of OCs: in particular, white blood cell count, hemoglobin, high-density lipoprotein and calcium were higher in FOCA- than in FOCA+, whereas percentage oxygen saturation and γ-glutamyl transpeptidase

Full Text Available Jerry KL Tan1, Chemanthi Ediriweera21University of Western Ontario and Windsor Clinical Research Inc., Windsor, Ontario, Canada; 2University of Western Ontario, Southwest Ontario Medical Education Network, Windsor, Ontario, CanadaAbstract: Acne is a common disorder affecting the majority of adolescents and often extends into adulthood. The central pathophysiological feature of acne is increased androgenic stimulation and/or end-organ sensitivity of pilosebaceous units leading to sebum hypersecretion and infundibular hyperkeratinization. These events lead to Propionibacterium acnes proliferation and subsequent inflammation. Hormonal therapy, including combined oral contraceptives (OCs, can attenuate the proximate androgenic trigger of this sequence. For many women, hormonal therapy is a rational option for acne treatment as it may be useful across the spectrum of severity. Drospirenone (DRSP is a unique progestin structurally related to spironolactone with progestogenic, antimineralocorticoid, and antiandrogenic properties. It is available in 2 combined OC preparations (30 µg EE/3 mg DRSP; Yasmin® in a 21/7 regimen; and 20 µg EE/3 mg DRSP; Yaz® in a 24/4 regimen. These preparations are bereft of the fluid retentional side effects typical of other progestins and their safety has been demonstrated in large epidemiological studies in which no increased risk of vascular thromboembolic disease or arrhythmias was observed. In acne, the efficacy of DRSP-containing OCs has been shown in placebo-controlled superiority trials and in active-comparator non-inferiority trials.Keywords: acne vulgaris, combined oral contraceptives, drosperinone, ethinyl estradiol, efficacy, safety, treatment

Although oral contraceptives (OCs) are one the most widespread therapy in young polycystic ovary syndrome (PCOS) women and physical exercise represents a crucial first step in the treatment of overweight and obese PCOS, no studies were performed to compare the effects on cardiovascular risk (CVR) of OCs and physical exercise in PCOS. To compare the effects of OCs administration and physical exercise on the CVR, clinical, hormonal and metabolic parameters in PCOS women. One hundred and fifty PCOS women were enrolled and were randomized to OCs (3 mg drospirenone plus 30 μg ethinyloestradiol), structured exercise training programme (SETP) or polyvitamin tablets. The intervention phase study was of 6 months. Primary outcome was intima-media thickness (IMT) and flow-mediated dilation (FMD). Secondary outcomes were clinical, hormonal and metabolic changes. A significant reduction of IMT and a significant increase of FMD were observed in the SETP group after treatment. Compared to baseline, in the SETP group, a significant improvement in anthropometric measures, insulin sensitivity indexes, lipid profile, cardiopulmonary function, inflammatory markers and frequency of menses was observed. Oral contraceptives use was associated with a significant decrease of hyperandrogenism and a significant improvement of frequency of menses. Further, OCs use had a neutral effect on CVR risk factors. OCs effectively treat hyperandrogenism and menstrual disturbances, while SETP is more effective in improving cardiometabolic profile and cardiopulmonary function in PCOS . © 2016 John Wiley & Sons Ltd.

Oral contraceptive (OC) users typically show a blunted or no cortisol response to psychosocial stress. Although most OC regimens include both an inactive (dummy) and active pill phase, studies have not systematically investigated cortisol responses during these pill phases. Further, high levels of cortisol following a stressor diminish retrieval of emotional material, but the effects of stress on memory among OC users are poorly understood. We examined the effects of a psychosocial stressor, the Trier Social Stress Test, vs. a control condition on cortisol responsivity and emotional memory retrieval in women tested either during their active (n = 18) or inactive pill phase (n = 21). In secondary analyses, we quantitatively compared OC users with normally cycling women and showed a significant lack of cortisol response during both active and inactive pill phase. Emotional recall did not differ between active and inactive pill phases. Stress differentially diminished recall of negative words compared with positive or neutral words, but cortisol levels were unrelated to memory performance. These findings indicate that OC users have distinct cortisol and memory responses to stress that are similar between the active and inactive pill phases. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

There are known sex differences in blood pressure regulation. The differences are related to ovarian hormones that influence β-adrenergic receptors and the transduction of muscle sympathetic nerve activity. Oral contraceptives (OC) modulate the ovarian hormonal profile in women and therefore may alter the cardiovascular response. We questioned if OC would alter the absolute pressor response to static exercise and influence the day-to-day variability of the response. Healthy men (n = 11) and women (n = 19) completed a familiarization day and 2 experimental testing days. Women were divided into those taking (W-OC, n = 10) and not taking (W-NC, n = 9) OC. Each experimental testing day involved isometric handgripping exercise, at 30% of maximal force, followed by circulatory occlusion to isolate the metaboreflex. Experimental days in men were 7-14 days apart. The first experimental testing in W-OC occurred 2-7 days after the start of the active phase of their OC. Women not taking OC were tested during the early and late follicular phase of the menstrual cycle as determined by commercial ovulation monitor. The increase in mean arterial pressure (MAP) during exercise was significantly lower in W-NC (95 ± 4 mm Hg) compared with men (114 ± 4 mm Hg) and W-OC (111 ± 3 mm Hg) (P < 0.05), with the differences preserved during circulatory occlusion. The rise in MAP was significantly correlated between the 2 testing days in men (r = 0.72, P < 0.01) and W-OC (r = 0.77, P < 0.05), but not in W-NC (r = 0.17, P = 0.67), indicating greater day-to-day variation in W-NC. In conclusion, OC modulate the exercise pressor response in women and minimize day-to-day variability in the exercise metaboreflex.

Over 6% of women become pregnant when taking teratogenic medications, and contraceptive counseling appears to occur at suboptimal rates. Adherence to contraception is an important component in preventing unwanted pregnancy and has not been evaluated in this population. We undertook a pharmacy claims-based analysis to evaluate the degree to which women of childbearing age who receive Category X medications adhere to their oral contraception. We evaluated the prescription medication claims for over 6 million women, age 18-44 years, with prescription benefits administered by a pharmacy benefits manager. Women with 2 or more claims for a Category X medication and 2 or more claims for oral contraception were evaluated in further detail. Adherence to oral contraception was measured by analyzing pharmacy claims. Multivariable logistic regression was performed to identify factors associated with adherence. There were 146,758 women of childbearing age who received Category X medications, of which 26,136 also took oral contraceptive medication. Women who received Category X medications were prescribed oral contraception (18%) at rates similar to others of childbearing age (17%). Women prescribed both Category X and oral contraception demonstrated adherence similar to the overall population. Age, class of Category X medication, number of medications, prescriber's specialty, and ethnicity correlated with lower adherence rates. Despite added risk associated with unintended pregnancy, many women who receive Category X medications have refill patterns suggesting nonadherence to oral contraception. Compared with all women age 18-44 years, women receiving teratogenic medications do not have better adherence to oral contraception. Copyright © 2010 Elsevier Inc. All rights reserved.

Combined oral contraception and obesity are strong predictors of low-grade inflammation in healthy individuals: results from the Danish Blood Donor Study (DBDS.

Directory of Open Access Journals (Sweden)

Cecilie J Sørensen

Full Text Available BACKGROUND: C-reactive protein (CRP is a well-established marker of inflammation. The level of CRP is affected by several lifestyle factors. A slightly increased CRP level, also known as low-grade inflammation (LGI, is associated with increased risk of several diseases, especially cardiovascular disease. The aim of this study was to identify predictors of increased CRP levels in healthy individuals. We therefore assessed CRP in a large cohort of blood donors. METHODS: We measured plasma CRP levels in 15,684 participants from the Danish Blood Donor Study. CRP was measured by a commercial assay. Furthermore, all participants completed a standard questionnaire on smoking status, alcohol consumption, physical activity, diet, and various body measurements. Female participants also reported the use of contraception, childbirth, and menopausal status. The relationship between LGI (defined here as a plasma CRP level between 3 mg/L and 10 mg/L and predictors was explored by multivariable logistic regression analysis. Results were presented as odds ratios (OR with 95% confidence intervals (CI. RESULTS: We found LGI in a total of 1,561 (10.0% participants. LGI was more frequent in women using combined oral contraception (OC (29.9% than in men (6.1% and women not using OC (7.9%. Among premenopausal women, OC was the strongest predictor of LGI (odds ratio = 8.98, p<0.001. Additionally, body mass index (BMI and waist circumference were positively associated with LGI. CONCLUSION: High BMI and abdominal obesity strongly predicted LGI among healthy individuals. However, the most striking finding was the high prevalence of LGI among premenopausal women who used combined oral contraception. Although the significance of CRP as a marker of inflammation is well known, the role of CRP in pathogenesis is still uncertain. The impact of oral contraception on CRP levels should nevertheless be considered when CRP is used in risk assessment.

Menstrual cycle phase and oral contraceptives (OC) use influence mood and cognition and these effects may be moderated by the mineralocorticoid receptor (MR) genotype. The effect of menstrual cycle phase on mood may be increased if participants know that this is the focus of study. We assessed aspects associated with reproductive depression such as mood, interpersonal sensitivity, affect lability and depressive cognitions in MR-genotyped OC-users and naturally cycling (NC) women in a carefully masked design. A homogenous sample of healthy, PMS-free, pre-menopausal MR-genotyped women (n=92) completed online questionnaires eight times during two consecutive cycles. The masking of the research question was successful. OC-users did not differ significantly from NC women in positive and negative affect at the time of assessment, personality characteristics (e.g. neuroticism) or mental and physical health. Both groups reported more shifts in anger in the first cycle week (pemotional blunting effect, which is in line with previous reports on affect-stabilizing effects of OC. Limitations were loss of cases due to irregularities in the menstrual cycle length and possible confounding by the 'survivor effect', since almost all OC-users took OC for more than a year.

Possessing correct therapeutic information on oral contraceptives is an important prerequisite for the provision of sound advice to women who are using these products. This study examines Egyptian pharmacists' knowledge of pharmacotherapeutic aspects of oral contraceptives as well as interest in developing skills in providing counseling on oral contraceptive pills. Community pharmacies throughout Alexandria, Egypt. A cross-sectional survey was self-administered by a random sample of community pharmacists in Alexandria, Egypt. Five multiple choice questions likely to arise when counseling women on oral contraceptives were constructed. Questions covered compatibility with breastfeeding, precautions, health risks and managing missed pills of oral contraceptives. Using ordered logistic regression, a model was estimated to predict pharmacists' interest in developing skills in providing counseling on oral contraceptives. Pharmacists' aggregate scores for knowledge questions and pharmacists' interest in developing skills in providing counseling on oral contraceptive pills. Of the 181 approached pharmacists, 92 % participated. Twenty one pharmacists (13 %) did not know the correct answer to any question, 122 (73 %) answered one-two correctly, 23 (14 %) answered three-four correctly. No pharmacist answered all five questions correctly. For pharmacists' interest in developing skills in providing counseling on oral contraceptives, the percentage values for answers were: not interested at all (10.2 %), slightly interested (27.0 %), somewhat interested (23.4 %), interested (30.0 %) and extremely interested (9.6 %). Pharmacists' interest in developing skills in providing counseling on oral contraceptives was significantly associated with the number of women who requested advice from the pharmacists on oral contraceptives (OR 1.54, CI 1.24-1.91). In terms of the learning method of preference, percentage values for answers were: attending a workshop (4 %), online course (18

The contraceptive pill has been a revolution of the last 40 years. In Italy, however, it is much less widely used than in other countries. Explanations for this phenomenon range from religious implications and customs to misinformation and word-of-mouth communication of negative experiences. The oral contraceptive pill is often used to correct menstrual disorders, leading to poor results and side-effects. Recent advances in oral contraception have led to a substantial reduction in doses and side-effects. Low-dose pills contain minimal doses of progesterones and estrogens and ensure good control of the menstrual cycle. Although reduction of ethinyl estradiol (EE) concentrations has reduced the incidence of negative systemic side effects such as water retention, edema and swollen breasts, the low estrogen dose may be associated with spotting and hypomenorrhea or amenorrhea in the long term, as well as dyspareunia due to reduced vaginal trophism, which may induce women to suspend use of the drug. It is also true that only one type of estrogen is used in the pill, albeit at different doses, whereas the progesterone may differ and in many cases is the cause of common side-effects. The choice of progesterone therefore involves not only its effect on the endometrium in synergy with estrogen, but also possible residual androgenic activity which may have negative metabolic repercussions. Indeed, addition of a progesterone, especially androgen-derived, attenuates the positive metabolic effects of estrogen. Two new monophasic oral contraceptives were recently released. They contain 30 microg (Yasmin) or 20 muicrog (Yasminelle) EE and a new progesterone, drospirenone, derived from spirolactone, which has antiandrogenic and antimineralcorticoid activity similar to endogenous progesterone. Like progesterone, the drospirenone molecule is an aldosterone antagonist and has a natriuretic effect that opposes the sodium retention effect of EE. It may, therefore, help to prevent the

Oral contraceptives (OCs) containing androgenic second and third generation progestins decrease insulin sensitivity (SI). In this study we investigated whether an oral contraceptive containing the anti-androgenic progestin drospirenone (DRSP) still alters SI. Lipid modifications were investigated as well. Eleven young healthy women were allocated to receive for 6 months ethinyl-estradiol (EE) 30μg plus DRSP (3mg). SI and glucose utilization independent of insulin (Sg) was investigated by the minimal model method. Lipid modifications were also analyzed. SI did not vary during EE/DRSP (from 3.72±2.62 to 3.29±2.93; p=0.73). Similarly, values of Sg did not vary (from 0.03±0.02 to 0.032±0.014; p=0.87). An increase was observed in HDL cholesterol (9.4±9.8mg/dl; p=0.05) and triglycerides (46.9±75.1mg/dl; p=0.046), with no modification in LDL cholesterol (-4.64±1.704mg/dl; p=0.6). EE/DRSP does not deteriorate SI. These results are reassuring for the long-term use of this association. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

The lowest-dose, extended-cycle combined oral contraceptive pill with continuous ethinyl estradiol in the United States: a review of the literature on ethinyl estradiol 20 µg/levonorgestrel 100 µg + ethinyl estradiol 10 µg

Full Text Available Sheila Krishnan, Jessica KileyDepartment of Obstetrics and Gynecology, Northwestern University, Chicago, Illinois, USAAbstract: Extended-cycle oral contraceptives (OCs are increasing in popularity in the United States. A new extended-cycle OC that contains the lowest doses of ethinyl estradiol (EE and levonorgestrel (LNG + continuous EE throughout the cycle is now available. It provides 84 days of a low-dose, combined active pill containing levonorgestrel 100 µg and ethinyl estradiol 20 µg. Instead of 7 days of placebo following the active pills, the regimen delivers 7 days of ethinyl estradiol 10 µg. Existing studies reveal a similar efficacy and adverse effect profile compared with other extended-regimen OCs. Specifically, the unscheduled bleeding profile is similar to other extended-cycle OCs and improves with the increase in the duration of use. Although lower daily doses of hormonal exposure have potential benefit, to our knowledge, there are no published studies indicating that this specific regimen offers a lower incidence of hormone-related side effects or adverse events. In summary, this new extended-cycle OC provides patients a low-dose, extended-regimen OC option without sacrificing efficacy or tolerability.Keywords: continuous regimen, ethinyl estradiol, extended cycle, oral contraceptive

Hamstra, Danielle A; De Rover, Mischa; De Rijk, Roel H; Van der Does, Willem

2014-11-01

A possible effect of oral contraceptives on emotion recognition was observed in the context of a clinical trial with a corticosteroid. Users of oral contraceptives detected significantly fewer facial expressions of sadness, anger and disgust than non-users. This was true for trial participants overall as well as for those randomized to placebo. Although it is uncertain whether this is an effect of oral contraceptives or a pre-existing difference, future studies on the effect of interventions should control for the effects of oral contraceptives on emotional and cognitive outcomes.

To develop a model comparing costs of 8 hormonal contraceptives and determine whether acquisition costs for implants and intrauterine devices (IUDs) were offset by decreased pregnancy-related costs over a 3-year time horizon from a managed care perspective. A model was developed to assess the budget impact of branded or generic oral contraceptives (OCs), quarterly intramuscular depot medroxyprogesterone, etonogestrel/ethinyl estradiol vaginal ring, etonogestrel implant, levonorgestrel IUD, norelgestromin/ethinyl estradiol transdermal contraceptive, and ethinyl estradiol/levonorgestrel extended-cycle OC. Major variables included drug costs, typical use failure rates, discontinuation rates, and pregnancy costs. The base case assessed costs for 1000 women initiating each of the hormonal contraceptives. The etonogestrel implant and levonorgestrel IUD resulted in the fewest pregnancies, 63 and 85, respectively, and the least cost, $1.75 million and $2.0 million, respectively. In comparison, generic OC users accounted for a total of 243 pregnancies and $3.4 million in costs. At the end of year 1, costs for the etonogestrel implant ($800,471) and levonorgestrel IUD ($949,721) were already lower than those for generic OCs ($1,146,890). Sensitivity analysis showed that the cost of pregnancies, not product acquisition cost, was the primary cost driver. Higher initial acquisition costs for the etonogestrel implant and levonorgestrel IUD were offset within 1 year by lower contraceptive failure rates and consequent pregnancy costs. Thus, after accounting for typical use failure rates of contraceptive products, the etonogestrel implant and levonorgestrel IUD emerged as the least expensive hormonal contraceptives.

Full Text Available Most studies investigating the impact of oral contraceptives have been performed some years ago, when the level of sexual hormones was greater than the actual formulations. Objective: The aim of this study was to evaluate the effects of current combined oral contraceptives (COC on periodontal tissues, correlating the clinical parameters examined with the total duration of continuous oral contraceptive intake. Material and methods: Twenty-five women (19-35 years old taking combined oral contraceptives for at least 1 year were included in the test group. The control group was composed by 25 patients at the same age range reporting no use of hormone-based contraceptive methods. Clinical parameters investigated included pocket probing depth (PD, clinical attachment level (CAL, sulcular bleeding index (SBI and plaque index (Pl.I. Data were statistically evaluated by unpaired t test, Pearson’s correlation test and Spearman’s correlation test. Results: The test group showed increased PD (2.228±0.011 x 2.154±0.012; p<0.0001 and SBI (0.229±0.006 x 0.148±0.005, p<0.0001 than controls. No significant differences between groups were found in CAL (0.435±0.01 x 0.412±0.01; p=0.11. The control group showed greater Pl.I than the test group (0.206±0.007 x 0.303±0.008; p<0.0001. No correlation between the duration of oral contraceptive intake, age and periodontal parameters was observed. Conclusions: These findings suggest that the use of currently available combined oral contraceptives can influence the periodontal conditions of the patients, independently of the level of plaque accumulation or total duration of medication intake, resulting in increased gingival inflammation.

Out from behind the contraceptive Iron Curtain.

Jacobson, J L

1990-01-01

In the early 1950s, the Soviet Union and several of its Eastern European satellites completed their transition from high to low fertility before the US and Western Europe. They did this even though there were not enough modern contraceptives available to meet the needs of its citizens. As late as 1990, the Soviet Union had no factories manufacturing modern contraceptives. A gynecologist in Poland described domestically produced oral contraceptives (OCs) as being good for horses, but not for humans. The Romanian government under Ceaucescu banned all contraceptives and safe abortion services. Therefore, women relied on abortion as their principal means of birth control, even in Catholic Poland. The legal abortion rates in the Soviet Union and Romania stood at 100/1000 (1985) and 91/1000 (1987) as compared to 18/1000 in Denmark and 13/1000 in France. All too often these abortion were prohibited and occurred under unsafe conditions giving rise to complications and death. Further, the lack of contraceptives in the region precipitated and increase in AIDS and other sexually transmitted diseases. On the other hand, abortion rates were minimalized in Czechoslovakia, East Germany, and Hungary due to the availability of modern contraceptives and reproductive health services. Hungary and East Germany even manufactured OCs. OC use in these 2 nations rated as among the world's highest. East Germany also treated infertility and sexually transmitted diseases. The region experienced a political opening in latecomer 1989. In 1989, IPPF gave approximately 15 million condoms and 3000 monthly OC packets to the Soviet Union to ease the transition. More international assistance for contraceptive supplies and equipment and training to modernize abortion practices is necessary.

In the last decade, global use of contraceptive methods has increased. About 50% of couples of childbearing age use a modern contraceptive method. This evolution and a positive change in attitude towards male contraception has encouraged research in fertility regulation to enlarge and to improve acceptance of the contraceptive mix. Current injectable contraceptives interfere with the menstrual cycle. Research is exploring ways to minimize such secondary effects by reducing the total hormone dose and by changing the way the active product is delivered (e.g., microspheres). An injectable prototype is an analogue of levonorgestrel (HRP 002). A new IUD is made of leather suspended by a nylon suture which has been inserted into the uterine muscle. RU-486, often used to interrupt early pregnancy, is being tested as an oral contraceptive (OC). It inhibits secretion of gonadotropins and ovulation. It holds promise as an OC with no estrogen component. Since it also inhibits endometrial development and thus prevents implantation, it may someday be used for emergency contraception (i.e., postcoital contraception). New contraceptive implants under study include Norplant RII (2 rods of levonorgestrel lasting for 3 years), Implanon (desogestrel), and Capranor (biodegradable implant lasting 2 years). The female condom consists of a flexible polyurethane sheath with a flexible ring at each end. It has the potential to protect against sexually transmitted diseases since it covers the labial lips and is impermeable to HIV. France and Switzerland have both approved its use. It will enter the UK market at the end of the year. Approval for marketing has been sought in the US.

Family Planning for women unable to tolerate oral contraceptives.

Science.gov (United States)

Spellacy, W N

1974-04-08

Should women with a family history of diabetes or myocardial infarcation, or women with abnormal blood glucose or cholesterol levels receive oral contraceptives? There is clear evidence that oral contraceptives can alter both carbohydrate and lipid metabolism in certain women. The lipid alteration is mainly an elevation of the circulating triglyceride levels, and only rarely is cholesterol content altered. It is also clear from extensive research during the past ten years that women who already have subclinical abnormalities, either in their triglyceride levels (family hyperlipoproteinemia) or glucose tolerance, are at great risk for the development of clinical disease while using oral contraceptives. Accordingly, all pharmaceutical firms are required by the Food and Drug Administration to instruct physicians about these problems through the package inserts and other means. Specifically, the physician should be alerted by the patient's history, and then he should use the laboratory to confirm any suspicion of abnormalities of carbohydrate or lipid metabolism. If there is any abnormal blood glucose or triglyceride value, the oral contraceptives should not be prescribed. There are other forms of contraception available for child spacing. Mechanical contraceptives will not aggravate a metabolic disorder. A useful substitute then would be an intrauterine device plus vaginal foam. When the woman has completed her family, she should be all means be offered surgical sterilization as a permanent family planning technique.

Full Text Available The use of combined hormonal contraceptives has been reported to increase the level of C-reactive protein (CRP. We assessed the effect of hormonal contraceptive use on inflammatory cytokines including CRP, monocyte chemotactic protein-1, soluble tumor necrosis factor (sTNF, interleukin-6 (IL-6, and soluble CD40 ligand. We used 79 female subjects (19 to 30 years old who were combined oral contraceptives users (n=29, combined vaginal contraceptive users (n=20, and nonusers (n=30 with CRP values of ≤1 (n=46 or ≥3 (n=33. Information on medical history, physical activities, and dietary and sleeping habits were collected. Both oral and vaginal contraceptive users had higher levels of CRP (P<0.0001, compared to nonusers. Only oral contraceptive users exhibited elevated sCD40L (P<0.01. When comparing the groups with CRP ≤ 1 and CRP ≥ 3, levels of IL-6 and sTNF-RI were positively correlated with CRP among oral contraceptive users. We did not observe the same elevation for other inflammatory biomarkers for the CRP ≥ 3 group among vaginal contraceptive users. The clear cause of elevation in CRP level due to the use of different hormonal contraceptive formulations and methods is not well understood. Longitudinal studies with larger sample size are required to better assess the true cause of CRP elevation among hormonal contraceptive users.

The purpose of the article was to document oral contraceptive (OC) discontinuation and switching in a large number of low- and middle-income countries, and to assess the effects of women's education and reason for use (spacing vs. limitation). An attempt was made to explain intercountry variations. Calendar data from 19 Demographic and Health Surveys conducted between 1999 and 2005 were used. Data were analyzed by single- and multiple-decrement life tables and by Cox proportional hazard model. The probability of stopping OC use within 12 months for reasons that implied dissatisfaction with the method ranged from 15% in Indonesia to over 40% in Bolivia and Peru with a median value of 28%. On average, 35% switched to a modern method within 3 months and 16% to a less effective 'traditional' method. Both education and reason for use were strongly related to the probability of switching to a modern method. Discontinuation was lower and switching higher in countries judged to have strong family planning programs. Both discontinuation of use and inadequate switching to alternative methods are major but neglected problems in the family planning services of many developing countries.

Many couples in the Islamic Republic of Iran rely on coital withdrawal for contraception. The purpose of this cross-sectional study was to use the theory of planned behaviour to explore factors that influence withdrawal users' intent to switch to oral contraception (OC). Participants were 336 sexually active, married women, who were current users of withdrawal and were recruited from 5 public family planning clinics in Tehran. A questionnair included measures of the theory of planned behaviour: attitude (behavioural beliefs, outcome evaluations), subjective norms (normative beliefs, motivation to comply), perceived behaviour control, past behaviour and behavioural intention. Linear regression analyses showed that past behaviour, perceived behaviour control, attitude and subjective norms accounted for the highest percentage of total variance observed for intention to use OC (36%). Beliefs-based family planning education and counsellingshould to be designed for users of the withdrawal method.

There is no data on menstrual cyclicity post oral contraceptive (OC) withdrawal with nonhormonal options in PCOS patients. OC could affect obesity, insulin and gonadotropins factors integral to pathogenesis of PCOS, thereby adversely affecting the HPG axis. Menstrual cycles of PCOS patients were retrospectively studied post OCP. Patients developing regular versus irregular cycles post OC were compared. Forty-eight PCOS patients were followed for an average of 1.9 years post OC. Thirty-six (75%) achieved regular cycles over a period of one year with other nonhormonal options like spironolactone and metformin. Seven patients required no treatment. Patients who continued to have irregular cycles had a longer pre OC cycle length (p PCOS may not require any treatment post OC.

Abstract Delayed‐release dimethyl fumarate (DMF) is an oral therapy for relapsing multiple sclerosis with anti‐inflammatory and neuroprotective properties. This 2‐period crossover study was conducted to evaluate the potential for drug–drug interaction between DMF (240 mg twice daily) and a combined oral contraceptive (OC; norgestimate 250 μg, ethinyl estradiol 35 μg). Forty‐six healthy women were enrolled; 32 completed the study. After the lead‐in period (OC alone), 41 eligible participants were randomized 1:1 to sequence 1 (OC and DMF coadministration in period 1; OC alone in period 2) or sequence 2 (regimens reversed). Mean concentration profiles of plasma norelgestromin (primary metabolite of norgestimate) and ethinyl estradiol were superimposable following OC alone and OC coadministered with DMF, with 90% confidence intervals of geometric mean ratios for area under the plasma concentration–time curve over the dosing interval and peak plasma concentration contained within the 0.8–1.25 range. Low serum progesterone levels during combined treatment confirmed suppression of ovulation. The pharmacokinetics of DMF (measured via its primary active metabolite, monomethyl fumarate) were consistent with historical data when DMF was administered alone. No new safety concerns were identified. These results suggest that norgestimate/ethinyl estradiol–based OCs may be used with DMF without dose modification. PMID:28783872

This work argues that contraceptive education urgently requires a new approach that will take into account the client's sexuality at the time the choice of method is made. Emotional factors such as a conscious or unconscious desire for pregnancy or motherhood, family pressures to produce a grandchild, or shame and distrust of contraception may contribute to contraceptive failure. Methods applied at the time of coitus such as condoms or spermicides may not be appropriate for clients for who contraception is a source of anxiety or guilt. The more effective, noncoital-dependent methods including oral contraceptives (OCs), IUDs, and sterilization may generate anxiety over infertility. Their efficacy may lack appeal for clients who enjoy an element of risk. The practitioner's attitude and knowledge may be further influences on the counseling over method choice. Among reversible methods, OCs are ideal for most women as long as they individually prescribed. OCs may be particularly important to the sexual expression of specific groups such as those over 35 with no risk factors other than age. Low-dose progestin-only OCs may be prescribed for this group, although about 10% of users change methods because of menstrual problems. IUDs are usually successfully used by women who have been carefully selected to exclude contraindications. In some cases the partner may be annoyed by the string, which can be rolled up and pushed out of the way or shortened by the practitioner. IUDs are often the best alternative for women with contraindications to OCs or who tolerate their side effects poorly. Spermicides may cause dermatoses or allergies that cause the woman to avoid intercourse. Some women dislike using spermicides because they must be applied prior to each use. Their bad taste is a disadvantage for some couples. Involving the male partner in application of the spermicide may remove some objections. The Billings or cervical mucus method should be avoided by women with irregular

To compare the response of long-term oral contraceptive users (WomenOC; n = 8) to naturally menstruating women (WomenNM; n = 8) at rest and during exercise in temperate (TEMP; 22 °C) and hot (HEAT; 35 °C) conditions. Participants performed a three-stage cycling trial in each condition at 90, 135, and 180% of lactate threshold 1 (total = 52.5 min). Heart rate (HR) and core temperature (T c ) were recorded continuously, whereas blood pressure (BP), ratings of perceived exertion (RPE), blood lactate [La - ], and skin blood flow (BF sk ) were recorded every 7.5 min. Baseline T c was higher in WomenOC (37.5 ± 0.2, 37.6 ± 0.3 °C) than WomenNM (37.2 ± 0.2, 37.0 ± 0.4 °C) before the TEMP (p = 0.03) and HEAT (p  0.05). BF sk measured in WomenNM plateaued from 7.5 min in the HEAT, whereas BF sk measured in WomenOC increased for 15.0 min (p = 0.02) before plateauing. There were no between-group differences in HR, BP, or blood [La - ] before or throughout either trial (p > 0.05). WomenOC had higher (p ≤ 0.04) RPE values than WomenNM in the HEAT, reporting 8 ± 1 and 6 ± 2 at the end of Stage 3, respectively. WomenOC concluded both trials with a comparable T c to WomenNM, but had a prolonged BF sk response and elevated RPE in the HEAT. Changes to BF sk and RPE observed in women using OC may have implications for exercise tolerance in hot conditions.

A Survey of Teenagers' Attitudes Toward Moving Oral Contraceptives Over the Counter.

Evidence suggests that over-the-counter access to oral contraceptives may help expand use among adult women. Teenagers may particularly benefit from this approach, as they experience disproportionately high rates of unintended pregnancy and face unique challenges accessing contraceptives. However, limited research has explored teenagers' attitudes toward over-the-counter access. In 2014, a sample of 348 females aged 14-17, recruited via Facebook advertisements, participated in an online survey assessing teenagers' attitudes toward over-the-counter access and their understanding of how to use oral contraceptives after reading a prototype over-the-counter product label. Differences by participants' characteristics were assessed in bivariate analyses (Pearson chi-square and Fisher's exact tests for categorical measures, and independent t tests and one-way analyses of variance for continuous measures). Seventy-three percent of participants supported over-the-counter access, and 61% reported that they would likely use oral contraceptives available through this approach. Few subgroup differences were found. Notably, sexually experienced participants were significantly more likely than others both to support this approach (85% vs. 63%) and to be interested in obtaining oral contraceptives this way (77% vs. 48%). Participants understood an average of 7.1 of eight key concepts that the prototype product label was intended to convey; no significant differences were found among subgroups. Over-the-counter access may be a promising approach for providing oral contraceptives to teenagers. Additional research is needed to evaluate whether teenagers can screen themselves for contraindications to oral contraceptive use and correctly use oral contraceptives obtained over the counter.

To compare oral contraceptive (OC) pretreatment plus microdose GnRH-a in flare-up protocol and non-OC microdose GnRH-a in flare-up protocol among poor responder ICSI patients. A retrospective analysis of poor responder ICSI patients. Patients were divided into two groups according to used microdose protocol. Precycle treatment with OC followed by follicular phase administration of 40 microg s.c. leuprolide acetate (LA) every 12 h beginning on after 2 day pill-free period and rFSH administration was begun on the third day of LA administration (OC-Group, n=26). Alternatively on day 2 after menses, patients were administered similar stimulation regime (non-OC Group, n=27). There were no significant differences between groups in the number of oocytes, peak estradiol levels, endometrial thickness, fertilization rates and embryo quality. Implantations and pregnancy rates per embryo transfer were similar. OC pretreatment plus microdose GnRHa in flare-up protocol does not offer advantages over non-OC microdose GnRHa in flare-up protocol among poor responder ICSI patients.

Kierkegaard, A

1985-01-01

The anatomy of the thrombus in acute deep vein thrombosis (DVT) in women using oral contraceptives was studied in 277 reports on DVT received by the Swedish Adverse Drug Reaction Advisory Committee (SADRAC). The study revealed a similarity between the anatomy of DVT in women on oral contraceptives and that of DVT in pregnant women, suggesting a pharmacologic influence of the hormones in the pill on the pathogenesis of DVT in women on oral contraceptives. The anatomy of DVT in women on low-estrogen pills was identical with that of DVT in women on high-estrogen pills, suggesting an identical pharmacologic influence of the two types of pill on the pathogenesis of DVT in women on oral contraceptives.

Experience with oral emergency contraception since the OTC switch in Germany.

Science.gov (United States)

Kiechle, Marion; Neuenfeldt, Miriam

2017-03-01

In March 2015, the oral emergency contraceptives levonorgestrel (LNG) and ulipristal acetate (UPA) were released from prescription-only status in Germany. The main research question is to analyse whether the OTC status of oral emergency contraceptives has an influence on the patterns of use. All information is based on searches for public domain sources on emergency contraception. Searches were made for scientific publications, statistics, and surveys. Due to additional active ingredient properties, UPA is superior to LNG in terms of ovulation-inhibiting effect. Since the OTC switch, demand for oral emergency contraceptives has risen by almost 50%, especially at weekends when sexual encounters and thus contraceptive failures are most frequent. However, the age distribution of the users has not changed as a result of the OTC switch. Doctors still play an important role in advising on emergency contraception after the removal of the prescription-only requirement. Pregnancies despite emergency contraception are terminated in more than half of the cases. In federal states with higher rates of use of the morning-after pill, fewer terminations of pregnancy were performed. As a result of the OTC switch, more women and girls use the morning-after pill after unprotected intercourse and the time between unprotected intercourse and taking the oral emergency contraceptive decreases. This is of great advantage in terms of the mechanism of action. UPA is used more frequently than LNG. Only half of all people aged between 16 and 39 years in Germany are aware of the morning-after pill and 94% of women who had a pregnancy terminated in 2015 did not use any emergency contraception after the unprotected intercourse. In the population, there is still a great need for information and education on contraception and emergency contraception.

Insulin-like growth factor-I (IGF-I) stimulates ovarian androgen production. Insulin-like growth factor binding protein-1 (IGFBP-1) inhibits IGF actions in vitro. To investigate the effect of oral contraceptive (OC) pills, given for 3 months, on serum gonadotropin, androgen, IGF-I, and IGFBP-1 concentrations, and glucose tolerance in seven women with polycystic ovarian disease (PCOD) and in five healthy control subjects. Seven women with PCOD and five healthy control subjects. An oral glucose tolerance test (OGTT) was performed before and after treatment with OC. After treatment with OC, serum luteinizing hormone, androstenedione, and free testosterone levels decreased, and sex hormone-binding globulin concentration increased in the women with PCOD as well as in the control subjects. The cumulative response of serum insulin to OGTT was larger in the women with PCOD than in the control subjects both before and after treatment. Serum IGF-I concentration, which was unchanged during OGTT, decreased from basal level of 326 +/- 70 micrograms/L to 199 +/- 28 micrograms/L after treatment with OC in the women with PCOD, whereas no change was found in the control subjects (from 235 +/- 11 micrograms/L to 226 +/- 11 micrograms/L). Treatment with OC caused an increase of the mean basal IGFBP-1 concentration from 24 +/- 7 micrograms/L to 73 +/- 14 micrograms/L in the women with PCOD. This increase was constant during the OGTT. In the control subjects, treatment with OC did not result in any significant change in IGFBP-1 concentrations (from 44 +/- 11 micrograms/L to 61 +/- 9 micrograms/L). The combination of decreased total IGF-I concentration and increased IGFBP-1 concentration induced by OC may decrease ovarian androgen production in PCOD.

Effects of oral contraceptive agents and sex steroids on carbohydrate metabolism.

Science.gov (United States)

Kalkhoff, R K

1972-01-01

The article offers a general interpretation of the influence of oral contraceptive agents on glucose tolerance, emphasizing comparisons of synthetic sex hormones. Although there are conflicting reports on steroid-induced diabetes in normal women, their glucose curves are often higher when under oral contraceptive treatment, suggesting that oral contraceptives may induce a form of subclinical diabetes melitus that is reversible. Evidence from diabetic women suggests definite deliterious effects from contraceptive administration. Estradiol, estriol, and estrone may improve glucose tolerance in nondiabetic women and reduce insulin requirements in diabetics. Progesterone has little effect on carbohydrate tolerance, as did synthetic progestin. Conjugated equine estrogens (equilenine or Premarin) may provoke mild to moderate deterioration of carbohydrate tolerance. Parenterally administered natural estrogens and orally administered synthetic derivatives appear to differ sharply in their effects. Sex hormones' effects on carbohydrate metabolism likely involve interactions with insulin and endogenous glucocorticoids.

Main aim of this study is to quantify and analyze the utilization and utilization trends of oral hormonal contraceptives in the City of Zagreb, 2008-2010, and to propose potential interventions, if necessary. Data gathered from Zagreb pharmacies were assessed by Anatomical Therapeutic Chemical Classification of drugs and Daily Defined Dose methodology. An alarming decrease in total utilization of hormonal contraceptives by 76% from 2008-2009 was found as the main result of this study. A major decrease by 95.5% in utilization of G03AB04 subgroup, sequential combined oral contraceptives, was noted in the year 2009. The subgroup G03AC0, progesterone-only pill group, showed a stable trend, and it became the most utilized subgroup in 2010, due to the decrease in utilization of both fixed and sequential combined oral contraceptives. Utilization of oral contraceptives in Croatia is not regulated adequately, since such dynamics in utilization can occur unnoticed. Measures need to take place in order to improve this situation. Proposed measures include organized farmacovigilance, prescription based on guidelines, and strict screening for risk factors in women seeking oral contraception. More research is required in Croatia to understand the pattern of utilization of hormonal contraceptives and to find the true cause of decrease in utilization of oral contraceptives.

Efficacy and safety of metformin or oral contraceptives, or both in polycystic ovary syndrome

Full Text Available Young-Mo Yang, Eun Joo Choi College of Pharmacy, Chosun University, Gwangju, South Korea Background: Polycystic ovary syndrome (PCOS is an endocrinopathy that affects approximately 10% of reproductive-aged women throughout their lives. Women with PCOS present with heterogeneous symptoms including ovulatory dysfunction, hyperandrogenism, and polycystic ovaries. Therefore, lifelong individualized management should be considered. Pharmacological agents commonly used to manage the symptoms are metformin and oral contraceptive pills. Although these medications have been beneficial in treating PCOS symptoms, their efficacy and safety are still not entirely elucidated. This study aimed to report the efficacy and safety of metformin, oral contraceptives, or their combination in the treatment of PCOS and to define their specific individual roles.Methods: A literature search of original studies published in PubMed and Scopus was conducted to identify studies comparing metformin with oral contraceptives or evaluating the combination of both in PCOS.  Results: Eight clinical trials involving 313 patients were examined in the review. The intervention dosage of metformin ranged from 1,000 to 2,000 mg/d and that of oral contraceptives was ethinylestradiol 35 µg and cyproterone acetate 2 mg. Lower body mass index was observed with regimens including metformin, but increased body mass index was observed in monotherapy with oral contraceptives. Administration of metformin or oral contraceptives, especially as monotherapy, had a negative effect on lipid profiles. In addition, there are still uncertainties surrounding the effects of metformin or oral contraceptives in the management of insulin level, although they improved total testosterone and sex hormone-binding globulin levels. In the included studies, significant side effects due to metformin or oral contraceptives were not reported.  Conclusion: The clinical trials suggest that metformin or oral

Amygdala reactivity to negative stimuli is influenced by oral contraceptive use.

2015-09-01

The amygdala is a highly interconnected region of the brain that is critically important to emotional processing and affective networks. Previous studies have shown that the response of the amygdala to emotionally arousing stimuli can be modulated by sex hormones. Because oral contraceptive pills dramatically lower circulating sex hormone levels with potent analogs of those hormones, we performed a functional magnetic resonance imaging experiment to measure amygdala reactivity in response to emotional stimuli in women using oral contraceptives, and compared their amygdala reactivity with that of naturally cycling women. Here, we show that women who use oral contraceptive pills have significantly decreased bilateral amygdala reactivity in response to negatively valenced, emotionally arousing stimuli compared with naturally cycling women. We suggest that by modulating amygdala reactivity, oral contraceptive pills may influence behaviors that have previously been shown to be amygdala dependent-in particular, emotional memory. © The Author (2015).

[Emergency oral contraception policy: the Peruvian experience].

Science.gov (United States)

Pretell-Zárate, Eduardo A

2013-07-01

Emergency oral contraception is part of the sexual and reproductive rights of women. In 2001, this health policy was incorporated into the Rules of the National Family Planning Program of the Ministry of Health, primarily to prevent unwanted pregnancy and its serious consequences, induced abortion and the high associated maternal mortality rate, which are major public health problems. Scientific research has confirmed that the main mechanism of action of levonorgestrel, component of emergency oral contraception (EOC) is to inhibit or delay ovulation, preventing fertilization of the egg; additionally, it increases the thickening of the cervical mucus, making the sperm migration more difficult. No study has found endometrial abnormalities that may interfere with the implantation of the fertilized egg or embryo development of an implanted egg. However, despite the support of medical science and legal backing, the EOC is available only to users with economic resources, but its use has not been fully implemented in public sector services, due to obstacles created by groups opposed to contraception under claim of an alleged abortive effect that has already been ruled out scientifically. This article describes the administrative experience and legal confrontations between groups of power that prevent the proper implementation of an emergency contraception policy in Peru.

Most women taking combined oral contraceptives (COCs) are satisfied with their contraceptive method. However, one of the most common reasons reported for discontinuation of combined oral contraceptives (COCs) is mood deterioration. This study aimed to compare effects of the second and third generation oral contraceptive pills on the mood of reproductive women. This randomized, double-blind, controlled clinical trial was conducted in reproductive women at health centers in Tehran, Iran. Participants were randomized into the second and third generation oral contraceptive groups. Positive and negative moods were recorded using positive affect, negative affect scale (PANAS) tools at the end the second and fourth months of the study. Data analysis was carried out using ANOVA and P Values pills. The second generation oral contraceptive pills resulted in a decrease in positive mood (95% CI: 43.39 to 38.32 in second month and 43.39 to 26.05 in four month) and increase in negative mood (95% CI: 14.23 to 22.04 in second month and 14.23 to 32.26 in four month - P pills have a better effect on mood in women in reproductive ages than the second generation pills. It can be recommended as a proper combined oral contraceptive in Iran.

[Hyperplastic changes and oral contraceptives in Anglo-Saxon countries].

Science.gov (United States)

Markuszewski, C

1978-09-18

One of the major problems being researched and studied by the World Health Organization is the incidence of harmful side effects in users of steroid contraceptives. A literature search indicates that Anglo-Saxon countries report alarming hyperplastic changes, particularly in the liver, blood clots, hyperlipidemia leading to high blood pressure, porphyria, atypical leiomyomas and cervical hyperplasia. Currently attention is being focused on the relationship between steroid contraceptives and breast cancer. Fazala and Paffenbarger in their study of 1770 women found such benign changes as fibroadenoma, mastopathia fibrosa cystica and papilloma intraductale. In women who had used oral contraceptives for 2-4 yrs, malignancies were 1.9% to 2.5% more frequent than in non-users; in 6 yrs of use, 11 times greater than in non-users. Estrogens, particularly mestranol has been recognized as being harmful to the liver. Length of usage is a definite factor. Beginning with 1960, relatively frequent occurrences of hepotoma in young women on the pill were noted. Caught at an early stage, peliosis hepatis can be reversed if the patient discontinues the use of contraceptives. In some cases, even after a long interval of 6 months to 10 yrs, the disease continued to develop. Liver cell adenoma in the U. S. occurs 1/500,00 to 1/1,000,000. After 5 to 7 yrs of using oral contraceptives, the chance of developing liver cell adenoma is 5 times greater; after 10 yrs of use, 35 times greater. Hepatomas rupture in 43.4% of cases when the patient had been on a contraceptive, while in only 22.2% in cases of non-users. The literature which the author investigated did not establish a clear proof that the hyperplastic changes discussed were due exclusively to usage of oral contraceptives.

Effects of oral contraceptives on natriuretic peptide levels in women with hypothalamic amenorrhea: a pilot study.

2011-06-30

Natriuretic peptides, which are important regulators of salt handling and blood pressure, are 60%-75% higher in healthy young women than in men, consistent with a gender dimorphism. In this randomized, placebo-controlled study in women with functional hypothalamic amenorrhea, we show that administration of oral contraceptives (OC) increases natriuretic peptide levels and that end-of-study free T levels are inversely associated with amino-terminal pro-B-type natriuretic peptide levels, consistent with the hypothesis that natriuretic peptide levels may be mediated by differences in gonadal steroid concentrations-estrogens (E) or androgens.

Delayed-release dimethyl fumarate (DMF) is an oral therapy for relapsing multiple sclerosis with anti-inflammatory and neuroprotective properties. This 2-period crossover study was conducted to evaluate the potential for drug-drug interaction between DMF (240 mg twice daily) and a combined oral contraceptive (OC; norgestimate 250 μg, ethinyl estradiol 35 μg). Forty-six healthy women were enrolled; 32 completed the study. After the lead-in period (OC alone), 41 eligible participants were randomized 1:1 to sequence 1 (OC and DMF coadministration in period 1; OC alone in period 2) or sequence 2 (regimens reversed). Mean concentration profiles of plasma norelgestromin (primary metabolite of norgestimate) and ethinyl estradiol were superimposable following OC alone and OC coadministered with DMF, with 90% confidence intervals of geometric mean ratios for area under the plasma concentration-time curve over the dosing interval and peak plasma concentration contained within the 0.8-1.25 range. Low serum progesterone levels during combined treatment confirmed suppression of ovulation. The pharmacokinetics of DMF (measured via its primary active metabolite, monomethyl fumarate) were consistent with historical data when DMF was administered alone. No new safety concerns were identified. These results suggest that norgestimate/ethinyl estradiol-based OCs may be used with DMF without dose modification. © 2017, The Authors.

The state of the contraceptive art.

Science.gov (United States)

Tyrer, L B; Duarte, J

1983-01-01

The high failure rates of available contraceptive methods attest to the fact that the present technology is inadequate to meet the needs of many women, and new, safer, and highly effective contraceptive methods must be developed for both the female and the male. Previously, industry was largely responsible for the research and development of many of the currently available contraceptives, but at this time it is less than enthusiastic about carrying out further research because of the time and cost associated with the approval of new drugs. Additionally, because of the medico legal climate that exists today, particularly concerning present contraceptive drugs and devices, pharmaceutical companies are concentrating on developing drugs for the treatent of disease conditions, a less risky area. The US federal government, which currently is the single largest funder in the world of contraceptive and related research, is directing little attention to this particular area. The most obvious obstacles to enhanced federal support is the debate over the federal budget priorities. Other deterring factors include the controversy over abortion which has discouraged efforts to call attention to contraceptive research because of concern that it might result in funding cuts instead of increases. Another factor is the traditional allocation of 40% of National Institute of Health funds to population research and 60% to maternal and child health. An overview of currently available contraceptive methods covers oral contraception (OC), long lasting injectable contraception, IUDs, the condom, vaginal contraceptive sponge, the diagphragm, and fertility awareness techniques. Determining the actual benefits versus the risks of OC has proved difficult. OC has changed considerably since it came into use. The most serious side effects attributed to the OCs involve the cardiovascular system, specifically thromboembolism, stroke, and heart attack. The risk of developing these diseases has

Menstruation and menstrual symptoms are commonly cited barriers to physical activity in women. The delay or avoidance of menstruation through extended oral-contraceptive (OC) regimens may mitigate these barriers, yet information on menstrual-manipulation practices in young physically active women is sparse. The objective of this study was to investigate prevalence of, and reasons for, menstrual manipulation with OCs in recreationally and competitively active women. One hundred ninety-one recreationally active (self-reported moderate to vigorous physical activity 150-300 min/wk) women (age 23 ± 5 y), 160 subelite recreationally active (self-reported moderate to vigorous physical activity >300 min/wk) women (age 23 ± 5 y), and 108 competitive (state-, national- or international-level) female athletes (age 23 ± 4 y) completed a self-administered questionnaire assessing OC-regimen habits and reasons for manipulation of menstruation. The majority (74%) of OC users reported having deliberately manipulated menstruation at least once during the previous year, with 29% reporting having done so at least 4 times. Prevalence of menstrual manipulation (at least once in the previous year) was not different between competitive athletes, subelite recreationally active women, and recreationally active women (77% vs 74% vs 72%; P > .05). The most cited reasons for manipulating menstruation were special events or holidays (rated by 75% as important/very important), convenience (54%), and sport competition (54%). Menstrual manipulation through extended OC regimens is common practice in recreationally and competitively active young women, for a range of reasons relating to convenience that are not limited to physical activity. This strategy may help reduce hormone-related barriers to exercise participation, thereby positively affecting participation and performance.

Oral contraceptive therapy for polycystic ovary disease after chronic gonadotropin-releasing agonist administration. Predictors of continued ovarian suppression.

Elkind-Hirsch, K E; Anania, C; Malinak, R

1996-09-01

To study the beneficial effects of oral contraceptive (OC) therapy following gonadotropin-releasing hormone agonist (GnRH-a) administration in women with polycystic ovary disease (PCOD). Twenty-three hyperandrogenic women (aged 15-39) were randomized into two groups; GnRH-a (depot every 28 days) for six months or combination therapy (GnRH-a plus OC "addback") for six months. Following six months of treatment with either therapy, all patients received OC therapy for at least six months. The hormonal state was evaluated at three-month intervals. Hormone levels of luteinizing hormone (LH), testosterone (T) and free T remained suppressed within the normal range in 11 of 17 patients (65%) during the six months of OC only therapy, while the other six patients showed "escape" from suppression, with the LH, T and free T concentrations rising to pre-GnRH-a treatment levels. Use of OC addback therapy did not potentiate the long-acting therapeutic effect of GnRH-a pretreatment; three of six patients in the escape group were pretreated with combination therapy and three with GnRH-a only. In the majority of women with PCOD, OC therapy following GnRH-a administration was effective in maintaining ovarian androgen suppression. Failure to maintain ovarian suppression in this patient population was associated with higher elevations of baseline free T concentrations.

The association between oral contraceptive (OC) use and acute myocardial infarction (AMI) was established in studies from northern Europe and the USA, which took place during the 1960s and 1970s. Few data are available to quantify the risk worldwide of AMI associated with use of OCs introduced since those early studies. This hospital-based case-control study examined the association between a first AMI and current OC use in women from Africa, Asia, Europe, and Latin America (21 centres). Cases were women aged 20-44 years who had definite or possible AMI (classified by history, electrocardiographic, and cardiac-enzyme criteria), who were admitted to hospital, and who survived for at least 24 h. Up to three hospital controls matched by 5-year age-band were recruited for each of the 368 cases (941 controls). All participants were interviewed while in hospital with the same questionnaire, which included information on medical and personal history, lifetime contraceptive use, and blood-pressure screening before the most recent episode of OC use. Odds ratios compared the risk of AMI in current OC users and in non-users (past users and never-users combined). The overall odds ratio for AMI was 5.01 (95% CI 2.54-9.90) in Europe and 4.78 (2.52-9.07) in the non-European (developing) countries; however, these risk estimates reflect the frequent coexistence of other risk factors among OC users who have AMI. Very few AMIs were identified among women who had no cardiovascular risk factors and who reported that their blood pressure had been checked before OC use; odds ratios associated with OC use in such women were not increased in either Europe or the developing countries. Among OC users who smoked ten or more cigarettes per day, the odds ratios in Europe and in the developing countries were over 20. Similarly, among OC users with a history of hypertension (during pregnancy or at any other time), odds ratios were at least ten in both groups of countries. No consistent

Candidiasis, the infection caused by Candida albicans , is one of the most common infections of the oral cavity in humans. Candidiasis causes irritation and is known for its carcinogenic effects. Thus, it is important to recognize the predisposing factors for this opportunistic infection. Several previous studies have demonstrated an increased frequency of vaginal candidiasis in relation to oral contraceptive consumption. Only a few studies on the relation between oral contraceptives and oral candidiasis have been previously conducted. This study aims to evaluate the possible relation between oral contraceptive pills and oral candidiasis. This analytic, case-control study included 40 non-pregnant women divided into two groups: 20 who used oral contraceptive pills and 20 who did not. The groups were matched according to age, oral health, and past and present medical history. Samples were collected from the tongue's dorsum using a cotton swab and inoculated on CHROMagar culture plates. The frequency of positive cultures and the number of Candida colonies were compared between the two groups using independent t-tests and Mann-Whitney statistical tests with SPSS18 software. The frequency of positive cultures of Candida albicans was higher (P value = 0.03) for the case group. Also, the number of C. albicans and C. krusei was significantly higher for the case group compared to the control group (P value = 0.04, P value = 0.03). The results of the present study demonstrate that oral contraceptives containing estradiol can lead to Candida colonization in the oral cavity. It is recommended that further studies comparing the influence of oral contraceptives on Candida's adherence to the epithelium is highly recommended.

In this study scales and items for the Oral Cancer Quality-of-life Questionnaire (QOL-OC) were designed and the instrument was evaluated. The QOL-OC was developed and modified using the international definition of quality of life (QOL) promulgated by the European Organization for Research and Treatment of Cancer (EORTC) and analysis of the precedent measuring instruments. The contents of each item were determined in the context of the specific characteristics of oral cancer. Two hundred thirteen oral cancer patients were asked to complete both the EORTC core quality of life questionnaire (EORTC QLC-C30) and the QOL-OC. Data collected was used to conduct factor analysis, test-retest reliability, internal consistency, and construct validity. Questionnaire compliance was relatively high. Fourteen of the 213 subjects accepted the same tests after 24 to 48 h demonstrating a high test-retest reliability for all five scales. Overall internal consistency surpasses 0.8. The outcome of the factor analysis coincides substantially with our theoretical conception. Each item shows a higher correlation coefficient within its own scale than the others which indicates high construct validity. QOL-OC demonstrates fairly good statistical reliability, validity, and feasibility. However, further tests and modification are needed to ensure its applicability to the quality-of-life assessment of Chinese oral cancer patients.

The processing of emotional information is affected by menstrual cycle phase and by the use of oral contraceptives (OCs). The stress hormone cortisol is known to affect emotional information processing via the limbic mineralocorticoid receptor (MR). We investigated in an exploratory study whether the MR-genotype moderates the effect of both OC-use and menstrual cycle phase on emotional cognition. Healthy premenopausal volunteers (n=93) of West-European descent completed a battery of emotional cognition tests. Forty-nine participants were OC users and 44 naturally cycling, 21 of whom were tested in the early follicular (EF) and 23 in the mid-luteal (ML) phase of the menstrual cycle. In MR-haplotype 1/3 carriers, ML women gambled more than EF women when their risk to lose was relatively small. In MR-haplotype 2, ML women gambled more than EF women, regardless of their odds of winning. OC-users with MR-haplotype 1/3 recognised fewer facial expressions than ML women with MR-haplotype 1/3. MR-haplotype 1/3 carriers may be more sensitive to the influence of their female hormonal status. MR-haplotype 2 carriers showed more risky decision-making. As this may reflect optimistic expectations, this finding may support previous observations in female carriers of MR-haplotype 2 in a naturalistic cohort study. © The Author(s) 2016.

There is increasing support among stakeholders in the United States to make oral contraceptives (OCs) available over the counter (OTC). Previous research on the topic has focused on representative samples of U.S. women, Latina women, low-income women, and abortion clients. However, little is known about the perspectives of African American women, Asian American women, and young women. We conducted 14 focus group discussions with 138 women. Twenty-three percent of participants were ages 18 or younger, 61% were African American, and 26% were Asian American/Pacific Islander. Community organizations recruited participants through convenience sampling and hosted the discussions. Focus groups were transcribed and coded thematically. Women reported potential benefits of OTC access, including convenience and privacy. Many believed OTC availability of OCs would help to reduce unintended pregnancy and help to destigmatize birth control. Participants also expressed concerns about OTC access, such as worry that first-time users and young adolescents would not have enough information to use the pill safely and effectively, as well as concerns about whether women would still obtain preventive screenings. Women were also worried that the cost of OTC OCs would be higher if insurance no longer covered them. Overall, women were interested in the option of obtaining the pill OTC. Future research and advocacy efforts should explore women's concerns, including whether adolescents can effectively use OTC pills and ensuring insurance coverage for OTC contraception.

This article presents an overview of four studies that evaluated a continuous oral contraceptive (OC) containing levonorgestrel (90 mcg) and ethinyl estradiol (20 mcg; LNG/EE) for managing premenstrual dysphoric disorder (PMDD) and premenstrual syndrome (PMS). Three randomized, double-blind, placebo-controlled trials and one open-label, single-treatment substudy examined mean changes from baseline in the Daily Record of Severity of Problems (DRSP) or Penn Daily Symptom Rating (DSR). Improvements from baseline in mean DRSP and DSR scores were observed, but results were not consistent among the studies. Mean percent improvement of premenstrual symptoms ranged from 30% to 59% in controlled trials and 56% to 81% in an open-label substudy. A large placebo effect was also observed in the placebo-controlled studies. Continuous LNG/EE yielded a favorable safety profile. These data, although not consistent, indicate that continuous LNG/EE may reduce the symptoms of PMDD and PMS, providing an option for women who are appropriate candidates for a continuous OC as a contraceptive, the approved indication for this medication.

Kuwabara, Y

1989-01-01

Since the oral contraceptive guideline was issued in April 1987, Japanese pharmaceutical firms have been asking physicians to perform clinical studies of the low-dose OCs. At present, eight products from six companies are under clinical development. Ethinyl estradiol (30-35 micrograms per tablet) as an estrogen component is common to all the test drugs. The progestin component in each OC is norethindrone, levonorgestrel, or desogestrel. Phase I clinical studies on small numbers of healthy volunteers showed that they could tolerate the test drugs without any serious complaints. The effects on endocrine systems, including the inhibition of ovulation, were also examined. Pharmacokinetic parameters of active ingredients were comparable to those of Western women, and no substantial difference seemed to exist between Japanese and Western women. As an example, the results of phase I studies of OJK-777 (Ortho-Novum 7/7/7) are mentioned. Phase III clinical studies, which are "open studies," are now under progress with more than 3,000 women. The major objectives are to examine (1) how well the drugs are tolerated, and the dropout rates; (2) the effects on cycle control, especially bleeding patterns; (3) effects on the cardiovascular system, including coagulation and lipid metabolism; (4) effects on hormone secretions. Although some women have been taking the test drugs for more than 12 cycles, overall statistics are not yet available, because the guideline requires long-term administration (for more than 24 cycles). However, some characteristic features observed thus far are discussed.

[The efficiency of oral contraception containing drospirenone in treating symptoms of premenstrual syndrome or premenstrual dysphoric disorder in gyneacology practice].

The efficiency of oral contraception containing drospirenone in treating symptoms of premenstrual dysphoric disorder (PMDD) was demonstrated in a number of studies. The objective of this observation was to use the "Premenstrual Symptoms Screening Tool" (PSST) to identify women who suffer from severe premenstrual syndrome (PMS) or PMDD and evaluate the benefits of their treatment through using the oral contraceptive containing drospirenone in regime 24/4 in gyneacology practice. The retrospective study was conducted from September 2008 to August 2009. Fifty-one women met by the PSST (Premenstrual Symptoms Screening Tool, Steiner et. al., 2003) the criteria of severe PMS/PMDD. Twenty-eight women took no contraception at the start of the evaluation and twenty-three already took oral contraceptives before changing to the oral contraceptive with drospirenone. The women completed the PSST and in the case of severe PMS/PMDD started treatment with the oral contraceptive containing 20 microg ethinylestradiol /EE/ + 3 mg drospirenone /drsp/ in regime 24/4. The next evaluation was conducted by the same PSST after 3 or 4 months of treatment with this oral contraceptive. The study involved 51 women between the ages of 15 and 44 years (average 25.7 years), who completed the PSST before and after 3 or 4 months of treatment with the oral contraceptive containing drospirenone. The summary score of all subjects significantly decreased from 24.6 before they started using the oral contraceptive with drospirenone to 7,2 after 3 or 4 months of treatment with this oral contraceptive. Significant declines in summary scores have been shown in both groups (in the group without oral contraception from 24.9 at the start of the observation to 8.2 after 3 or 4 months of using this oral contraceptive with drospirenone; and from 24.3 to 6.0 in the group with the change from using various oral contraceptives to using the contraceptive containing drospirenone).

We examined the response of bone turnover markers and indices of energy status after 2 weeks of oral contraceptive (OC) therapy in premenopausal women with exercise-associated menstrual disturbances (EAMD). Six women with EAMD received one 28-day cycle of a triphasic OC containing 180-250 mcg norgestimate/25 mcg ethinyl estradiol (EAMD+OC) and six were controls (EAMD controls). Bone turnover markers amino-terminal propeptide of Type I procollagen and serum carboxy-terminal telopeptides of Type I collagen (PINP and SCTX-I) were assessed at baseline and after 2 weeks of OC therapy (EAMD+OC) or after a 30-day monitoring period (EAMD controls). Total triiodothyronine, resting energy expenditure (REE) and dietary intake were assessed as secondary end points. The absolute and percent changes from baseline in the primary and secondary outcomes were evaluated using an analysis of covariance, adjusting for baseline values of the corresponding outcome. Compared to EAMD controls, a significant change from baseline was observed in the EAMD+OC group for PINP (mean+/-SEM, 9.9+/-6.1 vs. -33.9+/-9.0 mcg/L; p=.005) and SCTX-I (-0.02+/-0.11 vs. -0.25+/-0.07 ng/mL; p=.017), but not osteoprotegerin (-0.53+/-0.22 vs. 0.20+/-0.44 pmol/L; p=.429) after 2 weeks (14.7+/-0.3 days) of OC therapy. Total triiodothyronine levels were elevated in the EAMD+OC group after therapy compared with EAMD controls (19.7+/-4.1 vs. -8.4+/-4.9 ng/dL; p=.002); however, no differences between groups were observed for the changes in REE or dietary intake. Our data demonstrate that 2 weeks of low-dose OC therapy rapidly reduced markers of bone resorption and formation, without any significant impact on energy status in women with EAMD.

BACKGROUND: Combined oral contraceptive pills were the first contraceptive method to provide sexual freedom of choice for women through reliable, personal and private control of fertility. They are the most widely used hormonal contraceptives and also the most popular non-surgical method of contraception. OBJECTIVE: To review the profile of acceptors of combined oral contraceptive pills at the University of Uyo Teaching Hospital, Uyo. METHODOLOGY: An 8 year review of all clients that accepted combined oral contraceptive pills in the family planning clinic. RESULTS: There were 1,146 new contraceptive acceptors during the period of study out of which 309 (27.9%) accepted the pills. Majority of the clients were between 20 and 29 years of age (54.0%), were multiparous (72.8%), Christians (99.7%) and 61.2% had tertiary level education. Two hundred and fifty-five women (82.5%) desired to use combined oral contraceptive pills to space births while 7.8% wanted to limit child bearing. There was a high discontinuation rate among the women (45.0%) and out of these 87.9% of the clients changed to other contraceptive methods. All the clients commenced their pills within seven days of menstruation and only the low dose monophasic preparations were available in the family planning unit and thus were given to the clients. CONCLUSION: Women who accept to initiate combined oral contraceptive pills in our center are young, well educated, multiparous women who want to space their pregnancies. However, due to the high discontinuation rate among the clients, there is need for further studies evaluating reasons for the high discontinuation rate, exploring interactions between clients and providers' and also providers' attitude towards combined pills in our environment.

The impact of combined oral contraceptives on ocular tissues: a review of ocular effects

Directory of Open Access Journals (Sweden)

Marilita M. Moschos

2017-10-01

Full Text Available The aim of this manuscript is to review the action and adverse effects of combined oral contraceptives (COCs on ocular tissues. The percentage of unwanted pregnancies and the subsequent abortions make contraception crucial worldwide. Over 100 million women around the world use common contraceptive methods, including intrauterine devices, combined estrogen and progestin oral contraceptives, as well as progestin only preparations (oral contraceptives, implants or injections. COCs are widely used for contraception, but they are also indicated in menorrhagia, endometriosis, acne and hirsutism, fibroid uterus and premenstrual syndrome. However, they have been associated with high rates of cardiovascular events, venous thromboembolic disease, ischemic strokes and breast cancer. The incidence of COCs-related ocular complications is estimated to be 1 in 230 000, including dry eye symptoms, corneal edema, lens opacities and retinal neuro-ophthalmologic or vascular complications. We may infer that the serious ocular complications of COCs can be prevented by eliminating the estrogen dosage and choosing third-generation progestins. In any case, doctors should take into consideration the systemic and ocular history of the patients before selecting any method of contraception.

The role of combined oral contraceptives in the management of acne and seborrhea.

Science.gov (United States)

del Marmol, V; Teichmann, A; Gertsen, K

2004-06-01

Acne and seborrhea (or facial oiliness) are related androgenic skin disorders which affect a high proportion of women after menarche. They can have a negative effect on psychological well-being and social life. Androgens play an important role in the pathogenesis of acne through the stimulation of sebum secretion, increasing sebaceous gland size and possibly through follicular hyperkeratinization. Conversely, estrogens decrease sebum production by suppressing gonadotropin release and androgen production and increasing sex hormone binding globulin production. One of the treatment options for these conditions is hormonal therapy, especially for women who require contraception. The effect of combined oral contraceptives in androgenic skin disorders depends on their estrogen:progestogen balance and on the antiestrogenic activity of the progestogen component. Improved understanding of what women value about oral contraceptives suggests that the choice of product should be tailored as much as possible to the individual. Several combined oral contraceptives containing new-generation progestogens (e.g. desogestrel, gestodene) or progestational antiandrogens (e.g. cyproterone acetate, chlormadinone acetate) have demonstrated efficacy in the treatment of women with acne, although comparisons between trials are difficult because of differing endpoints. Seborrhea has been less well studied, but the few studies that are available show an improvement in women with this condition using combined oral contraceptives.

To investigate effects of menopausal status, oral contraceptives (OC), and postmenopausal hormone therapy (HT) on normal breast parenchymal contrast enhancement (CE) and non-mass-like enhancing areas in magnetic resonance mammography (MRM). A total of 459 female volunteers (mean age 49.1 ± 12.5 years) underwent T1-weighted 3D MRM 1-5 min after bolus injection of gadobutrol. Quantitative analysis was performed in normal breast parenchyma by manually tracing regions of interest and calculating percentage CE. Semiquantitative analysis was performed in non-mass-like enhancing areas, and signal intensity changes were characterised by five predefined kinetic curve types. The influence of OC (n = 69) and HT (n = 24) on CE was studied using random effects models. Breast parenchymal enhancement was significantly higher in premenopausal than in postmenopausal women (P < 0.001). CE decreased significantly with the use of OC (P = 0.01), while HT had negligible effects (P = 0.52). Prevalence of kinetic curve types of non-mass-like enhancement differed strongly between pre- and postmenopausal women (P < 0.0001), but was similar in OC users and non-OC users (P = 0.61) as well as HT users and non-HT users (P = 0.77). Normal breast parenchymal enhancement and non-mass-like enhancing areas were strongly affected by menopausal status, while they were not affected by HT use and only moderately by OC use. (orig.)

Bergmann, Julie N; Stockman, Jamila K

2015-06-01

Intimate partner violence (IPV) is estimated to affect 25% of adult women in the United States alone. IPV directly impacts women's ability to use contraception, resulting in many of unintended pregnancies and STIs. This review examines the relationship between IPV and condom and oral contraceptive use within the United States at two levels: the female victim's perspective on barriers to condom and oral contraceptive use, in conjunction with experiencing IPV (Aim 1) and the male perpetrator's perspective regarding condom and oral contraceptive use (Aim 2). We systematically reviewed and synthesized all publications meeting the study criteria published since 1997. We aimed to categorize the results by emerging themes related to each study aim. We identified 42 studies that met our inclusion criteria. We found 37 studies that addressed Aim 1. Within this we identified three themes: violence resulting in reduced condom or oral contraceptive use (n=15); condom or oral contraceptive use negotiation (n=15); which we further categorized as IPV due to condom or oral contraceptive request, perceived violence (or fear) of IPV resulting in decreased condom or oral contraceptive use, and sexual relationship power imbalances decreasing the ability to use condoms or oral contraceptives; and reproductive coercion (n=7). We found 5 studies that addressed Aim 2. Most studies were cross-sectional, limiting the ability to determine causality between IPV and condom or oral contraceptive use; however, most studies did find a positive relationship between IPV and decreased condom or oral contraceptive use. Quantitative, qualitative, and mixed methods research has demonstrated the linkages between female IPV victimization/male IPV perpetration and condom or oral contraceptive use. However, additional qualitative and longitudinal research is needed to improve the understanding of dynamics in relationships with IPV and determine causality between IPV, intermediate variables (e

Metabolic Effects of a Commonly Used Combined Hormonal Oral Contraceptive in Women With and Without Polycystic Ovary Syndrome

Abstract Background: Data on combined hormonal oral contraceptives' (OCs) effects on metabolic changes in women with polycystic ovary syndrome (PCOS) have been conflicting and were predominantly based on OCs with cyproterone acetate (unavailable in the United States) Most studies did not include normal women as controls. We compared metabolic changes before and after an OC commonly used in the United States between women with and without PCOS. Methods: Ten PCOS and 20 control women took ethinyl estradiol 35 μg and norgestimate 0.18/0.215/0.25 mg. Fasting glucose and insulin, area-under-the-curve (AUC) glucose and insulin, insulin sensitivity (homeostatic model assessment of insulin sensitivity index [HOMA-ISI] and Matsuda index), insulinogenic index (Δinsulin0–30 minutes/Δglucose0–30 minutes), blood pressure, and lipids were evaluated at baseline and after three cycles of OC. Results: At baseline, PCOS women had lower insulin sensitivity (Matsuda index p = 0.0093, HOMA-ISI p = 0.0397), higher fasting insulin (p = 0.0495), fasting glucose (p = 0.0393), AUC insulin (p = 0.0023), and triglycerides (p = 0.0044) versus controls. Baseline AUC glucose did not differ between PCOS women and controls. After 3 months of OC use, glucose tolerance worsened in PCOS women versus controls (p = 0.0468). Higher baseline androgens were predictive of worsened glucose tolerance, and a reduction of AUC insulin during OC use. The insulinogenic index significantly decreased in PCOS women (p glucose tolerance (demonstrated by AUC glucose) after 3 months of a commonly used OC compared with control women. Larger studies with longer follow-up should confirm these findings. PMID:26871978

Current Hormonal Contraceptive Use Predicts Female Extra-Pair and Dyadic Sexual Behavior: Evidence Based on Czech National Survey Data

Full Text Available 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: Few studies have examined the risk of an ovarian serous borderline tumor (SBT) associated with parity, infertility, oral contraceptives (OCs), or hormone replacement therapy (HRT), which was the study aim. METHODS: This nationwide case-control study included all women with an SBT...... diagnosis in Denmark, 1978-2002. SBTs were confirmed by centralized expert pathology review. For each case, 15 age-matched female controls were randomly selected using risk-set sampling. Cases and controls with previous cancer (except for non-melanoma skin cancer) and controls with bilateral oophorectomy...... or salpingo-oophorectomy were excluded. Conditional logistic regression was used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: We found a strongly decreased risk of SBTs among parous women which decreased with increasing number of children (p

Impact of hormone-associated resistance to activated protein C on the thrombotic potential of oral contraceptives: a prospective observational study.

Directory of Open Access Journals (Sweden)

Heiko Rühl

Full Text Available The increased thrombotic risk of oral contraceptives (OC has been attributed to various alterations of the hemostatic system, including acquired resistance to activated protein C (APC. To evaluate to what extent OC-associated APC resistance induces a prothrombotic state we monitored plasma levels of thrombin and molecular markers specific for thrombin formation in women starting OC use. Elevated plasma levels of thrombin have been reported to characterize situations of high thrombotic risk such as trauma-induced hypercoagulability, but have not yet been studied during OC use.Blood samples were collected prospectively from healthy women (n = 21 before and during three menstruation cycles after start of OC. APC resistance was evaluated using a thrombin generation-based assay. Plasma levels of thrombin and APC were directly measured using highly sensitive oligonucleotide-based enzyme capture assay (OECA technology. Thrombin generation markers and other hemostasis parameters were measured additionally.All women developed APC resistance as indicated by an increased APC sensitivity ratio compared with baseline after start of OC (p = 0.0003. Simultaneously, plasma levels of thrombin, prothrombin fragment 1+2, and of thrombin-antithrombin complexes did not change, ruling out increased thrombin formation. APC plasma levels were also not influenced by OC use, giving further evidence that increased thrombin formation did not occur.In the majority of OC users no enhanced thrombin formation occurs despite the development of APC resistance. It cannot be ruled out, however, that thrombin formation might occur to a greater extent in the presence of additional risk factors. If this were the case, endogenous thrombin levels might be a potential biomarker candidate to identify women at high thrombotic risk during OC treatment. Large-scale studies are required to assess the value of plasma levels of thrombin as predictors of OC-associated thrombotic risk.

Physical examination prior to initiating hormonal contraception: a systematic review.

Provision of contraception is often linked with physical examination, including clinical breast examination (CBE) and pelvic examination. This review was conducted to evaluate the evidence regarding outcomes among women with and without physical examination prior to initiating hormonal contraceptives. The PubMed database was searched from database inception through March 2012 for all peer-reviewed articles in any language concerning CBE and pelvic examination prior to initiating hormonal contraceptives. The quality of each study was assessed using the United States Preventive Services Task Force grading system. The search did not identify any evidence regarding outcomes among women screened versus not screened with CBE prior to initiation of hormonal contraceptives. The search identified two case-control studies of fair quality which compared women who did or did not undergo pelvic examination prior to initiating oral contraceptives (OCs) or depot medroxyprogesterone acetate (DMPA). No differences in risk factors for cervical neoplasia, incidence of sexually transmitted infections, incidence of abnormal Pap smears or incidence of abnormal wet mount findings were observed. Although women with breast cancer should not use hormonal contraceptives, there is little utility in screening prior to initiation, due to the low incidence of breast cancer and uncertain value of CBE among women of reproductive age. Two fair quality studies demonstrated no differences between women who did or did not undergo pelvic examination prior to initiating OCs or DMPA with respect to risk factors or clinical outcomes. In addition, pelvic examination is not likely to detect any conditions for which hormonal contraceptives would be unsafe. Published by Elsevier Inc.

The literature presents contradictory results regarding the effects of contraceptives on cardiac autonomic regulation. The research team aimed to evaluate the effects of musical auditory stimulation on cardiac autonomic regulation in women who use oral contraceptives. The research team designed a transversal observational pilot study. The setting was the Centro de Estudos do Sistema Nervoso Autônomo (CESNA) in the Departamento de Fonoaudiologia at the Universidade Estadual Paulista (UNESP) in Marília, SP, Brazil. Participants were 22 healthy nonathletic and nonsedentary females, all nonsmokers and aged between 18 and 27 y. Participants were divided into 2 groups: (1) 12 women who were not taking oral contraceptives, the control group; and (2) 10 women who were taking oral contraceptives, the oral contraceptive group. In the first stage, a rest control, the women sat with their earphones turned off for 20 min. After that period, the participants were exposed to 20 min of classical baroque music (ie, "Canon in D Major," Johann Pachelbel), at 63-84 dB. Measurements of the equivalent sound levels were conducted in a soundproof room, and the intervals between consecutive heartbeats (R-R intervals) were recorded, with a sampling rate of 1000 Hz. For calculation of the linear indices, the research team used software to perform an analysis of heart rate variability (HRV). Linear indices of HRV were analyzed in the time domain: (1) the standard deviation of normal-to-normal R-R intervals (SDNN), (2) the root-mean square of differences between adjacent normal R-R intervals in a time interval (RMSSD), and (3) the percentage of adjacent R-R intervals with a difference of duration greater than 50 ms (pNN50). The study also analyzed the frequency domain-low frequency (LF), high frequency (HF), and LF/HF ratio. For the control group, the musical auditory stimulation reduced (1) the SDNN from 52.2 ± 10 ms to 48.4 ± 16 ms (P = .0034); (2) the RMSSD from 45.8 ± 22 ms to 41.2 �

Full Text Available Anita L NelsonObstetrics and Gynecology, David Geffen School of Medicine at UCLA, Harbor UCLA Medical Center, Torrance, California, USAAbstract: Natazia® is a new oral contraceptive with estradiol valerate and dienogest in a unique multiphasic formulation that includes a shortened hormone-free interval. This new formulation has been approved for both contraception and also as a treatment for heavy menstrual bleeding in women who desire to use oral contraceptives as their method of birth control. It is marketed in the US as Natazia® and elsewhere as Qlaira®. This article will review the properties of each of the major new features of this pill: estradiol used in place of ethinyl estradiol, dienogest as the progestin, and the unique dosing pattern of this product. It will also summarize the results of the pivotal clinical trials of contraceptive effectiveness, bleeding patterns, safety and tolerability. The lessons learned from the clinical trials about the effectiveness of this formulation in the treatment of excessive menstrual bleeding will be summarized. Also, results of trials comparing this new pill to other popular formulations for "menstrually-related" symptoms and for potential female sexual dysfunction related to use of oral contraceptives will be presented. This review will suggest how all this information might be used to counsel women about how to use this pill most successfully.Keywords: oral contraceptives, estradiol valerate, dienogest, heavy menstrual bleeding, menorrhagia, dynamic dosing

As oral contraceptive pills are available over the counter in pharmacies, pharmacists are professionally responsible for checking and informing patients about every aspect of taking these drugs. Simulated patient method is a new and robust way to evaluate professional performance of pharmacists. The aim of the present study was to evaluate the pharmacy practice of Iranian pharmacists regarding over-the-counter use of oral contraceptive pills using simulated patient method. Simulated patients visited pharmacy with a prescription containing ciprofloxacin and asked for oral contraceptive pills. The pharmacist was expected to ask important questions for using these drugs and to inform the patient about them properly. Moreover, the Pharmacists should advise patients in regard to the possible interaction. Ninety four pharmacists participated in this study. In 24 (25.3%) visits, the liable pharmacist was not present at the time of purchase. Furthermore, In 13 (18.57 %) visits by the simulated patients, the liable pharmacists did not pay any attention to the simulated patients even when they asked for consultation. Twenty nine (41.43%) pharmacists did not ask any question during dispensing. Nausea was the most frequent described side effect by pharmacists (27 (38.57%)). Yet important adverse effects of oral contraceptive pills were not mentioned by the pharmacists except for few ones. Only twelve (17.14%) pharmacists mentioned the possible interaction. There was a significant relation between the pharmacists' gender and detection of possible interaction (p value= 0.048). The quality of the pharmacists' consultations regarding the over the counter use of oral contraceptive pills was not satisfactory and required improvement.

[Place of persistence trouble during oral contraception and subsequent use of emergency contraception].

Jamin, C; Lachowsky, M

In order to improve the understanding of hormonal contraceptive failures, this study evaluates the persistence of oral contraception and the use of emergency contraception (EC) during persistence incidents. We made the hypothesis of the existence of a strong link between the risk of unplanned pregnancies and these two parameters. In this study, we also evaluated women's perception of EC in order to elucidate the reasons of EC insufficient use. One survey was carried out on Internet on a representative sample of women, aged 16-45. In this survey, 3775 French women were interviewed (source-population). We defined a target population of 2415 fertile women who had heterosexual intercourse during the last 12 months, and a population of 760 women at risk of unintended pregnancy who had unprotected sexual intercourse during the last 12 months(risk-population). A little more than 30% of the target population, meaning 20% of the source-population (n=745) stopped their contraceptive method temporarily for an average time of two months. Almost 60% of women had a risk of unwanted pregnancy during this period without contraception, which is 59% of the risk-population. Only 20% of women among the population at risk used EC. The main reasons given for EC insufficient use were the misperception of the risk of pregnancy, the lack of knowledge about EC and its way of use. For the first time, this survey shows that 13% of women (of the source population) decide to stop temporarily their contraceptive method for an average time of two months per year. Fifty-nine percent of unplanned pregnancy situations are due to this poor contraception persistence. Although there is a need to reduce the risk of women being at risk, it seems also highly desirable to overcome the consequences of this poor persistence. Giving information about EC and a systematic prescription during contraception consultations would lead to an increased use of EC. Copyright © 2014 Elsevier Masson SAS. All rights

In unselected reproductive-aged women, use of combined estrogen-progestin oral contraceptive pills has been linked with an increased risk of vascular disease. The aim of this study was to investigate the effect of oral contraception on cardiometabolic risk factors in a population of women with hyperandrogenism. The study included 16 untreated women with elevated testosterone levels and 15 matched healthy women who were then treated with oral contraceptive pills containing ethinyl estradiol (30μg) and drospirenone (3mg). Plasma lipids, glucose homeostasis markers, circulating levels of androgens, uric acid, high-sensitivity C-reactive protein (hsCRP), fibrinogen and homocysteine, as well as urinary albumin-to-creatinine ratio (UACR) were assessed at baseline and after 12 weeks of treatment. Compared to healthy women, women with elevated androgen levels showed increased plasma levels of hsCRP, fibrinogen and homocysteine, as well as a higher value of UACR. Oral contraception reduced androgen levels only in hyperandrogenic women. In healthy women, ethinyl estradiol plus drospirenone increased plasma levels of insulin, hsCRP, fibrinogen and homocysteine, while in women with elevated androgen levels their effect was limited only to a small increase in hsCRP. Our results suggest that a deteriorating effect of oral contraceptive pills containing ethinyl estradiol and drospirenone in hyperandrogenic women is weaker than in healthy young women and that ethinyl estradiol/drospirenone combination therapy may be safely used in the former group of patients.

Androgens are the main stimulators of sebum production. Androgens originate from the gonads and adrenal glands, but can also be locally produced within the sebaceous gland from dehydroepiandrosterone sulfate. In the presence of high androgen levels, which can be either a normal pattern of adolescence or a consequence of gonadal or adrenal disease, overproduction of sebum triggers the pathogenesis of acne which, mainly in adolescent women, has deleterious psychological consequences. Estrogens exert the opposite action on sebum production, probably due to the reduction of androgen availability, a direct consequence of estrogen-related increased production of hepatic sex hormone-binding globulin (SHBG. The inhibition of the hypothalamus-pituitary axis induced by oral contraceptives is followed by reduced androgen production. Oral contraceptives containing ethinyl estradiol, which has strong estrogenic activity, amplify the hypoandrogenic effect via estrogen-related stimulation of SHBG. The hypoandrogenic effect of oral contraceptives is modulated by the progestin compound. Progestins derived from 19-nortestosterone bind androgenic receptors, whereas others exert antiandrogenic properties by antagonizing the binding of androgens to their receptors, reduce 5α-reductase, and do not bind SHBG. Through this last effect, SHBG is freely

1999-01-01

The influence of menstrual cycle phase and oral contraceptive use on neurobehavioral function and circadian rhythms were studied in healthy young women (n = 25) using a modified constant routine procedure during 24 h of sleep deprivation. Alertness and performance worsened across sleep deprivation and also varied with circadian phase. Entrained circadian rhythms of melatonin and body temperature were evident in women regardless of menstrual phase or oral contraceptive use. No significant difference in melatonin levels, duration, or phase was observed between women in the luteal and follicular phases, whereas oral contraceptives appeared to increase melatonin levels. Temperature levels were higher in the luteal phase and in oral contraceptive users compared to women in the follicular phase. Alertness on the maintenance of wakefulness test and some tests of cognitive performance were poorest for women in the follicular phase especially near the circadian trough of body temperature. These observations suggest that hormonal changes associated with the menstrual cycle and the use of oral contraceptives contribute to changes in nighttime waking neurobehavioral function and temperature level whereas these factors do not appear to affect circadian phase.

Are oral emergency contraceptives a safe and effective form of long-term birth control?

Kraus, Connie; Hooper-Lane, Christopher

Yes, but not as effective as some other methods. Annual pregnancy rates in women using pericoital levonorgestrel 150 mcg to 1 mg range from 4.9% to 8.9%; menstrual irregularity is the most common adverse effect (strength of recommendation [SOR]: B, Cochrane review of lower-quality trials). In women younger than 35 years who have sexual intercourse 6 or fewer times per month, correct and consistent use of pericoital levonorgestrel 1.5 mg results in an annual pregnancy rate of 11% (SOR: B, one large prospective, open-label trial). Pericoital contraception is less effective than long-acting reversible contraceptives (annual pregnancy rates of 0.05%-0.8%) or perfect use of combined oral contraceptives (0.3% annual pregnancy rate), but similar to, or better than, typical use of combined oral contraception (9%) and condoms (18%).

The delivery of combination contraceptive steroids from a transdermal contraceptive patch or a contraceptive vaginal ring offers potential advantages over the traditional oral route. The transdermal patch and vaginal ring could require a lower dose due to increased bioavailability and improved user compliance. To compare the contraceptive effectiveness, cycle control, compliance (adherence), and safety of the contraceptive patch or the vaginal ring versus combination oral contraceptives (COCs). Through February 2013, we searched MEDLINE, POPLINE, CENTRAL, LILACS, ClinicalTrials.gov, and ICTRP for trials of the contraceptive patch or the vaginal ring. Earlier searches also included EMBASE. For the initial review, we contacted known researchers and manufacturers to identify other trials. We considered randomized controlled trials comparing a transdermal contraceptive patch or a contraceptive vaginal ring with a COC. Data were abstracted by two authors and entered into RevMan. For dichotomous variables, the Peto odds ratio (OR) with 95% confidence intervals (CI) was calculated. For continuous variables, the mean difference was computed. We also assessed the quality of evidence for this review. We found 18 trials that met our inclusion criteria. Of six patch studies, five examined the marketed patch containing norelgestromin plus ethinyl estradiol (EE); one studied a patch in development that contains levonorgestrel (LNG) plus EE. Of 12 vaginal ring trials, 11 examined the same marketing ring containing etonogestrel plus EE; one studied a ring being developed that contains nesterone plus EE.Contraceptive effectiveness was not significantly different for the patch or ring versus the comparison COC. Compliance data were limited. Patch users showed better compliance than COC users in three trials. For the norelgestromin plus EE patch, ORs were 2.05 (95% CI 1.83 to 2.29) and 2.76 (95% CI 2.35 to 3.24). In the levonorgestrel plus EE patch report, patch users were less

Only Finnish women currently have access to all three E2-based formulations. E2/NOMAC is currently approved only in Europe, while E2V/DNG is approved globally. To assist clinicians counseling women considering use of one of these formulations, we conducted a review of the published information about the current E2-containing oral contraceptives. A literature search was conducted using the Ovid interface and a combination of free search terms relevant to estradiol and oral contraception to identify suitable articles for inclusion in this review. The available data show that E2V/DNG, E2/NOMAC, and E2V/CPA are all effective oral contraceptives. While direct comparisons are lacking, indirect evidence suggests that E2V/DNG and E2/NOMAC may have better bleeding profiles than E2V/CPA. E2V/DNG is also approved for the treatment of heavy menstrual bleeding. Both E2V/DNG and E2/NOMAC have minimal influence on hemostatic, lipid, and carbohydrate metabolism parameters, or induce less change in these parameters relative to ethinylestradiol-based oral contraceptives. However, the predictive value of these surrogate parameters is a matter of debate, and whether these differences can be translated into meaningful clinical outcomes needs to be established in large-scale, post-marketing, prospective, Phase IV cohort

The occurrence of bi-directional drug interactions between antiepileptic drugs (AEDs) and combined oral contraceptives (M) pose potential risks of unintended pregnancy and as well as seizure deterioration. It is well established that several of the older AEDs (carbamazepine, phenytoin...... AEDs, which undergoes glucuronidation processes, such as valproate and oxcarbazepine, may be affected by OCs. The magnitude of the drug-drug interactions show in general wide inter-individual variability and the change in the elimination rate is often unpredictable and can be influenced by a number...... of co-variants such as co-medication of other drugs, as well as genetic and environmental factors. It is therefore recommended that change in OC use is assisted by AED monitoring whenever possible. (C) 2007 British Epilepsy Association. Published by Elsevier Ltd.

Background Interest is growing in moving oral contraceptives over-the-counter (OTC), although concerns exist about whether women would continue to get preventive health screening. Study Design We recruited cohorts of US-resident women who obtained oral contraceptives from US family planning clinics (n=532) and OTC from pharmacies in Mexico (n=514) and interviewed them four times over 9 months. Based on self-reports of having a Pap smear within 3 years or ever having had a pelvic exam, clinical breast exam and testing for sexually transmitted infections (STIs), we assessed the prevalence of preventive screening using Poisson regression models. Results The prevalence of screening was high for both groups (>88% for Pap smear, pelvic exam and clinical breast exam and >71% for STI screening), while the prevalence ratios for screening were higher for clinic users, even after multivariable adjustment. Conclusions Results suggest that most women would obtain reproductive health preventive screening if oral contraceptives were available OTC, and also highlight the need to improve access to preventive screening for all low-income women.

Deep vein thrombosis and the oestrogen content in oral contraceptives. An epidemiological analysis.

Science.gov (United States)

Kierkegaard, A

Epidemiological studies have pointed to a correlation between the oestrogen content of oral contraceptives and the risk of deep vein thrombosis (DVT). The correlation has been strongest in studies which partially consisted of adverse drug reaction reports to the Swedish Adverse Drug Reaction Advisory Committee (SADRAC). The present study analyzes the epidemiological basis of the adverse drug reaction reports on DVT in women on oral contraceptives to SADRAC. It verifies the reported correlation between the oestrogen content of the pills and the risk of DVT but it also demonstrates that this correlation probably was secondary to differences in the diagnostic standard of DVT, to differences in reporting policies to SADRAC and to an age difference between women on low-oestrogen-pills and those on high-oestrogen pills and is thus due to bias. It is concluded that adverse drug reaction reporting on oral contraceptives has been very unreliable, for which reason it cannot support any epidemiological conclusion concerning the relative thrombogenicity of high-oestrogen pills compared with that of low-oestrogen pills.

Idiopathic cerebral sinus thrombosis (CST) can cause death and serious neurological disability. It is unknown whether smoking, a major risk factor for arterial stroke, is a risk factor also for CST. This work explored the association between smoking and CST in a hospital-based, multicentric, case-control study. In order to avoid the confounding effect of the different risk factors for CST, we analysed the homogeneous subgroup of oral contraceptive users. We compared the prevalence of smoking in a group of 43 young women with CST (cases), whose oral contraceptive use was the only known risk factor, with a sample of 255 healthy contraceptive users of similar age (controls). The prevalence of smoking in cases and controls was similar (26% vs. 29%). The age and geographic area-adjusted odds ratio was 0.9; 95% confidence interval, 0.4-1.8; p=0.7. Smoking in oral contraceptive users does not appear to be associated with CST.

Full Text Available Giuseppe Benagiano, Sabina Carrara, Valentina FilippiDepartment of Gynaecology and Obstetrics, Sapienza University, Rome, ItalyAbstract: The progestational steroid norgestrel was synthesized and tested between 1960 and 1965 through an international cooperation between Wyeth, USA and Schering, Berlin. It is a mixture of two “enantiomers,” with only one form (designated as levonorgestrel biologically active. When taken orally, it is rapidly absorbed, not subjected to a “first-pass” effect and is approximately 90% bioavailable, with a circulating half-life around 15 hours. Its contraceptive action is exerted at the central (hypothalamic and peripheral (cervical mucus and endometrium levels. Levonorgestrel (LNG, alone or in combination with ethinyl estradiol (EE, is the most widely employed contraceptive progestin: it is used in combined oral contraceptives, progestogen-only pills, long-acting contraceptive implants, intrauterine contraceptive systems and in emergency contraception. It is also the steroid of choice for new oral contraceptive regimens aimed at reducing the frequency of bleeding episodes. This novel approach, already tried more than 30 years ago, gained interest around the year 2000 when surveys of women’s attitudes toward monthly menstrual bleeding started to show a major change: more and more women declared that they would welcome a hormonal contraceptive method that reduced bleeding episodes to 4, 2 or even 1 per year. At this point, while the debate on the significance and “usefulness” of menstruation went on, attention focused on new regimens. The first new modality consisted of changing the 7-day medication-free interval, either shortening it to fewer than 7 days, or by the administration of low-dose estrogens during the interval between packages. Then, continuous administration regimens started to be investigated. This, however, did not happen suddenly, since, in specific situations, doctors had for years

Safety, efficacy, actions, and patient acceptability of drospirenone/ethinyl estradiol contraceptive pills in the treatment of premenstrual dysphoric disorder

Full Text Available Lesley L Breech, Paula K BravermanDivision of Adolescent Medicine, Department of Pediatrics, Cincinnati Children’s Hospital Medical Center, University of Cincinnati College of Medicine, Cincinnati, OH, USAAbstract: Premenstrual dysphoric disorder (PMDD is estimated to affect 3%–8% of reproductive age women. Multiple therapeutic modalities have been evaluated with varying efficacy for the associated somatic and mood symptoms. The majority of older studies had shown that oral contraceptive pills (OCs were most effective for the physical symptoms. However, newer OCs containing a novel progestin, drospirenone, have shown promise in alleviating both the somatic and affective/behavioral symptoms. This progestin, which is a derivative of spironolactone, has both antimineralocorticoid and antiandrogenic activity. A 24/4 formulation containing 20 µg of ethinyl estradiol has been found effective in randomized double-blind placebo-controlled trials utilizing established scales documenting symptoms associated with PMDD. Multiple studies have shown that drospirenone-containing OCs are safe without evidence of clinically adverse effects on carbohydrate metabolism, lipids, blood pressure, weight, serum potassium or increased thrombotic events compared to other low dose OCs. In addition, significant improvements have been demonstrated in acne, hirsutism, and fluid retention symptoms. Several open label studies demonstrated good patient compliance and reported satisfaction with the method. Because of the significant placebo effect demonstrated in the blinded placebo-controlled trials, additional large randomized placebo-controlled trials are needed to confirm the efficacy of the drospirenone OCs in the treatment of PMDD. However, this OC formulation appears to be a promising therapeutic modality.Keywords: drospirenone, premenstrual dysphoric disorder, premenstrual syndrome, oral contraceptive pill

[The difficulties of contraception: conflicts and paradoxes].

Science.gov (United States)

Cribier, F

1988-06-01

This work uses clinical examples to explore sources of conflict and denial of patients and physicians during contraception consultations. The discovery of oral contraceptives (OCs) and improvements in mechanical contraception raised hopes that couples could achieve total control of their fertility. But continued high abortion rates and the persistence of sexual problems and maladjustments have demonstrated that contraception alone is not a panacea. Conflicts about contraception may be conscious and quickly expressed during a consultation, even if a medical pretext is given. The resentment when 1 partner desires a child and the other does not for example can translate into a conflict about contraception. Some women are fully aware of their own ambivalence about pregnancy and contraception and able to express it openly, but very often the woman's concerns are expressed by questions, fears, and verbal slips. The fear that pills are unnatural or will cause congenital defects can be interpreted as an expression of guilt over the pleasure that pills permit. Sterility is the ultimate fear caused by this unlimited possibility for pleasure. In the majority of cases, physical complaints are the means by which contraception clients address their physicians. In some cases, intolerance to OCs may actually be a hysterical manifestation that is not understood. Such symptoms as nausea, breast swelling, dizziness, vomiting, nervousness, and insomnia may be signs of early pregnancy as well as of intolerance for pills. Intolerance to pills may be caused by intolerance of a sexuality in which all things seem possible but in which the individual feels unrecognized by the partner. The resulting aggression may be turned inward in the form of a morbid symptom or of forgetting or stopping pill use, recourse to abortion, and demand for recognition. Acting out, especially by adolescents, is common in the area of contraception. In some cases the psychological or emotional needs of the patient

Full Text Available Oral contraceptives are known to influence the risk of cancers of the female reproductive system. Evidence regarding the relationship between injectable contraceptives and these cancers is limited, especially in black South Africans, among whom injectable contraceptives are used more commonly than oral contraceptives.We analysed data from a South African hospital-based case-control study of black females aged 18-79 y, comparing self-reported contraceptive use in patients with breast (n = 1,664, cervical (n = 2,182, ovarian (n = 182, and endometrial (n = 182 cancer, with self-reported contraceptive use in 1,492 control patients diagnosed with cancers with no known relationship to hormonal contraceptive use. We adjusted for potential confounding factors, including age, calendar year of diagnosis, education, smoking, alcohol, parity/age at first birth, and number of sexual partners. Among controls, 26% had used injectable and 20% had used oral contraceptives. For current and more recent users versus never users of oral or injectable contraceptives, the odds ratios (ORs for breast cancer were significantly increased in users of oral and/or injectable contraceptives (OR 1.66, 95% CI 1.28-2.16, p<0.001 and separately among those exclusively using oral (1.57, 1.03-2.40, p = 0.04 and exclusively using injectable (OR 1.83, 1.31-2.55, p<0.001 contraceptives; corresponding ORs for cervical cancer were 1.38 (1.08-1.77, p = 0.01, 1.01 (0.66-1.56, p = 0.96, and 1.58 (1.16-2.15, p = 0.004. There was no significant increase in breast or cervical cancer risk among women ceasing hormonal contraceptive use ≥10 y previously (p = 0.3 and p = 0.9, respectively.

Studies that rely on self-report to investigate the relationship between hormonal contraceptive use and HIV acquisition and transmission, as well as other health outcomes, could have compromised results due to misreporting. We determined the frequency of misreported hormonal contraceptive use among African women with and at risk for HIV. We tested 1102 archived serum samples from 664 African women who had participated in prospective HIV prevention studies. Using a novel high-performance liquid chromatography-mass spectrometry assay, we quantified exogenous hormones for injectables (medroxyprogesterone acetate or norethisterone), oral contraceptives (OC) (levonorgestrel or ethinyl estradiol) and implants (levonorgestrel or etonogestrel) and compared them to self-reported use. Among women reporting hormonal contraceptive use, 258/358 (72%) of samples were fully concordant with self-report, as were 642/744 (86%) of samples from women reporting no hormonal contraceptive use. However, 42/253 (17%) of samples from women reporting injectable use, 41/66 (62%) of samples from self-reported OC users and 3/39 (8%) of samples from self-reported implant users had no quantifiable hormones. Among self-reported nonusers, 102/744 (14%) had ≥1 hormone present. Concordance between self-reported method and exogenous hormones did not differ by HIV status. Among African women with and at risk for HIV, testing of exogenous hormones revealed agreement with self-reported contraceptive use for most women. However, unexpected exogenous hormones were identified among self-reported hormonal contraceptive users and nonusers, and an important fraction of women reporting hormonal contraceptive use had no hormones detected; absence of oral contraceptive hormones could be due, at least in part, to samples taken during the hormone-free interval. Misreporting of hormonal contraceptive use could lead to biased results in observational studies of the relationship between contraceptive use and health

In a separate experiment, aromatase and cyclo-oxygenase-2 expression were investigated in the endometrial tissue of 42 patients submitted to laparoscopy and hysteroscopy for the management of endometriosis. Sixteen of these patients were using oral contraceptives alone prior to hospital admission, while the remaining 26 were using them in combination with resveratrol. Inhibition of both aromatase and cyclo-oxygenase-2 expression was significantly greater in the eutopic endometrium of patients using combined drospirenone + resveratrol therapy compared with the endometrium of patients using oral contraceptives alone.Conclusion: These results suggest that resveratrol potentiates the effect of oral contraceptives in the management of endometriosis-associated dysmenorrhea by further decreasing aromatase and cyclo-oxygenase-2 expression in the endometrium.Keywords: resveratrol, drospirenone, endometriosis, dysmenorrhea, cyclo-oxygenase-2

Little is known about how parental gender equality early in their children lives can influence daughters' decision to use contraceptive pills. The study aimed at exploring whether maternal working time and paternity leave in Sweden during the first two years of their daughters' lives is associated with the use of oral contraceptives when they are adolescents or young adults. The study population was selected from a cohort of all Swedish fathers and mothers who had their first child together between 1988 and 1989 (n = 57,520 family units). Multivariate logistic regression was used to estimate the association. Mothers' longer working time was mildly associated with daughters' oral contraceptive pill use, though no clear trend was observed. Longer paternity leave periods (>30 days) were not associated with use of oral contraceptives among their daughters, but 1-30 day periods showed a mild positive association. For maternal working time, there seems to be an association, but trends by working hours are not clear. There is no clear association between paternity leave during the first two years of their daughters' life and the use of oral contraceptives when they are adolescents and young adults.

The effect of oral contraceptives on 131 I uptake, the depuration rate of this isotope and the PBI was studied in 24 euthyroid female patients. The dose administered was of 2.5 mg of norestinodrel and 0.05 mg of ethynil estradiol. The data were submitted to a statistical study applying analysis of variance, comparison of the means, determination of the standard deviations and the confidence interval. It is concluded that drug does affect thyroid function and that these effects may cause certain disturbances, as arterial hypertension, thrombosis, etc., in patients under prolonged contraceptive treatment [pt

The Emotional Responses of Married Women Receiving Oral Contraceptives

1965-01-01

One hundred women taking oral contraceptives were questioned concerning their opinions about personal and sociological effects of this method of conception control. Fifty-three per cent reported improved coital satisfaction while 4% noted the opposite effect. Libido was increased in 22% and decreased in 13%. One woman in five believed that an increase in premarital and extramarital sexual activity would take place in the general population as a result of tablet-induced infertility. The problem of population control is discussed. It is paradoxical that the incidence of unplanned pregnancies continues to increase despite the availability of completely reliable conception control. This reflects present inability to communicate contraceptive knowledge to the appropriate people. PMID:14292887

, the vast majority chose oral contraceptives (OCs). In 1975, 91% of clients obtaining contraception left with some form of OC compared to 85% at the end of the period. The decrease was more marked for older clients. The decrease in the popularity of the combined pill was offset somewhat by the increased use of the progestogen only pill. Despite the shifts, the vast majority of clients continued to use some form of OC. In 1980 a quarter of sexually experienced new clients reported no form of contraception more effective than withdrawal. In 1980 over 1/3 of the sexually experienced teenage clients reported no contraception other than withdrawal. The 2 most popular methods were condoms and OC, together accounting for about 90% of contraception use.

We aimed to determine the impact of an oral contraceptive (OC) treatment on health-related quality of life (HRQOL), depressive and anxiety symptoms in polycystic ovary syndrome (PCOS). OC therapy in PCOS improves hirsutism and menstrual disturbances, along with HRQOL. This improvement is not associated with any change in the prevalence of depressive and anxiety symptoms. WHAT IS KNOWN AND WHAT THIS ARTICLE ADDS: Limited data are available regarding the effects of an OC on HRQOL, and depressive and anxiety symptoms in PCOS. This study reports the effects of the ethinyl estradiol/drospirenone (EE/DRSP) OC on an HRQOL questionnaire for women with PCOS (PCOSQ), depressive and anxiety symptoms after 6 months of treatment. Prospective observational study. All participants completed PCOSQ, Beck Depression Inventory, Hospital Anxiety and Depression Scale and General Health Questionnaire. Serum androgens, fasting insulin, fasting and postload glucose values during an oral glucose tolerance test were measured. Changes in these variables and the scores of questionnaires were evaluated after 6 months of treatment with EE/DRSP (3 mg/30 μg). Thirty-six patients with PCOS without a previous psychiatric diagnosis were included in the study. The main complaints of the patients were hirsutism and irregular menses. Accordingly, menstrual and hirsutism problems were the most serious concerns followed by emotional problems on the PCOSQ. Eight patients (22.2%) had clinical depression scores. After treatment, regular menstrual cycles were attained and hirsutism was significantly improved in all patients. Hirsutism and emotion domains of the PCOSQ improved at 6 months (P< 0.05 for both). Depression was improved in five of eight depressive patients and four new patients showed increased depression scores. Overall, depression, anxiety mean scores and depression rates did not show a significant change. The study is subject to the strengths and limitations of observational study design. A

Recent studies showed differences in the risk of venous thrombosis between different combined hormonal contraceptives. Database studies comprising large cohorts can add relevant aspects from daily clinical practice. The purpose of this study was to evaluate different progestogen in combination with ethinylestradiol on the risk of venous thrombosis in Germany. Computerized data from 68,168 contraceptive users in gynecological practices throughout Germany (Disease Analyzer Database) were analyzed. The adjusted odds ratios for risk of thrombosis were estimated in users of different oral contraceptive (OC) formulations relative to users of levonorgestrel-containing preparations. In total, 38 (0.06 %) of the 68,168 contraceptive users had a recorded diagnosis of thrombosis within 365 days after the initial prescription. The adjusted risk was 1.95 for desogestrel (95 % CI 0.52-7.29), 2.97 for dienogest (95 % CI 0.96-9.24), 1.57 for drospirenone (95 % CI 0.46-5.38), 2.54 for chlormadinone (95 % CI 0.72-9.04), and 3.24 for norgestimate (95 % CI 0.59-17.75) compared to levonorgestrel. None of those findings reached statistical significance. The maximum absolute increase versus levonorgestrel was 6 cases per 10,000 women (n.s.). The study shows the low incidence rates of thrombosis in OC users. Since there is no significant difference, this study does not confirm an increased risk but shows only a tendency for this risk of third- and fourth-generation OC versus levonorgestrel-containing products.

Objective: To explore the effect of short-acting combined oral contraceptives on vaginal bleeding after induced abortion. Methods: A total of 726 patients, who had took induced abortion from July 2016 to September 2016 in obstetrics and gynecology outpatient department of Nanfang Hospital, Southern Medical University, were included and divided into the observation group and the control group according to whether they took short-acting combined oral contraceptives after induced abortion, with 312 cases, 414 cases respectively.The vaginal bleeding days, amounts of bleeding, the endometrial thickness 3 weeks later, and whether the patient had menstrual recovery on time were observed and analyzed. Results: The observation group had less bleeding days and amount of bleeding, compared with the control group.69.87% (218/312) patients of the observation group had more than 8mm of endometrial thickness on postoperative day 21, while 61.11% (253/414) of the observation group did, the difference was statistically significant ( P =0.034).90.06% (281/312) patients of the observation group had menstrual recovery on time, while 82.61% (342/414) of the observation group did, the difference was statistically significant ( P =0.004). Conclusion: Short-acting combined oral contraceptives after induced abortion can significantly shorten the vaginal bleeding days, reduce the amount of bleeding, promote endometrial repair and menstrual recovery.There fore, it has important clinical significance and application value.

This study investigated sociological factors that may influence women's utilization of and adherence to oral contraceptive pills. This was a retrospective cross-sectional study using the 2010-2012 Medical Expenditure Panel Survey. Female adults aged 18-50 years were included. Logistic regression was performed to discern women's decisions to use oral contraceptive pills or not. Ordinary least squares and Poisson regressions were conducted to examine the number of oral contraceptive pills received, refill frequency, and annual out-of-pocket expenditure on oral contraceptive pills. Covariates were based on the Andersen model of health care utilization. Among the study sample (weighted n = 207,007,531), 14.8% were oral contraceptive pill users. Factors positively related to oral contraceptive pill use included non-Hispanic white ethnicity, younger age, not currently married, having private insurance, residing in the Midwest, higher education level, and higher annual family income. Being non-Hispanic white and having a higher education level were positively related to oral contraceptive pill adherence. Our findings therefore demonstrate disparities in oral contraceptive pill utilization and adherence, especially according to women's race/ethnicity and educational level. This study serves as a baseline assessment for the impact of the Affordable Care Act on oral contraceptive pill utilization and adherence for future studies. © The Author(s) 2015.

2008-08-01

The present study investigated American women's attitudes toward menstrual suppression and the effect of priming attitudes toward menstruation on women's willingness to suppress menstruation. One hundred college women randomly were assigned to either a positive priming group or a negative priming group. The positive priming group first completed the menstrual joy questionnaire (MJQ) followed by a willingness to suppress menstruation (WSM) questionnaire, the beliefs and attitudes toward menstruation (BATM) questionnaire, the menstrual distress questionnaire (MDQ), and a demographic questionnaire. The negative priming group completed, in the following order: the MDQ, WSM, BATM, MJQ, and demographics. Priming affected women's reports of positive cycle-related changes on the MDQ, but not women's willingness to suppress menstruation. Higher scores on the MJQ, positive attitudes toward menstrual suppression, and previous oral contraceptive (OC) use were predictors of women's willingness to suppress menstruation. Women's primary source of information about menstrual suppression was "media," and their primary concern was "safety." Thus, researchers should continue to investigate the long-term effects of continuous OC use and to analyze information about menstrual suppression in the popular press.

A cross-sectional study of different patterns of oral contraceptive use among premenopausal women and circulating IGF-1: implications for disease risk

Full Text Available Abstract Background Insulin-like growth factor-1 (IGF-1 is important in normal growth, development, and homeostasis. Current use of oral contraceptives (OC decreases IGF-1 concentrations; however, the effect of past use, age/timing of use, and type of OC used on IGF-1 levels is unknown. OC are the most commonly used form of birth control worldwide. Both IGF-1 and OC use have been linked to premenopausal breast and colorectal cancers, osteoporosis and cardiovascular disease (CVD. Understanding the effects of different patterns of OC use on IGF-1 levels may offer insight into its influence on disease risk in young women. Methods In a cross-sectional study of 328 premenopausal women ages 18 to 21 and 31 to 40 we examined the relationship between different patterns of OC use and circulating IGF-1 using adjusted linear regression analysis. Information on OC use was obtained through an interviewer administered questionnaire. Plasma IGF-1 was assessed with enzyme linked immunosorbent assay (ELISA. Results Among women aged 18 to 21, ever OC use was significantly associated with decreased IGF-1 levels compared to never use (β = -57.2 ng/ml, 95% confidence interval (CI: -88.7, -25.8. Among women aged 31 to 40, past users who first used OC at 25 years of age or older (β = 43.8 ng/ml, 95% CI: 8.8, 78.8, in the last 15 years (β = 35.1 ng/ml, 95% CI: 9.3, 61.0 or after 1995 (β = 46.6 ng/ml, 95% CI: 13.4, 79.8 had significantly higher IGF-1 levels compared to never users. Conclusion This is the first study to highlight the long term effects of OC use after cessation on IGF-1 levels among premenopausal women, which previously were thought to be transitory. Future studies of past use and IGF-1 levels are required and must consider age/timing of use and type/generation of OC used. Additional studies are needed to confirm the potential mediation of IGF-1 levels in the links between OC use and health outcomes.

To assess the effect of oral and injectable contraceptive use compared to nonhormonal contraceptive use on HIV acquisition among Southern African women enrolled in a microbicide trial. This is a prospective cohort study using data from women enrolled in HIV Prevention Trials Network protocol 035. At each quarterly visit, participants were interviewed about self-reported contraceptive use and sexual behaviors and underwent HIV testing. Cox proportional hazards regression was used to assess the effect of injectable and oral hormonal contraceptive use on HIV acquisition. The analysis included 2830 participants, of whom 106 became HIV infected (4.07 per 100 person-years). At baseline, 1546 (51%) participants reported using injectable contraceptives and 595 (21%) reported using oral contraceptives. HIV incidence among injectable, oral and nonhormonal contraceptive method users was 4.72, 2.68 and 3.83 per 100 person-years, respectively. Injectable contraceptive use was associated with a nonstatistically significant increased risk of HIV acquisition [adjusted hazard ratio (aHR)=1.17; 95% confidence interval (CI) 0.70, 1.96], while oral contraceptive use was associated with a nonstatistically significant decreased risk of HIV acquisition (aHR=0.76; 95% CI 0.37,1.55). In this secondary analysis of randomized trial data, a marginal, but nonstatistically significant, increase in HIV risk among women using injectable hormonal contraceptives was observed. No increased HIV risk was observed among women using oral contraceptives. Our findings support the World Health Organization's recommendation that women at high risk for acquiring HIV, including those using progestogen-only injectable contraception, should be strongly advised to always use condoms and other HIV prevention measures. Among Southern African women participating in an HIV prevention trial, women using injectable hormonal contraceptives had a modest increased risk of HIV acquisition; however, this association was

In contrast with migraine, little is known about the relation between cluster headache and menstrual cycle, oral contraceptives, pregnancy, and menopause. A population based questionnaire study was performed among 224 female cluster headache patients, and the possible effect of hormonal influences on cluster headache attacks studied. For control data, a similar but adjusted questionnaire was sent to healthy volunteers and migraine patients. It was found that menstruation, use of oral contraceptives, pregnancy, and menopause had a much smaller influence on cluster headache attacks than in migraine. Cluster headache can, however, have a large impact on individual women, for example to refrain from having children. PMID:16407458

Objectives To assess the level of risk for women who seek emergency contraception through various clinical routes and the opportunities for improved care provision. Methods This study looked at a retrospective cohort to assess contraception and other reproductive health outcomes among women aged 15-44 who accessed oral levonorgestrel emergency contraception through an office visit or the call center at Kaiser Permanente Northern California from 2010 to 2011. Results Of 21,421 prescriptions, 14,531(67.8%) were accessed through the call center. In the subsequent 12 months, 12,127(56.6%) women had short-acting contraception (pills, patches, rings, depot medroxyprogesterone) dispensed and 2,264(10.6%) initiated very effective contraception (intrauterine contraception, implants, sterilization). Initiation of very effective contraception was similar for women who accessed it through the call center -1,569(10.8%) and office visits – 695(10.1%) (adjusted OR 1.02 95% confidence interval (CI) 0.93-1.13). In the subsequent 6 months, 2,056(9.6%) women became pregnant. Women who accessed emergency contraception through the call center were less likely to become pregnant within 3 months of accessing emergency contraception than woman who accessed it through office visits (adjusted OR 0.82 95% CI 0.72-0.94); however they were more likely to become pregnant within 4-6 months (adjusted OR 1.37 95%CI 1.16-1.60). Among women who were tested for chlamydia and gonorrhea, 689(7.8%) and 928(7.9%) were positive in the 12 months before and after accessing emergency contraception, respectively. Conclusions Protocols to routinely address unmet need for contraception at every call for emergency contraception and all office visits including visits with primary care providers should be investigated.

Crying, a complex neurobiological behavior with psychosocial and communication features, has been little studied in relationship to the menstrual cycle. In the Mood and Daily Life study (MiDL), a community sample of Canadian women aged 18-43 years, n=76, recorded crying proneness and crying frequency daily for six months along with menstrual cycle phase information. Crying proneness was most likely during the premenstruum, a little less likely during menses and least likely during the mid-cycle phase, with statistically significant differences although the magnitude of these differences were small. By contrast, actual crying did not differ between the three menstrual cycle phases. Oral contraceptive use did not alter the relationship between menstrual cycle phase and either crying variable. A wide range of menstrual cycle phase - crying proneness patterns were seen with visual inspection of the individual women's line graphs. timing of ovulation was not ascertained. Using a three phase menstrual cycle division precluded separate late follicular and early luteal data analysis. The sample size was inadequate for a robust statistical test of actual crying. reproductive aged women as a group report feeling more like crying premenstrually but may not actually cry more during this menstrual cycle phase. Individual patterns vary substantially. Oral contraceptive use did not affect these relationships. Suggestions for future research are included. Copyright © 2016 Elsevier B.V. All rights reserved.

Almost 50% of pregnancies in the United States are unwanted or mistimed. Notably, just over one-half of unintended pregnancies occurred when birth control was being used, suggesting inappropriate or poor use or contraceptive failure. About two-thirds of all women who are of reproductive age use contraceptives, and oral hormonal contraceptives remain the most common contraceptive method. Often, contraceptive products are obtained in community pharmacies. The purpose of this study was to determine whether a pharmacy-based intervention would impact sales of contraceptive products in pharmacies. This study was conducted in Iowa and used a quasi-experimental design including 55 community pharmacies (independent and grocery) in 12 counties as the intervention and 32 grocery pharmacies in 10 counties as a comparison group. The passive intervention was focused towards 18-30 year old women who visited community pharmacies and prompted those of childbearing age to "plan your pregnancy" and "consider using birth control". The intervention was delivered via educational tri-fold brochures, posters and 'shelf talkers.' Data sources for evaluation were contraceptive sales from intervention and comparison pharmacies, and a mixed negative binomial regression was used with study group*time interactions to examine the impact of the intervention on oral contraceptive and condom sales. Data from 2009 were considered baseline sales. From 2009 to 2011, condom sales decreased over time and oral contraceptives sales showed no change. Overall, the units sold were significantly higher in grocery pharmacies than in independent pharmacies for both contraceptive types. In the negative binomial regression for condoms, there was an overall significant interaction between the study group and time variables (p = 0.003), indicating an effect of the intervention, and there was a significant slowing in the drop of sales at time 3 in comparison with time 1 (p sales compared to grocery pharmacies

Background and Objective : Contraceptive pills are generally taken orally and can cause side effects such as nausea, vomiting and hypertension. The vaginal use of these pills can reduce such complications. Our objective was to compare the efficacy and side effects of low dose contraceptive pills by oral and vaginal route in the management of dysfunctional uterine bleeding-(DUB) Methods: This comparative observational study was conducted at Beheshti and Alzahra (SA) teaching hospitals, affiliated to Isfahan University of Medical Sciences in 2010-2011. One hundred women who presented with DUB were randomly assigned into two groups of equal number, receiving the low dose oral contraceptive pills by oral or vaginal route for three month. The amount and duration of bleeding were compared at the beginning and at the end of the study and side effects by these two methods compared. The results of this study showed that both oral and vaginal routes effectively reduced the duration and amount of bleeding due to DUB after three courses of treatment. This effect was better in the vaginal method compared with oral administration (P = 0.03). Regarding the side effects, nausea and vomiting were significantly higher in the oral group than in the vaginal group (P = 0.03). Vulvovaginitis infection was more frequent in the vaginal group than in the oral group (P = 0.03). Low dose contraceptive pills are effective in reducing the amount, time, and duration of bleeding in patients with DUB. In addition, reduction of gastrointestinal side effects by vaginal route helps to use these pills by the patient with proper training of physicians, midwives and patients.

In Nigeria about 50% of oral contraceptive pill users obtain their products from proprietary patent medicine vendors (PPMVs). This group of service providers are poorly trained and have very limited knowledge about contraception. This paper investigated the nature of the advice offered to simulated current and potential users of oral contraceptive pills. The main objective was to assess the nature and quality of advice provided by PPMVs to pill users. This study is based on findings from a 'mystery client' approach in which three scenarios related to contraceptive pill use were simulated. Each of the 12 mystery clients simulated one of the following three scenarios: new pill users (new to family planning or switching from condom to pills); user seeking a resupply of pills; and dissatisfied pill users intending to discontinue use. Simple random sampling was used to select 410 PPMVs from a total of 1,826 in four states in Nigeria. Qualitative study using in-depth interviews was also conducted. A majority of the PPMVs had pills in stock on the day of the survey and resupplied pills to the clients. PPMVs also understood the reason and importance of referring clients who were new adopters of oral contraceptive methods to a health facility; 30% of the PPMVs referred new adopters to a health facility. However, demand from clients who do not want to go to health care facilities (for various reasons) necessitated the provision of oral contraceptive pills to 41% of the first time users. Some PPMVs prescribed treatment to mystery clients who presented with perceived complications arising from the use of pills, while 49% were referred to a health facility. The advice given by PPMVs often falls short of safety guidelines related to the use of oral contraceptive pills. There is a need to continuously update knowledge among the PPMVs to ensure that they provide quality oral contraceptive services as PPMVs bridge the gap between medical experts and users in rural communities.

Full Text Available Abstract Purpose To determine the influence of menstrual irregularity, oral contraceptive use and other factors on bone mineral density (BMD and bone size at different skeletal sites in 135 college-aged fit women. Methods Menstrual history, oral contraceptive use, exercise history, and nutritional factors including calcium, caffeine, and alcohol intake as well as tobacco use were determined by written survey. Height, weight and fitness levels were measured. Spine and hip BMD were measured by dual x-ray absorptiometry (DXA, calcaneus BMD by peripheral DXA, and tibial bone mineral content (BMC and size by peripheral Quantitative Computed Tomography (pQCT. Results The mean age was 18.4 ± 0.8 years. Weight and prior exercise were positively related to BMD at most skeletal sites and to tibial bone size. Milk intake was positively related to calcaneal BMD, tibial BMC and cortical thickness. Fracture history was an important predictor of spine, hip and heel BMD. Women who had ≥ 10 menstrual cycles in the year prior to BMD measurement had higher BMD at all sites as well as a greater tibial mineral content and cortical thickness than women who had oligomenorrhea/amenorrhea (≤ 9 cycles in the prior year; all p p p = 0.04, smaller tibial periosteal circumference and lower tibial mineral content (p Conclusion In a population of fit, college-aged women, OC use and oligomenorrhea were associated with reduced BMD and bone size. Weight, as well as prior exercise and milk intake was positively related to bone density and size at some skeletal sites. Understanding these relationships would help improve skeletal health in young women.

Full Text Available Hormonal action is one of the main factors for behavioral change observed in women, during the menstrual cycle, and especially in the premenstrual period, most women report a variation of mood and anxiety. The aim of this work was to verify the degrees of anxiety during the menstrual cycle, charting their variation and the possible influence of oral contraceptive use. For this purpose 32 women, divided in two groups according to the use (B or not use (A of oral contraceptive, with selfapplication of the STAI (State-Trait Anxiety Inventory at three different times: before, during and after menstruation. The data was tabulated and analyzed statistically, indicating a variation of anxiety level for different menstrual periods, but with no significance as to anxiety type (trait or state or to the ingestion of contraceptive. For Trait-Anxiety, the post-test (Boferroni T-Test of variation among periods indicated significant difference for post-menstrual and other periods, in the A group; and between the premenstrual and menstrual periods, in the B group. For State Anxiety, the data indicated significant differences between the premenstrual and menstrual periods, in the A group, and between the premenstrual and menstrual periods and the menstrual and post-menstrual in the B group. The results indicate that: 1 the menstrual cycle is a generator of variations of related anxiety; 2 the use of oral contraceptives does not alter this relation; and 3 the correlated diminution of the Trait Anxiety may indicate alteration in self-perception of women during the menstrual cycle.

Contraception.

Contraception is discussed in this article. Abstinence is the only certain method of contraception. The normal pregnancy rate in the normal unprotected population would be somewhere between 60 to 80 pregnancies per 100 woman-years. Contraceptive methods vary in effectiveness. The failure rate of the safe period method is between 10-50 per 100 woman-years while the failure rate of spermicidal pessaries and creams is somewhere between 20 and 80 per 100 woman-years. Occlusive diaphragms fit over the anterior vaginal wall, such as the Dutch cap, or over the cervix itself, such as the cervical or Dumas cap. The failure rate of the Dumas cap is about 4 per 100 woman-years and the Dutch cap 6 per 100 woman-years. Perhaps the ideal female contraceptive is just around the corner in the alteration of cervical mucus by changing its pH or other constituents so that it becomes a spermicidal barrier or causes either sperm agglutination or a reduction of sperm motility. Between 8% and 15% of plastic IUDs are extruded spontaneously and a further 10% may be removed because of pain, intermenstrual bleeding, or menorrhagia. They are well tolerated in about 80% of patients, in whom the failure rate is about 2 per 100 woman years. The douche and sponge are unacceptable and unreliable methods of contraception. The main advance in contraceptive technique over the past 10 years has been the introduction of the oral contraceptives. The combined type of pill was developed first, followed by the sequential type. It has been estimated that between half a million and 1 million women in this country now take oral contraceptive pills and nothing detrimental has so far been proved about the method in spite of persistent and widely published doubts about its possible dangers. The failure rate of the oral contraceptives is less than 1 per 100 woman years.

both users and non-users of contraception. No trials were at low risk of bias in all areas assessed.One trial in the USA reported improved self reported oral contraceptive (OC) continuation at six months from an intervention comprising a range of uni-directional and interactive text messages (RR 1.19, 95% CI 1.05 to 1.35). One trial in Cambodia reported increased self reported use of effective contraception at four months post abortion from an intervention comprising automated interactive voice messages and phone counsellor support (RR 1.39, 95% CI 1.17 to 1.66).One feasibility trial in the USA reported a lower mean number of days between scheduled and completed attendance for the first but not subsequent Depo-Provera appointments using clinic records from an intervention comprising reminders and healthy self management text messages (mean difference (MD) -8.60 days, 95% CI -16.74 to -0.46). Simple text message OC reminders had no effect on missed pills as assessed by electronic medication monitoring in a small trial in the USA (MD 0.5 missed pills, 95% CI -1.08 to 2.08). No effect on self reported contraception use was noted amongst isotretinoin users from an intervention that provided health information via two uni-directional text messages and mail (RR 1.26, 95% CI 0.84 to 1.89). One trial assessed potential adverse effects of the intervention and reported no evidence of road traffic accidents or domestic abuse. Our review provides limited evidence that interventions delivered by mobile phone can improve contraception use. Whilst evidence suggests that a series of interactive voice messages and counsellor support can improve post-abortion contraception, and that a mixture of uni-directional and interactive daily educational text messages can improve OC adherence, the cost-effectiveness and long-term effects of these interventions remain unknown. Further high-quality trials are required to robustly establish the effects of interventions delivered by mobile phone to

Idiopathic cerebral-vein thrombosis can cause serious neurologic disability. We evaluated risk factors for this disorder, including genetic risk factors (mutations in the genes encoding factor V and prothrombin) and nongenetic risk factors (such as the use of oral contraceptive agents). We compared the prevalence of these risk factors in 40 patients with cerebral-vein thrombosis, 80 patients with deep-vein thrombosis of the lower extremities, and 120 healthy controls. The G1691A mutation in the factor V gene and the G20210A prothrombin-gene mutation, which are established genetic risk factors for venous thrombosis, were studied. We also assessed the use of oral contraceptives and other risk factors for thrombosis. The prevalence of the prothrombin-gene mutation was higher in patients with cerebral-vein thrombosis (20 percent) than in healthy controls (3 percent; odds ratio, 10.2; 95 percent confidence interval, 2.3 to 31.0) and was similar to that in patients with deep-vein thrombosis (18 percent). Similar results were obtained for the mutation in the factor V gene. The use of oral contraceptives was more frequent among women with cerebral-vein thrombosis (96 percent) than among controls (32 percent; odds ratio, 22.1; 95 percent confidence interval, 5.9 to 84.2) and among those with deep-vein thrombosis (61 percent; odds ratio, 4.4; 95 percent confidence interval, 1.1 to 17.8). For women who were taking oral contraceptives and who also had the prothrombin-gene mutation (seven patients with cerebral-vein thrombosis but only one control), the odds ratio for cerebral-vein thrombosis rose to 149.3 (95 percent confidence interval, 31.0 to 711.0). Mutations in the prothrombin gene and the factor V gene are associated with cerebral-vein thrombosis. The use of oral contraceptives is also strongly and independently associated with the disorder. The presence of both the prothrombin-gene mutation and oral-contraceptive use raises the risk of cerebral-vein thrombosis further.

Practice Bulletin No. 152: Emergency Contraception.

Science.gov (United States)

2015-09-01

Emergency contraception, also known as postcoital contraception, is therapy used to prevent pregnancy after an unprotected or inadequately protected act of sexual intercourse. Common indications for emergency contraception include contraceptive failure (eg, condom breakage or missed doses of oral contraceptives) and failure to use any form of contraception (). Although oral emergency contraception was first described in the medical literature in the 1960s, the U.S. Food and Drug Administration (FDA) approved the first dedicated product for emergency contraception in 1998. Since then, several new products have been introduced. Methods of emergency contraception include oral administration of combined estrogen-progestin, progestin only, or selective progesterone receptor modulators and insertion of a copper intrauterine device (IUD). Many women are unaware of the existence of emergency contraception, misunderstand its use and safety, or do not use it when a need arises (). The purpose of this Practice Bulletin is to review the evidence for the efficacy and safety of available methods of emergency contraception and to increase awareness of these methods among obstetrician-gynecologists and other gynecologic providers.

Instructions on what to do after pills are missed are critical to reducing unintended pregnancies resulting from patient non-adherence to oral contraceptive (OC) regimens. Missed pill instructions have previously been criticized for being too complex, lacking a definition of what is meant by "missed pills," and for being confusing to women who may not know the estrogen content of their formulation. To help inform the development of missed pill guidance to be included in the forthcoming US Selected Practice Recommendations, the objective of this systematic review was to evaluate the evidence on patient understanding of missed pill instructions. We searched the PubMed database for peer-reviewed articles that examined patient understanding of OC pill instructions that were published in any language from inception of the database through March 2012. We included studies that examined women's knowledge and understanding of missed pill instructions after exposure to some written material (e.g., patient package insert, brochure), as well as studies that compared different types of missed pill instructions on women's comprehension. We used standard abstract forms and grading systems to summarize and assess the quality of the evidence. From 1620 articles, nine studies met our inclusion criteria. Evidence from one randomized controlled trial (RCT) and two descriptive studies found that more women knew what to do after missing 1 pill than after missing 2 or 3 pills (Level I, good, to Level II-3, poor), and two descriptive studies found that more women knew what to do after missing 2 pills than after missing 3 pills (Level II-3, fair). Data from two descriptive studies documented the difficulty women have understanding missed pill instructions contained in patient package inserts (Level II-3, poor), and evidence from two RCTs found that providing written brochures with information on missed pill instructions in addition to contraceptive counseling significantly improved

To study the effects of laparoscopic ovarian cauterization and combination of long-acting GnRH agonist (GnRH-a) and oral contraceptive (OC) therapy on endocrine changes in women with clomiphene citrate (CC)- resistant polycystic ovary disease (PCOD). Prospective, randomized. University-based infertility clinic. Seventeen women with CC-resistant PCOD were included randomly in the study to either laparoscopic ovarian cautery or GnRH-a and OC therapy for 3 months. Serum concentrations of LH, FSH, androstenedione (A), T, and sex hormone-binding globulin (SHBG) were determined before each therapeutic approach and during the follicular phase of first menstrual cycle after the cessation of each treatment. The mean serum concentrations and the clinical profiles were similar in both groups. Both groups showed significant changes in LH, FSH, A, T, and SHBG compared with pretreatment levels. There were no significant differences in the final concentrations of LH, FSH, and A between the two study groups after each treatment, whereas T and SHBG levels were significantly different in the goserelin and OC group. The decrease in LH and increase in SHBG serum concentrations were greater in the goserelin and OC-treated women [-59% and + 5.9% versus - 70% and + 13.5%, respectively]. Although the SHBG concentration increased in both groups, the serum SHBG concentration of the goserelin and OC group was significantly higher than the other group. Both therapeutic modalities revealed similar effects on the endocrine profiles in women with CC-resistant PCOD. Considering the invasiveness, cost, and potential complications of laparoscopic ovarian cauterization, noninvasive medical treatment with GnRH-a and OC combination may be more effective in restoring the optimal follicular environment in women with PCOD.

Acne vulgaris may be effectively treated with combination oral contraceptive pills (COCs) in women. COCs may be useful in any woman with acne in the absence of known contraindications. When prescribing a COC to a woman who also desires contraception, the risks of the COC are compared with the risks associated with pregnancy. When prescribing a COC to a woman who does not desire contraception, the risks of the COC must be weighed against the risks associated with acne. COCs may take 3 cycles of use to show an effect in acne lesion count reductions. Copyright © 2016 Elsevier Inc. All rights reserved.

Defined here as a method requiring attention no more often than every 3 years, forgettable contraception includes sterilization (female or male), intrauterine devices, and implants. Five principal factors determine contraceptive effectiveness: efficacy, compliance, continuation, fecundity, and the timing of coitus. Of these, compliance and continuation dominate; the key determinants of contraceptive effectiveness are human, not pharmacological. Human nature undermines methods with high theoretical efficacy, such as oral contraceptives and injectable contraceptives. By obviating the need to think about contraception for long intervals, forgettable contraception can help overcome our human fallibility. As a result, all forgettable contraception methods provide first-tier effectiveness (contraceptives today with exclusively first-tier effectiveness is the one that can be started -- and then forgotten for years.

Post-coital contraception.

137,000 British women chose to have an abortion in 1981 and about 25% were teenagers. A recent estimate noted that 10% of unintended pregnancies could have been avoided if postcoital contraception had been obtainable. The availability of postcoital contraception is limited and few doctors have much knowledge of or interest in this contraceptive method. 2 questions that arise are why have doctors been so slow to adopt this effective method of birth control and what are the chances of its availability in the National Health Service (NHS) improving. Postcoital contraception is a comparatively new and until recently unpublicized fertility control method, and there was little knowledge of it among the general population or the medical profession. Doctors' ignorance and reluctance to provide the method may have been due in part to the fact that the pharmaceutical firms have been hesitant to recommend oral contraceptive (OC) pills for this use. There is no specially packaged product, and it is necessary for a patient to be given 4 pills from a 21-pill pack. This has meant that the method has not been advertized, as most new methods would be, in the medical magazines. Hopefully, this lack of knowledge has been rectified by the Family Planning Association. As part of its campaign to launch the method, it has sent details to all general practitioners. Attitudes to postcoital contraception are important, and clearly there are strong parallels with the abortion issues and legal and moral undercurrents as well. Many doctors might have been put off providing postcoital contraception by the experience of the 2 clinics (BPAS in Sheffield and the Caithorpe Nursing Home in Birmingham) which had been reported by Life, an antiabortion pressure group, to the Director of Public Prosecutions under the Offences Against the Persons Act 1863. But on May 10, 1983 the Attorney General announced that the provisionof postcoital contraception is not a criminal offense. This statement may not be

Objective To analyze the factors influencing behavior of women in choosing contraceptive methods. Material and Methods A total of 4022 women who were admitted to our clinic in a year, were the subjects in this current study for contraception choices. Relationship between the current contraceptive choice and the age, marital status, educational level, gravidity and induced abortions were evaluated. Results Current users of any contraceptive methods were found to make up thirty-three percent of the entire study population. The most preferred method of contraception was an intrauterine device (46.4%), followed by, condom (19.2%), coitus interruptus (16.4%), tubal sterilization (11%), oral contraceptives (5.7%) and lastly the “other methods” that consisted of depot injectables and implants (1.2%). Among other contraceptive methods, the condom was found to be used mostly by the younger age group (OR:0.956, 95% CI:0.936–0.976, p<0.001), while tubal sterilization was preferred mainly by the elderly population (p<0.001, OR:1.091, 95% CI:1.062–1.122). Women that have a higher educational level, were found to use OC (76.3%, OR:5.970, 95% CI:3.233–11.022), tubal sterilization (59.6%, OR:4.110, 95% CI:2.694–6.271) and other methods (62.5%, OR:3.279, 95% CI:1.033–10.402) more commonly than the low educational group (p<0.001). Conclusion These results demonstrated that the rates of both contraception utilization and the usage of more effective methods of contraception need to be increased by providing better family planning systems and counselling opportunities.

Ongoing intrinsic brain activity in resting, but awake humans is dominated by alpha oscillations. In human, individual alpha frequency (IAF) is associated with cognitive performance. Noticeable, performance in cognitive and emotional tasks in women is associated with menstrual cycle phase and sex hormone levels, respectively. In the present study, we correlated frequency of alpha oscillation in resting women with menstrual cycle phase, sex hormone level, or use of oral contraceptives. Electroencephalogram (EEG) was recorded from 57 women (aged 24.07 ± 3.67 years) having a natural menstrual cycle as well as from 57 women (aged 22.37 ± 2.20 years) using oral contraceptives while they sat in an armchair with eyes closed. Alpha frequency was related to the menstrual cycle phase. Luteal women showed highest and late follicular women showed lowest IAF or center frequency. Furthermore, IAF as well as center frequency correlated negatively with endogenous estradiol level, but did not reveal an association with endogenous progesterone. Women using oral contraceptives showed an alpha frequency similar to women in the early follicular phase. We suggest that endogenous estradiol modulate resting alpha frequency.

An association between serum levels of perfluoroalkyl substances (PFAS) and endometriosis has recently been reported in an epidemiologic study. Oral contraceptive use to treat dysmenorrhea (pelvic pain associated with endometriosis) could potentially influence this association by reducing menstrual fluid loss, a route of excretion for PFAS. In this study, we aimed to evaluate the influence of differential oral contraceptive use on the association between PFAS and endometriosis. We used a published life-stage physiologically based pharmacokinetic (PBPK) model to simulate plasma levels of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) from birth to age at study participation (range 18-44years). In the simulated population, PFAS level distributions matched those for controls in the epidemiologic study. Prevalence and geometric mean duration (standard deviation [SD]) of oral contraceptive use in the simulated women were based on data from the National Health and Nutrition Examination Survey; among the women with endometriosis the values were, respectively, 29% and 6.8 (3.1) years; among those without endometriosis these values were 18% and 5.3 (2.8) years. In simulations, menstrual fluid loss (ml/cycle) in women taking oral contraceptives was assumed to be 56% of loss in non-users. We evaluated the association between simulated plasma PFAS concentration and endometriosis in the simulated population using logistic regression. Based on the simulations, the association between PFAS levels and endometriosis attributable to differential contraceptive use had an odds ratio (95% CI) of 1.05 (1.02, 1.07) for a log e unit increase in PFOA and 1.03 (1.02, 1.05) for PFOS. In comparison, the epidemiologic study reported odds ratios of 1.62 (0.99, 2.66) for PFOA and 1.25 (0.87, 1.80) for PFOS. Our results suggest that the influence of oral contraceptive use on the association between PFAS levels and endometriosis is relatively small. Copyright © 2017 Elsevier

Background Oral contraceptives (OCs) have been used as a first-line option for medical treatment in women with polycystic ovary syndrome (PCOS). Despite theoretical superiority of products containing antiandrogenic progestins compared to OCs containing levonorgestrel (LNG), the clinical advantage of these compounds remains unclear. Objective The aim of this study was to compare the effects of OCs containing LNG with products containing antiandrogenic progestins including cyproterone acetate, drospirenone, and desogestrel on clinical, hormonal, and metabolic parameters and quality of life in women with PCOS. Methods We conducted a 6-arm crossover randomized controlled trial with each arm including OCs containing LNG and one of those 3 OCs containing antiandrogenic progestins. The anthropometric and clinical manifestations and hormonal and biochemical parameters of participants were assessed at 6 time points including baseline, after washout period, and 3 and 6 months after intervention. Results The study is ongoing and follow-up of recruited women will continue until 2018. Conclusions This study will provide scientific evidence on comparability of OCs with the various progesterones that will assist in decision making taking into account cost effectiveness.

Full Text Available Serena Ferrari, Marianna Cannoletta, Matteo Generali, Lucia Cazzato, Angelo CagnacciDepartment of Obstetrics, Gynecology, and Pediatrics, Azienda Ospedaliero, Universitaria di Modena, ItalyAbstract: Since their introduction in 1959, development of hormonal contraceptives has been ongoing, with the ultimate aim of creating not only an effective and safe contraceptive method, but also a drug able to meet the need for treatment of other conditions, such as acne, seborrhea, and hirsutism, with few or no side effects. With this objective, a new progestin, chlormadinone acetate (CMA, has been developed as a derivative of progesterone for ­contraception. This new molecule has been introduced in combination with ethinylestradiol (EE 30 µg as a safe ­contraceptive with antiandrogenic properties. Many clinical studies have investigated this new oral combination and found it to be safe, with a Pearl Index similar to that of other combined hormonal contraceptives. CMA, because of its antiandrogenic properties, has been also considered effective for resolution of acne, seborrhea, and hirsutism. The data show it to be a safe molecule in terms of glucose and lipid metabolism. No major weight changes have been linked with its use, and it seems to be the only progestin able to reduce fat mass during use. The CMA-EE combination is well tolerated and acceptable to women. Adverse events related to its use are similar to those reported with other third-generation ­contraceptives. We can conclude that CMA-EE is an effective, safe, and well tolerated ­antiandrogenic hormonal contraceptive.Keywords: chlormadinone acetate, acne, weight, metabolism, safety, hormonal contraceptive

CUP: contraceptive users pamphlet.

Science.gov (United States)

1986-02-01

This pamphlet, edited by an ad hoc committee of several consultants, scientists, theologians, public health and family planning directors, and an international attorney, covers the following topics: contra-conception; choices of contraceptives; contraceptive package information; copper IUDs; pelvic inflammatory disease (PID); sexually transmitted diseases; and acquired immunodeficiency syndrome. It includes a questionnaire for sexually transmitted diseases (STDs). Professor Joseph Goldzieher describes the "Contra-Conception" database as "a synthesis of up-to-date literature and contemporary guidelines, designed to provide ready access for practicing physicians and medical students." It contains data on several types of hormonal contraception. "Contra-Conceptions" is designed to allow the physician to set his or her own pace when working with the computer, and no previous computer experience is required. 1 of the program's many innovative features is the patient-profiling/decisionmaking section which can be used in the doctor's office to help decide what type of hormonal contraceptive is appropriate for a particular patient. The program permits the doctor to evaluate the significance of patient variables such as parity, smoking, menstrual difficulties and helps the doctor to identify the risks and benefits of the various methods and, ultimately, to make a balanced decision in the context of the most recent data. Contraceptive drugs and devices should include detailed information on the following: description of formula or device; indication, usage, and contraindications, clinical pharmacology and toxicology; dose-related risk; pregnancies per 100 women year; and detailed warning. The sequence of major pathophysiological reactions associated with copper IUDs is identified as are special problems of pelvic infections in users of copper IUDs. Those women who use oral contraceptives (OCs) or a barrier method of contraception or whose partners use a condom have a lower

Practice Bulletin Summary No. 152: Emergency Contraception.

Science.gov (United States)

2015-09-01

Emergency contraception, also known as postcoital contraception, is therapy used to prevent pregnancy after an unprotected or inadequately protected act of sexual intercourse. Common indications for emergency contraception include contraceptive failure (eg, condom breakage or missed doses of oral contraceptives) and failure to use any form of contraception (1-3). Although oral emergency contraception was first described in the medical literature in the 1960s, the U.S. Food and Drug Administration (FDA) approved the first dedicated product for emergency contraception in 1998. Since then, several new products have been introduced. Methods of emergency contraception include oral administration of combined estrogen-progestin, progestin only, or selective progesterone receptor modulators and insertion of a copper intrauterine device (IUD). Many women are unaware of the existence of emergency contraception, misunderstand its use and safety, or do not use it when a need arises (4-6). The purpose of this Practice Bulletin is to review the evidence for the efficacy and safety of available methods of emergency contraception and to increase awareness of these methods among obstetrician-gynecologists and other gynecologic providers.

Adoption of contraceptive implants and intrauterine devices has been less than might be expected given their superior efficacy and convenience. The purpose of this study was to assess knowledge and beliefs held by women, which may influence their contraceptive choices and theirongoing utilization of contraceptive methods. English speaking, nonpregnant, reproductive-age women, who were not surgically sterilized, were individually interviewed to obtain limited demographic characteristics and to assess their knowledge about the efficacy of various contraceptive methods in typical use and about the relative safety of oral contraceptives. A convenience sample of 500 women aged 18-45 years, with education levels that ranged from middle school to postdoctoral level was interviewed. The efficacy in typical use of both combined oral contraceptives and male condoms was correctly estimated by 2.2%; over two-thirds of women significantly over estimated the efficacy of each of those methods in typical use. Oral contraceptives were thought to be at least as hazardous to a woman's health as pregnancy by 56% of women. The majority of reproductive aged women surveyed substantially overestimated the efficacy of the two most popular contraceptive methods, often saying that they were 99% effective. Women with higher education levels were most likely to overestimate efficacy of oral contraceptives. Women of all ages and education levels significantly overestimated the health hazards of oral contraceptives compared to pregnancy. Overestimation of effectiveness of these methods of contraception, may contribute to lower adoption of implants and intrauterine devices. When individualizing patient counselling, misperceptions must be identified and addressed with women of all educational backgrounds. Not applicable.

This study was conducted during the period from 15/01/04 to 24/04/04 at Sudan Fertility Care Association Center. Sixty nine Sudanese females using combined oral contraceptives were chosen for this study and twenty females not using contraceptives were used as controls. All individuals were within the same age group. Thyroid hormones; thyroxine (T 4 ), triiodothyronine (T 3 ), free thyroxine (FT 4 ) and free triiodothyronine (FT 3 ) were measured. In addition thyroid stimulating hormone (TSH) was also measured in both groups. The study groups were divided according to the period of using combined oral contraceptives into four groups group 1 (1-5) months, group 2 (7-16) months and group 3 (18-60) months and the control group of the non users. Determination of hormones concentrations were carried out using a highly sensitive specific radioimmunoassay (RIA) technique. The concentrations of serum T 4 in group 3 was significantly higher (P 4 in group 1 and 2 were found to be lower than in the control and the difference was not significant. Mean serum concentration of triiodothyronine in the study group 1, 2 and 3 were not significantly higher than the control group. Mean serum concentration of free triiodothyronine in the study groups 1, 2 and 3 were not significantly higher than the control group. Mean serum concentration of free thyroxine in the study group 1, 2 and 3 were not significantly higher than the control group. Mean serum concentration of TSH in groups 1, 2 and 3 were significantly (P<0.05) lower than in the control group.(Author)

Full Text Available Hugo Maia Jr, Clarice Haddad, Julio Casoy Centro de Pesquisa e Assistência em Reprodução Humana (CEPARH, Salvador, Bahia, BrazilObjective: Menstrual symptoms such as dysmenorrhea usually occur during the hormone-free interval in oral contraceptive users. Progestin withdrawal activates NF-κB transcription factor, which upregulates both vascular endothelial growth factor (VEGF and Cox-2 expression in the endometrium. The use of natural NF-κB inhibitors such as pycnogenol may block this response, improving dysmenorrhea.Patients and methods: Twenty-four patients with severe dysmenorrhea were allocated to one of two treatment groups. In Group A (n=13, women were treated with an oral contraceptive containing 15 µg of ethinyl estradiol and 60 mg of gestodene (Adoless® in a 24/4 regimen for three consecutive cycles. Women in Group B (n=11 used the same contraceptive regimen together with 100 mg of pycnogenol (Flebon® continuously for 3 months. Pain scores were graded using a visual analog scale (VAS before and during the hormone-free interval at the end of the third treatment cycle.Results: Before treatment, VAS pain scores for dysmenorrhea were 8 and 9 in Groups A and B, respectively. However, by the end of the third treatment cycle, pain scores had decreased significantly (P<0.05 both in groups A and B. The final pain scores were 6 in Group A and 2 in Group B, a difference that was statistically significant (P<0.0001. In Group B, 27% of the patients became pain-free, while in Group A, none of the women reported complete disappearance of this symptom. The number of bleeding days was also lower in Group B.Discussion: Pycnogenol effectively decreased pain scores and the number of bleeding days when administered concomitantly with a low-dose 24/4 oral contraceptive containing gestodene.Keywords: gestodene, hormone-free interval, pain

A consultation for emergency contraception (EC) gives way to an opportunity to provide women with an ongoing effective method of contraception. A review of the case notes of women seeking EC from a large family planning clinic in Edinburgh, Scotland, was conducted to determine what percentage of women were provided with an effective method of ongoing contraception. Case notes of 460 women presenting for EC over a 2-year period were reviewed. Women were of mean age 26 years (range 15-49 years) and presented because they had used no contraception (47%), experienced condom failure (42%) or missed oral contraceptive pills (9%). Only 2% (n=11) were given an intrauterine device for EC. All women who had missed contraceptive pills prior to taking EC opted to continue this method. Only 23% (n=89) of women using no method or condoms at EC received supplies of an effective contraceptive method (pills, patch, injectable). Two thirds (n=263) of the women chose condoms for ongoing contraception. Research is required to develop strategies to improve the uptake of effective contraception after EC.

The estrogen step-down/progestogen step-up 28-day estradiol valerate/dienogest (E(2)V/DNG) oral contraceptive effectively inhibits ovulation; however, limited data are available regarding its effects on estradiol (E2), progesterone, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) or its additional extraovarian contraceptive effects. In this secondary analysis, 100 women received E(2)V 3 mg on days 1-2, E(2)V 2 mg/DNG 2 mg on days 3-7, E(2)V 2 mg/DNG 3 mg on days 8-24, E(2)V 1 mg on days 25-26 and placebo on days 27-28 for one treatment cycle. Measures included the presence/absence of cervical mucus; endometrial thickness; and serum E2, progesterone, and gonadotropin levels. E2, progesterone, LH and FSH levels did not exhibit the typical ovulatory increase and remained relatively stable during the cycle. E(2)V/DNG reduced mean maximal endometrial thickness and proportion of women with visible cervical mucus. All parameters returned to pretreatment levels during the posttreatment cycle. E(2)V/DNG provides extraovarian contraceptive effects (reducing endometrial thickness and cervical mucus production) in addition to inhibiting ovulation, assuring contraceptive efficacy.

To assess the level of risk for adolescents and women who seek emergency contraception through various clinical routes and the opportunities for improved care provision. This study looked at a retrospective cohort to assess contraception and other reproductive health outcomes among adolescents and women aged 15-44 years who accessed oral levonorgestrel emergency contraception through an office visit or the call center at Kaiser Permanente Northern California from 2010 to 2011. Of 21,421 prescriptions, 14,531 (67.8%) were accessed through the call center. In the subsequent 12 months, 12,127 (56.6%) adolescents and women had short-acting contraception (pills, patches, rings, depot medroxyprogesterone) dispensed and 2,264 (10.6%) initiated very effective contraception (intrauterine contraception, implants, sterilization). Initiation of very effective contraception was similar for adolescents and women who accessed it through the call center-1,569 (10.8%) and office visits-695 (10.1%) (adjusted odds ratio [OR] 1.02, 95% confidence interval [CI] 0.93-1.13). In the subsequent 6 months, 2,056 (9.6%) adolescents and women became pregnant. Adolescents and women who accessed emergency contraception through the call center were less likely to become pregnant within 3 months of accessing emergency contraception than woman who accessed it through office visits (adjusted OR 0.82, 95% CI 0.72-0.94); however, they were more likely to become pregnant within 4-6 months (adjusted OR 1.37, 95% CI 1.16-1.60). Among adolescents and women who were tested for chlamydia and gonorrhea, 689 (7.8%) and 928 (7.9%) were positive in the 12 months before and after accessing emergency contraception, respectively. Protocols to routinely address unmet needs for contraception at every call for emergency contraception and all office visits, including visits with primary care providers, should be investigated.

Objective To estimate the effect of progestin-only vs. combined hormonal contraceptive pills on rates of breastfeeding continuation in postpartum women. Secondary outcomes include infant growth parameters, contraceptive method continuation and patient satisfaction with breastfeeding and contraceptive method. Methods In this randomized controlled trial, postpartum breastfeeding women who desired oral contraceptives were assigned to progestin-only vs. combined hormonal contraceptive pills. At two and eight weeks postpartum, participants completed in-person questionnaires that assessed breastfeeding continuation and contraceptive use. Infant growth parameters including weight, length and head circumference were assessed at eight weeks postpartum. Telephone questionnaires assessing breastfeeding, contraceptive continuation and satisfaction were completed at 3-7 weeks and 4 and 6 months. Breastfeeding continuation was compared between groups using Cox proportional hazards regression. Differences in baseline demographic characteristics and in variables between the two intervention groups were compared using chi-square tests, Fisher’s Exact test, or two-sample t-tests as appropriate. Results Breastfeeding continuation rates, contraceptive continuation, and infant growth parameters did not differ between users of progestin-only and combined hormonal contraceptive pills. Infant formula supplementation and maternal perception of inadequate milk supply were associated with decreased rates of breastfeeding in both groups. Conclusions Choice of combined or progestin-only birth control pills administered two weeks postpartum did not adversely affect breastfeeding continuation. PMID:22143258

Findings about sex differences in the field of fear conditioning and fear extinction have been mixed. At the psychophysiological level, sex differences emerge only when taking estradiol levels of women into consideration. This suggests that this hormone may also influence sex differences with regards to activations of brain regions involved in fear conditioning and its extinction. Importantly, the neurobiological correlates associated with the use of hormonal oral contraceptives in women have not been fully contrasted against men and against naturally cycling women with different levels of estradiol. In this study, we begin to fill these scientific gaps. We recruited 37 healthy men and 48 healthy women. Of these women, 16 were using oral contraceptives (OC) and 32 were naturally cycling. For these naturally cycling women, a median split was performed on their serum estradiol levels to create a high estradiol (HE) group (n = 16) and a low estradiol (LE) group (n = 16). All participants underwent a 2-day fear conditioning and extinction paradigm in a 3 T MR scanner. Using the 4 groups (men, HE women, LE women, and OC users) and controlling for age and coil type, one-way ANCOVAs were performed to look at significant activations within the nodes of the fear circuit. Using post-hoc analyses, beta-weights were extracted in brain regions showing significant effects in order to unveil the differences based on hormonal status (men, HE, LE, OC). Significant main effect of hormonal status group was found across the different phases of the experiment and in different sub-regions of the insular and cingulate cortices, amygdala, hippocampus, and hypothalamus. During conditioning, extinction and recall, most of the observed differences suggested higher activations among HE women relative to men. During the unconditioned response, however, a different pattern was observed with men showing significantly higher brain activations. Our data further support the important contribution

To determine the relationship between the use of combined oral contraceptives (COCs) and sexual desire based on a systematic review of the literature. MEDLINE Complete, Google Scholar and the Cochrane Library were searched for articles published between 1975 and 2011, reporting the effects of oral contraceptives on sexual desire. Reports fully meeting all the predefined criteria were analysed and included in a final reference list. In addition, a review of the reference list of selected articles was carried out. We evaluated 36 studies (1978-2011; 13,673 women). Of the COC users (n = 8,422), 85% reported an increase (n = 1,826) or no change (n = 5,358) in libido and 15% reported a decrease (n = 1,238). We found no significant difference in sexual desire in the case of COCs with 20-35 μg ethinylestradiol; libido decreased only with pills containing 15 μg ethinylestradiol. The majority of COC users report no significant change in libido although in most studies a decline in plasma levels of free testosterone and an increase in those of sex hormone binding globulin were observed.

Full Text Available Background: Polycystic ovary syndrome (PCOS is one of the common endocrine disorders in women of reproductive ages. It is associated with a range of disorders, such as dyslipidemia, hypertension, insulin resistance (IR, compensatory hyperinsulinemia, gestational, and type 2 diabetes, and increased risk of cardiovascular morbidity. There are different treatments available for PCOS. The purpose of this study was to determine and compare the effects of metformin, flutamide plus oral contraceptives (OCs, and simvastatin on the metabolic consequences of PCOS. Materials and Methods: This study was a single-blind clinical trial. The subjects were selected from a group of patient with PCOS and metabolic syndrome, who were referred to the midwifery clinic of Al-Zahra Hospital and Beheshti Hospital, Isfahan, Iran. A total of 111 subjects were randomly assigned to three groups: metformin, flutamide plus OCs, and simvastatin groups. The measurements were performed at baseline and after 6 months of therapy. Paired t-test, analysis of variance (ANOVA, and chi-square test were applied in this study. Results: A total of 102 subjects were analyzed in this study, 34 subjects were allotted in each group. The prevalence of IR was statistically different between three groups (P-value = 0.001. After a 6-month course, metformin showed larger reduction in fasting blood sugar (FBS level (P-value 0.05. Conclusion: Metformin performed better in FBS reduction. Simvastatin had better performance in terms of reducing TG level and waist circumference.

Most women on combined oral contraceptives (COC) report high levels of satisfaction, but 4-10% complain of adverse mood effects. The aim of this randomized, double-blinded, placebo-controlled trial was to investigate if COC use would induce more pronounced mood symptoms than placebo in women with previous history of COC-induced adverse mood. A second aim was to determine if COC use is associated with changes in brain reactivity in regions previously associated with emotion processing. Thirty-four women with previous experience of mood deterioration during COC use were randomized to one treatment cycle with a levonorgestrel-containing COC or placebo. An emotional face matching task (vs. geometrical shapes) was administered during functional magnetic resonance imaging (fMRI) prior to and during the COC treatment cycle. Throughout the trial, women recorded daily symptom ratings on the Cyclicity Diagnoser (CD) scale. During the last week of the treatment cycle COC users had higher scores of depressed mood, mood swings, and fatigue than placebo users. COC users also had lower emotion-induced reactivity in the left insula, left middle frontal gyrus, and bilateral inferior frontal gyri as compared to placebo users. In comparison with their pretreatment cycle, the COC group had decreased emotion-induced reactivity in the bilateral inferior frontal gyri, whereas placebo users had decreased reactivity in the right amygdala. COC use in women who previously had experienced emotional side effects resulted in mood deterioration, and COC use was also accompanied by changes in emotional brain reactivity. These findings are of relevance for the understanding of how combined oral contraceptives may influence mood. Placebo-controlled fMRI studies in COC sensitive women could be of relevance for future testing of adverse mood effects in new oral contraceptives. Copyright © 2012 Elsevier Ltd.

The fertility rate in women with polycystic ovary disease (PCOD) is influenced by the type of treatment received. The present study evaluated the possible correlation between treatment and pulsatile release of gonadotropins. Spontaneous episodic secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) and hormonal parameters were monitored before and after 1, 3, and 6 months after treatments suspension. Twenty-four PCOD patients were randomly divided into two groups of 12 subjects. Group A was treated with gonadotropin-releasing hormone (GnRH)-analogue plus oral contraceptive (OC). Group B was treated only with OC. Both groups were treated for 6 months and followed up for 6 months. In all subjects the therapeutic regimens reduced the androgenic milieau and the gonadotropin plasma levels. Spontaneous pulsatile secretion of LH and FSH was significantly modified in both groups, but patients who received the combined regimen showed a significantly greater reduction of LH plasma levels and a significantly greater decrease of LH pulse amplitude throughout the 6 months after treatment suspension. Ferriman-Gallway score and ovarian volumes were significantly reduced in patients who received the combined treatment than in the OC-treated patients. These data support the evidence of a higher efficacy of the combination of GnRH-a + OC than OC alone in restoring a normal and adequate spontaneous episodic gonadotropin discharge and in decreasing Ferriman-Gallway score and ovarian volumes in patients with PCOD.

The introduction of a new progestin-only oral contraceptive in Europe has renewed interest in this class of oral contraceptives. Unlike the more widely used combined oral contraceptives containing an estrogen plus progestin, these pills contain only a progestin (progestogen) and are taken without interruption. How these pills compare to others in their class or to combined oral contraceptives is not clear. This review examined randomized controlled trials of progestin-only pills for differences in efficacy, acceptability, and continuation rates. Through October 2013, we searched the computerized databases MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), POPLINE, and LILACS for studies of progestin-only pills. We also searched for current trials via ClinicalTrials.gov and ICTRP. Previous searches also included EMBASE. We included all randomized controlled trials in any language that included progestin-only pills for contraception.  We incorporated any comparison with a progestin-only pill; this could include different doses, other progestin-only pills, combined oral contraceptives, or other contraceptives. The first author abstracted the data and entered the information into RevMan 5. Another author performed a second, independent data abstraction to verify the initial data entry.We attempted to extract life-table rates (actuarial or continuous) and used the rate difference as the effect measure. Where life-table rates were not published, we used the incidence rate ratio (ratio of Pearl rates). Where only the crude number of events was published, we calculated the Peto odds ratio with 95% confidence interval (CI) using a fixed-effect model. For continuous variables, the mean difference (MD) was computed with 95% CI. Because of disparate exposures, we were not able to combine studies in meta-analysis. Six trials met the inclusion criteria. We have not found any new studies since the initial review. In the trial comparing the desogestrel versus

The provision of effective contraception is fundamental to the practice of women's health care. The most effective methods of reversible contraception are the so-called long-acting reversible contraceptives, intrauterine devices and implants. These methods have multiple advantages over other reversible methods. Most importantly, once in place, they do not require maintenance and their duration of action is long, ranging from 3 to 10 years. Despite the advantages of long-acting reversible contraceptive methods, they are infrequently used in the United States. Short-acting methods, specifically oral contraceptives and condoms, are by far the most commonly used reversible methods. A shift from the use of short-acting methods to long-acting reversible contraceptive methods could help reduce the high rate of unintended pregnancy in the United States. In this review of long-acting reversible contraceptive methods, we discuss the intrauterine devices and the contraceptive implant available in the United States, and we describe candidates for each method, noncontraceptive benefits, and management of complications.

The mean age of first sexual intercourse is still around 17 in France, but a lot of teenagers are concerned by contraception before, with approximately 25% of sexually active 15-year-old girls. The contraceptive method must take into consideration some typical features of this population, as sporadic and non-planned sexual activity, with several sexual partners in a short period of time. In 2004, the "Haute Autorité de santé" has recommended, as first-line method, combined oral contraceptive (COC) pills, in association with male condoms. Copper-containing intrauterine contraceptive devices (IUCD) and etonogestrel-containing subcutaneous implant have been suggested but not recommended. However, oral contraceptive pill, as a user-based method, carries an important typical-use failure rate, because remembering taking a daily pill, and dealing with stop periods, may be challenging. Some easier-to-use method should be kept in mind, as 28-day COC packs, transdermal contraceptive patches, and vaginal contraceptive rings. Moreover, American studies have shown that long-acting reversible contraceptives (LARC), i.e. IUCD and implant, have many advantages for teenagers: very effective, safe, invisible. They seem well-fitted for this population, with high satisfaction and continuation rates, as long as side effects are well explained. Thus, LARC methods should be proposed more widely to teenagers. Anyway, before prescribing a contraceptive method, it is important to determine the specific situation of every teenager, to let them choose the method that they consider as appropriate in their own case, and to think about the availability of the chosen method. It is necessary to explain how to handle mistakes or misses with user-based contraceptive methods, and emergency contraception can be anticipated and prescribed in advanced provision. The use of male condoms should be encouraged for adolescents, with another effective contraceptive method, in order to reduce the high risk

Medicaid spending on contraceptive coverage and pregnancy-related care

Science.gov (United States)

2014-01-01

Objective Up to 50% of pregnancies are unintended in the United States, and the healthcare costs associated with pregnancy are the most expensive among hospitalized conditions. The current study aims to assess Medicaid spending on various methods of contraception and on pregnancy care including unintended pregnancies. Methods We analyzed Medicaid health claims data from 2004 to 2010. Women 14–49 years of age initiating contraceptive methods and pregnant women were included as separate cohorts. Medicaid spending was summarized using mean all-cause and contraceptive healthcare payments per patient per month (PPPM) over a follow-up period of up to 12 months. Medicaid payments were also estimated in 2008 per female member of childbearing age per month (PFCPM) and per member per month (PMPM). Medicaid payments on unintended pregnancies were also evaluated PFCPM and PMPM in 2008. Results For short-acting reversible contraception (SARC) users, all-cause payments and contraceptive payments PPPM were respectively $365 and $18.3 for oral contraceptive (OC) users, $308 and $19.9 for transdermal users, $215 and $21.6 for vaginal ring users, and $410 and $8.8 for injectable users. For long-acting reversible contraception (LARC) users (follow-up of 9–10 months), corresponding payments were $194 and $36.8 for IUD users, and $237 and $29.9 for implant users. Pregnancy cohort all-cause mean healthcare payments PPPM were $610. Payments PFCPM and PMPM for contraceptives were $1.44 and $0.54, while corresponding costs of pregnancies were estimated at $39.91 and $14.81, respectively. Payments PFCPM and PMPM for contraceptives represented a small fraction at 6.56% ($1.44/$21.95) and 6.63% ($0.54/$8.15), respectively of the estimated payments for unintended pregnancy. Conclusions This study of a large sample of Medicaid beneficiaries demonstrated that, over a follow-up period of 12 months, Medicaid payments for pregnancy were considerably higher than payments for either SARC or

Effect of low zinc intake and oral contraceptive agents on nitrogen utilization and clinical findings in young women.

Hess, F M; King, J C; Margen, S

1977-12-01

In a previous paper we reported that serum, urine and fecal zinc levels fell markedly in women taking a combination oral contraceptive agent (+OCA) and in women with normal menstrual cycles (-OCA) when they consumed a low-zinc diet (less than 0.2 mg/day) for 35 days. We evaluated other biochemical and clinical data in order to determine if depletion of accessible body zinc and/or physiologic adjustment to conserve body zinc stores had occurred. Neither low zinc intake nor oral contraceptive use appeared to influence nitrogen balance or body weight. Use of contraceptive drugs appeared to influence the response of blood parameters to zinc depletion. Serum transferrin and cholesterol declined significantly in the -OCA group, whereas alkaline phosphatase and gamma-globulin changed significantly in both groups. Clinical problems developed in all the subjects with serum zinc levels below 50 microgram/dl during the study; three of the six with serum zinc levels above 50 microgram/dl also complained of clinical symptoms. The results suggest that zinc deficiency through depletion of accessible body zinc stores developed during the 35-day study.

The Affordable Care Act (ACA) mandated that, starting between August 1, 2012 and July 31, 2013, health plans cover most Food and Drug Administration (FDA)-approved contraceptive methods for women without cost sharing. This study examined the impact of the ACA on out-of-pocket expenses for contraceptives. Women (ages 15-44years) with claims for any contraceptives in years 2011, 2012 and 2013 were identified from the MarketScan Commercial database. The proportions of women using contraceptives [including permanent contraceptives (PCs) and non-PCs: oral contraceptives (OCs), injectables, patches, rings, implants and intrauterine devices (IUDs)] in study years were determined, as well as changes in out-of-pocket expenses for contraceptives during 2011-2013. Demographics, including age, U.S. geographic region of residence and health plan type, were also evaluated. The number of women identified with any contraceptive usage in 2011 was 2,447,316 (mean age: 27.6years), in 2012 was 2,515,296 (mean age: 27.4years) and in 2013 was 2,243,253 (mean age: 27.4years). In 2011, 2012 and 2013, the proportions of women with any contraceptive usage were 26.3%, 26.2% and 26.9%, respectively. Over the three study years, mean total out-of-pocket expenses for PCs and non-PCs decreased from $298 to $82 and from $94 to $30, respectively. For non-PCs, mean total out-of-pocket expenses for OCs and IUDs decreased from $86 to $26 and from $83 to $20. Implementation of the ACA has saved women a substantial amount in out-of-pocket expenses for contraceptives. Mean total out-of-pocket expenses for FDA-approved contraceptives decreased approximately 70% from 2011 to 2013. Implementation of the ACA has saved women a substantial amount in out-of-pocket expenses for contraceptives. Longer-term studies, including clinical outcomes, are warranted.

A 40-year-old woman experiencing sudden dyspnea went to her personal doctor for advice. She was previously diagnosed with endometriosis and prescribed oral contraceptives for treatment. During earthquakes, she spent 7 nights sleeping in a vehicle. The patient had swelling and pain in her left leg and high D-dimer concentration levels. A contrast-enhanced computed tomography scan revealed a contrast deficit in the bilateral pulmonary artery and in the left lower extremity. She was diagnosed with pulmonary thromboembolism (PTE), and anticoagulation therapy was initiated. This present case is the first report of PTE attributed to the use of oral contraceptives after earthquakes.

Ischemic stroke occurring during intercourse in young patients is exceedingly rare. We present 2 cases of young women taking oral contraceptives, each presenting with an ischemic stroke. Transthoracic echocardiography revealed a patent foramen ovale in one patient and an atrial septal defect in the other. The most likely cause of stroke in both patients is embolic. Despite conflicting evidence, young patients presenting with ischemic stroke and found to have a patent foramen ovale or atrial septal defect should be considered for possible device-based closure.

The aim of this survey was to understand US women's contraception journey from her first prescribed method to her current one including reasons for choosing and stopping/switching methods, healthcare provider relationships, and bleeding preferences. We administered a nationally-representative, web-based survey of US women aged 16 to 50 years currently using (N=1656) or had previously used (N=1448) prescription contraception, or who had never used it but would consider using it in the future (N=103). Statistical analyses were based on overlap formulae with sample weights adjusted to 2010 US census demographic benchmarks. The survey was sent to 11,906 women, and 5957 responded (50% response rate). Among qualified respondents, 3104 had experience with prescription contraception. Oral contraceptives (OC) remain the most frequently prescribed method as first or subsequent contraception. However, as women switch to their current prescription method, more chose IUD contraception. As reported by respondents, only 48% of current users received counseling on how to use specific methods, and 58% were counseled on bleeding patterns to expect, while 67% were offered counseling on potential side effects. Many of the side effects reported in this study for first and current prescription contraception were nonspecific and may be related to a nocebo effect, lack of understanding about normal bodily fluctuations, or poor compliance. Many women (34%) reported 'making their periods lighter' as a reason for using their current prescription method, and 53% would prefer to skip their monthly period altogether. Misperceptions about contraception are common, and prescription contraception choice can be quite complex. Clinicians can enhance patient satisfaction by providing adequate information and matching methods to women's lifestyles, reproductive choices, and pregnancy risk. This study provides insight into modern women's attitudes and views toward prescription contraception that may be

Modification by oral contraceptives in rat of 14C acetate incorporation into platelet lipids

International Nuclear Information System (INIS)

Ciavatti, M.; Renaud, S.

1979-01-01

The in vitro incorporation of acetate 14 C in platelet lipids was compared in control female rats (Gr.I) to rats treated for 4 days either by an oral contraceptive ethinyl oestradiol + lynestrenol (Gr.II), or by ethinyl oestradiol alone (Gr.III) or lynestrenol alone (Gr.IV). An increase of 43-45% in the incorporation of acetate could be ovserved in the two groups (II and III) which received ethinyl oestradiol, while the incorporation in group IV was similar to that of the controls. The lipid fractions of which the synthesis was the most considerably stimulated by the oestrogen treatment, were the neutral lipids as separated from the other lipids by TLC. In groups II and III the incorporation in cholesterol and cholesterol esters was increased by 8 fold and by 10 fold in the free fatty acid fraction. In these two groups, even in the phospholipid fractions PS + PI and PE, the radioactivity was significantly increased. The observed effect of the oral contraceptive studied here on platelet lipid synthesis in female rats, appears to be essentially due to the estrogens, since lynestrenol had only minimal effects in that respect.

The copper intrauterine device is the most effective form of emergency contraception and can also provide long-term contraception. The levonorgestrel intrauterine device has also been studied in combination with oral levonorgestrel for women seeking emergency contraception. However, intrauterine devices have higher up-front costs than oral methods, such as ulipristal acetate and levonorgestrel. Health care payers and decision makers (eg, health care insurers, government programs) with financial constraints must determine if the increased effectiveness of intrauterine device emergency contraception methods are worth the additional costs. We sought to compare the cost-effectiveness of 4 emergency contraception strategies-ulipristal acetate, oral levonorgestrel, copper intrauterine device, and oral levonorgestrel plus same-day levonorgestrel intrauterine device-over 1 year from a US payer perspective. Costs (2017 US dollars) and pregnancies were estimated over 1 year using a Markov model of 1000 women seeking emergency contraception. Every 28-day cycle, the model estimated the predicted number of pregnancy outcomes (ie, live birth, ectopic pregnancy, spontaneous abortion, or induced abortion) resulting from emergency contraception failure and subsequent contraception use. Model inputs were derived from published literature and national sources. An emergency contraception strategy was considered cost-effective if the incremental cost-effectiveness ratio (ie, the cost to prevent 1 additional pregnancy) was less than the weighted average cost of pregnancy outcomes in the United States ($5167). The incremental cost-effectiveness ratios and probability of being the most cost-effective emergency contraception strategy were calculated from 1000 probabilistic model iterations. One-way sensitivity analyses were used to examine uncertainty in the cost of emergency contraception, subsequent contraception, and pregnancy outcomes as well as the model probabilities. In 1000 women

To provide evidence-based guidance for women and their health care providers on the management of missed or delayed hormonal contraceptive doses in order to prevent unintended pregnancy. Medline, PubMed, and the Cochrane Database were searched for articles published in English, from 1974 to 2007, about hormonal contraceptive methods that are available in Canada and that may be missed or delayed. Relevant publications and position papers from appropriate reproductive health and family planning organizations were also reviewed. The quality of evidence is rated using the criteria developed by the Canadian Task Force on Preventive Health Care. This committee opinion will help health care providers offer clear information to women who have not been adherent in using hormonal contraception with the purpose of preventing unintended pregnancy. The Society of Obstetricians and Gynaecologists of Canada. SUMMARY STATEMENTS: 1. Instructions for what women should do when they miss hormonal contraception have been complex and women do not understand them correctly. (I) 2. The highest risk of ovulation occurs when the hormone-free interval is prolonged for more than seven days, either by delaying the start of combined hormonal contraceptives or by missing active hormone doses during the first or third weeks of combined oral contraceptives. (II) Ovulation rarely occurs after seven consecutive days of combined oral contraceptive use. (II) RECOMMENDATIONS: 1. Health care providers should give clear, simple instructions, both written and oral, on missed hormonal contraceptive pills as part of contraceptive counselling. (III-A) 2. Health care providers should provide women with telephone/electronic resources for reference in the event of missed or delayed hormonal contraceptives. (III-A) 3. In order to avoid an increased risk of unintended pregnancy, the hormone-free interval should not exceed seven days in combined hormonal contraceptive users. (II-A) 4. Back-up contraception should

We assessed intrauterine device (IUD) preference among women presenting for emergency contraception (EC) and the probability of pregnancy among concurrent oral levonorgestrel (LNG) plus LNG 52 mg IUD EC users. We offered women presenting for EC at a single family planning clinic the CuT380A IUD (copper IUD) or oral LNG 1.5 mg plus the LNG 52 mg IUD. Two weeks after IUD insertion, participants reported the results of a self-administered home urine pregnancy test. The primary outcome, EC failure, was defined as pregnancies resulting from intercourse occurring within five days prior to IUD insertion. One hundred eighty-eight women enrolled and provided information regarding their current menstrual cycle and recent unprotected intercourse. Sixty-seven (36%) chose the copper IUD and 121 (64%) chose oral LNG plus the LNG IUD. The probability of pregnancy two weeks after oral LNG plus LNG IUD EC use was 0.9% (95% CI 0.0-5.1%). The only positive pregnancy test after treatment occurred in a woman who received oral LNG plus the LNG IUD and who had reported multiple episodes of unprotected intercourse including an episode more than 5 days prior to treatment. Study participants seeking EC who desired an IUD preferentially chose oral LNG 1.5 mg with the LNG 52 mg IUD over the copper IUD. Neither group had EC treatment failures. Including the option of oral LNG 1.5 mg with concomitant insertion of the LNG 52 mg IUD in EC counseling may increase the number of EC users who opt to initiate highly effective reversible contraception. Consideration should be given to LNG IUD insertion with concomitant use of oral LNG 1.5 mg for EC. Use of this combination may increase the number of women initiating highly effective contraception at the time of their EC visit. Copyright © 2016 Elsevier Inc. All rights reserved.

It is estimated that in the year 2012, almost 213 million pregnancies occurred, and the global pregnancy rate decreased only slightly from 2008 to 2012. It was also estimated that 85 million pregnancies (40% of all pregnancies were unintended and that 38% ended in an unintended birth. Objectives: To assess knowledge and attitudes of Latin American (LA obstetricians and gynecologists (OBGYNs regarding unintended pregnancies and aspects of combined oral contraceptive (COC use. Methods: A survey was conducted during a scientific meeting about contraception in 2014, in which OBGYNs from 12 LA countries who provide attention in contraception were invited to respond to a multiple-choice questionnaire to assess their knowledge and attitudes regarding unplanned pregnancy and some aspects regarding COC use. Results: A total of 210 OBGYNs participated in the study. Their knowledge regarding COC failure was low. The participants reported they believed that their patients habitually forgot to take a pill and that their patients did not know what to do in these situations. They were aware of the benefits of COC use; however, they were less prone to prescribe COCs for the purpose of protecting against ovarian and endometrial cancer, and one-quarter of them had doubts about the association between COC use and cancer risk. Conclusion: The interviewed LA OBGYNs showed some flaws in terms of knowledge of COC failure rates and the non-contraceptive benefits and risks

Adverse mood symptoms with oral contraceptives.

In spite of combined oral contraceptives (COCs) having been available for more than 50 years, surprisingly little is known about the prevalence of truly COC-related adverse mood symptoms and about the underlying biological mechanisms of proposed changes in mood and affect. Precise estimates of COC-related adverse mood symptoms are not available due to the lack of placebo-controlled trials. In prospective trials the frequency of women who report deteriorated mood or deteriorated emotional well-being varies between 4 and 10%, but it can be assumed that the causal relation in these prevalence rates is overestimated. Adverse mood symptoms and somatic symptoms are most pronounced during the pill-free interval of the treatment cycles, but whether extended COC regimens would be more favorable in this respect is not known. COCs with anti-androgenic progestagens, such as drospirenone and desogestrel, appear more favorable in terms of mood symptoms than progestagens with a more androgenic profile. Available data suggest that lower doses of ethinylestradiol could be beneficial. © 2012 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.

Contraceptive social marketing in Albania - the NESMARK story.

Science.gov (United States)

Paravani, Ardian; Orgocka, Aida

2013-06-01

To present the history of social marketing of modern contraceptives in Albania. We review documentation and activity of NESMARK, an Albanian non-governmental social marketing organisation, and national data on adoption of modern contraception. During 15 years of awareness raising, sales of affordable products, and provider training, NESMARK has impacted the introduction and adoption of modern contraception in Albania. NESMARK is the country's main distributor of emergency contraception (EC) and complements the public sector in the distribution of condoms and oral contraceptives. NESMARK has made major efforts to overcome prevalent taboos and misinformation held by medical and nursing personnel, pharmacists and the general public, regarding the effectiveness and safety of condoms, oral contraceptives, and EC. NESMARK has contributed to increasing the choices for modern contraception methods in Albania by providing affordable contraceptives, training providers, and educating the general population. However, widespread use of withdrawal coupled with the belief that it is as or more effective than modern contraception, continues to limit uptake of new methods and is a significant challenge to comprehensive and sustained social marketing programmes.

Noncontraceptive use of oral combined hormonal contraceptives in polycystic ovary syndrome-risks versus benefits.

Science.gov (United States)

Dokras, Anuja

2016-12-01

The use of steroid sex hormones for noncontraceptive benefits has been endorsed by several medical societies. In women with polycystic ovary syndrome (PCOS), hormonal contraceptives are first-line therapy for concurrent treatment of menstrual irregularity, acne, and hirsutism. The association of PCOS with obesity, diabetes, and dyslipidemia frequently brings up the debate regarding risks versus benefits of hormonal contraceptives in this population. In women with PCOS, the lack of large-scale studies evaluating the risks with varying doses of ethinyl estradiol, types of progestins, and presence of confounding factors such as obesity, smoking, and other cardiometabolic comorbidities is a significant limitation in these deliberations. Although it is important to assess the absolute risk for major morbidities including cardiovascular events, currently, there are a paucity of long-term data for these outcomes in PCOS. Most of the current studies do not suggest an increase in risk of prediabetes/diabetes, clinically significant dyslipidemia, inflammatory changes, or depressive/anxiety symptoms with oral contraceptive pill use. Screening of women with PCOS for cardiometabolic and psychiatric comorbidities is routinely recommended. This information should be used by health care providers to individualize the choice of hormonal contraceptive treatment, adequately counsel patients regarding risks and benefits, and formulate an appropriate follow-up plan.

Growth and electrical characterization of Zn-doped InAs and InAs1-xSbx

International Nuclear Information System (INIS)

Venter, A.; Shamba, P.; Botha, L.; Botha, J.R.

2009-01-01

The electrical properties of Zn doped InAs and InAsSb layers grown on semi-insulating GaAs by metal organic vapour phase epitaxy, using dimethyl zinc as the p-type dopant source, have been studied. The influence of dopant flow rate, V/III ratio and substrate orientation on the electrical properties of these InAs and InAs 1-x Sb x layers have been studied at a few appropriate growth temperatures. A promising group V source, tertiary butyl arsenic was used as an alternative to arsenic hydride in the case of InAs growth. The electrical properties of the InAs and InAs 1-x Sb x epitaxial layers were mainly studied by the Hall effect. However, surface accumulation in these materials results in deceptive Hall results being extracted. A two layer model (assuming the layer to consist of two parallel conducting paths viz. surface and bulk) has therefore been used to extract sensible transport properties. In addition, conventional Hall measurements ignores the high electron to hole mobility ratio in InAs and InAsSb leading to erroneous transport properties.

Obesity and hormonal contraceptive efficacy.

Robinson, Jennifer A; Burke, Anne E

2013-09-01

Obesity is a major public health concern affecting an increasing proportion of reproductive-aged women. Avoiding unintended pregnancy is of major importance, given the increased risks associated with pregnancy, but obesity may affect the efficacy of hormonal contraceptives by altering how these drugs are absorbed, distributed, metabolized or eliminated. Limited data suggest that long-acting, reversible contraceptives maintain excellent efficacy in obese women. Some studies demonstrating altered pharmacokinetic parameters and increased failure rates with combined oral contraceptives, the contraceptive patch and emergency contraceptive pills suggest decreased efficacy of these methods. It is unclear whether bariatric surgery affects hormonal contraceptive efficacy. Obese women should be offered the full range of contraceptive options, with counseling that balances the risks and benefits of each method, including the risk of unintended pregnancy.

Visual Analogue Scale (VAS) score for dysmenorrhea, Short Form-36 questionnaire for health-related quality of life, lipoproteins and days of menstrual bleeding (withdrawal bleeding during oral contraceptive). Mean age and body mass index (BMI) were similar between the two groups. The final analysis was performed on 34 women, 15 in E2/NOMAC and 19 in EE/CMA group. Compliance with treatment was significantly higher with EE/CMA (100%) than E2/NOMAC (75%) (p = 0.02). Both treatments significantly (p dysmenorrhea, similarly (E2/NOMAC by a mean of 74.7%, EE/CMA by a mean of 78.4%; p = 0.973). Only E2/NOMAC significantly increased SF-36 score (p = 0.001), both in physical (p = 0.001) and mental domains (p = 0.004). The mean number of days of menstrual bleeding was significantly reduced in E2/NOMAC group (from 4.86 ± 1.20 d to 2.64 ± 1.59 d, p = 0.0005 versus baseline, p = 0.007 versus EE/CMA group). BMI did not vary in either group. E2/NOMAC did not change lipoproteins and apoproteins while EE/CMA increased total cholesterol (p = 0.0114), HDL-cholesterol (p = 0.0008), triglycerides (p = 0.002), apoprotein-A1 (Apo-A1; p = 0.0006) and apopoprotein-B (Apo-B; p = 0.008), decreasing LDL/HDL ratio (p = 0.024). Both oral contraceptives reduced similarly primary dysmenorrhea, with E2/NOMAC also reducing withdrawal bleedings and being neutral on lipid metabolism.

In the 1980s and 1990s, the litigious climate in the US had a catastrophic effect on sales of many major contraceptives. Although oral contraceptives escaped controversy, the intrauterine device (IUD) and Norplant(R) were two targets of damaging litigation. The IUD was withdrawn from the market in 1985. Since 1994 when the attacks began against Norplant, its US sales have dramatically declined, even though no fault has been found in the method or its development. In general, pharmaceutical companies were extremely hesitant to develop new contraceptives during this period. The bleak outlook, however, began to shift in the late 1990s, as fertility rates began to decrease worldwide and contraceptive users increased. By 2025, 2500 million women will comprise the customer base for contraception. Global pharmaceutical companies are now participating in expanding markets overseas and have launched and continue to develop a range of new long-term reversible, and highly effective, contraceptive products outside the traditional oral contraceptive field. Two new contraceptives on the way to the US market are: Mirena, a levonorgestrel-releasing intrauterine system manufactured by Schering-Leiras; and Implanon, a single implant system manufactured by Organon of the Netherlands. Other birth control methods soon to be launched include: emergency contraceptives, the contraceptive patch, monthly contraceptive injections, mifepristone for medical abortion, and modified oral contraceptives.

An update on emergency contraception.

Emergency contraception decreases the risk of unintended pregnancy after unprotected sexual intercourse or after suspected failure of routine contraception (e.g., a condom breaking). Oral methods include combined contraceptive pills (i.e., Yuzpe method), single- or split-dose levonorgestrel, and ulipristal. The Yuzpe method and levonorgestrel are U.S. Food and Drug Administration-approved for use 72 hours postcoitus, whereas the newest method, ulipristal, is approved for up to 120 hours postcoitus. The copper intrauterine device may be used as emergency contraception up to seven days after unprotected intercourse. It is nonhormonal and has the added benefit of long-term contraception. Advanced provision of emergency contraception may be useful for all patients, and for persons using ulipristal because it is available only by prescription. Physicians should counsel patients on the use and effectiveness of emergency contraception, the methods available, and the benefits of routine and consistent contraception use.

Cancer is one of the main public health issues in the world. Breast cancer is one of the most common types of cancer among women. It is also the second cause of mortality in women. The association between the use of oral contraceptive pills and breast cancer is controversial and a main issue in public health. Some findings have shown that taking these pills does not have a significant effect in increasing the risk of breast cancer, while others have confirmed the carcinogenic effect of these products. These contradictory findings necessitated this meta-analysis, through of all correlated studies in Iran. All published studies were considered from June 2000 until June 2015, using reliable Latin databases like PubMed, Google Scholar, Google search, Scopus, and Science Direct, and Persian database like SID, Irandoc, IranMedex, and Magiran. Finally, 26 papers were selected: 24 studies were case control while two were population based studies. A total of 26 papers with 46,260 participants were assessed since 2001. Overall estimate of OR for the effect of oral contraceptive pills on breast cancer is 1.521 (CI = 1.25-1.85), which shows that the intervention group had more chance (52%) compared to the control group ( P = 0.001). Using these pills increased the risk of breast cancer up to 1.52 times. Because of directly increasing levels of estrogen and the role of estrogen in gaining weight indirectly, oral contraceptive pills can stimulate the occurrence of breast cancer. More studies should be conducted for controlling the period of pill use.

Contraception for adolescents with chronic rheumatic diseases

Directory of Open Access Journals (Sweden)

Benito Lourenço

Full Text Available ABSTRACT Contraception is an important issue and should be a matter of concern in every medical visit of adolescent and young patients with chronic rheumatic diseases. This narrative review discusses contraception methods in adolescents with juvenile systemic lupus erythematosus (JSLE, antiphospholipid syndrome (APS, juvenile idiopathic arthritis (JIA and juvenile dermatomyositis (JDM. Barrier methods are safe and their use should be encouraged for all adolescents with chronic rheumatic diseases. Combined oral contraceptives (COC are strictly prohibited for JSLE and APS patients with positive antiphospholipid antibodies. Reversible long-acting contraception can be encouraged and offered routinely to the JSLE adolescent patient and other rheumatic diseases. Progestin-only pills are safe in the majority of rheumatic diseases, although the main concern related to its use by adolescents is poor adherence due to menstrual irregularity. Depot medroxyprogesterone acetate injections every three months is a highly effective contraception strategy, although its long-term use is associated with decreased bone mineral density. COC or other combined hormonal contraceptive may be options for JIA and JDM patients. Oral levonorgestrel should be considered as an emergency contraception method for all adolescents with chronic rheumatic diseases, including patients with contraindication to COC.

A variety of contraception options are available in addition to traditional combined oral contraceptive pills. Newer long-acting reversible contraceptive (LARC) methods such as intrauterine devices and subcutaneous implants are preferred because they do not depend on patient compliance. They are highly effective and appropriate for most women. Female and male sterilization are other effective but they are irreversible and require counseling to minimize regret. The contraceptive injection, patch, and ring do not require daily administration, but their typical efficacy rates are lower than LARC methods and similar to those for combined oral contraceptive pills.

Despite the availability of effective contraceptive methods, unintended pregnancy continues to be a significant health problem for women throughout the world. The reasons for unplanned pregnancy include failure to use contraception, incorrect use of contraception, unplanned consensual intercourse, and rape. Emergency contraception was once heralded as a means of reducing the rates of unintended pregnancy, elective abortion, and unwanted childbirth. But more than three decades after the first oral form was introduced, the use of emergency contraception remains suboptimal-even in the United States, where it is available to most women of childbearing age without a prescription. Nurses can help narrow this clinical gap in women's health care by increasing awareness of emergency contraception, correcting common misconceptions about its mechanism of action and potential adverse effects, and facilitating patient access.

Oral contraceptive pills are among the most popular contraceptive methods, but the fear of cancer and cardiovascular disease overshadows its continuous use among women. This study aimed to define the association between consumption patterns of combined oral contraceptives among women with breast cancer. This is an analytical case-control study conducted on 175 women with breast cancer, referring to Seyed al Shohada Medical Center and private clinics in Isfahan to be treated and followed up in 2011, as well as 350 healthy women who were identical with the subjects in the study group regarding age and residential location. The data were collected using a researcher-made questionnaire. Content validity and Cronbach's alpha were employed to confirm validity and scientific reliability of the questionnaire, respectively. The data were analyzed by descriptive and analytical statistical methods through SPSS. The findings showed that there was a significant association between history of contraceptive pills' consumption and incidence of breast cancer (P pills' consumption compared to those with no history of that. It was also shown that pills' consumption for 36-72 months increased the risk of breast cancer by 2.18-fold, the age of the first use being less than 20 years increased the risk by 3.28-fold, and time since the last use of less than 25 years increased the risk by 2.63-fold. There was no significant association between duration of use, age of the first and last use, and time since the first and last use in the study and control groups. The results showed that history of pills' consumption is associated with incidence of breast cancer regardless of the consumption pattern. Use of oral contraceptives pills at any age and for any duration can increase the risk of breast cancer.

Emergency contraception includes contraceptive methods used to prevent pregnancy in the first few days after unprotected intercourse, sexual assault, or contraceptive failure. Although the U.S. Food and Drug Administration approved the first dedicated product for emergency contraception in 1998, numerous barriers to access to emergency contraception remain. The purpose of this Committee Opinion is to examine the barriers to the use of oral emergency contraception methods and to highlight the importance of increasing access.

Most contraceptive methods present benefits beyond contraception; however, despite a large body of evidence, many healthcare professionals (HCPs), users and potential users are unaware of those benefits. This review evaluates the evidence for non-contraceptive benefits of hormonal and non-hormonal contraceptive methods. We searched the medical publications in PubMed, POPLINE, CENTRAL, EMBASE and LILACS for relevant articles, on non-contraceptive benefits of the use of hormonal and intrauterine reversible contraceptive methods, which were published in English between 1980 and July 2014. Articles were identified using the following search terms: 'contraceptive methods', 'benefits', 'cancer', 'anaemia', 'heavy menstrual bleeding (HMB)', 'endometrial hyperplasia', 'endometriosis' and 'leiomyoma'. We identified, through the literature search, evidence that some combined oral contraceptives have benefits in controlling HMB and anaemia, reducing the rate of endometrial, ovarian and colorectal cancer and ectopic pregnancy as well as alleviating symptoms of premenstrual dysphoric disorder. Furthermore, the use of the levonorgestrel-releasing intrauterine system also controls HMB and anaemia and endometrial hyperplasia and cancer, reduces rates of endometrial polyps in users of tamoxifen and alleviates pain associated with endometriosis and adenomyosis. Depot medroxyprogesterone acetate controls crises of pain associated with sickle cell disease and endometriosis. Users of the etonogestrel-releasing contraceptive implant have the benefits of a reduction of pain associated with endometriosis, and users of the copper intrauterine device have reduced rates of endometrial and cervical cancer. Despite the high contraceptive effectiveness of many hormonal and intrauterine reversible contraceptive methods, many HCPs, users and potential users are concerned mainly about side effects and safety of both hormonal and non-hormonal contraceptive methods, and there is scarce information

Objective: To assess the coagulation and glycemic status in Pakistani women using contraceptives. Design: The study was conducted prospectively on 70 women and compared with 10 age-matched controls. Place and Duration of Study: The study was conducted at Karachi. Period of study was 18 month. Subjects and Methods: Eighty women aged between 20-45 years selected from low socioeconomic class and poor family background were categorized in control (n=10) and oral and injectable contraceptive users (n = 70). The contraceptives used were tablet Lofemenal, injection Norigest and Norplant implant. Their blood was tested for fibrinogen titer and random blood glucose. Results: There was no appreciable difference either in fibrinogen titer or plasma glucose levels in injectable users as compared to controls, but increased incidence of high fibrinogen titer and borderline blood glucose was observed in oral contraceptive users 25% and 20 % respectively. Conclusion: It was concluded that long-term use of oral contraceptives (> 3 years) might increase the thrombotic tendency and elevate the plasma glucose levels especially in women above 30 years of age.

Extended and continuous use of hormonal contraceptives to reduce menstruation.

Wiegratz, Inka; Kissler, Stefan; Kuhl, Herbert; Kaufmann, Manfred

2006-09-01

During the use of long-cycle regimens of monophasic oral contraceptives, the total number of bleeding and cycle-dependent complaints is considerably lower than during conventional treatment with oral contraceptives. Despite an initially higher rate of irregular bleeding, the majority of women prefer the long-cycle treatment since it may improve quality of life. As this regimen provides an enhanced ovarian suppression, it may prevent pregnancies, especially in noncompliant women or patients who are concomitantly treated with drugs that may impair the efficacy of oral contraceptives. Postponement or suppression of withdrawal bleeding also reduces menses-associated disorders such as menorrhagia and dysmenorrhea, and has beneficial effects in patients with hemorrhagic diathesis, endometriosis, uterine leiomyomas and polycystic ovary syndrome. Long-term studies are necessary to assess the impact of long-term use of extended regimens of oral contraceptives on safety, for example, the risk of cancer and cardiovascular disease, and on fertility after discontinuation of treatment.

Elevated clotting factors have been demonstrated to be a risk factor for venous thromboembolism (VTE). The aim of our study was to investigate the impact of age, sex, body mass index, and oral contraceptives on the clotting factor activities of factors VIII, IX, XI, and XII and their impact on the cutoff definition and risk of VTE associated with elevated clotting factors. Factor VIII, IX, XI, and XII activities were measured in 499 blood donors and 286 patients with VTE. Age and body mass index predicted significantly and independently the clotting factor activities of factors VIII, IX, and XI, whereas use of oral contraceptives predicted factor IX, XI, and XII levels. Percentiles of clotting factor activities, which are often used for the cutoff definition of elevated clotting factors, varied due to the effect of age, body mass index, and oral contraceptives. The adjusted odds ratios for VTE were 10.3 [95% confidence interval (CI) 5.1-20.7], 6.1 (95% CI 3.1-12.0), and 3.3 (95% CI 1.9-5.8) for elevated factors VIII, IX, and XI, respectively. Furthermore, our study demonstrates for the first time that elevated factor XII is associated with an increased risk of VTE (adjusted odds ratio 2.9, 95% CI 1.6-5.3).

Each of the four inactive tablets contains 75 mg ferrous fumarate, which has no therapeutic benefit. The tablet can be taken with food but not water as this affects the absorption of EE. The Pearl index based on intention to treat women aged 18–35 years has been reported at 2.01 (confidence interval [CI] 1.21, 3.14 and for the whole population 1.65 (CI 1.01, 2.55. The effect of a body mass index of >35 was not studied. Regular withdrawal bleeding occurred for 78.6% of women in Cycle 1, but by Cycle 13 almost half the women failed to have a withdrawal bleed. This new formulation provides an intermediate dose of an EE/NE combination that will be useful for women experiencing breakthrough bleeding on the lower-dose EE/NE pill. The convenience of a low-dose pill, which can be chewed without the need for water, will be useful to enable women who have forgotten a pill to take one whenever they remember, provided they carry it with them. The advantage of a 24/4 regimen is better suppression of follicular development in the pill-free interval and may be beneficial for women who experience menstrual cycle-related problems, such as heavy bleeding or dysmenorrhea.Keywords: combined oral contraceptive, low dose, ethinyl estradiol, norethindrone

Controversies in contraception for women with epilepsy

Full Text Available Contraception is an important choice that offers autonomy to women with regard to prevention of unintended pregnancies. There is wide variation in the contraceptive practices between continents, countries, and societies. The medical eligibility for contraception for sexually active women with epilepsy (WWE is determined by the type of anti-epileptic drugs (AEDs that they use. Enzyme inducing AEDs such as phenobarbitone, phenytoin, carbamazepine, and oxcarbazepine increase the metabolism of orally administered estrogen (and progesterone to a lesser extent. Estrogen can increase the metabolism of certain AEDs, such as lamotrigine, leading to cyclical variation in its blood level with resultant adverse effect profile or seizure dyscontrol. AEDs and sex hormones can increase the risk of osteoporosis and fracture in WWE. The potential interactions between AEDs and hormonal contraception need to be discussed with all women in reproductive age-group. The alternate options of oral contraception such as intrauterine copper device, intrauterine levonorgestrel release system, and supplementary protection with barriers need to be presented to them. World Health Organization has recommended to avoid combination contraceptive pills containing estrogen and progesteron in women who desire contraception and in breastfeeding mothers. Care providers need to consider the option of non-enzyme-inducing AEDs while initiating long-term treatment in adolescent and young WWE.

Full Text Available ABSTRACT Objective: To identify scientific evidence regarding the influence of hormonal contraceptive use and the occurrence of stroke. Method: Integrative review of the literature, through database search using the descriptors "contraceptive agents", "contraceptive devices", "contraceptives, Oral" and "Stroke". Original studies in Portuguese, Spanish and English, published in full and available online were included. Studies that did not answer our guiding questions and duplicated studies were excluded. Results: Women using combined oral contraceptives have higher risk of stroke, even with a lower hormonal dosage and different types of progestogen, regardless of the duration of use. The use of contraceptives associated with smoking, hypertension, migraine, hypercholesterolemia, obesity and sedentary lifestyle increases the chance of stroke. Contraceptive patch and vaginal ring are associated to increased risk. Conclusion: Use of combined hormonal contraceptives, except for the injectable and the transdermal ones, increases the chance of occurrence of the event. Progestogen-only contraceptives were considered safe.

The interaction between legalization of abortion and contraception in Denmark.

Science.gov (United States)

Matthiessen, P C

1979-01-01

Trends in fertility, abortion, and contraceptive practice in Denmark were analyzed, using previously compiled official statistics; the conclusion was drawn that easy access to abortion may contribute toward a decline in contraceptive practice depending on the level of contraceptive practice in the population and on the degree of confidence the population has in available contraceptive methods. In October 1973 Denmark passed a law permitting women to obtain free abortion on demand. The number of legal abortions increased from 16,500 in 1973 to 28,000 in 1975. This marked increase was not attributable to a decline in illegal abortion since that annual number had declined from 5,000 to 1,000 prior to the passage of the 1973 abortion on demand law. The increase in abortion observed from 1973-1975 was accompanied by a marked decrease in the number of oral contraceptive cycles sold. Annual sales decreased from 3.9 million cycles to 2.6 million. It was difficult to access the factors responsible for this decline. Although IUD insertions increased during this period, the increase could not adequately compensate for the reduction in oral contraceptive sales. The decline in oral contraceptive sales occurred at about the time the negative side effects associated with the pill received widespread news coverage. Some of the decline in pill usage was probably due to fear of side effects, but abortion availability also encouraged women to be more lax about taking the pill and encouraged them to rely on less effective methods of contraception. Tables provide data for Denmark in reference to: 1) number of legal abortions and the abortion rates for 1940-1977; 2) distribution of abortions by season, 1972-1977; 3) abortion rates by maternal age, 1971-1977; 4) oral contraceptive and IUD sales for 1977-1978; and 5) number of births and estimated number of abortions and conceptions, 1960-1975.

Extended regimen combined oral contraception: A review of evolving concepts and acceptance by women and clinicians.

Nappi, Rossella E; Kaunitz, Andrew M; Bitzer, Johannes

2016-01-01

The clinical utility of extended regimen combined oral contraceptives (COCs) is increasingly being recognised. Our objective was to understand the attitudes of women and clinicians about the use of these regimens. We present the rationale for extended regimen COCs from a historical perspective, and trace their evolution and growing popularity in light of their clinical benefits. We conclude by offering potential strategies for counselling women about extended regimen COC options. We conducted a MEDLINE search to identify and summarise studies of extended regimen COCs, focusing on attitudes of women and clinicians regarding efficacy, safety/tolerability and fewer scheduled bleeding episodes and other potential benefits. The body of contemporary literature on extended regimen COCs suggests that their contraceptive efficacy is comparable to that of conventional 28-day (i.e., 21/7) regimens. For women seeking contraception that allows infrequent scheduled bleeding episodes, particularly those who suffer from hormone withdrawal symptoms and cyclical symptoms (e.g., headache, mood changes, dysmenorrhoea, heavy menstrual bleeding), extended regimen COCs are an effective and safe option. Although satisfaction with extended regimen COCs in clinical trials is high, misperceptions about continuous hormone use may still limit the widespread acceptance of this approach. Despite the widespread acceptance among clinicians of extended regimen COCs as an effective and safe contraceptive option, these regimens are underused, likely due to a lack of awareness about their availability and utility among women. Improved patient education and counselling regarding the safety and benefits of extended regimen COCs may help women make more informed contraceptive choices.

Steady progress in contraception research has been achieved over the past 50 years. Hormonal and nonhormonal modern contraceptives have improved women's lives by reducing different health conditions that contributed to considerable morbidity. However, the contraceptives available today are not suitable to all users, and the need to expand contraceptive choices still exists. Novel products such as new implants, contraceptive vaginal rings, transdermal patches and newer combinations of oral contraceptives have recently been introduced in family planning programs, and hormonal contraception is widely used for spacing and limiting births. Concerns over the adverse effects of hormonal contraceptives have led to research and development of new combinations with improved metabolic profile. Recent developments include use of natural compounds such as estradiol and estradiol valerate with the hope to decrease thrombotic risk, in combination with newer progestins derived from the progesterone structure or from spirolactone, in order to avoid the androgenic effects. Progesterone antagonists and progesterone receptor modulators are highly effective in blocking ovulation and preventing follicular rupture and are undergoing investigations in the form of oral pills and in semi-long-acting delivery systems. Future developments also include the combination of a contraceptive with an antiretroviral agent for dual contraception and protection against sexually transmitted diseases, to be used before intercourse or on demand, as well as for continuous use in dual-protection rings. Although clinical trials of male contraception have reflected promising results, limited involvement of industry in that area of research has decreased the likelihood of having a male method available in the current decade. Development of nonhormonal methods is still at an early stage of research, with the identification of specific targets within the reproductive system in ovaries and testes, as well as

Tofacitinib is an oral Janus kinase inhibitor. Tofacitinib metabolism is primarily mediated by cytochrome P450 3A4. This phase 1 randomized, open-label, 2-way crossover study (NCT01137708) evaluated the effect of tofacitinib 30 mg twice daily on the single-dose pharmacokinetics of combination oral contraceptives ethinylestradiol (EE) and levonorgestrel (LN). EE and LN were administered as a single Microgynon 30® tablet (30 μg EE and 150 μg LN) to 19 healthy women. In the presence of tofacitinib, the area under the curve from time zero to infinity (AUC∞ ) increased by 6.6% and 0.9% for EE and LN, respectively. Maximal plasma concentrations decreased by 10.4% for EE and increased by 12.2% for LN when coadministered with tofacitinib. The 90% confidence intervals for the adjusted geometric mean ratios for AUC∞ fell within the 80%-125% region for both EE and LN. Mean half-life was similar in the presence and absence of tofacitinib: 13.8 and 13.3 hours, respectively, for EE; 25.9 and 25.4 hours, respectively, for LN. Tofacitinib had no clinically relevant net inhibitory or inductive effect on the pharmacokinetics of EE and LN. Therefore, there is no evidence to suggest dose adjustments of oral contraceptive drugs containing EE or LN when coadministered with tofacitinib. © 2016, The American College of Clinical Pharmacology.

InaSAFE applications in disaster preparedness

Pranantyo, Ignatius Ryan; Fadmastuti, Mahardika; Chandra, Fredy

2015-04-01

Disaster preparedness activities aim to reduce the impact of disasters by being better prepared to respond when a disaster occurs. In order to better anticipate requirements during a disaster, contingency planning activities can be undertaken prior to a disaster based on a realistic disaster scenario. InaSAFE is a tool that can inform this process. InaSAFE is a free and open source software that estimates the impact to people and infrastructure from potential hazard scenarios. By using InaSAFE, disaster managers can develop scenarios of disaster impacts (people and infrastructures affected) to inform their contingency plan and emergency response operation plan. While InaSAFE provides the software framework exposure data and hazard data are needed as inputs to run this software. Then InaSAFE can be used to forecast the impact of the hazard scenario to the exposure data. InaSAFE outputs include estimates of the number of people, buildings and roads are affected, list of minimum needs (rice and clean water), and response checklist. InaSAFE is developed by Indonesia's National Disaster Management Agency (BNPB) and the Australian Government, through the Australia-Indonesia Facility for Disaster Reduction (AIFDR), in partnership with the World Bank - Global Facility for Disaster Reduction and Recovery (GFDRR). This software has been used in many parts of Indonesia, including Padang, Maumere, Jakarta, and Slamet Mountain for emergency response and contingency planning.

Full Text Available Coronary angioplasty is recognized nowadays as the first-choice therapeutic strategy for acute coronary syndrome with ST-segment elevation. Atherosclerotic disease is still the main cause ofthis sickness; however, other disturbances, such is dilated coronariopathy, may favor this coronary event. Although some authors raise that atherosclerosis is the main cause of coronary dilation, it is uncommon that this lipid disorder promotes consequences early in life. We present the case of a 33-year-old female (oral contraceptive user - etinor who had not any apparent coronary risk factor but suffered from inferior acute myocardial infarction. The thrombolysis failed, and fortunately we could perform the angioplasty. Intracoronary thrombosis with distal embolism occurred, that waswhy we administered streptokinase. Possible mechanisms that involve oral contraceptives and dilated coronariopathy are discussed, and angiographic images are shown.

Unintended pregnancy rates in the United States remain high among adolescents. Emergency contraception (EC) provides the only option for pregnancy prevention after unprotected sex. To better define the population of adolescents who request and use EC pills, we performed a post hoc analysis of an over-the-counter simulation study of EC pills. Teen reproductive health clinics in 5 cities. Adolescents between the ages of 13 and 17 years who requested EC. Single-tablet levonorgestrel 1.5 mg. We calculated the correlations between age and baseline sexual and contraceptive behaviors. χ 2 Tests were used to compare behaviors of first-time and repeat EC users. Overall, the most commonly reported contraceptive methods ever used were condoms, oral contraceptives, none, and withdrawal; the most common method ever used in each age group was no method for 13- to 14-year-olds and condom for 15-, 16-, and 17-year-olds. The percentage of participants who had never used contraception before requesting EC decreased with age (53% [20/28] of 13- to 14-year-olds vs 15% [10/65] of 17-year-olds). First-time EC users were more likely to report no previous contraceptive use compared with repeat EC users (42% [88/208] vs 10% [13/135]; P contraceptive method (ie, "unprotected sex"). Adolescents who requested EC most commonly reported ever-use of contraceptive methods that rely on user adherence or no method at all, with younger adolescents more likely than older adolescents to have used no previous method. The provision of EC presents an opportunity to provide education and access to highly effective, long-term contraceptive methods.

Zorbas, Konstantinos A; Economopoulos, Konstantinos P; Vlahos, Nikos F

2015-07-01

Recurrence of endometriosis after conservative surgery has been observed in 40-50 % of patients within the first 5 years. A variety of regimens such as combined oral contraceptives, GnRH agonists, danazol, and progestins have been used postoperatively to reduce recurrence rates. Oral contraceptives (oCP) have been used either in a cyclic or in a continuous (no pill-free interval) fashion. The purpose of this article was to summarize the existing evidence on the efficacy and patient compliance for the use of oCP in a continuous versus cyclic fashion following conservative surgery for endometriosis. A systematic search of Medline identified four eligible studies. Studies were considered eligible, if they have evaluated oCP therapy, either in a cyclic or continuous regimen, after conservative surgery for endometriosis. Specifically, studies (1) reporting on women with endometriosis who were treated postoperatively with both continuous oCP and cyclic oCP, (2) written in English, (3) with minimum 6 months duration of medical treatment, and (4) with minimum 12 months duration of follow-up were considered eligible for our systematic review. Outcome measures of these eligible studies were tabulated and then analyzed cumulatively. A purely descriptive approach was adopted concerning all variables. Postoperative use of continuous oCP was associated with a reduction in the recurrence rate of dysmenorrhea, delay in the presentation of dysmenorrhea, reduction in nonspecific pelvic pain, and reduction in the recurrence rate for endometrioma. Use of oCP in a continuous fashion following conservative surgery for endometriosis is more beneficial to cyclic use.

Dermish, Amna I; Turok, David K

2013-07-01

Worldwide, 40% of all pregnancies are unintended. Widespread, over-the-counter availability of oral emergency contraception (EC) has not reduced unintended pregnancy rates. The EC visit presents an opportunity to initiate a highly effective method of contraception in a population at high risk of unintended pregnancy who are actively seeking to avoid pregnancy. The copper intrauterine device (IUD), the most effective method of EC, continues to provide contraception as effective as sterilization for up to 12 years, and it should be offered as the first-line method of EC wherever possible. Increased demand for and supply of the copper IUD for EC may have an important role in reducing rates of unintended pregnancy. The EC visit should include access to the copper IUD as optimal care but should ideally include access to all highly effective methods of contraception.

the expanded program were more likely to choose sterilization (OR 4.26; 95% CI 2.46 to 7.37) or use a modern contraceptive method (OR 2.35; 95% CI 1.82 to 3.03), i.e., sterilization, pills, injectable, intrauterine device or barrier method. For the other study, the groups received educational interventions with differing format and intensity. Both groups reportedly had increases in contraceptive use, but they did not differ significantly by six months in consistent use of an effective contraceptive, i.e., sterilization, IUD, injectable, implant, and consistent use of oral contraceptives, diaphragm, or male condoms.Five trials provided one session and focused on testing educational material or media. In one study, knowledge gain favored a slide-and-sound presentation versus a physician's oral presentation (MD -19.00; 95% CI -27.52 to -10.48). In another trial, a table with contraceptive effectiveness categories led to more correct answers than a table based on pregnancy numbers [ORs were 2.42 (95% CI 1.43 to 4.12) and 2.19 (95% CI 1.21 to 3.97)] or a table with effectiveness categories and pregnancy numbers [ORs were 2.58 (95% CI 1.5 to 4.42) and 2.03 (95% CI 1.13 to 3.64)]. Still another trial provided structured counseling with a flipchart on contraceptive methods. The intervention and usual-care groups did not differ significantly in choice of contraceptive method (by effectiveness category) or in continuation of the chosen method at three months. Lastly, a study with couples used videos to communicate contraceptive information (control, motivational, contraceptive methods, and both motivational and methods videos). The analyses showed no significant difference between the groups in the types of contraceptives chosen. These trials varied greatly in the types of participants and interventions to communicate contraceptive effectiveness. Therefore, we cannot say overall what would help consumers choose an appropriate contraceptive method. For presenting pregnancy risk

Oral contraceptive use in women changes preferences for male facial masculinity and is associated with partner facial masculinity.

2013-09-01

Millions of women use hormonal contraception and it has been suggested that such use may alter mate preferences. To examine the impact of oral contraceptive (pill) use on preferences, we tested for within-subject changes in preferences for masculine faces in women initiating pill use. Between two sessions, initiation of pill use significantly decreased women's preferences for male facial masculinity but did not influence preferences for same-sex faces. To test whether altered preference during pill use influences actual partner choice, we examined facial characteristics in 170 age-matched male partners of women who reported having either been using or not using the pill when the partnership was formed. Both facial measurements and perceptual judgements demonstrated that partners of women who used the pill during mate choice have less masculine faces than partners of women who did not use hormonal contraception at this time. Our data (A) provide the first experimental evidence that initiation of pill use in women causes changes in facial preferences and (B) documents downstream effects of these changes on real-life partner selection. Given that hormonal contraceptive use is widespread, effects of pill use on the processes of partner formation have important implications for relationship stability and may have other biologically relevant consequences.

While combined oral contraceptives are a popular choice in developed Western countries, they are used by only 1% of women who are married or in a relationship in the People's Republic of China. The purpose of this review is to describe the efficacy and safety of the combined oral contraceptive containing ethinylestradiol (EE) 20 µg/drospirenone 3 mg taken in a 24/4 regimen (YAZ ® ; Bayer HealthCare Pharmaceuticals, Berlin, Germany) by Chinese women and to compare these results with those in women assessed in the international studies. Studies of EE 20 µg/drospirenone 3 mg in three different indications (contraception, acne, and premenstrual dysphoric disorder [PMDD]) have been conducted in Chinese women. The results of these three studies indicate that the EE 20 µg/drospirenone 3 mg combined oral contraceptive is a good long-term contraceptive option in Chinese women, providing 99% contraceptive protection over the observed 1-year treatment period, and additionally had a favorable effect on moderate acne vulgaris and relieved the symptoms of PMDD. The contraceptive efficacy, improvement in acne, and relief from PMDD symptoms observed in these studies did not differ from the effects observed in other international studies of EE 20 µg/drospirenone 3 mg, indicating that EE 20 µg/drospirenone 3 mg is as effective in Chinese women as in other ethnicities. Further, EE 20 µg/drospirenone 3 mg demonstrated a similar safety and tolerability profile in women enrolled in the Chinese and international trials, with no unexpected adverse events reported in any of the three Chinese trials. Overall, the efficacy, tolerability, and degree of non-contraceptive benefits with EE 20 µg/drospirenone 3 mg appear similar in Chinese women when compared with those reported in larger studies done at other international centers.

Oral candidiasis (OC) is a common fungal disease encountered in dermatology, most commonly caused by an overgrowth of Candida albicans in the mouth. Although thrush is a well-recognized presentation of OC, it behooves clinicians to be aware of the many other presentations of this disease and how to accurately diagnose and manage these cases. The clinical presentations of OC can be broadly classified as white or erythematous candidiasis, with various subtypes in each category. The treatments include appropriate oral hygiene, topical agents, and systemic medications. This review focuses on the various clinical presentations of OC and treatment options.

The mechanisms linking ovarian hormones to negative affect are poorly characterized, but important clues may come from the examination of the brain's intrinsic organization. Here, we studied the effects of both the menstrual cycle and oral contraceptives (OCs) on amygdala and salience network resting-state functional connectivity using a double-blind, randomized, and placebo-controlled design. Hormone levels, depressive symptoms, and resting-state functional connectivity were measured in 35 healthy women (24.9±4.2 years) who had previously experienced OC-related negative affect. All participants were examined in the follicular phase of a baseline cycle and in the third week of the subsequent cycle during treatment with either a combined OC (30 μg ethinyl estradiol/0.15 mg levonorgestrel) or placebo. The latter time point targeted the midluteal phase in placebo users and steady-state ethinyl estradiol and levonorgestrel concentrations in OC users. Amygdala and salience network connectivity generally increased with both higher endogenous and synthetic hormone levels, although amygdala-parietal cortical connectivity decreased in OC users. When in the luteal phase, the naturally cycling placebo users demonstrated higher connectivity in both networks compared with the women receiving OCs. Our results support a causal link between the exogenous administration of synthetic hormones and amygdala and salience network connectivity. Furthermore, they suggest a similar, potentially stronger, association between the natural hormonal variations across the menstrual cycle and intrinsic network connectivity.

Emerging Options for Emergency Contraception

Emergency post-coital contraception (EC) is an effective method of preventing pregnancy when used appropriately. EC has been available since the 1970s, and its availability and use have become widespread. Options for EC are broad and include the copper intrauterine device (IUD) and emergency contraceptive pills such as levonorgestrel, ulipristal acetate, combined oral contraceptive pills (Yuzpe method), and less commonly, mifepristone. Some options are available over-the-counter, while others require provider prescription or placement. There are no absolute contraindications to the use of emergency contraceptive pills, with the exception of ulipristal acetate and mifepristone. This article reviews the mechanisms of action, efficacy, safety, side effects, clinical considerations, and patient preferences with respect to EC usage. The decision of which regimen to use is influenced by local availability, cost, and patient preference. PMID:24453516

Electrical characterization of InAs thin films

It is known that parallel conduction as a result of surface and /or interface charge accumulation significantly shields the bulk electrical properties of InAs thin films when characterized using Hall measurements. This parallel conduction in InAs can be modeled by using the two-layer model of Nedoluha and Koch [Zeitschrift fuer Physik 132, 608 (1952)]; where an InAs epilayer is treated as consisting of two conductors connected in parallel viz. a bulk and a surface layer. Here, this two-layer model is used to simulate Hall coefficient and conductivity data of InAs thin films ranging from strongly n-doped (n=10{sup 18} cm{sup -3}) to strongly p-doped (p{proportional_to}10{sup 19} cm{sup -3}) material. Conventional Hall approximations, i.e. those that assume uniform conduction from a single band, are then used to predict the apparent carrier concentration and mobility that will be determined from conventional Hall measurements, with the aim of illustrating the error of such a simplified analysis of InAs Hall data. Results show that, in addition to ignoring parallel conduction, the approximations of conventional Hall data analysis have a further inadequacy for p-type InAs, in that the high electron to hole mobility ratio in InAs is not taken into account.

The risk-benefit profile of any pharmacologic agent must be evaluated against risks connected with the events to be avoided. This is especially true in the case of hormonal contraception, not intended to combat a disease. Over the six decades during which their use has progressively expanded, the risk-benefit profile of combined oral contraceptives (COC) has substantially changed, with new combinations, dosages and mode of administration appearing on the market. Area covered: In a series of articles, recent information on the complex issue of COC risks and benefits will be reviewed in the hope of providing an updated picture. The present article reviews metabolic changes occurring during use of modern combinations of estrogens (ethinyl estradiol, estradiol, estradiol valerate and estetrol) and new progestins (desogestrel, gestodene, dienogest, drospirenone, nomegestrol acetate), often compared to classic compounds, such as levonorgestrel. Three categories of metabolic effects in healthy women are detailed: on carbohydrates, lipid and bone mineral content. Expert commentary: Overall, the picture is reassuring: the new generations of progestins are basically devoid of androgenic, estrogenic or glucocorticoid related side-effects. This should result in an improved safety profile, although past history teaches us that that large comparative and surveillance studies are required before firm conclusions can be drawn. At any rate, available evidence indicates that metabolic effects of third and fourth generation progestins, especially when they are combined with natural estrogens, are minimal and, if used in healthy women, should not cause concern.

Oral contraceptive pills: A risk factor for retinal vascular occlusion in in-vitro fertilization patients

Full Text Available Retinal vascular occlusion is the most common cause of retinopathy leading to severe visual loss in all age groups. Central retinal vein occlusion (CRVO is usually seen in older age group and is often associated with systemic vascular diseases. Although the exact cause and effect relationship has not been proven, central retinal vein occlusion has been associated with various systemic pathological conditions, hence a direct review of systems toward the various systemic and local factors predisposing the central retinal vein occlusion is advocated. We describe the development of central retinal venous occlusion with associated cystoid macular edema (CME in two healthy infertile women who were recruited for in vitro fertilization cycle for infertility. Predisposing risk factors associated with central retinal vein occlusion are obesity, sedentary life style, smoking, and some systemic diseases such as hyperlipidemia, hypertension, associated autoimmune disorders e.g., antiphospholipid antibody syndrome, lupus, diabetes mellitus, cardiovascular disorders, bleeding or clotting disorders, vasculitis, closed-head trauma, alcohol consumption, primary open-angle glaucoma or angle-closure glaucoma.In our patients, they were ruled out afterdoing allpertaining investigations. The cases were managed with further avoidance of oral contraceptives and intra-vitreal injections of Bevacizumab (Avastin, an anti-vascular endothelial growth factor (anti-VEGF drug and Triamcinolone acetonide (a long acting synthetic steroid. Hence, even if no systemic diseases are detected. Physical examinations are recommended periodically for young women on oral contraceptive pills.

Oral contraceptives in polycystic ovary syndrome: risk-benefit assessment.

Science.gov (United States)

Yildiz, Bulent O

2008-01-01

Combined oral contraceptive pills (OCPs) have been a key component of the chronic treatment of polycystic ovary syndrome (PCOS) by improving androgen excess and regulating menstrual cycles. Earlier epidemiologic studies with second- and third-generation OCPs in the general population have raised important questions regarding long-term cardiometabolic effects of these agents. In PCOS, there are only a few short-term studies with contradictory results evaluating potential adverse effects of OCPs on cardiovascular risk factors and glucose homeostasis. These studies included a small number of participants and did not take into account several confounding factors that might influence the outcome. Nevertheless, limited available data support the benefits of long-term OCP use in PCOS. By contrast, solid evidence for cardiometabolic adverse outcome with the use of these agents, especially with newer OCPs containing antiandrogenic progestins, is lacking. More studies are needed to resolve controversies regarding the safety of long-term OCP use in PCOS. Meanwhile, assessment of each PCOS patient's personal cardiometabolic risk profile should be an essential component of the evaluation before prescribing OCPs and also during follow-up.

"I love my ECPs": challenges to bridging emergency contraceptive users to more effective contraceptive methods in Ghana.

L'Engle, Kelly Ladin; Hinson, Laura; Chin-Quee, Dawn

2011-07-01

Emergency contraceptive pills (ECPs) are becoming more popular, yet little is known about the contraceptive preferences of women who take ECPs. Women purchasing ECPs were recruited from pharmacies in Accra, Ghana. A total of 24 semi-structured, qualitative interviews were conducted in May 2008. Nearly all participants preferred ECPs to other contraceptive methods. Although fear of side effects from oral contraceptive pills (OCPs), intrauterine devices and injectables were deterrents to use of those methods, side effects from ECPs were acceptable to this small and highly self-selected group of ECP users. Participants had little knowledge about how other contraceptive methods work and expressed a strong distrust and dislike of condoms. Study participants loved their ECPs, despite minor discomforts like bleeding, and most had no concerns about repeated use, though these findings may not apply to women outside Accra or women who obtain ECPs from non-pharmacy settings. Future interventions should work to dispel myths about OCPs, condoms and other modern methods, and focus on basic contraception education.

New approaches to male non-hormonal contraception.

Science.gov (United States)

Nya-Ngatchou, Jean-Jacques; Amory, John K

2013-03-01

A non-hormonal male contraceptive is a contraceptive that does not involve the administration of hormones or hormone blockers. This review will focus on the use of lonidamine derivatives and inhibitors of retinoic acid biosynthesis and function as approaches to male non-hormonal contraception. Two current lonidamine derivatives, adjudin and H2-gamendazole, are in development as male contraceptives. These potent anti-spermatogenic compounds impair the integrity of the apical ectoplasmic specialization, resulting in premature spermiation and infertility. Another approach to male contraceptive development is the inhibition of retinoic acid in the testes, as retinoic acid signaling is necessary for spermatogenesis. The administration of the retinoic acid receptor antagonist BMS-189453 reversibly inhibits spermatogenesis in mice. Similarly, oral dosing of WIN 18,446, which inhibits testicular retinoic acid biosynthesis, effectively contracepts rabbits. Hopefully, one of these approaches to non-hormonal male contraception will prove to be safe and effective in future clinical trials. Copyright © 2013 Elsevier Inc. All rights reserved.

Objective: To investigate antioxidant status of women on four different methods of contraception. Methodology: Sixty non-pregnant women aged 16-45 years on oral contraceptive pills, injectables, Norplant and intra-uterine contraceptive devices (IUD) attending the Family Planning Clinics of the University College Hospital (UCH) and Adeoyo Maternity Hospital, Ibadan were recruited for the study. Fifty-eight apparently healthy women aged 16-45 years who were not on any contraceptive served as a control group. The body mass index (BMI) of all participants (subjects and controls) was determined following standard protocol. Serum levels of ascorbic acid, tocopherol, malondialdehyde, bilirubin, creatinine, uric acid, total protein and albumin were determined using standard spectrophotometric methods. Progesterone was estimated by the chemilumiscence method while selenium was determined by atomic absorption spectrophotometry (AAS). Results: The BMI was significant in women on oral contraceptive pills (OCP) when compared to the control group (P 0.05) in intra-uterine device (IUD), injectables and Norplant users. The mean serum ascorbic acid (P 0.05) in users of other contraceptive methods. Serum levels of malondialdehyde was significantly elevated in women on OCP (P 0.05) in users of other contraceptive methods. There was no significant association between progesterone and antioxidants in women on OCP, IUD, injectables and Norplant. Conclusion: Oral contraceptive pills showed a significant decreasing effect on the antioxidant status of its users while IUD, injectables and Norplant did not indicate any significant effect. Routine monitoring of the antioxidant status of women on different methods of contraceptive particularly those on OCP is recommended. (author)

Thrombophilia is associated with increased risks of venous thrombosis in women taking oral contraceptive preparations. Universal thrombophilia screening in women prior to prescribing oral contraceptive preparations is not supported by current evidence. The case is presented of a 23 year-old women with a personal history of interruption and on the same day started with oral contraceptive (0.03 microg ethynil estradiol - 0.075 microg gestodene), which due on a 18 pill/day to acute headache, increasing vomiting and speaking defects. Physical/neurologic/gynecologic examinations observed a normal status. The MRI and CT revealed thrombosis of the left internal jugular vein and brain ischemia with cerebral infarction and ischemic stroke. The acute therapy of thrombotic findings was accompanied with many tests. The thrombophilia PCR-Real time - test finds heterozygous carrier of the Factor V (Leiden). This case shows the need of large prospective studies that should be undertaken to refine the risks and establish the associations of thrombophilias with venous thrombosis among contraceptive users. The key to a prompt diagnosis is to know the risk factors. The relative value of a thrombophilia screening programme before contraceptive using needs to be established.

There are currently 6 million immigrants living in Spain. Half of them are women, the majority of whom are of childbearing age. These women, who suffer high rates of induced abortion, form a special group who require a special approach to their reproductive health. In order to study the use of contraceptive methods in this population, a review was made of 1100 clinical histories from our Sexual Health and Reproduction Clinic. Latin American women were the most prevalent group who came to seek information about contraception, followed by Eastern Europeans and Moroccans. Fewer Asian and Sub-Saharan women sought these services. The contraceptives most frequently used were the intrauterine device (used mostly by Latin American and Eastern European women), and combined oral contraception, most used by Moroccan women. It is important to advise the immigrant women about contraceptive methods, taking into account their preferences, in order to improve adherence to the method.

Contraceptives: choice for the millions?

Dhall, A

India adds each year the population of Sub-Saharan Africa to the earth. User based factors determining the type of contraceptive that is used most often in a country are sociocultural practices including religion, literacy, women's status and their role in decision making, men's status, misconceptions, and convenience of use. Service related factors include knowledge and skill of the provider, attitude of the provider, accessibility of family planning services, cost of the contraceptives, and quality of services. The government, nongovernmental organizations, and the pharmaceutical firms tend to be the contraceptive researchers and suppliers. The mass media are used to disseminate information on contraceptives. They often relay sensational reports about a contraceptive method that results in its reduced use. Temporary or spacing family planning methods include natural family planning methods, condoms, IUDs, oral contraceptives, implants, and injectables, spermicides and vaginal barriers. The natural family planning methods are sexual abstinence, especially in the postpartum period; rhythm or calendar method; and coitus interruptus. The most cost-effective method is also the most popular method--sexual sterilization. Even though female sterilization is more difficult to perform than vasectomy, it is more common than vasectomy. Contraception should become a people's movement rather than be forced upon the people. People should insist on good quality, affordable contraceptive services as their basic right.

Emergency contraception - potential for women's health.

Emergency contraception (EC) is a safe and effective method which is used to prevent unwanted pregnancy after unprotected sexual intercourse. Many of the unwanted pregnancies end in unsafe abortions. The search for an ideal contraceptive, which does not interfere with spontaneity or pleasure of the sexual act, yet effectively controls the fertility, is still continuing. Numerous contraceptive techniques are available, yet contraceptive coverage continues to be poor in India. Thus, even when not planning for a pregnancy, exposure to unprotected sex takes place often, necessitating the use of emergency contraception. This need may also arise due to failure of contraceptive method being used (condom rupture, diaphragm slippage, forgotten oral pills) or following sexual assault. Emergency contraception is an intervention that can prevent a large number of unwanted pregnancies resulting from failure of regular contraception or unplanned sexual activity, which in turn helps in reducing the maternal mortality and morbidity due to unsafe abortions. However, a concern has been expressed regarding repeated and indiscriminate usage of e-pill, currently the rational use of emergency contraception is being promoted as it is expected to make a significant dent in reducing the number of unwanted pregnancies and unsafe abortions. In fact, since the introduction of emergency contraception, the contribution of unsafe abortion towards maternal mortality has declined from 13 to 8 per cent.

Full Text Available Maintenance of reproductive health of women with excessive weight is the actual problem of nowadays and is an important direction of modern medicine. Aim. To analyze the efficiency and acceptability of oral, іntravaginal and transdermal hormonal contraceptives among women with excessive body mass. Methods and results. The tolerability and ease of use of different types of hormonal contraception have been studied in 72 women with excessive body mass to determine the reliability and acceptability of modern hormonal contraceptives. It has been investigated that the effectiveness of hormonal contraceptives according to our data is 100%, none patient was registered with an unwanted pregnancy. The total subjective evaluation of all hormonal contraceptives use were positive: 78.6% of women with excessive body mass who used oral contraceptives, were satisfied with the chosen contraceptive method, 81,8% – were satisfied with intravaginal method, 59,1% – transdermal contraceptive. Conclusions. It has been found that intravaginal contraceptive is most suitable as the drug of first choice for women with overweight compared with oral and transdermal hormonal methods of contraception. This suggests that women with excessive body mass can successfully use modern methods of hormonal contraception. But it is necessary to carry out clinical supervision, during which further clarification on the use of hormonal contraception in women with excessive body mass is possible.

Full Text Available OBJECTIVES: to identify the knowledge of users of combined oral contraceptive about correct use, side effects and complications; to verify the correlation between knowledge about the method with age, education, family income and time of use. METHOD: cross-sectional study performed in Fortaleza, Ceará, Brazil, from March to July 2010, with 294 women. Data were collected through interviews. RESULTS: 75% had substantial knowledge about the proper use and side effects and no knowledge about complications. The higher the educational level and family income, the higher the women's knowledge about the correct use of the method. Positive correlation suggests that women who used the method for longer knew more about its side effects. CONCLUSION: there are knowledge gaps about the method, which are influenced by socioeconomic variables and use time.

Little is known about psychosocial correlates of different contraceptive methods in adolescence. Cross-sectional analyses of 209 postmenarcheal girls [mean age (years)+/-SD=15.68+/-1.74], primarily Caucasian (62.8%) or African American (32.8%). Competence (activities and social) and rule-breaking behavior were assessed by the Youth Self Report (YSR; adolescent) and the Child Behavior Checklist (CBCL; parent). Three contraceptive-use groups were created: no hormonal contraceptive (n=142), combined oral contraceptives or the transdermal patch (COCs/patch, n=41), and depot medroxyprogesterone acetate (DMPA, n=20). There was a significant effect of contraceptive-use group on competence (p=.003). The DMPA group had lower competence (CBCL activities and social; YSR social) than the no-hormonal-contraceptive and COCs/patch groups. The COCs/patch group scored lower than the no-hormonal-contraceptive group on YSR activities competence, but was not different from the DMPA group. Lastly, there was an effect of contraceptive-use group on CBCL (but not YSR) rule-breaking behavior (p=.029) with the DMPA group having higher rule-breaking behavior than the other groups. Type of contraceptive method was associated with parent and adolescent's perceived competence. For rule-breaking behavior, parental perception may be more relevant to contraceptive use.

Full Text Available Luis Bahamondes, M Valeria Bahamondes Human Reproduction Unit, Department of Obstetrics and Gynaecology, Faculty of Medical Sciences, University of Campinas and National Institute of Hormones and Women's Health, Campinas, SP, Brazil Background: The first hormonal contraceptive was introduced onto the market in several countries 50 years ago; however, the portfolio of contraceptive methods remains restricted with regards to their steroid composition, their cost, and their ability to satisfy the requirements of millions of women/couples in accordance with their different reproductive intentions, behaviors, cultures, and settings. Methods: A literature review was conducted using Medline, Embase, and Current Contents databases, up to September 1, 2013 to identify publications reporting new contraceptives in development using combinations of the search terms: contraception, contraceptives, oral contraceptives, patch, vaginal ring, implants, intrauterine contraceptives, and emergency contraception (EC. Also, several experts in the field were also consulted to document ongoing projects on contraception development. Additionally, the Clinicaltrial.gov website was searched for ongoing studies on existing contraceptive methods and new and emerging female contraceptives developed over the past 5 years. Information was also obtained from the pharmaceutical industry. Results: Early sexual debut and late menopause means that women may require contraception for up to 30 years. Although oral, injectable, vaginal, transdermal, subdermal, and intrauterine contraceptives are already available, new contraceptives have been developed in an attempt to reduce side effects and avoid early discontinuation, and to fulfill women's different requirements. Research efforts are focused on replacing ethinyl-estradiol with natural estradiol to reduce thrombotic events. In addition, new, less androgenic progestins are being introduced and selective progesterone receptor

Ovarian epithelial cancers are among the most lethal women's cancers. There is no doubt about the preventive role of oral contraceptive pills (OCPs) in development of ovarian cancers. But, there are limited numbers of studies to address the effect of these agents on the number of cortical inclusion cysts (CICs), their epithelial type and suppression of the metaplastic phenomenon by these pills. The aim of this study was to clarify the role of these agents in the prevention of these cyst formation and tubal metaplasia and also examine the mesenchymal-epithelial transition theory in this context by immunohistochemical methods. The representative section(s) of ovarian cortex from a total number of 201 consecutive total abdominal hysterectomy with bilateral or unilateral salpingo-oophorectomy specimens were examined for mean number of CICs and their epithelial type between two groups of the patients. Group A included the patients who were on oral contraceptive pills for more than 5 years. All of the subjects with other contraceptive methods or a history of less than 5 years contraceptive pills usage were stratified in group B. Sections from 20 cases in which more than five inclusion cysts were found, were selected for IHC staining with calretinine and PAX8 as markers for mesothelium and mullerian epithelium respectively. The mean age of the patients was 51.67 years with no significant differences between two groups. The mean number of cysts were 1.27 and 3.23 in group A and B respectively (P =0.0001). Similarly the mean number of CICs, lined by tubal epithelium, was significantly different between two groups (0.65 vs 2.65, P =0.0001). In IHC staining 123 out of 150 CICs (82 %) were PAX+ while only 7 CICs (4.8 %) showed positive reaction for calretinin irrespective of type of epithelium. Our findings showed that the use of OCP for more than five years in women, significantly prevents development of cortical inclusion cysts in the ovaries which lined by tubal

The effects of contraception on female poverty.

Browne, Stephanie P; LaLumia, Sara

Poverty rates are particularly high among households headed by single women, and childbirth is often the event preceding these households' poverty spells. This paper examines the relationship between legal access to the birth control pill and female poverty. We rely on exogenous cross-state variation in the year in which oral contraception became legally available to young, single women. Using census data from 1960 to 1990, we find that having legal access to the birth control pill by age 20 significantly reduces the probability that a woman is subsequently in poverty. We estimate that early legal access to oral contraception reduces female poverty by 0.5 percentage points, even when controlling for completed education, employment status, and household composition.

We prospectively examined the influence of young women's depression and psychological stress symptoms on their weekly contraceptive method use. We examined data from 689 women ages 18-20 years participating in a longitudinal cohort study. Women completed 8,877 weekly journals over the first year, which assessed reproductive, relationship, and health information. We focused on baseline depression (Center for Epidemiologic Studies-Depression Scale) and stress (Perceived Stress Scale) symptoms and weekly contraceptive method use. Analyses used multivariate random effects and multinomial logistic regression. Approximately one quarter of women exhibited moderate/severe depression (27%) and stress (25%) symptoms at baseline. Contraception was not used in 10% of weekly journals, whereas coital and noncoital methods were used in 42% and 48% of weeks, respectively. In adjusted models, women with moderate/severe stress symptoms had more than twice the odds of contraception nonuse than women without stress (odds ratio [OR] 2.23, confidence interval [CI] 1.02-4.89, p = .04). Additionally, women with moderate/severe depression (RR .52, CI .40-.68, p contraceptives (OCs; reference category). Women with stress symptoms also had higher relative risks of using condoms (RR 1.17, CI 1.00-1.34, p = .02) and withdrawal (RR 1.29, CI 1.10-1.51, p = .001) than OCs. The relative risk of dual versus single method use was also lower for women with stress symptoms. Women's psychological symptoms predicted their weekly contraceptive nonuse and use of less effective methods. Further research can determine the influence of dynamic psychological symptoms on contraceptive choices and failures over time. Copyright © 2013 Society for Adolescent Health and Medicine.

Chabbert-Buffet, Nathalie; Ouzounian, Sophie; Kairis, Axelle Pintiaux; Bouchard, Philippe

2008-09-01

Currently developed progesterone receptor modulators (PRMs) are steroid-derived compounds with mild or potent antiprogestin activity. PRMs may exert a contraceptive activity by different mechanisms such as blockade of ovulation and endometrial desynchronization. Their potential clinical applications are manifold and are very promising in major public health areas, including emergency contraception, long term oestrogen-free contraception (administered alone, or in association with a progestin-only pill to improve bleeding patterns), endometriosis and myoma treatment. The mechanisms of their anti-ovulatory effects and of the endometrial modifications elicited during long term PRM treatment are still not fully elucidated. In future clinical applications, PRMs will be administered orally, via intrauterine systems or vaginal rings.

Introduction: To evaluate changes of contrast medium enhancement of the breast parenchyma due to menstrual cycle in healthy volunteers with oral contraceptive use in MR-imaging of the breast. Material and Methods: 15 healthy volunteers (age: 22 - 36, mean 28,2) without breast disease were examined two times during one menstrual cycle (days 7 - 14 and days 21 - 2). Two volunteers were examined only in the second part of the cycle (days 21 - 2). All volunteers used oral contraceptives for more than 6 month continuously. Examinations were performed with a 0,5 T magnet (dynamic 3D-gradient echo protocol with subtraction postprocessing). We evaluated the number of enhancing foci and the parenchymal contrast medium enhancement during the different phases of the cycle by region of interest. Results: Only a total of two enhancing foci were found in 2 of 17 volunteers. Time/signal intensity diagrams in these both cases were not suspicious ( [de

Emergency contraception - Potential for women′s health

Full Text Available Emergency contraception (EC is a safe and effective method which is used to prevent unwanted pregnancy after unprotected sexual intercourse. Many of the unwanted pregnancies end in unsafe abortions. The search for an ideal contraceptive, which does not interfere with spontaneity or pleasure of the sexual act, yet effectively controls the fertility, is still continuing. Numerous contraceptive techniques are available, yet contraceptive coverage continues to be poor in India. Thus, even when not planning for a pregnancy, exposure to unprotected sex takes place often, necessitating the use of emergency contraception. This need may also arise due to failure of contraceptive method being used (condom rupture, diaphragm slippage, forgotten oral pills or following sexual assault. Emergency contraception is an intervention that can prevent a large number of unwanted pregnancies resulting from failure of regular contraception or unplanned sexual activity, which in turn helps in reducing the maternal mortality and morbidity due to unsafe abortions. However, a concern has been expressed regarding repeated and indiscriminate usage of e-pill, currently the rational use of emergency contraception is being promoted as it is expected to make a significant dent in reducing the number of unwanted pregnancies and unsafe abortions. In fact, since the introduction of emergency contraception, the contribution of unsafe abortion towards maternal mortality has declined from 13 to 8 per cent.

Cyclooxygenase-2 (COX-2) inhibitors reduce prostaglandin synthesis and disrupt essential reproductive processes. Ultrasound studies in women demonstrated that oral COX-2 inhibitors can delay or prevent follicle collapse associated with ovulation. The goal of this study was to determine if oral administration of a COX-2 inhibitor can inhibit reproductive function with sufficient efficacy to prevent pregnancy in primates. The COX-2 inhibitor meloxicam (or vehicle) was administered orally to proven fertile female cynomolgus macaques using one emergency contraceptive model and three monthly contraceptive models. In the emergency contraceptive model, females were bred with a proven fertile male once 2±1 days before ovulation, returned to the females' home cage, and then received 5 days of meloxicam treatment. In the monthly contraceptive models, females were co-caged for breeding with a proven fertile male for a total of 5 days beginning 2±1 days before ovulation. Animals received meloxicam treatment (1) cycle days 5-22, or (2) every day, or (3) each day of the 5-day breeding period. Female were then assessed for pregnancy. The pregnancy rate with meloxicam administration using the emergency contraception model was 6.5%, significantly lower than the pregnancy rate of 33.3% when vehicle without meloxicam was administered. Pregnancy rates with the three monthly contraceptive models (75%-100%) were not consistent with preventing pregnancy. Oral COX-2 inhibitor administration can prevent pregnancy after a single instance of breeding in primates. While meloxicam may be ineffective for regular contraception, pharmacological inhibition of COX-2 may be an effective method of emergency contraception for women. COX-2 inhibitors can interfere with ovulation, but the contraceptive efficacy of drugs of this class has not been directly tested. This study, conducted in nonhuman primates, is the first to suggest that a COX-2 inhibitor may be effective as an emergency contraceptive. �

Full Text Available There are a number of disadvantages inherent in all oral hormonal contraceptives: need for daily administration, fluctuations of hormone levels throughout the day, metabolism in the gastrointestinal tract, the effect of the first passage through the liver. All this became a prerequisite to the creation of prolonged oral hormonal methods of contraception, which would be devoid of these shortcomings. One of such method of hormonal contraception is intravaginal hormonal system. The aim was to determine the safety and efficacy of its use in women of reproductive age with overweight. 43 women were included. State of lipid metabolism, changes of the hemostatic system, blood pressure and weight fluctuations in the past 6 months of using intravaginal hormonal contraceptive system were studied. Results. It is established that hormonal intravaginal contraceptive ring gives minimal metabolic effects. Conclusion. This suggests that this ring can be used successfully in patients with excessive body mass, because there is no effect of the ring on hemostasis, lipid metabolism and body weight.

Heskamp, Marie-Luise S; Schramm, Georg A K

2010-01-01

This study investigated the effects of the low-dose combined oral contraceptive (COC) 2.0 mg chlormadinone acetate (CMA)/0.03 mg ethinylestradiol (EE) (Belara, Balanca) on cycle-related physical and emotional disorders in women >or=25 years of age. A prospective, non-interventional, observational study of 3772 women over six cycles was conducted in 303 office-based gynecological centers throughout Germany. CMA/EE provided high contraceptive efficacy with a Pearl index of 0 (95% confidence interval=0.00-0.22) and was generally well tolerated, with no statistically significant weight changes during the observation period (p=.147). CMA/EE intake resulted in a statistically significant improvement in cycle-related physical and emotional symptoms, with a 67% overall reduction in sum score for number and intensity of cycle-related symptoms per patient. The results of this study in women >or=25 years of age support previous findings that 2.0 mg CMA/0.03 mg EE is an effective low-dose COC, with an excellent tolerability profile, with the additional benefits of significantly reducing both cycle-related physical and emotional symptoms (pcontraceptive treatment. Further research is warranted.

Pregnancy among study participants remains a challenge for trials of new HIV prevention agents despite promotion and provision of contraception. We evaluated contraceptive use, pregnancy incidence, and study drug adherence by contraceptive method among women enrolled in the FEM-PrEP trial of once-daily oral tenofovir disoproxil fumarate and emtricitabine (TDF-FTC) for HIV prevention. We required women to be using effective non-barrier contraception at enrollment. At each monthly follow-up visit, women were counseled on contraceptive use and tested for pregnancy. TDF-FTC adherence was determined by measuring plasma drug concentrations at 4-week intervals. We used Cox proportional hazards models to assess factors associated with incident pregnancy and multivariate logistic regression to examine the relationship between contraceptive method used at enrollment and TDF-FTC adherence. More than half of women were not using effective contraception before enrollment. Ninety-eight percent of these women adopted either injectable (55%) or oral (43%) contraceptives. The overall pregnancy rate was 9.6 per 100 woman-years. Among injectable users and new users of combined oral contraceptives (COCs), the rates were 1.6 and 35.1, respectively. New users of injectables had significantly greater odds of adhering to TDF-FTC than new COC users [odds ratio (95% confidence interval): 4.4 (1.7 to 11.6), P = 0.002], existing COC users [3.1 (1.3 to 7.3), P = 0.01], and existing injectable users [2.4 (1.1 to 5.6), P = 0.04]. Women using COCs during FEM-PrEP, particularly new adopters, were more likely to become pregnant and less likely to adhere to study product than injectable users. HIV prevention trials should consider requiring long-acting methods, including injectables, for study participation.

Full Text Available Introduction: Unintended pregnancy is a worldwide problem that affects women, their families, and society. Unintended pregnancy can result from contraceptive failure, non-use or use mistake of contraceptive Methods: This study examined the Frequency and pattern of contraceptive method use in unintended pregnancy women reffering to health and medical center of Hamadan medical science university in Iran. Design and setting: A descriptive study was conducted at health and medical center of Hamadan medical science in Iran. Data were collected using a questionnaire in 2006 from a convenience sample of 900 unintended pregnancy women . The survey included measures of demographic variables, type and pattern of contraceptive method use. Data were analyzed by Chi square and t-test using SPSS. Results: Of the 900 participants, 93.9% had used contraceptive methods. The most common contraceptive method use in unintended pregnancy women were oral contraceptive pills 38.1% , natural method 31.9%, condom 19.8%, breastfeeding 4.4%, IUD 3.6%, emergency 1.9% and rhythm 0.4%. The most common problem in contraceptive use were irregular and incorrectly use in hormonal methods and condom users, no control in IUD users and mistake in date calculation in rhythmic users. Conclusion: The majority of participants had used contraceptive methods but have unintended pregnancy. More education is needed in this subject.

Objectives. We examined the cost-effectiveness of contraceptive methods dispensed in 2003 to 955 000 women in Family PACT (Planning, Access, Care and Treatment), California's publicly funded family planning program. Methods. We estimated the number of pregnancies averted by each contraceptive method and compared the cost of providing each method with the savings from averted pregnancies. Results. More than half of the 178 000 averted pregnancies were attributable to oral contraceptives, one fifth to injectable methods, and one tenth each to the patch and barrier methods. The implant and intrauterine contraceptives were the most cost-effective, with cost savings of more than $7.00 for every $1.00 spent in services and supplies. Per $1.00 spent, injectable contraceptives yielded savings of $5.60; oral contraceptives, $4.07; the patch, $2.99; the vaginal ring, $2.55; barrier methods, $1.34; and emergency contraceptives, $1.43. Conclusions. All contraceptive methods were cost-effective—they saved more in public expenditures for unintended pregnancies than they cost to provide. Because no single method is clinically recommended to every woman, it is medically and fiscally advisable for public health programs to offer all contraceptive methods. PMID:18703437

Full Text Available Abstract Background In Curaçao is a high incidence of unintended pregnancies and induced abortions. Most of the induced abortions in Curaçao are on request of the woman and performed by general practitioners. In Curaçao, induced abortion is strictly prohibited, but since 1999 there has been a policy of connivance. We present data on the relevance of economic and socio-cultural factors for the high abortion-rates and the ineffective use of contraception. Methods Structured interviews to investigate knowledge and attitudes toward sexuality, contraception and abortion and reasons for ineffective use of contraceptives among women, visiting general practitioners. Results Of 158 women, 146 (92% participated and 82% reported that their education on sexuality and about contraception was of good quality. However 'knowledge of reliable contraceptive methods' appeared to be - in almost 50% of the cases - false information, misjudgements or erroneous views on the chance of getting pregnant using coitus interruptus and about the reliability and health effects of oral contraceptive pills. Almost half of the interviewed women had incorrect or no knowledge about reliability of condom use and IUD. 42% of the respondents risked by their behavior an unplanned pregnancy. Most respondents considered abortion as an emergency procedure, not as contraception. Almost two third experienced emotional, physical or social problems after the abortion. Conclusions Respondents had a negative attitude toward reliable contraceptives due to socio-cultural determined ideas about health consequences and limited sexual education. Main economic factors were costs of contraceptive methods, because most health insurances in Curaçao do not cover contraceptives. To improve the effective use of reliable contraceptives, more adequate information should be given, targeting the wrong beliefs and false information. The government should encourage health insurance companies to reimburse

Despite the widespread availability of highly effective methods of contraception, unintended pregnancy is common. Unplanned pregnancies have been linked to a range of health, social and economic consequences. Emergency contraception reduces risk of pregnancy after unprotected intercourse, and represents an opportunity to decrease number of unplanned pregnancies and abortions. Emergency contraception pills (ECP) prevent pregnancy by delaying or inhibiting ovulation, without interfering with post fertilization events. If pregnancy has already occurred, ECPs will not be effective, therefore ECPs are not abortificants. Ulipristal acetate (17alpha-acetoxy-11beta-(4N-N,N-dymethilaminophenyl)-19-norpregna--4,9-diene-3,20-dione) is the first drug that was specifically developed and licensed for use as an emergency contraceptive. It is an orally active, synthetic, selective progesterone modulator that acts by binding with high affinity to the human progesterone receptor where it has both antagonist and partial agonist effects. It is a new molecular entity and the first compound in a new pharmacological class defined by the pristal stem. Up on the superior clinical efficacy evidence, UPA has been quickly recognized as the most effective emergency contraceptive pill, and recently recommended as the first prescription choice for all women regardless of the age and timing after intercourse. This article provides literature review of UPA and its role in emergency contraception.

[Hypertension in women (contraception and menopause].

Science.gov (United States)

Beaufils, M

2000-11-01

There are three circumstances where hypertension develops specifically in women: oral contraception, pregnancy, and menopause. Oral contraception usually shifts the blood pressure moderately upwards, but hypertension appears in less than 5% of women. Still it may (rarely) be very severe. Hypertension is poorly related to the dosage of the estrogenic compound, but rather to the nature and dosage of the progestive part. This hypertension does not significantly increase the cardiovascular risk of these women. The role of menopause itself in the trigging of hypertension remains uncertain. It seems however that confounding factors such as age, body weight, sodium balance and so on explain the increased incidence of hypertension after menopause. The latter is also associated with an increase of cardiovascular risk, which requires adequate treatment. Hormone replacement therapy is not contra-indicated, even in hypertensive patients.

Hormonal contraceptives and cerebral venous thrombosis risk: A systematic review and meta-analysis

Full Text Available Objectives: Use of oral contraceptive pills (OCP has previously been shown to increase the risk of cerebral venous sinus thrombosis (CVST. Whether this risk varies by type of OCP use, duration of use and other forms of hormonal contraceptives is largely unknown. This systematic review and meta-analysis updates the current state of knowledge on these issues.Methods: We performed a search to identify all published studies on the association between hormonal contraceptive use and risk of CVST in women aged 15-50, using MEDLINE, EMBASE, Cochrane systematic review, the Cochrane Center for Clinical Trials and CINAHL. Risk of CVST was estimated using random effects models. Stratification and meta-regression were used to assess heterogeneity. Results: Of 861 studies reviewed for eligibility, quality, and data extraction, 11 were included in the final systematic review. The pooled odds of developing CVST in women of reproductive age taking oral contraceptives was over 7 times higher compared to women not taking oral contraceptives (OR=7.59, 95% CI 3.82 – 15.09. There is some indication that third generation OCPs may confer a higher risk of CVST than second generation OCPs, but this remains controversial. Data is insufficient to make any conclusions about duration of use and other forms of hormonal contraceptives and risk of CVST. Conclusions: OCP use increases the risk of developing CVST in women of reproductive age. Better studies are needed to determine if duration and type of hormonal contraceptive use modifies this risk.

Langerhans cells (LCs) are effective antigen-presenting cells that function as "custodians" of mucosa, modifying the immune system to pathogen entry, and tolerance to self-antigen and commensal microbes. A reduction in number of LCs in human immunodeficiency virus (HIV)-positive individuals may predispose to local mucosal infections. To quantitatively determine the number of oral mucosal LCs in HIV/acquired immunodeficiency syndrome HIV/acquired immunodeficiency syndrome (AIDS) associated oral Kaposi sarcoma (KS) with/without oral candidiasis (OC) and to define in situ interrelationships between the cells, OC, and HIV infection. Thirty-two periodic acid-Schiff. (PAS) stained histologic sections of palatal HIV/AIDS associated KS with intact oral epithelium were examined for Candida and divided into two groups: . (1) KS coinfected with Candida and. (2) KS noninfected with Candida. Sections were immunohistochemically stained with CD1a. The standard length of surface epithelium was measured and number of positively stained LCs counted per unit length. Control cases included non-Candida infected palatal mucosa overlying pleomorphic adenoma. (PA) and oral mucosa infected with Candida in otherwise healthy individuals. LC number per unit length of surface epithelium was statistically significantly greatest in uninfected PA mucosa and lowest in KS coinfected with Candida (P = 0.0001). A statistically significant difference was also noted between uninfected PA mucosa and non-Candida infected KS (P = 0.0014), in KS coinfected with Candida and non-infected KS (P = 0.0035), between OC and PA (P = 0.0001), and OC and KS coinfected with Candida (P = 0.0247). LC numbers are significantly reduced in oral tissues of HIV/AIDS infected patients by Candida infection when compared to oral tissues without.

Full Text Available Background/Aim. Ovarian cancer (OC comprises 3% of all cancers, but it is the fifth most common cause of cancer death in women. The aim of this case-control study was to determine the risk factors for OC in the female population of Belgrade, Serbia. Methods. A total of 80 consecutive patients were enrolled in the study between 2006 and 2008 in two national referral centers for OC in Serbia. The control subjects were recruited during the regular gynecological check-ups in the Public Health Center of the corresponding municipalities. All the study participants were interviewed during their visits to the above mentioned institutions by two physicians using the same questionnaire. In order to analyze the influence of specific exposure to the risk of the disease, we categorized variables according to the cut-off values. Odds ratios (OR and 95% confidence intervals (95% CI were calculated separately for each variable using univariate conditional logistic regression analysis. Results. There were no statistically significant differences in educational level, years of schooling, occupational and employment status between patients with OC and women in the control group. Oral contraceptives use and other contraceptive methods (condoms, mechanical contraceptive devices were highly statistically significantly more frequent among women in the control group (OR = 0.2, 95% CI 0.1-0.7, p = 0.005; OR = 0.1, 95% CI 0.01-0.5, p = 0.001, respectively. The patients with OC practiced sports for 6.3 ± 2.1 years, and controls for 11.8 ± 9.9 years. Sport and recreation activities were statistically significantly protective (OR = 0.2, p = 0.011; OR = 0.4, p = 0.019. Tea consumption on daily basis had a highly statistically significant protective effect (OR = 0.3, p = 0.001. Conclusions. Oral contraceptives use and physical activity were independent protective factors for OC in this study.

Advances in Male Contraception

Despite significant advances in contraceptive options for women over the last 50 yr, world population continues to grow rapidly. Scientists and activists alike point to the devastating environmental impacts that population pressures have caused, including global warming from the developed world and hunger and disease in less developed areas. Moreover, almost half of all pregnancies are still unwanted or unplanned. Clearly, there is a need for expanded, reversible, contraceptive options. Multicultural surveys demonstrate the willingness of men to participate in contraception and their female partners to trust them to do so. Notwithstanding their paucity of options, male methods including vasectomy and condoms account for almost one third of contraceptive use in the United States and other countries. Recent international clinical research efforts have demonstrated high efficacy rates (90–95%) for hormonally based male contraceptives. Current barriers to expanded use include limited delivery methods and perceived regulatory obstacles, which stymie introduction to the marketplace. However, advances in oral and injectable androgen delivery are cause for optimism that these hurdles may be overcome. Nonhormonal methods, such as compounds that target sperm motility, are attractive in their theoretical promise of specificity for the reproductive tract. Gene and protein array technologies continue to identify potential targets for this approach. Such nonhormonal agents will likely reach clinical trials in the near future. Great strides have been made in understanding male reproductive physiology; the combined efforts of scientists, clinicians, industry and governmental funding agencies could make an effective, reversible, male contraceptive an option for family planning over the next decade.

Full Text Available Scientific background: A large proportion of women of reproductive age in Germany use various methods of pregnancy prevention (contraception, among them various hormone-based methods. Hormonal contraceptives may be divided into combined estrogen-progestogen contraceptives (pills, skin patches, vaginal rings, progestogen-only contraceptives (pills, injections, implants, hormone spirals and emergency contraceptives. Research questions: The evaluation addressed the question of benefits and risks of hormonal contraceptives, their economic effects as well as their ethical-social and legal implications.MethodsA systematic literature search was conducted in April 2006 starting from 2000. The evaluation is primarily based on systematic reviews. Results: In perfect use, all hormonal contraceptives excluding emergency contraceptives proved to be the most effective reversible contraceptive methods (rate of unintended pregnancies 0.05% to 0.3%. However, the typical use of oral contraceptives, injections, skin patches, and vaginal rings, which also considers possible application errors, showed a lower contraceptive efficacy (rate of unintended pregnancies 3% to 8%. It was lower than that of copper spirals. The risk of venous thromboembolism increased three to six times in users of hormonal contraceptives, the risks of stroke and myocardial infarction two to three times. The risk declined after discontinuation of use. The effects were estrogen-dose and progestogen-type dependent. The use of hormonal contraceptives showed a relative risk of ovarian and endometrial carcinomas of approximately 0.5 or 0.7, of breast and cervical cancer of approximately 1.2 or 1.6. The effect remained several years after discontinuation of use. The results concerning hepatocellular carcinoma suggested a carcinogenic effect. In women with acne, an improvement due to use of hormonal contraceptives was proven. Cervical chlamydial infections were more frequent in users of hormonal

Full Text Available Abstract Background Young people between the ages of 15 and 24 years are both the most at risk of HIV and the greatest hope for turning the tide against HIV/AIDS. Although various surveys have been done on sexual behaviour of youth in Ethiopia, studies assessing the effect of emergency oral contraceptives on condom utilization of university students are lacking.

Young people between the ages of 15 and 24 years are both the most at risk of HIV and the greatest hope for turning the tide against HIV/AIDS. Although various surveys have been done on sexual behaviour of youth in Ethiopia, studies assessing the effect of emergency oral contraceptives on condom utilization of university students are lacking. A cross-sectional study was conducted in two major universities of Ethiopia from January to May 2011 using structured self administered questionnaire with the aim to assess the effect of introducing oral emergency contraceptive pills on condom utilization and sexual risk taking behaviours among female university students.

Sex hormones can influence the immune defenses of the female genital tract (FGT) and its susceptibility to infections. Here we investigated the effect of different hormonal contraceptives on the production of antimicrobial peptides (AMPs) in different compartments of the female genital mucosa (FGM), secretions and tissue. Cervicovaginal secretions (CVS) and ectocervical tissue samples obtained from women using progesterone intrauterine devices (pIUD) (n = 23) and combined oral contraceptives (COC) (n = 23) were analyzed for the expression and in situ localization of HNP1-3, BD-2, LL-37, SLPI and trappin-2 by ELISA, real-time PCR and immunohistochemistry. Women using COC had significantly lower mRNA levels of BD-2 and trappin-2 in ectocervical tissue than pIUD users. The two groups showed no differences in CVS concentration, as well as similar in situ expression patterns in ectocervical tissue, of all five AMPs. The use of hormonal contraceptives influences AMP expression differently in genital secretions compared to ectocervical tissue. This suggests that the impact of sex hormones on local immune defenses varies in different compartments of the FGM, and likely in different locations across the FGT. © 2014 John Wiley & Sons A/S.

Full Text Available A elevada freqüência de gestação precoce no Brasil e, particularmente, em Teresina (21,5%, Piauí, motivou o presente estudo, cuja meta foi identificar os níveis de conhecimento objetivo e percebido sobre contraceptivos hormonais orais, bem como variáveis reprodutivas e sócio-demográficas preditoras de elevado conhecimento. Realizou-se estudo transversal com 278 adolescentes com idade de 15 a 19 anos de idade, com antecedentes reprodutivos, internadas em quatro maternidades de Teresina, em 2006. Regressão logística foi a base da análise estatística. Quase 98% das adolescentes apresentaram baixo conhecimento tanto objetivo quanto percebido. Apenas o maior número de gestações foi preditor de elevado conhecimento objetivo para anticoncepcionais orais. Os baixos níveis de conhecimento objetivo e percebido das adolescentes sobre o uso de anticoncepcionais orais revelam a suscetibilidade das jovens ao comportamento sexual de risco. Sugere-se a utilização de abordagem mais interativa com os adolescentes para elevar o nível de conhecimento tanto objetivo quanto percebido deles, e assim reduzir a incidência e reincidência da gravidez indesejada na adolescência e suas conseqüências negativas na vida destas jovens e de sua prole.The high rate of early pregnancy in Brazil and particularly in Teresina (21.5%, Piauí State, motivated the current study, the aim of which was to identify levels of objective and perceived knowledge on oral contraceptives, as well as predictive reproductive and socio-demographic variables for high knowledge. A cross-sectional study was performed including 278 teenage mothers (15-19 years, with their childbearing history, admitted to four maternity hospitals in Teresina in 2006. Logistic regression provided the basis for the statistical analysis. Nearly 98% of the adolescent mothers showed low objective and perceived knowledge of oral contraceptives.

The carrier upconversion dynamics in InAs quantum nanostructures are studied for intermediate-band solar-cell applications via ultrafast photoluminescence and photocurrent (PC) spectroscopy based on femtosecond excitation correlation (FEC) techniques. Strong upconverted PC-FEC signals are observed under resonant excitation of quantum well islands (QWIs), which are a few monolayer-thick InAs quantum nanostructures. The PC-FEC signal typically decays within a few hundred picoseconds at room temperature, which corresponds to the carrier lifetime in QWIs. The photoexcited electron and hole lifetimes in InAs QWIs are evaluated as functions of temperature and laser fluence. Our results provide solid evidence for electron–hole–hole Auger process, dominating the carrier upconversion in InAs QWIs at room temperature.

Full Text Available Luis Bahamondes, Ilza Monteiro, Arlete FernandesHuman Reproduction Unit, Department of Obstetrics and Gynecology, School of Medical Sciences and National Institute of Hormones and Women’s Health, University of Campinas, Campinas, BrazilAbstract: The first combined oral contraceptive (OC was launched in the US 50 years ago and was followed by another formulation introduced in Germany one year later. The most common estrogen component in current formulations is ethinylestradiol; however, many concerns have been raised with respect to this estrogen. Although the natural estrogen produced by the ovary, 17-beta estradiol, is the most potent of the estrogens, it is poorly absorbed orally, and previous attempts to use it in combined OCs have been unsuccessful due to the occurrence of irregular bleeding. Recently, a new combined OC was developed containing a natural estrogen, estradiol valerate, and a new progestin, dienogest, in a dynamic 26-day, four-phasic (estrogen stepdown and progestin stepup scheme of administration. In clinical trials, its contraceptive performance was excellent, with good cycle control and bleeding patterns compared with other combined OCs or with placebo. This review focuses predominantly on the use of an estradiol valerate-dienogest combined OC for the treatment of heavy menstrual bleeding. The findings of two large, randomized, controlled trials have shown that this combined OC constitutes an effective treatment for women with heavy menstrual bleeding, representing a new therapeutic option to reduce menstrual blood loss. Further studies are necessary to confirm these data.Keywords: dienogest, estradiol valerate, heavy menstrual bleeding, menorrhagia, contraception

We report polarized Raman scattering and resonant Raman scattering studies on single InAs nanowires. Polarized Raman experiments show that the highest scattering intensity is obtained when both the incident and analyzed light polarizations are perpendicular to the nanowire axis. InAs wurtzite optical modes are observed. The obtained wurtzite modes are consistent with the selection rules and also with the results of calculations using an extended rigid-ion model. Additional resonant Raman scattering experiments reveal a redshifted E1 transition for InAs nanowires compared to the bulk zinc-blende InAs transition due to the dominance of the wurtzite phase in the nanowires. Ab initio calculations of the electronic band structure for wurtzite and zinc-blende InAs phases corroborate the observed values for the E1 transitions.

Based on the data from the survey of 7826 young couples in two districts of Shanghai, we analyzed the acceptability of oral pill, IUD, condom and injection in women. The results showed that 63.4% of subjects were unwilling to use pill and 5.7% were unwilling to use injection, mainly for the reasons that the pill was “harmful tohealth” and the “cause of obesity”; 8.7% of subjects were unwilling to use IUD, mainly for the reasons of the “cause of menorrhagia or spotting” and“being easy to fail”; 6.2% of subjects were unwilling to use condom, mainly for the reasons of “interference with intercourse” and “inconvenience in use”. The most important source of getting the information was “heard from person's talking”.Simple variate and Logistic analysis showed that women's age at marriage, education, occupation, contraceptive knowledge score, history of using the contraceptives,some women's traits etc. affected the acceptability of the contraceptives. The study implies that it is necessary to strengthen provision of contraceptive knowledge for young couples and to make them have correct understanding of the side effects of contraceptives for improving family planning program.

Incarcerated women have had limited access to health care prior to their arrest. Although their incarceration presents an opportunity to provide them with health care, their reproductive health needs have been overlooked. We performed a cross-sectional study of a nationally representative sample of 950 correctional health providers who are members of the Academy of Correctional Health Providers. A total of 405 surveys (43%) were returned, and 286 (30%) were eligible for analysis. Most ineligible surveys were from clinicians at male-only facilities. Of eligible respondents, 70% reported some degree of contraception counseling for women at their facilities. Only 11% provided routine counseling prior to release. Seventy percent said that their institution had no formal policy on contraception. Thirty-eight percent of clinicians provided birth control methods at their facilities. Although the most frequently counseled and prescribed method was oral contraceptive pills, only 50% of providers rated their oral contraceptive counseling ability as good or very good. Contraception counseling was associated with working at a juvenile facility, and with screening for sexually transmitted infections. Contraception does not appear to be integrated into the routine delivery of clinical services to incarcerated women. Because the correctional health care system can provide important clinical and public health interventions to traditionally marginalized populations, services for incarcerated women should include access to contraception.

Emergency contraceptives bring a little peace of mind.

Although emergency contraceptive pills have been prescribed to US women since the discovery of the birth control pill, this regimen has been termed "America's best-kept secret." For fear of legal liability, many providers have been unwilling to prescribe oral contraceptive pills for a purpose other than that for which they are labeled on the packaging. There are indications, however, that access to emergency contraception in the US is improving. PREVEN, the first product to be approved by the US Food and Drug Administration specifically for emergency contraception, was released in 1998. The kit includes a step-by-step information booklet, a pregnancy test, and four birth control pills. In Washington State, collaborative drug agreements between volunteer pharmacists and licensed prescribers enable pharmacists to prescribe emergency contraception pills directly--a move that is estimated to have prevented 207 unintended pregnancies and 103 abortions in less than one year. Planned Parenthood has developed two programs to increase the use of emergency contraception. The first allows clinicians to discuss emergency contraception over the phone with clients (even new ones) and to call in prescriptions to local pharmacies; the second provides women with emergency contraceptive kits to keep on hand in advance of a need for the regimen.

Factors such as personal issues, family, sexuality and sexual partner characteristics are strongly associated with contraceptive continuation among single, nulliparous female adolescents. To determine factors associated to contraceptive maintenance among female nulliparous adolescents. A cohort of 2,811 adolescents, who confidentially requested contraception in a sexual and reproductive health university center from 1990 to 2006 was analyzed. Two years after the request, their clinical records were reviewed to determine the time and length of contraception. Using life table analysis, the variables related to continuation or discontinuation of contraception were identified. Factors associated with a longer contraceptive use were a lower age at the moment of initiating the method, a better academic achievement and aspirations, higher schooling of the partner, higher age of the mother, having an adolescent mother, supervision of permissions by people different than parents and not attending to religious services. Variables associated with a higher risk for abandonment were a higher age of the adolescent, greater number of sexual partners, lack of communication with parents, non-catholic religious affiliation, use of oral hormonal contraceptive, greater number of siblings, commenting sexual issues with relatives or friends, having a partner without academic activity or working and to live without parents. Several personal, familial and environmental factors influence contraceptive use continuity among adolescents.

A study supported by the World Health Organization's Task Force on Postovulatory Methods of Fertility Control compared the efficacy of the Yuzpe and levonorgestrel-only methods of emergency contraception (EC). Enrolled in this double-blind, randomized trial were 1998 women from 21 centers around the world who requested EC within 72 hours of unprotected intercourse. The pregnancy rate was 1.1% for levonorgestrel alone and 3.2% for the combined ethinyl estradiol-levonorgestrel regimen. The crude relative risk of pregnancy was 0.36 (95% confidence interval, 0.18-0.70) for levonorgestrel compared with the Yuzpe regimen. The former method prevented 85% of expected pregnancies, while the latter prevented only 57%. Finally, side effects such as nausea, vomiting, dizziness, and fatigue were significantly less common in the levonorgestrel group. Although these findings document the superiority of the levonorgestrel regimen for EC, the 0.75 mg tablets are not currently manufactured in the US.

Background Oral contraceptive pills (OCPs) are one of the most reliable methods of contraception. However, lack of knowledge about oral contraceptive use and inconsistent pill-taking might result in decreased efficacy. The study reported here aimed to explore women’s knowledge about oral contraceptive use and assess the factors associated with knowledge about OCPs among users. Methods This cross-sectional survey was conducted at King Abdulaziz University Hospital, Jeddah, Saudi Arabia between April and June 2014. We included married, non-pregnant women >18 years old who had used a combined 21-day OCP for at least 3 months prior to recruitment. A questionnaire was used to collect the participants’ demographic information. It also assessed their knowledge about OCPs. Data were entered into and analyzed using SPSS software. Results A total of 357 women were recruited. Of these, 57.7% reported they knew what to do after missing one or two pills, but only 18.3% knew exactly what to do after missing more than two pills consecutively. Postgraduate women had a significantly higher knowledge score than illiterate women (P=0.002) and those who had completed at least primary education (P=0.001). Conversely, there was no difference in knowledge scores between Saudi and expatriate women (P=0.2). Monthly incomes (P=0.2) and mode of OCP selection (P=0.2) were also not significantly associated with knowledge scores. Conclusion Women had poor knowledge about OCP use. Appropriate measures should be taken to educate women about proper oral contraceptive use. PMID:25792813

To describe predictors of contraceptive method discontinuation and switching behaviours among HIV-positive couples receiving couples' voluntary HIV counselling and testing services in Lusaka, Zambia. Couples were randomized in a factorial design to two-family planning educational intervention videos, received comprehensive family planning services and were assessed every 3 months for contraceptive initiation, discontinuation and switching. We modelled factors associated with contraceptive method upgrading and downgrading via multivariate Andersen-Gill models. Most women continued the initial method selected after randomization. The highest rates of discontinuation/switching were observed for injectable contraceptive and intrauterine device users. Time to discontinuing the more effective contraceptive methods or downgrading to oral contraceptives or condoms was associated with the women's younger age, desire for more children within the next year, heavy menstrual bleeding, bleeding between periods and cystitis/dysuria. Health concerns among women about contraceptive implants and male partners not wanting more children were associated with upgrading from oral contraceptives or condoms. HIV status of the woman or the couple was not predictive of switching or stopping. We found complicated patterns of contraceptive use. The predictors of contraception switching indicate that interventions targeted to younger couples that address common contraception-related misconceptions could improve effective family planning utilization. We recommend these findings be used to increase the uptake and continuation of contraception, especially long-acting reversible contraceptive (LARC) methods, and that fertility goal based, LARC-focused family planning be offered as an integral part of HIV prevention services.

evidence supporting a causal association between combination oral contraceptives or a combination skin patch and weight change. Most comparisons of different combination contraceptives showed no substantial difference in weight. In addition, discontinuation of combination contraceptives because of weight change did not differ between groups where this was studied. Available evidence was insufficient to determine the effect of combination contraceptives on weight, but no large effect was evident. Trials to evaluate the link between combination contraceptives and weight change require a placebo or non-hormonal group to control for other factors, including changes in weight over time.

To assess the knowledge, attitude regarding family planning and the practice of contraceptives among rural women. One-hundred women between the ages 15-45, living with their husbands and coming from rural area (villages) were interviewed. Women who were pregnant, had a child younger than 2 years, or had any medical disorder were excluded. Their knowledge, attitude and practice on contraceptives were evaluated with the help of a predesigned questionnaire. The other variables used were the age of women, parity and educational status. Descriptive analysis was conducted to obtain percentages. Out of 100 interviewed women with mean age of 29.7 years, 81(81%) had some knowledge about family planning methods. The media provided information of contraceptives in 52 out of 81 (64%) women. Regarding the usage of contraceptive methods, only 53 (53%) of the respondents were using some sort of contraception. Barrier method (condoms) was in practice by 18 (33.9%) and 12 (22.6%) of women had already undergone tubal ligation. The women using injectables and intrauterine contraceptive devices were 10 (18.8%) and 7 (13.2%) respectively. Six were using oral contraceptive pills (11.3%). Positive attitude towards contraception was shown by 76 (76%) of them, while 41(41%) stated their husbands positive attitude towards contraception. In the present study, there was a low contraceptive use among women of rural origin despite good knowledge. Motivation of couples through media and health personnel can help to achieve positive attitude of husbands for effective use of contraceptives. (author)

More than 150 million women become pregnant in developing countries annually and an estimated 287,000 die from pregnancy-related causes. Contraception is vital to prevent unnecessary maternal deaths, as well as sexually transmitted infections. The objective of this study was to investigate preferred contraceptive methods and the factors that influence contraceptive choice among women in Kelantan, Malaysia. A cross-sectional study using interview-based questionnaires was conducted, during July and August 2009, in local family planning clinics in Kelantan. The questionnaire was administered to adult women (age 20-50). Prevalence of unplanned pregnancies was high (48%). Contraceptive preference was Depo contraceptive injection (32%), oral contraceptive pills (27%), intrauterine devices (15%) and contraceptive implants (12%); 9% used condoms. Only 2% used contraception to protect against sexually transmitted infections or HIV/AIDS. Younger women (OR 0.90; 95% CI 0.807-0.993) were more likely to use contraception. In conclusion, non-interrupted contraceptive methods were preferred. More than 60% would stop using contraception if it interrupted intercourse. From both a public health and infectious disease perspective, this is extremely worrying.

Background Previous studies indicate that the sexual beliefs and mores of students in medical professions may influence their capacity to care for patients’ sexuality and contraception issues. Students also represent a large sample of reproductive-age individuals. In this study, we examined contraceptive usage patterns in North American medical students. Study Design Students using online medical student social and information networks enrolled in allopathic and osteopathic medical schools in North America between February and July of 2008 were invited to participate via email and published announcements in an Internet-based survey consisting of a questionnaire that assessed ethnodemographic factors, year in school and sexual history. We also collected information about current use of contraceptive and barrier methods. Descriptive statistics and logistic regression were utilized to analyze responses. Results Among our 2269 complete responses, at least one form of contraception was being utilized by 71% of men and 76% of women. Condoms were the most popular form of contraceptive, utilized by 1011 respondents (50% of men and 40% of women). Oral contraceptive pills were the contraceptive of choice for 34% of men and 41% of women. Decreased rates of contraception use were associated with being black or Asian, not being in a relationship and having more sexual dysfunction in female respondents. Students who reported comfort discussing sexual issues with patients were more likely to use effective contraceptive methods themselves. Ten percent of this of sexually active medical students was not currently using contraception. Conclusions There are significant differences in contraceptive use based on demographics, even at the highest education levels. The personal contraception choices of medical students may influence their ability to accurately convey information about contraception to their patients. In addition, medical students may personally benefit from improved

In this talk the authors will discuss their progress using InAs heterostructures to produce spin-polarized injection and detection, as well as manipulation of coherent spin-polarized electrons for a spin-based FET (SpinFET). High-quality n-type InAs heterostructures demonstrate many favorable characteristics necessary to the study of spin dynamics, including 2DEG's with small effective mass (m* = 0.023) and large g-factor (g = -15). Previously, high-mobility InAs heterostructures have been demonstrated in which electrons pass ballistically over hundreds of nanometers up to room temperature. Our devices seek to exploit the strong Spin-Orbit effect present in InAs to manipulate coherent spin-polarized electrons during transport, by producing perpendicular electric field using isolated top-gates fabricated over the electron transport region.

To determine current contraceptive management by general practitioners in Australia. Analysis of data from a random sample of 3910 Australian GPs who participated in the Bettering the Evaluation and Care of Health (BEACH) survey, a continuous cross-sectional survey of GP activity, between April 2007 and March 2011. Consultations with female patients aged 12-54 years that involved all forms of contraception were analysed. GP and patient characteristics associated with the management of contraception; types of contraception used; rates of encounters involving emergency contraception. Increased age, ethnicity, Indigenous status and holding a Commonwealth Health Care Card were significantly associated with low rates of encounters involving management of contraception. The combined oral contraceptive pill was the most frequently prescribed method of contraception, with moderate prescription of long-acting reversible contraception (LARC), especially among women aged 34-54 years. Rates of consultations concerned with emergency contraception were low, but involved high rates of counselling, advice or education (48%) compared with encounters for general contraception (> 20%). A shift towards prescribing LARC, as recommended in clinical guidelines, has yet to occur in Australian general practice. Better understanding of patient and GP perspectives on contraceptive choices could lead to more effective contraceptive use.
