Ilovayskaya I, Zektser V. Hypogonadism as a consequence of craniopharyngioma in female patients: comparison of childhood and adult onset and effects of estrogen replacement therapy. Endocrine 2024; 85:1425-1434. [PMID: 38761348 DOI: 10.1007/s12020-024-03872-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Accepted: 05/09/2024] [Indexed: 05/20/2024]
Abstract
PURPOSE (1) to compare clinical, biochemical features in female patients with hypoestrogenism due to childhood- and adult-onset CP; (2) to reveal effects of estrogen replacement therapy in female patients with childhood-onset CP. METHODS Thirty-seven women that received specific treatment for CP in the period from 1980 to 2019 were recruited: 21 with childhood-onset and 16 with adult-onset CP. Clinical and hormonal characteristics were evaluated. Seventeen-beta-estradiol 2 mg and dydrogesterone 10 mg in sequential regiment was used in 18 childhood-onset cases. Mean follow-up was 31 months. RESULTS Amenorrheic women with childhood- and adult-onset CP presented with the same complaints except for lack of genital hair and breast hypoplasia, which were common in patients with childhood-onset CP. BMI was lower in childhood-onset CP group, as was the proportion of overweight patients. They had more favorable lipid profile. The levels of estradiol, testosterone and DHEA-S were low and did not differ. Uterine and ovary volumes were reduced in all patients, but the decline was noticeable in the childhood-onset group. Mineral bone density of lumbar vertebrae was diminished in childhood-onset group. Estrogen therapy in these patients led to clinical improvement: increase in BMD in lumbar spine without negative changes in BMI and/or lipid profile. CONCLUSIONS Study showed that women with childhood-onset CP had less negative metabolic changes. However, they have more pronounced breast and uterus hypoplasia and lower BMD in lumbar spine. The estrogen replacement therapy led to clinical improvement and BMD increase in lumbar spine without increase of BMI and/or lipid profile changes.

Differential changes in appetite hormones post-prandially based on menstrual cycle phase and oral contraceptive use: A preliminary study. Appetite 2024; 198:107362. [PMID: 38636667 DOI: 10.1016/j.appet.2024.107362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 04/01/2024] [Accepted: 04/14/2024] [Indexed: 04/20/2024]
Abstract
This was a preliminary study that examined whether appetite regulation is altered during the menstrual cycle or with oral contraceptives. Ten naturally cycling females (NON-USERS) and nine tri-phasic oral contraceptive using females (USERS) completed experimental sessions during each menstrual phase (follicular phase: FP; ovulatory phase: OP; luteal phase: LP). Appetite perceptions and blood samples were obtained fasted, 30, 60, and 90 min post-prandial to measure acylated ghrelin, active glucagon-like peptide-1 (GLP-1), and total peptide tyrosine tyrosine (PYY). Changes were considered important if p < 0.100 and the effect size was ≥medium. There appeared to be a three-way (group x phase x time) interaction for acylated ghrelin where concentrations appeared to be greater in USERS versus NON-USERS during the OP 90-min post-prandial and during the LP fasted, and 90-min post-prandial. In USERS, ghrelin appeared to be greater 90-min post-prandial in the OP versus the FP with no other apparent differences between phases. There were no apparent differences between phases in NON-USERS. There appeared to be a three-way interaction for PYY where concentrations appeared to be greater in USERS during the FP 60-min post-prandial and during the OP 30-min post-prandial. In USERS PYY appeared to be greater 60-min post-prandial during the OP versus the LP with no other apparent differences. There were no apparent differences between phases in NON-USERS. There appeared to be no effect of group or phase on GLP-1, or appetite perceptions. These data demonstrate small effects of menstrual cycle phase and oral contraceptive use on the acylated ghrelin and total PYY response to a standardized meal, with no effects on active GLP-1 or perceived appetite, though more work with a large sample size is necessary.

Hormones (Athens) 2024; 23:277-286.

Abstract
Ovarian cancer is the seventh most common cancer in women in the world, with an estimated worldwide mortality of over 207'000 women every year. This cancer, due to the current lack of adequate screening techniques, is commonly diagnosed late and has a poor prognosis. The oral contraceptive pill is considered the most effective prevention strategy for ovarian cancer in the general population, being associated with a decreased incidence while also having a substantial positive impact on the mortality rate, which is reduced by up to 50%. BRCA1 and BRCA2 germline mutated women have an augmented risk of ovary and breast cancer: despite international guidelines that consider prophylactic surgery as the gold standard for ovarian cancer prevention, there are currently no effective non-invasive preventive methods. In BRCA1\2 mutated patients, clinicians should weigh the benefits of contraceptive pills against the risk of long-term thromboembolic side effects and hormonal malignancies such as breast and cervical cancer. A multidisciplinary team should counsel patients on the most appropriate risk-reduction strategy tailored to their needs and expectations, proposing the oral contraceptive pill to selected patients after balancing the risks of adverse effects and the benefits on both contraception and chemoprevention.

Abstract
Background In Brazil, where approximately 48.7 million women are of reproductive age, understanding contraceptive practices is essential for addressing public health challenges. This study evaluated into the knowledge, usage, and perceptions of contraceptive methods among Brazilian women, highlighting the influence of socioeconomic and demographic factors on their choices. Methods We conducted a cross-sectional survey with a representative sample of 2000 Brazilian women aged 18-49 years. The questionnaire collected detailed information on their awareness, preferences, and utilization of various contraceptive methods, alongside demographic and socioeconomic data. Results Oral contraceptives, condoms, injectables, and intrauterine devices (IUDs) were the most recognized methods. Younger women demonstrated greater awareness of modern methods. Socioeconomic disparities were evident, with lower-income women displaying limited knowledge about condoms and IUDs but a higher usage for injectable contraceptives. Oral contraceptives were the most used method, with higher use in the South, and lower in the Central-West and Northeast regions. Satisfaction with current contraceptive methods was high (87.5%), closely associated with personal responsibility in method choice. Although the majority self-financed their contraceptives (63.1%), a significant portion of lower-income women (27.7%) relied on public health care. Physicians' recommendations predominantly influenced contraceptive choice (53.9%), with younger women also guided by other influences. Conclusions Persistent disparities in contraceptive awareness and access highlight the need for educational initiatives and policy interventions. Health care providers play a vital role in facilitating informed contraceptive choices, enhancing the chances of satisfaction with the method.

Abstract
Background Primary dysmenorrhea (PD) is one of the most common reasons that affect the life quality of women during childbearing age. This research aims to explore the efficacy and curative effect characteristics of oral contraceptives and low-power visible-light-activated photodynamic therapy (PDT). Besides investigating the possible mechanism of PDT, we expected to find a treatment model with better efficacy and fewer side effects. Method It was a multicenter, randomized, parallel-controlled study. Eligible participants were randomly assigned to three groups: placebo group, oral contraceptive (Marvelon) group, and the PDT group. They were treated continuously for three menstrual cycles and followed up for two cycles after treatment. The scores of the visual analog scale (VAS) and the concentration of pain-related small molecules in blood before and after treatment were recorded in each group, which can evaluate the therapeutic characteristics of different treatments. Result Both Marvelon and PDT were effective. The effect of Marvelon appears quickly which can significantly relieve symptoms at the beginning, while PDT shows a relatively slow role. There was no significant difference in the final efficacy two cycles after treatment. The therapeutic effect was achieved by reducing the concentrations of prostaglandin 2 (PGE2) and endothelin (ET) in the blood. Conclusion Marvelon and PDT are effective methods for the treatment of PD. The long-term efficacy of the two is similar, while the therapeutic characteristics and the side effects are different. Patients can choose the suitable way according to their individual needs.

Abstract
Background Deep vein thrombosis (DVT) has been reported as an adverse event for patients receiving combined oral contraceptives. Norethindrone/ethinyl estradiol (NET/EE) and drospirenone/ethinyl estradiol (DRSP/EE) are two commonly prescribed combined hormonal oral contraceptive agents used in the United States, differing in their progestin component. Objective The purpose of this study was to determine the association between the progestin component of a combined oral contraceptive and the risk of DVT in patients taking oral contraceptives for birth control using data derived from the FDA Adverse Event Reporting System (FAERS). Methods The risk of DVT was compared between patients that had taken NET/EE with those that had taken the DRSP/EE COC formulation for birth control. In addition, age was assessed as a possible confounder and the outcome severity for those diagnosed with DVT were compared between the two groups. Finally, association rule mining was utilized to identify possible drug-drug interactions that result in elevated DVT risk. Results DVT was the fourth most commonly adverse event reported for patients taking DRSP/EE accounting for 8558 cases and the seventeenth most commonly reported adverse event for NET/EE accounting for 298 cases. Age was found to be a significant confounder for users of DRSP/EE with regards to DVT risk across all age groups assessed: 20 40 (ROR = 3.69, 95% CI 3.37-4.04) However, there was only a statistically significant elevated risk in patients over 40 years of age taking NET/EE (ROR = 1.98, 95% CI 1.36-2.88). Patients that had taken DRSP/EE and the corticosteroid prednisone simultaneously had an approximately 3-fold increase in DVT risk (ROR = 2.77, 95% CI 2.43-3.15) relative to individuals that had only taken DRSP/EE. Conclusion Based on this analysis, there is a higher risk of developing DVT when taking DRSP/EE than when taking NET/EE as hormonal contraception. In addition, a possibly significant drug-drug interaction between different COC formulations and prednisone were identified. This interaction may result in elevated DVT risk due to a synergistic impairment of fibrinolysis and a decrease in plasmin production.

Abstract
Contraception is a practice with extensive and complicated social and scientific histories. From cycle tracking, to the very first prescription contraceptive pill, to now having over-the-counter contraceptives on demand, family planning is an aspect of healthcare that has undergone and will continue to undergo several transformations through time. This review provides a comprehensive overview of current reversible hormonal and non-hormonal birth control methods as well as their mechanism of action, safety, and effectiveness specifically for individuals who can become pregnant. Additionally, we discuss the latest Food and Drug Administration (FDA)-approved hormonal method containing estetrol and drospirenone that has not yet been used worldwide as well as the first FDA-approved hormonal over-the-counter progestin-only pills. We also review available data on novel hormonal delivery through microchip, microneedle, and the latest FDA-approved non-hormonal methods such as vaginal pH regulators. Finally, this review will assist in advancing female contraceptive method development by underlining constructive directions for future pursuits. Information was gathered from the NCBI and Google Scholars databases using English and included publications from 1900 to present. Search terms included contraceptive names as well as efficacy, safety, and mechanism of action. In summary, we suggest that investigators consider the side effects and acceptability together with the efficacy of contraceptive candidate towards their development.

Abstract
Cervical cancer (CC) is caused by persistent infection of human papillomavirus of high oncogenic risk (hr-HPV); however, several cofactors are important in its carcinogenesis, such as smoking, multiparity, and prolonged use of oral hormonal contraceptives (COCs). Worldwide, 16% of women use COCs, whereas in Brazil this rate is of ∼ 30%. The safety and adverse effects of COCs are widely discussed in the literature, including the increase in carcinogenic risk. Due to the existence of several drugs, combinations, and dosages of COCs, it is hard to have uniform information in epidemiological studies. Our objective was to perform a narrative review on the role of COCs use in the carcinogenesis of cervical cancer. Several populational studies have suggested an increase in the incidence of cervical cancer for those who have used COCs for > 5 years, but other available studies reach controversial and contradictory results regarding the action of COCs in the development of CC.

Abstract
Background The associations of oral contraceptive (OC) use with cardiovascular disease (CVD) and all-cause death remains unclear. We aimed to determine the associations of OC use with incident CVD and all-cause death. Methods and Results This cohort study included 161 017 women who had no CVD at baseline and reported their OC use. We divided OC use into ever use and never use. Cox proportional hazard models were used to calculate hazard ratios and 95% CIs for cardiovascular outcomes and death. Overall, 131 131 (81.4%) of 161 017 participants reported OC use at baseline. The multivariable-adjusted hazard ratios for OC ever users versus never users were 0.92 (95% CI, 0.86-0.99) for all-cause death, 0.91 (95% CI, 0.87-0.96) for incident CVD events, 0.88 (95% CI, 0.81-0.95) for coronary heart disease, 0.87 (95% CI, 0.76-0.99) for heart failure, and 0.92 (95% CI, 0.84-0.99) for atrial fibrillation. However, no significant associations of OC use with CVD death, myocardial infarction, or stroke were observed. Furthermore, the associations of OC use with CVD events were stronger among participants with longer durations of use (P for trend<0.001). Conclusions OC use was not associated with an increased risk of CVD events and all-cause death in women and may even produce an apparent net benefit. In addition, the beneficial effects appeared to be more apparent in participants with longer durations of use.

Schneider-Kamp A, Takhar J. Interrogating the pill: Rising distrust and the reshaping of health risk perceptions in the social media age. Soc Sci Med 2023; 331:116081. [PMID: 37441974 DOI: 10.1016/j.socscimed.2023.116081] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 07/04/2023] [Accepted: 07/06/2023] [Indexed: 07/15/2023]
Abstract
Since its introduction in 1960, the combined oral contraceptive pill has become the dominant reversible contraceptive technology for controlling female fertility in spite of early and ongoing ethical, critical medical, and societal disapproval. Over the last decade, prescription rates among young women in Western Europe have declined alongside the rise of social media use. This article investigates the mechanisms underlying this change in contraceptive choices and the role played by social media in this trend. Via exploratory online observation and an in-depth interview study with 19 informants in Germany and Denmark, we find social media consolidates the social construction of hazards associated with the contraceptive pill by reshaping young women's risk perception from questions around drug reliability and safety to those of individual physical, mental, and social well-being. We shed light on how social media contributes to the delegitimation of health professionals such as gynaecologists and general practitioners and adds to wider debates on the erosion of medical authority and the attendant rise of peer influencers. We condense our findings into a framework for health-related attitude formation and decision-making in the social media age, which elucidates how social media amplifies and reshapes societal discourses regarding health-related technologies, choices, and risks.

The influence of the menstrual cycle and hormonal contraceptives on cardiorespiratory fitness in physically active women: A systematic review and meta-analysis. Heliyon 2023; 9:e17049. [PMID: 37484400 PMCID: PMC10361115 DOI: 10.1016/j.heliyon.2023.e17049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Revised: 05/18/2023] [Accepted: 06/06/2023] [Indexed: 07/25/2023] Open
Abstract
Objective To systematically review and summarize the existing evidence related to the influence of the menstrual cycle (MC) and hormonal contraceptive (HC) use on V˙O2max in physically active women. Methods This systematic review and meta-analysis conforms to the PRISMA statement guidelines. Four (sub-)meta-analyses were performed. Two focused on longitudinal studies examining the same women several times to compare the V˙O2max during the different menstrual phases or oral contraceptive (OC) use and withdrawal. Two meta-analyses examined if there is a difference in V˙O2max between OC users and normally menstruating women by analyzing cross-sectional studies assigning physically active women to one of these two groups as well as intervention-based studies (cross-over studies, randomized controlled trials considering only the data of the intervention group) comparing women intra-individually with and without OCs. Results Nine of the included studies (107 women) evaluated the influence of the MC, five studies (69 women) the impact of OCs on V˙O2max, and six studies investigated both topics (88 women). A mean difference of V˙O2max -0.03 ml/kg/min (95%CI -1.06 to 1.01) between the early follicular and luteal menstrual phase was observed. Between the active and inactive phases of OCs, a mean difference of -0.11 ml/kg/min (95%CI -2.32 to 2.10) was found. The inter-individual comparison of naturally menstruating women and OC users showed a mean difference in V˙O2max of 0.23 ml/kg/min (95% CI -2.33 to 2.79) in favor of OC use. The intra-individual comparison of the same women showed a mean decrease in V˙O2max of -0.84 ml/kg/min (95% CI -2.38 to 0.70) after a new start with OCs. Conclusions Our meta-analyses showed no effects of the MC or the OCs on V˙O2max. More high-quality studies are needed determining the MC phases more precisely, including OCs with the current standard formulations and comparing the influence of different progestins.

Variability of the urinary and blood steroid profiles in healthy and physically active women with and without oral contraception. Drug Test Anal 2023; 15:324-333. [PMID: 36414566 DOI: 10.1002/dta.3412] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 11/17/2022] [Accepted: 11/18/2022] [Indexed: 11/24/2022]
Abstract
The steroidal module of the athlete biological passport (ABP) targets the use of pseudo-endogenous androgenous anabolic steroids in elite sport by monitoring urinary steroid profiles. Urine and blood samples were collected weekly during two consecutive oral contraceptive pill (OCP) cycles in 15 physically active women to investigate the low urinary steroid concentrations and putative confounding effect of OCP. In urine, testosterone (T) and epitestosterone (E) were below the limit of quantification of 1 ng/ml in 62% of the samples. Biomarkers' variability ranged between 31% and 41%, with a significantly lesser variability for ratios (except for T/E [41%]): 20% for androsterone/etiocholanolone (p < 0.001) and 25% for 5α-androstane-3α,17β-diol/5ß-androstane-3α,17β-diol (p < 0.001). In serum, markers' variability (testosterone: 24%, androstenedione: 23%, dihydrotestosterone: 19%, and T/A4: 16%) was significantly lower than in urine (p < 0.001). Urinary A/Etio increased by >18% after the first 2 weeks (p < 0.05) following withdrawal blood loss. In contrast, serum T (0.98 nmol/l during the first week) and T/A4 (0.34 the first week) decreased significantly by more than 25% and 17% (p < 0.05), respectively, in the following weeks. Our results outline steroidal variations during the OCP cycle, highlighting exogenous hormonal preparations as confounder for steroid concentrations in blood. Low steroid levels in urine samples have a clear negative impact on the subsequent interpretation of steroid profile of the ABP. With a greater analytical sensitivity and lesser variability for steroids in healthy active women, serum represents a complementary matrix to urine in the ABP steroidal module.

Abstract
Prospective randomized controlled trials on hormonal contraceptive (HC) effects on the brain are rare due to a number of methodological challenges. Thus, much of the evidence on HC effects on the brain comes from cross-sectional studies comparing HC-users to non-users. In interpreting these findings, it is of importance to be aware of potential confounds associated with women's contraceptive choices. Previous studies have discussed age, education, social status, sexual orientation, relationship status, and tolerability of HC. Given the current trend toward a reduction in HC use and increased skepticism toward HC it seems relevant to also identify variables associated with women's attitudes toward HC and whether they may represent confounds for neuroscientific studies. In the present study, we investigated whether women's personality characteristics were associated with their choice to use or not use HC in the present, past and future and the type of HC chosen. 1,391 females aged 18-45 years participated in an online survey including the HEXACO-60 personality questionnaire, as well as two different measures of gender role, and provided information about their current and previous contraceptive status, as well as experiences with and attitudes toward contraceptive use. We compared (i) current, previous and never-users of HC, (ii) prospective users of HC to women who opposed future HC use, and (iii) current users of IUDs to current users of oral contraceptives. Results revealed that associations between personality and the decision to use or not use HC were negligible, while differences in personality were observed corresponding to contraceptive type. Current users of IUDs showed higher agreeableness and extraversion compared to current users of oral contraceptives. The results suggest that personality is more strongly associated to the choice of contraceptive type rather than the choice between hormonal and non-hormonal options.

Effects of oral contraceptive use on muscle strength, muscle thickness, and fiber size and composition in young women undergoing 12 weeks of strength training: a cohort study. BMC Womens Health 2022; 22:150. [PMID: 35538569 PMCID: PMC9092708 DOI: 10.1186/s12905-022-01740-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Accepted: 04/25/2022] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND It is suspected that hormonal fluctuations during menstruation may cause different responses to strength training in women who use oral contraceptives (OC) versus those who do not. However, previous studies that investigated the existence of such differences produced conflicting results. In this study, we hypothesized that OC use has no effect on muscle strength and hypertrophy among women undergoing strength training. Thus, we compared the differences in muscle strength and thickness among women who used OCs and those who did not. METHODS We investigated the influence of OC use on muscle strength (Fmax), muscle thickness (Mtk), type 1-to-type 2 muscle fiber (NO) ratio, muscle fiber thickness (MFT), and nuclear-to-fiber (N/F) ratio. Seventy-four healthy young women (including 34 who used OCs and 40 who did not) underwent 12 weeks of submaximal strength training, after which Fmax was evaluated using a leg-press machine with a combined force and load cell, while Mtk was measured using real-time ultrasonography. Moreover, the NO ratio, MFT, and N/F ratio were evaluated using muscle needle biopsies. RESULTS Participants in the non-OC and OC groups experienced increases in Fmax (+ 23.30 ± 10.82 kg and + 28.02 ± 11.50 kg respectively, p = 0.073), Mtk (+ 0.48 ± 0.47 cm2 and + 0.50 ± 0.44 cm2 respectively, p = 0.888), Fmax/Mtk (+ 2.78 ± 1.93 kg/cm2 and + 3.32 ± 2.37 kg/cm2 respectively, p = 0.285), NO ratio (type 2 fibers: + 1.86 ± 6.49% and - 4.17 ± 9.48% respectively, p = 0.169), MFT (type 2 fibers: + 7.15 ± 7.50 µm and + 4.07 ± 9.30 µm respectively, p = 0.435), and N/F ratio (+ 0.61 ± 1.02 and + 0.15 ± 0.97 respectively, p = 0.866) after training. There were no significant differences between the non-OC and OC groups in any of these parameters (p > 0.05). CONCLUSIONS The effects of 12 weeks of strength training on Fmax, muscle thickness, muscle fiber size, and composition were similar in young women irrespective of their OC use.

Abstract
Most reproductive-aged women are exposed to fluctuating female steroid hormones due to the menstrual cycle or oral contraceptive use. This study investigated the potential effect of the menstrual cycle and combined monophasic oral contraceptive cycle on various aspects of muscle performance. Thirty active females (12 with a natural menstrual cycle, 10 taking a high-androgenicity oral contraceptive and 8 taking a low-androgenicity oral contraceptive), aged 18 to 30 years, were tested three times throughout one menstrual or oral contraceptive cycle. Counter-movement jumps, bilateral hop jumps, handgrip strength, isometric knee extensor strength and isokinetic knee flexion and extension were assessed. Perceptual ratings of fatigue, muscle soreness, pain and mood were recorded. Most variables showed no significant changes over the menstrual or oral contraceptive cycle. However, for the menstrual cycle group, isokinetic knee flexion at 240° s−1, and time of flight in bilateral hopping and counter movement jumps showed better results during the mid-luteal phase compared with the late follicular phase. For the high-androgenicity oral contraceptive group, isokinetic knee flexion at 240° s−1 was significantly higher in the late hormone phase compared with the early hormone phase. For the low-androgenicity oral contraceptive group, time of flight for the counter-movement jumps was lower in the late hormone phase compared with the early hormone phase. The findings indicate that faster and explosive aspects of muscle performance may be influenced by endogenous and exogenous female hormones.

Abstract
Direct oral anticoagulants (DOACs) are replacing warfarin and other vitamin K antagonists for a wide range of indications. Advantages of DOAC therapy are fewer food and drug interactions and fixed dosing without routine laboratory monitoring, making DOACs the perfect choice especially for younger patients, in whom the main indication for anticoagulation is prevention and treatment of venous thromboembolism (VTE). Although DOACs are safer and much more convenient than other anticoagulant alternatives, their profile may have drawbacks, especially for younger female patients in whom reproductive issues need special considerations. These may include the issue of heavy menstrual bleeding (HMB) during anticoagulant therapy, the embryotoxicity risk from inadvertent DOAC exposure during pregnancy, and the prevention or planning of pregnancies during DOAC therapy. This review summarizes the most relevant evidence in this increasingly important field of women's health.

Abstract
Abstract
Purpose of review
Cardiovascular disease (CVD) is the number one cause of maternal mortality in the USA. There are many cardiac conditions which pose significant risk to maternal health, and these women should be offered options to avoid unwanted pregnancies. Individualized contraceptive counseling focusing on woman’s desire for future pregnancy, comorbid conditions, and desire for hormone or non-hormonal (contraceptive) options is paramount to avoid adverse or unwanted side effects. The purpose of this review is to give general guidance on prescribing both hormonal and non-hormonal contraceptives for providers caring for women with heart disease.
Recent findings
Specific recommendation for the use of either non-hormonal or hormonal contraception requires knowledge of the types of contraceptive options available, cost, failure rates, and contraindications to use. Newer progestin-only options have become available and should be considered first-line therapy for women with cardiovascular disease.
Summary
The physiologic burden of pregnancy on the cardiovascular system can cause significant maternal morbidity and mortality for women with underlying CVD. These women should be offered safe and effective options for birth control, and both cardiology and obstetrical providers alike should possess fundamental knowledge of appropriate options.

Abstract
Combined oral contraceptives (COCs) are commonly prescribed and increase the risk of venous thromboembolism (VTE). We have previously found that two COCs, both containing drospirenone (DRSP) and ethinyl estradiol (EE), cause spontaneous fibrin formation in whole blood. The aim of this study was, therefore, to use platelet-poor plasma (PPP) from the same cohort of DRSP/EE users to determine the impact of these COCs on the fibrin component, specifically the fibrin clot viscoelasticity, turbidimetry, and biophysical traits. PPP from 25 females per test group and a control group (n = 25) were analyzed using thromboelastography (TEG), turbidimetry, and scanning electron microscopy. The results highlight abnormal fibrin clot formation, lysis, and architecture; DRSP/20EE showed the greatest effect. DRSP/EE use increased the fibrin fiber diameter and showed dense matted clots. Only when the influence of COCs on the structural properties and behavior of fibrin fibers during thrombus formation and lysis is better understood are we able to predict and prevent coagulopathies associated with these synthetic hormones. Clinical practitioners should take this into consideration for female patients that either have comorbidities, which could burden the coagulation system, or may be exposed to external factors that could increase their risk for VTE.

Abstract
OBJECTIVES Female genital mutilation (FGM) includes procedures that remove partial or total external female genitalia, or causes other injury to female genital organs with no medical reason. Physical and psychological trauma associated with FGM may interfere with a woman's ability and intent to utilize contraception. Our study examines the association between FGM and utilization of contraception methods among sexually active reproductive-aged women in Egypt. METHODS Data from the 2014 Egypt Demographic and Health Survey were analyzed (n = 20,055). Multinomial logistic regression was used to obtain odds ratios (OR) and 95% confidence intervals. RESULTS Our study found that FGM was performed on over 90% of Egyptian women and almost half (45%) of women did not use contraception. Women with FGM had significantly lower odds (OR = 0.6) of using barrier/natural contraceptive methods (e.g., condoms) than intrauterine devices (IUDs). However, women with FGM were more likely to use hormonal methods (OR = 1.2) than IUDs compared to those who had not experienced FGM. CONCLUSIONS In order to promote women's health and support use of effective contraception methods, a large reduction in FGM practice is essential.

Hartnett Y, Drakeford C, Dunne L, McLoughlin DM, Kennedy N. Physician, heal thyself: a cross-sectional survey of doctors' personal prescribing habits. JOURNAL OF MEDICAL ETHICS 2020; 46:231-235. [PMID: 31796545 DOI: 10.1136/medethics-2018-105064] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2018] [Revised: 08/26/2019] [Accepted: 10/17/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND Self-prescribing and prescribing to personal contacts is explicitly discouraged by General Medical Council guidelines. AIMS This study examines how widespread the practice of self-prescribing and prescribing to personal contacts is. METHODS A 16-item questionnaire was distributed via an online forum comprising 4445 young medical doctors (representing 20% of all Irish registered doctors), which asked respondents about previous prescribing to themselves, their families, friends and colleagues, including the class of medication prescribed. Demographic details were collected including medical grade and specialty. RESULTS A total of 729 responses were obtained, the majority of which were from young non-consultant hospital doctors from a range of specialties. Two-thirds of respondents had self-prescribed, over 70% had prescribed to family, and nearly 60% had prescribed to a friend or colleague. Older doctors were more likely to self-prescribe (χ2=17.51, p<0.001). Interns being less likely to self-prescribe was not unexpected (χ2=69.55, p<0.001), while general practitioners (GPs) and paediatricians were more likely to self-prescribe (χ2=13.33, p<0.001; χ2=11.35, p<0.001). GPs, paediatricians and hospital medicine specialties were more likely to prescribe to family (χ2=5.19, p<0.05; χ2=8.38, p<0.05; χ2=6.17, p<0.05) and surgeons were more likely to prescribe to friends (χ2=15.87, p<0.001). Some 3% to 7% who had self-prescribed had prescribed an opiate, benzodiazepine or psychotropic medication. Male doctors, anaesthetists and surgeons were more likely to self-prescribe opioids (χ2=7.82, p<0.01; χ2=7.31, p<0.01; χ2=4.91, p<0.05), while those in hospital medicine were more likely to self-prescribe psychotropic medications (χ2=5.47, p<0.05). CONCLUSION Prescribing outside the traditional doctor-patient relationship is widespread despite clear professional guidance advising against it.

Abstract
Dysmenorrhea often significantly reduces the quality of women's life and is still an important public health problem. Despite numerous studies, the pathomechanism of dysmenorrhea is not fully understood. Previous research indicates the complexity of biochemical reactions between the endocrine, vascular, and immune systems. Prostaglandins play a major role in the pathomechanism of dysmenorrhea. In contrast, cytokines and other proinflammatory factors in primary dysmenorrhea are less studied. In addition to the applied pharmacotherapy, more and more studies proving the effectiveness of non-pharmacological methods appear. Therefore, the present work contains a review of the latest research concerning factors involved in dysmenorrhea, as well as therapeutic options. In the literature search, authors used online databases, PubMed, and clinitrials.gov and browsed through individual gynecology, physiotherapy journals and books.

Abstract
BACKGROUND Resistance training is well known to increase strength and lean body mass, and plays a key role in many female athletic and recreational training programs. Most females train throughout their reproductive years when they are exposed to continuously changing female steroid hormone profiles due to the menstrual cycle or contraceptive use. Therefore, it is important to focus on how female hormones may affect resistance training responses. OBJECTIVE The aim of this systematic review is to identify and critically appraise current studies on the effect of the menstrual cycle and oral contraceptives on responses to resistance training. METHODS The electronic databases Embase, PubMed, SPORTDiscus and Web of Science were searched using a comprehensive list of relevant terms. Studies that investigated the effect of the menstrual cycle phase or oral contraceptive cycle on resistance training responses were included. Studies were also included if they compared resistance training responses between the natural menstrual cycle and oral contraceptive use, or if resistance training was adapted to the menstrual cycle phase or oral contraceptive phase. Studies were critically appraised with the McMasters Universities Critical Review Form for Quantitative Studies and relevant data were extracted. RESULTS Of 2007 articles found, 17 studies met the criteria and were included in this systematic review. The 17 included studies had a total of 418 participants with an age range of 18-38 years. One of the 17 studies found no significant differences in acute responses to a resistance training session over the natural menstrual cycle, while four studies did find changes. When assessing the differences in acute responses between the oral contraceptive and menstrual cycle groups, two studies reported oral contraceptives to have a positive influence, whilst four studies reported that oral contraceptive users had a delayed recovery, higher levels of markers of muscle damage, or both. For the responses to a resistance training program, three studies reported follicular phase-based training to be superior to luteal phase-based training or regular training, while one study reported no differences. In addition, one study reported no differences in strength development between oral contraceptive and menstrual cycle groups. One further study reported a greater increase in type I muscle fibre area and a trend toward a greater increase in muscle mass within low-androgenic oral contraceptive users compared with participants not taking hormonal contraceptives. Finally, one study investigated androgenicity of oral contraceptives and showed greater strength developments with high androgenic compared with anti-androgenic oral contraceptive use. CONCLUSIONS The reviewed articles reported conflicting findings, and were often limited by small participant numbers and methodological issues, but do appear to suggest female hormones may affect resistance training responses. The findings of this review highlight the need for further experimental studies on the effects of the menstrual cycle and oral contraceptives on acute and chronic responses to resistance training.

Abstract
Background:The combined oral contraceptive pill (OC), containing synthetic estrogens and progestins, is used by millions of women worldwide, yet little is known about its effects on cognition or on psychiatric disorders. The progestin component of OCs determines their androgenicity, i.e. whether the OC has androgen binding components with masculinising effects or antiandrogenic components with feminising effects.Objective:The present review discusses the literature surrounding OC use and cognition in healthy women. Given the important role that sex hormones play in psychiatric disorders, we also consider the influence of OCs on symptoms of schizophrenia, post-traumatic stress disorder, depression, bipolar disorder, anxiety disorders and indirectly, sleep quality.Results:Research has shown that while there are no differences between OC users and non-users, androgenic OCs enhance visuospatial ability and anti-androgenic OCs enhance verbal fluency. Little is known about OCs effects on other cognitive domains, such as memory and executive function. There is little research examining OC use in schizophrenia, post-traumatic stress disorder, bipolar disorder and anxiety disorders. There is some evidence that OC use is associated with depression, however the exact causality of this association remains to be verified.Conclusion:We maintain that future studies need to address several methodological limitations, such as separating OCs based on androgenicity to avoid the masking effects that occur when various OCs are considered as one group. As this review highlights several significant effects of OC use on the brain, the implications of OC use needs to be considered in future research.

Abstract
Sexual and reproductive health are an integral part of all youths' health and wellbeing, including youth who are transgender and gender-expansive. This article will discuss general approaches to the sexual and reproductive health care of transgender and gender-expansive youth, and review the topics of contraception and menstrual suppression, fertility preservation and family building, and the prevention and treatment of sexually transmitted infections and HIV in this population. Although transgender youth on testosterone therapy often become amenorrheic, ovulation and pregnancy can still occur, and thus all youth on testosterone therapy should be counseled on the potential for pregnancy and have access to effective contraception. Many forms of hormonal contraceptives are both safe and efficacious when used by youth on testosterone therapy. Hormonal contraceptives may also be used to provide menstrual suppression for those experiencing dysphoria from unwanted uterine bleeding. All transgender youth should receive counseling on fertility preservation and reproductive options prior to starting pubertal blockers and/or gender-affirming hormones, therapies that have varying effects on long-term fertility potential. Several different methods of fertility preservation exist, however there are numerous barriers to transgender youth receiving fertility preservation services, and rates of utilization of these services is low. Transgender individuals suffer from a disproportionate burden of HIV compared to their peers-thought to result from stigma, marginalization, and lack of access to appropriate care. All providers caring for youth should be informed about HIV pre-exposure prophylaxis (PrEP) and HIV post-exposure prophylaxis (PEP), which may help to prevent HIV acquisition.

Abstract
Objective To evaluate the effectiveness of oral contraceptive pill (OCP) as therapy for endometrial hyperplasia (EH) without atypia in reproductive-aged women compared with oral progestin. Methods A retrospective cohort study was carried out in our reproductive center. Consecutive patients diagnosed with infertility and non-atypical EH identified through electronic database who met inclusion criteria (n=309). Patients were assigned to two treatment groups: OCP (n=216) and oral progestin (n=93); clinical and reproductive outcomes were recorded. Results Reversal of EH to normal endometrium, clinical pregnancy, live birth and miscarriage rate. Women in OCP group were younger, had higher prevalence of Polycystic Ovary Syndrome and other uterine pathology and longer duration of infertility than women in progestin group. Reversal of EH was observed in 93.52% women on OCP and in 86.02% women on progestin (p=0.032; adjusted odds ratio [aOR]= 2.35; 95% confidence interval [CI]=1.06-5.21) after the initial course of treatment for 2 to 6 months. Cyclic OCP (n=184) resulted in better response to treatment compared to continuous OCP (n=32) (95.11% vs. 84.38%; p=0.039; aOR =3.60; 95% CI =1.12-11.55). Clinical pregnancy rate in OCP group was marginally higher than progestin group (87/208, 41.83% vs. 27/90, 30.00%; p=0.054). Miscarriage (25.29% vs. 29.63%; p=0.654) and live birth rate (31.25% vs. 21.11%; p=0.074) were comparable between the groups. Conclusion For the first time we demonstrate that OCP is an effective therapy for non-atypical EH and is associated with higher remission rate compared with oral progestin. Reproductive outcomes are reassuring and comparable between the two groups.

Abstract
This study aimed at evaluating the availability of the primate Sapajus libidinosus as an animal model for research assessing the physiological effects of the continuous use of combined hormonal contraceptives. In order to do this, six reproductively active female S. libidinosus from the Primate Research Center of the University of Brasília were selected to take part in this experiment. Every 21 days or so, each female received a single dose of combined hormonal contraceptive (algestone acetophenide and 17-enanthate estradiol) in a total of five doses throughout the experiment. The physiological parameters were accessed by means of 13 blood samples from each female, whereas three were gathered during the baseline and 10 samples were collected during the treatment phase. The results showed that the contraceptive use provoked changes in hematological coagulation factors such as an increase in the amount of platelets (p = 0.039) and a reduction in both prothrombin (p < 0.001) and thromboplastin coagulation time (p < 0.001). These results are similar to what has been observed in human patients; thus, it is concluded that S. libidinosus can be successfully used in studies about the physiological impact of hormonal contraceptives.

Abstract
OBJECTIVES Primary dysmenorrhoea is a common complaint experienced by many females in their reproductive years. The use of medicinal plants in the treatment of various gynaecological conditions is on the increase, despite the limited evidence available regarding efficacy and safety of their use. The aim of this systematic review was to synthesise the most recent evidence relating to the treatment of primary dysmenorrhoea with medicinal plants. METHODOLOGY A thorough database search was conducted using defined search terms, and randomised controlled trials (RCTs) published in English between 2008 and 2016, pertaining to the use of medicinal plants (single use) for the treatment of primary dysmenorrhoea, were assessed. Studies evaluating dysmenorrhoeal pain and associated symptoms as a primary or secondary outcome were considered and assessed by two reviewers independently of each other, using the JADAD scale and the Cochrane risk of bias tool,. RESULTS 22 RCTs were included in the review; 9 were placebo-controlled trials and 13 were comparative studies to pharmacological treatment or nutritional supplements. Most of the evaluated medicinal plants showed evidence of efficacy in relieving menstrual pain in at least one RCT. The low or unclear quality of the majority of these studies however warrants caution in interpreting these results. CONCLUSION This review adds to the knowledge-base on the use of these medicinal plants in the treatment of primary dysmenorrhoea. Further research is needed before definitive conclusions can be made regarding the efficacy and safety of the use of these medicinal plants.

Abstract
UNLABELLED In the present retrospective case-control study, we compared 6485 women with fractures and 6485 women without fractures from 135 general practitioner offices in the UK. Women without bone fractures were statistically more likely to have been exposed to oral contraception, depending on their age and therapy duration. INTRODUCTION The aim of this analysis was to compare the risk of bone fracture in women using hormonal contraception with that in women who have never used hormonal contraception. METHODS A total of 6485 women (mean age 37.8 years) with an initial diagnosis of fracture between January 2010 and December 2015 were identified in 135 doctors' offices in the UK Disease Analyzer database. In this nested case-control study, each case with a fracture was matched (1:1) to a control without a fracture for age, index year, and follow-up time. In total, 12,970 individuals were available for analysis. The main outcome of the study was the risk of fracture as a function of combined oral contraceptive (OC) therapy. Multivariate logistic regression models were used to determine the effect of OC therapy and its duration on the risk of fracture in the entire population and in four age-specific subgroups. RESULTS Women without bone fractures were significantly more likely to have used oral contraception (OR 0.81). The usage of oral contraception was associated with a significantly lower risk of bone fracture (OR 0.81, 95% CI 0.74-0.90). This effect was strongest in the age groups 18-25 and 26-35 and in patients with an OC treatment duration of more than 1 year. CONCLUSIONS The present study revealed that women without bone fractures were significantly more likely to have had exposure to combined oral contraception, especially where the duration of intake was at least 5 years.

Abstract
STUDY OBJECTIVE To evaluate the efficacy of continuous norethisterone acetate (NET-A), 5 mg (group N) vs cyclical combined oral contraceptive pill (COC) consisting of drospirenone 3 mg/ethinyl estradiol 20 μg pills (group P) in treating dysmenorrhea in young adult women. DESIGN, SETTING, AND PARTICIPANTS This prospective, open-label, nonrandomized study included 38 Jordanian patients: 20 patients in group N and 18 patients in group P. INTERVENTIONS Continuous NET-A 5 mg daily or cyclical COC. MAIN OUTCOME MEASURES Pain scores, adverse effects, analgesic use, school absence, and cost. RESULTS Thirty-eight patients used NET-A or COC for 6 months. All participants had almost the same starting levels of visual analogue scale (VAS) scores. Both drugs were similar in suppressing dysmenorrhea at the 3-month follow-up visit; VAS score mean (±SD) in group N and P were 1.30 ± 1.22 and 1.28 ± 0.83 (P = .22), respectively, and after 6 months, with mean VAS scores (±SD) of 1.30 ± 1.22 and 1.28 ± 0.83, respectively (P = .95). The cost of the treatment in the N group was much less than in the P group. Participants in the N group were less likely to use pain killers: 20% and 44% in the N and P groups, respectively (P = .006) in the first month and only 5% and 17% (P = .019) in the N and P groups, respectively, at the 3-month follow-up, and none of them used any analgesics at the 6-month follow-up. CONCLUSION A continuous NET-A regimen is a well tolerated, effective, and inexpensive option for dysmenorrhea treatment and was as good as COC.

Abstract
BACKGROUND Heavy menstrual bleeding significantly impairs the quality of life of many otherwise healthy women. Perception of heavy menstrual bleeding is subjective and management usually depends upon what symptoms are acceptable to the individual. Surgical options include conservative surgery (uterine resection or ablation) and hysterectomy. Medical treatment options include oral medication and a hormone-releasing intrauterine device (LNG-IUS). OBJECTIVES To compare the effectiveness, safety and acceptability of surgery versus medical therapy for heavy menstrual bleeding. SEARCH METHODS We searched the following databases from inception to January 2016: Cochrane Gynaecology and Fertility Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO and clinical trials registers (clinical trials.gov and ICTRP). We also searched the reference lists of retrieved articles. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing conservative surgery or hysterectomy versus medical therapy (oral or intrauterine) for heavy menstrual bleeding. DATA COLLECTION AND ANALYSIS Two review authors independently selected the studies, assessed their risk of bias and extracted the data. Our primary outcomes were menstrual bleeding, satisfaction rate and adverse events. Where appropriate we pooled the data to calculate pooled risk ratios (RRs) or mean differences, with 95% confidence intervals (CIs), using a fixed-effect model. We assessed heterogeneity with the I(2) statistic and evaluated the quality of the evidence using GRADE methods. MAIN RESULTS We included 15 parallel-group RCTs (1289 women). Surgical interventions included hysterectomy and endometrial resection or ablation. Medical interventions included oral medication and the levonorgestrel-releasing intrauterine device (LNG-IUS). The overall quality of the evidence for different comparisons ranged from very low to moderate. The main limitations were lack of blinding, attrition and imprecision. Moreover, it was difficult to interpret long-term study findings as many women randomised to medical interventions subsequently underwent surgery. Surgery versus oral medicationSurgery (endometrial resection) was more effective in controlling bleeding at four months (RR 2.66, 95% CI 1.94 to 3.64, one RCT, 186 women, moderate quality evidence) and also at two years (RR 1.29, 95% CI 1.06 to 1.57, one RCT, 173 women, low quality evidence). There was no evidence of a difference between the groups at five years (RR 1.14, 95% CI 0.97 to 1.34, one RCT, 140 women, very low quality evidence).Satisfaction with treatment was higher in the surgical group at two years (RR 1.40, 95% CI 1.13 to 1.74, one RCT, 173 women, moderate quality evidence), but there was no evidence of a difference between the groups at five years (RR 1.13, 95% CI 0.94 to 1.37, one RCT, 114 women, very low quality evidence). There were fewer adverse events in the surgical group at four months (RR 0.26, 95 CI 0.15 to 0.46, one RCT, 186 women). These findings require cautious interpretation, as 59% of women randomised to the oral medication group had had surgery within two years and 77% within five years. Surgery versus LNG-IUSWhen hysterectomy was compared with LNG-IUS, the hysterectomy group were more likely to have objective control of bleeding at one year (RR 1.11, 95% CI 1.05 to 1.19, one RCT, 223 women, moderate quality evidence). There was no evidence of a difference in quality of life between the groups at five or 10 years, but by 10 years 46% of women originally assigned to LNG-IUS had undergone hysterectomy. Adverse effects associated with hysterectomy included surgical complications such as bladder or bowel perforation and vesicovaginal fistula. Adverse effects associated with LNG-IUS were ongoing bleeding and hormonal symptoms.When conservative surgery was compared with LNG-IUS, at one year the surgical group were more likely to have subjective control of bleeding (RR 1.19, 95% CI 1.07 to 1.32, five RCTs, 281 women, low quality evidence, I(2) = 15%). Satisfaction rates were higher in the surgical group at one year (RR 1.16, 95% CI 1.04, to 1.28, six RCTs, 442 women, I(2) = 27%), but this finding was sensitive to the choice of statistical model and use of a random-effects model showed no conclusive evidence of a difference between the groups. There was no evidence of a difference between the groups in satisfaction rates at two years (RR 0.93, 95% CI 0.81 to 1.08, two RCTs, 117 women, I(2) = 1%).At one year there were fewer adverse events (such as bleeding and spotting) in the surgical group (RR 0.36, 95% CI 0.15 to 0.82, three RCTs, moderate quality evidence). It was unclear what proportion of women assigned to LNG-IUS underwent surgery over long-term follow-up, as there were few data beyond one year. AUTHORS' CONCLUSIONS Surgery, especially hysterectomy, reduces menstrual bleeding more than medical treatment at one year. There is no conclusive evidence of a difference in satisfaction rates between surgery and LNG-IUS, though adverse effects such as bleeding and spotting are more likely to occur with LNG-IUS. Oral medication suits a minority of women in the long term, and the LNG-IUS device provides a better alternative to surgery in most cases. Although hysterectomy is a definitive treatment for heavy menstrual bleeding, it can cause serious complications for a minority of women. Most women may be well advised to try a less radical treatment as first-line therapy. Both LNG-IUS and conservative surgery appear to be safe, acceptable and effective.

Abstract
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 contraceptives are at least patient convenient, efficacious, and safe for the treatment of PCOS. However, well-designed, prospective, long-term, large-scale, randomized clinical trials are necessary to elucidate the efficacy and safety of metformin, oral contraceptives, or both in the treatment of PCOS, and to elucidate their individual roles in the treatment of this condition.

Abstract
BACKGROUND Breast density is a strong risk factor for breast cancer and reflects epithelial and stromal content. Breast tissue is particularly sensitive to hormonal stimuli before it fully differentiates following the first full-term pregnancy. Few studies have examined associations between sex hormones and breast density among young women. METHODS We conducted a cross-sectional study among 180 women ages 25 to 29 years old who participated in the Dietary Intervention Study in Children 2006 Follow-up Study. Eighty-five percent of participants attended a clinic visit during their luteal phase of menstrual cycle. Magnetic resonance imaging measured the percentage of dense breast volume (%DBV), absolute dense breast volume (ADBV), and absolute nondense breast volume (ANDBV). Multiple-linear mixed-effect regression models were used to evaluate the association of sex hormones and sex hormone-binding globulin (SHBG) with %DBV, ADBV, and ANDBV. RESULTS Testosterone was significantly positively associated with %DBV and ADBV. The multivariable geometric mean of %DBV and ADBV across testosterone quartiles increased from 16.5% to 20.3% and from 68.6 to 82.3 cm(3), respectively (Ptrend ≤ 0.03). There was no association of %DBV or ADBV with estrogens, progesterone, non-SHBG-bound testosterone, or SHBG (Ptrend ≥ 0.27). Neither sex hormones nor SHBG was associated with ANDBV except progesterone; however, the progesterone result was nonsignificant in analysis restricted to women in the luteal phase. CONCLUSIONS These findings suggest a modest positive association between testosterone and breast density in young women. IMPACT Hormonal influences at critical periods may contribute to morphologic differences in the breast associated with breast cancer risk later in life.
