Review
Over the past decade, women in Western countries have taken to various social media platforms to share their dissatisfactory experiences with hormonal contraception, which may be pills, patches, rings, injectables, implants or hormonal intrauterine devices (IUDs). These online testimonials have been denounced as spreading "hormonophobia", i.e. an excessive fear of hormones based on irrational causes such as an overestimation of health risks associated with their use, that was already aroused by the recurring media controversies over hormonal contraception. In order to move toward a reproductive justice framework, we propose to study the arguments that women and men (as partners of female users) recently put forward against hormonal contraception to see whether they are related to hormonophobia. The aim of this article is to conduct a systematic review of the recent scientific literature in order to construct an evidence-based typology of reasons for rejecting hormonal contraception, in a continuum perspective from complaints to choosing not to use it, cited by women and men in Western countries in a recent time. The published literature was systematically searched using PubMed and the database from the French National Institute for Demographic Studies (Ined). A total of 42 articles were included for full-text analysis. Eight main categories emerged as reasons for rejecting hormonal contraception: problems related to physical side effects; altered mental health; negative impact on sexuality; concerns about future fertility; invocation of nature; concerns about menstruation; fears and anxiety; and the delegitimization of the side effects of hormonal contraceptives. Thus, arguments against hormonal contraception appeared complex and multifactorial. Future research should examine the provider-patient relationship, the gender bias of hormonal contraception and demands for naturalness in order to understand how birth control could better meet the needs and expectations of women and men in Western countries today.

Meta-Analysis Review
BACKGROUND
Dysmenorrhoea is a common gynaecological problem consisting of painful cramps accompanying menstruation, which in the absence of any underlying abnormality is known as primary dysmenorrhoea. Research has shown that women with dysmenorrhoea have high levels of prostaglandins, hormones known to cause cramping abdominal pain. Nonsteroidal anti-inflammatory drugs (NSAIDs) are drugs that act by blocking prostaglandin production. They inhibit the action of cyclooxygenase (COX), an enzyme responsible for the formation of prostaglandins. The COX enzyme exists in two forms, COX-1 and COX-2. Traditional NSAIDs are considered 'non-selective' because they inhibit both COX-1 and COX-2 enzymes. More selective NSAIDs that solely target COX-2 enzymes (COX-2-specific inhibitors) were launched in 1999 with the aim of reducing side effects commonly reported in association with NSAIDs, such as indigestion, headaches and drowsiness.
OBJECTIVES
To determine the effectiveness and safety of NSAIDs in the treatment of primary dysmenorrhoea.
SEARCH METHODS
We searched the following databases in January 2015: Cochrane Menstrual Disorders and Subfertility Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, November 2014 issue), MEDLINE, EMBASE and Web of Science. We also searched clinical trials registers (ClinicalTrials.gov and ICTRP). We checked the abstracts of major scientific meetings and the reference lists of relevant articles.
SELECTION CRITERIA
All randomised controlled trial (RCT) comparisons of NSAIDs versus placebo, other NSAIDs or paracetamol, when used to treat primary dysmenorrhoea.
DATA COLLECTION AND ANALYSIS
Two review authors independently selected the studies, assessed their risk of bias and extracted data, calculating odds ratios (ORs) for dichotomous outcomes and mean differences for continuous outcomes, with 95% confidence intervals (CIs). We used inverse variance methods to combine data. We assessed the overall quality of the evidence using GRADE methods.
MAIN RESULTS
We included 80 randomised controlled trials (5820 women). They compared 20 different NSAIDs (18 non-selective and two COX-2-specific) versus placebo, paracetamol or each other. NSAIDs versus placeboAmong women with primary dysmenorrhoea, NSAIDs were more effective for pain relief than placebo (OR 4.37, 95% CI 3.76 to 5.09; 35 RCTs, I(2) = 53%, low quality evidence). This suggests that if 18% of women taking placebo achieve moderate or excellent pain relief, between 45% and 53% taking NSAIDs will do so.However, NSAIDs were associated with more adverse effects (overall adverse effects: OR 1.29, 95% CI 1.11 to 1.51, 25 RCTs, I(2) = 0%, low quality evidence; gastrointestinal adverse effects: OR 1.58, 95% CI 1.12 to 2.23, 14 RCTs, I(2) = 30%; neurological adverse effects: OR 2.74, 95% CI 1.66 to 4.53, seven RCTs, I(2) = 0%, low quality evidence). The evidence suggests that if 10% of women taking placebo experience side effects, between 11% and 14% of women taking NSAIDs will do so. NSAIDs versus other NSAIDsWhen NSAIDs were compared with each other there was little evidence of the superiority of any individual NSAID for either pain relief or safety. However, the available evidence had little power to detect such differences, as most individual comparisons were based on very few small trials. Non-selective NSAIDs versus COX-2-specific selectorsOnly two of the included studies utilised COX-2-specific inhibitors (etoricoxib and celecoxib). There was no evidence that COX-2-specific inhibitors were more effective or tolerable for the treatment of dysmenorrhoea than traditional NSAIDs; however data were very scanty. NSAIDs versus paracetamolNSAIDs appeared to be more effective for pain relief than paracetamol (OR 1.89, 95% CI 1.05 to 3.43, three RCTs, I(2) = 0%, low quality evidence). There was no evidence of a difference with regard to adverse effects, though data were very scanty.Most of the studies were commercially funded (59%); a further 31% failed to state their source of funding.
AUTHORS' CONCLUSIONS
NSAIDs appear to be a very effective treatment for dysmenorrhoea, though women using them need to be aware of the substantial risk of adverse effects. There is insufficient evidence to determine which (if any) individual NSAID is the safest and most effective for the treatment of dysmenorrhoea. We rated the quality of the evidence as low for most comparisons, mainly due to poor reporting of study methods.

Meta-Analysis
BACKGROUND
Girls and women need effective, safe, and affordable menstrual products. Single-use products are regularly selected by agencies for resource-poor settings; the menstrual cup is a less known alternative. We reviewed international studies on menstrual cup leakage, acceptability, and safety and explored menstrual cup availability to inform programmes.
METHODS
In this systematic review and meta-analysis, we searched PubMed, Cochrane Library, Web of Science, Popline, Cinahl, Global Health database, Emerald, Google Scholar, Science.gov, and WorldWideScience from database inception to May 14, 2019, for quantitative or qualitative studies published in English on experiences and leakage associated with menstrual cups, and adverse event reports. We also screened the Manufacturer and User Facility Device Experience database from the US Food and Drug Administration for events related to menstrual cups. To be eligible for inclusion, the material needed to have information on leakage, acceptability, or safety of menstrual cups. The main outcome of interest was menstrual blood leakage when using a menstrual cup. Safety outcomes of interest included serious adverse events; vaginal abrasions and effects on vaginal microflora; effects on the reproductive, digestive, or urinary tract; and safety in poor sanitary conditions. Findings were tabulated or combined by use of forest plots (random-effects meta-analysis). We also did preliminary estimates on costs and environmental savings potentially associated with cups. This systematic review is registered on PROSPERO, number CRD42016047845.
FINDINGS
Of 436 records identified, 43 studies were eligible for analysis (3319 participants). Most studies reported on vaginal cups (27 [63%] vaginal cups, five [12%] cervical cups, and 11 [25%] mixed types of cups or unknown) and 15 were from low-income and middle-income countries. 22 studies were included in qualitative or quantitative syntheses, of which only three were of moderate-to-high quality. Four studies made a direct comparison between menstrual cups and usual products for the main outcome of leakage and reported leakage was similar or lower for menstrual cups than for disposable pads or tampons (n=293). In all qualitative studies, the adoption of the menstrual cup required a familiarisation phase over several menstrual cycles and peer support improved uptake (two studies in developing countries). In 13 studies, 73% (pooled estimate: n=1144; 95% CI 59-84, I=96%) of participants wished to continue use of the menstrual cup at study completion. Use of the menstrual cup showed no adverse effects on the vaginal flora (four studies, 507 women). We identified five women who reported severe pain or vaginal wounds, six reports of allergies or rashes, nine of urinary tract complaints (three with hydronephrosis), and five of toxic shock syndrome after use of the menstrual cup. Dislodgement of an intrauterine device was reported in 13 women who used the menstrual cup (eight in case reports, and five in one study) between 1 week and 13 months of insertion of the intrauterine device. Professional assistance to aid removal of menstrual cup was reported among 47 cervical cup users and two vaginal cup users. We identified 199 brands of menstrual cup, and availability in 99 countries with prices ranging US$0·72-46·72 (median $23·3, 145 brands).
INTERPRETATION
Our review indicates that menstrual cups are a safe option for menstruation management and are being used internationally. Good quality studies in this field are needed. Further studies are needed on cost-effectiveness and environmental effect comparing different menstrual products.

Meta-Analysis
IMPORTANCE
The initial clinical sign of pubertal onset in girls is breast gland development (thelarche). Although numerous studies have used recalled age at menarche (first menstruation) to assess secular trends of pubertal timing, no systematic review has been conducted of secular trends of thelarche.
OBJECTIVES
To systematically evaluate published data on pubertal timing based on age at thelarche and evaluate the change in pubertal onset in healthy girls around the world.
DATA SOURCES
A systematic literature search was performed in PubMed and Embase of all original peer-reviewed articles published in English before June 20, 2019.
STUDY SELECTION
Included studies used clinical assessment of breast development in healthy girls and used adequate statistical methods, including the reporting of SEs or CIs. The quality of the articles was evaluated by assessing study design, potential sources of bias, main characteristics of the study population, and methods of statistical analysis.
DATA EXTRACTION AND SYNTHESIS
In accordance with PRISMA guidelines, all articles were assessed for eligibility independently by 2 authors. Weighted regression analysis was performed using a random-effects model.
MAIN OUTCOMES AND MEASURES
Studies examining age at thelarche (development of Tanner breast stage 2) in healthy girls.
RESULTS
The literature search resulted in a total of 3602 studies, of which 30 studies fulfilled the eligibility criteria. There was a secular trend in ages at thelarche according to race/ethnicity and geography. Overall, the age at thelarche decreased 0.24 years (95% CI, -0.44 to -0.04) (almost 3 months) per decade from 1977 to 2013 (P = .02).
CONCLUSIONS AND RELEVANCE
The age at thelarche has decreased a mean of almost 3 months per decade from 1977 to 2013. A younger age at pubertal onset may change current diagnostic decision-making. The medical community needs current and relevant data to redefine "precocious puberty," because the traditional definition may be outdated, at least in some regions of the world.

Meta-Analysis
BACKGROUND
The need to control for the potential influence of menstrual cycle phase on resting metabolism (RMR) places a burden on research participants who must self-report onset of menstruation and researchers who must schedule metabolic testing accordingly.
PURPOSE
To systematically review and analyze existing research to determine the effect of menstrual cycle on RMR.
METHODS
We searched PubMed, CINAHL, MEDLINE, SPORTDiscus, and Scopus databases using the search terms "menstrual cycle and metabolic rate" and "menstrual cycle and energy expenditure." Eligibility criteria were English language, single-group repeated measures design, and RMR as either a primary or secondary outcome. Risk of bias was assessed based on study sample, measurement, and control of confounders. Differences between the follicular and luteal phases of the menstrual cycle were analyzed using the standardized mean difference in effect size.
RESULTS
Thirty English-language studies published between 1930 and December 2019 were included in the systematic review, and 26 studies involving 318 women were included in the meta-analysis. Overall, there was a small but significant effect favoring increased RMR in the luteal phase (ES = 0.33; 95% CI = 0.17, 0.49, p < 0.001).
DISCUSSION
Limitations include risk of bias regarding measurement of both menstrual cycle and RMR. Sample sizes were small and studies did not report control of potential confounders. Sub-group analysis demonstrated that in more recent studies published since 2000, the effect of menstrual phase was reduced and not statistically significant (ES = 0.23; 95% CI = -0.00, 0.47; p = 0.055). Until larger and better designed studies are available, based on our current findings, researchers should be aware of the potential confounding influence of the menstrual cycle and control for it by testing consistently in one phase of the cycle when measuring RMR in pre-menopausal women.

BACKGROUND
Menopause is the time that marks passing 12 months after the last menstruation cycle in women between ages 40-50. Menopausal women often experience depression and insomnia that significantly impact their overall well-being and quality of life. This systematic review aims to determine the effects of different therapeutic physiotherapy modalities on insomnia and depression in perimenopausal, menopausal, and post-menopausal women.
METHODOLOGY
After identifying our inclusion/exclusion criteria, we conducted a database search in Ovid Embase, MIDRIS, PubMed, Cochrane, and ScienceOpen, where 4007 papers were identified. By using EndNote software, we excluded duplicates, unrelated, and non-full text papers. Adding more studies from manual search, we finally included 31 papers including 7 physiotherapy modalities: exercise, reflexology, footbath, walking, therapeutic and aromatherapy massage, craniofacial message, and yoga.
RESULTS
Reflexology, yoga, walking and aromatherapy massage showed an overall significant impact on decreasing insomnia and depression in menopausal women. Most of exercise and stretching interventions also showed improvement in sleep quality but inconsistent findings regarding depression. However, insufficient evidence was found regarding the effect of craniofacial massage, footbath, and acupressure on improving sleep quality and depression in menopausal women.
CONCLUSION
Using non-pharmaceutical interventions such as therapeutic and manual physiotherapy have an overall positive impact on reducing insomnia and depression in menopausal women.

Review
Finasteride and dutasteride, both 5-alpha reductase inhibitors, are considered first-line treatment for androgenetic hair loss in men and used increasingly in women. In each case, patients are expected to take the medications indefinitely despite the lack of research regarding long-term adverse effects. Concerns regarding the adverse effects of these medications has led the United States National Institutes of Health to add a link for post-finasteride syndrome to its Genetic and Rare Disease Information Center. Herein, the authors report the results of a literature search reviewing adverse events of 5-alpha reductase inhibitors as they relate to prostate cancer, psychological effects, sexual health, and use in women. Several large studies found no increase in incidence of prostate cancer, a possible increase of high-grade cancer when detected, and no change in survival rate with 5-alpha reductase inhibitor use. Currently, there is no direct link between 5-alpha reductase inhibitor use and depression; however, several small studies have led to depression being listed as a side effect on the medication packaging. Sexual effects including erectile dysfunction and decreased libido and ejaculate were reported in as many as 3.4 to 15.8 percent of men. To date, there are very few studies evaluating 5-alpha reductase inhibitor use in women. Risks include birth defects in male fetuses if used in pregnancy, decreased libido, headache, gastrointestinal discomfort, and isolated reports of changes in menstruation, acne, and dizziness. Overall, 5-alpha reductase inhibitors were well-tolerated in both men and women, but not without risk, highlighting the importance of patient education prior to treatment.

BACKGROUND
Female patients undergoing anticancer treatment are at elevated risk of adverse ovarian outcomes including infertility and premature ovarian insufficiency (POI), which is associated with short- and long-term health risks. Anti-Müllerian hormone (AMH) is a key biomarker of ovarian reserve, but its role prior to and after cancer treatment is less well understood.
OBJECTIVE AND RATIONALE
To conduct a systematic review evaluating AMH as a biomarker of ovarian reserve and POI before and after anticancer treatment, which has become a pressing clinical issue in reproductive medicine. There are a large number of observational studies, but differences in patient groups, cancer diagnoses and study design make this a confusing field that will benefit from a thorough and robust review.
SEARCH METHODS
A systematic literature search for AMH in women with cancer was conducted in PubMed, Embase and Cochrane Central Register of Controlled Trials up to 1 April 2021. Bias review was conducted using the Risk of Bias In Non-randomized Studies of Interventions (ROBINS-I) protocol along with qualitative assessment of quality. Exploratory subgroups were established based on age, cancer type and length of follow-up.
OUTCOMES
Ninety-two publications (N = 9183 patients) were included in this analysis after quality and bias review. Reduced/undetectable AMH was consistently identified in 69/75 studies (92%) following chemotherapy or radiotherapy, with reductions ranging from 42% to concentrations below the limit of detection, and many reporting mean or median declines of ≥90%. Where longitudinal data were analysed (42 studies), a majority (33/42 (79%)) of studies reported at least partial recovery of AMH at follow-up, however, effect estimates were highly variable, reflecting that AMH levels were strongly impacted by anticancer treatment (i.e. the chemotherapy regimen used and the number of treatment cycles need), with recovery and its degree determined by treatment regimen, age and pre-treatment AMH level. In 16/31 (52%) publications, oligo/amenorrhoea was associated with lower post-treatment AMH consistent with impending POI, although menstruation and/or pregnancy were reported in patients with low or undetectable AMH. Long-term (>5 years) follow-up of paediatric patients following cancer treatment also found significantly lower AMH compared with control groups in 14/20 (70%) of studies, with very variable effect sizes from complete loss of AMH to full recovery depending on treatment exposure, as in adult patients.
WIDER IMPLICATIONS
AMH can be used to identify the damaging effect of cancer treatments on ovarian function. This can be applied to individual women, including pre-pubertal and adolescent girls, as well as comparing different treatment regimens, ages and pre-treatment AMH levels in populations of women. While there was evidence for its value in the diagnosis of POI after cancer treatment, further studies across a range of diagnoses/treatment regimens and patient ages are required to clarify this, and to quantify its predictive value. A major limitation for the use of AMH clinically is the very limited data relating post-treatment AMH levels to fertility, duration of reproductive lifespan or time to POI; analysis of these clinically relevant outcomes will be important in further research.

Revista Colombiana de Obstetricia Y... Jun 2020To conduct a systematic review of the literature and assess the acceptability and safety of the menstrual cup as a feminine hygiene product.
OBJECTIVES
To conduct a systematic review of the literature and assess the acceptability and safety of the menstrual cup as a feminine hygiene product.
MATERIALS AND METHODS
A search was conducted in the PubMed, Cochrane Library, Scopus, PopLine and Google Scholar databases for publications be- tween 1966 and July 2019. The terms ("Menstrual" AND "Cup") OR ("Copa" AND "Menstrual") were used. Quantitative, qualitative and mixed studies were included, as well as case series and case reports published in English and Spanish assessing the menstrual cup in women in childbearing age. The studies were selected and the data extracted by two reviewers working independently. Acceptability and safety were assessed as the primary result. The summary of the information is presented in narrative form.
RESULTS
Overall, 737 titles were found for initial review and, in the end, 38 studies were included in this work. The acceptability of the menstrual cup ranges between 35 % and 90 %. Between 10 to 45 % of women found it difficult to use. It was described as more comfortable when compared to tampons and pads. Continued use of the cup ranges between 48 and 94 %. In terms of safety, there was one case of toxic shock syndrome, one case of mechanical entrapment, and another case of allergy; and a higher risk of expulsion was found among intrauterine device users.
CONCLUSION
The menstrual cup appears to be a comfortable, safe and efficient option for menstrual hygiene. Further randomized controlled studies and long-term prospective cohort studies are needed in order to determine the risk of complications due to excess bacterial colonization or retrograde menstruation.

BACKGROUND
Polycystic ovarian syndrome (PCOS) is characterised by the clinical signs of oligo-amenorrhoea, infertility and hirsutism. Conventional treatment of PCOS includes a range of oral pharmacological agents, lifestyle changes and surgical modalities. Beta-endorphin is present in the follicular fluid of both normal and polycystic ovaries. It was demonstrated that the beta-endorphin levels in ovarian follicular fluid of otherwise healthy women who were undergoing ovulation were much higher than the levels measured in plasma. Given that acupuncture impacts on beta-endorphin production, which may affect gonadotropin-releasing hormone (GnRH) secretion, it is postulated that acupuncture may have a role in ovulation induction via increased beta-endorphin production effecting GnRH secretion. This is an update of our previous review published in 2016.
OBJECTIVES
To assess the effectiveness and safety of acupuncture treatment for oligo/anovulatory women with polycystic ovarian syndrome (PCOS) for both fertility and symptom control.
SEARCH METHODS
We identified relevant studies from databases including the Gynaecology and Fertility Group Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, CNKI, CBM and VIP. We also searched trial registries and reference lists from relevant papers. CENTRAL, MEDLINE, Embase, PsycINFO, CNKI and VIP searches are current to May 2018. CBM database search is to November 2015.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) that studied the efficacy of acupuncture treatment for oligo/anovulatory women with PCOS. We excluded quasi- or pseudo-RCTs.
DATA COLLECTION AND ANALYSIS
Two review authors independently selected the studies, extracted data and assessed risk of bias. We calculated risk ratios (RR), mean difference (MD), standardised mean difference (SMD) and 95% confidence intervals (CIs). Primary outcomes were live birth rate, multiple pregnancy rate and ovulation rate, and secondary outcomes were clinical pregnancy rate, restored regular menstruation period, miscarriage rate and adverse events. We assessed the quality of the evidence using GRADE methods.
MAIN RESULTS
We included eight RCTs with 1546 women. Five RCTs were included in our previous review and three new RCTs were added in this update of the review. They compared true acupuncture versus sham acupuncture (three RCTs), true acupuncture versus relaxation (one RCT), true acupuncture versus clomiphene (one RCT), low-frequency electroacupuncture versus physical exercise or no intervention (one RCT) and true acupuncture versus Diane-35 (two RCTs). Studies that compared true acupuncture versus Diane-35 did not measure fertility outcomes as they were focused on symptom control.Seven of the studies were at high risk of bias in at least one domain.For true acupuncture versus sham acupuncture, we could not exclude clinically relevant differences in live birth (RR 0.97, 95% CI 0.76 to 1.24; 1 RCT, 926 women; low-quality evidence); multiple pregnancy rate (RR 0.89, 95% CI 0.33 to 2.45; 1 RCT, 926 women; low-quality evidence); ovulation rate (SMD 0.02, 95% CI -0.15 to 0.19, I = 0%; 2 RCTs, 1010 women; low-quality evidence); clinical pregnancy rate (RR 1.03, 95% CI 0.82 to 1.29; I = 0%; 3 RCTs, 1117 women; low-quality evidence) and miscarriage rate (RR 1.10, 95% CI 0.77 to 1.56; 1 RCT, 926 women; low-quality evidence).Number of intermenstrual days may have improved in participants receiving true acupuncture compared to sham acupuncture (MD -312.09 days, 95% CI -344.59 to -279.59; 1 RCT, 141 women; low-quality evidence).True acupuncture probably worsens adverse events compared to sham acupuncture (RR 1.16, 95% CI 1.02 to 1.31; I = 0%; 3 RCTs, 1230 women; moderate-quality evidence).No studies reported data on live birth rate and multiple pregnancy rate for the other comparisons: physical exercise or no intervention, relaxation and clomiphene. Studies including Diane-35 did not measure fertility outcomes.We were uncertain whether acupuncture improved ovulation rate (measured by ultrasound three months post treatment) compared to relaxation (MD 0.35, 95% CI 0.14 to 0.56; 1 RCT, 28 women; very low-quality evidence) or Diane-35 (RR 1.45, 95% CI 0.87 to 2.42; 1 RCT, 58 women; very low-quality evidence).Overall evidence ranged from very low quality to moderate quality. The main limitations were failure to report important clinical outcomes and very serious imprecision.
AUTHORS' CONCLUSIONS
For true acupuncture versus sham acupuncture we cannot exclude clinically relevant differences in live birth rate, multiple pregnancy rate, ovulation rate, clinical pregnancy rate or miscarriage. Number of intermenstrual days may improve in participants receiving true acupuncture compared to sham acupuncture. True acupuncture probably worsens adverse events compared to sham acupuncture.No studies reported data on live birth rate and multiple pregnancy rate for the other comparisons: physical exercise or no intervention, relaxation and clomiphene. Studies including Diane-35 did not measure fertility outcomes as the women in these trials did not seek fertility.We are uncertain whether acupuncture improves ovulation rate (measured by ultrasound three months post treatment) compared to relaxation or Diane-35. The other comparisons did not report on this outcome.Adverse events were recorded in the acupuncture group for the comparisons physical exercise or no intervention, clomiphene and Diane-35. These included dizziness, nausea and subcutaneous haematoma. Evidence was very low quality with very wide CIs and very low event rates.There are only a limited number of RCTs in this area, limiting our ability to determine effectiveness of acupuncture for PCOS.
