Review
Menstrual health represents a state of complete physical, mental, and social well-being in relation to a woman's menstrual cycle. From a health literacy perspective, knowledge acquisition and expertise are dependent upon the degree to which an individual can find, access, understand, critically analyse, and apply health information. Therefore, menstrual health literacy can be used to describe the state of knowledge acquisition and application specific to menstrual health-related issues. Menstrual health literacy is low among female athletes, their coaches, and practitioners, and few evidence-informed education or implementation strategies exist to improve menstrual health literacy in sport. Moreover, athletes seldom discuss their menstrual cycles or hormonal contraceptive use with their coaches, despite experiencing menstrual symptoms and/or disturbances and perceiving their menstrual cycles/hormonal contraceptive use to affect performance. Barriers to communication about menstrual cycle- and hormonal contraceptive-related topics include a perceived lack of knowledge among athletes, coaches, and practitioners, concerns about how conversations on these issues will affect interpersonal relationships, and a lack of formal and informal discussion forums. Whilst evidence relating to the effects of the menstrual cycle phase and hormonal contraceptive use on training and performance is currently limited, with existing studies often lacking methodological rigour, impactful steps can still be made to support female athletes. This cornerstone review highlights the current state of menstrual health literacy among athletes, coaches, and practitioners, and provides recommendations for improving menstrual health literacy in sport.

Review
Abnormal uterine bleeding is a frequent symptom in the perimenopause. Causes are numerous, ranging from physiological reactions due to decreasing/unstable ovarian function to premalignant and malignant conditions. Benign findings such as endometrial polyps and myomas increase with age, leading to more abnormal uterine bleeding in the perimenopause. Cervical and vaginal causes of abnormal uterine bleeding should be excluded by speculum examination. Sexually transmitted diseases or pregnancy should be ruled out. Measurement of haemoglobin and iron levels, human chorion gonadotropin and thyroid hormones are relevant in selected cases. Transvaginal ultrasound is an ideal first step for the evaluation of perimenopausal abnormal uterine bleeding. Saline or gel contrast sonohysterography improves the diagnostic accuracy. Based on the ultrasound findings, invasive procedures such as endometrial biopsy or hysteroscopy can be planned. Once premalignant and malignant causes are excluded, the necessity for treatment can be evaluated in collaboration with the patient. Heavy menstrual bleeding causing anaemia will need immediate treatment. In less severe cases and in intermenstrual bleeding, expectant management can be considered. Hormonal treatment, such as oral progestogens, combined oral contraceptives or insertion of the levonorgestrel intrauterine system, may be a possibility if anovulatory bleeding is interfering with quality of life. The amount of bleeding can be reduced both by antifibrinolytic and non-steroidal anti-inflammatory drugs, progestogens and the levonorgestrel intrauterine system. Focal intrauterine lesions such as endometrial polyps or submucous myomas may require operative hysteroscopic procedures. Endometrial ablation or endometrial resection are good choices in selected cases, but some women will need a hysterectomy to treat their abnormal uterine bleeding in perimenopause.

Review
PURPOSE OF REVIEW
This review article explores the evidence regarding sugammadex (MSD Australia) and its potential interaction with hormonal contraceptives. The impact of recent clinical trials and review articles is examined.
RECENT FINDINGS
Recent clinical data suggest that the interaction between sugammadex and estrogen and progesterone concentrations may not be clinically significant and may confer some protection against ovulation. There are no clinical trials reporting interactions between sugammadex and the exogenous hormonal compounds found in oral contraceptive pills. The method of contraception is an important consideration, as sugammadex theoretically affects oral and nonoral, and combined versus single agent methods differently. Two large retrospective database studies have reported two cases of pregnancy postoperatively in patients on hormonal contraceptives whose anesthetic included sugammadex.
SUMMARY
Strong clinical evidence to support or refute claims of a significant impact of sugammadex on contraceptive efficacy in women on contraception is lacking. The existing evidence does not suggest a basis for concern regarding the impact of sugammadex on contraception in the perioperative setting.

Review
INTRODUCTION
Drospirenone/estetrol (DRSP/E4) is a combined oral contraceptive (COC) recently approved in several countries. It is composed of 15 mg of E4, a natural estrogen produced by human fetal liver throughout pregnancy, and 3 mg of DRSP, the first synthetic progestin used in oral contraception derived from 17-α-spirolactone. E4 and DRSP synergistically prevent pregnancy by inhibiting ovulation. E4 differs from 17-β-estradiol or ethinylestradiol because it represents a native estrogen with selective action in tissues (NEST), therefore it displays both agonist and antagonist estrogenic effects in different tissues.
AREAS COVERED
In this paper, we reviewed the scientific literature published in English prior to April 2023 and gathered information on the pharmacodynamics and pharmacokinetics of DRSP, E4 and their combination for contraception. We also proposed possible clinical applications based on the characteristics of the components of this COC.
EXPERT OPINION
E4/DRSP-based COC has shown high tolerability, safety and satisfaction and may represent a viable choice in young girls in need of oral contraception and pill users who suffer from high cholesterol, breast tenderness or water retention. Moreover, this new COC shows higher scheduled bleeding rate compared to other pills containing natural estrogens. All the data are reassuring, permitting long-term use.

IMPORTANCE
Hormonal contraception has been linked to mood symptoms and the ability to recognize emotions after short periods of treatment, whereas the mental health of users of long-term hormonal contraceptives has had limited investigation.
OBJECTIVE
To evaluate whether short-term hormonal withdrawal, which users of combined oral contraceptives (COCs) undergo once a month (pill pause), was associated with altered mood and emotional recognition in long-term users of COCs.
DESIGN, SETTING, AND PARTICIPANTS
This case-control study included a community sample of individuals assigned female sex at birth who identified as women and used COC for 6 months or longer. The control group included women with natural menstrual cycles who otherwise fulfilled the same inclusion criteria. The study was conducted between April 2021 and June 2022 in Salzburg, Austria.
EXPOSURE
COC users and women with natural menstrual cycles were tested twice within a month, once during their active pill phase or luteal phase and once during their pill pause or menses.
MAIN OUTCOMES AND MEASURES
Negative affect, anxiety, and mental health problems were assessed during each session. The percentage increase in mental health symptoms was calculated during the pill pause compared with that during the active intake phase in COC users. How this change compared with mood fluctuations along the menstrual cycle in women with natural menstrual cycles was assessed.
RESULTS
A total of 181 women aged 18 to 35 years (mean [SD] age, 22.7 [3.5] years) were included in the analysis (61 women with androgenic COC use, 59 with antiandrogenic COC use, 60 women with a menstrual cycle not taking COCs). COC users showed a 12.67% increase in negative affect (95% CI, 6.94%-18.39%), 7.42% increase in anxiety (95% CI, 3.43%-11.40%), and 23.61% increase in mental health symptoms (95% CI, 16.49%-30.73%; P < .001) during the pill pause compared with the active intake phase. The effect size of this change did not differ depending on progestin type (negative affect: F1,117 = 0.30, P = .59; state anxiety: F1,117 = 2.15, P = .15; mental health: F1,117 = .16, P = .69) or ethinylestradiol dose (negative affect: F1,57 = .99, P = .32; state anxiety: F1,57 = 2.30, P = .13; mental health: F1,57 = .14, P = .71) was comparable with mood changes along the menstrual cycle in women with natural cycles (negative affect: F2,175 = 0.13, P = .87; state anxiety: F2,175 = 0.14, P = .32; mental health: F2,175 = 0.65, P = .52). Mood worsening during the pill pause was more pronounced in women with higher baseline depression scores (negative affect increase of 17.95% [95% CI, 7.80%-28.10%] in COC users with higher trait depression [BDI >8]). Emotion recognition performance did not differ between active pill phase and pill pause.
CONCLUSIONS AND RELEVANCE
In this case-control study of long-term COC users, withdrawal from contraceptive steroids during the pill pause was associated with adverse mental health symptoms similar to those experienced by women during menses with withdrawal from endogenous steroids. These results question the use of the pill pause from a mental health perspective. Long-term COC users may benefit more from the mood-stabilizing effects of COCs in cases of continuous intake.

Meta-Analysis
The Effect of Hormonal Contraceptive Use on Skeletal Muscle Hypertrophy, Power and Strength Adaptations to Resistance Exercise Training: A Systematic Review and Multilevel Meta-analysis.
BACKGROUND
Resistance exercise training is widely used by general and athletic populations to increase skeletal muscle hypertrophy, power and strength. Endogenous sex hormones influence various bodily functions, including possibly exercise performance, and may influence adaptive changes in response to exercise training. Hormonal contraceptive (HC) use modulates the profile of endogenous sex hormones, and therefore, there is increasing interest in the impact, if any, of HC use on adaptive responses to resistance exercise training.
OBJECTIVE
Our aim is to provide a quantitative synthesis of the effect of HC use on skeletal muscle hypertrophy, power and strength adaptations in response to resistance exercise training.
METHODS
A systematic review with meta-analysis was conducted on experimental studies which directly compared skeletal muscle hypertrophy, power and strength adaptations following resistance exercise training in hormonal contraceptive users and non-users conducted before July 2023. The search using the online databases PUBMED, SPORTDiscus, Web of Science, Embase and other supplementary search strategies yielded 4669 articles, with 8 articles (54 effects and 325 participants) meeting the inclusion criteria. The methodological quality of the included studies was assessed using the "Tool for the assessment of study quality and reporting in exercise".
RESULTS
All included studies investigated the influence of oral contraceptive pills (OCP), with no study including participants using other forms of HC. The articles were analysed using a meta-analytic multilevel maximum likelihood estimator model. The results indicate that OCP use does not have a significant effect on hypertrophy [0.01, 95% confidence interval (CI) [- 0.11, 0.13], t = 0.14, p = 0.90), power (- 0.04, 95% CI [- 0.93, 0.84], t = - 0.29, p = 0.80) or strength (0.10, 95% CI [- 0.08, 0.28], t = 1.48, p = 0.20).
DISCUSSION
Based on the present analysis, there is no evidence-based rationale to advocate for or against the use of OCPs in females partaking in resistance exercise training to increase hypertrophy, power and/or strength. Rather, an individualised approach considering an individual's response to OCPs, their reasons for use and menstrual cycle history may be more appropriate.

Review
INTRODUCTION
Migraine, a neurovascular headache disorder, is a leading cause of disability worldwide. Within the multifaceted pathophysiology of migraine, hormonal fluctuations play an evident triggering and exacerbating role, pointing toward the need for identification and proper usage of both existing and new hormonal targets in migraine treatment.
AREAS COVERED
With a threefold higher incidence of migraine in women than in men, the authors delve into sex hormone-related events in migraine patients. A comprehensive overview is given of existing hormonal therapies, including oral contraceptives, intrauterine devices, transdermal and subcutaneous estradiol patches, gnRH-agonists, oral testosterone, and 5α reductase inhibitors. The authors discuss their effectiveness and risks, noting their suitability for different patient profiles. Next, novel evolving hormonal treatments, such as oxytocin and prolactin, are explored. Lastly, the authors cover hormonal conditions associated with migraine, such as polycystic ovary syndrome, endometriosis, and transgender persons receiving gender affirming hormone therapy, aiming to provide more personalized and effective solutions for migraine management.
EXPERT OPINION
Rigorous research into both existing and new hormonal targets, as well as the underlying pathophysiology, is needed to support a tailored approach in migraine treatment, in an ongoing effort to alleviate the impact of migraine on individuals and society.

The Journal of Clinical Endocrinology... Jan 2024Polycystic ovary syndrome (PCOS) affects more than 1 in 10 women. (Meta-Analysis)
Meta-Analysis
CONTEXT
Polycystic ovary syndrome (PCOS) affects more than 1 in 10 women.
OBJECTIVE
As part of the 2023 International PCOS Guidelines update, comparisons between combined oral contraceptive pills (COCP), metformin, and combination treatment were evaluated.
DATA SOURCES
Ovid Medline, Embase, PsycINFO, All EBM, and CINAHL were searched.
STUDY SELECTION
Women with PCOS included in randomized controlled trials (RCTs).
DATA EXTRACTION
We calculated mean differences and 95% CIs regarding anthropometrics, metabolic, and hyperandrogenic outcomes. Meta-analyses and quality assessment using GRADE were performed.
DATA SYNTHESIS
The search identified 1660 publications; 36 RCTs were included. For hirsutism, no differences were seen when comparing metformin vs COCP, nor when comparing COCP vs combination treatment with metformin and COCP. Metformin was inferior on free androgen index (FAI) (7.08; 95% CI 4.81, 9.36), sex hormone binding globulin (SHBG) (-118.61 nmol/L; 95% CI -174.46, -62.75) and testosterone (0.48 nmol/L; 95% CI 0.32, 0.64) compared with COCP. COCP was inferior for FAI (0.58; 95% CI 0.36, 0.80) and SHBG (-16.61 nmol/L; 95% CI -28.51, -4.71) compared with combination treatment, whereas testosterone did not differ. Metformin lowered insulin (-27.12 pmol/L; 95% CI -40.65, -13.59) and triglycerides (-0.15 mmol/L; 95% CI -0.29, -0.01) compared with COCP. COCP was inferior for insulin (17.03 pmol/L; 95% CI 7.79, 26.26) and insulin resistance (0.44; 95% CI 0.17, 0.70) compared with combination treatment.
CONCLUSIONS
The choice of metformin or COCP treatment should be based on symptoms, noting some biochemical benefits from combination treatment targeting both major endocrine disturbances seen in PCOS (hyperinsulinemia and hyperandrogenism).
