Abstract
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.

Abstract
OBJECTIVES To synthesize published literature on POP effectiveness and efficacy. STUDY DESIGN We searched PubMed Central, PubMed, and the Cochrane library through March 07, 2022. We included articles written in English reporting a Pearl Index or life table rate for pregnancy. We excluded articles only assessing formulations that: were never marketed globally, are only sold in combination with estrogen, are currently sold only for noncontraceptive purposes, or were not given to participants continuously. Four researchers independently extracted data and two analyzed data using Excel and R. RESULTS We included 54 studies. Among studies at low or moderate risk of bias, the median Pearl Index rate (the failure rate during typical use) was 1.63 (range 0.00-14.20, IQR 4.03) and the median method failure Pearl Index rate (the failure rate during perfect use) was 0.97 (range 0.40-6.50, IQR 0.68). Excluding the newer formulations, Desogestrel and Drospirenone, which are closer to combined oral contraceptives in that they prevent pregnancy by inhibiting ovulation, the median Pearl Index rate is 2.00 (range 0.00-14.12, IQR 2.5) and the median method failure Pearl Index rate is 1.05 (range 0.00-10.90, IQR 1.38). CONCLUSIONS Among studies at low or moderate risk of bias, the median Pearl Index rate during typical POP use was much lower than currently estimated (7.00), while the median perfect use rate was similar to current estimates. IMPLICATIONS Future research should investigate the possibility that POPs may be much more effective during typical use than currently believed.

Abstract
Although almost 0.7% of the Brazilian population identifies as transgender, there is currently no training for healthcare professionals to provide comprehensive care to these patients, including the discussion of reproductive planning. The use of testosterone promotes amenorrhea in the first months of use; however, this effect does not guarantee contraceptive efficacy, and, consequently, increases the risks of unplanned pregnancy. The present article is an integrative review with the objective of evaluating and organizing the approach of contraceptive counseling for the transgender population who were assigned female at birth. We used the PubMed and Embase databases for our search, as well as international guidelines on care for the transgender population. Of 88 articles, 7 were used to develop the contraceptive counseling model. The model follows the following steps: 1. Addressing the information related to the need for contraception; 2. Evaluation of contraindications to the use of contraceptive methods (hormonal and nonhormonal); and 3. Side effects and possible discomfort associated with the use of contraception. The contraceptive counseling model is composed of 18 questions that address the indications and contraindications to the use of these methods, and a flowchart to assist patients in choosing a method that suits their needs.

Abstract
Polycystic ovary syndrome (PCOS) is a common endocrine disorder in reproductive-aged women, characterized by hyperandrogenism, oligo/anovulation, and polycystic ovarian morphology. Combined oral contraceptives (COCs), along with lifestyle modifications, represent the first-line medical treatment for the long-term management of PCOS. Containing low doses of estrogen and different types of progestin, COCs restore menstrual cyclicity, improve hyperandrogenism, and provide additional benefits such as reducing the risk of endometrial cancer. However, potential cardiometabolic risk associated with these agents has been a concern. COCs increase the risk of venous thromboembolism (VTE), related both to the dose of estrogen and the type of progestin involved. Arterial thrombotic events related to COC use occur much less frequently, and usually not a concern for young patients. All patients diagnosed with PCOS should be carefully evaluated for cardiometabolic risk factors at baseline, before initiating a COC. Age, smoking, obesity, glucose intolerance or diabetes, hypertension, dyslipidemia, thrombophilia, and family history of VTE should be recorded. Patients should be re-assessed at consecutive visits, more closely if any baseline cardiometabolic risk factor is present. Individual risk assessment is the key in order to avoid unfavorable outcomes related to COC use in women with PCOS.

Abstract
Progestin-only contraception has become increasingly popular among adolescents. However, patients, parents, and providers share concerns regarding the potential impact that progestin-only contraception may have on breast growth. We sought to explore the impact of progestin-only contraception on breast hypertrophy and symptomatology in adolescents with macromastia. METHODS Patients between the ages of 12 and 21 years undergoing reduction mammaplasty were prospectively assessed for baseline and postoperative breast symptomatology and medication use. The medical records of female controls within the same age range were retrospectively reviewed. RESULTS A total of 378 participants with macromastia and 378 controls were included in analyses. A higher proportion of controls used progestin-only methods compared with participants with macromastia (28.0% versus 5.3%, P < 0.001). The most commonly prescribed methods were the depot medroxyprogesterone acetate injection (31.0%), levonorgestrel-containing intrauterine device (31.0%), and subdermal implant (26.2%). Patients with macromastia who used progestin-only contraception had a greater amount of breast tissue resected during reduction mammaplasty (P = 0.04), reported greater musculoskeletal pain (P = 0.008), and were roughly 500% more likely to experience breast pain (odds ratio, 4.94; 95% confidence interval, 1.58-15.47; P = 0.005) than those with macromastia who never used hormonal contraception. CONCLUSIONS Adolescents with macromastia who use progestin-only contraception may have greater breast hypertrophy and worse breast and musculoskeletal pain. When appropriate, providers may wish to consider other contraception methods for patients who are at-risk for breast hypertrophy or those who suffer from macromastia-related symptoms.

Abstract
Objectives To evaluate contraceptive effectiveness and safety of oral drospirenone 4 mg 24/4-day regimen in the United States. Study design We performed a prospective, single-arm, multicenter phase 3 trial in sexually active women for up to thirteen 28-day treatment cycles. Primary outcome was the Pearl index, calculated using confirmed on-drug pregnancies and evaluable cycles in nonbreastfeeding women aged ≤ 35 years. We assessed adverse events (AEs), including hyperkalemia and venous thromboembolism. Results Of 1006 women who received at least one dose of drospirenone, 352 women (35.0%) completed the trial and 654 (65.0%) women discontinued before trial end. Most participants (92.2%) were ≤ 35 years; one third had a body mass index (BMI) ≥ 30 kg/m2. Among nonbreastfeeding women aged ≤ 35 years, there were 17 pregnancies (Pearl index: 4.0; 95% confidence interval [CI], 2.3-6.4; n = 953), of which three were unconfirmed and two were from sites excluded from the main analysis for major breaches of Food and Drug Administration regulations. The Pearl index was 2.9 (95% CI: 1.5-5.1) for confirmed pregnancies among 915 nonbreastfeeding women aged ≤ 35 years from sites with no protocol violations. Nearly all (95.4%) treatment-emergent AEs were mild or moderate in intensity. No cases of venous thromboembolism were reported. The frequency of hyperkalemia was 0.5%. Women with baseline systolic/diastolic blood pressure ≥ 130/85 mmHg had a mean reduction from baseline in blood pressure at exit visit (- 8.5/- 4.9 mmHg; n = 119). No other clinically relevant changes were observed. Participant satisfaction was high. Conclusion Drospirenone 4 mg 24/4 regimen provides effective contraception with a good safety/tolerability profile in a broad group of women, including overweight or obese women. Implications This new progestin-only contraceptive, drospirenone 4 mg in a 24/4 regimen, provides a contraceptive option for the majority of women regardless of blood pressure or BMI.

Abstract
BACKGROUND AND OBJECTIVE Unplanned pregnancies can lead to poorer maternal and child health outcomes. The Australian Therapeutic Goods Administration committee rejected reclassifying a range of oral contraceptive pills (OCPs) from prescription to pharmacist-only medicines in 2015, mainly based on safety concerns. Improving access to OCPs may encourage some women to use contraceptives or switch from other contraceptive methods. However, some adverse events may increase and some women may stop using condoms, increasing their risk of sexually transmitted infections. This study aimed to estimate the cost effectiveness of reclassifying OCPs from prescription to pharmacist-only. PERSPECTIVE Healthcare system. SETTING Australian primary care. METHODS A Markov model was used to synthesise data from a variety of sources. The model included all Australian women aged 15-49 years (N = 5,644,701). The time horizon was 35 years. Contraceptive use before reclassification was estimated using data from the Household, Income and Labour Dynamics in Australia (HILDA) survey, while survey data informed use after reclassification. Health outcomes included pregnancies, pregnancy outcomes (live birth, miscarriage, stillbirth, ectopic pregnancy and abortion), sexually transmitted infections, adverse events (venous thromboembolism, depression, myocardial infarction and stroke), ovarian cancer cases and quality-adjusted life-years. Costs included those related to general practitioner and specialist consultations, contraceptives and other medicines, pharmacist time, hospitalisations and adverse events. All costs were reported in 2016 Australian Dollars. A 5% discount rate was applied to health outcomes and costs. RESULTS Reclassifying OCPs resulted in 85.70 million quality-adjusted life-years experienced and costs of $46,910.14 million over 35 years, vs. 85.68 million quality-adjusted life-years experienced and costs of $50,274.95 million with OCPs remaining prescription-only. Thus, reclassifying OCPs was more effective and cost saving. However, a sensitivity analysis found that more research on the probability of pregnancy in women not using contraception and not trying to conceive is needed. CONCLUSION Reclassifying OCPs is likely to be considered cost effective by Australian decision makers.

Abstract
Background To determine whether oral norethindrone acetate is superior to combined oral contraceptives (OCP) in delaying menstruation and preventing breakthrough bleeding when started late in the cycle. Methods This article comprises of a case control study followed by a pilot randomized controlled study. In the first study, four women who presented late in their cycle and desired avoiding vaginal bleeding within 10 days before a wedding were started on norethindrone 5 mg three times daily and compared to age matched controls started on OCPs. Subsequently, a randomized controlled pilot study (n = 50) comparing OCPs to norethindrone for the retiming of menses was conducted. Percentage of women reporting spotting were compared with level of statistical significance set at p < 0.05. Results Of the norethindrone treated group, only 2 women (8%) reported spotting compared with 10 women (43%) in the control group (p < 0.01). Norethindrone recipients experienced significant weight gain, which resolved after cessation of therapy and had heavier withdrawal bleed (p < 0.04) when compared to controls. Patient satisfaction was significantly higher in the norethindrone group, with 80% willing to choose this method again. Time to conceive was significantly shorter in the norethindrone group (p < 0.03). Conclusions Norethindrone, begun on or before cycle day 12, is superior for women who desire to avoid breakthrough bleeding and maintain fertility when compared to OCPs. It is an ideal approach in patients presenting late in their cycle and who desire delaying menses as well as in circumstances when even minute amounts of breakthrough bleeding cannot be tolerated. Trial registration Clinicaltrials.gov NCT03594604, July 2018. Retrospectively registered.

Abstract
BACKGROUND Oral contraceptives are still associated with high discontinuation rates, despite their efficacy. There is a wide choice of oral contraceptives available, and the aim of this study was to assess continuation rates, bleeding profile acceptability, and the satisfaction of women in the first year of using a contraceptive pill containing estradiol valerate and dienogest (E2V/DNG) versus a progestogen-only pill (POP) in a real-life setting after discontinuing an ethinylestradiol-containing pill. METHODS AND RESULTS In this prospective, noninterventional, observational study, 3,152 patients were included for the efficacy analyses (n=2,558 women in the E2V/DNG group and n=592 in the POP group (two patients fulfilled the criteria of the efficacy population, but the used product was not known). Women had been taking an ethinylestradiol-containing pill ≥3 months before deciding to switch to the E2V/DNG pill or a POP. Overall, 19.8% (n=506) of E2V/DNG users and 25.8% (n=153) of POP users discontinued their prescribed pill. The median time to discontinuation was 157.0 days and 127.5 days, respectively. Time to discontinuation due to bleeding (P<0.0001) or other reasons (P=0.022) was significantly longer in the E2V/DNG group versus the POP group. The E2V/DNG pill was also associated with shorter (48.7% vs 44.1%), lighter (54% vs 46.1%), and less painful bleeding (91.1% vs 73.7%) and greater user satisfaction (80.7% vs 64.6%) than POP use, within 3-5 months after switch. CONCLUSION The E2V/DNG pill was associated with higher rates of continuation, bleeding profile acceptability, and user satisfaction than POP use and may be an alternative option for women who are dissatisfied with their current pill.

Abstract
BACKGROUND Progestin-only contraceptives (POCs) are appropriate for many women who cannot or should not take estrogen. POCs include injectables, intrauterine contraception, implants, and oral contraceptives. Many POCs are long-acting, cost-effective methods of preventing pregnancy. However, concern about weight gain can deter the initiation of contraceptives and cause early discontinuation among users. OBJECTIVES The primary objective was to evaluate the association between progestin-only contraceptive use and changes in body weight. SEARCH METHODS Until 4 August 2016, we searched MEDLINE, CENTRAL, POPLINE, LILACS, ClinicalTrials.gov, and ICTRP. For the initial review, we contacted investigators to identify other trials. SELECTION CRITERIA We considered comparative studies that examined a POC versus another contraceptive method or no contraceptive. The primary outcome was mean change in body weight or mean change in body composition. We also considered the dichotomous outcome of loss or gain of a specified amount of weight. DATA COLLECTION AND ANALYSIS Two authors extracted the data. Non-randomized studies (NRS) need to control for confounding factors. We used adjusted measures for the primary effects in NRS or the results of matched analysis from paired samples. If the report did not provide adjusted measures for the primary analysis, we used unadjusted outcomes. For RCTs and NRS without adjusted measures, we computed the mean difference (MD) with 95% confidence interval (CI) for continuous variables. For dichotomous outcomes, we calculated the Mantel-Haenszel odds ratio (OR) with 95% CI. MAIN RESULTS We found 22 eligible studies that included a total of 11,450 women. With 6 NRS added to this update, the review includes 17 NRS and 5 RCTs. By contraceptive method, the review has 16 studies of depot medroxyprogesterone acetate (DMPA), 4 of levonorgestrel-releasing intrauterine contraception (LNG-IUC), 5 for implants, and 2 for progestin-only pills.Comparison groups did not differ significantly for weight change or other body composition measure in 15 studies. Five studies with moderate or low quality evidence showed differences between study arms. Two studies of a six-rod implant also indicated some differences, but the evidence was low quality.Three studies showed differences for DMPA users compared with women not using a hormonal method. In a retrospective study, weight gain (kg) was greater for DMPA versus copper (Cu) IUC in years one (MD 2.28, 95% CI 1.79 to 2.77), two (MD 2.71, 95% CI 2.12 to 3.30), and three (MD 3.17, 95% CI 2.51 to 3.83). A prospective study showed adolescents using DMPA had a greater increase in body fat (%) compared with a group not using a hormonal method (MD 11.00, 95% CI 2.64 to 19.36). The DMPA group also had a greater decrease in lean body mass (%) (MD -4.00, 95% CI -6.93 to -1.07). A more recent retrospective study reported greater mean increases with use of DMPA versus Cu IUC for weight (kg) at years 1 (1.3 vs 0.2), 4 (3.5 vs 1.9), and 10 (6.6 vs 4.9).Two studies reported a greater mean increase in body fat mass (%) for POC users versus women not using a hormonal method. The method was LNG-IUC in two studies (reported means 2.5 versus -1.3; P = 0.029); (MD 1.60, 95% CI 0.45 to 2.75). One also studied a desogestrel-containing pill (MD 3.30, 95% CI 2.08 to 4.52). Both studies showed a greater decrease in lean body mass among POC users. AUTHORS' CONCLUSIONS We considered the overall quality of evidence to be low; more than half of the studies had low quality evidence. The main reasons for downgrading were lack of randomizations (NRS) and high loss to follow-up or early discontinuation.These 22 studies showed limited evidence of change in weight or body composition with use of POCs. Mean weight gain at 6 or 12 months was less than 2 kg (4.4 lb) for most studies. Those with multiyear data showed mean weight change was approximately twice as much at two to four years than at one year, but generally the study groups did not differ significantly. Appropriate counseling about typical weight gain may help reduce discontinuation of contraceptives due to perceptions of weight gain.

Abstract
Women receiving vitamin K antagonists (VKAs) require adequate contraception because of the potential for fetal complications. It is unknown whether the use of hormonal therapy, especially those containing estrogens, is associated with recurrent venous thromboembolism (VTE) during anticoagulation. Despite the absence of data, World Health Organization guidelines state that use of estrogen-containing contraceptives confers an "unacceptable health risk" during established anticoagulation for VTE. We compared the incidences of recurrent VTE and abnormal uterine bleeding with and without concomitant hormonal therapy in women aged <60 years who were receiving anticoagulation with rivaroxaban or enoxaparin/VKA for confirmed VTE. Incidence densities in percentage per year were computed for the on and off estrogen-containing or progestin-only therapy periods. Cox regression models were fitted, with hormonal therapy (on vs off) as a time-dependent variable to derive the hazard ratio (HR) for the effects on recurrent VTE and abnormal uterine bleeding. In total, 1888 women were included. VTE incidence densities on and off hormonal therapy were 3.7%/year and 4.7%/year (adjusted HR, 0.56; 95% confidence interval [CI], 0.23-1.39), respectively, and were 3.7%/year and 3.8%/year, respectively, for estrogen-containing and progestin-only therapy. The adjusted HR for all abnormal uterine bleeding (on vs off hormonal therapy) was 1.02 (95% CI, 0.66-1.57). Abnormal uterine bleeding occurred more frequently with rivaroxaban than with enoxaparin/VKA (HR, 2.13; 95% CI, 1.57-2.89). Hormonal therapy was not associated with an increased risk of recurrent VTE in women receiving therapeutic anticoagulation. The observed increased risk of abnormal uterine bleeding with rivaroxaban needs further exploration.
