Assessing the effect of concerns about contraceptive-induced fertility impairment on hormonal contraceptive use by parity and residence: evidence from PMA Ethiopia 2020 cross-sectional survey.

OBJECTIVES: This study aims to describe patterns of beliefs about contraceptive-induced infertility and assess their relationship with current contraceptive use, including whether these relationships vary by parity and residence. DESIGN: We use data from Performance Monitoring for Action Ethiopia, a nationally representative, cross-sectional survey of 7491 women, aged 15-49, to assess agreement with the statement 'If I use family planning, I may have trouble getting pregnant next time I want to.' We used multilevel hierarchical models to identify the association between agreement and use of a hormonal method of contraception among 3882 sexually active, fecund women who wish to prevent pregnancy. We include interaction terms for parity and residence. RESULTS: 4 in 10 women disagreed (42.3%) and 2 in 10 strongly disagreed (20.7%) with the statement. Relative to women who strongly disagreed, women who disagreed and women who agreed had significantly lower odds of using a hormonal method of contraception (adjusted OR (aOR) 0.65, 95% CI 0.44 to 0.97 and 0.46, 95% CI 0.46, 95% CI 0.30 to 0.70). The effect of agreeing with the statement was strongest among high parity women (aOR 0.54, 95% CI 0.30 to 0.95). Greater agreement with the statement at the community-level use was associated with a reduction in the odds of using hormonal contraception but only among rural women. CONCLUSIONS: Efforts to address concerns around contraceptive-induced fertility impairment through the provision of comprehensive counselling and through community education or mass media campaigns are necessary, particularly among high-parity women and in rural communities. Interventions should acknowledge the possibility of delayed return to fertility for specific methods and attempt to address the root causes of concerns.

Effect of Menstrual Cycle and Hormonal Contraception on Musculoskeletal Health and Performance: Protocol for a Prospective Cohort Design and Cross-Sectional Comparison.

BACKGROUND: Women of reproductive age experience cyclical variation in the female sex steroid hormones 17ß-estradiol and progesterone during the menstrual cycle that is attenuated by some hormonal contraceptives. Estrogens perform a primary function in sexual development and reproduction but have nonreproductive effects on bone, muscle, and sinew tissues (ie, ligaments and tendons), which may influence injury risk and physical performance. OBJECTIVE: The purpose of the study is to understand the effect of the menstrual cycle and hormonal contraceptive use on bone and calcium metabolism, and musculoskeletal health and performance. METHODS: A total of 5 cohorts of physically active women (aged 18-40 years) will be recruited to participate: eumenorrheic, nonhormonal contraceptive users (n=20); combined oral contraceptive pill (COCP) users (n=20); hormonal implant users (n=20); hormonal intrauterine system users (n=20); and hormonal injection users (n=20). Participants must have been using the COCP and implant for at least 1 year and the intrauterine system and injection for at least 2 years. First-void urine samples and fasted blood samples will be collected for biochemical analysis of calcium and bone metabolism, hormones, and metabolic markers. Knee extensor and flexor strength will be measured using an isometric dynamometer, and lower limb tendon and stiffness, tone, and elasticity will be measured using a Myoton device. Functional movement will be assessed using a single-leg drop to assess the frontal plane projection angle and the qualitative assessment of single leg loading. Bone density and macro- and microstructure will be measured using ultrasound, dual-energy x-ray absorptiometry, and high-resolution peripheral quantitative computed tomography. Skeletal material properties will be estimated from reference point indentation, performed on the flat surface of the medial tibia diaphysis. Body composition will be assessed by dual-energy x-ray absorptiometry. The differences in outcome measures between the hormonal contraceptive groups will be analyzed in a one-way between-group analysis of covariance. Within the eumenorrheic group, the influence of the menstrual cycle on outcome measures will be assessed using a linear mixed effects model. Within the COCP group, differences across 2 time points will be analyzed using the paired-samples 2-tailed t test. RESULTS: The research was funded in January 2020, and data collection started in January 2022, with a projected data collection completion date of August 2024. The number of participants who have consented at the point of manuscript submission is 66. It is expected that all data analysis will be completed and results published by the end of 2024. CONCLUSIONS: Understanding the effects of the menstrual cycle and hormonal contraception on musculoskeletal health and performance will inform contraceptive choices for physically active women to manage injury risk.

Hormonal contraceptive use among women living with hypertension in sub-Saharan Africa: insights from 12 countries.

OBJECTIVES: Given the well-established link between hormonal contraceptives and hypertension risk, and the paucity of research on hormonal contraceptive use dynamics in this particular demographic, we hypothesize that there is a likelihood of low utilization of high-risk hormonal contraceptives among women living with hypertension in SSA. This study investigates the prevalence and factors associated with hormonal contraceptive use among women living with hypertension in the SSA. RESULTS: Only 18.5% of women living with hypertension used hormonal contraceptives. Hormonal contraceptive use was high among women with a higher level of education (aOR = 2.33; 95%CI: 1.73-3.14), those currently working (aOR = 1.38; 95%CI: 1.20-1.59), those who have heard about family planning on the radio (aOR = 1.27, 95%CI: 1.09-1.47), listened to the radio at least once a week (aOR = 1.29, 95%CI: 1.10-1.51), and those residing in rural areas (aOR = 1.32; 95%CI: 1.14-1.54). Conversely, women aged 45-49 exhibited a substantial decrease in the odds of hormonal contraceptive use (aOR = 0.23, 95%CI: 0.14-0.38) compared to younger women (15-19 years). Likewise, the odds of HCU were low among cohabiting (aOR = 0.66; 95%CI: 0.48-0.89) and previously married women (aOR = 0.67; 95%CI: 0.50-0.91) than never married women.

Hormonal Contraception and Sexual Function: A Review, Clinical Insights, and Management Considerations.

Most sexually active women of reproductive age have used contraception, with hormonal methods constituting approximately 40% of contraceptive choices. Among these hormonal options, combined oral contraceptives stand out as the most selected. Within this same demographic, sexual issues are prevalent. Although specific hormonal contraceptives have been implicated in sexual dysfunction among these women, the correlation lacks consistency across studies and varies between different types of hormonal contraception. This article assesses the available literature on the associations between various hormonal contraceptive methods and sexual function and provides practical management insights.

Over-the-counter access to hormonal contraception: a global perspective.

PURPOSE OF REVIEW: Oral contraceptive pills are among the most popular contraceptives worldwide, including among adolescents, and are available over the counter in over 100 countries. However, when a prescription is required, oral contraceptives may be difficult to obtain, particularly for adolescents. Recent approvals of over-the-counter progestin-only pills in the United Kingdom and United States have brought widespread attention to this topic. RECENT FINDINGS: Progestin-only pills, including the norgestrel pill recently approved for over-the-counter use in the United States, are highly effective and may be used safely without a prescription or medical monitoring, including by adolescents. These pills are associated with relatively high user satisfaction. Although over-the-counter availability may improve contraceptive access overall, issues related to insurance coverage and out-of-pocket cost may continue to pose practical barriers to access for many individuals. SUMMARY: Over-the-counter oral contraceptives are an appropriate and important contraceptive option for many adolescents. Over-the-counter availability has the potential to increase access to safe and effective contraception in the United States, United Kingdom, and other countries where a prescription is currently required. Future research on use patterns among adolescents is needed, as are advocacy efforts and policies to ensure access and affordability.

Effects of Hormonal Contraception and the Menstrual Cycle on Fatigability and Recovery From an Anaerobic Exercise Test.

ABSTRACT: Cabre, HE, Ladan, AN, Moore, SR, Joniak, KE, Blue, MNM, Pietrosimone, BG, Hackney, AC, and Smith-Ryan, AE. Effects of hormonal contraception and the menstrual cycle on fatigability and recovery from an anaerobic exercise test. J Strength Cond Res 38(7): 1256-1265, 2024-This study sought to evaluate the effects of oral contraceptive (OC) and hormonal intrauterine device (H-IUD) use, compared with a eumenorrheic (EUM) cycle, on fatigability and recovery between hormone the phases. Peak power (PP), average power (AP), fatigue index (FI), blood lactate, vessel diameter, and blood flow (BF) were measured from a repeated sprint cycle test (10 × 6 seconds) in 60, healthy, active women (mean ± SD ; age: 26.5 ± 7.0 years, BMI: 22.5 ± 3.7 kg·m -2 ) who used monophasic OC (≥6 months; n = 21), had a H-IUD (≥6 months; n = 20), or had regular naturally occurring menstrual cycle (≥3 months) or had a nonhormonal IUD (EUM; n = 19). Subjects were randomly assigned to begin in either the low-hormone phase (LHP) or high-hormone phase (HHP) and were tested once in each phase. Separate univariate analyses of covariances assessed the change from HHP to LHP between the groups, covaried for progesterone, with significance set at p ≤ 0.05. All groups demonstrated similar changes in PP, AP, FI, blood lactate, vessel diameter, and BF between the phases ( p > 0.05). Although not significant, AP was higher in LHP for OC (Δ -248.2 ± 1,301.4 W) and EUM (Δ -19.5 ± 977.7 W) and higher in HHP for H-IUD (Δ 369.3 ± 1,123.0 W). Oral contraceptive group exhibited a higher FI (Δ 2.0%) and reduced blood lactate clearance (Δ 2.5%) in HHP. In recreationally active women, hormonal contraception and hormone phases may minimally impact fatigue and recovery. Individual elite female athletes may benefit from understanding hormonal contraception type as performance and recovery may slightly vary across the cycle.

Implementation and perception of outpatient pharmacists prescribing hormonal contraceptives in North Carolina.

BACKGROUND: North Carolina (NC) House Bill 96, effective February 2022, enabled trained immunizing pharmacists across the state to prescribe hormonal contraceptives (HCs). However, the extent and barriers to deployment are unknown. The purpose of this study was to describe the uptake and challenges from outpatient pharmacists who trained to provide HCs in an outpatient practice to assist others in the implementation of this service. OBJECTIVES: The primary objective was to estimate the proportion of trained NC pharmacists who provided HCs in an outpatient setting. The secondary objective was to identify barriers during the implementation of this service. METHODS: This cross-sectional, anonymous, web-based survey was emailed on December 13, 2022, to NC-licensed pharmacists enrolled in the required training. A reminder email was sent on January 10, 2023, with all responses considered up to January 31, 2023. Pharmacists licensed in NC who performed at least 50% of their clinical practice in an outpatient setting were included. The primary endpoint was having prescribed HC (Y/N). All endpoints were analyzed using descriptive statistics. RESULTS: Of 1633 pharmacists eligible, 96 completed responses were included in the analysis (5.9%). Training was incomplete in 11 of 96 (11.5%), and 66 of 96 (68.8%) completed the training without implementing the service. Of the remaining 19 of 96 (19.8%) that developed a HC service, 15 of 96 (15.6%) had prescribed HCs. Among the 15 prescribing pharmacists, all reported positive patient feedback, while 7 reported improved job satisfaction. Among all 96 respondents, barriers reported included time constraints (49%) and a lack of appropriate reimbursement (43.8%). CONCLUSION: Few HC-trained NC outpatient pharmacists are prescribing HCs. Addressing prescribing barriers would potentially expand the scope of this service and further innovate the outpatient pharmacy setting.

Hormonal Contraception and Risk of Cardiometabolic Disease in Women with HIV.

Objective: We sought to determine the association of hormonal contraception (HC) and cardiometabolic outcomes among women with human immunodeficiency virus (HIV). Methods: We included women with HIV aged 18-45 years in clinical care in the Southeastern United States between 1998 and 2018. Oral and injectable HC use was captured from medication records. Our outcomes included incident cardiovascular/thrombotic disease (CVD) (atherosclerosis, hypertension, cerebrovascular disease, thrombosis, and heart failure) and incident metabolic disorders (diabetes, dyslipidemia, obesity, and non-alcoholic steatohepatitis). We excluded women with prevalent conditions. We used multivariable marginal structural models to examine time-varying current and cumulative HC use and cardiometabolic outcomes in separate analyses, adjusting for age, race, smoking, time-varying comorbidities, CD4 cell count, HIV RNA, and antiretroviral use. Women with HC exposure were compared with women without HC exposure. Results: Among the 710 women included, 201 women (28%) used HC. CVD analyses included 603 women without prevalent CVD and 93 incident events; metabolic analyses included 365 women without prevalent metabolic disease and 150 incident events. Current and cumulative oral HC use was associated with increased odds of CVD, though this was not statistically significant (adjusted odds ratio [aOR] = 2.08, [95% confidence interval (CI): 0.80-5.43] and aOR = 1.24 [95% CI: 0.96-1.60] per year of use, respectively). Oral HC was not associated with risk of incident metabolic disorders. Depot medroxyprogesterone acetate (DMPA) was not associated with risk of incident CVD. Current and cumulative DMPA use was significantly associated with decreased odds of incident metabolic disorders (aOR = 0.48 [95% CI: 0.23, 1.00] and aOR = 0.65 [95% CI: 0.42-1.00] per year of use, respectively). Conclusion: Our results suggest that cardiovascular risk should be considered when selecting contraception for women with HIV.

Abnormal Uterine Bleeding Associated With Hormonal Contraception.

Abnormal uterine bleeding is a common and bothersome symptom in people using hormonal contraception, and it can lead to discontinuation of reliable methods of contraception and unintended pregnancies. Clinicians should counsel individuals about the potential for abnormal bleeding at initiation of the contraceptive method. After considering and excluding other potential causes of abnormal uterine bleeding, clinicians can offer treatment options specific to each hormonal contraceptive method. This article includes algorithms to help clinicians treat abnormal uterine bleeding in people using levonorgestrel intrauterine devices, depo-medroxyprogesterone acetate, progestin implant, progestin-only pills, and combined hormonal contraception. For patients with levonorgestrel intrauterine devices, physicians should first ensure that the device is correctly placed within the uterus, then consider nonsteroidal anti-inflammatory drugs as a first-line treatment for abnormal uterine bleeding; estradiol can be used if nonsteroidal anti-inflammatory drugs are ineffective. For depo-medroxyprogesterone acetate or progestin implant users, combined oral contraceptives or nonsteroidal anti-inflammatory drugs may be considered. For patients using norethindrone progestin-only pills, changing to drospirenone progesterone-only pills may help reduce the bleeding. In people using combined hormonal contraception, it may be helpful to increase estrogen content from 20 mcg to 35 mcg per day, decrease the hormone-free interval (from seven to four or five days) in people using cyclic contraception, or start a trial of low-dose doxycycline. For continuous combined contraception users, adding a hormone-free interval of four or five days can help regulate bleeding patterns.

Patterns in the provision of government-subsidised hormonal postpartum contraception in Queensland, Australia between 2012 and 2018: a population-based cohort study.

BACKGROUND: Short birth intervals and unintended pregnancy are associated with poorer maternal and infant outcomes. There is a risk of pregnancy during the immediate postpartum period unless contraception is initiated. This retrospective cohort study aimed to capture the current patterns of hormonal contraceptive provision within 12 months postpartum in a high-income country. METHODS: We used a linked administrative dataset comprising all women who gave birth in Queensland, Australia between 1 July 2012 and 30 June 2018 (n=339 265 pregnancies). We described our cohort by whether they were provided with government-subsidised hormonal contraception within 12 months postpartum. The associations between hormonal postpartum contraceptive provision and demographic and clinical characteristics were examined using univariate and multivariate logistic regression and presented in terms of crude and adjusted odds ratios with 95% confidence intervals. RESULTS: A majority of women (60.2%) were not provided with government-subsidised hormonal postpartum contraception within 12 months postpartum. Women who were younger (<25 years), were overweight or obese, smoked, were born in Australia, were non-Indigenous, gave birth in a public hospital, or were in the lowest socioeconomic status group were more likely to be provided with postpartum contraception after adjusting for other covariates, compared with their counterparts. CONCLUSIONS: Strategies to increase the provision and uptake of contraception in the immediate postpartum period are needed to prevent short birth intervals and unintended pregnancy and ensure women's fertility intentions are enacted. Ongoing research is needed to examine the factors influencing women's access to contraceptive services and, further, the types of contraception provided.

Implementation of pharmacy access to hormonal contraception.

BACKGROUND: States throughout the country are enacting legislation to authorize pharmacist prescribing of hormonal contraception to decrease barriers to access. Little is known about the process of state implementation of pharmacist prescriptive authority for hormonal contraception. OBJECTIVES: To understand the state-level steps to enable pharmacist prescribing of hormonal contraception, including implementation challenges and facilitators. METHODS: We conducted a qualitative study of interviews with 18 key individuals, including pharmacists and other stakeholders, from ten states with laws permitting pharmacist-prescribed hormonal contraception from March 2021 to April 2022. We analyzed data using directed qualitative analysis principles and compared experiences across states. We organized the data using the Consolidated Framework for Implementation Research framework and evaluated relevant constructs in states' implementation efforts. RESULTS: Participants identified four key steps to implement pharmacist prescribing at the state level, including development of state rules and regulations, educational programs, reimbursement mechanisms, and expansion strategies to pharmacists and pharmacies. Participants identified early involvement of key stakeholders and a culture of support for clinical pharmacists as facilitators to implementation. Challenges included complexity and cost of billing mechanisms, lack of funding for implementation efforts, and competing priorities of pharmacies/pharmacists. CONCLUSION: Participants in states with pharmacist prescriptive authority for hormonal contraception identified development of reimbursement and billing mechanisms as the most critical state-level step in implementation. Focusing on facilitators of key steps can guide states in developing successful implementation strategies to improve contraceptive access.

The impact of tirzepatide and glucagon-like peptide 1 receptor agonists on oral hormonal contraception.

BACKGROUND: Tirzepatide is a dual glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor agonist (RA) whose mechanism of action leads to a greater effect of gastric emptying (GE) than typical GLP-1 RAs. After the first dose of tirzepatide, GE is most substantially delayed. The drug then undergoes tachyphylaxis after subsequent doses. Although data on GLP1-RAs have historically demonstrated a lack of impact on bioavailability of oral hormonal contraceptives, manufacturer recommendations for tirzepatide indicate an interaction exists. OBJECTIVES: The objectives of this literature review were to review trial data on differences in the impact of tirzepatide and GLP-1 RAs on oral hormonal contraceptives and provide an analysis of safety data between oral contraceptives and incretin agents. METHODS: PubMed and Google Scholar were searched using the generic name for the GLP-1/GIP agent, the generic names for GLP-1 RAs and hormonal contraceptives, followed by the generic names plus the interacting medication. A total of 6 clinical trials were selected for inclusion in the literature review. RESULTS: Of the 6 articles included in the review, one investigated the use of tirzepatide and showed a statistically significant reduction in area under the plasma drug concentration-time curve, maximum concentration, and time to maximum plasma concentration when tirzepatide was concomitantly administered with an oral hormonal contraceptive. The remaining 5 studies involving GLP-1 RAs did not show a statistically or clinically significant difference of impact of the agents on oral hormonal contraceptives. CONCLUSION: It could be suggested that tirzepatide had a greater impact on absorption of oral hormonal contraceptives than other GLP-1 RAs. The rapid dose escalation and greater delay on GE enhanced the impact on oral medications such as contraceptives. This differed from other GLP-1 RAs and creates a unique need for enhanced provider and patient education regarding the management of this interaction and future studies to evaluate this interaction further.

Characteristics and hormonal contraception use patterns of levonorgestrel 13.5 mg intrauterine device users in Sweden 2014-2016.

OBJECTIVES: The levonorgestrel-releasing intrauterine device containing 13.5 mg of levonorgestrel (LNG 13.5 mg IUD), Jaydess, was approved for contraception by the European Medicines Agency in 2013. We aimed to describe the characteristics of new users of LNG 13.5 mg IUD in Sweden within the first 3 years after approval (2014-2016). STUDY DESIGN: We conducted an observational, population-based study using data from the Swedish national registers. Women with the first pharmacy dispensation of LNG 13.5 mg IUD between 2014 and 2016 were followed until December 31, 2020. Descriptive analyses included demographic characteristics, duration of the use of first-time LNG 13.5 mg IUD, and contraceptive switching patterns. RESULTS: We included 38,327 women, with mean age at first-time LNG 13.5 mg IUD use of 26 (SD: 7) years. Over 80% were prescribed LNG 13.5 mg IUD by a midwife. The most common comorbidities in the year prior to LNG 13.5 mg IUD use (2%-3% prevalence) were depression, anxiety, premenstrual syndrome, and menorrhagia. The median duration of first-time LNG 13.5 mg IUD use was 2.6 years, and after use, more than 50% of women opted to continue using a hormonal intrauterine device. CONCLUSIONS: In this postmarketing drug utilization study, there were over 38,000 first-time LNG 13.5 mg IUD users in Sweden between 2014 and 2016, with an estimated median duration of use of 2.6 years. First-time LNG 13.5 mg IUD users consisted mostly of young, healthy individuals with a history of hormonal contraceptive use. Over half of the women continued using a hormonal IUD after the first LNG 13.5 mg IUD. IMPLICATIONS: The median duration of LNG 13.5 mg IUD use was 2.6 years, approaching the 3-year indicated use limit. The majority of users continued with another hormonal intrauterine device after LNG 13.5 mg IUD use.

Comparison of estrogenic components used for hormonal contraception.

Attempts have been made over the years to replace ethinyl estradiol (EE) in combined oral contraceptives (COCs) with the less potent natural estrogen estradiol (E2), or its prodrug, E2 valerate (E2V), to improve their safety and tolerability. Recently, a COC incorporating a novel weak natural estrogen, estetrol (E4), combined with drospirenone, has become available. We present a comparative analysis of the three prevailing estrogens used in COCs, focusing on their structure-function relationships, receptor-binding affinity, potency, metabolism, pharmacokinetic parameters, and pharmacodynamics. The binding affinity of EE to estrogen receptor (ER)α is twice that of E2, whereas its affinity for ERß is about one-half that of E2. E4 has a lower binding affinity for the ERs than E2. The high potency of EE is notable in its dramatic increase in estrogen-sensitive hepatic globulins and coagulation factors. EE and E2 undergo extensive and comparable metabolism, while E4 produces only a very limited number of metabolites. E4 has the highest bioavailability among the three estrogens, with E2 having <5%. Studies demonstrate consistent ovulation inhibition, although a higher dose of E4 (15 mg) in COCs is required to achieve follicular suppression compared to E2 (1-3 mg) and EE (0.01-0.035 mg). E2 and E4 in COCs may be less stimulatory of coagulant proteins than EE. Studies with E2/dienogest suggest a comparable risk of venous thromboembolism to EE/levonorgestrel, while data assessing risk with an E4-based COC are insufficient. Nevertheless, the E4-based formulation shows promise as a potential alternative to EE and E2 due to its lower potency and possibly fewer side effects.

A Perspective on Hormonal Contraception Usage in Central Nervous System Injury.

Naturally occurring life stages in women are associated with changes in the milieu of endogenous ovarian hormones. Women of childbearing age may be exposed to exogenous ovarian hormone(s) because of their use of varying combinations of estrogen and progesterone hormones-containing oral contraceptives (OC; also known as "the pill"). If women have central nervous system (CNS) injury such as spinal cord injury (SCI) and traumatic brain injury (TBI) during their childbearing age, they are likely to retain their reproductive capabilities and may use OC. Many deleterious side effects of long-term OC use have been reported, such as aberrant blood clotting and endothelial dysfunction that consequently increase the risk of myocardial infarction, venous thromboembolism, and ischemic brain injury. Although controversial, studies have suggested that OC use is associated with neuropsychiatric ramifications, including uncontrollable mood swings and poorer cognitive performance. Our understanding about how the combination of endogenous hormones and OC-conferred exogenous hormones affect outcomes after CNS injuries remains limited. Therefore, understanding the impact of OC use on CNS injury outcomes needs further investigation to reveal underlying mechanisms, promote reporting in clinical or epidemiological studies, and raise awareness of possible compounded consequences. The goal of the current review is to discuss the impacts of CNS injury on endogenous ovarian hormones and vice-versa, as well as the putative consequences of exogenous ovarian hormones (OC) on the CNS to identify potential gaps in our knowledge to consider for future laboratory, epidemiological, and clinical studies.

Pharmacist furnishing of hormonal contraception in California's Central Valley.

BACKGROUND: In the United States, more than 19 million people of reproductive age need access to publicly funded hormonal contraception or live in areas where it is not readily available. These include rural areas of the country, commonly known as contraception deserts. Pharmacist prescribing has been proposed to increase access, but little is known about its implementation in such areas. OBJECTIVE: This study quantified the extent of pharmacists' furnishing (prescribing) of hormonal contraception in California's Central Valley community pharmacies and identified barriers and facilitators to implementation. METHODS: The researchers conducted a cross-sectional, mixed methods, observational study by (1) contacting all community pharmacies in the 11 counties of the Central Valley to determine furnishing rates and (2) surveying and interviewing pharmacies that indicated they furnished hormonal contraception. RESULTS: Overall, 13% of pharmacies within the Central Valley reported that they furnished hormonal contraception. Pharmacists reported that barriers to furnishing included costs to patients and the pharmacy, lack of time and staff, lack of training and certifications, limited patient awareness of pharmacists' ability to furnish, pharmacists' limited confidence in furnishing, and patient use of emergency contraception as an alternative to hormonal contraception. Pharmacists reported that patients often sought hormonal contraception from pharmacists owing to ease of accessibility to a pharmacist; some other facilitators included advertising, confidentiality, low cost to patients, and referrals from other providers. CONCLUSIONS: Common barriers were identified across pharmacies that furnished hormonal contraception, indicating the need for strategies that reduce these barriers to help expand patient's access to these services and to increase pharmacists' ability and confidence to prescribe.

Maternal use of hormonal contraception and risk of childhood autism spectrum disorders: A Parental Exposures and Child Health (PECH) cohort study.

A recent hypothesis suggests that maternal hormonal contraception use has contributed to the increasing incidence of autism spectrum disorders (ASD). We used a nationwide population-based cohort (the PECH cohort) including 1,056,149 Danish children born in the period January 1, 1998, to December 31, 2014, to assess associations between maternal hormonal contraception use and childhood ASD (end of follow-up: December 31, 2017). Maternal hormonal contraception use was grouped as "recent use" (≤ 3 months before pregnancy start or during pregnancy), "previous use" (>3 months before pregnancy start) and "never use", except for few products. Incidence rate ratios (IRRs) were estimated using Poisson regression. During follow-up of nearly 12 million person-years, 19,996 children were diagnosed with ASD. A slightly higher IRR was observed for maternal recent use of any hormonal contraception, compared to previous use. This association was largely driven by the non-oral progestin-only products, and associations were especially seen for infantile autism and other/unspecified ASD. An increased IRR of infantile autism was also observed for recent use of the oral progestin-only products, compared to previous use. Our results suggest that maternal use of hormonal contraception may be associated with ASD risk in children, especially for the progestin-only products.

Hormonal contraception for female athletes presents special needs and concerns.

PURPOSE: Oral contraceptives (OCs) are commonly used by female athletes raising concerns regarding the possible adverse effects of OCs on physical performance, musculoskeletal injuries, and bone density. We aimed to review all current studies on the physiological effects of OCs in physically active women. MATERIALS AND METHODS: A review of literature in electronic search in PubMed and Google Scholar databases from December 2002 to December 2022 using relevant keywords. The reference lists of the articles found eligible were also reviewed. RESULTS: Out of 344 articles in the initial database, 54 clinical studies were eligible for inclusion in our literature review. OCs are used by about two-thirds of female athletes. Current research suggests that OCs' effects on endurance performance and muscle strength are mostly reassuring. OCs do not seem to have a major negative impact on bone health or sports injuries. In fact, new data suggests that they may even significantly reduce the risk of anterior cruciate ligament (ACL) injury. CONCLUSIONS: OCs can be safely used by young female athletes, who may also benefit from better menstrual cycle control. OCs offer newly realised protection from ACL injuries. The use of OCs must be carefully individualised according to their preferences, expectations, and experience.

Hormonal contraception can be safely prescribed to active women. The International Olympic Committee advocates a new and wider definition for the 'athlete triad', where low energy availability presents a special challenge for these athletes. New data suggests that the use of oral contraceptives may protect against ACL injury.

Vaginal microbiome, antiretroviral concentrations, and HIV genital shedding in the setting of hormonal contraception initiation in Malawi.

OBJECTIVE: The aim of this study was to understand how vaginal microbiota composition affects antiretroviral concentrations in the setting of hormonal contraception initiation. METHODS: Cervicovaginal fluid (CVF) concentrations of tenofovir, lamivudine, and efavirenz from 73 Malawian women with HIV were compared before and after initiation of depot-medroxyprogesterone acetate (DMPA) or levonorgestrel implant. We evaluated antiretroviral concentrations and vaginal microbiota composition/structure in the context of contraception initiation and predicted genital shedding using multivariable repeated measurements models fit by generalized estimating equations. RESULTS: Mean lamivudine CVF concentrations decreased 37% 1 month after contraception initiation. Subgroup analyses revealed a 41% decrease in women 1 month after initiating levonorgestrel implant, but no significant difference was observed in DMPA group alone. Tenofovir, lamivudine, and efavirenz CVF concentrations were positively correlated with anaerobic bacteria associated with nonoptimal vaginal microbiota. Risk of genital HIV shedding was not significantly associated with tenofovir or lamivudine CVF concentrations [tenofovir relative risk (RR): 0.098, P = 0.75; lamivudine RR: 0.142, P = 0.54]. Lack of association between genital HIV shedding and efavirenz CVF concentrations did not change when adjusting for vaginal microbiota composition and lamivudine/tenofovir CVF concentrations (RR: 1.33, P = 0.531). CONCLUSION: No effect of hormone initiation on genital shedding provides confidence that women with HIV on either DMPA or levonorgestrel implant contraception will not have compromised ART efficacy. The unexpected positive correlation between antiretroviral CVF concentrations and certain bacterial taxa relative abundance requires further work to understand the mechanism and clinical relevance.
