Hormone free contraception

OBJECTIVE: To characterise and compare the toxicity of estetrol (E4) and 17α-ethinylestradiol (EE2), and their respective mixture with the progestin drospirenone (DRSP) in zebrafish (Danio rerio) embryos. METHODS: Zebrafish embryos were exposed to E4, EE2, DRSP, E4+DRSP, and EE2+DRSP in a fish embryo acute toxicity (FET) test. A second test examined behavioural responses and, using label-free proteomics, identified changes in protein expression in response to hormonal treatments, across a range of concentrations, including those that are considered to be environmentally relevant...

BACKGROUND: In this study we shed light on ongoing trends in contraceptive use in Flanders (Belgium). Building on the fundamental cause theory and social diffusion of innovation theory, we examine socio-economic gradients in contraceptive use and the relationship to health behaviours. METHODS: Using the unique and recently collected (2020) ISALA data, we used multinomial logistic regression to model the uptake of contraceptives and its association to educational level and health behaviour (N:4316 women)...

OBJECTIVES: To assess women's contraceptive preferences in the immediate postpartum period and identify factors associated with use of their desired contraceptive method six months later. MATERIAL AND METHODS: This prospective cohort study included women ≤48 h after delivery at a single public Brazilian hospital. The women's interview took place in two different momentsbefore hospital discharge (in-person interview) and six months after delivery (by telephone contact)...

The cyclical changes in sex hormones across the menstrual cycle (MC) are associated with various biological changes that may alter resting metabolic rate (RMR) and body composition estimates. Hormonal contraceptive (HC) use must also be considered given their impact on endogenous sex hormone concentrations and synchronous exogenous profiles. The purpose of this study was to determine if RMR and dual-energy X-ray absorptiometry body composition estimates change across the MC and differ compared with HC users...

PURPOSE: To correlate the sexual desire levels with sexual hormone binding globulin and free androgen index in women taking different types of hormonal contraceptives (HCs) containing ethinylestradiol (EE), oestradiol valerate (E2V), 17β-oestradiol (E2), or estetrol (E4), combined or in phasic formulation with different progestogens having antiandrogenic properties. METHODS: Three hundred and sixty-seven women (age range 18-46) participated in the study. SHBG and total testosterone (TT) were measured, and the Free Androgen Index (FAI) was calculated...

INTRODUCTION: Sexual side effects of combined oral contraceptives (COCs) have not been fully understood, but increasing evidence prompts broader risk/benefit evaluation and merits inclusion in counseling on contraceptive options. OBJECTIVES: The study sought to explore the impact of combined estrogens-progestin oral contraceptives on components of female sexuality, including sexual desire, anatomic genitourinary changes, lubrication, orgasm, provoked vestibulodynia, well-being, body image, partner preference, and relationship stability...

BACKGROUND: Robust information on relative effects of hormonal contraceptives on endogenous androgens is important for understanding beneficial and adverse effects, method choice and development of new methods. METHODS: In this ancillary study at the East London, South Africa site of the ECHO multicentre randomized trial, we compared effects of three contraceptive methods on serum androgen levels among contraceptive users aged 18 to 35 years. Participants were allocated by centrally-managed randomization to open label depot medroxyprogesterone acetate (DMPA-IM), copper intrauterine device (IUD) or levonorgestrel implant...

The aim of our article is to discuss barriers associated with post-pregnancy contraception in Brazil during the SARS-CoV-2 (COVID-19) pandemic. Socioeconomic differences in gaining access to long-acting reversible contraceptive (LARC) methods became greater during the COVID-19 pandemic. The inadequate distribution of existing resources and the reduced capacity for elective care meant that healthcare providers in family planning had to be reallocated to respond to COVID-19 emergencies. In Brazil, 74% of the population depends on the national health service (Sistema Unico de Saúde) including for the provision of free 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...

OBJECTIVES: Ovaprene is a novel, investigational, intravaginal hormone-free monthly ring contraceptive designed for use in women of reproductive age to be worn over multiple weeks (one menstrual cycle). The objective of this work was to evaluate the safety of Ovaprene during a nine-month repeat-dose sheep study. STUDY DESIGN: In addition to traditional safety endpoints such as histopathological evaluation of the sheep female reproductive tract, vaginal fluids were collected and tested for released iron over time...

BACKGROUND: Vitamin D (Vit D) deficiency has been linked to symptoms of polycystic ovary syndrome (PCOS), yet little is known about Vit D supplementation as a treatment for sexual dysfunction (SDy) in women with PCOS. AIM: To explore the implications of serum total 25-hydroxyvitamin D (25[OH]D) and bioavailable 25[OH]D (bio-25[OH]D) status and replacement on women with PCOS and SDy. METHODS: Reproductive-age women with PCOS who were not desiring fertility were eligible provided that they also had SDy, as assessed by the Female Sexual Function Index (FSFI), and were without severe depression, as evaluated by the Beck Depression Inventory II (BDI-II)...

Female sterilization via fallopian tube ligation is a common procedure. However, after the operation, over 10% of women seek re-fertilization, which is frequently unsuccessful. In addition, there is evidence that fallopian tubes contribute to the spread of endometriotic tissue as they serve as channels for proinflammatory media entering the abdominal cavity via retrograde menstruation. Here, we present stimuli-degradable hydrogel implants for the functional, biocompatible, and reversible occlusion of fallopian tubes...

BACKGROUND: Delivering contraceptive hormones through a transdermal patch or a vaginal ring might have advantages over the traditional oral route. OBJECTIVES: To compare the effectiveness, compliance, and side effect profile of oral and parenteral drug administration methods. METHODS: We performed a systematic literature search in four medical databases-MEDLINE (via PubMed), Cochrane Library (CENTRAL), Embase, and Scopus-from inception to 20 November 2022...

CONTEXT: There are no reported data from prospective long-term studies on the relation of androgen levels in young women with development of metabolic syndrome (MetS) before menopause. OBJECTIVE: We investigated associations of androgens and SHBG with incident MetS during 23 years of follow-up. METHODS: We included 366 White and 375 Black women ages 20 to 32 years participating in the CARDIA study and CARDIA Women's study, free of MetS at baseline examination (1987-1988), and premenopausal 23 years later...

OBJECTIVE: To determine the proportion of participants whose uterine bleeding/spotting was interrupted for at least seven days during the month after they received a combined hormonal injection. We also evaluated bleeding at 21 days and 12 weeks after the injection. STUDY DESIGN: We conducted a randomized, double-blind, placebo-controlled trial in 46 contraceptive implant users who presented with bothersome uterine bleeding/spotting. A single dose of a combination injectable contraceptive or placebo was administered intramuscularly at enrollment...

BACKGROUND: People in Western countries are increasingly rejecting hormone-based birth control and expressing a preference for hormone-free methods. Digital contraceptives have emerged as nonhormonal medical devices that make use of self-tracked data and algorithms to find a user's fertile window. However, there is little knowledge about how people experience this seemingly new form of contraception, whose failure may result in unwanted pregnancies, high health risks, and life-changing consequences...

PURPOSE: Progestin-only pills (POPs), compared to combined, are not associated with an increased risk of venous thromboembolism, but are associated with a poor cycle control. The aim of this study was to evaluate the impact of a new POP [4 mg drospirenone (DRSP) for 24 days with a 4-day hormone-free interval] on some coagulation markers (both procoagulant and fibrinolytic) and to describe its impact on bleeding patterns. MATERIALS AND METHODS: This is a prospective trial, based on serum evaluation of following coagulation markers and tests: Factor (F) X, F VIII, F V, INR, aPTT, Protein S and antithrombin III...

The transgender community is rapidly growing, necessitating further education and understanding of their unique healthcare needs. Gender affirmation is a multistep process, which generally begins with transgender individuals socially transitioning by adopting a new name, pronouns, and appearance changes, such as hair and clothing, to express themselves. Additional gender affirmation treatment can be achieved through medical therapy with hormones and surgical intervention. Here, we report the case of an 18-year-old transgender man who presented to his primary care provider for a referral to initiate a medical transition with testosterone therapy...

BACKGROUND: Provider bias is a main barrier that extensively violates the right of free family planning method choice. Egypt is one of the countries that shows skewness in its method mix. Provider bias and insufficiency of alternative methods are identified as potential factors underlying this phenomenon which contributes to high unmet needs and discontinuation rates. Provider bias may be influenced by cultural beliefs and societal trends and is usually overlooked as a possible cause of this skewed method mix...

BACKGROUND: The incidence of breast cancer among women under 41 years old varies worldwide, with higher rates observed in developing countries. These young women often face later-stage diagnoses. In this study, we examine a cohort of young women who were treated for breast cancer in São Paulo, Brazil. METHODS: We conducted a retrospective cohort study involving women under 41 years old. Our objective was to describe patient and treatment characteristics, with the main outcomes being overall and disease-free survival...
