This review discusses the effects and selection criteria of different progestogens in various treatments but reports no direct clinical comparisons of their metabolic effects.

This case report suggests that the progestogen-only pill may cause false-positive aldosterone/renin ratio results in primary hyperaldosteronism screening, indicating it should be omitted before testing.

This study found that feeding norethindrone acetate to albino rats over two years caused various dose-related health effects, such as growth retardation and liver changes, but did not increase overall tumor incidence.

This study suggests that the testosterone analogs 7α-Methyltestosterone and 7α-Ethyltestosterone may offer promising androgenic, progestogenic, and anabolic properties for development as male contraceptives.

This study found that in non-obese women with moderate body hair growth, DHEA-S and prolactin levels were higher, and SBP was lower compared to controls, which may inform treatment decisions.

This review discusses the pharmacological properties of progestins used in contraception and hormone replacement therapy, focusing on drospirenone's unique effects, but reports no new experimental findings.

5α-reduced progestogens may reduce mood issues and brain damage linked to HIV-1 Tat.

This study found that while ethinyl oestradiol and cyproterone acetate effectively treated hirsutism in 90% of patients, 80% experienced relapse within six months after stopping treatment, suggesting long-term use is necessary.

In this study, inhibiting the formation of 5α-reduced steroids in pregnant rats shortened gestation time, reduced litter size, and impaired cognitive and neuroendocrine function in their juvenile offspring.

This study found that hair products commonly used by Black women exhibited hormonal activity, which could impact health outcomes and contribute to health disparities.

This review discusses the regulation of hair growth, causes of excessive androgen secretion, and current safe solutions for hyperandrogenism manifestations in women but reports no new clinical results.

This review discusses the histology of pilo-sebaceous follicles, androgen receptors, and various treatments for hirsutism and acne in women, but it reports no new clinical results.

This article reviews the discovery and various physiological effects of cyproterone acetate, reporting its established indications for several androgen-driven conditions but providing no new clinical data.

This review discusses the diagnosis, management, and hormone treatment of transsexual individuals, and examines the risks and effects of cross-sex hormone therapy without presenting new clinical results.

This review discusses hormone replacement therapy for women with premature ovarian insufficiency, strongly recommending it for symptom relief and bone protection, but notes a lack of evidence on optimal types and doses.

This article provides a comprehensive overview of polycystic ovary syndrome, its diagnosis, complications, and symptom-focused management options, but does not present new clinical findings.

This study reports that diffuse alopecia of the scalp developed in some women during or after using oral contraceptive drugs, suggesting a potential link between the medication and hair loss.

In this study, researchers found that human ovaries at different life stages biosynthesize both canonical and non-canonical steroid hormones, with fetal ovaries showing higher enzyme activity related to estradiol and testosterone conversion compared to adult tissues.

This study describes a new method using high-resolution mass spectrometry for analyzing multiple steroids in human scalp hair, with newborn hair showing the highest steroid concentrations among examined age groups.

This study reports that among young women, combined oral contraceptives containing chlormadinone, among others, are associated with an increased risk of venous thromboembolism compared to those containing levonorgestrel with low ethinylestradiol.

The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.

This case report describes a woman who developed a 5 cm patch of scalp hair loss four months after receiving an Implanon contraceptive implant, with no previous history of hair loss or scalp issues.

This source highlights the role of progestin in contraception, noting that while different types have varying progesteronic potential and effects, they share similar contraceptive mechanisms, allowing tailored use based on patient conditions.

Different drugs are used to manage breeding, prevent or end pregnancy, and treat reproductive issues in dogs and cats.

The document suggests improvements for a hair and scalp disease book and recommends a two-volume skin surgery reference for dermatologists.

This review discusses the pharmacological properties and clinical applications of cyproterone acetate and similar antiandrogens, noting previous failures in local applications due to concentration limitations; it reports no new empirical results.
