This study found that testosterone is converted to estrogenic steroids in vitro without aromatase involvement, suggesting that combining 5α-reductase and aromatase inhibitors might reduce estrogenic steroids more completely in vivo.

This study found that estrogen can cause reversible suppression of the hair cycle by inducing premature catagen and maintaining the telogen phase without damaging the hair follicle stem cell niche or the signature gene expressions of dermal papilla cells.

In this study, prolonged systemic administration of 17β-estradiol in castrated male mice delayed wound healing by inhibiting re-epithelialization and reducing collagen accumulation, with estrogen receptor-α likely mediating this effect.

The document concludes that identifying the cause of amenorrhea is crucial for proper treatment.

This report describes a case of meningioma in a transwoman treated long-term with estradiol and cyproterone acetate, suggesting possible concern over female sex steroids and meningioma risk.

This review examines the scientific evidence on the short-term safety of testosterone therapy for treating hypoactive sexual desire disorder in women, without presenting new clinical results.

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 study suggests that lower-dose ethinyl estradiol formulations and progestin-only contraceptives may offer safer options for managing PCOS in obese women due to minimal metabolic effects.

This article discusses the various roles of steroids in vertebrate organ systems and notes several glucocorticoids that were among the Top 200 Drugs by sales in the 2010s, but it reports no new clinical findings.

This review discusses the role of physical activity in healthy aging and reports no clinical results; the authors emphasize the need for integrating exercise into daily life and social settings.

This study found that SNPs in the MVK, ARPC1B, and CA2 genes may indicate a genetic predisposition for severe acne related to steroidogenesis.

This review examines the development of cardiovascular risk factors related to testosterone levels in PCOS women and reports no new clinical results.

Testosterone reduces, while finasteride enhances, morphine's pain relief.

This review discusses the pathophysiology, diagnosis, and management of functional hypothalamic amenorrhea in adolescent girls and reports no new clinical results.

This study found that 17-beta-estradiol inhibits hair growth in mice by blocking hair follicles in the telogen phase, whereas an estrogen receptor antagonist promotes hair growth by initiating anagen.

This review discusses the effects of estrogen on skin and reports no new clinical results; it highlights estrogen's potential benefits on skin thickness, collagen quality, and hair follicle life cycle.

This study identified changes in transcription factor gene expression across various signaling pathways during inner ear hair cell regeneration in birds, revealing patterns and potential new pathways for future investigation.

This article discusses the potential effects of exogenous testosterone, highlighting that its impact on prostate cancer progression, cardiovascular health, and behavior remains uncertain and needs further investigation.

This article reviews current evaluation and treatment options for androgenic alopecia in women and reports no new clinical results.

This review discusses the use of hair analysis for examining stress and reproduction hormone levels in wildlife and highlights the need for more comprehensive physiological validations across species.

This review discusses the unique dermatologic needs of transgender individuals during transitioning and emphasizes the importance of accommodating care in medical settings; it reports no new clinical results.

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.

This study in male mice found that testosterone provides strong protection against skin necrosis after ischemia, working through its estrogenic and androgenic derivatives to enhance skin survival and revascularization, with 17β-estradiol being notably more effective than dihydrotestosterone.

This review discusses the role of androgen hormones in the pathophysiology of childhood androgenetic alopecia and reports no clinical results.

This study found that exposure to phytoestrogens, bisphenol A, parabens, and phthalates was associated with developing idiopathic premature thelarche in girls.

This study found that administering testosterone increased the expression of sexual behavior and elevated serum testosterone and DHT levels in female capuchin monkeys, hinting at potential insights into testosterone use and its risks in humans.

This study found that among patients with sex cord stromal ovarian tumors, 11% exhibited signs of virilization, requiring thorough clinical evaluation to rule out non-neoplastic causes.

This article reviews the effects of various medications on male fertility, noting that while commonly used drugs can mostly have reversible impacts, conclusive human evidence remains limited.

This review discusses sex differences in the neuroendocrine response to stress, focusing primarily on rodent studies, and highlights open questions about the roles of gonadal hormones and sex chromosomes.

In this study, BPA rapidly increased dendritic spine and synapse densities in cultured rat hippocampal neurons, with involvement of estrogen receptors and ERK1/2 and p38 pathways, but disrupted dihydrotestosterone's effects on synaptic plasticity.
