This study found that nestin-expressing unipotent progenitor cells capable of differentiating into outer root sheath keratinocytes are present during hair follicle development and in adult hair follicles.

This review examined studies on erectile dysfunction and 5 alpha-reductase inhibitors, concluding that these drugs do not significantly cause erectile dysfunction and emphasizing testosterone's importance over dihydrotestosterone in erectile function.

In this study, the aqueous extract from Phthirusa pyrifolia leaves significantly decreased testosterone levels in male Wistar rats without causing liver or kidney damage, suggesting potential effects on libido and reproduction.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

This study found that testosterone may promote glioblastoma progression by being converted into dihydrotestosterone, which enhances cell proliferation, migration, and invasion in GBM cell lines.

This article reviews the clinical and biochemical features of genetic mutations affecting dihydrotestosterone production and their potential role in male pseudo-hermaphroditism, but presents no new clinical results.

This review covers cell transplantation methods for genitourinary reconstruction, discussing tissue sources and complications but presenting no new clinical findings.

This article explores the dynamic and energy-efficient nature of telogen hair follicles, challenging the notion of dormancy, and highlights their potential in advancing treatments for hair growth disorders.

This case report describes a 72-year-old woman with a steroid cell tumor of the ovary, highlighting the critical role of imaging, biochemical evaluation, and pathology in diagnosing and managing hormonally active ovarian tumors that cause virilization in postmenopausal women.

In this study, flutamide at therapeutic doses caused significant histological changes in the testes and epididymis of adult albino rats, reducing androgen receptor immunoreactivity and increasing estrogen receptor immunoreactivity.

This review examines the role of nerves in regeneration across various species and discusses their importance as components in the progenitor cell niche, reporting no new clinical results.

Environmental factors and exposure to toxins may contribute to male infertility by affecting sperm and hormone function.

This review discusses the current understanding of androgen biosynthesis, mechanisms of action, and their roles in human biology, as well as related congenital and acquired disorders, but it reports no new research findings.

This study concludes that anti-androgenic chemicals causing short anogenital distance in male fetuses also induce a feminized transcriptional profile in the perineum, implicating Wnt and estrogen signaling in the process.

This study found that low doses of bisphenol A may increase proliferation of the ventral prostate in adult rats by altering the estrogen to androgen ratio and gene expression.

This study found that finasteride treatment in male rats may lead to changes in connexin 43 expression in the testes of their offspring, potentially affecting spermatogenesis.

This case report describes a post-menopausal woman with severe hirsutism whose high testosterone levels decreased after gonadotropin suppression, indicating residual hormone-producing tissue responsive to gonadotropins.

In this study, researchers found that high doses of rosemary extract given to lactating mother rats adversely affected their offspring, causing weight issues and damage to liver, kidney, and testis tissues, suggesting potential teratogenic risks if used during human pregnancy and lactation.

This review discusses recent advancements in understanding and managing congenital adrenal hyperplasia, including improvements in screening, diagnostics, and potential genetic and cell-based treatments, but reports no new clinical findings.

This study found a significant association between patients' sex of rearing and external genitalia in those with gonadal dysgenesis, while noting lower testosterone levels compared to controls.

This special issue contains abstracts from the ASA 40th Annual Meeting, providing an overview of various studies without reporting new primary results.

This review examines experimental and clinical evidence on PDRN, a drug derived from salmon DNA that acts via the adenosine A2A receptor and shows promise for tissue repair and treatment of diabetic foot ulcers in regenerative medicine.

In this study, the authors concluded that COVID-19 may not cause direct long-term harm to testicular function, but temporary indirect effects could occur, suggesting a possible delay in pursuing parenthood post-recovery.

This article discusses the role of growth hormone, insulin, and IGF-1 in acne development and highlights how diet and syndromic evidence support their involvement, but presents no new clinical findings.

This review examines the role of androgens and androgen receptors in regulating glucose and lipid metabolism, focusing on their effects on mitochondrial content and function; it also discusses the sex-dimorphic influence of androgens and provides theoretical insights into their mechanisms.

This review discusses the impact of COVID-19 on the endocrine system and reports no clinical results; the authors emphasize the need to investigate endocrine damage during and after COVID-19 infection.

This review discusses how COVID-19 may affect gonadal function and potential gender differences, but reports no clinical results; it highlights possible mechanisms and new treatment approaches from recent literature.

This chapter discusses the sources, classifications, and effects of hormones, their role in disease treatment and food security, and reports no new results.

This study concluded that among men with normal testosterone levels, a small increase in serum dihydrotestosterone may reduce symptoms of hypogonadism, suggesting its potential diagnostic use after ruling out hypogonadism.

This research found that Leydig cells significantly rely on synthesizing omega-6 HUFAs to support male steroid hormone production, highlighting a new role for these fatty acids in the male reproductive system.
