This article reviews the potential clinical use of anabolic steroids in treating muscle loss from chronic diseases and aging and highlights both the benefits and risks of these substances in sports.

This article reviews the coordination of the hypothalamic-pituitary-gonadal axis, male fertility, and therapies for hypogonadism, but reports no new clinical findings.

This article reviews the congenital disorder aphallia, describing its rarity, clinical characteristics, and the normal hormonal and chromosomal profiles of affected individuals, but does not report new research findings.

This study revealed that nestin-expressing progenitor cells capable of becoming ORS keratinocytes are present during both hair follicle development and in adult hair follicles.

This study suggests that synthetic steroid analogues or 5α-reductase modulation could be potential therapeutic strategies for nervous system disorders, but further research on their effects is necessary.

This chapter discusses charnolopharmacotherapeutics for various medical conditions and suggests antioxidant-loaded nanoparticles may improve treatment by enhancing central nervous system delivery and inducing charnolophagy.

The researchers suggest that testosterone levels might influence COVID-19 susceptibility and severity, with low levels potentially protecting against infection but possibly worsening severe disease due to cytokine storm activation.

This study reviews the mechanisms by which SARS-CoV-2 may impact male fertility, noting potential disruptions in spermatogenesis and hormone secretion, and underscores the need for follow-up in recovered men.

Pharmacists play a crucial role in improving patient outcomes through personalized care and staying updated with scientific advancements.

This study suggests that extracellular vesicles from prostate cancer cells could aid in identifying tumor heterogeneity and serve as biomarkers, while also playing a role in SARS-CoV-2 infection in nasopharyngeal mucus.

In this study, high doses of Lepidium sativum seeds extract were reported to cause toxicity and tissue damage in animals, suggesting the need for careful use under medical supervision.

This review discusses the role of neurosteroids and androgens throughout different life stages, noting the potential disruptions caused by 5α-reductase inhibitors like finasteride, but no new clinical results are reported.

This review discusses how sex hormone levels and local steroid synthesis influence gender differences in aging skin, reporting no new clinical results.

This review highlights potential negative impacts of certain medications on male fertility, such as hormonal disruption and germ cell toxicity, emphasizing the importance of clinicians being aware of these effects to advise on safer alternatives.

This review discusses the role of anti-Müllerian hormone in polycystic ovary syndrome and its male equivalent, but reports no new clinical findings; it suggests further investigation is needed into male relatives' reproductive function.

This review discusses the role of skeletal muscle in synthesizing bioactive androgens, highlighting that intramuscular androgens may influence muscle via intracrine action, but their precise function remains unclear.

This review highlights that various commonly prescribed medications for chronic conditions may impact male fertility by affecting hormone secretion, sperm production, ejaculation, erectile function, and libido, although conclusive evidence is limited to specific drug groups.

In a laboratory study, Grateloupia elata extract demonstrated antioxidant and anti-aging effects by scavenging free radicals, inhibiting collagenase and elastase, increasing procollagen production, and reducing MMP-1 secretion, suggesting its potential use in functional cosmetics.

This study suggests that finasteride may upregulate BTG2 and CD244 gene expression through differential methylation, indicating potential as a treatment avenue for medulloblastoma.

This study suggests that a mild intramuscular dose of botulinum toxin improved spermatogenesis and sperm parameters in ageing mice.

This study found that BNC2 is critical for hair follicle regeneration and other developmental processes, as Bnc2−/− mice exhibit incomplete hair follicle development and developmental defects, and BNC1 cannot substitute for BNC2.

This article reviews the potential of Acyzol, a zinc-containing drug, to treat and prevent zinc deficiency conditions, but it reports no new clinical findings.

In this study, baicalin from Scutellaria baicalensis decreased androgen levels in both cells and PCOS model rats by inhibiting key gene expression, suggesting it may be a potential treatment for hyperandrogenism in PCOS.

5α-Reductase helps regulate hormone action in toad testes, especially during breeding season.

This study found that topical ruxolitinib protected Lgr5+ skin stem cells and maintained skin homeostasis in skin GVHD, unlike corticosteroids.

This review concludes that anabolic–androgenic steroid abuse may lead to significant neurotoxicity, affecting brain structure, neurotransmitter systems, and increasing the risk of mood disorders and cognitive deficits.
