This review examines the long-term health risks of anabolic-androgenic steroid abuse in athletes, reporting various physical and psychological side effects without sufficient benefits.

This study found that in men, elevated androgen levels can occur at any age, with older men potentially exhibiting increased total testosterone due to higher levels of SHBG, and younger men showing various clinical manifestations like acne and alopecia.

This study found no correlation between clinical signs and sex steroid levels in ferrets with hyperadrenocorticism and noted that androstenedione was elevated in many cases.

This abstract is a website placeholder and reports no research findings or results; it contains navigation and policy information for JAMA Dermatology.

In this case report, a male patient with hair loss showed unusually high testosterone levels without other symptoms or supplement use; follow-up testing revealed normal levels, showcasing the importance of considering testosterone-protein binding differences and using equilibrium dialysis for accurate assessment.

This case study concluded that weight loss is the initial recommended approach for treating secondary hypogonadism, as shown by improvements in testosterone levels and symptoms in an obese 37-year-old patient.

This clinical letter identifies Rothmund-Thomson syndrome type 2 as a rare cause of chronic wounds, but provides no new experimental findings.

This article reviews the role of hormones in human penis development and associated conditions due to hormonal imbalances, but reports no new findings, suggesting hormone replacement can manage some conditions.

In this study, homozygous VDR null mutant mice exhibited nonfunctional vitamin D receptors, leading to growth abnormalities and revealing the limited physiological importance of vitamin D pathways outside the classical receptor.

This study found no SARS-CoV-2 RNA in the semen and urine of a COVID-19 patient, suggesting possible viral clearance or absence in these fluids.

This review discusses nonclassical 21-hydroxylase deficiency as the most common autosomal recessive disorder in humans and highlights the effectiveness of glucocorticoid treatment in reversing related symptoms.

Finasteride treats enlarged prostate, shrinks it, improves urination, but may cause sexual dysfunction and isn't for women or children.

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 the properties and therapeutic potentials of beta-sitosterol, highlighting a need for more detailed studies on its mechanisms and long-term effects in humans; it reports no new results.

This study found that discontinuing finasteride led to a significant increase in sperm counts for most men with reduced fertility, though hormone levels and other semen parameters remained unchanged.

This review assesses the current literature on COVID-19's effects on male sexual and reproductive health, highlighting significant research gaps and providing guidance for patient counseling.

This study found that SRD5a-3 is a highly efficient enzyme for converting hormones into androgens, with dutasteride being a much more potent inhibitor of SRD5a-3 than SRD5a-2.

This study found that men experiencing long-term symptoms after finasteride use for androgenetic alopecia frequently reported loss of penis sensitivity and anhedonia, among other effects, indicating potential post-finasteride syndrome.
