This review examines existing research on androgen deprivation therapy and its effects on male sex hormones in relation to COVID-19, but reports no new clinical findings.

This case study reported a postmenopausal woman with a testosterone-secreting ovarian tumor that was not detected through standard clinical or radiological examination but was found via biopsy.

In this study, the authors concluded that androgens, but not estrogens, strictly mediate the maintenance of neuromuscular morphology in the spinal nucleus of the bulbocavernosus in adult rats.

In this study, significant elevations of DHA and testosterone were associated with pubic hair development and voice changes in boys during puberty.

Estrogen may help improve COVID-19 outcomes, especially in women.

In this study, testosterone and finasteride were found to increase insulin and zinc levels while decreasing chromium levels in male adult rats, suggesting potential effects on the glucose cycle.

This study found that testosterone increased seizure severity in mice and rats, with its neurosteroid metabolites playing a role in modulating seizure susceptibility.

This review describes how male hypogonadism can lead to various skin and hair symptoms, as well as potential dermatological reactions to hormone treatments and reports no new clinical results.

This study found that hypogonadism in men can be a reversible risk factor for torsades de pointes (TdP), with testosterone replacement potentially preventing TdP recurrence.

This study identified hypogonadism in 65% of men with Cushing syndrome, suggesting glucocorticoid excess may affect the hypothalamic-pituitary level or testosterone metabolism.

This narrative review highlights that declining testosterone levels are a complex public health issue potentially influenced by modifiable lifestyle factors and environmental stressors, suggesting integrated strategies may be needed to address the trend's impacts on health.

This study found that total testosterone, DHEA-S, and free androgen index may help distinguish menstrual irregularities from increased risk of polycystic ovary syndrome in adolescents.

This study found that Turner’s syndrome is associated with significant bone mass decrease due to estrogen deficiency, which can be improved with estrogen therapy, while bone issues in Klinefelter’s syndrome may benefit from early androgen therapy and possibly bisphosphonates.

This study found that testosterone replacement, with or without finasteride, did not lead to significant cognitive improvements over 36 months in healthy older men without prior cognitive impairment.

This study found that steroid hormones influence the quality indicators of fresh and cryopreserved stallion sperm, with testosterone negatively correlated with motility and estradiol positively correlated with survival rate.

This study found that approximately 75% of women with PCOS exhibited hyperandrogenemia, with free testosterone being the most frequently elevated marker.

This study found that disrupting testosterone biosynthesis in male rats mitigated cardiovascular and autonomic impairments caused by endotoxemia, indicating testosterone's significant role in these conditions.

This study concluded that albumin-bound testosterone is biologically important and significantly contributes to testosterone bioavailability in women receiving spironolactone.

In this study, the authors concluded that clinical hyperandrogenism is not a reliable predictor for biochemical hyperandrogenism in Thai women with PCOS.

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 that the risk of urinary stone disease increased significantly in patients with severe androgenetic alopecia, and that testosterone deficiency was more frequent among these patients.

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.

In this narrative review, the authors discuss the potential impact of hormone therapy on androgenetic alopecia among transgender individuals, especially transgender men using testosterone, and its adverse effects on emotional well-being and body image within a socially stigmatized population.

This review discusses the use of anabolic-androgenic steroids in sports and outlines current methods for detecting urinary steroid doping, particularly testosterone, but reports no new experimental findings.

This case study describes a rare steroid cell tumor of the ovary in a 42-year-old woman, highlighting its virilizing effects and the importance of thorough follow-up due to its potential for malignancy.

In this study, testosterone and certain metabolites were highly effective in promoting sebaceous structure growth in the female hamster flank organ, while others had limited or no effect.

This case study reports that a virilizing Leydig cell type ovarian tumor in a 40-year-old woman caused hyperandrogenism and virilization symptoms, which improved post-surgery.

This review discusses the effects of cross-sex hormone treatments on metabolic functions in transgender individuals and reports no new clinical results; it highlights potential insights into the role of sex steroids in diseases like cardiovascular disease and diabetes.

This article suggests that testosterone therapy might be considered if other treatments fail, but emphasizes discussing potential risks and benefits with patients before prescribing.

This article discusses the various administration methods and considerations for testosterone replacement therapy, highlighting the importance of individualized therapeutic monitoring and potential adverse effects, but reports no new clinical results.
