Testosterone causes hair loss in AGA mice, which are good for testing baldness treatments, and both minoxidil and cyproterone acetate can prevent this hair loss.

This review presents substantial evidence supporting testosterone use for hypoactive sexual desire disorder in postmenopausal women, but notes safety concerns with off-label prescribing due to lack of approved formulations.

In this study, androgen receptors were found only in the mane follicles of red deer stags during the breeding season, suggesting their expression is induced by seasonal hormone changes.

This study found that androgen binding in male rat livers involves specific androgen receptors, which decrease with castration and are inducible in female livers with testosterone.

This guideline provides evidence-based recommendations for prescribing testosterone therapy to women with hypoactive sexual desire disorder, noting a moderate therapeutic benefit but highlighting limited data and regulatory challenges.

This study concluded that the best approach for detecting Androsta-1,4,6-triene-3,17-dione administration in horses is monitoring the metabolites M1b or M4 in urine, detectable up to 77 hours post-administration.

This study found that finasteride impaired object recognition memory and altered hippocampal dendritic structures in male 3xTg-AD mice, suggesting potential sex differences in Alzheimer's disease pathology.

This study found that male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

This study reported that newly synthesized progesterone derivatives significantly reduced prostate weight in testosterone-treated hamsters, with 5alpha-reductase inhibitory activity dependent on the size of the substituent at C-17.

Male hormones control a specific gene in hamster skin, with different hormones having varying effects.

This study reported that 5 alpha-reductase type 2 is the predominant enzyme in pubic skin fibroblasts across normal men, women, and hirsute patients, suggesting potential treatment options for idiopathic hirsutism.

This review discusses androgen deficiency syndrome in women, its symptoms, and how androgen replacement therapy generally alleviates related issues without significant side-effects, but reports no new clinical findings.

This study observed that testosterone therapy in transgender men enhances both physical and mental health, is safe in the short and middle term with proper follow-up, and highlights the need for endocrinologists to provide gender-affirming care despite its limited presence in medical education.

This review discusses the role of androgens in women's sexual health and highlights the need for further research on androgen replacement therapy to optimize quality of life, but reports no new clinical results.

This review discusses the changes in androgen levels with age in women and the potential benefits of testosterone replacement therapy as part of hormone replacement therapy for postmenopausal women, but it reports no new clinical results.

This study suggests that policosanol may prevent androgenetic alopecia in mice by regulating hormone levels and suppressing premature hair follicle entry into the regression phase.

This study found that LHE may prevent and reverse testosterone-induced prostatic hyperplasia, supporting the traditional use of Kigelia africana for some reproductive system disorders.

This review discusses the controversial cardiovascular safety and efficacy of subcutaneous testosterone therapy in postmenopausal women, noting that its long-term use appears safe, but CV risk assessments remain disputed.

The researchers reported that a 5% Beta vulgaris L. extract nanogel showed better antialopecic activity in testosterone-induced alopecia in mice compared to a 2.5% concentration.

In this study, fenugreek seed extract showed significant androgenic and spermatogenic effects in male rats, likely through inhibiting testosterone metabolism, without impacting cardiovascular health.

This study demonstrated that steroidal carbamates 7–10 altered mRNA expression related to lipid metabolism in hamster flank organs and inhibited 5α-reductase activity without binding to the progesterone receptor.

This study found that various steroids affected the mRNA expression of enzymes involved in lipid metabolism in hamster flank organs, with different impacts depending on the steroid and combination used.

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

This study found that olive leaves extract significantly decreased prostate index, serum PSA, testosterone, and DHT levels in male rats with testosterone-induced benign prostatic hyperplasia, and showed potential as a therapeutic option due to its positive effects on prostate histology and antioxidant activity.

Men with early balding should be checked for metabolic syndrome, as there's a link between the two.

This review discusses the 2011 publications on the side effects of sex hormones and related compounds, without reporting new clinical results.

This source suggests that migraine prevalence increases in transgender women using oestrogen and decreases in transgender men using testosterone, with high oral oestrogen doses in transgender women potentially linked to aura risk.

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 review discusses the roles of androgens and estrogens in skin functions and disorders, and highlights the use of estrogen-progestin treatments and anti-androgens in managing hirsutism and acne, without reporting new results.

This review discusses the role of 5α-reductase in prostate development and BPH, and reports no new clinical results; ongoing trials are exploring dual isozyme inhibitors for improved treatment efficacy.
