This case study reports that hormonal imbalances in a young boy with precocious pseudopuberty returned to normal after the removal of a testicular interstitial cell tumor, with normal spontaneous puberty following.

This study found that young women with female-pattern hair loss exhibit increased testosterone production rates while dihydrotestosterone production rates remain within or below the normal range.

This study reports that new compounds with anti-androgenic effects were found to counteract testosterone in animals without significant estrogenic activity, indicating potential for managing androgen-related conditions.

This review suggests that oocyte retrieval may be viable for transgender men on testosterone therapy, with potentially manageable effects on fertility preservation without requiring extensive hormone suspension.

This study found that Lespedeza cuneata aqueous extract reduced serum dihydrotestosterone levels and 5α-reductase mRNA expression in testosterone-induced prostatic hyperplasia in rats, suggesting potential as a treatment for prostatic hyperplasia.

This case report describes a functional adrenocortical oncocytoma that co-secreted testosterone and cortisol.

This study found that finasteride effectively prevented testosterone-induced kidney stone formation in renal tubular cells by reducing COM crystal adhesion and crystallization.

This study found that obesity in PCOS women with biochemical hyperandrogenemia lowers androstenedione levels and increases the testosterone to androstenedione ratio, but this was not observed in women with clinical hyperandrogenemia or in controls.

This study found that testosterone propionate increased hair mass in female hamsters' flank organs, while cyproterone acetate applied topically reduced androgen-stimulated hair in a dose-dependent manner.

This study found that MENT is 10 times more potent than testosterone in suppressing gonadotropins and contributing to anabolism in monkeys, with a potentially wider therapeutic index for human androgen replacement and male contraception.

In this study, researchers observed that in barn owls, the relationship between black feather spot size and testosterone levels varied by age and sex, suggesting involvement of genes regulating both traits rather than direct influence of testosterone on feather coloration.

In this study, topical EGCG significantly reduced testosterone-induced hair loss and follicular apoptosis in mice, without altering testosterone or dihydrotestosterone concentrations.

This article discusses whether testosterone's metabolism to 5α-dihydrotestosterone is necessary for androgenic effects in the skin but reports no new experimental results.

This study observed that direct exposure to androgens in Western clawed frogs differentially affects thyroid receptor and deiodinase gene expression in male and female tissues, offering insight into sex-specific metabolic pathway activation.

In this study, A. capillus-veneris solution demonstrated potential to reduce hair loss and improve hair characteristics in a testosterone-induced alopecia mouse model.

This review discusses the limitations of serum androgen measurements in diagnosing and treating women with potential androgen-related disorders and the potential role of androgen replacement therapy for those with sexual interest/arousal disorders, reporting no new results.

This study found that progesterone levels were higher and increased significantly throughout pregnancy, contrasting with stable levels in non-pregnant women.

Testosterone may both worsen and protect against COVID-19 effects in men.

This study found that prostate cancer aggressiveness in men with obesity is associated with changes in age, BMI, testosterone, and estradiol levels, and that adipocyte-secreted molecules increase cancer cell aggressiveness in vitro.

This study found that a new hydrogel formulation of basic fibroblast growth factor showed promise in promoting hair regrowth and reducing inflammation in testosterone-treated mice.

This study reported that pulverizing hair samples significantly improves the precision of testosterone measurement, with higher testosterone concentrations observed in men than in women.

This study in male mice found that testosterone provides strong protection against skin necrosis after ischemia, working through its estrogenic and androgenic derivatives to enhance skin survival and revascularization, with 17β-estradiol being notably more effective than dihydrotestosterone.

This report describes a 19-year-old male with 49,XXXXY syndrome receiving testosterone replacement therapy, which led to improvements in reproductive development, metabolism, and social interaction after a year of treatment.

Young and adult hamsters both respond similarly to testosterone and finasteride treatments, but young hamsters aren't good for testing the inhibitory activity of a specific enzyme.

This study found that a daily dose of 50 mg DHEA only slightly increased the urinary testosterone/epitestosterone ratio for a short period, without exceeding the IOC's acceptable limit.

This report introduces a mouse model with androgen-dependent alopecia, suggesting it as a potential alternative for studying hair loss mechanisms and testing treatments.

This study found that combining oral testosterone with dutasteride increased testosterone bioavailability in hypogonadal men while suppressing dihydrotestosterone levels over a 28-day period.

This study found that testosterone enhances insulin secretion in human pancreatic islets by being converted into DHT and E2, processes that are necessary for this effect.

This study found that testosterone replacement therapy, especially intramuscular administration, significantly increased PSA levels compared to placebo, while a significant correlation between PSA and testosterone was observed in non-BPH patients.

This review highlights the potential therapeutic applications of nandrolone, an anabolic steroid, for male health, but notes that more human studies are needed due to limited existing literature.
