This study found that 9 out of 12 women with acne or alopecia showed subjective improvement with finasteride treatment despite having normal free testosterone levels, suggesting a potential role of 5alpha-reductase activity.

This study found that intravaginal testosterone significantly improved sexual satisfaction and reduced dyspareunia in postmenopausal women using aromatase inhibitors, with no effect on urinary incontinence.

This study found that calculated parameters like free testosterone and bioavailable testosterone were higher in women with hirsutism and PCOS compared to controls, suggesting these might better assess hyperandrogenemia than measured hormone values.

This study determined that a total testosterone concentration of ≥5.1 nmol/L identified androgen-producing tumors in women with severe hyperandrogenemia, while a lower threshold of ≥2.2 nmol/L was found for diagnosing pathologic hyperandrogenism in postmenopausal women.

Finasteride increases hair growth, prolongs hair cycle, and lowers dihydrotestosterone levels.

This study provides a guideline for the safe and effective use of testosterone in women with hypoactive sexual desire disorder, recommending systemic transdermal testosterone for appropriate candidates while highlighting the importance of informed consent and monitoring due to unestablished long-term safety.

This study found that men with early-onset androgenetic alopecia and certain risk factors may have worse gonadal steroidogenesis and an increased likelihood of developing gonadal dysfunction, suggesting a male equivalent of polycystic ovarian syndrome.

This study measured plasma testosterone glucosiduronate levels and found no overlap in those with hyperandrogenism compared to normal females, despite normal testosterone and dihydrotestosterone levels in half of the affected patients.

This study found that elevated free testosterone levels may reduce body fat and increase bone density in males, but also raise the risk of prostate cancer, hair loss, and benign prostate hyperplasia.

This study found that school-related stress increases hair cortisol in girls and alters hair testosterone and cortisol levels in boys, indicating gender-specific hormonal responses to environmental changes.

This study used enhanced Raman spectroscopy to successfully detect ultra-low levels of free testosterone in women with PCOS, suggesting a potential low-cost method for early diagnosis.

This study found that sheep testis extract significantly improved wound healing and hair follicle growth in rats, suggesting it may be a promising candidate for clinical wound healing research.

This study conducted at Tribhuvan University Teaching Hospital found no significant correlation between serum testosterone levels and acne severity in adult female patients with acne, suggesting that serum testosterone is not a reliable marker of androgen excess in this sub-population.

In this study using a rat model, researchers observed that applying topical testosterone led to changes in the skin resembling early acne lesions, indicating a dermatologic risk potentially associated with over-the-counter testosterone products.

This article discusses the causes and consequences of hyperestrogenism in men of reproductive age and emphasizes the need for proper hormonal testing and treatment, reporting no new clinical findings.

The authors propose that higher testosterone levels in hospitalized COVID-19 patients might be associated with worse outcomes.

This study found that women with hair loss had significantly higher free testosterone levels compared to those without hair loss.

In this study, adolescent male acne patients with normal serum testosterone showed improved outcomes with finasteride plus lifestyle intervention, significantly reducing DHT and free testosterone levels and improving SHBG levels, with minimal adverse effects.

This study found no significant differences in plasma DHEA-S and total testosterone levels between female patients with androgenetic alopecia and normal controls, regardless of clinical type or hyperandrogenic symptoms.

This study found that women with androgenetic alopecia had significantly higher mean plasma levels of DHEA-S and total testosterone compared to normal females, despite most individuals in both groups being within normal hormonal ranges.

In this study, elevated serum levels of aldosterone and free testosterone, along with increased androgen and aldosterone receptor levels, were associated with early-onset androgenetic alopecia in female patients.

In this study, women with male pattern alopecia had significantly lower serum sex hormone binding globulin levels compared to healthy controls, while testosterone levels remained similar.

In this study, researchers investigating the Drosophila testis niche system reported that Notch signaling is crucial for niche cell specification, with early gonadogenesis showing signals coming from outside the gonad to direct cell fate.

This study found that lower serum testosterone levels were significantly associated with an increased prevalence of kidney stones in men over 40, but not in those aged 20–40.

This study found that among men with serum testosterone levels below 3.33 ng/mL, the prevalence of kidney stones was significantly higher, independent of other metabolic factors.
