,
January 2000 in “The Journal of clinical endocrinology and metabolism/Journal of clinical endocrinology & metabolism” This study found that serum PSA levels are higher in hirsute women and can be significantly reduced by antiandrogen treatment, suggesting PSA as a marker of androgen action in females.
9 citations
,
October 2018 in “Medical Science Monitor” In this study, oral finasteride therapy was associated with decreased DHT levels and improved hair loss severity in young male AGA patients, while hormonal changes influenced the curative effect.

,
August 1999 in “The American journal of medicine” This study found that while a transscrotal testosterone patch increases serum testosterone levels in hypogonadal men with AIDS and weight loss, it does not improve weight, body cell mass, or quality of life.
January 2024 in “Journal of the Endocrine Society” In this study, correlations between urinary and serum androgen metabolites were examined in girls aged 6-13, revealing that summed urinary metabolites strongly correspond with circulating androstenedione and testosterone levels, though individual variations depend on participant characteristics such as age and body measurements.

15 citations
,
October 2011 in “Gynecological Endocrinology” 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.
September 2023 in “Clinical, Cosmetic and Investigational Dermatology” This study found a significant negative correlation between serum SHBG levels and androgenetic alopecia severity in women, but not in men, while no significant correlation was observed for testosterone, estradiol, dehydroepiandrosterone sulfate, and vitamin D levels with hair loss severity across genders.

,
April 2014 in “Hormones” This study found that increased serum A4A levels were associated with more severe polycystic ovary syndrome phenotypes and could be a useful marker for biochemical hyperandrogenemia.
