Serum androgens and prostate‐specific antigen levels in androgenetic alopecia: is there a difference between frontal and vertex baldness?

Abstract

Vertex baldness may signal higher exposures to circulating DHT. Serum PSA level cannot serve as surrogate diagnostic marker of increased androgenic activity in men with AGA.

Association between Androgenetic Alopecia and Psychosocial Disease Burden: A Cross‐Sectional Survey among Polish Men

“…In this study, however, patients were examined only by one dermatologist which eliminates differences that might appear due to disagreements between researchers. Furthermore, the Norwood-Hamilton Baldness Scale has been widely used in clinical trials among Polish patients with AGA in order to classify the pattern of hair loss and to evaluate its severity [20]. Next, all men were asked to answer a 2-part questionnaire which comprised of 23 questions in total.…”

Testosterone Analysis in Hair

“…A localised hair loss in male-pattern baldness is in part caused by more androgen receptors available in the balding scalp, as well as increased levels of dihydrotestosterone due to local activity of the enzyme 5a-reductase [87,89,90]. There have also been some reports on higher circulating testosterone and dihydrotestosterone concentrations in men with certain types of male-pattern baldness [91][92][93]. Thus, there is a possibility for selection bias when males with male-pattern baldness are excluded from hair hormone analyses.…”
