In this case-control study of Dravidian men from Tamil Nadu, we observed no significant association between androgenic alopecia or hypertrichosis and prostate cancer. These findings contrast with data from Western cohorts, suggesting that interethnic variation in androgen receptor polymorphisms, follicular sensitivity, and environmental exposures may modulate prostate cancer risk differently. Further research is needed to elucidate how androgenic traits influence prostate carcinogenesis across different ethnic groups.
Narayanan et al. (Sun,) studied this question.
