TLDR Women with excessive body hair often have higher male hormones and related health issues.
The study evaluated women who reported excessive body hair growth and found that those with hirsutism had significantly higher levels of testosterone and dehydroepiandrosterone sulfate, a higher free androgen index, and lower levels of sex hormone binding globulin (p<0.01). These women also more frequently experienced infertility, increased skin greasiness, and had higher body mass index, blood pressure, and waist/hip measurements compared to those without hirsutism.
September 2021 in “Journal of pharmaceutical research international” The conclusion is that hirsutism is strongly linked to PCOS and higher levels of certain hormones, but not to DHEAS, prolactin, cortisol, or TSH.
