,
December 2008 in “Clinical Endocrinology” This study found that young males with stage III or higher androgenetic alopecia had higher insulin resistance and cardiovascular-related features, suggesting the need for metabolic assessment in this population.
44 citations
,
January 2008 in “Fertility and Sterility” This study suggests that androgen receptor gene CAG repeat length may influence serum free testosterone levels in some PCOS patients, with longer repeats associated with higher testosterone concentrations.
39 citations
,
September 2012 in “Human Reproduction” This study found that specific SHBG gene variants, rs727428 and rs6259, were associated with PCOS in Mediterranean women, although the associations were relatively weak and do not indicate a causative role.
