In Kirkuk City, a study of 1000 young lean female students with no underlying ovarian dysfunction or menstrual irregularity, i.e., non-PCOS etiology of hirsutism, has shown a significant correlation between hirsutism severity and serum FT, DHEAS, androstenedione, and sex hormone-binding globulin (SHBG). Here, SULT2A1 is linked to ovarian dysfunction.
