The authors recommend a free androgen index test (FAI = total testosterone (nmolL−1) × 100/sex hormone-binding globulin (SHBG)) and prolactin as screening parameters for ovarian hyperandrogenism and dehydroepiandrosterone sulfate (DHEAs) and 17-hydroxyprogesterone (17-OH) as screening parameters for surrenal hyperandrogenism [23, 39, 62]. This evidence concerns the gene SHBG and Ovarian Hyperandrogenism.
