Previous studies have described the presence of a hormonal PCOS-like pattern in men with early-onset AGA, including low levels of SHBG [20–22, 24, 29, 47] and FSH [20–22, 29], and increased levels of 17αOH-P [21] and DHEAS [23, 24]. The gene discussed is BRD2; the disease is polycystic ovary syndrome.
