For hormonal parameters, serum AMH levels were significantly associated with PCOS phenotypes, with the highest median AMH levels observed in Phenotype A and the lowest in Phenotype B. However, no significant associations were identified between the PCOS phenotypes and serum LH, FSH, LH:FSH ratio, TSH, prolactin, or total testosterone levels. The gene discussed is AMH; the disease is polycystic ovary syndrome.
