As indicated in Table 3, there were no statistically significant differences in the eight major confounders associated with serum AMH levels (age, BMI, pregnancy history, serum CEA levels, menstrual regularity, dysmenorrhea history, hypertension, and diabetes) between PCOS and non-PCOS subjects, regardless of whether the endometrium was normal or exhibited AEH lesions. This evidence concerns the gene AMH and polycystic ovary syndrome.
