Primary ovarian insufficiency (POI) is defined as the presence of amenorrhea for ≥ 4 months accompanied by evidence of two serum follicle-stimulating hormone levels in the menopausal range in women aged &lt; 40 years. Anti-Müllerian hormone (AMH) has been recognized as the most reliable marker of ovarian reserve status, and its serum level is very low or undetectable in women with POI. Here we report two cases of patients who were diagnosed with POI despite high serum AMH levels and preservation of ovarian follicles, as revealed by ultrasound. In addition, we have presented a review of the current literature regarding this condition.
