B Patients with POF typically present with hot flashes, fatigue, and facial flushing. Lab work-up also reveals a marked decrease in ovarian hormones, estrogen and progesterone, and a significant increase in pituitary hormones, LH and FSH, which are no longer regulated by feedback inhibition. C This is not the correct set of lab results because in patients with POF, ovarian hormones are decreased, while pituitary hormones are increased due to an absence of feedback inhibition. D This is not the correct set of lab results because in patients with POF, ovarian hormones are decreased, while pituitary hormones are increased due to an absence of feedback inhibition. E This is not the correct set of lab results because in patients with POF, ovarian hormones are decreased, while pituitary hormones are increased due to an absence of feedback inhibition. The patient in this scenario presents with premature ovarian failure (POF), a primary ovarian defect characterized by depletion of ovarian follicle reserve before 40 years of age. Patients with POF might have primary amenorrhea, where menarche has been absent since birth, or secondary amenorrhea, where patients stop having menses before they reach the age of 40. The clinical signs and symptoms of POF are similar to those of menopause. Patients with POF typically present with hot flashes, fatigue, and facial flushing. Lab work-up also reveals a marked decrease in ovarian hormones, estrogen and progesterone, and a significant increase in pituitary hormones, LH and FSH, which are no longer regulated by feedback inhibition.<br/> '''Educational Objective:''' Premature ovarian failure (POF) is a state of primary ovarian defect, which mimics menopause, before the age of 40. In POF, ovarian hormones are decreased, while pituitary hormones are increased due to an absence of feedback inhibition.<br/> '''References:''' Beck-Peccoz P, Persani L. Premature ovarian failure.
