|Prompt=A 38-year-old female presents to the physician's office with complaints of fatigue, hot flashes, and facial flushing. Upon further questioning, she informs the physician that she has not had her menses for 14 months. Following appropriate work-up, the diagnosis of premature ovarian failure (POF) is made. Which of the following set of lab results are most likely seen in this patient?

|Explanation=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.

Explanation [[Explanation::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.
