Over the past year, menses occurred at irregular 30- to 45-day intervals with light flow. The patient underwent two successful cesarean sections at the ages of 28 and 32. She has two healthy children. She is sexually active with her husband and does not use condoms. Her vital signs are within normal limits. Physical examination shows no abnormalities. Laboratory studies show:Estradiol 8 pgmL mid-follicular phase: N27123 pgmLFollicle-stimulating hormone 200 mIUmLLuteinizing hormone 180 mIUmLProlactin 16 ngmLWhich of the following is the most likely diagnosis?? A: Primary hypothyroidism, B: Pregnancy, C: Premature ovarian failure, D: Polycystic ovary syndrome, E: Major depressive disorder,  <response>: This is a question about a 36-year-old woman with amenorrhea, headaches, difficulty sleeping, increased sweating, and irregular periods over the past year. The key findings are amenorrhea for 4 months, elevated FSH and LH levels, and low estradiol level. The elevated FSH and LH along with low estradiol indicate ovarian failure. The amenorrhea and perimenopausal symptoms such as headaches and sweating are consistent with premature ovarian failure. The irregular periods over the past year also point towards premature ovarian decline. The other options can be ruled out:- Primary hypothyroidism - no indication of thyroid dysfunction. TSH would be elevated.- Pregnancy - estradiol level too low and no mention of positive pregnancy test. - Polycystic ovary syndrome - would see high, not low estradiol. No mention of other PCOS features like hirsutism or obesity.- Major depressive disorder - does not explain the hormonal abnormalities or amenorrhea.C: Premature ovarian failure
