A 28-year-old woman with history of repeated D&C presents with hypomenorrhea and secondary infertility. Which condition is most likely?

Correct option is B

Asherman’s syndrome (intrauterine adhesions) occurs after uterine instrumentation. It causes hypomenorrhea due to decreased endometrial surface and leads to infertility.
Explanation of options: (a) ✘ PCOS usually causes oligomenorrhea or amenorrhea with thick endometrium, not hypomenorrhea. (b) ✔ Correct; intrauterine adhesions after D&C cause scanty periods and infertility. (c) ✘ Premature ovarian failure → amenorrhea + high FSH, not hypomenorrhea. (d) ✘ Hypothalamic amenorrhea → no menstruation, not just scanty bleeding.
