Correct Answer: Human chorionic gonadotropin (hCG)
Description: The corpus luteum secretes estrogens, progesterone, and relaxin. hCG, secreted by the syncytiotrophoblast lining the placental villi, maintains the corpus luteum during the first trimester of pregnancy. Antidiuretic hormone (vasopressin does not play a significant role during pregnancy. FSH acts on granulosa cells to promote the conversion of androstenedione to estradiol. LH acts on theca cells to promote androstenedione secretion. Ref: Barrett K.E., Barman S.M., Boitano S., Brooks H.L. (2012). Chapter 22.
