A) FSH
B) hCG
C) Progesterone
D) Androgen

The primary secretion of the corpus luteum is progesterone, which prepares the uterus for pregnancy by stimulating the growth of blood vessels and glands in the endometrium. It also plays a role in maintaining pregnancy by inhibiting contractions of the uterus and suppressing immune responses that could reject the fetus.
