The corpus luteum produces hCG, which activates adenylyl cyclase in target cells to produce cAMP. If adenylyl cyclase is blocked, the corpus luteum would not respond to hCG, leading to a decrease in progesterone production and potentially leading to early pregnancy loss. The other answer choices do not involve hCG or adenylyl cyclase.
