Quizplus · Accepted Answer

The hCG receptor is critical for the maintenance of the corpus luteum in early pregnancy. By antagonizing the receptor, the corpus luteum will degenerate, causing a decline in progesterone and estrogen levels. This will ultimately result in the termination of the pregnancy. The secretion of large quantities of FSH and LH (A) or GnRH (B) would not be expected in this scenario. Secretion of large quantities of progesterone and estrogen (D) would also not occur due to the antagonistic effect of the drug on the hCG receptor. Cortisol (E) is not relevant to this scenario.
