Quizplus · Accepted Answer

Human chorionic gonadotropin (hCG) is not involved in the initiation of labor. It is primarily responsible for maintaining the corpus luteum during early pregnancy and is produced by syncytiotrophoblasts in the placenta. However, the other hormones listed, such as corticotropin-releasing hormone (CRH) from the placenta, DHEAS from the fetal adrenal gland, and cortisol from the mother and fetus, all play important roles in the initiation of labor.
