Explanation:
Detailed explanation-1: -The pregnancy hormone human chorionic gonadotropin (hCG) supports and maintains the corpus luteum. The corpus luteum begins to decrease in size at around 10 weeks of pregnancy. When fertilization or implantation does not occur, the corpus luteum will begin to break down.
Detailed explanation-2: -Its role is to prevent the disintegration of the corpus luteum of the ovary and thereby maintain progesterone production that is critical for a pregnancy in humans. hCG may have additional functions; for instance, it is thought that hCG affects the immune tolerance of the pregnancy.
