D
Human Chorionic Gonadotropin (hCG)
Verified step by step guidance
1
Understand the role of the corpus luteum: The corpus luteum is a temporary endocrine structure in female ovaries that plays a crucial role in maintaining pregnancy by producing progesterone.
Identify the function of each hormone listed: Luteinizing Hormone (LH) triggers ovulation and the formation of the corpus luteum, Follicle-Stimulating Hormone (FSH) is involved in the maturation of ovarian follicles, and Progesterone is produced by the corpus luteum to maintain the uterine lining.
Recognize the role of Human Chorionic Gonadotropin (hCG): hCG is a hormone produced by the placenta shortly after implantation. It is crucial for maintaining the corpus luteum during the early stages of pregnancy.
Connect hCG to the prevention of corpus luteum degeneration: hCG mimics the action of LH, which supports the corpus luteum, preventing its degeneration and ensuring continued production of progesterone.
Conclude that hCG is the hormone responsible for preventing the degeneration of the corpus luteum, thereby supporting early pregnancy.
