Which of the following is secreted principally by the corpus luteum of the human ovary?
Correct answer: B. Progesterone
- A. Luteinizing hormone
- B. Progesterone
- C. Follicle-stimulating hormone
- D. Testosterone
Explanation
The corpus luteum secretes estrogens and progesterone. The latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. If the egg is not fertilized, the corpus luteum becomes inactive after 10-14 days, and menstruation occurs.
