What is the primary function of the corpus luteum?
- A. Produce a mature ovum
- B. Produce progesterone and estrogen
- C. Stimulate initial growth of the endometrium

A: The ovum is produced in the ovary, not the corpus luteum.
C: The endometrial growth is primarily influenced by estrogen and progesterone, not the corpus luteum.
D: The maturation of the next follicle is regulated by hormones like follicle-stimulating hormone (FSH) and luteinizing hormone (LH), not the corpus luteum.
