Question

The main function of corpus luteum is to

• A. secrete progesterone
• B. facilitate ovulation
• C. facilitate fertilization
• D. facilitate passage of ova in oviduct

Answer 1

The correct option is A secrete progesterone

The ovulation (ovulatory phase) is followed by the luteal phase during which the remaining parts of the Graafian follicle transform as the corpus luteum. Ovulation is facilitated by LH surge.
The corpus luteum secretes large amounts of progesterone which is essential for maintenance of the endometrium. Such an endometrium is necessary for implantation of the fertilized ovum and other events of pregnancy.
