• A. Luteal phase and lasts for 6 days
• B. Luteal phase and lasts for 13 days
• C. Follicular phase and lasts for 13 days
• D. Follicular phase and lasts for 6 days

Answer 1

The correct option is B Luteal phase and lasts for 13 days

The release of ovum is called the ovulatory phase. After ovulation, luteal phase follows. The luteal phase is the final phase of the ovarian cycle and it corresponds to the secretory phase of the uterine cycle. During the luteal phase, the remaining parts of the Graafian follicle transform as the corpus luteum. The corpus luteum secretes large amounts of progesterone which is essential for maintenance of the endometrium.
