During the follicular phase, the primary follicles in the ovary grow to become a fully mature Graafian follicle and simultaneously the endometrium of uterus regenerates through proliferation.
Ovulation is followed by the luteal phase where the Graafian follicle is transformed into corpus luteum.
Rapid secretion of LH leading to its maximum level during the mid-cycle called LH surge induces rupture of Graafian follicle, and thereby, the release of the ovum.
The corpus luteum secretes large amounts of progesterone, which is essential for the maintenance of the endometrium.
