Explanation:

It occurs at about day 14 of a 28-day menstrual cycle. Specifically, ovulation is the release of the egg (ovum) from a woman's ovary. Each month, between days six and 14 of the menstrual cycle, follicle-stimulating hormone causes follicles in one of a woman's ovaries to begin to mature.

In human females, the menstrual cycle starts with the menstrual phase when menstrual flow occurs and it lasts for 3-5 days. The menstrual phase is followed by the follicular phase. During this phase, the primary follicles in the ovary grow to become a fully mature Graafian follicle and simultaneously the endometrium of uterus regenerates through proliferation. The secretion of gonadotropins (LH and FSH) increases gradually during the follicular phase and stimulates follicular development as well as secretion of estrogens by the growing follicles. Both LH and FSH attain a peak level in the middle of the cycle (about 14th day). Rapid secretion of LH leading to its maximum level during the mid-cycle, called as LH surge induces rupture of Graafian follicle and thereby the release of the ovum (ovulation). The ovulation (ovulatory phase) is followed by the luteal phase during which the remaining parts of the Graafian follicle transform as the corpus luteum.
