13053.	Question : Mature Graafian follicle is generally present in the ovary of a healthy human female around :
Answer» 5 - 8 day of menstrual cycle 11 - 17 day of menstrual cycle 18 - 23 day of menstrual cycle 24 - 28 day of menstrual cycle Solution :In humanfemales MENSTRUATION cycle lasts till 28 to 29 days. In proliferative phase, under the effect of follicle stimulating hormone (FSH), primary follicles grow and convert into mature graafian follicle. This proliferative phase lasts for 14 days. The secretion of gonadotrophins (LH and FSH) increase gradually during the follicular phase and stimulate follicular development as well as secretion of estrogens by the growing follicles. Both LH and FSH ATTAIN peak level in the middle of cycle (about 14th day). Rapid secretion of LH leading to its maximum level during the mid cycle called LH surge induces rupture of graafian follicle and there by the RELEASE of ovum (ovulation). The ovulation is FOLLOWED by the luteal phase during which the remaining parts of the graafians follicle transfers as the corpus luteum.
