Solution
The correct option is C FSH, LH and estrogen
The reproductive cycle in the female primates (e.g., monkeys, apes, and human beings) is called menstrual cycle. The first menstruation begins at puberty and is called menarche. In human females, menstruation is repeated at an average interval of about 28 / 29 days, and the cycle of events starting from one menstruation till the next one is called the menstrual cycle. The 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. These changes in the ovary and the uterus are induced by changes in the levels of pituitary and ovarian hormones. 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. The ovulation (ovulatory phase) is followed by the luteal phase during which the remaining parts of the Graafian follicle transform as the corpus luteum.
