Ovulation takes place due to the rapid secretion of LH in female primatesJust before the end of the secretory phaseAt the beginning of the proliferative phaseAt the end of the proliferative phaseAt the mid-secretory phase
Solution
Ovulation in female primates occurs due to the rapid secretion of Luteinizing Hormone (LH). This typically happens around the middle of the menstrual cycle, not at the end of the secretory phase, the beginning of the proliferative phase, or the mid-secretory phase.
Here are the steps of the menstrual cycle:
-
Menstrual Phase (Day 1 to 5): The cycle starts with menstrual bleeding which is the shedding of the uterine lining.
-
Follicular Phase (Day 1 to 13): This phase overlaps with the menstrual phase. The pituitary gland secretes Follicle Stimulating Hormone (FSH) which stimulates the ovary to produce about 5 to 20 follicles (tiny nodules or cysts). Each follicle houses an immature egg.
-
Ovulation Phase (Day 14): The level of LH surges (LH surge), leading to the release of the egg from the most mature follicle - this process is called ovulation.
-
Luteal Phase (Day 15 to 28): Post ovulation, the ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces progesterone.
So, ovulation takes place due to the rapid secretion of LH, typically around the middle of the menstrual cycle.
