Correct answer: (d) Progesterone level is high during the post ovulatory phase of menstrual cycle.
Explanation:
- Rapid secretion of LH leading to its maximum level during the mid-cycle called LH surge.
- Oogenesis is initiated during the embryonic development stage when a couple of million gamete mother cells (oogonia) are formed within each fetal ovary (about third month of foetal ovary), no more oogonia are formed and added after birth.
- In the head of epididymis sperms undergo physiological maturation, acquiring increased motility and fertilizing capacity.
