Describe the four phases of the menstrual cycle.
Original Khojo Papers practice question — not from a past board paper.
Answer
In the menstrual phase, days 1 to 5, the thickened uterine lining is shed with some blood. In the follicular or proliferative phase, days 6 to 13, a follicle ripens and the lining is rebuilt under the influence of oestrogen. Ovulation occurs about day 14, when the ovum is released. In the luteal or secretory phase, days 15 to 28, the corpus luteum secretes progesterone and keeps the lining ready for implantation.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
If fertilisation does not take place, the corpus luteum degenerates and the cycle begins again.
