Original Khojo Papers practice question — not from a past board paper.
Answer
Follicle-stimulating hormone causes the follicle to grow and secrete oestrogen. Oestrogen rebuilds the uterine lining and triggers the surge of luteinising hormone. Luteinising hormone causes ovulation and the formation of the corpus luteum. Progesterone from the corpus luteum maintains the lining ready for implantation.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The fall in progesterone when the corpus luteum degenerates brings on menstruation.
