Answer 2

The inhibition of progesterone is necessary for the disintegration of corpus luteum.

• Progesterone is made in the ovary through the corpus luteum.
• Its function is to prepare for the reception and development of the fertilized ovum by the endometrium. It also suppresses oestrogen production after ovulation.
• Corpus luteum continues to produce progesterone during pregnancy. However, if pregnancy does not occur, corpus luteum begins to disintegrate.
• The levels of oestrogen and progesterone suddenly fall on about 28 day, resulting in the menstrual cycle beginning.
