Question

why does secretion of progesterone discontinued after a few days in non pregnant woman?​

Answer 1

Answer:

If the egg is not fertilised and no embryo is conceived, the corpus luteum breaks down and the production of progesterone decreases. As the lining of the womb is no longer maintained by progesterone from the corpus luteum, it breaks away and menstrual bleeding occurs, marking the start of a new menstrual cycle.
