Why does the corpus luteum deteriorate?

What does regressing corpus luteum indicate?

A regressing corpus luteum indicates that the egg was not fertilized. As the corpus luteum regresses it loses its capacity to produce progesterone.

Why is the corpus luteum important to reproduction?

The corpus luteum produces progesterone during the time that the placenta is forming, about the first trimester. After the placenta is mature, it will continue to produce progesterone while the corpus luteum degenerates. Progesterone is an important pregnancy hormone. Pregnancy cannot continue without it.
