Corpus Luteum - PERLA Health

Corpus Luteum

The corpus luteum (CL) is formed from the remaining follicle once the egg cell has been released during ovulation. It becomes a dynamic gland that produces hormones such as progesterone, which has an impact on the uterine lining and prepares the uterus for the implantation of a fertilized egg cell. If there is no implantation of a fertilized egg, the corpus luteum shrinks again, and progesterone levels fall until the next cycle.
