corpus luteum

Definition: Corpus luteum is 1 to 2 cm, round yellow, lobulated structure with cystic center. It has luteinized granulosa and theca cells.

In pregnancy, coprus luteum is larger, bright yellow with prominent central cavity, hyaline droplets and calcification. Progesterone from the corpus luteum maintains the uterus for implantation.

The corpus luteum secretes progesterone which induces a secretory endometrium. It normally regresses in 14 days unless it is rescued by increasing concentrations of human chorionic gonadotropin from a pregnancy.
