Progesterone causes the endometrial glands to secrete, preparing the endometrium for blastocyst implantation. If the oocyte is fertilized, the corpus luteum enlarges to form a corpus luteum of pregnancy and increases hormone production. With pregnancy, chorionic gonadotropin, secreted by the trophoblast of the chorion, prevents degeneration of the corpus luteum.
Once the corpus luteum regresses the remnant is known as corpus albicans. Function. The corpus luteum is essential for establishing and maintaining pregnancy in females.
