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.
The corpus luteum secretes progesterone & other hormones to maintain early pregnancy which maintains the uterine lining during the first months of pregnancy. The corpus luteâ¦um in the ovary results from the release of an egg. It now produces progesterone to maintain the endometrium of the uterine walls. The corpus luteum is a yellow body. Before it released the egg, it was white and referred to as the corpus albicans (white body).
