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 primary function of the corpus luteum is to. A support pregnancy in the second and third trimesters. B nourish and protect the egg cell. C stimulate the development of the mammary glands. D maintain progesterone and estrogen synthesis after ovulation has occurred. E produce prolactin in the alveoli.
