Progesterone helps to suppress maternal immunological responses to fetal antigens,thereby preventing maternal rejection of the fetus.Estrogen enhances myometrial activity,promotes myometrial vasodilation,increases maternal respiratory center sensitivity to carbon dioxide,softens fibers in the cervical collagen tissue,increases the pituitary secretion of prolactin,increases serum-binding proteins and fibrinogen,decreases plasma proteins,and increases sensitivity of the uterus to progesterone in late pregnancy.Human placental lactogen regulates glucose availability for the fetus and promotes fetal growth by altering maternal protein,carbohydrate,and fat metabolism.Human chorionic gonadotropin maintains the corpus luteum during early pregnancy until the placenta has sufficiently developed to produce adequate amounts of progesterone.
