Chorionic gonadotropin (CG) has the same effects as ......... secreted by anterior pituitary.

Answer 1

Chorionic gonadotropin (CG) has the same effects as luteinizing hormone (LH) secreted by the anterior pituitary.

Both hormones are recognized by the luteinizing hormone/choriogonadotropin receptor (LHCGR), which is located in the ovaries, uterus, and breasts. LH causes conversion of the residual follicle into a corpus luteum that, in turn, produces progesterone to prepare the endometrium for possible implantation. LH is necessary to maintain luteal function for the second two weeks of the menstrual cycle. If pregnancy occurs, LH levels will decrease, and luteal function will instead be maintained by the action of hCG (human chorionic gonadotropin), a hormone very similar to LH but secreted from the new placenta.
