Human chorionic gonadotropin has all the following functions EXCEPT
A) it develops the chorion, which will form the placenta
B) it provides feedback to the pituitary indicating pregnancy and FSH and LH are no longer required
C) it maintains the corpus Luteum for 3 months
D) it regulates the release of estrogen and progesterone during early pregnancy

I think it's A?

Hey Angie19,

Human chorionic gonadotropin interacts with the LHCG receptor of the ovary and promotes the maintenance of the corpus luteum during the beginning of pregnancy.

This allows the corpus luteum to secrete the hormone progesterone during the first trimester. Progesterone enriches the uterus with a thick lining of blood vessels and capillaries so that it can sustain the growing fetus.

Due to its highly negative charge, hCG may repel the immune cells of the mother, protecting the fetus during the first trimester.
Because of its similarity to LH, hCG can also be used clinically to induce ovulation in the ovaries as well as testosterone production in the testes. As the most abundant biological source is women who are presently pregnant, some organizations collect urine from pregnant women to extract hCG for use in fertility treatment.
