Answers
Explanation:
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.
hCG levels are linked to the severity of morning sickness or Hyperemesis gravidarum in pregnant women.
hCG can also be used clinically to induce ovulation in the ovaries as well as testosterone production in the testes.
Human chorionic gonadotropin also plays a role in cellular differentiation/proliferation and may activate apoptosis.
