HCG is more than a hormone used to test for confirmation of pregnancy. It is used by the body in many vital pregnancy functions. HCG functions include:
- maintaining production of progesterone by the corpus luteum
- maintaining the endometrium during the first trimester
- stimulates fetal gonad development and androgen synthesis by the fetal testes
- stimulates secretion of estrogen and development of the placenta
If a woman's HCG levels remain low, this can inhibit proper ovulation and fetal development during pregnancy. Often times doctors will test HCG levels to see if a fetus is functioning normally. HCG injections can be administered to aid in ovulation and fetal development.
