HCG Levels Human chorionic gonadotropin,or hCG is a hormone produced by the placenta after implantation.HCG interacts with the LHCG receptor of the ovary and promotes the maintenance of the corpus luteum during the beginning of pregnancy. Levels of hCG are present throughout pregnancy,the hCG levels will double every
48-72 hours. The level will reach its peak in the first 8-11 weeks of pregnancy and then will decline and level off for the remainder of the pregnancy.
