Human chorionic gonadotropin (hCG) levels in blood footnote 2; Men and non-pregnant women: Less than 5 international units per litre (IU/L) Pregnant women, 1 week of gestation (about 3 weeks after the last menstrual period): 5–50 IU/L. Pregnant women, 2 weeks of gestation (about 4 weeks after the LMP): 50–500 IU/L . Pregnant women, 3 weeks of gestation (about 5 weeks after the LMP): 100 . Human chorionic gonadotropin (hCG) is a glycoprotein that consists of an alpha and beta subunit. The alpha subunit is structurally similar to the alpha subunits of FSH, LH and TSH. The beta subunit is distinct for hCG. The release of hCG into maternal circulation begins with embryo implantation 5 to 7 days after fertilization.. Human chorionic gonadotropin (hCG) is a hormone produced by cells that are surrounding a growing embryo (syncitiotrophoblast initially), which eventually forms the placenta after implantation. The presence of hCG is detected in some pregnancy tests (HCG pregnancy strip tests).. The luteinizing hormone/choriogonadotropin receptor (LHCGR), also lutropin/choriogonadotropin receptor (LCGR) or luteinizing hormone receptor (LHR) is a transmembrane receptor found predominantly in the ovary and testis, but also many extragonadal organs such as the uterus and breasts.The receptor interacts with both luteinizing hormone (LH) and chorionic gonadotropins (such as hCG in humans . Beta hCG Levels in Early Pregnancy Human Chorionic Gonadotropin which is commonly known as hCG is an important hormone especially during early pregnancy. Guideline to hCG levels during pregnancy: hCG levels in weeks from LMP (gestational age)* : 3 weeks LMP: 5 - 50 mIU/ml. In a man, hCG levels may be measured to help see if he has cancer of the testicles. The range of hCG levels just before .
