A molecular model of human chorionic gonadotropin,a glycoprotein hormone produced by the placenta during early pregnancy. HCG helps maintain the corpus luteum during this stage,allowing it to secrete progesterone,thickening the lining of the uterus. During a pregnancy test,HCG levels are measured in the blood or urine and can be used to detect fetal chromosomal abnormalities or birth defects | |
