Title: Human Chorionic Gonadotropin Molecule
Caption: 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.
