HCG

Research summary

Human chorionic gonadotropin (HCG) is a glycoprotein hormone, naturally produced by placental tissue during pregnancy, studied clinically for its role in ovarian and testicular function, including stimulating the corpus luteum and supporting gonadal hormone production.

In reproductive-medicine research, HCG is a long-established component of ovarian stimulation protocols; studies adding low-dose HCG to standard stimulation regimens found less gonadotropin was needed and reported higher fertilization rates. HCG is also used clinically as a pregnancy-test analyte and, in oncology research, as a tumor marker for certain cancers including testicular and gestational trophoblastic disease.
