Human chorionic gonadotropin (hCG) is a hormone primarily produced by the placenta during pregnancy. Often called the "pregnancy hormone," it is what home pregnancy tests detect in urine to confirm conception.
Primary Functions and Medical Uses
Female Fertility: It acts as a "trigger shot" to induce ovulation by mimicking the mid-cycle surge of luteinizing hormone (LH). It also supports the corpus luteum in producing progesterone, which is essential for maintaining a pregnancy.
Male Health: In men, hCG injections can stimulate the Leydig cells in the testes to produce testosterone and support sperm production. It is often used to treat hypogonadism or to prevent testicular atrophy during testosterone replacement therapy.
Pediatric Use: It is used to treat cryptorchidism (undescended testicles) in young boys by encouraging the testes to move into the scrotum.
Tumor Marker: Elevated hCG levels in non-pregnant individuals can be a diagnostic marker for certain cancers, including testicular and ovarian germ cell tumors or gestational trophoblastic disease (molar pregnancy).
