Human chorionic gonadotropin (hCG) is produced by trophoblasts in pregnancy as well as in gestational trophoblastic diseases (GTD). The alpha subunit is identical to that for luteinizing hormone (LH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH). Elevated serum levels of hCG can lead to complications that include hyperemesis gravidarum, early development of preeclampsia, and occasionally hyperthyroidism.
