where is human chorionic gonadotropin (hcg) produced
Human chorionic gonadotropin Human chorionic gonadotropin (hCG) is a hormone produced by the placenta after implantation.[1][2] The presence of hCG is detected in some pregnancy tests (HCG pregnancy strip tests). Some cancerous tumors produce this hormone; therefore, elevated levels measured when the patient is not pregnant may lead to a cancer diagnosis and, if high enough, paraneoplastic syndromes, however, it is not known whether this production is a contributing cause, or an effect of carcinogenesis. The pituitary analog of hCG, known as luteinizing hormone (LH), is produced in the pituitary gland of males and females of all ages.[1][3]
