hCG
Also Known As: hCG, human chorionic gonadotropin, 001 hCG
In molecular biology, human chorionic gonadotropin (hCG) is a hormone produced by the syncytiotrophoblast, a component of the fertilized egg, after conception. Following implantation, the syncytiotrophoblast gives rise to the placenta.[1][2] Some cancerous tumors produce this hormone; therefore, elevated levels measured when the patient is not pregnant can lead to a cancer diagnosis. However, it is not known whether this production is a contributing cause or an effect of tumorigenesis. The pituitary analogue of hCG, known as luteinizing hormone(LH), is produced in the pituitary gland of males and females of all ages.[1][3] As of December 6, 2011, the United States FDA has prohibited the sale of "homeopathic" and over the counter hCG diet products and declared them fraudulent and illegal.[4][5][6]
