Human kind or animal kind?

Human chorionic gonadotropin or human chorionic gonadotrophin (hCG) is a glycoprotein hormone produced during pregnancy that is made by the developing embryo after conception and later by the syncytiotrophoblast (part of the placenta).[1][2]. Some tumors make this hormone; measured elevated levels 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 analog of hCG, known as luteinizing hormone (LH), is produced in the pituitary gland of males and females of all ages.[1][3] Since the mid-20th century, hCG has been promoted as a supplement to promote weight loss, though there has been no proof that it is effective or safe     I referenced this site.  http://en.wikipedia.org/wiki/Human_chorionic_gonadotropin
