In molecular biology, human chorionic gonadotropin (hCG) is a hormone produced during pregnancy that is made by the developing placenta after conception, and later by the placental component syncytiotrophoblast. 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. As of December 6, 2011 (2011 -12-06), the FDA has prohibited the sale of "homeopathic" and over the counter hCG diet products and declared them fraudulent and illegal.

“Pessimists are the people who have no hope for themselves or for others. Pessimists are also people who think the human race is beneath their notice, that they’re better than other human beings.”
