Human Chorionic Gonadotrophin, commonly known as hCG, is a hormone produced during pregnancy. It is often used as an indicator for pregnancy testing. However, there are other names for this hormone, such as choriogonadotropin, chorionic gonadotropin, and pregnancy hormone. The hormone is produced by cells that form the placenta in women. Moreover, despite its reproductive role, there are some non-reproductive effects of hCG. In some cases, it has been proven to suppress hunger as well as testosterone levels. Overall, the hormone plays an essential role in maintaining pregnancy, and its various names exist to improve communication in the scientific and medical community.
