Fertility - Women
HCG, also known as human chorionic gonadotropin, is often used as a fertility medication. HCG injections work by triggering ovulation when there is at least one mature ovarian follicle. This can occur about 36 to 48 hours following the HCG injection. HCG injections are also used to help facilitate pregnancy by sustaining levels of progesterone.
Fertility - Men
HCG injections can also be used for men when they have impotence problems. It can increase sperm count. HCG increases intratesticular testosterone by triggering leydig cells. Men may choose to use HCG injections for hypogonadism.
Weight Loss
HCG injections have also been used to aid in weight loss, however this is experimental, and has not been proven to actually work. It may also be unsafe. Possibly, HCG triggers the hypothalamus into preserving lean muscle and targeting fat deposits instead. This is an unproven theory.
