HCG is a hormone used in boys (before puberty) to cause the normal dropping of the testicles into the scrotum. It is also used in certain boys to help with normal sexual development. It works by causing the testes to release male sex hormones (e.g., testosterone).
HCG – Fertigyn is also used in women to treat fertility problems. It is given after finishing another medication (menotropins) to cause the release of an egg (ovulation). It should not be used in women whose ovaries no longer make eggs properly (primary ovarian failure). This medication has not been shown to be effective for weight loss and should not be used for this purpose.
