Pregnyl 5000iu 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).
This medication 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).
