What is HCG?

Pregnyl is a hormone that is used to cause ovulation and to treat infertility in women. Pregnyl is not effective in women with primary ovarian failure.

HCG is used in men to treat hypogonadism, a condition in which the body doesn't produce enough testosterone.

HCG is also used in young boys whose testicles have not descended (dropped) into the scrotum as normally expected during growth. HCG is usually given for this condition in boys who are 4 to 9 years old.

HCG is not approved as an aid to weight loss and has not been proven to be more effective than reducing calories in the diet.

HCG may also be used for purposes not listed in this medication guide.

Warnings

HCG can cause serious side effects. Call your doctor at once if you have: severe stomach pain or bloating, swelling, rapid weight gain, chest pain, trouble breathing, severe nausea and vomiting, decreased urination, pain or swelling in one leg, or sudden numbness on one side of the body.
