Chorionic Gonadotropin (Systemic)
In the U.S.-
Another commonly used name is human chorionic gonadotropin (hCG).
Chorionic gonadotropin (kor-ee-ON-ik goe-NAD-oh-troe-pin) is a drug whose actions are almost the same as those of luteinizing (loo-te-in-eye-ZING) hormone (LH), which is produced by the pituitary gland. It is a hormone also normally produced by the placenta in pregnancy. Chorionic gonadotropin has different uses for females and males.
In females, chorionic gonadotropin is used to help conception occur. It is usually given in combination with other drugs such as menotropins and urofollitropin. Many women being treated with these drugs usually have already tried clomiphene alone (e.g., Serophene) and have not been able to conceive yet. Chorionic gonadotropin is also used in in vitro fertilization (IVF) programs.
In males, LH and chorionic gonadotropin stimulate the testes to produce male hormones such as testosterone. Testosterone causes the enlargement of the penis and testes and the growth of pubic and underarm hair. It also increases the production of sperm.
Although chorionic gonadotropin has been prescribed to help some patients lose weight, it should never be used this way. When used improperly, chorionic gonadotropin can cause serious problems.
Chorionic gonadotropin is to be administered only by or under the immediate supervision of your doctor. It is available in the following dosage form:

Pregnancy- If you become pregnant as a result of using this medicine with menotropins (e.g., Pergonal) or urofollitropin (e.g., Metrodin), there is an increased chance of a multiple pregnancy (for example, twins, triplets).
Children- Chorionic gonadotropin, when used for treating cryptorchidism (a birth defect where the testes remain inside the body), has caused the sexual organs of some male children to develop too rapidly.
Other medicines- Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your health care professional if you are taking any prescription or nonprescription (over-the-counter [OTC]) medicine.
