Description

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 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.

Parenteral
