About HCG Pregnyl
Chorionic gonadotropin is a drug whose actions are almost the same as those of luteinizing 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.
Usage and Dosing
The dose of chorionic gonadotropin will be different for different patients. The following information includes only the average doses for chorionic gonadotropin. If your dose is different, do not change it unless your doctor tells you to do so.
The number of doses you receive each day, the time allowed between doses, and the length of time you receive the medicine depend on the medical problem for which you are receiving chorionic gonadotropin .
- For injection dosage form:
- For treating men with problems related to low levels of male hormones:
- Adults—1000 to 4000 Units injected into the muscle two to three times a week. You may need to receive this medicine for several weeks, months, or longer. If you are being treated for a low sperm count and have been on this medicine for six months, your doctor may give you another hormone medicine (menotropin or urofollitropin injection). You may need to receive both of these medicines together for up to twelve more months.
