Chorionic gonadotropin injections need to be injected intramuscularly, and the injection site is mainly in the outer upper 1/4 of the buttocks, i.e. the gluteus maximus muscle.
Chorionic gonadotropin for injection, a sterile powder for injection, is available in sizes of 500 units, 1,000 units, 2,000 units and 5,000 units per injection. The site of intramuscular injection can be the gluteus maximus, followed by the gluteus medius, gluteus minimus, lateral femoral and deltoid muscles.
Chorionic gonadotropin is often used for anovulatory infertility in women due to pituitary gonadotropin insufficiency, often in combination with urogonadotropin to promote follicular maturation and ovulation; for in vitro fertilization to obtain multiple eggs, which needs to be used in combination with urogonadotropin; for the treatment of luteal insufficiency in women; for functional uterine bleeding, early preeclampsia in pregnancy, habitual miscarriage, and so on.
Chorionic gonadotropin is contraindicated in patients with inflammatory diseases of the reproductive system, hormonally active adenocarcinoma, and asexual glands (congenital or post-surgical). Moreover, chorionic gonadotropin should not be used for a long period of time to avoid the production of antibodies and inhibition of pituitary gonadotropic function.
Specific dosing regimen should be under medical supervision.
