Menogon Side Effects

By Norma Chew ; Updated July 27, 2017

Menogon is a purified combination of follicle stimulating hormone (FSH) and luteinizing hormone (LH) extracted from the urine of post menopausal women. Menogon is administered as an intramuscular or a subcutaneous injection to treat infertility, to induce ovulation and enable pregnancy in women. It may also be used to stimulate the production of sperm in certain forms of male infertility. It’s best to know the function and side effects of Menogon before taking it.


Menogon is used to treat women with infertility problems due to under-active pituitary glands. Menogon contains the hormones FSH and LH that are normally produced by the pituitary gland. Menogon works by stimulating the ovaries to produce eggs. Another hormone called human chronic gonadotropin (hCG) is usually given with Menogan to ensure ovulation will occur at the expected time. Menogon is available by prescription only.
