How does this medication work? What will it do for me?
Menotropins are a mixture of naturally occurring hormones that include follicle stimulating hormone (FSH) and luteinizing hormone (LH). Menotropins are used to treat certain types of infertility in women. Menotropins works by stimulating the ovaries to produce eggs.
Menotropins are usually given with human chorionic gonadotropin (hCG), which is a hormone that works similarly to LH and helps to ensure that ovulation occurs at the expected time.
