Clomiphene (also known as clomifene) is the active ingredient of Clomid, Fertomid and ClomiHexal.
General Information
Clomiphene is a fertility medication prescribed to stimulate ovulation (the release of an egg from an ovary during the menstrual cycle) in women who ovulate infrequently, or are not ovulating at all.
Prior to treatment a semen analysis should be performed to rule out male-infertility.
Multiple pregnancies (a pregnancy where there are two or more foetuses developing in the uterus at the same time) occur frequently in women treated with clomiphene. To rule out the possibility of twins, your doctor should monitor you closely.
How does clomiphene work?
After taking clomiphene a release of follicle-stimulating hormone and luteinizing hormone is triggered. These hormones are important for the development and maturation of the ovarian follicle.
