Using Clomid to treat infertility

Question:

What is the success rate of using Clomid for infertility? Is there a risk of multiple births?

Answer:

Clomid is the brand name of the drug clomiphene, which is used to stimulate the ovary to release an egg. It is used to treat women who are infertile because they have no ovulation or infrequent ovulation. Clomiphene stimulates molecules inside of cells that are normally stimulated by the hormone estrogen. One important function of these molecules is controlling the steps that lead to ovulation.
