Clomid is definitely an oral medication that can be used to stimulate ovulation. It really works by stopping estrogen receptors at the hypothalamus, and is an important "hormonal controls building" for the body. When this occurs, the hypothalamus is stimulated to launch follicle exciting hormone (FSH), and luteinizing hormone (LH). These are the naturally taking place ovarian stimulants, which prompt ovulation in a typical pattern.
