Clomid is definitely an oral supplement that can become used to stimulate ovulation. It really works by stopping estrogen receptors at the hypothalamus, which is an important "hormonal control center" for the body. Whenever this occurs, the hypothalamus is stimulated to launch follicle exciting hormone (FSH), and luteinizing hormone (LH). These tend to be the commonly developing ovarian stimulants, which prompt ovulation in a typical routine.
