Clomid is actually an oral medication that can become used to stimulate ovulation. It really works by blocking estrogen receptors at the hypothalamus, and that is an important "hormonal control centre" for the figure. When this occurs, the hypothalamus is stimulated to release follicle exciting hormone (FSH), and luteinizing hormone (LH). These are really the naturally taking place ovarian stimulants, which prompt ovulation in a typical pattern.
