Clomid is an oral supplement that can be used to stimulate ovulation. It really works by preventing estrogen receptors at the hypothalamus, which is an important "hormonal control location" for the figure. Whenever this happens, the hypothalamus is stimulated to launch follicle stimulating hormone (FSH), and luteinizing hormone (LH). These are really the obviously developing ovarian stimulants, which prompt ovulation in a normal pattern.
