Clomid is definitely an oral supplement that can feel used to stimulate ovulation. It works by preventing estrogen receptors during the hypothalamus, and is an important "hormonal controls centre" for the body. Whenever this happens, the hypothalamus is stimulated to release follicle exciting hormone (FSH), and luteinizing hormone (LH). These tend to be the naturally occurring ovarian stimulants, which prompt ovulation in a normal cycle.
