Clomid is definitely a mouth medication that can become used to trigger ovulation. It works by stopping estrogen receptors during the hypothalamus, which is an important "hormonal controls center" for the figure. Whenever this happens, the hypothalamus is stimulated to launch follicle stimulating hormone (FSH), and luteinizing hormone (LH). These are really the commonly developing ovarian stimulants, which prompt ovulation in a typical cycle.
