Clomid is often a first line treatment to induce regular ovulation. Clomid works at the level of the hypothalamus where it competes for estrogen binding sites. When these \"sites are occupied\" by Clomid, the hypothalamus responds by producing more GnRH which then stimulates the pituitary to produce FSH. Remember, in a normal cycle healthy follicles produce estrogen, which signals the hypothalamus to reduce production of FSH. Clomiphene is marketed in the United States by Aventis Laboratories as Clomid and by Serono Laboratories as Serophene.
