Hello,
Most women with PCOS don't ovulate and thus cannot become pregnant. So the first treatment option for infertility is usually the administration of drugs to induce ovulation like Clomid. Secondly Glucophage or Metformin is an insulin-sensitizing agent that is sometimes used in conjunction with Clomid.
Other than that, Injectable HCG, Hmg, FSH, GnRH and assisted reproduction like IUI, IVF, GIFT AND ICSI may also be used.
