For women who are unresponsive to clomiphene,the oral hypoglycemic agents like metformin could be of little help, or pioglitazone, may bring resumption of regular cycles
and ovulation. These agents reduce the hyperinsulinemia
and hyperandrogenemia in PCOS.
These are actually medically prescribed medicines for PCOS.As this syndrome is very common in women the case is often individualised and treatment option will be processed and prescribed.Fell free to talk to your Doc.
