Insulin Sensitizers Mainstay of managing insulin resistant PCOS is with insulin sensitizers. Commonest drug used is Metformin. Dose of 1500 –1700mg/day in divided doses. Causes G.I. side effects
Study : 626 infertile women randomly assigned to CC+Placebo Metformin + placebo x 6 months Metformin + Clomiphene 22.5% 7.2% 26.8% 6% 0% 3.1% CONCLUSION Clomiphene is superior to Metformin in achieving live birth in infertile women with PCOS though multiple birth is a complication PPCOS trial (Pregnancy in PCOS Trial) PPCOS trial (Pregnancy in PCOS Trial) Ref : Lagro RS et al N.

Insulin Sensitizers in PCOS Conclusion : - Metformin is an effective treatment for anovulation in women with PCOS - Ovulation rates higher when combined with CC - Reduces risk of OHSS by approximately 75% - ↓ serum E2 levels Contd….. Ref : Lord J M, Flight HK et al. Cocherane syst Rev 2005:3
Other Insulin Sensitizers Rosiglitazone; Piolitazone have been used but associated weight gain, less favorable pregnancy profile and possible cardiovascular risk limit their use for this purpose. Inositols Ref. Cochrane Database Syst. Rev 2010

Conclusions If obese, weight loss, should be recommended prior to initiation of therapy. Hyperandrogenism, Hyperinsulinemia should be looked for in every PCOS woman Ovulation inducing agents and adjuvants should be customized. Use of Metformin improves pregnancy rates when added to the ovulation induction protocol Contd..
Conclusions Use of Metformin and Antagonist help to reduce the risk of OHSS following ovulation induction. ART results in PCOS are comparable to non PCOS pts. AMH levels and AFC can serve as predictive markers for response to COH.
