Lifestyle Therapy and Fertility in Women with PCOS Infertility Treatment in PCOS Richard S. Legro, M. D. Penn State College of Medicine Dept of Ob/Gyn Hershey, PA
l AUTHORS' CONCLUSIONS: No RCTs were located that assessed the effects of preconception advice on the chance of a live birth or other fertility outcomes in people who perceived that they may be infertile and were investigating the possibility of medical treatment to address subfertility.

Can we achieve meaningful weight loss which will improve fertility outcomes?
Limitations of Lifestyle Therapy in Infertility l Dose? u. Is there an ideal rate of weight loss or activity increase l Duration? u. How long should the intervention be instituted l Timing? u. Is the intervention before or during infertility treatment? l Patient Compliance (buy in) u. Will patients be able to follow our instructions

No Difference in Ovulation Rates between Treatment Groups
Summary: Lessons Learned l External Validity u. Many will not even attempt a lifestyle intervention u. Most who do will drop out u. Severely obese patients may be poor candidates for such programs u. There will be hurdles to implementing these programs in our current medical system l Best Case Scenario u. Modest Effects, ? Improved outcomes

NIH consensus: Indications for Bariatric Surgery BMI > 40 l BMI > 35 with serious medical comorbidities l u. Is PCOS and/or infertility a serious medical comorbidity Malcolm, NEJM, 2009
Reproductive Health in Women undergoing Bariatric Surgery l l 1, 538 females having bariatric surgery (NIH-LABS Consortium). PCOS had been diagnosed in 13. 1% of subjects. Women who were obese by 18 years old were more likely to report PCOS and infertility and less likely to have ever been pregnant, compared with women who became obese later in life. Future pregnancy was important to 30. 3% of women younger than 45 years, and overall to 51. 4%. Gosman et al, Fertil Steril, 2009
Clinical and biochemical characteristics of the morbidly obese PCOS patients submitted to bariatric surgery, before and after weight loss Escobar-Morreale, H. F. et al. JCEM 2005
Conclusion: Rates of many adverse maternal and neonatal outcomes may be lower in women who become pregnant after having had bariatric surgery compared with rates in pregnant women who are obese; however, further data are needed from rigorously designed studies.
Can we achieve meaningful weight loss which will improve fertility outcomes? Only with bariatric surgery!
