Overview
Brief Summary
This case-control study compares IVF results and live birth rates in women undergoing IVF with a history of bariatric surgery as compared to 2 age-matched control groups composed of (A) non-operated women matched on cases' post-operative BMI (controls 1) and (B) non-operated severely obese women (controls 2).
Detailed Description
A preliminary study in the participating center showed a trend to lower ovarian response to stimulation and live birth rates after bariatric surgery compared to weight-matched patients. However, statistical significance was not reached, as the sample size was small. The aim of the research project is to study the ovarian response and live birth rates of this bariatric surgery population, with a sufficient number of patients, in order to reach higher statistical power. This case-control study will involve 3 IVF (in-vitro fertilization) centers in France . All patients undergoing IVF with a history of bariatric surgery will be included from January 2012. Each case will be matched for BMI and age to the 2 next patients without bariatric surgery history and undergoing IVF and to one non-operated severely obese woman. Surgery procedures include sleeve gastrectomies and by-passes. The IVF results and live birth rates will be compared between the three groups.

Outcomes
Primary Outcomes
Live birth rates
Time Frame: nine months after embryo transfer
number of live births divided by the number of embryo transfers
Secondary Outcomes
- average number of mature oocytes obtained(The day of oocyte retrieval in the case of IVF with sperm injection (ICSI) just after decoronisation, or on day one after oocyte retrieval in classical IVF. Oocyte retrieval occurs 36 hours after hCG injection after an ovarian stimulation protocol.)
