Coasting refers to witholding exogenous gonodotropine usage and delaying the administration of hCG in high risk cycles until serum estradiol levels falls into an acceptable range. The aim of our study is to evaluate coasting effect on IVF oucomes in patients with E2 levels of 4000-5000 pikogram. Method: This study was a single centered, retrospective and a case-control study. Study population were selected from women applied Zeynep Kamil Research Hospital IVF department between January 2003 and December 2013 n:7850 . Patients were divided in 2 groups as conrol group Group 1, n:48 and coasted group Group 2, n:34 according to whether or not coasting performed. Results: E2 levels on the day of hCG in group 2 were significiantly lower than group 1 4332.6±256.6 and 3180.8±702.9; p KW - Coasting KW - in-vitro fertilization KW - E2 levels CR - 1.Aljawoan FY, Hunt LP, Gordon UD.
