Does body mass index of infertile women have an impact on IVF procedure and outcome?
PURPOSE: The objective was to explore whether body mass index (BMI) of women related to the different parameters of the in vitro fertilization (IVF) procedure and outcome. METHODS: This retrospective study on 398 couples analyzed epidemiological features, characteristics of ovarian stimulation, number and quality of retrieved oocytes, as well as pregnancy outcome according to three groups of BMI values: BMI < 20, 20 < or = BMI < 25 and BMI > or = 25 kg/m2. RESULTS: The prevalence of underweight and overweight women was 21.8% and 22.3%, respectively. The mean ratio follicle-stimulating hormone-luteinizing hormone increased significantly according to BMI. An increase in the mean number of consummated gonadotropin ampoules together with a decrease in the number of collected oocytes was observed in long stimulating protocol cycles when BMI > or = 25 kg/m2. The same observations were made in short stimulation protocol cycles of BMI < 20 and > or = 25 kg/m2. No significant difference could b
