Abstract
ObjectivesTo evaluate the influence of overweight and obesity on the results of the first in vitro fertilization attempt, without or with intracytoplasmic microinjection (IVF/ICSI), in terms of live births. MethodsRetrospective observational study concerning the first IVF/ICSI attempts from 01/01/2006 to 31/12/2017 carried out at the Assisted Reproductive Technology of the CHU of Besançon, studying the delivery rate (excluding frozen embryos transfers), and the data of Assisted Reproductive Technology attempts, in overweight (BMI 25 to 29.9kg/m2) and obese women (BMI≥30kg/m2), compared to women with a standard BMI (18 to 24.9kg/m2). ResultsA total of 3192 patients were included. At the end of their first IVF/ICSI attempt, the delivery rate of women with standard BMI was 34.7%. The delivery rate was significantly lower in overweight women (29.5%, p=0.011) and comparable in obese women (32.4%, p=0.476). The birth rate of women with a BMI≥25 kg/m2 was also significantly lower than that of women with a standard BMI (30.4% versus 34.7%, p=0.019). After multivariate analysis, the delivery rate in overweight patients remained significantly lower compared to the population with standard BMI (OR=0.707; 95% CI 0.561–0.890), and comparable in obese patients (OR=0.796; 95% CI 0.585–1.084). ConclusionThe delivery rate was lower in overweight women, whereas it was not significantly different in obese women.
