Abstract:
BACKGROUND: Whether overweight and obesity have impact on the outcome of in vitro fertilization and embryo transfer (IVF-ET) treatment remains poorly understood.OBJECTIVE: To investigate the effect of women's body mass index (BMI) on the outcome of IVF-ET treatment. METHODS: A total of 184 cases were divided into 3 groups according to BMI: lankness group (BMI < 18.5 kg/m2), normal group (18.5kg/m2 ≤ BMI < 24 kg/m2), overweight and obesity group (BMI≥ 24 kg/m2). Treatments of ovulation induction and IVF-ET were regularly performed in the Reproductive Medical Center, Renmin Hospital of Wuhan University. The duration and dose of gonadotrophic hormone (GTH) treatment, estradiol level at the day of human chorionic gonadotropin (hCG) injection, and the differences of retrieved oocytes numbers, fertility rate, embryo quality, implantation rate, pregnancy rate and abortion rate were compared.RESULTS AND CONCLUSION: The dose of GTH used was in the overweight and obesity group was greater than that of the other groups (P< 0.05), and the dose was increased with BMI increasing. There was no significant difference in other aspects such as estradiol level, retrieved oocytes numbers, fertility rate, embryo quality, implantation rate, pregnancy rate and abortion rate at the day of hCG injection among the three groups (P> 0.05). All results demonstrated that overweight and obese patients require a higher hCG dose to achieve follicular maturation than normal weight patients. However, overweight and obesity does not affect negatively results of IVF-ET.
