VILARINO, Fabia Lima; BIANCO, Bianca; CHRISTOFOLINI, Denise Maria  and  BARBOSA, Caio Parente. Impact of body mass index on in vitro fertilization outcomes. Rev. Bras. Ginecol. Obstet. [online]. 2010, vol.32, n.11, pp.536-540. ISSN 0100-7203.

PURPOSE: to evaluate the impact of body mass index (BMI) on in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes performed at the Human Reproduction Center of Faculdade de Medicina do ABC. METHODS: retrospective data from 488 IVF cycles of 385 patients. Patients were classified into two groups according to BMI: normal weight (18.5-24.9 kg/m2) and overweight/obesity (>25 kg/m2). We evaluated the dose of recombinant follicle stimulating hormone (FSHr), the cancellation rates for ovarian cycle response, and the results of the assisted reproduction laboratory such as number of oocytes, number of good quality embryos, number of embryos transferred, and pregnancy rates, chemical pregnancy rates, miscarriage rate and live birth rate. The t test was used for comparison of quantitative variables between groups, and the χ2 test for comparison between qualitative variables. P values <0.05 were considered significant. RESULTS: considering ovulation induction characteristics, there was no statistically significant difference between groups regarding the FSHr dose administered or the cancellation rates, p=0.47 and p=0.85, respectively. Regarding laboratory findings, the number of oocytes retrieved per cycle was similar for both groups (p=0.09), as also was the number of good quality embryos obtained and transferred (p=0.7 and p=0.6). The pregnancy rate per embryo transfer was 27.6% for the group of normal weight and 29.6% for the overweight/obese group (p=0.76). Miscarriage rates and birth rates were similar for both groups, p=0.54 and p=0.94. CONCLUSION: BMI did not influence IVF/ICSI outcomes evaluated.
