Body mass index (BMI) does not impact endometrial receptivity in fresh IVF cycles: evaluation of implantation rates (IR) and ongoing pregnancy rates (PR) following the transfer of euploid blastocysts

      Increasing BMI has been associated with reduced implantation and delivery rates in women attempting conception through IVF. While many factors may contribute, altered endometrial receptivity may contribute to this diminution but has been difficult to study in fresh IVF cycles secondary to the complexity of controlling for embryo quality. Recent data show increased implantation rates amongst euploid embryos which are equivalent at all maternal ages through 42 years. This study seeks to investigate the relationship between BMI and endometrial receptivity by considering the implantation rates following the transfer of euploid blastocysts.
