Abstract
Elevated body mass index (BMI) has been associated with an increased risk of pregnancy loss; yet, the degree to which factors such as aneuploidy contribute to these losses has not been quantified1-3. A retrospective study demonstrated an elevated risk of loss among obese patients with normal cytogenetic testing of products of conception (POC). That study only assessed pregnancy losses in which POC were available for testing, potentially introducing bias to patient selection4. Evaluating patients undergoing IVF with euploid embryo transfer allows for a unique assessment of the impact of obesity on pregnancy loss by controlling for ploidy.
