Elevated body mass index in modified natural cycle frozen euploid embryo transfers is not associated with live birth rate

Purpose To assess the impact of elevated BMI on the success of modified natural cycle frozen embryo transfers (mNC-FET) of euploid embryos. Methods This retrospective cohort study at a single academic institution reviewed mNC-FET involving single euploid blastocysts from 2016 to 2020. Comparison gro...

Description
Summary:Purpose To assess the impact of elevated BMI on the success of modified natural cycle frozen embryo transfers (mNC-FET) of euploid embryos. Methods This retrospective cohort study at a single academic institution reviewed mNC-FET involving single euploid blastocysts from 2016 to 2020. Comparison groups were divided by pre-pregnancy BMI (kg/m 2 ) category: normal weight (18.5–24.9), overweight (25–29.9) or obese (≥ 30). Underweight BMI (
