Pre-pregnancy obesity is not associated with poor outcomes in fresh transfer in vitro fertilization cycles: a retrospective study.

ABSTRACT:

Purpose

The impact of body mass index (BMI) on in vitro fertilization (IVF) has been well acknowledged; however, the reported conclusions are still incongruent. This study aimed to investigate the effect of BMI on IVF embryos and fresh transfer clinical outcomes.

Methods

This retrospective cohort analysis included patients who underwent IVF/ICSI treatment and fresh embryo transfer from 2014 to March 2022. Patients were divided into the underweight group: BMI < 18.5 kg/m²; normal group: 18.5 ≤ BMI < 24 kg/m²; overweight group: 24 ≤ BMI < 28 kg/m²; and obesity group: BMI ≥ 28 kg/m². A generalized linear model was used to analyze the impact of BMI on each IVF outcome used as a continuous variable.

Results

A total of 3465 IVF/IC
