OBJECTIVE: Associations between parental pre-pregnancy BMI in IVF/ICSI fresh embryo transfer cycles and neonatal outcomes were investigated through a retrospective analysis.
METHODS: A retrospective analysis of Couples who underwent IVF/ICSI fresh embryo transfer 1340 cycles from January 2019 to December 2021 was conducted in the Department of Reproductive Medicine of our hospital. Based on the preconception BMI of parents, they were divided into four groups: Group A (both father and mother with BMI < 25 kg/m²), Group B (father with BMI < 25 kg/m² and mother with BMI ≥ 25 kg/m²), Group C (father with BMI ≥ 25 kg/m² and mother with BMI < 25 kg/m²), and Group D (both father and mother with BMI ≥ 25 kg/m²). The differences in baseline characteristics, fertilization and embryo development, pregnancy outcomes, and neonatal outcomes were compared among the groups.
RESULTS: In the IVF cycles, Group A had a higher rate of normal fertilization compared to three other groups, Group A is significantly higher than Group D, with statistical significance (P < .05). In the ICSI cycles, there were no significant differences among the four groups regarding normal fertilization rate, day 3 high-quality embryo rate, blastocyst formation rate, and high blastocyst rate. Univariate and multivariate analysis results showed no significant differences in clinical pregnancy and live birth rates among the four groups. However, Group D had a significantly higher rate of preterm birth than other three groups, with statistical significance (P < .05).
CONCLUSION: To achieve better clinical outcomes and neonatal outcomes, overweight or obese couples should lose weight before undergoing IVF/ICSI treatment.
