Single or Double Embryo Transfer for Infertility: An Evaluation of Registry Data From Over 22 000 Treatment Cycles.

Key Points

• This research aims to compare the effectiveness and risks of single versus double embryo transfer in infertility treatments.
• Analysis of registry data from over 22,000 treatment cycles
• Comparison of success rates between single embryo transfer (SET) and double embryo transfer (DET)
• Assessment of associated risks with each transfer method.
• Two consecutive single embryo transfers show similar success rates to double embryo transfer
• SET significantly reduces risks compared to DET while maintaining comparable birth outcomes.
