The single-embryo conundrum: closing the pregnancy rate gap in IVF
A comprehensive review in the International Journal of Gynecology & Obstetrics examines the persistent challenge of multiple pregnancies in in vitro fertilization (IVF). Despite global initiatives to promote single embryo transfer (SET) to avoid the significant health risks of twins or triplets, its adoption is hampered by a lower clinical pregnancy rate compared to double embryo transfer. The analysis identifies the core issue as the imperfect assessment of embryonic developmental potential. The review highlights two promising technological avenues to resolve this: the integration of time-lapse imaging with artificial intelligence for objective embryo evaluation, and advances in molecular biology like non-invasive preimplantation genetic testing. While no definitive solution has yet emerged, the systematic refinement of these tools is seen as key to optimizing SET success rates and addressing the multiple pregnancy dilemma at its source.
Why it might matter to you: For clinicians and researchers in assisted reproductive technology, this review provides a clear strategic roadmap. It underscores that improving embryo selection is the fundamental lever for increasing the uptake of single embryo transfer in clinical practice. Staying informed on the validation of AI and molecular screening tools will be crucial for making evidence-based decisions that improve IVF outcomes while minimizing patient risk.
