Embryo Transfer

Embryo transfer—whether using fresh or thawed embryos, at the cleavage stage or as blastocysts—is a critical IVF step that directly influences implantation and pregnancy success.

The “freeze-all” strategy, which involves cryopreserving embryos for transfer in a later optimized cycle, is increasingly adopted to enhance outcomes and reduce risks like OHSS.

Elective single embryo transfer (eSET) is also gaining popularity, lowering the incidence of multiple pregnancies while maintaining high success rates due to advances in embryo selection and transfer techniques.
