Embryo Transfer

Embryo transfer—whether ‘fresh’ or ‘thawed’, and using cleavage-stage embryos or blastocysts—is a crucial step in IVF, directly impacting implantation and pregnancy outcomes. The “freeze-all” strategy, where embryos are cryopreserved for transfer in a later, optimized cycle, has gained traction for improving success rates and reducing risks like OHSS. Elective single embryo transfer (eSET) is also on the rise, helping lower the chance of multiple pregnancies while maintaining high success rates due to advances in embryo selection and transfer techniques.
