Single Embryo Transfer (SET) & IVF Success Rates: What You Need to Know

Single Embryo Transfer (SET) reduces multiple pregnancy risks by transferring one embryo. Genetic testing (PGT-A) ensures embryo viability, as shown in a 2013 RMA study proving equal success rates compared to multiple untested embryos.

Key Takeaways

Understanding SET: IVF’s Revolutionary Single Embryo Transfer Method

SET involves transferring one embryo during IVF, a practice now standard due to improved pregnancy safety and success rates. Unlike older methods requiring multiple embryos, SET minimizes risks like twins/triplets while maintaining high outcomes.

Risks of Transferring Multiple Embryos in IVF

Historically, transferring two or more embryos increased multiple gestation rates, leading to preterm birth, low birth weight, and NICU stays. SET eliminates these risks by prioritizing singleton pregnancies.

Genetic Testing (PGT-A) and Embryo Selection

Preimplantation Genetic Testing for Aneuploidy (PGT-A) identifies chromosomally normal embryos. A 2013 RMA study confirmed transferring one PGT-A-verified embryo achieves the same success rate as transferring two untested embryos.

Technological Advancements Enabling Safe SET

Improved embryo freezing and lab techniques now allow single embryos to survive cryopreservation and implant reliably. This enables SET even without genetic testing, preserving future embryo potential.

Why SET Is Now the Standard of Care in Fertility

SET benefits mothers and children by reducing pregnancy complications while maintaining high success rates. It aligns with modern IVF goals of safer, healthier outcomes for families.
