Elective Single Embryo Transfer (ESET): Safest Pregnancy Option
Elective Single Embryo Transfer (ESET) achieves a 74% pregnancy rate for women under 38, matching 77% twin transfer success while eliminating twin pregnancy risks. Twin pregnancies carry 50% higher premature birth rates and NICU stays, emphasizing ESET’s role in reducing maternal and fetal complications.
Key Takeaways
ESET Success Rates vs. Twin Embryo Transfers: Data from RSC
Women under 38 using ESET (74% pregnancy rate) see near-identical results to twin embryo transfers (77%), but with zero twin pregnancies. Egg donation recipients also maintain 73% success with ESET versus 90% with twins, but at 33% higher twin risk.
Twin Pregnancy Risks: Prematurity and Neonatal Complications
Twin pregnancies increase premature delivery by 4-5 weeks on average, with 50% of RSC patients reporting NICU admissions. Obstetricians often mandate bed rest for twin pregnancies, extending hospitalization costs and emotional strain.
Frozen Embryo Benefits for ESET Patients: Cost and Safety
RSC reports frozen embryo transfers match fresh embryo success rates. Patients with spare blastocysts can pursue cost-effective second attempts, reducing long-term expenses while maintaining single-embryo safety protocols.
