Success rates vary from clinic to clinic, which means that it’s important for you to find one that is reputable. To help with this, we’ve provided a clinic search that you can use to find great clinics near you.
While we cannot speak for every clinic, we can provide you with the success rates from the information that we have collected from clinics who use our eggs:
- The overall pregnancy rate is approximately 60 percent.
- The elective single embryo transfer pregnancy rate is also about 60 percent.
- The double embryo transfer rate is approximately 70 percent. (Pregnancies from double embryo transfer have a 50 percent chance of being twins, and for this reason Prelude strongly advises single embryo transfer whenever possible.)
NOTE: None of this data is recorded with Center for Disease Control (CDC) or Society for Assisted Reproductive Technology (SART). To date, the CDC and SART registries do not include donor egg treatment cycles from frozen eggs.
Reproductive Biology Associates, a Prelude Partner, has consistently shown pregnancy rates in excess of 60 percent for the last 10 years (except in 2005) in egg donation cycles initiated with fresh donor eggs, and in the transition from primarily “fresh” egg donation to “frozen egg” donation, RBA and now Prelude have not seen any decline in overall pregnancy and delivery rates.
