Egg Freezing Success Rates at Shady Grove Fertility Revealed
Shady Grove Fertility’s 2016 study, published in *Fertility and Sterility*, reports that 51 pregnancies resulted from 128 IVF cycles using frozen eggs, with 55 live births and 8 ongoing pregnancies. Success rates correlate with age and egg count: women under 38 with 15–20 frozen eggs have a 70–80% chance of live birth, while those 38–40 years old with 25–30 eggs have a 65–75% chance.
Key Takeaways
Egg Freezing Success Rates by Age and Egg Count at Shady Grove Fertility
Data from 1,171 egg freezing cycles (2009–2014) shows that live birth rates depend on both age and the number of eggs preserved. Women aged 30–34 with 15–20 eggs have the highest predicted success rates, while older patients require more eggs for comparable outcomes.
Recommended Egg Counts for Optimal Pregnancy Outcomes in Egg Freezing
Shady Grove Fertility advises 15–20 mature eggs for women under 38 (70–80% live birth chance) and 25–30 eggs for those 38–40 (65–75% live birth chance). These thresholds are based on statistical models predicting cumulative birth probabilities.
Live Birth Probabilities from Frozen Eggs: Shady Grove Fertility Study Findings
Of 128 IVF cycles using frozen eggs, 51 pregnancies occurred, including 55 live births and 8 ongoing pregnancies. The study confirms frozen egg IVF performs equally well as fresh egg IVF, with 12 twin pregnancies reported.
Comparing Frozen vs. Fresh Egg IVF Success Rates
The study validates that frozen egg IVF cycles achieve similar success rates to fresh cycles, with 32 cycles from elective egg freezing resulting in pregnancy. This challenges earlier assumptions about frozen egg viability.
Factors Influencing Egg Freezing Success Rates and Future Planning
Success hinges on age at egg retrieval, egg count, and individual goals. The study included elective, medically indicated, and cancer-related cases, emphasizing personalized planning for fertility preservation strategies.
