Egg Freezing Success Rates & Live Birth Probabilities at Shady Grove Fertility
Shady Grove Fertility published egg freezing success rates in Fertility and Sterility, showing 70-80% live birth chances for women under 38 freezing 15-20 eggs. Their study tracked 1,283 frozen eggs across 128 IVF cycles, achieving 51 pregnancies and 55 children.
Key Takeaways
Published Egg Freezing Success Rates in Fertility and Sterility Journal Confirm Comparable Outcomes to Fresh Eggs
Shady Grove Fertility’s 2016 study, published in Fertility and Sterility, demonstrated that IVF with frozen eggs achieves similar pregnancy rates to fresh eggs. Of 128 cycles using frozen eggs, 51 resulted in pregnancies, validating long-term viability of egg freezing technology.
Age-Specific Egg Freezing Recommendations for Optimal Live Birth Chances
Women under 38 should freeze 15-20 mature eggs for a 70-80% live birth probability, while women 38-40 need 25-30 eggs for 65-75% success. These guidelines are based on 1,171 cycles analyzed in the study.
Live Birth Probability Increases with More Eggs Frozen: 15-20 Eggs at Age 30-34 Give 70-80% Chance
The study found women aged 30-34 who froze 15-20 eggs had 70-80% likelihood of at least one live birth. Success rates decline with age and fewer eggs stored, emphasizing the importance of freezing eggs at younger ages.
Comprehensive Study Includes Elective and Medically Indicated Egg Freezing Cases for Accurate Success Rate Analysis
The research evaluated four patient groups: elective freezers, cancer patients, and couples choosing not to fertilize all eggs. This multi-faceted approach tracked outcomes from egg thawing to live births across 128 cycles.
128 IVF Cycles Resulted in 55 Children and 8 Ongoing Pregnancies from Frozen Eggs as of January 2015
From 117 women returning for IVF after egg freezing, 51 pregnancies occurred (12 twins, 39 singletons), resulting in 55 children and 8 additional pregnancies. 62 high-quality blastocysts remained frozen for future attempts.
