The online scientific research journal Futurity published our findings showing fresh donor eggs have a statistically significant advantage in birth outcomes compared with frozen donated eggs
The international journal Futurity carried a story about our national study published in the journal Obstetrics & Gynecology that was the largest head-to-head comparison of the two IVF (in vitro fertilization) approaches. It measured the likelihood of a good perinatal outcome, defined as a single baby without prematurity and with a healthy birth weight, when using fresh donor eggs and frozen donor eggs.
Our Dr. Alex Polotsky was senior author of the research that studied three years of data from the Society for Assisted Reproductive Technology. Nearly 37,000 IVF attempts were analyzed, including 8,381 (22.7%) that used frozen eggs and 28,544 (77.3%) using fresh.
“It’s important for physicians and their patients to understand the risks and benefits of using either fresh or frozen eggs,” says lead author Dr. Jennifer L. Eaton, medical director of assisted reproductive technology and director of the Oocyte Donation Program at the Duke Fertility Center. “This study provides the best data to date, showing a slight advantage to using fresh eggs. Physicians should weigh this new finding against the known advantages of frozen eggs when counseling their patients.”
