First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether using a special freezing medium designed just for eggs, versus a universal medium for all stages, affects pregnancy rates in egg donation. Researchers analyzed data from 111 donor cycles. The goal is to see if the type of freezing medium makes a difference in how many eggs survive thawing and lead to a pregnancy.
