I was interviewed this year for a research project about freezing eggs to preserve female fertility - even though that wasn't the reason we did the freezing. As far as the researcher knew, she thought I was probably the only person to have gone back and used the frozen eggs so far in Australia, and we did that in 2010. Since we had 7 fresh and 7 frozen eggs ICSI'd that cycle it made it easy to compare the results directly.
Lost 1/8 frozen in the thaw,
Fert 40% frozen vs 100% fresh,
0 blasts vs 2 dud blasts with no ICM
0 suitable for transfer vs 1 morula transferred (FS was sad because he really wanted to write up a pregnancy from frozen)
0 for freezing from either set
