Success rates with frozen eggs

Dear Dr Smith,

My good friend is 40 years old and would dearly love to have a child/children. Her problem is that she doesn't have a permanent partner and is reluctant to go it alone.

She is keep to pursue a stim cycle to retrieve and freeze her eggs.

What are the thaw rates and live birth rates from frozen eggs. I've heard that the stats aren't that good...

Many thanks for your advice

Although the methodology for egg freezing is evolving and improving, its not quite ready for prime time. Egg freezing is still considered experimental and you are correct that the reports of pregnancy from frozen-thawed eggs are sporadic and few. Since the rate limiting step is how we freeze the eggs, the logic that you should bank now and hope that the technology improves by the time you are ready to thaw is flawed. Since they were already frozen with a sub-optimal method, the post-thaw survival rate will be low.

Another option is to use donor sperm to generate embryos. Embryos freeze and thaw much better than eggs. So, if she's considering banking on the possibility of getting prenant with or without Mr Right, this would be my suggestion.
