Proven was more important to me too...(success mentioned)

I used an in-house donor who was 32 nearing 33. She provided us with 41 eggs of which 29 fertilized. I got pregnant on my fresh transfer and we were lucky to get 25 frosties. I am currently pregnant with twins from my first frozen transfer and we still have 20 frosties. I know I am extremely blessed and my results are very, very, very far from normal. Using an "older" donor worked out well for us.
Good luck with your decision. I know it is a tough one. Once I made my decision I never looked back. And honestly, I rarely think about the fact that I had to go the DE route. I have the child I was supposed to have - and she is awesome!
