When I was cycling in Sept 2010, the RE I was with at the time told me that Celine tried and tried and finally was successful w/ DE. I did not ask or question him as I was so focused on myself at the time. I think he shared this w/ me as I was doing a SET of a 5-6 cell that did not look great and he knew it was my last shot w/ OE.
I remember posting this info on one of these boards and some ladies were angry at my RE for saying such info when he did not treat her. I have no idea how he really knew or if he was just guessing.
Her babies are cute and lovely so she wins in the end regardless of OE or DE.
