I did high stim for my first 3 cycles which all ended in BFN and like you I had from 7-9 eggs each time. I even did CGH on my first cycle and put back normal embryos with a BFN. Went to Dr. Check listened to his thoughts and read his articles on high stim and how it can effect embryo quality and implantation and decided what the heck he may be right. I had success with Cooper on the first low stim cycle (twins) so something was done right, my past 3 doctors dismissed the idea of high stims causing IVF failure and while that may be true for some it was not the case for me. It was not only easier on the pocket book but also easier on my body.
