Thank you for responding to these questions? I was just wondering if you knew anything about egg quality? Other than changing the protocol, what else is there. I used a standard protocol in my first IVF and a Cetrotide protocol for my 2nd IVF. I got much better response, as far as the number of follicles and what fertilized, but the quality still did not seem good. Example - 3 embryos transferred at the 4-cell stage. Do you have any thoughts about embryo quality? Is there anything to help improve it?
