However, this view oversimplifies the situation. The process of embryo implantation, which begins about six or seven days after fertilization, involves a complex interaction…

Dr. Geoffrey Sher answered
Implantation dysfunction is often overlooked as a significant reason for IVF failure.

Embryos & Genetic Testing
I read through your website in your opinion of how many embryos to transfer. Would your recommendation change in the case of multiple failed euploid transfers in someone under 35? I have done all of the recommended testing and have… — Tasha T.
Dr. Geoffrey Sher answered
