Repeated implantation failure (RIF): an iatrogenic meaningless definition that generates unnecessary and costly use of add-on procedures

This opinion paper addresses the literature regarding repeated implantation failure (RIF) in IVF embryo transfer programmes. We provide several lines of discussion as to why such diagnosis might be wrong, why it should not be a call for action or a reason to change the course of treatment, and how RIF biases the quality of the publications and leads to the use of unnecessary and costly adjuvant procedures beyond basic IVF. We argue that these costly add-on procedures are being offered to patients in this highly privatized sector to prevent them from quitting the programme and as a by-product to increase the clinic income. The patients, on the other hand, often equate lucrative hi-tech procedures with possible success and request them despite the lack of proof of the efficacy of most of the procedures.
