Richard Paulson: RIF Is a Statistical Problem, Not an Inherent Problem With Uterine Receptivity

Richard Paulson, Professor of the Keck School of Medicine at the University of Southern California, shared a post on LinkedIn about an editorial he authored, published in FandS Reports.

“The recent life table analysis articles all agree: Recurrent implantation failure is a statistical problem, not an inherent problem with uterine receptivity. We made this observation in 1997 with data from egg donation.

It took nearly 30 years for IVF to advance and to generate sufficient data with euploid embryo transfer to support and strengthen this conclusion.”

Title: What does life-table analysis of sequential euploid blastocyst transfers tell us about recurrent implantation failure–or lack thereof?

Authors: Richard J. Paulson.
