Uterine natural killer cell progenitor populations predict successful implantation in women with endometriosis‐associated infertility

Abstract

Our study revealed that uterine NK progenitor cell populations are markedly different in patients with endometriosis who proceed to successful or failed embryo implantation and may define a novel predictor of implantation success. Our findings also highlight the fundamental differences inherent in NK cell repertoires between blood and uterine compartments.
