Differences in the endometrial transcript profile during the receptive period between women who were refractory to implantation and those who achieved pregnancy

Abstract

Repeated implantation failure in some oocyte recipients is associated with an intrinsic defect in the expression of multiple genes in their endometrium. Significantly decreased levels of several transcripts in endometria without manifest abnormalities is demonstrated for the first time and shown to be associated with implantation failure.
