Endometrial integrin expression in women with recurrent implantation failure after in vitro fertilization and its relationship to pregnancy outcome

RIF, when defined as failure to achieve a clinical pregnancy after the transfer of at least four good-quality embryos in three transfer cycles, is not associated with abnormal endometrial integrin expression. In addition, the expression of integrins α1, α4, and αVβ3 appears to have no prognostic value in subsequent IVF treatment.
