Objective: This study sought to evaluate the influence of time (early <90 days and late >90 days) and endometrial injury on pregnancy success.

Methods: This is a retrospective study in which all infertile women who underwent at least one in vitro fertilization cycle at Clinica Gera between 2010 and 2015 were considered for inclusion. We included patients with a normal ovarian reserve and regular menses at intervals of up to 30 days.
