  ABSTRACT: Objectives: To calculate the incidence of ectopic pregnancy in cases with recurrent early pregnancy loss and cases of recurrent implantation failure. Methods and materials: This is a retrospective cohort study. 200 women were recruited from the infertility clinic at shat by maternity university hospital seeking fertility. 100 of them were with history of recurrent implantation failure (RIF) and 100 with history of recurrent pregnancy loss (RPL). Revisiting their hospital files for the history of ectopic pregnancy was done. Results: 8% of cases of RPL had history of ectopic pregnancy while only 6% of cases of RIF had the history. There was no significant difference between the two groups (p = 0.579). There was significantly higher incidence of ectopic pregnancy in both groups if compared with the general population (p = 0.0001 and 0.043) in RPL and RIF consecutively. Conclusions: RPL and RIF may be considered as a risk factor for ectopic pregnancy.
