A history of chlamydial infection is a significant risk factor for ectopic pregnancy. Chlamydia can cause scarring and damage to the fallopian tubes, increasing the likelihood of a fertilized egg implanting outside the uterus.

Identifying and understanding these risk factors is essential for appropriate management and prevention strategies.
