Podcast # 339: Ectopic Pregnancy Risk Factors

Author: Jared Scott, MD

Educational Pearls:

  • Data is mixed, but some studies show 1-2% of pregnancies are ectopic.
  • Risk factors for ectopic pregnancies include: pelvic inflammatory disease, prior ectopic pregnancy, prior abdominal surgery, prior abortion, advanced maternal age, IUD, tubal blockage, and smoking (including spouse).
  • Greatest risk factor is a prior ectopic pregnancy, which carries a 17x higher risk.
  • Patients with histories of PID and cigarette smoking present educational opportunities.
