Ectopic pregnancy (EP) is characterized by the implantation and development of an embryo outside of the uterine cavity. The overall rate of EP is 1–2% in the general population, and 2–5% among patients who have utilized assisted reproductive technology.

Anyone capable of conceiving of child-bearing age, who is sexually active or having fertility treatment like IVF, is at risk of ectopic pregnancy. Although the overall mortality has decreased over time, ruptured EP is a leading cause of maternal death during the first trimester with a mortality rate of up to 14%, and also responsible for approximately 5–10% of all pregnancy-related death.

ISUOG has created a bank of resources on ectopic pregnancy, including UOGJournal articles, speaker videos and learning materials.
