Heterotopic pregnancy (simultaneous ectopic and intrauterine pregnancies) occurs in only 1/10, 000 to 30, 000 pregnancies but may be more common among women who have had ovulation induction or used assisted reproductive techniques such as in vitro fertilization and gamete intrafallopian tube transfer (GIFT); in these women, the overall reported ectopic pregnancy rate is 1 to 2% (1).
