Abstract
Objectives To present two cases in which foreign bodies in the uterine cavity had a contraceptive effect for the duration of their presence in utero.
Case One case of endometrial osseous metaplasia and another case with unabsorbed suture material after a caesarean section resulted in foreign bodies acting like an intrauterine contraceptive. Ultrasound was used to diagnose the conditions, and hysteroscopy to remove the foreign bodies.
Conclusion Foreign intrauterine bodies should be considered in cases of infertility.
