Abstract:
A 41-year-old Chinese lady had a Gräfenberg ring in utero for 15 years. During that period of time, she had one normal vaginal delivery a year after insertion, followed by an ectopic pregnancy 12 years later. We discuss the possible mechanism of action of the Gräfenberg ring and sequelae of its prolonged presence in the uterus.
