Abstract
The contraceptive effectiveness of any intrauterine device depends largely on its correct position in the uterine cavity. Any method capable of monitoring the position is therefore expected to improve the effectiveness of IUDs. Previous methods used for locating IUDs such as identification of the attached thread and probing of the uterus are largely insufficient. Also the use of the beolocator (Fuchs et al. 1965), hysteroscopy, hysterosalpingography and pelvic X-ray are of limited value because they are inadequate, too time-consuming, invasive or inapplicable in the presence of pregnancy.
