[Epidemiologic study of cervico-vaginal pathology in IUD users]

1800 intrauterine contraceptive device users, during a period of more than thirteen years, and 1800 control non-users were examined clinically, cytologically and histopathologically for cervical pathological lesions. There was an increase, but not statistically significant, in the incidence of metaplasia, dyskariosis or mild dysplasia. There was no difference in neoplastic lesions.
