[Cytological complications of IUDs (author's transl)].


 A total of 10,742 women, 2858 wearing an IUD and 7884 on oral contraceptives (OCs) or not contracepting, were observed to examine the possible cervical and endometrial cytological complications of IUD wearers. The published literature agrees that all types of IUDs bring about a modification of the maturation index, and particularly of the estrogenic index, which appears to be lower than that of a control group. Infection rate for IUD wearers was 5.49%; most infections were of a bacterial origin. The rate for metaplasia was 27.4%, for dysplasia 0.12% at average age 35. Papillary metaplasia seemed to appear more frequently than squamous endometrial metaplasia. Anomalies in the cellular glands were found in 2.41% of cases. In conclusion, there does not seem to be an increased risk of specific infection in IUD wearers; rate of frequency is about identical to that of a control group.
