[Results of cytological and histological studies on the uterine cervix after long-term intake of hormonal contraceptive agents].

Cytologic examinations with 880 women having constantly used oral contraceptives from one to eight years show no agglomeration of epithelial atypias if the primary status was clearly in the negative. Among 669 histologically sure atypias of cervix uteri the part of women using oral contraceptives for at least one year is significantly lower in carcinoma in situ as well as in early invasive carcinoma. The differences in dysplasia are not significant. The results are also discussed with regard to the efficiency of permanent control examinations before and during the use of oral contraceptions. The demand of a further intensification of cytodiagnostic is derived from these examinations.
