[Fertility and pregnancy after conization].

Conization is frequently used as a diagnostic and curative method for the prevention of the cervical cancer on women of the fertile age. Conization was performed on 408 women up to 40 years in our Clinics during the years 1967 to 1989. The percentage of attested postoperative pregnancies among these women amounts to 13.51% and declines with age; it is high among women up to 25 years of age (29%) and low (3%) among women between 36 and 40 years. The percentage with premature births before the operation was 15.25%; after the operation the percentage declined to 13.31%. Preventive cerclage was used on one part (8.1%) of the latter percentage and no cerclage on the remaining 5.4%. It is concluded that there is not high danger of premature birth after conization and therefore performance of the operation does not seem to necessitate preventive cerclage.
