[Incidence of abortive ova in abortion material]

The material of 250 legal abortions is investigated histologically. In 47 cases we have found no trophoblastic tissue. Among the other 203 cases we diagnose 50 (24,6 per cent) abortive ova. 40 cases (19,7 per cent) are suspicious of abortive ovum. Only 7 cases (3,4 per cent) show signs of inflammation. Furthermore in 10 cases (4,9 per cent) early disturbances of placentation (maturation) are supposed. According to the statistical results of are supposed our hospital, the frequency of abortive ova among all pregnancies (number of deliveries, spontaneous abortions and legal abortions) is calculated for 14,9%. The real value of spontaneous abortions may be between 15 and 25 per cent.
