Abstract

Chromosome analysis was made in induced abortions within 12 gestational weeks after the first day of the last menstrual period. There were 22 cases (7.3%) of gross chromosome anomalies in 300 materials. About a half of aberrant embryos were born to mothers who had positive histories of drug treatments or X-irradiation for various reasons.
