The sexual development and sex life of 12 women with the Küstner-Rokitansky syndrome, in whom the developmental anomaly (vaginal agenesis) was corrected through surgery, were examined through structured interviews and by means of questionnaires. The comparison group was 22 women who had regular menses and a functional sex life. All differences between the groups were statistically nonsignificant. Only in one questionnaire was there a slight trend toward retarded heterosexual development in the patient sample.
