34 20-26 year old women with anovulatory cycles with the Stein syndrome and 5 women with normal menstrual cycles were studied in regard to bioelectric cervical activity by means of a vaginal probe and the micrograph ''Medicore.'' In the control group, an increase of progesterone in the 2nd phase of the cycle led to a decrease in the electromyographic (EMG) amplitude. In the anovulatory cycle, the extended activity of estrogens and minimal amount of progesterone stimulated a high tone of uterine impulses, which was substantiated by a high EMG proved to be effective and useful in the diagnosis of gynecological patients.
