MONITORING THE STATE OF A MENSTRUAL CYCLE OF A WOMAN

摘要

At least the polarity of a potential difference between two spaced apart portions of the body of a woman is repeatedly measured on each day throughout at least a substantial portion of the days of a menstrual cycle of the woman. The days in which the measurements indicate at least two readings of oppposite polarity are identified as days immediately preceding the time of ovulation of the woman.
