The polarity of a potential difference between two spaced apart portions (36, 36) of the body of a woman is measured by a voltage meter (16) is repeatedly measured on each day throughout at least a substantial portion of the days of a menstrual cycle for identifying an ovulation phase within the menstural cycle of a woman. The days in which the measurements indicate at least two readings of opposite polarity are identified as days immediately preceding the time of ovulation of the woman. The required sensitivity for accurate potential measurements is provided by electrodes (24, 24) and circuit (18) and the inconvenience of prior intravaginal electrodes is also overcome by the disclosed electrodes and circuitry. |
