In a method for predicting the optimum time for insemination of a human female, for maximum conception probability, the salivary and vaginal resistance of the subject is monitored. The optimum time is predicted as the day on which a rise in vaginal resistance is observed, when such day is within six days of the day of observation of a peak in the salivary resistance, or on the sixth day when no such rise is observed. When no such rise is observed by the sixth day, a second optimum date for insemination is predicted as the day on which the rise in vaginal resistance is observed.

Method for predicting optimum time for insemination

A method and apparatus for predicting ovulation in a human female subject. The onset of menstruation of the subject is noted. Daily determinations are made of the electrical resistivity of the subject's saliva, beginning not more than five days following beginning of menstruation. The onset of ovulation is determined as a function of a peak resistivity measurement following onset of menstruation, which peak is followed by a nadir and subsequent sharp increase in saliva electrical resistivity measurement. Vaginal resistivity measurements may be made to confirm ovulation. A probe is used for the resistivity measurement. A probe includes a head or body with exposed imbedded electrodes.
