Abstract
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.
