Abstract
A novel method is provided for precisely predicting and then ascertaining the time of ovulation by monitoring the mouth air of a female, a first peak after menses in the concentration of said volatile sulfur-containing compounds in said mouth air predicting ovulation by about 5 to 7 days, and a second increase thereafter being indicative of ovulation. Alternatively, a method is provided wherein TPTZ is utilized to sense secondary characteristics associated with the production of volatile sulfur compounds for the purpose of providing a simple colorimetric home test for determining the precise time of ovulation.
