Abstract
The fertile period in a female can be detected by monitoring the calcium and magnesium concentrations in unstimulated saliva. In the three to five day period immediately prior to ovulation, the calcium and magnesium concentrations of saliva drop. This concentration monitoring can be done by any conventional means for quantitatively assaying calcium or magnesium, such as by flow through tests, test strips, cards, charts, probes, meters, and the like.
