Abstract
A pair of components for an instrument for determining the female fertile period by measuring the viscoelasticity of saliva that includes a pair of strata composed of a rigid material, preferably glass or a polymer, and a surface on each strata, where the surface has a random distribution of peaks and valleys, the average depth from the peaks to the valleys is in the range of from about 10 picometers to about 100 micrometers, and the total area of the valley walls below one half of the average depth is from 35% to 65% of the total area of the surface. Preferably, the average depth of the valleys is in the range of 50 micrometers to 80 micrometers and the total area of the valleys below one half of the average depth is between 45% and 55% of the total area of the surface.
