For example, if the nuclei of the spherical spermatids occupied 10% of the tissue, one would expect these nuclei to be ‘hit’ 10% of the time. With these data, the total volume of the nuclei of each type of germ cell can be determined as the product of its volume density and the total testicular parenchymal volume. By dividing the total volume of these nuclei by the volume of a single nucleus, an estimate is obtained of the total number of cells of each type. The volume of spherical nuclei is usually determined by entering nuclear diameter into the equation for calculating the volume of a sphere.
This would be analogous to the collection of several successive ejaculates from a male after sexual rest. Each ejaculate would reduce the number of residual sperm within the EGR. Ultimately, if water continued to be drawn from a reservoir at a rate exceeding its rate of replenishment, the reservoir would be depleted. At that point, the rate at which additional water could be drawn would be limited by and equal to its rate of replenishment. Similarly, if a male continues to ejaculate at a high frequency, the EGR will ultimately be depleted.
