Measurement modes

MetroSperm not only measures sperm concentration of a sample, but also performs the necessary calculations to compute the results which the user actually needs.

The two measurement modes currently implemented address the following use cases:

Check concentration

In this measurement mode, MetroSperm will display the measured concentration expressed in terms of millions of sperm cells per insemination dose volume.
It is also possible to consider a given percentage of abnormal sperm cells, that might have been estimated microscopically, such that the displayed result is given in terms of viable sperm cells.

These are the parameters that can be adjusted in this measurement mode:

Volume of an insemination dose.
Percentage of abnormal sperm cells.

Note that setting the volume of an insemination dose to 1ml will display results in terms of millions of viable sperm cells per millilitre.

Prepare insemination doses

This measurement mode is specifically tailored for the task of finding out how many insemination doses can be obtained from a given raw ejaculate.

These are the parameters that can be adjusted in this measurement mode:

Volume of the ejaculate.
Number of viable sperm cells per insemination dose.
Volume of an insemination dose.
Percentage of abnormal sperm cells.

Results shown are:

Number of insemination doses which can be obtained.
Volume of semen extender that has to be added to the ejaculate to obtain said number of insemination doses.
