The main benefits of MetroSperm as compared to other methods are the speed by which results are obtained and the comfort and simplicity of its handling.
As a consequence, results are more reliable, than those obtained by methods more prone to human and technical error.
Microscopic sperm counting, as well as counting by means of a conventional photometer, requires to prepare a dilution of the sample and to transfer this to the device to perform an analysis. This demands additional labware (pipettes, diluent, volumetric flasks, cuvettes, microscope, slides, ...) and experienced operators.
With MetroSperm, however, the operator just needs to immerse the probe directly into the ejaculate, press a button and read the result in a matter of seconds.
This innovation has several consequences:
MetroSperm doesn't require the user to perform any computations nor the use of any conversion table, since it displays the final result.
When preparing insemination doses from an ejaculate, for instance, MetroSperm will display:
The MetroSperm probe is waterproof and highly insensitive to vibration, due to its 1mm thick stainless steel enclosure and the electronic and optical components being potted in solid plastic material.
Farms at remote locations often lack a reliable electrical power supply network.
MetroSperm can be operated either with the battery-powered MetroSperm Host or a portable computer,
thus not requiring external power supply during operation.
For easy transport and storage MetroSperm is supplied in a robust polypropylene suitcase.
Unlike conventional photometers, which measure absorbance just once and at a single wavelength, MetroSperm measures absorbance repeatedly and at three different wavelengths (colours).
Averaging the result of several measurements reduces the error due to inhomogeneity of the sample.
Measuring at different wavelengths extends the range of concentrations that can be evaluated: diluted insemination doses as well as concentrated raw ejaculates.
MetroSperm is particularly suited to prepare dilutions by an endpoint approach: just add diluent while stirring and measuring with MetroSperm's probe until the desired concentration is reached.
This approach is useful, if...:
