[The practicality of laser-Doppler spectrometry in andrology].

Hereby we inform about the experimental results obtained using the Lazymot apparatus. It was shown that the assay for both the sperm density and the sperm motility rate are most unreliable. Marked differences were shown between the results obtained from the manual counting procedures and those with the Lazymot device. The input of work into using this apparatus shows no correlation to the output of results. Therefore the Lazymot device is not useful for the routine-laboratory diagnostic.
