When a semen sample is analyzed with a seminogram to evaluate the seminal quality of the male, it is possible that we find an absence of spermatozoa when the semen is observed under the microscope. It is possible that, in fact, there are no spermatozoa in the ejaculate or, on the contrary, there are so few that it is difficult to visualize them.
In these cases, it is advisable to concentrate the semen by centrifugation, so that all the spermatozoa collect at the bottom of the tube. Thus, when the sample is viewed under the microscope, it is possible to identify some spermatozoa and diagnose the male with cryptozoospermia and not azoospermia.
