Evaluating sperm morphology

To analyze sperm morphology, as part of a basic semen analysis or spermiogram, a small sample taken from the man's total ejaculate is used. This sample must be spread on a slide, to then be fixed and stained. Therefore, this process implies the death of the evaluated sperm.

However, although these sperm can no longer be used, the analysis of this small sample will be representative of the rest of the man's semen sample.
