Morphology
After the motility estimate is complete, allow the slide to cool. Motility will slow or stop and individual sperm cells can be observed.
Switch to the 40x objective and observe individual cells in several fields at 400x.
Note: Mishandling of the sample during preparation could create morphological abnormalities that were not present in the original sample. Cooling or warming the semen too rapidly or physically grinding the cover slip and slide together are examples.
