To carry out this technique the sperms are incubated in a tube with a liquid viscous proteic.

The method is based in that during the incubation, a number bigger than sperms Y that X will cross the layer of the liquid proteic. After repeating this process, a sample is obtained with a percentage of sperms that contain the chromosome Y or X (depending on the one you select) bigger than in the original sample.
