Sperm washing techniques are gradient, flotation and micro fluidic chip method. The main principle of sperm washing is to collect the best quality sperm in the fastest and most gentle way. The main purpose of this type of sperm selection, no DNA fragmentation, have a nucleus, motile, is to provide a morphologically normal sperm.
