Are Immotile sperm dead?
As is well known, completely immotile sperm does not mean dead sperm. Successful fertilization were observed after selection of viable sperm from completely immotile sperm before ICSI [8, 9], which suggests that the basis of ICSI requires a live spermatozoon and not one that has to be motile.
What percentage of sperm should be Immotile?
With that being said, it is important to know that not all the sperm need to be motile or be able to move in the right direction. According to the World Health Organisation, as long as at least 40% of sperm, in a given semen analysis, are able to move properly, it is considered as the normal motility of sperm.
