Sperm motility is an important parameter for achieving pregnancy, because if the sperm do not move correctly, fertilisation of the egg will not occur. For this reason, the World Health Organisation (WHO) establishes that a seminal sample must have at least 40% of spermatozoa moving and 32% of them must do so progressively, that is to say, moving forward.
