Full origin of motility →Frequently Asked Questions
What is the difference between motility and mobility?
Motility is the capacity to move spontaneously using one's own energy, which is why it applies to cells, bacteria and organs. Mobility is the more general ability to be moved or to get about, and it does not imply self-generated movement.
What counts as normal sperm motility?
Laboratories typically look for at least 40 per cent of sperm moving at all, and around 30 per cent showing progressive motility — swimming forwards rather than twitching in place. Exact reference values vary between labs and guidelines, so results should be read against the report's own ranges.
