![]() A sperm is a motile sperm if it can swim rapidly forward in a straight line. ![]() ![]() Many sperm have limited motility, and their movement is restricted to the same spot. Wiggling in the same place will not suffice. However, for fertilisation, we need sperm that can move from one place to another with a rapid forward movement, not the ones that are just twitching their tails or moving around in tight circles. Total motility records all the sperm that are moving, be it the ones that move with forwarding progression, one that moves in circles or the ones that are only fluttering their tails. But according to WHO 2010 criteria in a semen analysis test at least 40% of the sperm should be moving in the given sample to be considered as the normal sperm motility and this is referred to as the total motility. It is not necessary for all the sperm to move. For conception to occur, the sperm need to swim forward towards the egg and fertilise it before it disintegrates. Sperm motility refers to the movement of the sperm and plays a major role in achieving pregnancy.
