Human sperm are able to swim faster and straighter when they are close to a surface by adopting a unique ‘slither’ according to new research. The research team believes this slither may have adapted to the confined space in the reproductive system.

Researchers filmed human sperm swimming within a micron of a glass surface and compared their behaviour to sperm swimming in a bulk solution.
