Sperm motion near surfaces plays a key role in fertilization, but a description of how this motion differs from bulk swimming is lacking. Here, Nosrati et al.visualize sperm swimming within 1 μm of a glass surface and describe a ‘slither’ swimming mode which differs from bulk helical swimming, and increases the velocity of human sperm.
