Abnormal sperm. Coloured scanning electron micrograph (SEM) of a sperm cell with an exposed central flagellum at the base of its tail. This deformity can lead to the tail breaking off, rendering the cell immotile. All men have a few deformed sperm in their ejaculate, but an overabundance of them can mean that the man is infertile. Magnification x8000 when printed at 10 centimetres wide.
