Caption

False-colour scanning electron micrograph of human sperm migrating up the uterus. The sperm (blue) are motile and orientated in the same direction. They travel across a background of uterine mucosa cells (purple, pink). The hair-like surface of the mucosa gives sperm a chemical protection enabling them to reach & fertilize the female egg. The head of the sperm contains human genetic material; its whiplash tail provides movement. Magnification: x4000 at 4x5 inch size x2500 at 6x7cm size.
