Human Sperm Swim Like 'Playful Otters,' New Study Finds


A new study has revealed that everything we thought we knew about sperm movement was a lie: Those persistent little swimmers don’t wiggle their way towards an egg like a snake, but rather roll around like an otter. That revelation, published Friday in the journal “Science Advances,” came from scientists at the University of Bristol and the National Autonomous University of Mexico, who reconstructed the movement of a sperm tail using three-dimensional microscopy. The researchers’ findings go against the observations of Antonie van Leeuwenhoek, the Dutch scientist often known as the father of microbiology who was the first to document bacteria and red blood cells. Van Leeuwenhoek also just happens to hold the unique distinction of having studied his own sperm under a microscope in 1677, with his erudite ejaculate evaluation published by the Royal Society of London a year later. In reality, sperm wobble through the water in a manner quite unlike an eel, with their tails rotating repeatedly only on one side, like a spinning top.
