Description:Media can only be downloaded from the desktop version of this website. Share Leave a comment Like salmon traveling upstream to spawn, sperm cells are extremely efficient at swimming against the current, according to research to be published this week. The discovery, to be published in the journal eLife by researchers at MIT and Cambridge University, may help us to understand how some sperm travel such long distances, through difficult terrain, to reach and fertilize an egg. Of the hundreds of millions of sperm cells that begin the journey up the oviducts, only a few hardy travelers will ever reach their destination. Not only do the cells have to swim in the right direction over distances that are around 1, times their own length, but they are exposed to different chemicals and currents along the way.
