A highly effective tail is needed in order for a sperm to be able to swim, and for a baby to be conceived. By using cryo-electron tomography, researchers at the University of Gothenburg – working in partnership with researchers in the USA – have identified a completely new nanostructure inside sperm tails.
Human sperms are incredibly important for our reproduction. It would therefore be easy to assume that we have detailed knowledge of their appearance. However, an international team of researchers has now identified a completely new nanostructure inside sperm tails, thanks to the use of cryo-electron tomography.
