Sperm are basically cells with a tail. It can seem surprising that they are able to navigate and swim with purpose. New research has shown that sperm are even able to switch up directions, and alter ...

Even then, it only takes one sperm to fertilise an egg, with only around 200–500 sperm typically surviving the journey to reach it. Added to that, it turns out that a woman's uterus can actually taste ...

In the race to fertilize an egg, bull sperm that swim in groups travel on a more direct path than sperm traveling alone, James R. Riordon reported in “Sperm in groups outswim loners” (SN: 11/5/22, p.

The behavior of sperm cells is due, in part, to the individual DNA make-up of these cells, rather than only to the genetics of males, finds a team of scientists. Its results, which provide a new ...

Even in the best-case scenario, when fertility clinics transfer chromosomally normal embryos into a would-be mother's uterus, ...

A new mathematical model predicts that mammalian sperm cells have two distinct swimming modes. This prediction opens new questions about potential connections between sperm cells’ motor activity and ...

Dark-field microscopy of individual sperm at 200 frames per second in media with varying shear rates (Scale bar is 20 micron) Sperm can modulate their energetics by regulating their flagellar waveform ...
