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 ...

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 ...

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 ...

Sperm can modulate their energetics by regulating their flagellar waveform -- how the sperm oscillate their tails -- in order to adapt to varying fluid environments, potentially optimizing their ...

Researchers used machine learning to discover that sperm with a wide head relative to length are more likely to clump together and swim collectively, a rare behavior that sometimes helps them reach an ...

For the first time, researchers have unraveled the structure of a protein that enables sperm to swim. The protein sits in the cell membrane of sperm and helps transport positively charged sodium and ...

Sperm motility refers to the ability of sperm to move or "swim." It is one of the factors tested in a semen analysis. Learn why it's important for fertility. Motility refers to the ability of an ...
