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 ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American The predictable swimming sperm featured in ...

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 ...

Sperm change how they swim in response to different conditions in the vaginal tract. The ability to adjust to these conditions could be a measure of sperm health. If this is shown in future research, ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. 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 ...
