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 ...

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 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 ...

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.

Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children has ...

Scientists have decoded a protein from sea-urchin sperm that's also found in other animals, including humans, raising a new potential avenue for treating male infertility and developing male birth ...
