In one of the most surprising innovations in medical technology, scientists have created tiny, remote-controlled “sperm-bots” that could one day swim through the human body to deliver drugs, diagnose ...

Sperm cells are known to prefer cooler temperatures. For quite some time, a puzzling question for scientists has been: how do temperature-sensitive swimmers actually operate effectively within the ...

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

Sperm are male reproductive (sex) cells. The word "sperm" can refer to spermatozoon (singular) or spermatozoa (plural). Sperm are tiny cells with an oval-shaped body and a long tail. They measure just ...
