We often imagine sperm as swimmers, tiny cells whipping their tails to power through fluid on a mission toward the egg. However, a new discovery from Monash University researchers reveals a far more ...

TL;DR: College students will compete in a unique sperm race using microfluidic chips that simulate the reproductive system, promoting male health awareness. Backed by $1.5 million in funding, the ...

Human sperm can swim through surprisingly viscous fluids with ease – and they seemingly defy Newton's third law of motion to do so. To figure out how they slither through substances that should, in ...
