Scientists discover the motion of sperm cells using 3-D technology

If nature finds the best way, then move in a spiral pattern to get there the quickest, from the UCLA Newsroom:

The team developed a lensless computational imaging platform that accurately tracked more than 24,000 individual sperm cells in a large volume. This involved observing the individual rotations of each sperm cell, including helical movement patterns, rotation speed, and linear and curved distances traveled.

90% of them move in a right-handed spiral – damn I’m left-handed – and they move fast for microscopic entities, 20-100 micrometers/second.

That’s a big difference in speed…one sperm cell could be 5x faster than his brother.
