Swimmers who wore Speedo’s controversial LZR Racer suit at the 2008 Beijing Olympics broke 23 out of the 25 world records broken, proving that being more streamlined has advantages. A new study out of Japan has shown that the same theory applies to sperm.
Spermatozoa must travel through the female reproductive tract to fertilize an egg. With hundreds of millions of them vying for a single egg, having an advantage over the competition is essential. It’s a sperm’s streamlined design that allows for its rapid movement, thereby providing that advantage.
