One reason why animals produce so much more sperm than eggs<\/a> is that a sperm is vastly smaller than an egg, so males can afford to produce many more. But they don\u2019t do it just because they can. <\/strong><\/p>

Small, mobile sperm are good at seeking out gametes, and large, well-stocked eggs give them something worth seeking out. <\/p>

It\u2019s a fundamental distinction between the sexes and part of the reason why it tends to be males who put the effort into courtship and fighting off rivals. If a female mates with more than one partner, competition continues within her. <\/p>
The more sperm a male produces, the greater the odds that one of them will reach the target first. The competition is fierce. No wonder a single ejaculate from a bull contains 10 billion sperm.<\/p>
And for another sperm fact, did you know male woodmice have remarkably co-operative sperm? By hooking together in trains of hundreds or thousands of cells<\/a>, they are able to swim faster than single sperm. Now that’s teamwork!<\/p>
