We wanted to know why sperm sizes differ so dramatically when they all have the same task - to fertilize eggs", said lead researcher John Fitzpatrick from Stockholm University, Sweden. John Fitzpatrick and his colleague Stefan Lupold, from the University of Zurich, examined how competition between sperm from different males and the size of the female reproductive tract influence the evolution of sperm in mammalian species.

Why mice have longer sperm than elephants : The Tribune India

A fruit fly produces the longest sperm known to science. Why do tiny animals make big swimmers, but large animals make small ones? There are competing ideas about why sperm size differs among animals. One idea holds that small animals and large animals have wildly different metabolic constraints. Small animals with high metabolisms are better able to produce new sperm cells than large animals that form new cells more slowly. The other idea has more to do with the female than the male. If a male wants a shot at impregnating a big female, he has to produce as many swimmers as possible.
