Now described as a modern classic of popular science writing, SPERM WARS is a collection of 37 short stories showing people engaged in sexual behaviour ranging from the routine to the exotic. Each story is followed by an explanation of the science behind the actions to show how our everyday behaviour has been shaped by evolution.

New facts of life are revealed: 10 per cent of children are not fathered by their ‘fathers’; less than 1 per cent of a man’s sperm is capable of fertilising anything; the penis is designed to remove sperm from a woman as well as putting sperm in; “smart” cervical mucus encourages some sperm but blocks others; and a woman is more likely to conceive through a casual fling than through sex with her regular partner.

The book describes how evolution has programmed men to compete with each other to try to conquer and monopolise women, while women, without necessarily knowing they are doing so, subtly but effectively go their own cryptic way to seek the best genetic input on offer from potential sexual partners.

SPERM WARS is a revolutionary thesis about sex that can surprise, entertain and even shock.
