The Sexual Odds combines a humorous account of attempts during the last 2,500 years to produce mainly sons together with an account of how the sex of children is actually settled at conception. Half of the healthy sperms can potentially produce boys and the other half girls, and The Sexual Odds explains for the first time how subtle differences in the swimming prowess and survival of these two types of sperms makes the frequency and timing of intercourse affect the proportions of boys and girls in resulting births.
Potential parents thus better informed should then be able to make up their own minds rationally about the hundreds of methods that have been proposed to change the sexual odds.
