The Sexual Odds combines a humorous account of attempts during the last 2,500 years to produce mainly sons together with an explanation of how the sex of children is actually settled at conception. Potential parents thus better informed should then be able to arrange their frequency and timing of intercoure to tilt the odds towards sons or daughters as preferred.
