A woman may be able to get forewarning of her partner's propensity to stray by noting the size of his testicles.
Dr Robert Baker of Manchester University, in a study of 80 male student volunteers, has found that those with large testicles were far more likely to be unfaithful to their partners. The average testicle size was 24 cubic centimetres, whilst the largest was 52.
Dr Baker believes that since both the faithful and unfaithful patterns have lasted through evolution, both must be equally 'fit' in passing on the male's genes. The faithful male will impregnate fewer women but is more likely to look after the offspring.
