We examined the claim that sperm competition is an important selection pressure operating in human populations. [...] Key Method We recruited 222 men and 194 women to complete a survey of their sexual behaviour. Of these, 28% of men and 22% of women reported engaging in extrapair copulations (EPCs). A review of the literature suggests that rates of extrapair paternity are in the region of 2%. These values suggest that the risk of sperm competition in humans is relatively low, in line with comparative studies of…Expand Abstract
