It has also been proposed bv ''Gallup et al'' (2003) among others that the penis of male ''H.Sapiens'' partially developed its greater size and distinctive shape (prominent coronal ridge) as a mechanism to displace the semen of competitor by 'scooping' the vagina during coitus, and they also conducted a survey which demonstrated that men were more vigorous and aggressive with their coitus thrusts after a period of separation from their partners.

A review on the matter published in the Journal of Epidemiology and Community Health by Bellis ''et al.''(2005) concluded that "For disputed paternity tests median levels of PD across 16 studies is  26.9%. However, being based on cases where PD was already suspected this inevitably overestimates population levels. For studies based on populations chosen for reasons other than disputed paternity median PD is 3.7%. While this is not a measure of population prevalence it does suggest the widely used (but unsubstantiated) figure of 10% PD be an overestimate for most populations.

The authors also remarked that those most at-risk of paternity fraud were men of low socio-economic status, and those most likely to commit it were young women in concurrent sexual relationships, which apparently included "British women with concurrent sexual partners in past 12 months;16–24 years = 15.2%, 25–34 years = 7.6%" (as of 2005,before Tinder, also obviously self reported data) and the authors of this study noted that this was an increasing trend, at least in the United Kingdom.
