There is zero scientific evidence supporting the fact that men are somehow genetically more prone to paedophilia then women. However, men do get arrested for it and therefore appear in statistics more. Mainly because there's a huge stigma around reporting when it comes to men/women being used by females. Young boys are supposed to "take it" and chalk it down to experience, and young girls are too terrified/shocked to speak up.
Just read this article and see how many comments from girls and boys (at the time) that were used by either a female relative or a mother.
