Is there something about all male institutions that encourages child abuse?

Here in Pennsylvania, Jerry Sandusky was just convicted of child abuse, among other things. He was a coach for the Penn State University Football team. He used his access to the team to entice young boys to spend time alone with him. He rewarded those boys with football paraphenalia and trips with the team.

I started wondering what relationship football has, if any, to child abuse. Are there more pederasts attracted to the game because it gives them access to boys? Then I wondered what relationship the university has to abuse. There were reports of Sandusky’s actions, but nothing was done to stop him. Was the university reluctant to act because they wanted to avoid the scandal?

Then I started thinking about other all-male institutions. The navy. Prisons. Boarding schools. Is there something about being all-male that attracts people who like boys? Do these institutions have some special responsibility to protect boys? Or is this a kind of secret thing that some people know about, but most people brush under the table, thinking it isn’t very prevalent or significant?
