Pedophilia was once thought to stem from psychological influences in early life, but now psychologists think it’s a deep-rooted sexual orientation as concrete as heterosexuality or homosexuality, limited almost entirely to men. It becomes clearer during puberty and does not change. It may even be genetic.
The best estimates are that between 1% and 5% of men are pedophiles, meaning that they have a dominant attraction to prepubescent children. Not all pedophiles molest children, and not all child molesters are pedophiles. About half of all molesters are not sexually attracted to their victims.
