The widespread use of contraception has led to increased violence and aggression against women, the theologian of the papal household said during a mid-July visit to Sydney.

Dominican Fr Wojciech Giertych, appointed to his position by Pope Benedict XVI in 2005, said that the contraceptive mentality has distorted male sexuality, leading to violence toward women.

"Contraception is not for women, it's for men," Fr Giertych told The Catholic Weekly, newspaper of the Sydney Archdiocese. "It makes men egoists. It makes many of them degenerates and we're seeing the consequences of that."
