ANTICHRIST (2008) Lars Von Trier

A woman passing through a tough period of her life after having lost her baby, decides to give up hope, but still holds on to her husband. When she imagines that he will also eventually leave her, she castrates and immobilize him, and then, with a pair of rusted scissors, cuts her clitoris in one of the most viciously shocking scenes Von Trier has filmed so far. After this, both man and woman are unabled to procreate, killing our biblical meaning in the world, and nature becomes a monstrosity.
