Body nullification is extreme body modification that involves the voluntary removal of body parts. Body nullification is a well documented phenomenon in modern society, aided in popularity (or at least given a higher profile) by the ability to share information via the Internet that might otherwise be kept isolated or private.

Body parts commonly removed by those practicing body nullification include:

• Fingers
• Toes
• Penis (penectomy)
• Testicles (castration)
• Clitoris
• Labia
• Nipples
