Answer Details

As shown in the illustration, part II, the vas deferens, can be cut to ensure permanent sterility. This is because the vas deferens is a tube that carries sperm from the testes to the urethra during ejaculation. By cutting the vas deferens, the sperm cannot be released during sexual intercourse, thus resulting in permanent sterility.
