What procedure is specifically referred to as vasectomy?

Vasectomy is a surgical procedure specifically designed for male sterilization and contraception. It involves cutting and sealing the vas deferens, the tubes that carry sperm from the testicles to the urethra. This procedure effectively prevents the sperm from mixing with the semen that is released during ejaculation, thus resulting in infertility.

By focusing on the vas deferens, the procedure effectively blocks sperm transport while leaving other aspects of male reproductive function unaffected. This method is considered a highly effective form of permanent birth control and allows individuals to achieve family planning goals without impacting hormonal levels or sexual function.

The other options presented do not accurately describe what a vasectomy entails, as they refer to different parts of the male or female reproductive systems and different types of surgical procedures entirely.
