Sterilization (medicine)
Sterilization (also spelled sterilisation) refers to any of a number of medical techniques that intentionally leave a person unable to reproduce. It is a method of birth control. For other causes of sterility, see infertility.
Sterilization methods include both surgical and non-surgical, and exist for both males and females. Sterilization procedures are intended to be permanent; reversal is generally difficult or impossible.
