Surgical sterilization is a medical procedure that permanently prevents pregnancy. It involves surgical techniques to block or seal the reproductive pathways, such as the fallopian tubes in females or the vas deferens in males. This method is considered a reliable form of contraception and is often chosen by individuals or couples who do not wish to have children in the future. The procedure can be performed in a hospital or outpatient setting, and it typically requires anesthesia. While surgical sterilization is effective, it is important to note that it is intended to be permanent, and reversing the procedure can be complex and is not always successful.
