绝育
明确决定不打算要任何(或更多)孩子的男女可以选择所有避孕方法中最安全的方法，也就是去做绝育手术。这个手术的结果应该看作是最后的选择。有人正在研究可逆的并由此恢复生育的新手术方法。但是时下还至多是前途渺茫。
 

Contraception

Methods of Contraception: Contraceptive Methods for Either Sex

Sterilization
Men and women who have definitely decided that they do not want any (or any more) children may choose the safest contraceptive method of all, sterilization, i.e, an operation that makes them infertile. The result of this operation should be considered final. Doctors are working on new surgical techniques that would allow for a reversal and thus restore fertility, but at present the chances are still slim at best.
