Not Contraception
Some proponents of NFP differentiate it from other forms of birth control by labeling them artificial birth control. Other NFP literature holds that natural family planning is distinct from contraception. Proponents justify this classification system by saying that NFP has unique characteristics not shared by any other method of birth regulation except for abstinence. Commonly cited traits are that NFP is "open to life," and that NFP alters neither the fertility of the woman nor the fecundity of a particular sex act. That NFP can be used to both avoid or achieve pregnancy may also be cited as a distinguishing characteristic. Additionally, NFP differs greatly from contraception because, according to action theory, NFP does not "break" the sexual act (separating the action from its purposes) in the way contraception does.
