This refers to avoiding pregnancy without using any "artificial" means such as barrier methods, intrauterine devices, hormones or surgery. Methods considered "natural" include early withdrawal, and/or monitoring of the menstrual cycle to avoid having sexual intercourse on the days of maximum fertility. While less reliable than other methods of contraception, natural family planning is more acceptable to some religious, ethnic or cultural groups.
