: control of the number of children born especially by preventing or lessening the frequency of conception :contraception
: contraceptive devices or preparations
Voluntary limiting of human reproduction, using such means as contraception, sexual abstinence, surgical sterilization, and induced abortion. The term was coined in 1914–15 by Margaret Sanger. Medically, birth control is often advised when childbirth might endanger the mothers health or substantial risk exists of bearing a severely disabled child. Socially and economically, limitation of reproduction frequently reflects a desire to maintain or improve family living standards. Most religious leaders now generally agree that some form of fertility regulation is desirable, though the means are strongly debated. See alsofamily planning.
