Birth control, also known as contraception and fertility control, are methods or devices used to prevent pregnancy.
- The only remedy against hunger is reasonable birth control.
- Friedrich Dürrenmatt, Portrait of a Planet (1971)
- ... although every organized patriarchal religion works overtime to contribute its own brand of misogyny to the myth of woman-hate, woman-fear, and woman-evil, the Roman Catholic Church also carries the immense power of very directly affecting women's lives everywhere by its stand against birth control and abortion, and by its use of skillful and wealthy lobbies to prevent legislative change. It is an obscenity -- an all-male hierarchy, celibate or not, that presumes to rule on the lives and bodies of millions of women.
- Robin Morgan, Introduction, Sisterhood Is Powerful, 1970
- Birth control is woman's problem. The quicker she accepts it as hers and hers alone, the quicker will society respect motherhood. The quicker, too, will the world be made a fit place for her children to live.
- Margaret Sanger, Woman and the New Race, Chapter 8, "Birth Control; A Parents' Problem or Woman's?"
- Birth control is the first important step woman must take toward the goal of her freedom. It is the first step she must take to be man’s equal. It is the first step they must both take toward human emancipation.
- Margaret Sanger, "Morality and Birth Control", February-March, 1918, pp. 11,14.
- Birth control must lead ultimately to a cleaner race.

- A revolution in Christian morals.
- The Church Times, December 24, 1930. Quoted in, Theresa Notare, A Revolution in Christian Morals: Lambeth 1930 - Resolution #15. History & Reception, (2008), The Catholic University of America, ProQuest, UMI Dissertations Publishing, p. 463.  Notare explains the significance of this moral revolution: "In their summary of the year 1930, the editors of the Church Times, an Anglo-Catholic publication, noted that Resolution #15 of the Lambeth Conference had caused 'a revolution in Christian morals.' This was not hyperbole. The tradition of Christianity with regard to sexual morality within marriage, was severed for the first time in almost two-thousand years. The most startling aspect of the break is that it was not accomplished by a hostile group, but by a body of Christian bishops who considered themselves to be 'Catholic.' The effect of the pronouncement was nothing short of an ideological shock wave that would penetrate all aspects of modern life. Indeed, the infamous liberal Anglican Churchman, Dean Inge wrote: 'For good or evil' Resolution #15 'will modify profoundly the whole future of mankind.'
