Some notable quotes by Margaret Sanger, the founder of Planned Parenthood, include:
- "No woman can call herself free who does not own and control her own body."
- "The most merciful thing that a large family does to one of its infant members is to kill it."
- "Woman must not accept; she must challenge. She must not be awed by that which has been built up around her; she must reverence that woman in her which struggles for expression."
