 All forms of contraception have played a role in voluntary childlessness over time, but the invention of reliable oral contraception contributed profoundly to changes in societal ideas and norms.Voluntary childlessness, resulting from contraception has influenced women's health, laws and policies, interpersonal relationships, feminist issues, and sexual practices among adults and adolescents.The availability of oral contraception during the late 1900s was directly related to the women's rights movement by establishing, for the first time, a mass distribution of a way to control fertility.
