In 1970, Shulamith Firestone, a self-described radical feminist and writer, published The Dialectic of Sex: The Case for Feminist Revolution, hereafter The Dialectic of Sex. In the book, she argues for the replacement of natural reproduction with artificial reproduction in order to provide women liberation from their reproductive biology. Firestone envisions a day when scientific technology will enable children to be conceived and grown completely outside of a woman’s uterus, what scientists call ectogenesis. At the time of publication, the technology to enable ectogenesis did not exist, although forms of assisted reproduction, such as in vitro fertilization and intrauterine insemination, were starting to be developed. The Dialectic of Sex was one of the first feminist publications supporting ectogenesis, and, as of 2025, it continues to stimulate thinking among many researchers and ethicists who study the implications of new reproductive technologies for women.
