Surgical sterilisation practices significantly increased in contraceptive capacity as the twentieth century unfolded. Despite this prolific uptake, sterilisation is markedly absent from histories of birth control and family planning and instead has remained addressed within histories of eugenics and coercion. The purpose of this article is twofold: firstly, to demonstrate a voluntary, contraceptive history of sterilisation that is distinct from, though connected to, involuntary and eugenic sterilisation; and secondly, to explain the integral role that individual doctors and their private practice played in the rise of contraceptive sterilisation in twentieth-century Australia. Through a combination of archival material and oral history interviews with twentieth-century practitioners of tubal ligation and vasectomy, this article reframes the history of surgical sterilisation, situating it firmly within the history of birth control.
