How Sex Changed

Joanne Meyerowitz’s How Sex Changed is not simply the story of how an operation was invented. It explains how “sex change” became thinkable, nameable, reportable, treatable, and politically claimable in twentieth-century America. Beginning with European sexology and early medical experiments, Meyerowitz follows knowledge, techniques, migrants, newspapers, and personal accounts across the Atlantic. Sex ceased to function as an unquestioned permanent truth and became an object medicine could alter, law had to adjudicate, and the public continually contested.

The media sensation surrounding Christine Jorgensen’s 1952 return to the United States is the book’s pivotal episode. News reports presented her as a miracle of modern science while creating spectacle through voyeurism, moral judgment, and tests of femininity. Publicity gave many people language for their own experience, but also established a narrow model of successful transition: white, elegant, heterosexualized, and cooperative with medical narratives. Visibility could open a route to life while intensifying scrutiny over who counted as authentically trans.

Meyerowitz insists that trans people were not passive products of medicine. Louise Lawrence built correspondence networks, preserved knowledge, and connected researchers with communities; Reed Erickson used personal resources to support clinics, publications, and organizations. Letters seeking care, mutual-aid networks, and testimony show people learning physicians’ language to obtain treatment while privately revising, refusing, and enlarging it. Modern trans medicine emerged through conflict among patients, activists, doctors, funders, and media—not through expert invention alone.

As clinics formed, gatekeeping through psychiatric diagnosis, eligibility rules, and real-life tests determined access to hormones and surgery. Courts confronted birth certificates, marriage, employment, and legal sex, while gay liberation and trans organizing developed both alliances and contested boundaries. The title thus carries a second meaning: individuals changed their bodies, but society was also forced to change its definition of sex as chromosome, anatomy, psyche, identity, or legal status.

Completed in 2002, the study uses the period term transsexuality and centers medical binary frameworks and highly visible figures; race, class, nonbinary life, and transmasculine experience receive uneven attention. It should be read beside Gill-Peterson’s history of trans children, trans-of-color scholarship, and newer struggles against pathologization. Even so, its archival foundation remains indispensable. Trans history appears neither as linear medical progress nor sudden media invention, but as a political history in which trans people continuously contested control over bodies, knowledge, and legitimate life.
