The Science of Family Planning: Mexico’s “Demographic Explosion,” Contraceptive Technologies, and the Power of Expert Knowledge

This dissertation delves into the history of contraception in twentieth-century Mexico by analyzing the technoscientific activities of local professionals who sought to promote fertility control at a time in which the state maintained a pronatalist policy. By examining the roles of doctors, eugenicists, economists, chemists, and demographers between the 1930s and 1970s, this dissertation argues that these experts contributed to the government’s shift in population policy in the 1970s. Drawing on various archival sources, including clinical reports, institutional records, correspondence, and published materials authored by doctors and social scientists, this study demonstrates how local professionals forged alliances with international donors and fostered interdisciplinary collaborations. All these initiatives allowed these experts to smuggle contraceptives, establish family planning clinics, and even conduct human trials with the birth control pill in Mexico. “The Science of Family Planning,” thus, underscores the complex interplay between state policies, expert interventions, and individual agency, contributing to broader discussions on reproductive rights, public health, and governance in Latin America.
