This project examines, in collaboration with patient groups, the rise and fall of Primodos and other hormone pregnancy tests (HPTs).
Today it may be difficult to believe that doctors ever prescribed pills as pregnancy tests. However, between the 1950s and 1980s, millions of women worldwide were given HPTs: diagnostic drugs that ruled out gestation by inducing menstrual-like bleeding (a ‘negative’ result; no bleeding implied pregnancy). HPTs were first marketed by the West German pharmaceutical company Schering AG (now Bayer) in 1950. Compositionally similar to oral contraceptives, they prefigured ‘the pill’ by about a decade.
