1946–1948: Syphilis Experiments in Guatemala

Syphilis experiments in Guatemala were funded by the US Public Health Service (PHS) and the National Institutes of Health (NIH) to the Pan American Sanitary Bureau (later renamed Pan Am Health Org.) The US team of researchers in Guatemala was led by John Charles Cutler, MD of the PHS who had conducted a similar earlier research project at Terre Haute, Indiana prison in 1944, in which the researchers injected inmates with gonorrhea. Cutler and Guatemala records online; includes graphic medical images of the effects of untreated sexually transmitted diseases.
