The Guatemala Syphilis Experiment was a medical study from 1946 to 1948 which was conducted on Guatemalan soldiers, prisoners, and mentally ill patients to see the progress of syphilis and gonorrhea. They aimed to find out the stages that affected a variety of people. The initial plan was to cure their patients of syphilis, but the end result was switched to a treatment. However, the doctors and medical professionals forcibly inoculated people with STIs to see how the disease would affect the patients. Patients would be in pain, days on end in unsanitary labratories unless they were chosen for the treatment. The victims never gave consent and were not of informed what the experiment consisted of until it was already too late. 

John C. Cutler conducted the experiment with Dr. Mahoney overseeing it. 

The study was exposed in 2010 by Susan Reverby who brought it up to the president's Commision of Bio-Ethics. To this day, there is still no justice for the Guatemalan families that have been affected by the experiment and no reparations have been given.
