The Tuskegee Syphilis Experiment was conducted to study syphilis progression in African American men without providing them with treatment, leading to ethical concerns and the eventual halt of the study in 1972.
Explanation:
The Tuskegee Syphilis Experiment, conducted by the U.S. Public Health Service from the 1930s to the 1970s, aimed to understand the natural progression of syphilis in African American men. Despite the discovery of effective treatment in the 1940s, participants were denied treatment to observe the disease's progression.
