Answer :

Final answer:

The Tuskegee Syphilis Study involved 600 African American men, 399 of whom diagnosed with syphilis. These men were not informed about their disease nor were they treated, even after a cure was discovered. The remaining 201 men served as control subjects.

Explanation:

The question pertains to the historical Tuskegee Syphilis Study conducted in 1932 in Tuskegee, Alabama, by the U.S. Public Health Service. This notorious research involved unethical treatment of 600 African American men who were promised free medical care, meals, and burial insurance to participate in the study.

Out of the 600 men, 399 had been diagnosed with syphilis and used as an experimental group. These men were never informed of their diagnosis, and even after Penicillin was identified as a cure for syphilis in the 1940s, they were not given the treatment. That leaves 201 men who did not have syphilis, who served as the control group in the study.
