The<unk>  were conducted by Dr. John C. Cutler in 1943 and 1944 under Dr. John F. Mahoney, the head of the Venereal Disease Research Laboratory of the US Public Health Service, to determine the effectiveness of treatments for sexually transmitted diseases. The test subjects were<unk> ers at the U.S. Penitentiary in<unk><unk> , Indiana. They were given disclosures and consented to the experiments. A total of 241<unk> ers participated in the study and received $100, a certificate of merit, and a letter of commendation to the parole board at the end of the study. The researchers deposited various strains and concentrations of gonorrhea into the penises of the test subjects. After several months, Mahoney noted that the method of inducing gonorrhea in humans was unreliable and could not provide meaningful tests of prophylactic agents. The<unk><unk>  experiments laid the foundation for and bore many similarities to the Guatemala syphilis experiment, including many of the same researchers, goals, and methods.
