The 10 Most evil medical experiments in history of the world – #10 will leave you in the biggest shock of your life!

6. Slave Experiments

It should be no surprise that experiments were often conducted on human chattel during America’s shameful slavery history. The man considered the father of modern gynecology, J. Marion Sims, conducted numerous experiments on female slaves between 1845 and 1849. The women, afflicted with vesico-vaginal fistulas, a tear between the vagina and the bladder, suffered greatly from the condition and were incontinent, resulting in societal ostracism.

Because Sims felt the surgery was, “not painful enough to justify the trouble,” as he said in an 1857 lecture, the operations were done without anesthesia. Being slaves, the women had no say as to whether they wanted the procedures or not, and some were subjected to as many as 30 operations. There are many advocates for Dr. Sims, pointing out that the women would have been anxious for any possibility of curing their condition, and that anesthetics were new and unproven at the time. Nevertheless, it is telling that black slaves and not white women, who presumably would have been just as anxious, were the subjects of the experiments.
