During World War II, doctors working for the Nazi party conducted experiments of many kinds on imprisoned people, especially religious people, at the concentration camps, which caused people to be mutilated, cause pain, and even leave people permanently disabled. There were 30 different types of experiments the doctors conducted, but a few of them are High altitude freezing, sulfanilamide, twin, poison, and bone, muscle, and joint transplantation.
At Dachau, doctors experimented on prisoners with high altitude tests. These tests were to help find out the best way to save German pilots when forced to eject in high altitudes. During these experiments, the test subject was put in low pressure chambers and exposed them to altitudes as high as 68,000 feet then monitored the subject until it died from altitude sickness.
German pilots had a problem with being ejected into icy waters. Doctors did experiments on prisoners that put them in vats of icy water up to 5 hours at a time in an aviator suit or naked. Once pulled out, the subjects were in pain and foamed at the mouth while doctors took vital readings. After the vitals were read and the body temperatures were below 79.7F, doctors tried to rewarm them by using hot sleeping bags, hot baths, even naked women. 80-100 victims died because of this experiment.

Doctors used people in concentration camps to test the effectiveness of sulfanilamide and other drugs to curb the effects of gas gangrene. Doctors rubbed ground grass and wood shavings into wounds and tied off blood vessels to simulate a war wound. This caused the victim to have severe pains, serious injury, and some even died due to it.
Doctors experimented with over 1,000 pairs of twins to find out how to effectively multiply the German race. In the experiment, chloroform was injected directly into the heart to find the secrets of multiple births. Only 200 pairs of twins survived.
Doctors injected their test subjects with phenol and cyanide to see the effects. Test subjects who didn't died still were killed so autopsies could be performed.
Bone, Muscle, and joint transplantation
Doctors wanted to learn if limbs or joints could be successfully transplanted from one person to another who had lost a limb. In the experiment, limbs, muscle, and nerves were cut off from prisoners to study regeneration of body parts. The victims suffered pain, mutilation, and permanent disabilities.
