To those born after the Cold War era, it's hard to imagine a time when the entire world wasn't aware of the atrocious medical experiments conducted in Germany. When we look back on the medical experiments of World War II, it may be easy to feel like we're reading science fiction. However, the egregious actions committed by military scientists in WWII Germany were very real. Collected together in this list is a full rundown of regime experiments, one terrible procedure after another. It goes without saying that this list is probably very triggering and it certainly isn't for the faint of heart. From seemingly innocuous experiments on eye pigmentation to truly disgusting procedures involving the creation of conjoined twins and the examining of internal organs, all of the worst stuff is on this list.

Despite their monstrous methods, the scientists did provide helpful research in the field of hypothermia. Years after, researchers still debate whether or not there's a moral quandary in using the findings of Third Reich scientists in modern medicine. This list of experiments is a glimpse into a world of true horror. When you're done here, maybe you should go look at some kitten GIFs.

Heinrich Himmler, a leading SS member, ordered Dr. Carl Clauberg to artificially inseminate concentration camp prisoners through various experimental methods. Clauberg artificially inseminated about 300 women at Auschwitz, who were strapped down and verbally tormented throughout the traumatic process. Reportedly, Clauberg told his victims that he had used sperm from animals - not humans - to create monsters. However, the aim was to access information on treating sterility.

The women selected for the experimentation were between the ages of 20 and 40 and still experiencing menses. These tests were conducted in conjunction with the sterilization experiments.

In the autobiography Remember Us, survivor Martin Small recounted an experiment conducted in 1942. Small witnessed an SS Security Officer named Dr. Wichtmann execute an inhumane experiment on a boy of approximately 11 or 12 years old.

The incident took place inside a building behind the officer's residence in occupied Poland. According to Small:

Inside this structure, in a little room, sat a young boy [...] strapped to a chair so he could not move. Above him suspended was a mechanized hammer that every few seconds came down upon his head. The boy had been driven insane by the torture. Over and over and over, this hammer came down upon his head.

Bone Grafting

The savage bone grafting experiments were an attempt to speed up the body's regenerative process. Sections of a healthy patient’s bone would be removed from their shoulders, arms, or hips, then transferred to a mutilated victim.

Occasionally, entire limbs would be harvested from victims before they perished from an Evipan injection.

Called the Dachau hypothermia experiments, the tests were conducted on men in order to simulate the conditions the armies suffered on the Eastern Front. The experiments were divided into two parts: first, to establish how long it would take to lower the body temperature to one's demise, and second, how to best resuscitate a frozen victim.

The test subjects were either placed in an ice bath or stripped naked and strapped to a stretcher before being left outside in the Auschwitz winter. Approximately 200 prisoners were used throughout the experimentation process.
