​The 7 Most Disturbing and gruesome Human Experiments in History

Some of the human experiment below are so disturbing and gruesome that even i couldn’t bring myself not to tear up.  Here are the 7 most disturbing and gruesome human experiments in history.

1. Testicular implants

Dr. Leo Stanley, was the chief surgeon at San Quentin Prison for forty years, while working there, he performed a wide variety of unethical experiments on hundreds of San Quentin prisoners.

Many of his experiments involved testicular implants, where he would remove the testicle of dead prisoners and surgically implant them into living prisoners.

In other experiments, he attempted to implant the testicles of rams , goats, and boars into living prisoners.

2. Radioactive Vitamin drinks

Shortly after World War II, many American medical researchers were preoccupied with the idea of radioactivity and chemical warfare.

In an experiment at Vanderbilt University, 829 pregnant women were given “vitamin drinks” they were told would improve the health of their unborn babies. What the women didnt know was that, the drinks contained radioactive iron. Apparently the researchers wanted to study how quickly the radioisotope crossed into the placenta. At least seven of the babies later died from cancers and leukemia, and the women themselves experienced rashes, bruises, anemia, loss of hair and tooth, and cancer.

3. Experiments on Newborns

In the 1960s, researchers at the University of California began an experiment to study changes in blood pressure and blood flow. And They thought the perfect test subjects would be newborns.

In lieu of this, 113 newborns ranging in age from one hour to three days old were used. The experiments involved inserting a catether through the umbilical arteries and into the aorta, and also immersing their feet in ice water for the purpose of testing aortic pressure. In another experiment, up to 50 newborns were individually strapped onto a circumcision board, then tilted so that their blood rushed to their head and their blood pressure could be measured.

4. Hiroshi Ouchi

In 1999, Japanese worker Hiroshi Ouchi received a deadly radiation dose when material he was working with became critical.

He was exposed to so much radiation that even his chromosomes were destroyed. His fellow doctors saw him, but didnt do anything to help him since no matter what they did, he was still going to die anyway. So they decided to keep him alive to observe the effects of radiation on a person’s health.

His skin and muscles slowly began to fall apart and his intestines began to melt. After 10 days, he begged for death, shouting “I can’t take it anymore, I’m not a guinea pig”. His suffering continued for another 3 months.

5. The Ovitz family

The Ovitz family were Transylvanian Jews made up mostly of dwarfs. They also had a financially sound career as a traveling music troupe.

During their tour of Central Europe, the whole family were captured, loaded into a boxcar and sent off to Auschwitz. Where a doctor known as Dr. Mengele on sighting them was heard saying: ‘Now I will have work for the next twenty years; now science will have an interesting subject to consider.’

At Auschwitz, Elizabeth and her family were segregated and subjected to all manner of  experimentation. As Elizabeth would write:

“The most frightful experiments of all were the gynaecological experiments. They tied us to the table. They injected things into our uterus, extracted blood, dug into us, pierced us and removed samples.”

The gynaecological experimentation was so severe that even the doctors assisting the procedures eventually refused to continue out of pity, whilst citing the very real possibility that the family would not be able to survive further invasive procedure. Dr. Mengele relented as he did not want to risk the lives of his favourite lab rats. Instead, he concocted and implemented new sadistic experiments.

“They extracted fluid from our spinal cords. The hair extraction began again and when we were ready to collapse, they began painful tests on the brain, nose, mouth, bone marrow and hand region.”

The family were among the only ones in the world whose torture was premeditated and ‘scientifically’ documented for the sake of future generations.

Dr. Mengele totrturously experimented on the Ovitz family for seven months until they were rescued by soviet troops on january 27, 1945.

He was never captured or tried for his crimes. He died on a beach in Brazil in 1979.

6. Dr. Henry Heiman

In 1895, in a bid to study the agents of gonorrheal, New York City pediatrician Henry Heiman intentionally infected two mentally disabled boys—one four-year-old and one sixteen-year-old—with the bacteria as part of a medical experiment.

A review of the medical literature of the late 19th and early 20th centuries found more than 40 reports of experimental infections with gonorrheal culture, including some where gonorrheal organisms were applied to the eyes of sick children.

7. Electroshock Therapy on Children

In the 1960s, Dr. Lauretta Bender of New York’s Creedmoor Hospital began what she believed to be a revolutionary treatment for children with schizophrenia. Her methods included interviewing and analyzing a sensitive child in front of a large group, then applying a gentle amount of pressure to the child’s head. Supposedly, any child who moved with the pressure was showing early signs of schizophrenia.

By the time her treatments were shut down, she had used electroshock therapy on over 100 children, the youngest of whom was age three.
