Dr. John Henry Hagmann -- a retired Army doctor and noted pioneer of emergency medicine -- has been suspended by the Virginia Board of Medicine for allegedly performing unethical experiments upon human subjects.

According to a report issued by the Virginia Board of Medicine, the 59-year-old has been giving trainees drugs and liquor, and ordering his students to perform questionable medical procedures on one another.

Hagmann, who has been instrumental in training thousands of soldiers, as well as medical personnel in the treatment of battlefield wounds, is said to have provided at least 10 students with the drug ketamine, a powerful painkiller used to put patients under during an operations.

Reuters reports Hagmann allegedly instructed his students to insert catheters into the genitals of other trainees, and also exploiting “for personal gain and sexual gratification” two participants who attended a July 2013 course, which took place at his Virginia farm.

Hagmann also stands accused of conducting what are called “shock labs,” a process wherein blood was allegedly withdrawn from students who were then monitored for signs of shock before getting their blood transfused back into them.

As a practitioner of so-called “live-tissue training,” a method that involves that teaching of students by using wounded live animals as patients, Hagmann has been the target of much criticism from animal rights groups.

PETA -- in an effort to expose common training method's used by Haggman’s federally funded company Deployment Medicine International -- has released a graphic hidden camera video showing what happens to live pigs during DMI training exercises.

Regarding accusations of sexual exploitation of his students, Hagmann contends that “absolutely no ‘sexual gratification’ was involved and there is no evidence of such,” and he maintains that “the courses and procedures in question were all reviewed and approved” by officials at the Uniformed Services University of the Health Sciences.

Haggmann's hearing before the medical board is set for June 19.
