Johns Hopkins School of Medicine already has an active hand transplant program. They even have a face transplant program. Now, it seems, they'll have a penis transplant program.

There, so far, have been only two penis transplants documented in medical journals. The first was a failed attempt in China back in 2006. The other was a successful attempt in Africa earlier this year.

The procedure is still considered experimental, but John Hopkins has given permission to doctors to perform 60 transplants. An estimated 1,367 men in the military have suffered wounds to their genitals from 2001 to 2013 in Iraq and Afghanistan. While the program at John Hopkins isn't exclusive to those injured in war, doctors have stated that it is an important population to serve.

Like any other transplant there are certainly risks with the procedure. But the goal is for the transplant to start functioning within just months. Meaning the development of urinary function, sensation and eventually the ability to have sex.

Screening for potential candidates is already underway, and the first transplant for Johns Hopkins is set to take place within the next year.
