Bank courier Thomas Manning from Halifax, Massachusetts endured a 15-hour surgery in order to receive the organ from its deceased donor.
The 64-year-old spoke to The New York Times from the safety of his hospital room, explaining that all he wanted was to resume his normal life.
“I want to go back to being who I was,” he said.
Manning said he had experienced hardly any pain since the operation that took place nearly two weeks ago.
Leader of Manning's surgical team, plastic and reconstructive surgeon Curtis L. Cetrulo said though the results were positive, there was still a great deal they couldn't foresee due to the novelty of the procedure.
"We're cautiously optimistic," he said.
Cetrulo said that Manning should be able to urinate normally over the next few weeks and recover sexual function in the weeks to months to come.
Manning will however be taking anti-rejection drugs for the rest of his life. Cetrulo said that one of these drugs, tacrolimus, may speed nerve regeneration in order to assist in restoring function to the transplant.
Manning's operation is the third penis transplant to have ever been reported. The first was in 2006 in China and the second in South Africa in 2014.
