“Today I begin a new chapter filled with personal hope and hope for others who have suffered genital injuries, particularly for our service members who put their lives on the line and suffer serious damage as a result,” the 64-year-old from Halifax, Massachusetts said in a statement.

He underwent the 15-hour, groundbreaking procedure at Massachusetts General Hospital last week, which involved a transplanted organ from a deceased donor.

Dr. Mallika Marshall of WBZ-TV News reported that Manning’s doctors are hopeful normal urination and sexual function will be possible. But, as with any transplant, there is a possibility of rejection.

“There are different tissues involved,” said Dr. Curtis Cetrulo at a news conference. “Different lymphatic tissues so we’ll just have to take it day by day and see how we go.”
