A 36-year-old man born without testicles received one transplanted from his identical twin brother in a six-hour operation performed on Tuesday in Belgrade, Serbia, by an international team of surgeons.
The surgery was intended to give the recipient more stable levels of the male hormone testosterone than injections could provide, to make his genitals more natural and more comfortable, and to enable him to father children, said Dr. Dicken Ko, a urologist and transplant surgeon at Tufts University School of Medicine in Boston, who flew to Belgrade to help with the procedure.
The operation was only the third known transplant of this type. ... The surgery was performed at the University Children’s Clinic in Tirsova, a section of Belgrade. The Serbian brothers are doing well, doctors said. By Friday, the recipient already had normal testosterone levels.
