Surgeons Transplant a Testicle from One Brother to His Twin

December 9, 2019

(New York Times) – 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 transplant surgeon and urology professor at Tufts University School of Medicine in Boston, who flew to Belgrade to help with the procedure.
