A case of testicle replantation.

A case is reported of amputation of the testis, which was reattached to the stump of the severed spermatic cord using a microsurgical technique and local hypothermia. Total ischemia time was 4 hours and 20 minutes, including 3 hours for warm ischemia. Ultrasonography of the replanted testis 6 months postoperatively showed a homogeneous parenchymal echo pattern and color-coded duplex sonography confirmed normal blood flow. Semen analysis and serum testosterone level were normal. A biopsy of the replanted testicle revealed active spermatogenesis and a normal number of Leydig cells.
