The authors describe an experimental technique of endoscopic autotransplantation of the testis. Four trocars are utilized; one is placed at the level of the umbilicus, one in the right flank, another in the left flank, and one in the hypogastrium. Five or six cms of the epigastric vessels are dissected and sectioned. Then the spermatic vessels and released from the inguinal orifice up to their origin and sectioned. The testis is taken to the peritoneal cavity through the skin and the sustenaculum testis is sectioned. Both vascular pedicles are exteriorized through an incision at the level of the inguinal duct. Microvascular anastomosis is performed as in a routine procedure and the vessels are inserted into the abdomen again, the testis is taken to the scrotum and the inguinal duct is closed from inside.
