[Injuries of the testis in children]

Thirty three blunt testicular injuries have been observed within the frame work of the French Society of Pediatric Surgery. Four histological stages are described. Stage 1: testis contusion: 17 cases. Stage 2: rupture and retraction of the albuginea: 10 cases. Stage 3: complete testis rupture: 4 cases. Stage 4: testis fragmentation: 2 cases. Diagnosis remains clinical in spite of the recent progress of ultrasonography. After surgical treatment results show: 9% castration, 25% testis atrophia, that is to say one testis out of three is lost after traumatism. The hormonal function was not affected. 2 Testis biopsies allowed us to study spermatogenesis. There is no proof of astheno or azo or teratospermia after childhood traumatism. Sterility by autoimmunization has been mentioned only in adults.
