The authors presents 2 observations of testicular autotransplantation at 11 and 13 years age; the 2 boys had bilateral cryptorchism. Analysis of the literature allows good conclusions for the liability of this technique with less than 20% of secondary atrophies. Particularly interesting to note 2 successful operation on children 2 years old. The indications are limited, mainly discussed is bilateral abdominal cryptorchism (mostly Prune Belly Syndrome). The autotransplantation is reserved for the normal appearance testicles with good hormonal function. The operation is preferable using inguino-iliac extra-peritoneal pass; that exploration is very important and at last only in 20% of abdominal cryptorchism could autotransplantation be considered. The malignancy transformation risk is poor if break down is done before 10 years old, however a regular and very long follow-up is necessary: Clinic, vascular, biopsies sometimes at a little doubt. Preservation of hormonal function and fertility hope represent the expected advantages; spermatic analysis are still absent because the too recent autotransplantation. As for usual testicular ectopies for sure it would be preferable to do early autotransplantation, just after 2 years of age, if this is possible.
