title: [Subcutaneous grafts of fresh or cryopreserved testis in castrated rats and mice: comparison of the histologic aspects of the grafts].
abstract: In the castrated rat, only testis taken in one to two week-old donors observed three months after sub-cutaneous isograft contain a well developed interstitial tissue and some seminiferous tubules with germinal cells. On the contrary in castrated mice, testicular grafts taken in adult animals show some Leydig cells and degenerating seminiferous tubules. These grafts permit the restoration of androgenic activity in previously castrated recipients.
