Abstract

Testis biopsy was performed on 78 rats in order to compare needle and surgical biopsies. The rats were autopsied 7, 15, 30, 60, and 90 days after biopsy. Both techniques provided tissue of equally good quality for histopathological examination and led to irreversible hypo-spermatogenesis of the biopsied and the contralateral testes.
