Testicular biopsy is one of the supplementary examinations performed in the course of andrological testing. In veterinary medicine, it is seldom used in low-fertility or sterility testing, or in the investigation of suspected cancer. Biopsies are discouraged in horses in particular, since they may result in testicular sclerosis and atrophy (Galina, 1971; Smith, 1974; Marusi and Corradi, 1989; Varner, 1991; Del Vento et al., 1992; Threlfall and Lopate, 1993; Roser, 2000). In humans (Foresta and Varotto, 1992; Foresta et al., 1992; Kessaris et al., 1995; Harrington et al., 1996) good results are currently being reported with the use of tru-cut needles (needle assemblies with an inner recess that cuts and traps the tissue sample). These can be used to remove a fragment of parenchymal tissue with minimal invasiveness. Our aim was to study the use of this instrument in stallions; to assess the adequacy of the biopsy sample in relation to the size of the needle and sample retrieval mechanism used (either springloaded or manual); and to analyse the suitability for histology of the specimen. We were also interested in the short- and long-term outcomes of the procedure.
