Evaluations of testicular biopsy by tru-cut in the stallion.

Abstract: 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.

This study examines the use of tru-cut needles for testicular biopsy in stallions, evaluating the adequacy of the biopsy samples, their suitability for histology, and both short and long-term outcomes of the procedure.

Background of the Study

  • Testicular biopsy is an examination often done during andrological tests, but its use in horses is often discouraged due to potential development of testicular sclerosis and atrophy.
  • In human medicine, promising results have been reported with the use of tru-cut needles. Tru-cut needles have an inner recess that cuts and traps the tissue sample, thus enabling the removal of a fragment of tissue with minimal invasiveness.

Aim of the Study

  • The study was designed to investigate the use of tru-cut biopsy needles in stallions, which are otherwise less commonly used in veterinary medicine due to associated risks.
  • The research aimed to determine the appropriateness of the biopsy sample in relation to the size of the needle and the mechanism used to retrieve the sample (either spring-loaded or manual).
  • Additional focus was given to the analysis of the biopsy sample’s suitability for histological examination—a method to study the microscopic structure of tissues.
  • The study also aimed to analyze both short- and long-term outcomes of performing such a procedure on stallions.

Significance of the Study

  • This study is important because it could open up an alternative option for performing biopsies in stallions in a minimally invasive way.
  • Furthermore, by evaluating both the short- and long-term outcomes of the procedure, it can help in understanding the potential impact and viability of using tru-cut needles in vet medicine, especially in treating horses.
