title: Pattern of testicular biopies as seen in a tertiary institution in nnewi, southeast Nigeria.
abstract: BACKGROUND
  Testicular biopsy is an acknowledged method of examination of the testes for diagnostic and therapeutic purposes. We describe the pattern of testicular histologies in our environment.
  
  
  METHODS
  We carried out a retrospective review of testicular histology results from the Pathology Department of Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, over a 5-year period, January 2008 to December 2012.
  
  
  RESULTS
  During the period, 285 testicular histologies were reported. Eighty-one (28.4%) specimens were pathological specimens, while 204 (71.6%) were nonpathological specimens. Thirty-seven (13.0%) of the histology reports were for diagnostic purpose while 248 (87.0%) were for therapeutic purpose. Based on the results, indications could also be categorized into three, benign testicular pathology, malignant testicular pathology, and testicular biopsy for male factor infertility. Thirty-seven cases (13.0%) were due to male factor infertility with complete spermatogenic arrest as the most common histological finding in 21 (56.8%) of the cases. Malignant testicular diseases accounted for 16 (5.6%) of the indications for testicular biopsies. Benign testicular diseases accounted for 28 (9.8%) of the indications for testicular biopsies. Hemorrhagic infarction from testicular torsion represented the commonest histology in 12 (42.9%) cases, followed by inflammations of the testes.
  
  
  CONCLUSIONS
  Indications for testicular biopsy can be diagnostic and therapeutic. They can also be categorized into benign testicular diseases, malignant testicular diseases, and male infertility. Investigation for male factor infertility was the only diagnostic indication for testicular biopsy. The high incidence of locally and metastatic prostate cancer in males explains why therapeutic removal of the testis is common.
