    Author: Al-Rayess MM, Al-Rikabi AC.
    Journal: Saudi Med J; 2000 Jul; 21(7):625-8. PubMed ID: 11500724.
    Abstract:
    OBJECTIVE: To determine the predominant histopathological patterns seen in the testicular biopsies taken during the investigation of male infertility and to compare the obtained histopathological findings with those seen in other similar studies. METHODS: This is a retrospective study performed on 230 testicular biopsies which were examined in the Department of Pathology at King Khalid University Hospital in Riyadh over a period of 10 years. The histopathological findings were grouped into 8 different morphologic categories. We have utilized a classification that is principally morphologic but that uses known or suspected clinical associations in the case of karyotypic abnormalities and excurrent duct obstruction. RESULTS: Of the total of 230 testicular biopsies studied, 72 cases showed normal spermatogenesis, of which 50 cases were suspected to be associated with excurrent duct obstruction. Germinal cell aplasia with and without focal spermatogenesis was found in about 90 cases. Thirty cases showed hypospermatogenesis, 25 cases showed maturation arrest and 12 cases showed end stage tubular sclerosis with interstitial fibrosis. Only one case was noted to show features associated with karyotypic abnormalities. CONCLUSIONS: A higher percentage of germinal cell aplasia was noted in this study when compared with other similar investigations including one previous local study. Possible causes of these discrepancies may be related to several factors including environmental effects. The design of the different studies and the criteria used for patient selection or both could also explain the cause of these observed differences.
