Abstract

Concepts regarding the evaluation and management of the infertile male have evolved during the past decade primarily because of the development of new methodology. Nevertheless, the causes of male infertility is often obscure, and the clearly defined causes are infrequent or rare. Testicular biopsy findings are basic and very important in evaluating the causes of infertility. The testis biopsy findings of 30 azoospermic patients were evaluated and it was observed in aspect of testicular size and past history. Following results were obtained. 1. Among the 91 patients who underwent semenalysis, 30 cases (33%)were azospermia. 2. In testicular biopsy findings hypospermatogenesis was the most frequent finding and the more severe hypospermatogenesis was the more atrophic the seminiferous tubule is and showed frequent Leydig cell hyperplasia. 3. Testicular biopsy findings revealed no specific correlation between small testis and normal testis patients. 4. In aspect of past history 2 epididymal tubercu1osis patients showed normal biopsy findings which suggest obstruction of sperm route and one cryptorchism and one varicocele patients showed hypospermatogenesis. 5. By testicular biopsy most of the cause of infertility was testicular and 3 cases were posttesticular.
