Abstract
Twenty-four patients with varicocele and 26 normal men were analysed according to the seminal ejaculate and testicular biopsy. Patients were divided into two groups based on the criteria of sperm normality and abnormality, respectively. Hypospermatogenesis with both normal and abnormal seminal fluid occurred in the varicocele patients, but no statistical differences could be established when compared with each other. We concluded that testicular biopsy is not useful in the evaluation of patients with varicocele.
