Bilateral testicular biopsy--is it necessary?

ABSTRACT

Bilateral testicular biopsies from 202 infertile males were examined to ascertain the differences in the degree of damage to the germinal epithelium on both sides. Depending on the histologic changes, the biopsies were divided into six groups. A significant difference in the morphology on both sides was seen only in 3% cases. The left and the right testes were equally damaged in cases with similar morphology.
