Abstract:
:An increasing incidence of male infertility has been noted over the past few decades. This adds urgency to the need to develop immunohistochemical markers for better evaluation of testicular biopsies. We provide evidence that a histopathological evaluation performed according to morphological criteria and assisted by immunohistochemical staining on consecutive sections enhances the sensitivity and accuracy of the diagnosis based on testicular biopsies from infertile men.
