Testicular tumor cells pass through the epididymal ducts.

Abstract

The diagnosis of early testicular cancer is based on the histological evaluation of testicular biopsies. Like the germ cells, the tumor cells find their way along the tubular duct system of the male urogenital tract into the ejaculate. But only very few data have been published on the exfoliation of testicular tumor cells into the ejaculate in men suffering from early testicular cancer. The screening of ejaculate to detect early testicular cancer would appear to be a rather unsuccessful method.
