Particular aspects of seminiferous tubules at early puberty

In the seminiferous tubules of patients at early puberty we have observed Sertoli cells showing an homogeneous aspect. In the cytoplasm of some of these elements dense bodies, which present a particular structure and shape, have been recognized. As far as the germ cells, we can find spermatogonia, spermatocytes and spermatids at various developmental stages. The presence of intercellular bridges among the germ cells and of binucleated spermatids with only one acrosome is a characteristic and fairly frequent finding in our specimens, obtained from normal patients.
