Effect of continuous gamma-radiation on the stem and differentiating spermatogonia of the adult rat.

Abstract

Sprague-Dawley rats were irradiated continuously (60Co, gamma) at a dose-rate of either 1 (0.0007 rad/min), 3 or 6 rad/23-h day for monthly intervals of 1 to 6. At one month after irradiation, counts of differentiating spermatogonia (A1 and A4) were reduced to a level that remained essentially unchanged during the succeeding 5 months of irradiation.
