Male mice which were subjected to irradiation of the testes showed an initial perlod of good fertility which persisted for approximately one month after the irradiation. The fertile period was followed by one of sterilty whose duration varied with the radiation dose. During the sterile period spermatogenesis ceased and spermatogonia were scarce or absent. Six to eight weeks after irradlation a period of renewed fertilty began and continued throughout the remainder of the life span. Offspring sired by irradiated male mice during the poststerility period of renewed fertility were bearers of major chromosomal aberrations. Results indicate that after irradiation there is no safe period during which offspring may be sired which are free from aberrations. (C.H.)
