[Antimutagenic effect of chemosignals from isolated female house mouse on male germ cells (Mus musculus L)].

The influence of chemosignals from isolated mature females of the CBA line on level of spontaneous and radiation-induced meiotic disturbances in spermatocytes I of males of the same line was studied. Using an ana-telophase method, 24-hour exposure of males to soiled bedding containing isolated females chemosignals was shown to lead to a significantly lower frequency of chromosomal aberrations and other meiotic disturbances in spermatocytes I as compared to males kept on clean bedding. The same effect of female chemosignals was found in the reproductive cells of irradiated males (4 Gr).
