[Corticosteroid response and indolamine content of the mouse brain under the action of a pheromone, disrupting spermatogenesis]

The volatile components of adult male urine from laboratory mice of CBA/LacSto strain inhibited spermatogenesis in CBAB6F1 30-day old mice. There were no significant responses in hypothalamic and olfactory bulb indolamine systems, neither in the blood corticosterone level of the mice during experimental treatment. A prolactin mechanism of the pheromone inhibition of testicular function is suggested.
