[Effect of adrenaline on the post-heat damage to the spermatogenic function in rats].

Administration of adrenaline for 5 days did not produce any effect on the mass and histostructure of rat testes. However, adrenaline overtly potentiated an adverse action of high temperature on spermatogenic function of the testicles (immersion of the scrotum into water heated to 41 degrees C for 30 min). That manifested in a further decrease in the testicular mass and an increase in the number of spermatic tubules which had lost two or more generations of germinal cells. It is assumed that the sensitivity of the testes to adrenaline rises under high temperature.
