Abstract: Motility and sensitivity to acetylcholine, adrenaline and barium choloride were investigated on the isolated vasa deferentia of rats, ranging from 20 to 180 days old. Spontaneous contractions were recognized only in some of the preparations obtained from 30 day-old rats. These spontaneously motile muscles were more sensitive to acetylcholine and adrenaline than none-motile one. The sensitivities of the vas deferens to the drugs examined, did not show any change during the androgen-secreting period. The relationship between the sensitivity of the vas deferens to the drugs and the androgen output during the growing period was not recognized. The vasa deferentia from 30 and 40 days-old rats showed lower sensitivity than those from the other ages.
