Castration alters the stimulatory and inhibitory adrenergic influences on isolated rat vas deferens
Responses to adrenoceptor agonistic drugs were examined in two regions of vasa deferentia (epididymal and prostetic) from adult intact and castrated rats. In the prostatic portion the stimulating alpha adrenergic responses following castration were greater than in the intact rats. On the other hand...
