title: Evidence for contractility of the human seminiferous tubule confirmed by its response to noradrenaline and acetylcholine.
abstract: The experiments reported here demonstrate for the first time that the isolated human seminiferous tubule is capable of undergoing contraction after exposure to noradrenaline and acetylcholine. Isoproterenol produces a relaxation of the seminiferous tubule. It is indicated that there are the adrenergic alpha and beta receptors and muscarinic receptors in the myoid cells of human seminiferous tubules.
