Abstract
The effects of intravenously administered autonomic drugs on the intraluminal pressure and the excretion volume of the seminal vesicles in rats were studied. Both .alpha.1-adrenergic and cholinergic stimulants produced a rapid increase in pressure and fluid excretion. .alpha.1-Adrenergic stimulants elicited a sharp and single increase in pressure, while cholinergic stimulants caused a sharp increase with multiple peaks.
