Abstract

Electromyographic activity was recorded from the bulbospongiosus muscles of intact, copulating male rats to test the hypothesis that urethral stimulation contributes to the ejaculatory reflex. Neither urethral anesthetization with lidocaine nor prevention of emission with guanethidine affected the rhythmic contraction of the bulbospongiosus muscle during the ejaculatory pattern. Urethral stimulation by the ejaculate apparently does not contribute to the regulation of the striated-muscle components of ejaculation-related reflexes in copulating male rats.
