Three distinct somatic bulbocavernosus reflexes were detected which are components of normal ejaculation. BCM contraction can be elicited after stimulating the dorsal penile nerve at the glans and the anterior urethra; these are the flexor responses of the bulbocavernosus reflex. BCM contraction can also be induced on stimulating the perineal nerve, which is the pathway through which the stretch and the tendon organ reflexes are carried to mediate muscle tone. The motor innervation of the BCM for all reflexes is carried through a branch of the perineal nerve. The findings may be relevant to the evaluation of ejaculatory disorders.
