Spinal cord injury in males is frequently associated with infertility, due to ejaculatory dysfunction and/or semen properties alterations. Penile vibratory stimulation can be used as a semen collecting method. The aim of this work is to disclose the use of this method in spinal cord injured male patients, evaluate its possible complications and clarify if the ejaculated semen is prone to fertilization. Vibratory stimulation was used in three spinal cord injured patients to collect semen and, after that procedure, the evaluation of sperm parameters was performed. Vibratory stimulation was efficient in all the subjects, in the majority of the sessions. The ejaculates present normal sperm concentration, but variable sperm progressive motility and morphology, when comparing with the standard criteria. Penile vibratory stimulation is an efficient procedure to induce ejaculation in spinal cord injured patients. Despite the considerable variability between the subjects, the ejaculates met the required quality to allow fertilization trough assisted reproductive technologies.
