Penile vibratory stimulation in spinal cord injured men: optimized vibration parameters and prognostic factors.
OBJECTIVE
To study the efficacy of penile vibratory stimulation (PVS) with optimized vibration parameters in spinal cord injured (SCI) men and to examine prognostic factors for success.


METHODS
Case series.


METHODS
University hospital outpatient clinic.


METHODS
Thirty-four consecutive SCI men seeking fertility treatment.


METHODS
PVS with optimized vibration parameters to induce reflex ejaculation.


METHODS
Ejaculatory response; semen analysis.


RESULTS
Antegrade ejaculation was seen in 65% of patients. High rates were seen in lesions above T10 (81%) and in presence of hip flexion and bulbocavernosus reflexes (77%). Of men with lesions above T10, those with a penile prosthesis had lower ejaculation rates (40% vs 90%). Average total sperm counts were 968 million, with 26% motility.


CONCLUSIONS
High rates of ejaculation are seen with optimized vibration parameters, especially in men with lesions above T10 and intact lower spinal reflexes. A penile prosthesis may impair success with PVS.
