Abstract

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.

DESIGN:

Case series.

SETTING:

University hospital outpatient clinic.

PATIENTS:

Thirty-four consecutive SCI men seeking fertility treatment.

INTERVENTION:

PVS with optimized vibration parameters to induce reflex ejaculation.

MAIN OUTCOME MEASURES:

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.
