Objectives:
To demonstrate the different techniques used to perform successful penile vibratory stimulation (PVS) to induce ejaculation in men with spinal cord injuries (SCIs).
Design:
A video demonstration of the PVS procedure performed in men with SCIs using the FertiCare 2.0 medical vibrator.
Setting:
Major University Medical Center.
Patients:
Men with SCIs.
Intervention(S):
Spinal cord injury is the leading cause of anejaculation in young men. After SCIs, most of these men will need a method of assisted ejaculation to achieve biological fatherhood. In this study, a newly designed and tested vibrator (FertiCare 2.0) was used to induce ejaculation. The initial assessment of each patient included a standard history, physical examination, level of injury determination using the International Standards for Neurological Classification of Spinal Cord Injury as well as assessment of the hip flexor reflex and the bulbocavernosus reflex. Patients with a level of injury at or rostral to T6 were pretreated with 10-40 mg of sublingual nifedipine to manage autonomic dysreflexia. A single vibrator was applied to the dorsum, or frenulum, of the glans penis. Stimulation is delivered in 2-minute increments to a maximum of 10 minutes per visit. Application of two vibrators or abdominal electrical stimulation concurrently with PVS was used in select patients. Ejaculated semen was collected in a sterile cup and examined after liquefaction. Bladder preparation using sperm wash medium was performed in patients suspected of experiencing retrograde ejaculation.
Main Outcome Measure(S):
Successful ejaculation after performing the PVS procedure in men with SCIs.
Results:
Penile vibratory stimulation was successful in 86% of men whose level of injury was T10 or rostral. The total motile sperm count in antegrade ejaculates produced using PVS was >5 million (lower limit considered for intrauterine insemination) in 71% of ejaculates. No complications because of PVS were observed in 3,700 trials performed by our group and none in the patients presented in this video.
Conclusion(S):
Penile vibratory stimulation is a safe and effective method for the management of ejaculatory dysfunction in men with SCIs. Penile vibratory stimulation can be performed by the male partner after an initial evaluation by a specialized provider, and the ejaculate can be used to perform home insemination.
