PVS requires premedication to prevent autonomic dysreflexia in patients whose level of injury is T6 or rostral. PVS is more effective in patients whose level of injury is rostral vs caudal to T10,  owing to preservation of the ejaculatory reflex arc. It differed from traditional penile vibrators in that it had two vibrating surfaces which could be applied simultaneously to the dorsum and frenulum of the glans penis. In patients with SCI, fertility is often an important topic for counseling. The goal of our studies is to maximize reproductive options in this severely affected population. PVS has been shown to result in higher yields of total motile sperm compared to surgical sperm retrieval. This latter option is typically required when sperm are retrieved surgically from the testis or epididymis, owing to the low numbers of motile sperm obtained with surgical methods. Detailed information about administration of PVS can be found in previous publications. Written by: Scott M.

The level of lesion ranged from C2 to L1 44 complete. Our experience suggested discrepancies between the manufacturers' specifications and the actual vibrator outputs concerning frequencies and peak-to-peak amplitudes. Retrospectively performed determinations revealed that the manufacturers' specifications regarding the frequencies were accurate whereas the peak-to-peak amplitudes were inaccurate. With a frequency of Hz and determined peak-to-peak amplitudes of 1 mm and 2. This indicates that an adequate peak-to-peak amplitude is essential to exceed an 'ejaculatory threshold' in the majority of SCI men. The ejaculation responses obtained by JS first author were reproduced when the PVS was performed by the patient or his partner, indicating that the vibrator output is more important than PVS experience. No major adverse reactions due to autonomic dysreflexia were observed. The lowest level of SCI where antegrade or retrograde ejaculation occurred was T9 and L1, respectively.
Men with spinal cord injury can frequently achieve erection and have sexual intercourse, however the percentage who can successfully ejaculate is very low. Penile vibratory stimulation is an office procedure that is painless and requires no anesthetic or sedation. Electroejaculation is another technique that can be used to stimulate ejaculation in men with spinal cord injury who are not responsive to penile vibratory stimulation. Skip Navigation.

A specially designed mechanical vibrator is placed at the base of the glans penis and it is set a certain frequency and amplitude.
