I am a quadraplgic. I can get an erection but it only lasts a few minutes. Will viagra help me sustain an erection?

User avatar Hi!

These are some of the relevant lines of articles that might interest you.

'For men whose impotence is caused by psychological factors, Viagra (Sildenafil Citrate) has been shown to work in 90% of these cases. For impotence that is traced to a biological cause, Viagra has a 60%-70% rate of effectiveness. This is even true in cases of spinal cord injury, or in men who have had their prostates removed.'
[ ]

"Erectile Dysfunction caused by difficult-to-treat etiologies such as radical prostatectomy, severe diabetes, and spinal cord injury have demonstrated efficacy." ('Sildenafil: a 4-year update in the treatment of 20 million erectile dysfunction patients.' - December 2003, Current Urology Report journal )

"Existing evidence suggests that oral sildenafil is a highly effective and well-tolerated treatment for Erectile Dysfunction associated with SCI." ( 'Efficacy and safety of sildenafil citrate (Viagra) in men with erectile dysfunction and spinal cord injury: a review.' - September 2002, Urology journal)

From these statements we can come to a reasonable conclusion that viagra works for most patients, but there could be individual variation with some who might not find it utterly useful.

Hope this helps.

Warm regards,

- Bill
