Hi, after doing plenty of research ive found out that parasympaethic nerves cause an erection and sympathetic nerves are responsible for the penis becoming soft and for controlling ejaculation.

If parasympaethic input is weak then ED and PE will most likely prevail as the sympathetic input will be stronger. If parasympathetic input is strong then a better longer lasting erection will prevail. In some cases ED may be caused by weak parasympaethic nerve input and strong sympathetic input.

It seems like a good avenue to explore the option of reducing the sympathetic input which will allow the parasympaethic to dominate and thus maintain an erection, Yohimbine as this effect. I found a study which investigated suppressing sympathetic nerve input and which appears to be a solution to ED. One of those who carried out the study is called Motta and is a highly respected urologist. Details of the study can be found at the following link:

It appears that this approach is a safe and effective approach to helping some ED sufferers and too me it seams a lot less invasive than a penile prosthesis. The study suggests that temporary sympathetic nerve blocks are used first, if these are effective then a total block is used.

I would much rather go down this route than have an implant which is what my urologist is suggesting.

Does anyone have any further knowledge or would like to contribute any comments regarding this?

Thanks
