Have you already tried a penis pump (I haven't yet)?

If that works for you, it would be less invasive than surgery. Otherwise, best of luck!

RARP and RT gave me complete ED. After about a year of very effective trimix injections, I ended up getting Peyronie's Disease. After a following year of outercourse, I decided, and my wife agreed, that it was time for an implant. Had a Boston Scientific AMS 700 implanted late last year and it's quite enjoyable.

Recovery wasn't too bad (I'm 63 years old and fairly active). The surgeon did warn me that it was a one way surgery, since your corpus cavernosa are replaced by the inflatable chambers, there will be no chance for 'natural' erections ever again. Even with a precautions, he also stated that there was still a slight chance of infection, which would require treatment and possibly further procedures. My recovery was uneventful.

The implant does not affect my running; however, I did experience a bit of discomfort when riding a regular bike around the block, but no discomfort on my recumbent road bike. In a deflated state, an implant is bulkier(?) than a flacid penis, so pants that fit tight around the crotch may be slightly uncomfortable. Stretchy garments like compression shorts, running tights or cycling shorts fit and feel OK.

6-8 weeks for recovery. I wore sweatpants through most of it.
