Welcome, henry5. It seems to tbe the trend, after some recent research studies being released, for docs to be more aggressive in treating ed problems post-prostatectomy. The 'standard' course, for my doc and the others in his practice is to begin ed drugs at a low dosage at catheter removal. I started with 25mg of Viagra along with 2000mg of l-Arginine, until I could get my order for generic viagra from alldaychemist. I am just now beginning to look at herbal alternatives, including horny goat weed. At the 6 weeks mark, he started me on a penis pump, to keep the penis exercised, blood vessels filled and emptied and such. Sometimes I use the bands to hold it in a couple minutes, mostly, I just pump up and release, allowing the drawn in blood to run back out. One of the first signs of recovery is when the veinous valving starts to keep some of the blood in the penis, by the way. Most guys will get a thickening when sitting on the toilet during a bowel movement or when you do a squeeze and milk action on the penis, which is forcing a small amount of blood into the penis, while stretching it. Also, along with frequent exercise with a pump or otherwise, it is usually recommended to frequently stimulate yourself to orgasm (gotta work around the word editor in this software), either by yourself or with a willing partner. This can be done with or without an erection, and helps to stimulate regrowth and healing in the nerve bundles that have been injured, bruised and such during surgery. At the 3 months mark, if no improvement is shown, he starts penile injections, most doc want to start with Caverject, which is usually problematic for most men, and settles on Bimix or Trimix. There's lots of good info here and elsewhere on these, so I won't go into detail now. As AndrewJ and his doc says, use it or lose it, penile atrophy can be a real result of surgery and needs to be addressed aggressively and early. Hope you hang around with us and share your journey with us.
