@kujhawk1978, thanks for this comprehensive and informative reference. I was encouraged to read how men who have undergone radical prostatectomy, radiation therapy, and hormone therapy might see their ED dysfunction rehabilitated (through oral medication) as a consequence of enhanced blood flow. My doc had me try 100 mg of sildenafil, and that worked; so, we'll see.
Working with their physician, my hope is this reference helps others on a similar post-treatment journey back to life as intended.
Peace and good health to you.
