Erectile dysfunction can often improve with proper treatment. In many cases, yes, erectile dysfunction can be reversed. A study published in the Journal of Sexual Medicine found a remission rate of 29 percent after 5 years. Within one year, about 40 to 50% of men will have returned to their pre-treatment function.
After two years, about 30 to 60% will have returned to the pretreatment function. These rates vary widely depending on the surgeon and the degree of “nerve preservation” a surgeon can perform at the time of surgery. Often, this issue is important for young men who, by age status, are more likely to have intact erectile function than older men; however, for all men who have normal preoperative erectile function regardless of age, preservation of this function is understandably important after the operation.
