What percentage of men regain erectile function after prostatectomy?

Recovery of Erectile Function After Prostatectomy

For many men, prostate cancer surgery brings life-saving benefits—but it often comes with concerns about sexual health. One of the most common questions is how likely it is to regain erectile function after a prostatectomy.

The answer varies, but studies and clinical data suggest that recovery is possible for many. Within the first year after surgery, roughly 40 to 50% of men return to their pre-surgery level of erectile function. By the two-year mark, that number can rise to between 30 and 60%, depending on several factors.

One of the most critical factors is the surgeon’s technique, particularly the extent to which nerves around the prostate can be spared during surgery. The term “nerve-sparing” is key here. When surgeons are able to preserve these delicate nerves, the chances of regaining natural erectile function improve significantly. However, this isn’t always possible, especially if the cancer is aggressive or located close to the nerves.

Other factors also play a role—age, overall health, whether erectile dysfunction existed before surgery, and even psychological well-being can influence recovery. Many men also find support through treatments such as PDE5 inhibitors (like sildenafil), vacuum devices, or penile rehabilitation programs, which some urologists recommend early on to encourage blood flow and nerve healing.

It's important to set realistic expectations and keep the conversation open with your urologist. While recovery isn’t guaranteed, many men do regain function over time—especially with skilled surgical technique and proactive follow-up care. Every case is unique, but progress is often possible with patience and the right support.
