Treating Erectile Dysfunction Post-Prostate Cancer Therapy Requires Personalization

Erectile dysfunction (ED) is a frequent complication for patients with prostate cancer. During a presentation on “Men’s Health” at the 2026 Annual APP Symposium, hosted in Nashville, TN, Dan Silver, PA-C, an advanced practice provider specializing in ED, low testosterone, and Peyronie’s Disease, at Arizona Urology Specialists, discussed the diverse etiologies of treatment-induced ED and the importance of implementing early, individualized therapeutic regimens.

The onset and duration of ED often depend on the specific treatment modality utilized. Silver observed that while nerve-sparing prostatectomies are common, the procedure can stun the nerves, with some patients requiring up to 2 years to regain function. In contrast, radiation may lead to a more gradual development of ED over time. For those on androgen deprivation therapy (ADT), the profound reduction in testosterone serves as the primary driver of dysfunction. Regardless of the underlying cause, Silver advocated for early clinical engagement to optimize recovery, stating, “The more that we do up front, the better off people are going to be.”

Pharmacological and mechanical interventions form the cornerstone of Silver’s management strategy. While daily tadalafil is a standard starting point post-prostatectomy, its efficacy can be limited, particularly for patients on ADT whose testosterone levels are suppressed. In cases where oral medications fail, Silver transitions patients to vacuum pumps or injection therapy. Emphasizing a patient-centered approach, he noted that while the general treatment framework is similar across various oncology settings, interventions must be tailored to the individual's history and specific clinical needs to ensure the best possible recovery of sexual function.

Transcript:

If someone's on androgen deprivation therapy, it drops their testosterone. That can cause erectile dysfunction. Obviously, prostatectomy [too]. Even though a lot of them are nerve-sparing now, they still stun the nerves, and they come back with erectile dysfunction, which could take up to 2 years to get their erections back. Then, with radiation, it's not as quick, but it could be more over time that they develop erectile dysfunction. The more that we do up front, the better off people are going to be.

If someone's on androgen deprivation therapy, a lot of times the pills don't work. I'll try them, but a lot of times they don't work. I will go into either a vacuum pump or injection therapy with prostatectomy. I'll always start them on daily [tadalafil (Cialis)]. It may work, it may not, but again, we go to vacuum pumps, we go to injections. It's basically the same treatment regimen for all types of cancer. And I'm very individualized with the patients on what I do with them, depending on their past history and everything else.
