Erectile Dysfunction After Prostate Cancer Treatment: What Men Should Know
Sexual side effects don’t always get the attention they deserve when men face prostate cancer treatment decisions. At AnCan, we believe men should be as fully informed as possible about these potential consequences and their impact on quality of life. We hope this information encourages men to have these important conversations with their treatment teams before making decisions. – Stuart Jordan
Erectile Dysfunction After Prostate Cancer Treatment: What Men Should Know
Dr. John Mulhall, a leading specialist in male sexual medicine at Memorial Sloan Kettering, warns that men often begin prostate cancer treatment without fully understanding its potential effects on erections, sexual desire, orgasm, and intimacy. His central message: Protecting sexual function should begin before treatment, not after problems develop.
Surgery vs. Radiation: Different Timelines
Even with nerve-sparing surgery, erectile dysfunction frequently occurs immediately. Recovery can take 18–24 months, depending on pretreatment erectile function, the extent of nerve preservation, and surgeon experience.
After radiation, erections may initially remain intact but deteriorate during the second and third years due to progressive blood vessel damage caused by the radiation. Mulhall observes that by approximately three years, erectile dysfunction rates following nerve-sparing surgery and radiation without hormone therapy may become roughly comparable.
The Added Impact of Hormone Therapy
Androgen deprivation therapy (ADT) suppresses testosterone, potentially reducing sexual desire, impairing erections and orgasms, and contributing to deterioration of erectile tissue.
Testosterone may take months or years to recover after ADT ends, and some men never regain their previous levels. Mulhall urges patients to understand ADT’s expected cancer-control benefit and whether a shorter course might be appropriate.
Why Early Rehabilitation Matters
Mulhall warns that prolonged periods without erections may cause irreversible changes in penile tissue, including fibrosis.
His rehabilitation approach aims to maintain regular erections while nerves recover, using medications such as tadalafil (Cialis) or sildenafil (Viagra), or penile injections when pills fail. However, evidence that these approaches restore long-term spontaneous erectile function remains limited.
Other Important Considerations
Recovery depends partly on age, pretreatment erectile function, and conditions such as diabetes, cardiovascular disease, sleep apnea, and low testosterone.
Sexual function involves more than erections. Orgasm may remain possible despite ED, although its intensity or sensation may change. Performance anxiety can complicate recovery, while alternative forms of intimacy can help sustain relationships. Penile implants are an option when other ED treatments fail.
What Men Should Do Before Treatment
Mulhall strongly recommends that men concerned about preserving sexual function consult a sexual medicine specialist before beginning prostate cancer treatment, rather than waiting until problems develop.
Questions to Ask Before Treatment
- Given my health and current erectile function, what can I expect at one, two, and three years?
- With surgery, how much nerve sparing is possible, and what are my surgeon’s outcomes?
- With radiation, what is my risk of delayed ED?
- With ADT, what’s the added cancer-control benefit, and how long could side effects persist?
- What rehabilitation and sexual medicine support is available?
- How might treatment affect sexual desire, orgasm, ejaculation, penile length, and intimacy?
The essential takeaway: Men should understand their potential sexual side effects and have a plan to preserve sexual function before choosing prostate cancer treatment—not afterward.
