The fields of urology and sexual medicine are going through one of the most exciting changes in their history. For decades, treating men’s health problems mostly meant managing symptoms — replacing a missing hormone here, or prescribing a short-acting pill for erectile dysfunction (ED) there. But medicine is now shifting away from these temporary fixes and toward something far more ambitious: actually repairing and restoring the body’s natural function.

This shift was the central theme at the 31st Annual Scientific Program of the Sexual Medicine Society of North America (SMSNA), held during the American Urological Association (AUA) 2026 meeting in Washington, DC. Experiencing these presentations firsthand while shadowing Professor Mohit Khera gave me a remarkable look into the future of our field. One thing became crystal clear: the choices men make today about popular, unregulated substances like SARMs are directly connected to the high-tech restorative treatments we will be using over the next twenty years.

Part I: The SARMs Dilemma — Big Promises, Hidden Costs

One of the biggest talking points at AUA 2026 was the explosive popularity of Selective Androgen Receptor Modulators (SARMs). These compounds have jumped from obscure laboratory experiments to substances that anyone can buy online without a prescription. Fitness enthusiasts and aging men looking to improve their physique often see SARMs as a kind of modern holy grail — promising the muscle-building, fat-burning benefits of traditional anabolic steroids, but supposedly without the frustrating side effects like prostate enlargement, severe acne, or hair loss.

The idea behind SARMs is something called tissue selectivity. Regular testosterone switches on androgen receptors all over the body, which is why it causes side effects everywhere. SARMs are designed to be smarter — targeting the receptors in muscle and bone while staying mostly “quiet” in sensitive areas like the prostate and skin. And the research presented at the conference showed that these muscle-building benefits are genuinely real and measurable: studies have found that SARMs can increase lean muscle mass and even improve practical things like walking speed in older men.

The Catch: There’s No Such Thing as a Free Lunch

Despite those impressive muscle gains, the expert presentations drove home an uncomfortable truth: SARMs come with a real price tag for your health. Because they’re so easy to buy online without any medical supervision, most users have no idea about the systemic problems these substances can cause. The conference highlighted several key concerns:

• Everyday side effects: Many users report annoying symptoms like persistent headaches and dry mouth.
• Heart health risks: One of the most consistent findings is that SARMs lower your “good” cholesterol (HDL) — the kind that protects your blood vessels. Over time, this could increase the risk of cardiovascular problems.
• Liver stress: At higher doses, SARMs can put strain on the liver, showing up as abnormal liver test results.
• Shutting down your own hormones: This is the big one. Even though SARMs are marketed as a gentler alternative to testosterone, they actually suppress your body’s own natural testosterone production. The more you take, and the longer you take it, the more your own hormone system gets switched off.

Here’s how that last point works: when you take a SARM, your brain senses the extra androgen activity and responds by telling your body to stop making its own testosterone. The signal from the brain to the testes gradually goes quiet, and your natural hormone levels drop. Worryingly, this suppression can last much longer than the time you were actually taking the substance — and the long-term effects on fertility remain largely unknown, because proper human studies simply haven’t been done yet.

Where SARMs Might Actually Help: A Specialized Role in Cancer Care

Interestingly, the real value of SARMs may lie not with the general public, but in very specific medical situations. A good example is a specialized SARM being studied in prostate cancer survivors.

Prostate cancer is normally fueled by male hormones, which means survivors who struggle with muscle wasting and erectile dysfunction usually cannot safely take standard testosterone therapy. In a carefully controlled trial involving men who were well past their prostate surgery with stable, undetectable cancer markers, researchers tested whether this targeted SARM could help. The results revealed both promise and limits: the drug safely built muscle and reduced body fat without reactivating the cancer — a genuinely encouraging safety result. However, it did not improve sexual function, a reminder that erectile problems after prostate surgery have deep, complex causes that one drug alone cannot fix. The researchers concluded that much more data is needed before this could be used in everyday practice.

Part II: What About DHEA and Other Over-the-Counter Options?

During the session, the discussion turned to where common supplements and alternative hormones actually fit into a urologist’s toolkit. A couple of clear conclusions emerged:

• DHEA: This widely available supplement can slightly nudge up testosterone levels in some studies. But over the long term, it doesn’t produce any reliable improvement in physical performance or strength. When experts were asked whether combining DHEA with testosterone therapy helps, the panel was honest: there are no major downsides, but there’s also no solid evidence that it actually works.
• 5-alpha-reductase inhibitors (medications like finasteride or dutasteride, often used for prostate enlargement or hair loss): These don’t raise testosterone, and in some men they can actually worsen symptoms of low testosterone, such as reduced libido and erectile difficulties.

The take-home message from the SMSNA session was clear: while SARMs and over-the-counter options can change the muscle-to-fat ratio, their side effects, unpredictable hormone suppression, and lack of real benefit for sexual function mean they are not ready for everyday use.

Part III: The Next 20 Years of ED Treatment

The highlight of the scientific sessions was a fascinating, forward-looking lecture by Dr. Johanna L. Hannan titled “ED Targets Most Likely to Translate Into Clinical Practice in the Next 20 Years.” Her talk completely reframed how we think about treating erectile dysfunction.

To understand where we’re going, it helps to look at how far we’ve come:

• 1970s: Treatment was purely mechanical — vacuum devices and early, rigid penile implants.
• 1980s: The arrival of penile injections brought localized medication into the picture.
• 1990s: The real revolution — oral pills like Viagra changed everything.
• 2000s: More oral options arrived, and early stem cell research began.
• 2010s: The focus moved to minimally invasive physical therapies like shockwave therapy and platelet-rich plasma (PRP) injections.
• The road to 2040: The focus is now shifting entirely toward gene therapy and true regenerative medicine — fixing the underlying tissue damage rather than just treating the symptom.

This matters because current pills like Viagra and Cialis work by temporarily boosting blood flow — but they need intact nerves and healthy blood vessels to do their job. For men with serious tissue damage from pelvic surgery, advanced diabetes, or natural aging, these pills often simply stop working. That’s the gap the next generation of treatments is designed to fill. Today there are hundreds of clinical trials around the world focused on erectile dysfunction, and a meaningful share of the most cutting-edge ones are devoted to regenerative approaches like stem cells, PRP, and shockwave therapy.

Part IV: Repairing the Body — Nerve Stimulation, Gene Therapy, and Nanotechnology

Dr. Hannan’s lecture spotlighted three specific scientific pathways that could revolutionize practice by directly healing damaged nerves and blood vessels.

1. A Pacemaker for the Nerves

When a man undergoes surgery to remove the prostate for cancer, the delicate nerves responsible for erections — which sit right next to the prostate — are often bruised, stretched, or damaged. This can lead to erectile dysfunction caused by nerve injury.

Researchers have developed an implantable device that acts almost like a pacemaker for these nerves. A soft, flexible electrode is placed gently over the erection nerves during the healing period after surgery, connected to a small generator that can be recharged wirelessly. By delivering gentle electrical stimulation, the device helps protect the nerves from dying off, encourages them to regrow, and supports the healing process. In an early clinical trial following patients for a full year after robotic prostate surgery, the device proved remarkably safe — with no device-related infections and no significant pain — and helped men maintain their erectile function during recovery. A larger US-based study is now underway.

2. The Science of Touch and Sensation

Another fascinating frontier involves understanding how physical touch turns into sexual signals at the cellular level. Recent studies in top journals like Nature 和 Science have mapped out tiny specialized sensors in the genital skin that drive sexual response. When these sensors don’t work properly, the erectile response to physical stimulation drops significantly.

Scientists have also identified specific touch-sensitive channels that appear to be linked to premature ejaculation — when there are too many of them concentrated in certain areas, ejaculation tends to happen faster. Understanding these channels opens the door to precise, localized treatments that could fine-tune sensation without numbing it, offering better control over both erections and ejaculation timing in the future.

3. Rebuilding Healthy Blood Vessels

The final pillar focuses on repairing the blood vessels themselves using a powerful natural signaling protein called SDF-1, which recruits the body’s own repair cells to fix damaged tissue. In laboratory models of nerve-injury-related ED, injecting this protein directly helped preserve erectile function where it would otherwise have been lost.

But nobody wants repeated injections. So researchers have gone a step further, packaging the genetic instructions for this repair protein inside microscopic protective “nanospheres” — advanced nanotechnology that delivers the healing message directly into the cells. When injected, these nanoparticles stay localized exactly where they’re needed, with no unwanted spread to the rest of the body. In diabetic models — a notoriously difficult cause of ED — a single localized treatment produced a dramatic recovery of erectile function, essentially reversing the tissue damage. This is one of the most exciting directions in the entire field.

Part V: Preventative Urology — Extending Both Healthspan and “Sexspan”

The final takeaway from Dr. Hannan’s presentation connected sexual medicine to the bigger picture of healthy aging. The goal of future medicine isn’t simply to make us live longer — it’s to extend our healthspan, the years we spend healthy and free from chronic disease. And alongside it, what we might call our “sexspan” — the years we maintain a healthy, satisfying sexual life.

The “Zombie Cell” Problem

As we age, some of our cells enter a strange state: they stop dividing but refuse to die. Scientists call these “zombie cells,” and they accumulate over time, leaking out a toxic mix of inflammatory chemicals into the surrounding tissue. This slow drip of inflammation acts like a poison throughout the body, driving many age-related diseases — heart disease, diabetes, Alzheimer’s, and more. Importantly for men’s health, this same process directly damages the blood vessels and muscle in the penis, making it a major hidden driver of both prostate enlargement and erectile dysfunction.

Fighting Back Against Cellular Aging

To counter this cellular decay, urologists are looking at a range of strategies:

• Lifestyle first: Structured exercise combined with a healthy diet — think Mediterranean-style eating, rich in olive oil, nuts, and antioxidants — forms the foundation. These choices calm down systemic inflammation and keep blood vessels healthy and flexible.
• New longevity medications: An emerging class of drugs aims to either clear out these “zombie cells” entirely or quiet down the toxic chemicals they release — protecting the delicate nerves and blood vessels that erections depend on.
• Metabolic helpers: The growing use of modern weight and diabetes medications (like the well-known GLP-1 drugs) reflects a major shift toward proactive, preventative care — tackling the root metabolic causes of disease before they damage sexual health.

The Bottom Line: A Clear Vision for the Future

Attending AUA 2026 in Washington, DC, while shadowing Professor Khera gave me a clear sense of where men’s health is heading. The message for the next generation of doctors and patients comes down to three simple principles:

1. Repair, don’t just patch. Move beyond short-term fixes that only mask symptoms, and focus on therapies that actually heal the underlying cause of erectile dysfunction and tissue damage.
2. Deliver treatments precisely. To bring these breakthroughs safely into the clinic, we need smart delivery systems — like the nanoparticles — that act exactly where needed without affecting the rest of the body.
3. Prevent early. True care means combining advanced surgery with proactive prevention — targeting root causes like cellular aging and metabolic health to extend both healthspan and sexspan.

The journey from today’s unregulated SARMs craze to tomorrow’s precise, gene-based tissue repair represents an incredible leap forward. Guided by rigorous science and inspired by visionary leaders in our field, the next twenty years will fundamentally redefine men’s health — turning the hope of true tissue restoration into an everyday reality.
