Erectile Dysfunction Treatment
Find the cause first. Treat the whole picture.

At a glance

Erectile dysfunction (ED) is common and treatable. It is often an early sign of blood vessel, heart, hormone or nerve problems, so care starts with finding the cause: blood pressure, blood sugar, cholesterol, testosterone, medications, sleep and pelvic floor function. FDA-approved medicines such as sildenafil (Viagra) and tadalafil (Cialis) help many men, alongside treatment of what is driving the problem. Dr. Benjamin (Ben) Klyachman, D.O., board-certified in pain medicine and physical medicine and rehabilitation, leads care at Institute of Function in Nassau County, NY, which welcomes patients from across Long Island, New York City and beyond.

Institute of Function opens in Nassau County, NY in early 2027. Prescribing is physician-supervised after assessment and labs and is never guaranteed. Virtual care is available only in New York when appropriate.

Why ED matters

Erections depend on healthy blood vessels, nerves and hormones. ED can appear years before heart disease, so it deserves a medical evaluation, not just a prescription.

How it is evaluated

History and exam, blood pressure, blood sugar (A1c), cholesterol, morning testosterone, a review of medications that can cause ED (some blood pressure medicines and antidepressants, among others), sleep, stress, and pelvic floor or nerve problems.

How we approach it

  • Treat the drivers: blood pressure, blood sugar, weight, sleep, alcohol and smoking, and medication changes with your other doctors.
  • FDA-approved oral medicines (PDE5 inhibitors): sildenafil (Viagra), tadalafil (Cialis), vardenafil and avanafil (Stendra). They are not safe with nitrate heart medicines.
  • Low testosterone is treated when it is confirmed (see Testosterone Replacement Therapy).
  • Pelvic floor rehabilitation when pelvic floor dysfunction contributes.
  • Other FDA-approved options when pills do not work or are not safe, such as alprostadil injections or vacuum devices, with referral to urology for implants or Peyronie's disease.

Newer therapies and current status

Low-intensity shockwave therapy and PRP injections are not FDA-approved for ED, and the evidence is still limited. We explain what is known before any decision.
