Can a Device Really Help with ED? What to Know About Vertica

Erectile dysfunction (ED) is more common than many men realise. Tablets like Sildenafil (Viagra) or Tadalafil are often the first step in treatment, and for many, they work well. But not everyone wants to take medication, and for some, tablets don’t deliver the results they were hoping for.
