Causes of Erectile Dysfunction

Erectile Dysfunction

Erectile dysfunction (ED) is a condition where a man’s ability to maintain and/or even achieve an erection is diminished to some capacity. By 2025, erectile dysfunction is projected to affect 322 million men around the world.[1] For men struggling with ED, this can be very disheartening, causing anxiety or even embarrassment in the bedroom. There can be many causes of ED ranging, from side effects to certain medications to lower testosterone levels as men age. 

Here at The Hamlet Clinic in London, we specialize in giving men their bedroom confidence back. With our Hormone Replacement Therapy, we offer an approach that tackles the problem head on, creating a solution for the man who wants the vitality of his younger days back. If you wish to schedule a consultation or want to speak with one of our expert staff members please call us at 0207-127-4377.

About ED

A man’s intimate functions are as complex as the man himself. Like other systems in the body, the erectile system works best when given a proper, healthy diet and regular exercise. There can be many causes of ED, and knowing which one is afflicting you is necessary when choosing a treatment approach.

Neurologic Causes

Neurologic refers to nerve damage from injuries, surgeries, or diseases. Nerve damage can hurt a man’s ability to gain a consistent and persistent erection. Neurologic causes can be:

  • Diabetes
  • Chronic alcoholism 
  • Spinal or nerve injuries
  • Nerve damage in pelvic region
  • Peyronie’s Disease

Psychological Causes

A man’s physical health is only as strong as his mental health. Common causes of ED stem from anxiety and depression disorders. Men with depression are 39% more likely to experience ED.[2] When a man experiences depression and anxiety, this can result in a lowered libido. If a man’s libido is lowered it can cause his body’s systems to work harder to achieve the same level of vitality and performance. This can be incredibly embarrassing to a man and disappointing to his partner, leading to worry and anxiety about any future sexual encounters he may have. This performance anxiety then creates a spiral of worry that continually lowers his libido, thus crippling his ability to maintain an erection. If this cyclical pattern persists over time, the man may avoid sexual encounters entirely. 

Hormone Imbalances

As men age, their testosterone levels drop considerably compared to their younger selves. This phenomenon can be seen in a stunning statistic: 50% of men at the age of 50 experience ED, 60% of men at 60, 70% of men at 70 and so forth.[3]  So, it is safe to assume that most men as they age will gradually see more and more instances of ED resulting from the lowered levels of testosterone in their body’s system. However, this shouldn’t be seen as an affliction that only affects older men. 49% of men under the age of 40 experienced symptoms of severe ED as opposed to 40% of men over the age of 40.[4] With lower testosterone levels, a man experiences:

  • Higher stress levels
  • Low energy
  • Poor sleep
  • Low libido


Throughout history, impotence has been treated. Back in 2600 B.C., during the Yellow Emperor’s reign in ancient China, they used a potion composed of 22 esoteric ingredients. Next, in 1600 B.C. an ancient Egyptian medical document posited that the cure for impotence was to mix crocodile tears with wood oil and apply it to the penis. In much more recent times, different oral medications have provided avenues of treating ED. However, these medicines only supply the penis with blood flow and do not account for a spontaneous rendezvous where you don’t have time to run off and take a pill. Frankly, they do not address the overarching causes of ED – the hormone imbalance. 

At The Hamlet Clinic, we offer two different approaches that can revitalize your endocrine system and bring you higher lobido, more energy, and better sleep. These are the perfect solutions for men who want to get back to their lives and don’t have time to wait for a pill to kick in. 

Human Growth Hormone (HGH)

As a man ages, his body starts to produce less human growth hormone than when he was younger. Diminished human growth hormone can result in:

  • Thinning hair
  • Difficulty losing weight
  • Poor mood 
  • Lowered libido
  • Decreased muscle mass and bone density
  • Lethargy
  • Memory issues

 But, after a man goes through human growth hormone therapy, his body can feel youthful and reset. He experiences better sleep, higher levels of energy, lower cortisol levels, higher sex drive, and an invigorated libido. HGH therapy is perfect for men who suffer from ED, because it corrects the hormone disparity in the body that is causing the lowered libido and blood flow. 

Testosterone Replacement Therapy (TRT)

Testosterone Replacement Therapy london

Testosterone replacement therapy works to refresh and replenish the body’s natural testosterone supply. After the age of 20, testosterone levels replenish at about 1 per cent per year. Low testosterone can result in poor sleep, weight gain, difficulty focusing, and sexual dysfunction. As men get older, the worse these symptoms get because less and less testosterone is available in their bodies. 

There are many fixes to the symptoms of low testosterone and erectile dysfunction medications, but these do not fix the root of the problem. When a man goes through testosterone replacement therapy, he can experience a full reboot of his endocrine system which then, in turn, goes to work correcting all the symptoms. 


Men who are perfect for hormone replacement therapy are men who:

  • Suffer from erectile dysfunction
  • Have trouble losing weight
  • Have trouble sleeping through the night
  • Are unable to concentrate effectively
  • Have lost muscle and/or bone mass

If you are someone who has struggled with bouts of ED and have tried other treatment methods or “quick fixes” to no avail, please feel free to contact us to set up a private consultation.
