Persistent sexual arousal disorder (PGAD), a summary of causes and treatments

Persistent sexual arousal disorder (PGAD) causes and treatment explained

If you’re reading this article because you’re searching for PGAD, chances are you’re thinking to yourself.
“Does this mean I have a strong sex drive?”
“Am I weird?”
“Why do I get these feelings when there’s no stimulation?”

First, let’s be clear.
PGAD is not hypersexuality.
It’s not sex addiction.
It’s not a matter of will.

The nature of this disorder is an overexcited state of the nervous systemof the nervous system.

What is PGAD?

PGAD stands for Persistent Genital Arousal Disorder, which translates to “persistent sexual arousal disorder” in our language. The concept was first reported to the scientific community by Dr. Sandra R. Leiblum in 2001.Initially misunderstood as a sexual problem, the view that it is a disorder related to sensory nervous system abnormalities is now gaining momentum.

Key features of PGAD

  • I’m experiencing sexual arousal when I don’t want to.
  • It rises on its own without any external stimulus.
  • It is not fully resolved by orgasm.
  • The more it repeats, the greater the anxiety and pain.

    Most importantly, it has nothing to do with desire. It’s the disconnect between what the head doesn’t want and what the body responds to – that’s what makes it hardest for patients.

Why is PGAD a ‘pain’ and not a ‘pleasure’?

On the surface, the word arousal creates misunderstandings. But in clinical practice, it’s anything but.

Uncontrollable sensations

The arousal comes without warning – it can happen in a meeting, while driving, or while eating with family. This causes the patient to be on edge all the time.

Unexpected situations create anxiety

The repetition of “what if it comes again?” triggers the sympathetic nervous system, which in turn makes the nerves more sensitive. This creates a vicious cycle.

Leading Cause of PGAD: Nerve Irritability

Recent research describes PGAD as a state of overexcitation of sensory nerves.

1. pudendal nerve overactivity
This is the main peripheral nerve responsible for genital sensation. Compression, inflammation, or muscle tension can cause increased sensitivity.
2. Chronic contraction of the pelvic floor muscles
When the pelvic floor muscles are constantly tense, they compress the nerve and amplify sensation.
3. sacral nerve root lesions
An association with Tarlov cysts has been reported.
4. Lumbar disc problems
If the L4-S1 disc irritates the sacral nerve roots, it can lead to genital paresthesias.
5. Neurotransmitter changes
Cases have been reported, especially after discontinuing SSRIs.
All of these causes have one thing in common. It’s that the nerves are overactive.

Why is the L4-S3 region of the spine important?

While it may seem like a genital problem, it may actually start in the spinal nerve roots. The pudendal nerve originates from the L4-S3 nerve root, which means that stimulation in the lumbar or sacral spine can lead to peripheral paresthesias.

If this stimulation is repeated, the nerve learns to respond loudly to small signals. This is called central sensitization, and when it reaches this stage, sensation can occur even in the absence of stimulation.

Dr. Sang-Cheol Hwang discusses the Chinese medicine perspective on persistent sexual arousal disorder (PGAD)

Chinese Medicine Perspective: Autonomic and Hypochondriac Imbalance

Chinese medicine interprets this as follows

  • Heat Rise in Harcho
  • Impaired blood circulation
  • Ganul
  • Autonomic imbalance

    When the sympathetic nerves, especially the sympathetic nerves, are constantly overactive, blood flow and muscle tone in the pelvic region changes and sensory amplification occurs. This connects to the concept of central sensitization in modern medicine.

Factors that make symptoms worse

The following factors often worsen symptoms

  • Caffeine intake
  • Sleep deprivation
  • Sitting for long periods of time
  • Exercises that overstrain your core
  • Tight underwear
  • Repetitive stimulus behavior

Some people may engage in repetitive masturbation behaviors, especially if they want to get rid of symptoms quickly. While this is understandable, the repetition of stimulation and release can further strengthen the neural circuitry.
The key to treatment is not to eliminate stimulation, but to reduce neural arousal

Is it treatable?

Cure is a word that should be used with caution, but with the right approach, you can expect to see significant improvement.

Keys to care access

  • Control neural arousal
  • Pelvic floor muscle relaxation
  • Autonomic Stabilization
  • Reduced brain irritability

How to treat in practice

  • Neuromodulatory medications
  • Pelvic floor physical therapy
  • Nerve blocks
  • TMS
  • Acupuncture and Autonomic Regulation Therapy

The key is to get the brain and nerves to recognize that it’s safe.

PGAD is not a shameful condition; it’s not a sexual problem; it’s not a lack of willpower; it’s an overexcitable state of the nervous system.There is an explanation, and there is an approach. Rather than searching on your own and increasing your anxiety, get an accurate assessment.You’re not weird, your pain is real, and help is available.
