WHAT IS A PENILE SENSOMETER?


: A Modern Diagnostic Method for Penile Sensitivity, Premature Ejaculation, and Erectile Dysfunction Presented by Prof. Dr. Volkan İzol**

One of the most frequently asked questions regarding men’s sexual health today ispenile sensitivityand its effect on premature ejaculation.The penile sensometeris one of the primary tools used in modern diagnostic evaluations of men who experience premature ejaculation, loss of control, dissatisfaction, and a loss of self-confidence.

The Penile Sensometer is a scientific device that objectively measures penile sensory functions. It evaluates the response of the glans and shaft of the penis to stimulation, thereby identifyingthe cause of premature ejaculationand determiningwhether erectile dysfunction is of neurological origin.

In this blog post, I will explain—in an accessible yet scientific manner, followingProf. Dr. Volkan İzol’sapproach—how the penile sensometer works, in which patients it is used, what kind of results it yields, and why it is so important in modern urology.

What Is a Penile Sensometer?

The Penile Sensometer is a neurodiagnostic device that measures sensitivity levels in the skin of the penis. In short:

👉How sensitive the penis is
👉How fast it transmits stimuli to the brain
👉The threshold values of nerve endings

digitizes it scientifically.

Data obtained:

  • Whether premature ejaculation is caused by hypersensitivity,
  • Whether there is excessive sensitivity at the tip of the penis,
  • Whether nerve freezing (cryoablation) treatment is appropriate,
  • Whether erectile dysfunction is related to a problem with nerve transmission

clearly reveals.

Thanks to this test, the treatment process becomes completely personalized.

Why Is the Penis So Sensitive? The Role of the Dorsal Nerve

The most sensitive part of the penis isthe glans (the head of the penis)and the receptors surrounding it. The nerve that carries sensory signals from this area is calledthe dorsal penile nerve.

This nerve:

  • Pressure,
  • Touching,
  • Vibration,
  • Sense of heat and surface texture

It is transported to the brain extremely quickly.

In some men, this nerve is hypersensitive.
In conclusion:

❗ An erection occurs very quickly
❗ The brain receives the “satisfaction point” signal too early
❗ Control over ejaculation is lost
❗ Sexual intercourse ends in a matter of seconds

The Penile Sensometeris used to scientifically measure this hypersensitivity.

For Which Conditions Is a Penile Sensometer Used?

The penile sensometer test has a wide range of applications. The most common uses are:

✔ Premature ejaculation

One of the main causes of premature ejaculation is hypersensitivity. This device accurately measures sensitivity.

✔ Excessive penile sensitivity (hypersensitivity)

If the head of the penis is very sensitive, the test converts this into numerical data.

✔ Erectile dysfunction

Diabetes, vascular diseases, and neuropathies can affect nerve transmission.

✔ Diabetes-related loss of sensation

It provides an evaluation for men experiencing tremors, numbness, or a burning sensation.

✔ Before nerve freezing treatment

It objectively determines whether hypersensitivity is present.

✔ Nerve Control After Sexual Trauma

✔ Nerve assessment following Peyronie’s disease or penile surgery

In modern urology, measuring penile sensitivity has now becomestandardpractice.

How Does the Penile Sensometry Test Work?

To measure penile sensitivity, the device uses three different types of stimulation:

1) Pressure – Touch Threshold Measurement (Monofilament)

Very light, controlled pressure is applied to the head and shaft of the penis. The threshold value is calculated based on the patient’s reports of when they feel the pressure.

2) Measurement of Vibration Sensitivity

The vibration probe is placed against the tip of the penis.
The device records the value the moment the patient first feels the vibration.

Vibration sensitivity provides information about nerve conduction velocity.

3) Measurement of the Electrical Stimulation Threshold

A very low-level electrical signal is applied.
The response threshold of the nerve endings is determined.

The combination of these three data points results ina sensory map.

How Is the Penile Sensometry Test Performed? (Step by Step)

The test takes10–15 minutesin total and is completely painless.

  1. The patient is prepared

Clothing from the waist down is removed, and the test area is sterilized.

  1. The nerve endings on the head of the penis are identified
  2. A pressure test is performed

The lowest pressure felt by the patient is digitized by the device.

  1. A vibration test is performed

The patient's response is recorded the moment they feel the vibration.

  1. An electrical threshold test is performed

The energy used in this test is very low and does not cause pain.

  1. The results are presented in graph form
  • Hypersensitivity
  • Normal sensitivity
  • Reduced sensitivity

The regions are shown using color-coded graphs.

The entire test is comfortable, fast, and reliable.

What Do Penile Sensometer Results Mean?

Penile sensitivity is divided into three main categories:

1) Hypersensitivity (Hyperesthesia)

It is the strongest indicator of premature ejaculation.

  • The pressure threshold is low
  • Nerves transmit signals very quickly
  • The glans is extremely sensitive
  • The ejaculation reflex is triggered prematurely

In this case, the most effective treatment options are:

  • Nerve Freezing (Cryoablation)
  • Penile head augmentation
  • Desensitization therapies

2) Normal Sensitivity

If sensitivity is not the issue, premature ejaculation is caused by other factors.

In this case:

  • Medication
  • Sex therapy
  • Exercises
  • SSRI Supplements

is recommended.

3) Reduced Sensitivity (Hypoesthesia)

Generally:

  • Diabetes
  • Neuropathy
  • Nerve damage
  • Decreased nerve conduction with age

It is seen in situations such as these.

Treatments:

  • PRP – Exosome
  • Nerve-regenerative treatments
  • Blood Sugar Regulation
  • Treatment for neuropathy

It's possible.

Why Is a Penile Sensometer Important in Premature Ejaculation?

In my clinical practice, approximately 60–70% ofmen who experience premature ejaculation have higher-than-normal sensitivity in the glans penis.

The penile sensometer test is vital for determining the appropriate course of treatment for this condition.

The test provides clear answers to the following questions:

  • Is premature ejaculation caused by sensitivity?
  • Should nerve freezing be performed?
  • Is a penile head augmentation appropriate?
  • Will medication be enough?
  • Is combination therapy necessary?

It increases the success rate of treatment

Treatments planned based on the sensitivity map are much more successful.

For this reason, asProf. Dr. Volkan İzol, I strongly recommend this test before beginning treatment for premature ejaculation.

Is a Penile Sensometer Used for Erectile Dysfunction?

Yes.

Diabetes, vascular diseases, or pelvic trauma can cause problems with erections. In these cases, it is necessary to assess nerve function.

Penile Sensometer:

  • Is nerve conduction slow?
  • Is sensitivity low?
  • Is erectile dysfunction caused by a neurological issue?

provides clear answers to questions such as these.

This also serves as a guide in treatment planning.

How Is Treatment Determined Based on Penile Sensometry Results?

Test results determine the treatment methods:

1) If there is hypersensitivity:

  • Nerve freezing
  • Penile head augmentation
  • Desensitizing creams
  • Dapoxetine / SSRI
  • Sex therapy

2) If sensitivity is normal:

  • Behavioral Techniques
  • Medication
  • Psychotherapy

3) If sensitivity is low:

  • PRP
  • Exosome
  • Electrostimulation
  • Neuropathy Treatments

This makes the treatmentpersonalized.

The Relationship Between Penile Sensometry and Nerve Freezing Therapy

Penile sensometryis the most important criterion for nerve-freezing treatment.

Because the nerve-freezing procedure is effective only in men with hypersensitivity.
For this reason:

✔ A sensitivity test must be performed before nerve freezing.

Nerve freezing in men with hypersensitivity confirmed by testing:

  • Extends the duration of ejaculation
  • Balances sensitivity
  • Boosts self-confidence

This approach is standard practice in my clinical practice.

Advantages of the Penile Sensometer

✔ Results in 10 minutes

✔ Painless

✔ Provides scientific data

✔ Personalizes treatment

✔ Distinguishes between the causes of premature ejaculation and ED

✔ Detects nerve damage

✔ Monitors progress after treatment

✔ It has no side effects

In modern urology, starting treatment without first measuring penile sensitivity is now considered an incomplete approach.

Frequently Asked Questions

1) Does the test hurt?

No. It is completely painless.

2) How long does it take to get the results?

As soon as the test is over, they all leave at the same time.

3) Is the cause of premature ejaculation clearly understood?

If it's due to sensitivity, it's immediately obvious.

4) Can a treatment plan be developed right away?

Yes. Planning takes place after the test.

5) Are the results permanent?

Sensitivity is constant; it may need to be checked at regular intervals over time.

Conclusion: Why Is the Penile Sensometer So Important?

The Penile Sensometer is a modern medical diagnostic device that measures penile sensitivity.
The most critical step in treating premature ejaculation isto measure sensitivityand accurately determine the cause.

  • Premature ejaculation
  • Erectile dysfunction
  • Neuropathy
  • Trauma
