A New Era in Premature Ejaculation Diagnosis: The PENMED Device

What is Sensiometer Test (Vibration Perception Test)?

Sensiometer test is a painless and fast measurement method performed with a special device used to evaluate penis sensory thresholds. The basic principle of the test is based on determining the point where the patient detects the vibrational stimuli given to the skin of the penis. Thus, it provides information about the hypersensitivity of the penile nerve endings (hypersensitivity). 

This measurement supports premature ejaculation diagnosis by evaluating penile sensitivity together with ejaculation time and symptom history. According to the findings, premature ejaculation treatment options can be planned individually.

Basic Principle of Sensiometer Test

 The sensiometer device sends vibration warnings of increasing intensity to the skin of the penis. The patient reports the moment he feels the vibration. This point is recorded as the vibration detection threshold. Lower than normal threshold values suggest excessive sensitivity (hypersensitivity) of nerve endings.Although this method uses an objective measuring device, it is a subjective test. Because the results are based on the patient’s response to the moment he noticed the warning. 

Advantages of Sensiometer Test

 • ✅ Non-interventional: Skin integrity is not damaged, no needles or electrodes are used.

 • ✅ Painless and fast: It is completed in minutes, it can be easily applied in a clinical environment.

 • ✅ Performs nerve mapping correctly: Sensitivity distribution can be seen by taking sensory maps of different areas around the penis.

 • ✅ Valuable in treatment follow-up: Local treatments provide the opportunity to objectively monitor changes after desensitizing agents or nerve modulation.

Disadvantages of Sensiometer Test

 • Gives subjective results: The measurement depends on the vibration threshold noticed by the patient.

• Implementer is dependent: Standardized protocol is a must; doing it in experienced hands increases result reliability. 

Sensiometer Usage in Turkey

 This test, in Turkey ,  It was brought to clinical practice for the first time by Dr  Yaşar Başağa. Thanks to the studies focused on early ejaculation and hypersensitivity carried out in our clinic, the first sensiometer data sets in our country were created. These data presented a new perspective on the distinction between premature ejaculation types by revealing the sensory threshold distribution in the Turkish male population. Recently, the findings presented at national and international congresses show the value of the sensiometer test in the recognition of cases of insidious or hidden hypersensitivity.

Result

The Sensiometer test is an important diagnostic tool that supports clinical observation and history in premature ejaculation assessment. When used properly, it both increases diagnostic accuracy and enables objective follow-up of treatment effectiveness.

What is Pen-Med Test (Pelvi-Perineal Neuro-Muscular Evaluation Device)?

 Pen-Med test is an electrophysiological evaluation method that measures the function of the pelvic floor muscles and nerves. This test objectively reveals the underlying neuro-muscular mechanisms, especially premature ejaculation, erection disorder and pelvic floor dysfunctions. Unlike the Sensiometer test, Pen-Med provides fully objective and measurable data. In this respect, it gives the opportunity to directly observe nervous hyperactivity or reflex increases, which are among the causes of premature ejaculation.

Basic Principle of Pen-Med Device

 The Pen-Med device electrically records nerve and muscle responses through electrodes placed in the pelvic-perineal region.

 In this way: 

• Functional condition of the muscles in the pelvic floor (e.g. bulbocavernosis, ischiocavernosis muscles),

 • The integrity of the reflex pathways between the penis and the spinal cord (e.g. Bulbocavernosal Reflex),

 • Neural transmission speed and response time are measured objectively.

 Thanks to these measurements, it is clearly understood whether premature discharge is caused not only by “sensitivity” but also by an increase in neurogenic reflex.

Advantages of Pen-Med Device

 • ✅ Provides objective and numerical data: The device measures nerve and muscle responses at the level of milliseconds.

 • ✅ Evaluates nerve-muscle functions holistically: The transmission pathways, reflex cycles and muscle contractions in the pelvic region are analyzed in detail.

 • ✅ It shows exactly what is happening: Neuro-muscular processes that play a role in premature ejaculation become observable.

 • ✅ Directs the treatment plan: It helps to determine which mechanism is dominant (hypersensitivity, reflex increase, muscle hypertonia). 

Disadvantages of Pen-Med Device 

• Mild discomfort or pain: Minimal discomfort may be felt due to low-intensity electrical warnings given during the test. However, the process is short and tolerable.

Pen-Med Application in Turkey

 Pen-Med device, for the first time in Turkey,  It was brought to the clinic by Dr.Yaşar Başağa. Thanks to this advanced electrophysiological evaluation system, which is currently only available in our clinic, the first and only Pen-Med data set in our country has been created.These data started a new era in the detection of neuro-muscular causes underlying premature ejaculation, significantly increasing diagnostic accuracy. The results obtained in clinical applications provide very valuable information in terms of detailed mapping of penile reflex pathways and objective follow-up after treatment.

Result

 The Pen-Med test is a gold standard, objective diagnostic tool in evaluating the neurological aspect of premature ejaculation and pelvic floor dysfunctions.It provides great convenience in determining cases of insidious nervous hyperactivity, evaluating reflex control and monitoring treatment success.

Sensiometer and Pen-Med Comparison

 These two tests, which are used in the diagnosis of premature ejaculation, are tools that complement each other in different aspects. You can find the main differences in the table below:

 Result:

 • Sensiometer test is a fast and practical first step tool for understanding penis sensitivity.

 • The Pen-Med test, on the other hand, provides an objective reference in understanding the neurological reflex mechanisms underlying premature ejaculation.

 When used together, they provide comprehensive information about the level of both sensory sensitivity and reflex activity.
