According to fine-touch pressure threshold studies conducted on the sensitivity of the penis there are some nineteen zones of sensory tissue on the uncircumcised penis and eight on the circumcised. However, in saying this, there are two regions on the circumcised penis that are very sensitive, which the uncircumcised penis does not have. This is a result of circumcision.

Fine-touch Penis Sensitivity Studies

Studies on fine-touch penis sensitivity revealed that factors such as age, type of underwear worn, and the time that had elapsed since last ejaculating had a bearing on the sensitivity of the penis in both circumcised and uncircumcised men.

It was also interesting to note that the nerve endings in the penis varied in sensitivity level depending on their location. The Glans (head of the penis) had what was referred to as ‘free nerve endings’ that were able to sense ‘deep’ pressure, whereas the band or ridge of the penis head had many more fine-touch receptors that made it more receptive to lighter touch.

The studies concluded that circumcision scar was the most sensitive on the circumcised penis and that the foreskin left on the uncircumcised penis was the most sensitive. Other findings were as follows:

1. Men who wore boxers or briefs had more penis sensitivity rather than those who wore no underwear;

2. Younger men had greater penis sensitivity than older men; and

3. The time that had elapsed between ejaculations did not alter penis sensitivity.

Penis Sensitivity Testing

The official test of penis sensitivity is called a ‘bioesiometry test’. The test uses an electromagnetic vibration to gauge how sensitive the penis is, and how well the nerves function within the penis. If a decrease of sensitivity is recorded then this may indicate nerve damage.

A normal reading in young males should be relatively low, with them being responsive and sensitive to minimal vibration. The older the individual being tested is, then the higher the reading. The reading, however, should not be any higher than 30-40 volts; otherwise this could be an indication of extensive nerve damage.

Another test that is performed to check penis sensitivity is the microfilament test. This involves filaments of different sizes being placed on the Glans, whilst the patient is unable to see, and then testing the reaction to various levels of stimulus.

Penis sensitivity can be tested at home, with a partner, using a simple method. This is as follows:

1. Place an ice-cube and a feather by the side of the bed.

2. Place a blindfold on.

3. Have the partner run the feather across the head of the penis, then around the rim, and along the shaft on both the top and underside. A pleasurable, tickling sensation should be noted. This may or may not invoke an erection.

4. Note down and record any feelings or sensations. Does the penis respond to this stimulus in any way?

5. Next take the ice-cube, and repeat step 3 using this as the stimulus. A cold sensation should be noted, with the penis possibly shrinking or recoiling from the temperature change.

6. If there is no noted sensitivity to these stimuli or the sensitivity of the penis is minimal then it is advised that further medical advice be sought. If, however, the penis responds and sensitivity is noted then this is considered to be normal.

Increasing Penis Sensitivity

The best ways to increase penis sensitivity is to engage in activities that promote healthy cell and nerve function. This means wearing underwear and clothing that is supportive, but not restrictive, cutting down on smoking and alcohol consumption, eating a healthy balanced diet, and drinking plenty of water throughout the day. It is also suggested that a penis health crème, (health professionals recommend Man1 Man Oil), be used daily to aid in cell rejuvenation, which, in turn, increases penis sensitivity. This is attributed to the fact that these products contain essential vitamins, minerals, and amino acids that keep the penis in optimal condition.
