Penis and Glans Color Changes: Myths and Facts

Regarding this statement?

Hello, Dr.
Hsu.
It's been a while.
I would like to ask if the skin color of the penis and glans can indeed become darker due to excessive friction.
There are various opinions on this issue, but from a medical perspective, friction would include contact with clothing, masturbation, and sexual intercourse, right? Additionally, I read in a book by a Japanese doctor that the bodily fluids of men and women are slightly alkaline, and applying them to the penis can increase melanin production.
Is this statement accurate?
Furthermore, there are two popular supplements in the urology field, "Beishodeng" and "Weifeng." Do you endorse these products? I have a condition of premature ejaculation, and although I have undergone circumcision, there has been no improvement.
Occasionally, I use a towel to rub the glans while showering, as I have heard this can reduce sensitivity.
However, could this potentially harm the glans over time? Besides using a towel, what other methods can help reduce sensitivity in the glans? Thank you, doctor.

Hello, in the medical field, there is very little research on this topic.
A few individuals believe that the pigmentation of the penis may be related to vaginal secretions and friction, resulting in a darker color.
However, some scholars argue that there is no correlation, and it is purely a matter of individual constitution.
Using a towel while showering to reduce premature ejaculation is supported by evidence; clinically, it poses minimal risk and rarely causes injury to the glans.
Other methods, such as the stop-start technique, involve pausing sexual activity just before ejaculation and resuming when the urge decreases, which can gradually train the sensitivity of the glans.
If there are any unclear points, feel free to ask again for further discussion and research.
Sincerely, Dr.
Hsu Wei-Kai, Director of Urology, Taitung Hospital, Department of Health, Executive Yuan.

Understanding changes in the color of the penis and glans can be a topic surrounded by myths and misconceptions. It's important to approach this subject with a clear understanding of the medical facts involved.

Firstly, the color of the skin, including that of the penis and glans, can change due to various factors, including friction. Frequent friction, whether from clothing, masturbation, or sexual intercourse, can lead to hyperpigmentation. This is a common response of the skin to repeated irritation or trauma, which can stimulate the production of melanin, the pigment responsible for skin color. Therefore, it is indeed possible for the penis and glans to appear darker due to excessive friction over time.

Regarding the claim that bodily fluids, which are slightly alkaline, can increase melanin production when applied to the penis, there is no scientific evidence to support this assertion. While it is true that bodily fluids have a pH that can influence the local environment of the skin, the idea that they can significantly alter pigmentation is unfounded. Skin pigmentation is primarily determined by genetics and the amount of melanin produced by melanocytes in the skin.

As for the products "倍碩登" and "威峰," which are marketed as supplements for male enhancement, it's crucial to approach such products with caution. The efficacy and safety of these supplements can vary widely, and many are not backed by rigorous scientific research. If you are experiencing issues such as premature ejaculation, it is advisable to consult a healthcare professional who can provide evidence-based treatments rather than relying on unverified supplements.

In terms of managing sensitivity in the glans, there are several approaches you can consider. While some individuals use towels or other materials to desensitize the area, this practice should be approached with care to avoid irritation or injury. Overly aggressive rubbing can lead to skin damage or increased sensitivity in the long run. Instead, consider the following methods:
1. Gradual Desensitization: Instead of using a towel, you might try gradually increasing exposure to different textures or sensations. This can help your body adjust without causing irritation.

2. Topical Creams: There are over-the-counter creams designed to reduce sensitivity. These typically contain numbing agents like benzocaine. However, it's essential to use these products as directed and consult a healthcare provider if you have concerns.

3. Behavioral Techniques: Techniques such as the "stop-start" method or the "squeeze" technique can help manage sensitivity during sexual activity. These methods involve pausing stimulation before ejaculation to help increase control over time.

4. Consultation with a Specialist: If sensitivity remains a significant issue, consider consulting a urologist or a sexual health specialist. They can provide tailored advice and treatment options based on your specific situation.

In conclusion, while changes in the color of the penis and glans can be influenced by friction and other factors, many myths surround this topic. It's essential to rely on scientific evidence and consult healthcare professionals for accurate information and effective treatment options. Always prioritize your health and well-being by seeking professional guidance when dealing with sensitive issues.
