Does Wearing Tight Underwear Cause Permanent Curvature in the Penis? - Urology

Erection


Hello, doctor.
I would like to ask if wearing tight underwear (like briefs) for a long time can really cause the penis to become more curved when it is erect? I have seen this claim online.
When I am erect, my penis bends downwards at a 45-degree angle (instead of pointing straight out).
I strongly suspect that this is due to wearing briefs during my developmental years, as many people have switched to boxers.
I believe that the tightness may have caused pressure, preventing my penis from "lifting" properly, and over time, it has become fixed in this position.
Is this true? Does a 45-degree angle affect sexual intercourse (I am a virgin)? I am worried that my future girlfriend might think my penis looks strange.
Thank you, doctor, for clarifying this for me.

Hello, it is possible that wearing tight-fitting underwear may have a slight effect on the curvature of the penis, but this impact is minimal.
Most of the curvature is still due to congenital tissue discrepancies.
If underwear could significantly influence the curvature, we could invent special underwear specifically designed to correct penile curvature.
Generally, a curvature greater than 30 degrees, or pain during erection, is recommended for surgical correction.
You mentioned a 45-degree curvature; I am curious how you measured that.
A 45-degree curvature is quite severe, and such cases are rarely seen in clinical practice.
If it is indeed measured at 45 degrees, it would likely affect sexual intercourse.
If there are any unclear points, feel free to ask again for further discussion and research.
Sincerely, Dr.

Wearing tight underwear, such as briefs, has been a topic of concern for many regarding its potential effects on penile curvature. While there are various opinions circulating on the internet, it is essential to approach this topic with a clear understanding of anatomy and physiology.

Firstly, it is important to note that the penis is composed of erectile tissue, blood vessels, and connective tissue, which allows it to become erect. The curvature of the penis can be influenced by several factors, including genetics, hormonal levels, and the presence of any underlying medical conditions. In most cases, a slight curvature during an erection is normal and varies from person to person.

Regarding the concern that wearing tight underwear could cause permanent curvature, there is limited scientific evidence to support this claim. While tight clothing may cause temporary discomfort or restrict blood flow, it is unlikely to lead to permanent changes in the structure of the penis. The penis is quite resilient, and its shape is primarily determined by genetic factors rather than external pressure from clothing.

However, prolonged pressure or trauma to the penis, such as from very tight underwear or vigorous activities, could potentially lead to conditions like Peyronie's disease. This condition is characterized by the development of fibrous scar tissue inside the penis, which can cause curvature and pain during erections. It is essential to differentiate between normal anatomical variations and pathological conditions that may require medical attention.

In your case, a 45-degree downward curvature during an erection is not uncommon and may not necessarily indicate a problem. Many men have varying degrees of curvature, and it does not inherently affect sexual function or pleasure. It is crucial to focus on overall sexual health rather than fixating on the angle of curvature. If you are concerned about the curvature or if it is accompanied by pain, difficulty during intercourse, or changes in erectile function, it would be advisable to consult a healthcare professional for a thorough evaluation.

As for the impact of your underwear choice, if you find that wearing tight underwear causes discomfort or restricts movement, it may be beneficial to switch to looser-fitting options, such as boxers or boxer briefs. This change can enhance comfort and allow for better blood circulation, which is important for erectile health.

In summary, while tight underwear may cause temporary discomfort, it is unlikely to lead to permanent curvature of the penis. A slight curvature is normal and varies among individuals. If you have concerns about your penile curvature or any related issues, seeking advice from a healthcare provider is the best course of action. They can provide personalized guidance and reassurance based on your specific situation. Remember, sexual health encompasses a wide range of factors, and open communication with partners is key to a fulfilling sexual experience.
