Penile fibrosis refers to areas of scar tissue that may reduce penile elasticity and be associated with penile curvature, pain or changes in sexual function.
Fibrosis is a condition characterized by the excessive formation of fibrous tissue. When this tissue develops in the penis, it may be associated with anatomical changes, pain or difficulty with sexual activity, depending on the location, extent and progression of the condition.
Penile fibrosis can arise for several reasons, and the diagnosis should be made by a qualified physician, usually in a urology setting. If suggestive signs are present, medical assessment is recommended. Timely assessment may help characterize the condition and guide options for monitoring or treatment, when necessary.
What is penile fibrosis?
Penile fibrosis is the accumulation of fibrous tissue in the tunica albuginea.
Fibrous tissue is mainly composed of collagen. Under normal circumstances, it is part of the structure of the tunica albuginea and contributes to its strength and elasticity. In fibrosis, however, there is excess collagen deposited in an abnormal and rigid way.
This excess fibrous tissue may reduce the elasticity of the tunica albuginea and limit expansion during erection, causing deformities that, in some cases, become more evident when the penis is erect. In more severe situations, penile curvature may make penetration during sexual intercourse difficult. This condition may be associated with Peyronie’s disease.
An analogy that helps explain what fibrosis does to the penis is to imagine a balloon with a strip of adhesive tape attached to its surface. When inflated, the area covered by the tape does not expand and becomes deformed.
In some cases, fibrosis of the tunica albuginea may also affect the ability to maintain an erection by making it more difficult to retain blood in the corpora cavernosa, with an impact on penile rigidity and sexual function.
What causes penile fibrosis?
Penile fibrosis may be associated with repeated microtrauma, although it is not always possible to identify a single cause. These microtraumas may occur in different contexts, such as:
- Falls;
- Accidents during sports activities;
- More vigorous sexual activity;
- Masturbation;
- Erections with the penis positioned laterally, including during sleep;
- Lack of lubrication during penetration;
- Very tight underwear.
However, penile fibrosis may also be associated with other conditions, such as:
- Diabetes;
- High blood pressure;
- High cholesterol;
- Pelvic surgery, such as prostate removal surgery.
Types of penile fibrosis
Penile fibrosis may present with different locations, extents and associated features:
- Tunica albuginea fibrosis: Corresponds to the most classic form, with formation of a fibrotic plaque in the tunica albuginea, which may cause upward, lateral and/or downward curvature, pain and possible functional impact.
- Intracavernosal fibrosis: Extends into the corpora cavernosa and may affect expansion, penile rigidity and erectile function. In general, this type of fibrosis may be associated with penile narrowing.
- Localized fibrosis: May form at a single point of the penis, such as the base, shaft or glans, resulting in tortuosity or narrowing.
- Diffuse fibrosis (2 or more points): Occurs when fibroses develop in multiple regions, which may lead to several deformities, such as two or more curvatures and/or areas of narrowing.
- Plaque calcification: An associated feature that may be present on the upper surface, lateral surfaces or distal end of the organ, especially in more chronic phases.
It is important to note that signs suggestive of penile fibrosis should prompt medical assessment, and monitoring or treatment measures may be considered according to the diagnosis and clinical progression.
How to identify penile fibrosis?
The diagnosis of penile fibrosis should be made by a urologist. However, observing changes in the penis and careful palpation may help a man recognize suspicious signs, without replacing medical assessment.
During self-observation, changes in the organ should be assessed, namely hardened or nodular areas, as follows:
- With the penis flaccid: gently traction the organ by the glans, observe it and palpate it along its length,
- With the penis erect: observe whether there is curvature, narrowing, shortening or another acquired deformity.
It should be noted that not all penile fibrosis is easily identified by palpation. In some cases, there may be loss of elasticity or lesions that are not very evident on physical examination.
If these signs are present, assessment by a urologist is recommended; the physician may consider the need for additional diagnostic tests according to the case.
Common symptoms of penile fibrosis
- Penile curvature or deformity during erection;
- Pain during erection or sexual activity;
- Difficulty obtaining or maintaining an erection (erectile dysfunction).
Does penile fibrosis cause pain?
Penile fibrosis may cause pain, depending on the phase of the condition.
When it is in the acute or initial phase, it may cause pain during erection.
Pain intensity may vary. Some men may feel only mild discomfort, while others may experience more intense pain.
In the chronic phase, the scar tissue may remain sensitive or become painful to palpation.
The presence of pain should prompt medical assessment, preferably in a urology consultation, to understand the possible causes and define the most appropriate clinical guidance for the case.
I have penile fibrosis, what now?
After suspected penile fibrosis, it is recommended to seek assessment by a urologist. The physician may consider specific tests, including assessment with induced erection in some cases, to characterize the type, extent and severity of the fibrotic plaque, as well as penile vascularization.
In mild cases, without significant deformity or relevant functional impairment, clinical monitoring or a therapeutic approach to limit the progression of curvature may be sufficient.
In more advanced cases, with marked deformity or impairment of sexual function, a surgical approach may be indicated.
It is important to note that seeking medical guidance at the first symptoms may favor timely assessment and allow the most appropriate management to be defined according to the phase of the condition.
Treatment options for penile fibrosis
There are different treatment options for penile fibrosis, which may be considered according to the severity of the condition, the phase of the disease and the impact on sexual function.
In the initial phase, fibrosis may be associated with pain, and symptomatic control measures may be considered, including analgesics when clinically indicated. Depending on clinical progression, the urologist may consider pharmacological approaches, although the evidence is variable, with the aim of monitoring the evolution of curvature and trying to reduce its progression.
In addition, at this stage, the physician may guide the patient on care during sexual activity, such as choosing positions that reduce discomfort or the risk of trauma, using adequate lubrication and avoiding forced penetration, according to the individual clinical situation.
When curvature progresses or fibrosis enters a stable cicatricial phase, a surgical approach may be indicated.
As the fibrotic plaque evolves, penile deformity may become more pronounced and erection may become more difficult in some patients. In these cases, the surgical procedure may aim to reduce curvature and improve penile anatomy, respecting the anatomical and functional limits of each case.
In addition to addressing the deformity, in some cases associated with erectile dysfunction, surgery may include placement of a penile implant, which may contribute to penile rigidity during sexual intercourse, depending on clinical indication, device function and patient adaptation.
However, if the fibrosis stabilizes at an angle that does not compromise sexual life, the medical recommendation may be limited to clinical surveillance and monitoring of progression.
Is it possible to maintain sexual activity with penile fibrosis?
In some cases, it may be possible to maintain satisfactory sexual activity, depending on the location of the fibrosis, the degree of deformity, erectile function and the clinical approach indicated by the urologist.
However, it is important to assess whether the fibrosis is localized and whether the deformity caused does not interfere with penile rigidity or cause frequent loss of rigidity during penetration.
It is also important to maintain sexual health care and seek medical guidance for persistent changes, in order to reduce factors that may contribute to trauma or worsening of the condition, according to the individual clinical situation.
Medical assessment of penile fibrosis
Penile fibrosis is a condition that should be assessed in a timely manner, especially when it causes pain, curvature or changes in sexual function. There are different monitoring and treatment options, according to the phase of the disease, the severity of the deformity and the impact on sexual life.
If there are symptoms compatible with those described, assessment by a urologist is recommended. For clarification of doubts and individual clinical assessment, you may request information about a specialist medical consultation.
