Penile Curvature

This condition, also known as Peyronie's disease, is a phenomenon faced by many men. It is a deformity of the penis in which an abnormal curvature occurs during erection. This curvature can vary in severity, from mild to significant, and can cause physical and psychological discomfort. The peculiarity of this condition lies in its heterogeneity. While some people may experience penile curvature only once and transiently, for others, this condition can become recurrent and persistent over time. This phenomenon can profoundly affect an individual's sexual life and self-confidence.

Anatomical and Congenital Causes

One of the main causes of penile curvature is represented by anatomical and congenital factors. This means that the anatomical structure of the penis or differences in the development of penile tissues can contribute to this condition. In particular, penile curvature can result from:

  • Asymmetries in the structure of the corpora cavernosa. The corpora cavernosa are two cylindrical structures inside the penis that fill with blood during erection, causing the penis to enlarge and become rigid. If these tissues do not develop uniformly or if there are differences in their structure or length, this can lead to curvature during erection.

  • Congenital fibrosis. In some cases, a condition called congenital fibrosis may be present from birth. This fibrosis can affect the tissues of the penis, causing curvature when the penis becomes erect.

  • Alterations in penile development. During fetal development, the penis may undergo alterations or deviations in the development of its tissues. These variations can lead to curvature when the penis is erect.

**It is important to note that these anatomical and congenital causes can be present from birth or may develop over time

. Additionally, they can vary greatly from person to person, thus contributing to the diversity of penile curvature experiences. For those suffering from this condition, accurate diagnosis and consultation with a specialist like Prof. Castiglione can be crucial in effectively addressing the situation and finding personalized solutions.

Penile curvature can also be caused by trauma or injuries to the penis that result in scarring or damage to the tissues. These traumas can include:

  • Previous surgical intervention. In some cases, a previous surgical procedure on the penis, such as a procedure to correct another condition, might cause scarring or alterations in the penile structure that lead to curvature during erection.

  • Distortion trauma. Direct trauma to the penis, such as a blow or a fall, can cause injuries to the penile tissues. These injuries can include damage to the corpora cavernosa or the nerves responsible for erection. The scars that form during the healing process can affect the shape of the penis in erection.

  • Forced or aggressive sexual intercourse. Experiencing forced or particularly aggressive sexual intercourse can cause injuries to the penis. The damage to the tissues can contribute to the appearance of penile curvature.

It is important to note that, although these causes are associated with physical trauma, penile curvature can also occur in the absence of evident trauma. In some cases, the tissue damage can be microscopic but still sufficient to cause curvature during erection.

Peyronie's Disease

Peyronie's disease is a condition characterized by the formation of fibrous scar tissue in the erectile tissue of the penis. This fibrosis can lead to an abnormal curvature of the penis during erection, often accompanied by pain or discomfort.

Risk factors for the development of Peyronie's disease include:

  • Age. This condition more commonly affects middle-aged or older men, although it can occur at any age.

  • Family history. Genetic predisposition may play a role in its development, and sometimes multiple family members may be affected.

  • Repeated trauma. Trauma to the penis caused by vigorous sexual intercourse or other activities can increase the


  • Autoimmune diseases. Some autoimmune diseases, like Dupuytren's contracture, have been associated with Peyronie's disease.

  • Lifestyle and sexual habits. Factors such as smoking and alcohol abuse can increase the risk of developing this condition.

  • Concomitant pathologies. Certain medical conditions, like diabetes or connective tissue diseases, may be associated with a higher risk.

Peyronie's disease can vary greatly in severity, with some people experiencing only a slight curvature and others experiencing a significant and painful curvature.

Inflammatory Processes of the Penile Skin (Balanoposthitis)

Balanoposthitis is a condition characterized by inflammation of the head of the penis (glans) and the foreskin. This inflammatory process can be caused by various sources, including bacterial, fungal infections, or irritations from chemicals. If not properly treated, balanoposthitis can lead to several problems, including the retraction of penile tissues.

Here's how the inflammatory processes of the penile skin can contribute to tissue retraction:

  • Inflammation and Swelling. During an episode of balanoposthitis, the penile tissues can become inflamed and swollen. This swelling can make it difficult to retract the foreskin, causing discomfort and tension.

  • Scar Formation. If the inflammation persists or occurs frequently, it can lead to the formation of scars or fibrous tissue. These scars can constrict the penile skin, affecting its mobility and causing curvature or retraction during erection.

  • Pain and Discomfort. The inflammation and swelling associated with balanoposthitis can cause pain during erection. The discomfort can lead to an involuntary retraction of tissues as a protective reaction.

It's important to emphasize that balanoposthitis is a treatable condition and that timely treatment can prevent the progression of symptoms and worsening of tissue retraction.


Lifestyle can play a significant role in sexual health and the onset of conditions like penile curvature. Here's how certain lifestyle factors can influence the underlying inflammatory mechanisms:

  • Tobacco Smoking. Tobacco smoking is known to have negative effects on blood circulation and vascular health. Vascular damage can affect the penis's ability to achieve and maintain a full erection, potentially contributing to penile curvature as blood flow may be compromised.

  • Alcohol Consumption. Excessive alcohol consumption can negatively affect erectile function and increase the risk of inflammatory conditions. Alcohol can also contribute to obesity, which is further associated with inflammatory disorders and can affect sexual health.

  • Anxiety and Stress. Anxiety and chronic stress can trigger inflammatory responses in the body. These psychological states can also contribute to erection problems and affect penile curvature due to muscle tension and physiological reactions.

  • Obesity. Obesity is often associated with chronic inflammatory processes. Excess weight can affect vascular and hormonal function, contributing to the inflammatory mechanisms that can affect penile tissues.

Quitting smoking, limiting alcohol consumption, managing stress, and maintaining a healthy body weight can help improve sexual health and reduce the risk of conditions like penile curvature.

Intrinsic Therapies

Some medications and intrinsic therapies can impact male sexual health and, in some cases, contribute to the appearance of penile curvature. Here's how some of these therapies can affect this phenomenon:

  • Beta-blockers. Beta-blockers are a class of drugs primarily used to treat hypertension and cardiovascular conditions. However, in some cases, they can cause erection problems or contribute to difficulties in managing an erection. These side effects may be related to the effects of beta-blockers on blood circulation and the vascular response of the penis.


Vasculopathies, or vascular disorders, can have a significant impact on male sexual health and, in some cases, can contribute to the appearance of penile curvature. An important example of vasculopathy is hypertension, or high blood pressure. Here's how vasculopathies, particularly hypertension, can be related to penile curvature:

  • Vascular Alterations. Hypertension can cause changes in blood vessels, including those that supply the penis. These alterations can affect blood circulation to the corpora cavernosa of the penis, which are responsible for erection. Compromised blood circulation can lead to erection problems and, in some cases, contribute to penile curvature.

  • Reduced Blood Flow. Hypertension can reduce blood flow to the penis during erection. This can make it more difficult to achieve and maintain a full erection. Additionally, reduced blood flow can affect the structure of the erectile tissues of the penis and contribute to curvature.

  • Stress on Tissues. Hypertension can increase stress on the tissues of the penis during erection. This continuous stress can affect the structure of the tissues and contribute to penile curvature.

Advanced Age

Aging is an important factor to consider when exploring the causes of penile curvature. As men age, physiological changes occur that can increase the risk of developing chronic inflammatory diseases and, in some cases, contribute to penile curvature. Here's how advanced age can affect penile curvature:

  • Cellular Changes. With aging, the cells of the body undergo changes. These changes can include an increase in chronic low-grade inflammation, known as "inflammaging." This type of inflammation can affect various tissues, including

those of the penis.

  • Fibrosis and Rigidity. Chronic inflammation can contribute to fibrosis, which is the formation of scar tissue. In the case of the penis, fibrosis can cause a loss of flexibility and increased rigidity of the erectile tissues. This can lead to penile curvature during erection.

  • Systemic Diseases. With advancing age, the risk of developing chronic diseases such as diabetes, hypertension, and cardiovascular diseases also increases. These conditions can affect blood circulation and vascular health in the penis, contributing to erection problems and, in some cases, penile curvature.

It's important to note that not all older men will develop penile curvature, and aging is not the only possible cause.

Idiopathic Origin

In some cases, penile curvature can have an idiopathic origin, which means that the cause remains unknown despite clinical examinations and medical evaluations.

This is a significant challenge for both patients and medical professionals, as it can be difficult to identify a specific cause or triggering factor.

Here are some important considerations regarding the idiopathic origin of penile curvature:

  • Anatomical Complexity: The penis is a complex organ with numerous tissues, blood vessels, nerves, and structures contributing to its erectile function and anatomy. In some cases, complex variations or interactions among these factors can lead to curvature without a specific cause being identified.

  • Multifactorial Factors: Penile curvature can be influenced by a combination of factors, including genetics, personal anatomy, predisposition to inflammation or fibrosis, and other unknown factors. This complexity can make it challenging to pinpoint a single cause.

  • Diagnostic Exclusions: To confirm an idiopathic origin, doctors often rule out other possible causes, such as Peyronie's disease or congenital issues. If all these other causes have been excluded through appropriate examinations and evaluations, and the curvature persists, an idiopathic origin can be considered.
