Is secondary hyperplasia of corpus cavernosum possible?

Secondary hyperplasia of the corpus cavernosum is extremely rare in medicine and is usually caused by pathological factors such as trauma, abnormal hormonal stimulation, or chronic inflammation. The main triggers include recurrence of Peyronie's disease, abnormal androgen levels, local blood circulation disorders, post-traumatic fibrosis, and specific drug side effects.

1. Recurrence of Peyronie’s disease:

After treatment for Peyronie's disease and Peyronie's disease, fibrous plaque hyperplasia may reappear due to abnormal collagen metabolism. This condition is often accompanied by painful erections or curvature of the penis and needs to be diagnosed with an ultrasound. Collagenase injection or low-intensity shock wave treatment is commonly used clinically. In severe cases, surgical removal of plaque is required.

2. Abnormal hormone levels:

Oversensitivity of androgen receptors or inappropriate testosterone replacement therapy may lead to abnormal proliferation of cavernous cells. Such patients are often accompanied by signs of masculinization such as increased body hair and acne, and hormone levels need to be evaluated through endocrine examinations. Adjusting hormone therapy or using 5α-reductase inhibitors can effectively control the disease.

3. Local circulation disorders:

Microvascular disease caused by long-term diabetes or hypertension can lead to hypoxia in the corpus cavernosum and stimulate compensatory proliferation of smooth muscle. Typical manifestations include decreased nighttime erections and decreased erection hardness, and Doppler examination of penile blood flow can confirm the diagnosis. Improving underlying diseases and combining PDE5 inhibitors can alleviate symptoms.

4. Post-traumatic fibrosis:

Penile trauma or multiple surgeries may trigger excessive scarring and stimulate fibrous tissue proliferation through the TGF-β signaling pathway. Most of these patients have a clear history of trauma, and abnormal signal foci can be seen in MRI examination. Physical therapy combined with hyaluronic acid injections can improve tissue elasticity.

5. Effects of special drugs:

Long-term use of prostaglandin E1 cavernosa injections or certain antidepressants may cause changes in the structure of the cavernosa. Drug-induced hyperplasia usually progresses slowly and is mostly reversible after drug withdrawal. The medication regimen needs to be gradually adjusted under the guidance of a doctor.

It is recommended that people with symptoms of abnormally enlarged cavernous bodies seek medical attention as soon as possible to investigate the cause. In daily life, you should avoid external impact on the penis area, control blood sugar and blood pressure within the normal range, and quit smoking and limit alcohol consumption to maintain good vascular status. Moderate aerobic exercise such as brisk walking and swimming can improve pelvic blood circulation. Increase the intake of deep-sea fish and dark vegetables in the diet to supplement omega-3 fatty acids and antioxidants. Conduct regular men's health check-ups, especially those over 40 years old need to pay attention to hormone levels and prostate health. When persistent erectile dysfunction, pain or morphological changes occur, you should immediately seek treatment at a urology department to avoid delaying treatment.
