Does Low Testosterone Cause Peyronie's Disease?

Peyronie’s disease is a condition in which there are fibrotic plaques (sometimes calcified) that can cause a curvature in the penis, most notable during erection. Pain as well as urinary and sexual dysfunction may occur with Peyronie's disease. Increased attention has been given in recent years to the relationship between male hormones, erectile dysfunction, and Peyronie's disease. According to the Mayo Clinic, testosterone, the predominant hormone affecting male physical characteristics, peaks during adolescence and early adulthood. Testosterone gradually decreases about 1% per year once a man reaches age 30-40. Some men experience symptoms from the decline in testosterone and these symptoms can include decreased sexual function, sleep disturbances changes in bone density and muscle bulk, as well as changes in cognition and depression. Because other factors and conditions can cause similar symptoms, patients with any of these changes should talk to their medical provider to rule out diabetes, thyroid dysfunction, depression, sleep apnea, and medication side effects, according to Mayo.

In an article published in 2012, Iacono and colleagues studied the correlation between age, low testosterone, fibrosis of the cavernosal tissues, and erectile dysfunction. 47 patients diagnosed with erectile dysfunction (ED) were included, with 55% of the 47 men being older than age 65. Having increased fibrosis corresponded to having a positive Rigiscan test- meaning that a nocturnal test of penile rigidity demonstrated abnormal nighttime erections. Low levels of testosterone also corresponded to erectile dysfunction. (This is an open access article with full text available) Another published article agreed with the above in that low testosterone is associated with Peyronie’s disease and/or erectile dysfunction. The authors are cautious, however, in describing the association between the variables, as causation towards plaque formation characteristic of Peyronie’s is not known.

The larger question about Peyronie’s disease is what a patient can do to improve the symptoms of the condition. Therapists who treat male patients are increasingly interested in this question, and many are working with their patients to address the known soft tissue dysfunction. Interventions may include teaching patients to perform soft tissue mobilizations and stretches to the restricted tissue, and educating the patient in what the available literature tells us about rehabilitation of this condition. Hopefully, as male pelvic rehabilitation continues to grow in popularity, more therapists will contribute case studies and participate in higher levels of research so that more men can add conservative care of Peyronie’s to their list of treatment options.
