Peyronie’s disease and testosterone deficiency: Is there a link?
Peyronie’s disease (PD) and testosterone deficiency (TD) impact men at the same stage of life and can ultimately contribute to erectile dysfunction. There is speculation that low levels of testosterone (T) may predispose men to penile fibrosis; however, there is no published, up-to-date review summarizing the current evidence. Therefore, we conducted a narrative review of the literature exploring the relationship between PD and TD.
A comprehensive systematic search of existing literature of five online databases from June 1990 to June 2018 examining the relationship between PD and TD was conducted. The Cochrane risk-of-bias tool for randomized trials and the risk-of-bias assessment tool for cohort studies were used to evaluate the quality of studies.
Six studies were identified (n = 675). Overall, five studies supported the link between PD and TD by demonstrating relationships in PD patients with low total T, free T, bioavailable T, greater penile curvature, and plaque development. However, one study demonstrated no connection between the conditions. The literature is restricted by small studies with methodological flaws.
There are a number of mechanisms to support the link between TD and PD. The literature on the topic is limited by small studies which are overall conflicting. The findings of this work suggest the need for larger, prospective studies to clarify the role of TD in the development, evaluation, and treatment of PD. Establishing such a relationship could change management of PD as a diagnosis of PD may encourage clinicians to evaluate a patient’s testosterone levels.
