European Association of Urology Guidelines on Penile Size Abnormalities and Dysmorphophobia: Summary of the 2023 Guidelines

Abstract

Context

Recommendations regarding the management of penile size abnormalities and dysmorphophobia are important in guiding evidence-based clinical practice.

Objective

To present a summary of the 2023 European Association of Urology sexual and reproductive health evidence-based recommendations for the management of penile size abnormalities and dysmorphophobia.

Evidence acquisition

A broad and comprehensive scoping exercise covering all areas of the guidelines was performed. Databases searched included Medline, EMBASE, and the Cochrane Libraries. A level of evidence and a strength of recommendation were assigned for each recommendation according to the evidence identified. The evidence cutoff date for the 2023 guidelines is June 1, 2022.

Evidence synthesis

Well-structured studies reporting high level of evidence, with standardized PROMS were deficient on penile size abnormalities and dysmorphohobia. A shared definition for short penis/micropenis was also lacking. Categorisation of penile abnormalities according to congenital, acquired, and dysmorphophobic aetiology is deemed compulsory. A detailed medical and psychosexual history and precise measurements of penile size are essential in the diagnostic pathway. Patients with normal penile size who are seeking penile augmentation should be referred for psychological evaluation for potential dysmorphophobic disorders. Penile length and girth enhancements can be achieved via a multitude of treatments, but a personalised management plan is crucial for satisfactory results. Endocrinological therapies, when indicated, are effective in the prepubertal setting only. Vacuum therapy has a limited evidence base in treatment protocols, although acceptable outcomes have been reported for penile traction therapy. Surgical techniques to enhance penile length and girth have limited evidence and should only be proposed after extensive patient counselling.

Conclusions

Management of penile abnormalities and dysmorphophobia is a complex issue with considerable ethical concerns. The adoption of a structured diagnostic and therapeutic pathway is crucial, as recommended in the guidelines.

Patient summary

Requests for medical/surgical treatments to increase penis size have increased dramatically worldwide. Several conservative and surgical treatments are available. However, few patients receive clear information on the benefits and possible harms of these treatments. These guidelines aim to provide a structured path to guide both physicians and patients in the selection of appropriate treatment(s) to increase penis size.
