Research on men worried by size


The aim of this study is to help us better understand what makes some men dissatisfied with the size of their penis. For these men, this study will hopefully help us find the best way of helping them so they are satisfied.

We are looking to recruit male volunteers from the age of 18 upwards who HAVE concerns about the size, shape or appearance of their penis or testicles.

The study involves completing a number of online questionnaires about body image, sexual satisfaction and other health-related measures, which will take about an hour. You would then come to Kings College London Hospital Urology department clinic to have your penis measured (both erect and non-erect). You will then be randomised and asked to either wear a traction device with some brief counselling for four months OR receive brief counselling only, with the option of wearing the traction device after 4 months if you are still concerned about your size.

The trial is to help us decide what treatment is the most effective for men who are very concerned about the size or shape of their penis. Whichever group you are allocated to, an assessment of the length of your penis will be carried out by a clinician when you first start the study, after 4 months and after one year.
