This public education video by leading Urologists teaches men how to accurately measure their own penis. The video is aimed at men who are concerned about the size of their penis, and clinicians who may be working with them. CONCERNED ABOUT YOUR PENIS??? Researchers at Kings College London and South London and Maudsley NHS Foundation Trust are looking to recruit male volunteers from the age of 18 upwards who HAVE concerns about the size, shape or appearance of their penis, to take part in a randomised controlled trial. 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. You will receive £20 worth of shopping vouchers in acknowledgement of the time and effort taken to participate. 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. An assessment of the length of your penis would be carried out by a clinician when you first start the study, then again after 4 months and one year later.
