Training using a simulation-based workshop reduces inaccuracies in estimations of testicular volume.

Objectives: Measuring testicular volume (TV) by orchidometer is routine in the clinic when staging male puberty. We have developed a simulation model for TV estimation and investigated whether training medical students, using a workshop with simulation models, could improve the accuracy and reliability of TV estimation.

Methods: All participating medical students watched a video representing standard undergraduate training in male pubertal assessment.
