Learning to Palpate the Child's Testicles Using Simulation

Hypothesis is that better training of medical students in the examination of boy's external genitalia could improve the diagnosis of testicular position anomalies. To this end, investigators already have created a model to train testicle palpation and recognition of testicular position anomalies. So investigator set up a monocentric randomized controlled trial in wich the medical students will be randomized into 2 groups : a control group receiging only book-based theoretical instruction on the examination of the external genitalia and testicular position anomalies, and a mannequin group receibing, in addition to this conventionnal instruction, simulation training on the mannequin Medical students will then attend a consultation with a child whose reason for coming to the hospital is a testicular positioning anomaly. Students clinical examination will be scored by the consulting senior, and the final diagnosis retained by the student will be compared with that retained by the consulting senior. The aim is to show that medical students who have trained on this new model are better, in terms of clinical examination and diagnostic, than students in the control group.
