There are several excellent vasectomy models that can help learners get the feeling for the steps of a vasectomy before starting cases with live patients.
Two models, the bicycle-inner-tube model and the Weissman model provide good practice for most steps of a vasectomy at very low cost.
A model from the Université Laval is coming out in the next year or so that provides an extremely realistic feel of the skin, vasa, and fascia. We await this model with anticipation.
