High‐frequency ultrasound imaging of noninvasive laser coagulation of the canine vas deferens

A noninvasive approach to vasectomy may eliminate male fear of complications related to surgery (e.g., hematoma, infection, acute and chronic pain, sterilization failure) and increase its acceptance. Noninvasive laser thermal occlusion of the canine vas deferens has recently been reported. In this study, high‐frequency ultrasound is used to confirm successful laser thermal coagulation and scarring of the vas in a short‐term canine model.
