Testing has been successful in rabbits with excellent wound healing, complete vas occlusion on histology, and no sperm in post procedural semen analysis. The study data was presented last year as a video submission and subsequently won the AUA 2022’s “Best Video” of the andrology/infertility/sexual dysfunction session. Further studies in larger animals were indicated and FDA-approval are needed before its application in humans. The issue of “does the SVP effectively seal the vas deferens in animals larger than a rabbit and in humans?” is a critical one for treating physicians. Evaluate the effectiveness of the SVP in sealing the vas deferens in animals larger than a rabbit and in humans. METHODS: Animal (rabbit) studies have been previously described. We preformed microscopic evaluation of the vas deferens tissues from canines treated with the SVP at either 40 or 60 watts, euthanized at 14 days post-treatment under the conditions of this study. Human vas deferens specimens after removal from the patient were then immediately treated with SVP tool on benchtop. Porcine vas deferens samples were procured and underwent benchtop testing. Specimens were sent for pathologic evaluation by a third-party professional vendor [Crisp County Regional Medical Center in Cordele, Georgia]. RESULTS: 4 canine, 6 human, and 26 porcine vas deferens were included in SVP testing. Human, porcine, and canine specimens demonstrated tissue coagulation and fibrosis in the treated vasa deferentia. (See Figure 1 Human and Figure 2 Canine) CONCLUSIONS: SVP is a potentially exciting novel vasectomy procedure that appears to provide good sealing of the vas deferens in the canine animal model and on benchtop for the human and porcine vas deferens. FDA-approval is still needed before use in humans.
