Multi Layer Microdot Vasovasostomy Step 5

Multi-Layer Microdot Vasovasostomy

Step 5

Professor Goldstein developed the Multi-layer microdot reversal (MMMV) at New York’s Cornell University to improve reversals' pregnancy rates and make them as humanly possible as free from scarring as possible. The most important layer is the connection of the innermost layer (called the mucosal layer). This helps to align the vas's extremely thin inner canal (lumen) in the perfect manner possible. 

Here is how it works. Of course, the dimensions of the vas are so small that special instruments have been developed for our use. First, six microscopic ink dots are placed on the ends of the vas to be joined, each at the same distance from the skin of the sperm channel. Next, the micro stitch needle is placed through the opposing dots on both ends, and the stitch is tied together. This technique combines the skin layer of the vas very accurately, opening up the narrow end of the vas and gently narrowing the wide testicular end resulting in a smooth, step-free join that is wide open, allowing the maximum number of high-quality sperms to pass through. Because there are no rough edges in the joint, it is less likely for scar tissue and closure to form.
