Vasectomy reversal is overall a very safe procedure. For this reason, it can be a very good option for men who wish to have children. It’s important to know that most vasectomy are very successful. There is no guarantee, though, that this will occur. And, even if the procedure is successful, that does not mean you will have success in conceiving a child. However, it is important to take into consideration any risks and concerns associated with this procedure before making the decision to go forward with it.
Vasectomy reversal is a very safe procedure with few threats. However, in rare situations, complications can occur. Your doctor will discuss these risks with you before you go through with the procedure. You should ask any questions you have at that time. Some of the potential risks you should know about include these:

Bleeding: Bleeding in the scrotum can occur. This leads to a hematoma, a collection of blood. This can create swelling in the area and pain. The best way to avoid this complication from occurring is to follow your doctor’s specific directions after your procedure. Rest is necessary to allow the connections to re-grow and for the incisions to heal properly. Even if you do not see blood, it can

Infections: Like any surgery, there is a risk of infection with vasectomy reversal. Generally, this is very uncommon because the incisions are very small and the procedure is done in a surgical unit. However, if you do have an infection, your doctor may recommend medications to treat it.
Chronic pain: For some men, the worst problem resulting from vasectomy reversal is chronic pain. This is not very common, but it can occur in men. It may be treatable or it may not be.
It’s important for you to take the time to talk to your doctor about any other types of medical concerns you may have that could impact your success rate or your safety through this procedure. For most men, it requires only a few weeks of downtime.

Vasectomy surgery entails cutting the vas deferens to prevent sperm from entering the ejaculate in order to produce long term sterility. (click to enlarge)
Vasectomy reversal micro-surgery entails reconnecting the two ends of the vas deferens utilizing a surgical microscope, micro-instruments and micro-sutures in order to allow the sperm to enter the ejaculate and regain fertility after vasectomy surgery.The vasectomy reversal procedure is performed by fellowship-trained urologic surgeon Matthew Wosnitzer, M.D. at the Center for Male Health and Reproduction of Connecticut. Dr. Wosnitzer has extensive specialized trainingin this procedure and is devoted toobtaining the best outcomes (patency rates) for men. Additionally Dr. Wosnitzer has conducted research and published extensively on vasectomy reversal and male infertility. Background information about vasectomy reversal, important male reproductive anatomy, and factors affecting successful outcomes are described here.

Microsurgical vasectomy reversal, also called reverse vasectomy or vasovasostomy, is performed under local, regional, or general anesthesia, most commonly general anesthesia. Incisions on each side of the scrotum are made, approximately 1 cm lateral to the base of the penis. This incision location allows for the testicles to be delivered and for exposure of the epididymis if needed (for VE) for tension-free anastomosis. Successful vasectomy reversal requires careful dissection of the vas to increase vasal remnant length without harming the vasal vessels. The vasectomy site is identified and the vas is cut on the testicular side of the vasectomy site. Although the vas was cut during vasectomy, scar is usually present and requires both ends of the cut vas to be freed for vasectomy reversal.
More detail about vasectomy reversal technique is available in Dr. Wosnitzer’s publications including thisrecently published articlein Urologic Clinics of North America. What are the possible types of vasectomy reversal depending on my condition?
Vasectomy reversal is technically done in one of two ways depending on where the blockage is located. The first, and most common way is vasovasostomy (reconnecting the vas ends) after removing the vasectomy blockage site. The second and more complex way, which is only done when there is obstruction of the epididymis, is called vasoepididymostomy, (or VE for short). VE reconnects the upper vas end to the epididymis, which is the cap on the back of the testis (where late sperm maturation occurs). See diagrams of each procedure below, followed by additional information.

Vasal fluid is checked during the operation under the microscope and findings help to select vasovasostomy (VV) or vasoepididymostomy (VE) procedure. If sperm are identified in vasal fluid, then the location of obstruction is identified and vasovasostomy (vas to vas connection) is completed. If no sperm are identified in vasal fluid, then epididymal obstruction is confirmed and VE (vas to epididymis connection) is completed. Rarely, additional obstruction can be found in the vas closer to the ejaculatory ducts which empty into the urethra (urine channel, where semen also passes out of the body). Before doing the anastomosis, confirmation that the upper vas end is patent is done by injecting fluid that does not meet resistance.
If vasovasostomy is indicated, the vas deferens tube is reconnected using amicroscope (microsurgery)orinfrequently using the Da Vinci robot) in a very precise way. The repaired vas deferens must be tension-free and watertight for the best outcome. This anastomosis is done in multiple layers usingmicrodots(small dots serve as a blueprint to mark where sutures should be placed and allow accurate realignment of the vas). Also a “scaffolding” (special approximating clamp) is used to align the ends of the vas for reconneciton. The inner (mucosal) layer is completed with special 10-0 monofilament sutures (smaller than a single human hair). The second layer (deep muscularis) is reapproximated using interrupted 9-0 monofilament sutures (slightly thicker suture, but still smaller than human hair). The third adventitial layer is also realigned using 9-0 monofilament sutures. Finally the vasal sheath is brought together with 8-0 monofilament sutures. Special techniques are used when the vas obstruction site is close to the testicle (in the convoluted vas) or when there are large vasal gaps (crossed vasovasostomy or testicular transposition may be needed).
VE is the indicated treatment for epididymal obstruction and involves the re-routing of the upper portion of the vas to the epididymis (colored orange on diagram), bypassing the obstructed lower portion of the vas. The lower portion of the vas is then no longer involved in sperm transport following surgery. VE involves delicate anastomosis between vas and epididymis compared to the vas-to-vas connection in vasovasostomy. Following the first VE in the early 1900’s with very low success, surgical technique has improved throughout the last 30 years most recently including longitudinal placement of sutures in the epididymal tubule known as longitudinal intussusception VE (LIVE) which has resulted in patency rates (successful vas reconnection) of 90% and pregnancy rates of 40%. TheLIVE techniquepermits a larger diameter for flow from epididymal tubule to vas, with better results than other techniques.
What Are The Side Effects Or Risks Of Vasectomy Reversal?
After freeing up the abdominal vas to allow tension-free anastomosis to the epididymis, the covering of the testis and epididymis (tunica vaginalis) is opened, and the epididymis is examined. Classically, dilated tubules near the testis-side of the obstruction are noted, while collapsed non-dilated tubules are found on the other side (closer to the abdomen) of obstruction. A larger diameter, straight epididymal tubule is selected and a very small opening is made in the thin covering over it (epididymal tunic). VE anastomosis is completed using an epididymal tubule with abundant sperm regardless of motility. The quality of the epididymal fluid from the selected tubule will not be known until after sutures are placed using the LIVE technique. If sperm or abundant sperm parts are absent following incision of the epididymal tubule, then epididymal obstruction is located more proximally (closer to testicle) and the sutures must be removed and the anastomosis restarted using closer to the testis.
With the LIVE technique, four microdots are placed on the vas end (indicating the exit points of the four needles), and two 10-0 monofilament nylon sutures are placed longitudinally into the epididymal tubule under x25-x40 magnification. An ophthalmic microknife (15 degree) is used to incise between the needles which are not pulled through until after incision (since leakage will occur given larger diameter of needle than suture). If abundant sperm with motility are identified in epididymal fluid, the fluid is aspirated into multiple micropipettes and cryopreserved. The anastomosis is then completed by placing the four needles inside-to-out through vasal mucosa, exiting through each microdot on the vas. After tying the 10-0 sutures, the outer layer of the anastomosis is completed with up to 12 interrupted 9-0 nylon sutures from the vasal sheath to the epididymal tunic taking care not to injure the nearby epididymal tubules. The testis and epididymis are returned to the tunica vaginalis, the testis is replaced in the scrotum, and incisions are closed.
