Editing Vasectomy (section)

===Other techniques===
The following vasectomy methods have purportedly had a better chance of later reversal but have seen less use by virtue of known higher failure rates (i.e., recanalization). An earlier clip device, the VasClip, is no longer on the market, due to unacceptably high failure rates.<ref>{{cite journal |pmid=17070280 |year=2006 |last1=Levine |first1=LA |last2=Abern |first2=MR |last3=Lux |first3=MM |title=Persistent motile sperm after ligation band vasectomy |volume=176 |issue=5 |pages=2146–8 |doi=10.1016/j.juro.2006.07.028 |journal=The Journal of Urology}}</ref><ref>{{cite web |url=http://www.imccoalition.org/newsletter/2008_August_public.htm |title=Male Contraception Update for the public - August 2008, 3(8) |publisher=Imccoalition.org |access-date=2011-12-28 |url-status=dead |archive-url=https://web.archive.org/web/20120327213833/http://www.imccoalition.org/newsletter/2008_August_public.htm |archive-date=2012-03-27 }}</ref><ref name="vasweb">{{cite web |url=http://www.vasweb.com/vasclip.htm |title= VasClip|website=www.vasweb.com |archive-url=https://web.archive.org/web/20111019201121/http://www.vasweb.com/vasclip.htm |archive-date=2011-10-19}}</ref>{{Unreliable medical source|date=July 2011}}

The VasClip method, though considered reversible, has had a higher cost and resulted in lower success rates. Also, because the vasa deferentia are not cut or tied with this method, it could technically be classified as other than a vasectomy. Vasectomy reversal (and the success thereof) was conjectured to be higher as it only required removing the Vas-Clip device. This method achieved limited use, and scant reversal data are available.<ref name="vasweb" />

====Vas occlusion techniques====
{{main|Vas-occlusive contraception}}
* '''Injected plugs:''' There are two types of injected plugs which can be used to block the vasa deferentia. [[Medical-grade]] polyurethane (MPU) or medical-grade silicone rubber (MSR) starts as a liquid polymer that is injected into the vas deferens after which the liquid is clamped in place until is solidifies (usually in a few minutes).<ref>{{cite web|url=http://malecontraceptives.org/methods/mpu.php |title=Injected plugs |publisher=MaleContraceptives.org |date=2011-07-27 |access-date=2011-12-28}}</ref>
* '''Intra-vas device:'''  The vasa deferentia can also be occluded by an intra-vas device (IVD). A small cut is made in the lower abdomen after which a soft silicone or urethane plug is inserted into each vas tube thereby blocking (occluding) sperm.  This method allows for the vas to remain intact. IVD technique is done in an out-patient setting with local anesthetic, similar to a traditional vasectomy. IVD reversal can be performed under the same conditions making it much less costly than [[vasovasostomy]] which can require general anesthesia and longer surgery time.<ref>{{cite web|url=http://www.malecontraceptives.org/methods/shug.php#refs |title=Intra Vas Device (IVD) |publisher=MaleContraceptives.org |access-date=2011-12-28}}</ref>

Both vas occlusion techniques require the same basic patient setup: local anesthesia, puncturing of the scrotal sac for access of the vas, and then plug or injected plug occlusion. The success of the aforementioned vas occlusion techniques is not clear and data are still{{when?|date=May 2025}} limited.  Studies have shown, however, that the time to achieve sterility is longer than the more prominent techniques mentioned in the beginning of this article. The satisfaction rate of patients undergoing IVD techniques has a high rate of satisfaction with regard to the surgery experience itself.<ref>{{cite journal |last1=Cook |first1=LA |last2=Van Vliet |first2=HA |last3=Lopez |first3=LM |last4=Pun |first4=A |last5=Gallo |first5=MF |title=Vasectomy occlusion techniques for male sterilization. |journal=The Cochrane Database of Systematic Reviews |date=30 March 2014 |volume=2014 |issue=3 |pages=CD003991 |doi=10.1002/14651858.CD003991.pub4 |pmid=24683020|pmc=7173716 }}</ref>
