The tubes are cut, and the upper end (leading to the penis) is cauterized, or closed, and tucked back into its sheath (using a tiny titanium hemoclip), while the other end (testicular) is left open. This refers to the Open-Ended vasectomy. This open lower end will serve as an outlet for the sperm to exit. This will minimize the accumulation of sperm in the lower end of the divided vas deferens, and reduce the level of post-vasectomy discomfort.
In comparison to some of the more conventional vasectomy methods, this type of vasectomy combines the most effective technique with the lowest risk of complications, the quickest recovery time and the least amount of pain.
