A vasectomy should be considered a permanent form of birth control for men. It is a sterilization process achieved by interrupting the tubes that carry the sperm from the testes to the penis. This prevents sperm from being released in the semen during ejaculation. A vasectomy usually is done in the doctor's office in about twenty minutes under local anesthesia.  A small incision or puncture is made on  the scrotum and the tubes are isolated, cut and tied with sutures. The skin then is closed with a few small stitches if needed. There is some pain and bruising for a few days following the procedure, which can be reduced with ice packs after the procedure. 

Male sexual performance is not affected by this surgery, and sexual activity may resume as soon as discomfort subsides. It is important to remember that it can take up to six weeks to clear residual sperm from the tubes, so a reliable form of birth control should be used until no sperm are seen in the ejaculate.

Non scapel technique is very similar in that a small puncture is performed and the vas brought through the puncture wound.  The rest of the procedure is similar to the surgical technique.   It may have slightly less bruising, but otherwise similar complications.
