Traditional vasectomy involves a scalpel cut into the scrotum (sac
that holds the testicles) after a local anesthetic has been used to
"numb" the sac and the two vas deferens (sperm transport tubes).
Each vas deferens tube is cut, a section is removed, and both sides
of the cut vas are sealed with either sutures, cautery or metal
clips. This interrupts the flow of sperm from the testicles into the
ejaculate which is also called semen. The incisions are then closed
with sutures.
Open-end vasectomy is a variation on the traditional technique, in
which the cut end of the vas on the testicle side is left open
without sealing it shut. Some doctors feel that this creates a more
reversible vasectomy, which could be important for those who think
they may some day be concerned with vasectomy reversal success.
No-Scalpel Vasectomy (NSV) was developed in China in the mid 1970's.
The technique uses two special non-traumatic instruments to provide
a quicker, safer and less tender procedure than the traditional
vasectomy. It was first performed in the United States in the
1980's. Dr. Buch has used the NSV procedure since 1993, and he is an
NSV patient himself.
