Reaching the Vas: No-Scalpel Vasectomy
No-scalpel vasectomy is the recommended technique for reaching each of the 2 tubes in the scrotum (vas deferens) that carries sperm to the penis. It is becoming the standard around the world.
Differences from conventional procedure using incisions:
Both no-scalpel and conventional incision procedures are quick, safe, and effective.
Blocking the Vas
For most vasectomies ligation and excision is used. This entails cutting and removing a short piece of each tube and then tying both remaining cut ends of the vas. This procedure has a low failure rate. Applying heat or electricity to the ends of each vas (cauterizing) has an even lower failure rate than ligation and excision. The chances that vasectomy will fail can be reduced further by enclosing a cut end of the vas, after the ends have been tied or cauterized, in the thin layer of tissue that surrounds the vas (fascial interposition). If training and equipment are available, cautery and/or fascial interposition are recommended. Blocking the vas with clips is not recommended because of higher pregnancy rates.
