Vasectomy refers to permanent male sterilization, done by closing off the vas deferens. The vas deferens is the tube carrying sperm from the testes to the urinary tract. There is a vas deferens on each side, connected to each testis, which travels through the spermatic cord.
It is a safe and highly effective method of permanent sterilization that is minimally invasive. It has no effect on erections, ejaculation, or sexual enjoyment or function otherwise
Vasectomy can be done with local anesthesia (numbing medication injected into just the area where we operate), or under other anesthesia techniques (where the person is sedated or asleep), as an outpatient procedure.
The important thing to know is that it is not immediately effective and that protection during intercourse is still required until a sperm count showing zero sperm is obtained (usually checked 8 weeks after surgery).
