Vasectomy is a is a minor operation in which the two tubes that carry sperm from the testicles to the urinary tract are surgically altered so sperm cannot pass through.
This procedure takes no more than 30 minutes. The surgeon reaches the vas through one or two small cuts made in the front surface of the scrotum, after a local anesthetic makes the area numb. The doctor cuts the tubes and cut ends are tied or sealed with electric current.
After a vasectomy, a man still has erections and ejaculates, but there is no sperm in his ejaculations. Right after the operation there are always some active sperm left in the semen. It takes about 20 ejaculations to clear them. Patient semen will be examined under a microscope more or less 4-8 weeks after surgery to make certain that no sperm remain.
Complications with vasectomy are usually related to bleeding or infection.
