What is a vasectomy?
A vasectomy is a minor surgical procedure designed to interrupt the sperm transportation system between the testicle and the urethra by blocking the vasa deferentia.
How is a vasectomy performed?
In general, vasectomies are performed in the urologists office. However, the procedure may be done at an ambulatory surgery center or in a hospital setting if the patient and urologist have determined that intravenus sedation is preferable. The decision to proceed in that type of setting may be based upon the patients anatomy, anxiety or the need for associated surgical procedures.
The effectiveness of the vasectomy must be proven by having the patient submit at least one semen anlisys , which demonstrates that there are no sperm in the ejaculate. The time until disappearance of sperm from the ejaculate varies from patient to patient. Most urologists do not recommend checking the semen for sperm for at least three months or 20 ejaculates, whichever comes first. If sperm continue to be present in the ejaculate, that patient must continue to use contraception.
