Type of Surgery
Information
Last updated: 02/17/2009
No special physical preparation is required for a vasectomy. The physician will first assess the patient's general health in order to identify any potential problems that could occur. The doctor will then explain the possible risks and side effects of the procedure. The patient is asked to sign a consent form which indicates that he understands the information he has received, and gives the doctor permission to perform the operation.

Vasectomy is a surgical procedure in which the vasa deferentia of a man are cut for the purpose of sterilization.
There are some variations on the procedure such as no-scalpel (keyhole) vasectomies, in which a sharp hemostat, rather than a scalpel, is used to puncture the scrotum. Another type of vasectomy which may reduce the risk of chronic pain is called an "open ended" vasectomy. A "normal" vasectomy typically seals both ends of the vas deferens with stitches, heat, metal clamps or a combination, after cutting. The open-ended vasectomy obstructs only the top end of the vas deferens. With this method sperm leaks out from the lower severed end of the vas deferens and into the scrotum, thus hopefully avoiding a build-up of pressure in the epididymis. The likelihood of long-term testicular pain from "backup pressure" seems to be reduced using this method.

It's a controversial arena -- the PSA is a marker of prostate bulk and size, but it's highly expressed in benign prostate disease as well as cancer -- so in that context it's not a specific marker.
