Vasectomy

 

Definition

A vasectomy is a surgical procedure performed on males in which the vas deferens (tubes that carry sperm from the testicles to the seminal vesicles) are cut, tied, cauterized (burned or seared) or otherwise interrupted. The semen no longer contains sperm after the tubes are cut, so conception cannot occur. The testicles continue to produce sperm, but they die and are absorbed by the body.

Purpose

The purpose of this operation is to provide reliable contraception. Research indicates that the level of effectiveness is 99.6%. Vasectomy is the most reliable method of contraception.

Description

Vasectomies are often performed in the doctor's office using a local anesthesia. The patient's scrotum area will be shaved and cleaned with an antiseptic solution to reduce the chance of infection. A small incision is made into the scrotum (the sac containing the testicles that produce the sperm). Each of the vas deferens (one from each testicle) is tied in two places with nonabsorbable (permanent) sutures and the tube is severed between the ties. The ends may be cauterized (burned or seared) to decrease the chance that they will leak or grow back together.
Sterility does not occur immediately after the procedure is finished. Men must use other methods of contraception until two consecutive semen analyses confirm that there are no sperm present in the semen. This will take four to six weeks or 15-20 ejaculations to clear all of the sperm from the tubes.
"No scalpel" vasectomies are gaining popularity. Instead of an incision, a small puncture is made into the scrotum. The vas deferens are cut and sealed in a manner similar to that described above. No stitches are necessary and the patient has less pain. Other advantages include less damage to the tissues, less bleeding, less risk of infection, and less discomfort after the procedure.
In some, cases vasectomies may be reversed. However, this procedure should be considered permanent as there is no guarantee of successful reversal.

Preparation

No special physical preparation is required. 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 possible risks and side effects. 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.

Aftercare

Following the surgery, ice packs are often applied to scrotum to decrease pain and swelling. A dressing (or athletic supporter) which supports the scrotum can also reduce pain. Mild over-the-counter pain medication such as aspirin or acetaminophen (Tylenol) should be able to control any discomfort. Activities may be

restricted for one or two days, and sexual intercourse for three to four days.

Risks

There are very few risks associated with vasectomy other than infection, bruising, epididymitis (inflammation of the tube that carries the sperm from the testicle to the penis), and sperm granulomas (collection of fluid that leaks from a poorly sealed or tied vas deferens). These are easily treated if they do occur. Patients do not experience difficulty achieving an erection, maintaining an erection, or ejaculating. There is no decrease in the production of the male hormone (testosterone), and sex drive and ability are not altered. Vasectomy is safer and less expensive than tubal ligation (sterilization of a female by cutting the fallopian tube to prevent conception).

Normal results

Normally, vasectomies are 99% successful in preventing conception. As such, it is one of the most effective methods available to consumers.

Key terms

Ejaculation — The act of expelling the sperm through the penis during orgasm.
Epididymitis — Inflammation of the small tube that rests on top of the testicle and is part of the system that carries sperm from the testicle to the penis. The condition can be successfully treated with antibiotics if necessary.
Scrotum — The sac which contains the testicles.
Sperm granuloma — A collection of fluid that leaks from an improperly sealed or tied vas deferens. They usually disappear on their own, but can be drained if necessary.
Testicles — The two egg-shaped organs found in the scrotum that produce sperm.
Tubal ligation — A surgical procedure in which the fallopian tubes are tied in two places and cut between. This prevents eggs from moving from the ovary to the uterus.

Etymology: L, vas + Gk, ektomē, excision
a procedure for male sterilization involving the bilateral surgical removal of a part of the vas deferens. Vasectomy is most commonly performed at an outpatient surgery center with local anesthesia. The procedure is also performed routinely before removal of the prostate gland to prevent inflammation of the testes and epididymides. Potency is not affected.

VASECTOMY AND ITS REVERSAL
Removal of all or a segment of the vas deferens. Bilateral vasectomy is the most successful method of male contraception. The procedure prevents sperm (which are manufactured in the testicles) from being expelled in the male ejaculate. It is usually carried out as an outpatient or same day procedure under local or light intravenous anesthesia. See: illustration

Note

Persons who have had this surgical procedure ejaculate in a normal manner but the ejaculate contains semen, produced independently in the seminal vesicles, without sperm.

Patient care

Postoperatively, the patient applies cold packs to the surgical site, to limit swelling, pain, and inflammation. Activities are limited, and sexual interest is avoided for the first week, approximately. An athletic supporter or tightly fitting underwear are worn to support the scrotum and limit pain. The procedure is considered successful when two consecutive sperm samples are shown to be free of sperm, typically 8 to 12 weeks postoperatively. Men choose vasectomy only when they want to become permanently sterile. Nonetheless, the procedure can be reversed, although vasectomy reversal is a more complicated operation than the initial severing of the tubes.

CAUTION!

Patients should be advised that vasectomy does not prevent sexually transmitted diseases.

vasectomy

The common operation for male sterilization. The VAS DEFERENS is exposed on each side through a short incision, just below the root of the penis, and is cut through and the ends tied off and secured well apart. Following this no newly produced spermatozoa can reach the exterior. The operation can be reversed but fertility is not always restored.

vasectomy

a minor surgical operation, involving the cutting and separation of the cut ends of the VAS DEFERENS so that they cannot rejoin. Effectively, the operation prevents the sperm from mingling with the secretions of the accessory glands and thus acts as a means of BIRTH CONTROL. The resulting semen, therefore, lacks sperm, and although a normal ejaculation can be produced, there is no risk of fertilization. Sperm is reabsorbed in the vas deferens and there is usually no effect on sexual behaviour.

vasectomy

excision of the vas (ductus) deferens, or a portion of it; bilateral vasectomy results in sterility.
