During the tubal ligation procedure, the fallopian tubes are cut and sealed off. The fallopian tubes are pathways between a woman's ovaries and uterus, and an egg travels along them every month during menstruation. Tubal ligation blocks this pathway so that the egg cannot travel to the uterus, and cannot meet with any sperm. If sperm and egg cannot come together, the egg cannot be fertilized, making pregnancy impossible

Tubal ligations are often performed at the same time as the birth of a child. It can be done to women who are not pregnant, however. In these cases, the woman’s abdomen is inflated with gas, to improve access to the fallopian tubes, and a thin instrument called a laproscope is inserted through a tiny incision in the navel area to perform the operation.

There are several methods for blocking the fallopian tubes during the operation. The tubes can be fused using an electrical device; they can be stitched and tied off; or they can be sealed with plastic clips or rings. The doctor may remove a small section of each tube in addition to one of these methods.
Tubal ligations take about one hour to perform, and are usually performed as outpatient procedures. Most patients go home the same day.

Clips and Bands
This method is usually very easy to reverse. It leaves the fallopian tubes intact and makes the reversal procedure relatively simple.

Pomeroy
During this surgical technique, the fallopian tubes are “strangled” using a suture.  The tube is typically cut and the ends cauterized.  Despite cauterization, this procedure is usually reversible.

Irving or Uchida
This method is also reversible.  In this method, the fallopian tube near the uterus is folded over and buried in tissue.  This method of tubal ligation is the most unlikely to fail, and is generally reversible. 

Parkland
This method is similar to the Pomeroy; a portion of the tube is removed and the tube is tied off with a suture.  If only a small section of the fallopian tube has been removed in the original procedure, it is possible to reverse.  

It is sometimes possible to reverse a tubal ligation. However, the reversal operation is much more invasive and complex than the original procedure, and the success rate is only 60-80%. In addition, there is a heightened risk of ectopic pregnancies—where the fetus develops outside the uterus—for those women who are able to conceive after the reversal. Because of the increased risks involved with pregnancies after the reversal, as well as the chance of failure, those considering this operation must be absolutely sure they will not want it reversed.

Many women who have had a tubal ligation procedure often undergo in vitro fertilization (IVF), rather than a reversal procedure, if they find they want to get pregnant. In vitro fertilization (IVF) is often considered a better option for women who wish to get pregnant after a tubal ligation than reversal surgery. During IVF, a mature egg is taken from the woman's ovaries and fertilized with sperm in a laboratory. The egg is then injected back into the woman's uterus, where it develops. This is not an easy option, however; it is very costly, and as with tubal ligation reversal, it is not universally successful.

Tubal ligation is the most effective during the first year after the procedure. The chance of pregnancy during that time is less than 1%. Over a longer period of time, some women’s fallopian tubes may fuse together again, which makes it possible for them to become pregnant. This is particularly likely for women who get the procedure done while they are younger and still in their reproductive prime.

For women in monogamous relationships who wish to limit their pregnancies, a vasectomy is often a better option for the couple than a tubal ligation. Vasectomies are safer, simpler procedures with fewer risks and complications. They are also believed to be more effective at preventing pregnancy than tubal ligations. They are, however, not effective immediately, as tubal ligations are. During a vasectomy, a small incision is made in the man's scrotum, and the two tubes that bring sperm from the testicles are cut and tied off.

Most tubal ligation patients experience pain and soreness in the abdominal area, for which they may need pain medication. Other aftereffects include fatigue, dizziness, bloating, and nausea. Patients who have undergone a laprascopic procedure during the course of surgery can experience discomfort in the shoulder or neck area. This is a common side effect of the gas used during the procedure, which can irritate the diaphragm. Most women are recovered enough to move around, eat normal food, and care for their babies if the procedure was undergone in conjunction with giving birth. Most women who do not give birth will be home and living normally within a few days.

It is important to remember that women who have had tubal ligations still need to have Pap tests performed regularly to screen for health problems. If you do not know how often you should have a Pap test done, consult your doctor

No. Tubal ligation does nothing to prevent sexually transmitted diseases

Not difficult at all. Tubal ligation is a common method of birth control. The best thing to do is talk to your doctor, who will be able to discuss whether tubal ligation is the best option for you, as well as help you with a referral.

Like all other kinds of birth control, there are pros and cons to tubal ligation. Consider these thoroughly before you make your decision.

Pros

• Tubal ligation is a permanent form of birth control.
• There are minimal side effects.
• Tubal ligation does not affect sexual desire.
• It provides safe, dependable protection for women who could have health complications during pregnancy.

Cons

• There are minor risks involved, as with all minor surgeries involving anesthesia.
• Discomfort is possible during the recovery period.
• It does not protect against STD's.
• It is very difficult to reverse
