You've probably seen a least several commercials or print advertisements for birth control. It is one of those things that a sexually active woman has to deal with on a regular basis. While some women welcome the opportunity to become pregnant, others don't, so some of them initially undergo a surgical procedure to block their fallopian tubes.

Some of these women might have a change of heart down the line, and thus will elect to have tubal reversal surgery. However, before the topic of tubal reversal can be considered, the initial procedure in which the fallopian tubes are blocked should be discussed.

The actual conception process happens when the sperm fertilizes the egg – this much everyone knows. But, in order for an egg to be released in the first place, it has to be released from the fallopian tubes and into the uterus.

A woman's menstruation cycle happens when an egg is released from the fallopian tubes, is unfertilized, and becomes expelled by the body. When the fallopian tubes are blocked, an egg cannot be released, and the sperm cannot reach the egg. The reasons why women choose to have the initial procedure to block the fallopian tubes varies. However, it is usually because they are not at a point in their lives emotionally or financially where they want the added stress of having a child.

But then, things change. The woman might be at a point in her career where she feels financially secure. Or, she might be happily married to a guy that she knows will make an excellent father. Whatever the reason, she feels that the time is right to become a mother, and thus elects to have the tubal reversal procedure done.

In a tubal reversal procedure, the woman's fallopian tubes are unblocked (in the first procedure, there is usually a material that is placed within the tubes to block them from functioning to their full fertile potential). Thus, a woman will begin menstruating again, and be able to conceive.

Of course, this is only an example of the best case scenario. When a woman first gets her fallopian tubes blocked, she has to agree to the fact that there is a chance that the process might not be able to be undone. If a woman suddenly decides in her forties that she wants to have children, she is generally out of luck because of the extra risks involved.

However, if the woman is in her late twenties and early thirties, the chances of her having a successful outcome are much better. Before any of this can happen, however, she will need to find an excellent, certified, surgeon. Ideally, the surgeon should be a specialist in this area. When selecting the surgeon, it is important to review the success the surgeon has had with other patients. What the woman will need to look for is the amount of successful pregnancies that have occurred (obviously, the higher the better) after this surgeon has done the procedure.
