Vasectomy is one of the most effective methods of birth control available for men. The procedure entails the ligation of an important conduit for sperm cells known as the vas deferens. Once this has been done, the cells can no longer be transferred into the female genital tract for fertilization to take place. To reverse vasectomy, the continuity of these conduits has to be re-established using surgery.
A technique termed microsurgical vasectomy reversal is the most effective for use in this procedure. It involves minimal access of the anatomical structures of interest. A powerful microscope makes this possible. The main advantages of the technique include higher success rates and less complications. Reestablishment of fertility is achieved using one of two approaches; vasovasostomy (joining of the cut stumps) and vasoepididymostomy (joining the vas deferens to the epididymis).
While numerous improvements have been made on the techniques that are used, failure is not uncommon. One of the reasons as to why this is the case is the fact that the vas deferens is a very small tube that is greatly affected by scarring once ligation has been done. The scar tissue has to be removed before the two stumps are re-joined. The two stumps may be of different diameters which serves to reduce success rates as well.
Before undergoing the surgery, one has to be evaluated by their urologist. Part of the evaluation includes determining that indeed the subject was fertile before the ligation of their vas deferens. The next important thing at this stage is to find out if any sperm antibodies exist within the semen. If found, the probability of ending up with a pregnancy is next to nil and assisted reproductive options should be sought.
Research shows that success rates may be as high as 70% to 90%. Age, is not a major determinant of who succeeds and who does not. However, the duration of time that elapses from the date of ligation does influence fertility rates to a great extent. Generally, persons who undergo the procedure within three years of vasectomy have success rates in excess of 50% while those that have it after more than 10 years have a rate that is as low as 30%.
The microsurgical procedure is regarded as being generally safe but there are a number of complications that may be encountered albeit rarely. In the immediate post-operative period, the common complications include excessive bleeding, fluid accumulation within the scrotum (also known as hydrocele) and infections. Nerve fibers may also be injured. Rare complications include deep venous thrombosis and reaction to anesthesia.
The operation itself is usually done on an outpatient basis and typically lasts between two and four hours. Spinal anesthesia is typically used which means that one can be discharged from hospital on the same day. The resultant pain is mild and can permit resumption of normal routines within three days or thereabout.
Fertility is an issue that affects two people; the man and the woman. If pregnancy is not achieved, both should be investigated before a diagnosis of failure is made. Fertility problems should be suspected in woman who are above thirty five years who have failed to conceive in spite of engaging in regular sexual relationships with a fertile partner.
