Vasovasostomy is a microsurgical treatment that consists of reopening the passage of sperm through a different duct than the one that was interrupted in the vasectomy.
Is it a frequently performed treatment?
In our center, about three patients a month come to consult us for vasovasostomy. We believe that this is due to the fact that many patients, and even some doctors, are unaware that this treatment exists and believe that the only solution to vasectomy is to resort to assisted reproductive techniques such as in vitro fertilization.
However, it should be noted that vasectomy reversal has better results and lower cost.
Is vasectomy reversible in all cases?
In most patients it is reversible. In our center we have results of presence of spermatozoa in semen after the operation of 91%.
In addition, to increase the guarantees of success and to face the remaining 9% of cases, we have the possibility of freezing testicular tissue with spermatozoa.
How long does it take to take effect?
If we find normal sperm after the operation, the male part of the problem disappears automatically. Therefore, if pregnancy is not achieved within a year, it is recommended that the woman attends a gynecological consultation.
In cases of low sperm count, after 6 months these sperm are recovered for insemination or other assisted reproduction techniques.
In case of failure to obtain sperm, it is indicated to proceed directly to assisted reproductive techniques or in vitro fertilization with frozen sperm.
Is vasovasostomy risky?
With respect to life, this procedure has a very low or non-existent risk. In our experience for more than 30 years the vital risk is zero. If sedation is added to the local anesthesia, the risk increases in relation to possible substance sensitivity effects.
Other side effects of the treatment are wound infection, which in our experience is less than 4 patients per thousand. In addition, hematoma or blood accumulation may occur in less than 3% of cases.
