If a man decides to undergo permanent sterilization by vasectomy, family planning is usually complete. But life sometimes has other plans and so in 6-10% of vasectomized cases the desire to have children is revived. A so-called vaso-vasostomy can be an interesting option here.
Microsurgery is used to connect the vas deferens under a microscope
A vaso-vasostomy is a surgical refertilization method that can make natural conception possible again. In this microsurgical operation, the vas deferens that were previously severed by a vasectomy are reconnected. In a vaso-vasostomy, the two ends of the vas deferens are carefully sutured together again. A special microsurgical technique is used for this. The two sperm ducts (ductus deferens) are delicate tubes 3-4 mm in diameter. The threads used to sew them together are finer than a fifth of a human hair. The microsurgical procedure is performed under a microscope so that everything can be reassembled in a functional manner. After 2-3 hours under general anesthesia, the outpatient operation is usually over.
A success rate of 85-95%
A vasectomy should be considered a final decision when it is performed. However, if life plans change, there is a good chance that sterilization can be reversed. 85-95% of patients have a functional seminal flow again after the procedure. In general, the shorter the time since the vasectomy, the higher the chances of success. Approximately 50% of couples become pregnant after refertilization. Fertility not only depends on intact sperm ducts, but is also determined by a variety of factors. Fertile sperm and the fertility of the partner are also decisive for pregnancy and should also be taken into account.
Who is the vaso-vasostomy suitable for?
Refertilization cannot be performed on all men. If there is severe scarring in the area of the vas deferens or anatomical changes that make reconstruction considerably more difficult, the procedure cannot be performed. If the vasectomy was performed some time ago, it may be more difficult to perform a vaso-vaso. In general, men considering sterilization by vasectomy should accept infertility as the final, irreversible result.
How much does the vaso-vasostomy cost?
The vaso-vasostomy is not covered by health insurance. The patient pays between CHF 7,500 and 8,500 for the procedure. The operation is performed on an outpatient basis.
