Vasovasostomy                                     (male refertilisation)

... or, put simply, restoring male fertility

Your family planning has changed and you would now like a child having had, however, a vasectomy in the past?

Almost every 10th man in Germany who has had a vasectomy would like it reversed.

Vasovasostomy is a process that, thanks to microsurgical techniques and modern suture materials, can restore the throughflow of the sperm ducts with a very high success rate.

If the ligaturing of the sperm ducts took place less than 10 years earlier, restoration of throughflow succeeds in almost 95% of cases. The pregnancy rate is about 70%. If the ligaturing of the sperm ducts took place more than 10 years earlier the success rate is still high (70%) but the pregnancy rate falls considerably – to about 45%.

What should you consider before the operation:


Before vasovasostomy both partners should generally be examined to check that there is nothing to prevent natural fertility.


The renewed connection of the sperm duct is an intervention that requires maximum skill and a lot of experience in operations. The suture material is so soft and thin that it can hardly be seen with the naked eye. Not every urological practice has the necessary technical equipment and expertise gained from hundreds of interventions. We have specialised in vasovasostomy, among other things, and have been treating patients from many European countries at our practice for over 20 years.

What can you expect during the operation?


In vasovasostomy two small cuts are made left and right above the skin covering the testes. This reveals the sperm ducts. The ends of the sperm ducts are prepared and tested for throughflow. Then the ends are reconnected with one another using a multilayer suturing process. The innermost suture connects the mucous membrane of the sperm ducts. This ensures that the sperm can flow again unhindered from the testicles towards the penis. Another suture level is used to give the sperm ducts support, and a third layer is mostly added to provide even greater stabilisation of the reconstructed sperm ducts.


The operation usually lasts two hours. It is carried out under full anaesthesia and is ambulant, i.e. the patient is not confined to bed.



After the operation

  • Showers after the 3rd day
  • Bathing and saunas after the 10th day
  • Sexual activity after 3 weeks
  • Sport and demanding physical effort after 4 weeks
