The deferens is the conduct through which spermatozoids move from the testicle to the urethra. In a vasectomy, it is the tube that we section to avoid pregnancies.

Vasovasostomy consists of the union of the deferens segments that have been sectioned and plugged in a vasectomy. The surgery aims to create a free access for spermatozoids to achieve a pregnancy with sexual relations.


Vasovasostomy is a delicate surgery that requires large experience and expertise to achieve the best results. The intervention lasts from 2 to 3 hours and it is usually performed with long-lasting local anaesthesia.

The vasovasostomy success will depend on numerous factors: vasectomy technique performed in the past, vasovasostomy method, time elapsed since the vasectomy, patient’s age, etc.


The patient will be able to return to work within 3 days to a week after surgery, depending on the physical complaints. These may last up to 3 weeks. Therefore, it is recommended not to make physical efforts neither practise any sport in the first three weeks. It is possible to engage sexual activity 15 days after surgery. .

Although it is not easy to predict when a pregnancy will be achieved, if surgery is performed without complications and the post-operatory is good, in some cases a pregnancy was achieved 3 months after the intervention. However, some patients need up to 2 years to get an average spermiogram (semen analysis). Sometimes patients presenting an average spermiogram face a deferens obstruction again. In some cases, it is possible to perform another surgery. According to published studies, over 40% of these “second-try” interventions are successful.
