Surgery to recanalize the vas deferens and restore fertility in man is called vasovasostomy.

The causes and indications for a vasovasostomy in patients who have a vasectomy are:

  • Desire to have one or more children after the divorce and find a new partner
  • After the death of a child
  • By improving the family’s economic income

Benefits of performing the vasovasostomy

The objective of performing a vasovasostomy is to achieve the permeability of the vas deferens, so, one or more pregnancies can be achieved.

By permeabilizing the vas deferens can achieve a pregnancy in a physiological way through intercourse.

The vasovasoanastomosis is cheaper than some artificial reproduction techniques such as testicular sperm extraction (TESE) or intracytoplasmic sperm injection (ICSI).

The permeability rate after surgery is 80% and the pregnancy rate is 60%. If it has been more than 5 years after vasectomy, these rates decrease to 60% and 40% respectively.

Risks and complications

The possible complications that may occur when performing a vasovasostomy are the same that can occur in general with any surgical procedure and these are: hemorrhage, damage to nearby organs, reactions to anesthesia, etc. However, these complications occur infrequently and can be resolved mostly during the same surgery.

Alternatives to vasovasostomy

There are other options to achieve a pregnancy:

  • Artificial insemination
  • TESE
  • ICSI among others

All these are assisted reproduction techniques.

What to expect from the vasovasostomy?

Day of surgery:

The day of the operation will arrive in the morning to the hospital in fasting

The surgery takes approximately 3-4 hours to be done, however, the time is variable.

Anesthesia for this procedure is spinal block (in the back) and sedation so you will not feel pain and will be relaxed during the procedure.

The pain after surgery is minimal and can be effectively controlled with intravenous analgesics.

Food: on the day of surgery you can eat in the afternoon, there are no food restrictions, however, a balanced diet is recommended.

Physical activity: the day after surgery you can walk. It is expected to feel a bit fatigued after any surgery, this problem resolves spontaneously within a few weeks after the procedure.

Hospital stay: most patients operated of vasovasostomy remain hospitalized for 1 day.

Wounds: to perform a vasovasostomy, two incisions are made in the scrotum, each approximately 2 cm. Once these wounds are healed, it is difficult to see them.
