Vasovasostomy is the surgical technique that aims to anastomosis or recanalize the vas deferens that have previously been sectioned by performing a vasectomy.
The intervention is performed under local anaesthesia and lasts approximately 3 hours. It is done on an outpatient basis.
- Surgeon’s experience in microsurgery
- Obstruction Time: That is, time elapsed since the vasectomy. The success rate (positive seminograms) according to the latest publications * / **, is:
- <5 years – 96%
- 5-10 years – 90%
- 10-15 years – 65%
- 15-20 years – 35%
Although the seminogram is positive, a pregnancy may not be achieved spontaneously, although it may simplify and make assisted reproductive techniques possible.
- Surgical technique: The use of microsurgical material and techniques is essential.
- Level of obstruction: Determined by where the vasectomy was performed. The further away from the testicle the better, because the diameter of the vas deferens is greater.
5-hour fast and shaving of the area.
Gentle movements the first 3 days and 20 days without practicing intercourse (to ensure healing of the suture of the vas deferens).
1st semen analysis at 8 weeks. If we observe the presence of motile sperm, a new control is carried out 16 weeks after surgery to observe the result of recanalization. If in the first control we observe azoospermia (absence of sperm), we perform a new analysis 16 weeks after surgery. If this fact persists until 32 weeks after the procedure, we consider that it has not been successful.
Obtaining sperm by puncture and biopsy of the testicle, and with the sperm obtained, practice an In Vitro Fertilization (IVF – ICSI).
