Vasectomy is a permanent surgical contraceptive method that consists of blocking the vas deferens (channels that transport the semen) of the male reproductive system so that the passage of sperm from the testicles to the urethra is interrupted. This procedure is considered irreversible.
On some occasions, vasectomized men wish to have children again, for which they can resort to various treatments:
Vasovasostomy. Intervention to recanalise the vas deferens and allow sperm to pass back into the urethra. It is a complex procedure and the result will depend on the way the vasectomy was done, as well as the time that has passed since it was performed. Its success rate is much lower than the success rate with an in vitro fertilization treatment. It has the disadvantage that once pregnancy has been achieved, the patient must undergo another vasectomy if he does not wish to have any more offspring.
In vitro fertilization (IVF) with sperm obtained from testicular biopsy or epididymis aspiration
Sperm donation for artificial insemination (AI) or IVF depending on the characteristics of the woman.
