Vasoepididymostomy connects the end of the vas deferens tube on each side of the scrotum directly to the epididymis on the same side.
Vasoepididymostomy is done when an obstruction in the vas deferens close to the epididymis, or in the epididymis itself, is stopping sperm from getting through.
Vasovasotomy tends to have better success rates than vasoepididymostomy.
After vasoepididymostomy, the chance of a couple getting pregnant ranges from about 11% to 56%.
If the first surgery left the vas deferens very short, or if there appears to be scar tissue near the epididymis, the second attempt may be the more complicated vasoepididymostomy.
