VasoepididymostomyA vasoepididymostomy is either performed in cases of blockage to the epididymis (sperm reservoir) or in some instances when a vasovasostomy (vasectomy reversal) is not possible.

In these cases, dye is injected (a vasogram) to ensure that there is no blockage further into the abdomen and if the situation is amenable to reconstruction, a microscope is used to perform a vasoepididymostomy by using very fine stitches.

This is performed under an operative microscope using very fine suture material and the procedure can take up to four hours.
