The doctor will choose to perform one of two methods to reconnect the vas - vasovasostomy or vasoepididymostomy. But
a definitive decision as to which reconnection will be required can only be made during the surgery based upon the presence of sperm and the quality of fluid from the vas. If sperm are identified from the cut end of the vas coming from the testicle and epididymus, this confirms that sperm are being produced and are able to swim to this point and a vasovasostomy can be performed. If no sperm are seen within the fluid from the cut-end of the testicular vas, this typically suggests an epididymal blockage and a bypass re-connection or vasoepididymostomy should be performed.
1. Vasovasostomy,
which is for the simpler cases, reconnects the two cut and blocked ends
of each vas deferens.

2. Vasoepididymostomy is performed for more complex
cases, connecting the vas deferens to the epididymis.

No matter how
long after a vasectomy, there is always a chance to obtain a successful result.
