Microsurgical Epididymovasostomy (Advanced Vasectomy Reversal)
If sperm are not found in the testicular end of the vas deferens at the time of surgery, an obstruction has likely occurred further upstream of the vasectomy site. Thus, the more complex Epididymovasostomy procedure may necessary. This procedure involves reconnecting the vas deferens directly to the epididymis.
The entire procedure is performed under a special microscope. If it is necessary for me to perform an Epididymovasostomy on both sides, success rates are 50-60% because the tubes of the epididymis are one-fifth the size of the vas deferens. Most surgeons will recommend sperm cryopreservation (freezing of the sperm) for backup at the time of the vasectomy reversal, especially if a bilateral epididymovasostomy is performed.
