Men with a previous history of having a vasectomy may be candidates for a vasectomy reversal. This procedure involves reconnecting the ends of the vas deferens; which is the tube that carries sperm from the testis and epididymis to the outside during an ejaculation. The vas deferens is cut and tied during a vasectomy procedure.
The vasectomy reversal can be affected by the length of time that has passed since the vasectomy was performed. Vasectomy reversals are more successful the closer they are performed to the actual time of the vasectomy. A vasectomy reversal performed in less than 10 years from the original procedure would have a 60-80% chance of success if there are not other factors affecting fertility. This estimate can drop to 10 to 40% if the vasectomy was performed more than 10 years ago. The main reasons for the decline in fertility is related to a vasectomy reversal are from obstruction of the epididymis and from antisperm antibodies. Obstruction of the epididymis can usually be identified and corrected at the time of surgery. This is an important reason to use a skilled and experienced surgeon if you are considering this option. If this is not properly corrected, the pregnancy rates can drop as low as 10%.
