Vasectomy Reversal (Vasovasostomy)

Vasectomy reversal refers to a surgical procedure designed to restore fertility to men who have undergone a prior vasectomy sterilization procedure. Different techniques for vasectomy are performed, however, virtually all involve blockage of the vas defense tubes in the scrotum to prevent flow of sperm from the testicle into the urethra. Vasectomy reversal is a commonly inquired about procedure but is not appropriate for all men. Special considerations include the time since the vasectomy, the age of the man’s partner and other medical conditions that may interfere with the repair.

For men who are considered appropriate of the procedure, it is performed on an outpatient basis, can take anywhere from two to three hours and often requires the use of specialized instruments, including a microscope and in some cases a robotic surgical system. Incisions are made in the scrotum to gain access to the vas deferens.  The two ends of the previously divided vas deferens are identified and the two ends are connected using stitches that are very thinner than human hair.  A successful vasectomy reversal is defined as moving sperm in the ejaculate.  

Factors that can negatively impact a successful vasectomy reversal include: a long time since the vasectomy (generally considered greater than seven years) and older age of the man.  Reblockage of the vas deferens is a common complication of the procedure and in some studies is as high as 50% after one year.  For this reason, it is important that sperm be collected and frozen at the time of the vasectomy reversal and we offer that service at no additional charge from a surgical standpoint although additional fees for sperm storage will be incurred.

The procedure is usually an outpatient procedure performed under general anesthesia and lasts between two and five hours.

Successful Vasovasostomy is defined by the return of motile sperm to the semen in numbers that are adequate for pregnancy; success rates range between 30% and 85%. The longer the reversal is from the original vasectomy the lower the success rate. On occasion the procedure renders unsuccessful and must be repeated. Overall vasectomy reversal leads to pregnancy in about 50% of couples. After the procedure the vas deferens can get blocked again about 50% of the time after 1 year.

Possible Complications include:

• Bleeding within the scrotum.

• Infection at the surgery site.

• Damage to nerves and blood vessels, possibly hindering fertility.

• Blockage of the vas deferens occurs in 1/2 of patients after one year from the development of scar tissue.

• Blood clots in the legs (deep vein thrombosis).

Please observe the following Pre-Operative Guidelines:

• The following medications should be Avoided One Week Prior to the Date of Surgery: All aspirin (ASA) or NSAID’s (Motrin, Advil), Coumadin, Lovenox, Celebrex, Plavix (Please contact us if you are unsure about which medications to stop, Do not stop any medication without contacting your prescribing doctor).

• Have nothing by mouth after midnight the night prior to your procedure unless otherwise instructed by the anesthesiologist.

• There are no restrictions on sexual activity prior to surgery.
