Vasectomy reversal is usually
an outpatient procedure (without an overnight stay in the hospital).
Spinal or general anesthesia is commonly used to
ensure that you stay completely still during the surgery.

chances of vasectomy reversal success depend on how much time has passed
between the vasectomy and the reversal. Over time, additional blockages can
form, and some men develop
antibodies to their own sperm.

surgery is more complicated and takes more time when blockage between the vas
deferens and the
requires correction

What To Expect After Surgery

Vasectomy reversal usually takes from
2 to 4 hours, followed by a few more hours for recovery from the anesthetic.

What To Think About

Before a vasectomy reversal is
done, your doctor will want to confirm that you were fertile before your

You can have tests to see whether you have sperm
antibodies in your semen before and after vasectomy reversal. If there are
sperm antibodies in your semen after surgery, your partner is unlikely to
become pregnant. In such a case, you may wish to try
in vitro fertilization with
intracytoplasmic sperm injection.
