Confirming Sterility |

Since you are not sterile after your vasectomy, temporary male
birth control is needed. At least 2 and sometimes more semen analyses are needed
to confirm no moving sperm are present. Testing typically takes place at two
months and then three months after your vasectomy procedure. If the 3 month test
shows no sperm then the patient is cleared to return to have unprotected intercourse.
You will be given a lab sheet to present to the lab with your semen sample
produced at home within the previous hour.
These tests are very important!

Concerns
About Dead Sperm & Sperm Passing Through Vas |
|
Studies show that there is no increased risk of having a
pregnancy with 3 readings of dead sperm on 3 consecutive sperm test when
compared to readings of no sperm at all. We know that some men with no sperm on
1 test later show dead sperm and vice versa so it is not a consistently reliable
in its absolute terms.
The chance of a sperm passing through the blockage in the sperm tubes is
extremely small - especially once the sperm tubes are cut, cauterized and then
separated by the fascial sheath barrier. But failure is possible.

Vasectomy Failure Rates |
|
The incidence of vasectomy failure is estimated between .5% and 1% and varies with the skill and experience of the doctor and with the approach used to block the tubes. It is for this reason that testing semen samples is essential.
You can inquire about the success and complication rates of the vasectomy doctors you interview.
If, in the unlikely event that repeated semen checks show persistent live moving sperm, your vasectomy will have to be repeated.
