Post VAS Semen Analysis, AUA

Test ID: 


CPT code:



•Postvasectomy Semen Analysis

Clinical Use:

Azoöspermia and <0.1×106 nonmotile sperm per mL (or <100,000 nonmotile sperm per mL) are reliable indicators of vasectomy success.

Incomplete ejaculation and/or incomplete collection of total ejaculate may cause false oligospermia (low sperm count) or false azoöspermia.

If >0.1×106 nonmotile sperm per mL (or >100,000 nonmotile sperm/mL) persist beyond six months after vasectomy, then trends of serial postvasectomy semen analyses and clinical judgment should be used to decide whether the vasectomy is a failure and whether repeat vasectomy should be considered.

Specimen Type:


Requested Volume: 

0.5 mL Entire ejaculate

Container Type: 

Sterile screw-cap container

Patient Preparation: 

No special preparation. The American Urological Association recommends a waiting period of 8 to 16 weeks post vasectomy as the appropriate period for the first post vasectomy semen analysis.


See Patient Instructions for Semen Collection.

Storage Instructions:

Testing must begin within 60 minutes of specimen production. In the interim, the specimen should be kept at room temperature, but it is recommended that it be kept close to the body (inside a shirt or coat) to avoid temperature extremes during transport.

Rejection Criteria:

Specimens older than one hour; specimens contaminated with spermicidal material.
