Laboratory assay overview
Complete absence of sperm in this test is considered a negative result. Incomplete ejaculation and/or incomplete collection of total ejaculate may cause false-negative results.

Laboratory assay overview
Azoöspermia and <0.1x106 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 >0.1x106 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.

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
