A semen analysis does not assess sperm
function. It dcoes not answer the question “ar the sperm good
enough to conceive”. More sophisticated tests of sperm quality
such as the Sperm Chromatin Structure Assay (SCSA) can better help
asses the “health” of the sperm.
The normal semen parameters established by the World Health Organization
are:
|
1.5-5.0 ml |
|
>20 million sperm/ml |
|
>50% |
|
>30% normal forms |
|
(scale 1-4) 2+ |
- Viscosity No Hyperviscosity

Collection Instructions
The semen sample should be collected at the laboratory in a special
sterile container after a 2-3 day period of abstinence from ejaculation.
Alternatively, the sample may be brought in from home within 1 hour
of ejaculation. The sample should be maintained at body
temperature which can easily be done by placing the container in
a shirt pocket. No lubrication should be used while obtaining the
sample as it can be toxic to sperm. Occasionally, due to religious
reasons, the sample may have to be obtained during intercourse.
A special condom designed for this purpose will be provided.
A minimum of two semen analyses provided several weeks apart, and
collected in a similar manner, is recommended because sperm counts
tend to fluctuate. We never rely solely on one sperm count.
