What is a semen analysis?
A semen analysis evaluates the seminal characteristics
of the ejaculate, in order to assess whether there are any deficiencies
that may impair fertilization and subsequent pregnancy. The various parameters
tested are:
- Semen volume
- Sperm concentration
- Sperm count
- Percentage motile sperm
- Grade of motility
- Normal sperm morphology
These parameters allow us to detect if there are any problems
with the reproductive system, so that you and your physician may isolate
the problem and treat it efficiently and effectively.
Who needs to have a semen analysis?
Anyone who is having trouble conceiving should have a semen analysis
done. In about 40% of infertile couples, the cause of the infertility
lies with the males, and this could easily and quickly be diagnosed via
a semen analysis.
Where can I have my semen analysis
done?
There are many centers and labaratories, even on the web,
that offer semen analysis. However, please note that many centers do
not perform a comprehensive analysis, leaving out some key tests or parameters
that could be crucial in determining the proper and accurate diagnosis
of a patient's problem or difficulty. Those labs or facilities that offer
semen analysis services over the Internet lack the necessary semen shipper
and complete understanding of all principles involved to offer you, the
patient, the types of answers that you are looking for. The BioTranz
semen shipper is the one and only proven product and technology of its
kind.
The Andrology Institute
of America (AIA) is an internationally
recognized center that deals specifically with the evaluation of male
infertility. The AIA performs a detailed analysis and together with the
patient history, will make certain recommendations to you and your physician
with regards to your treatment.
Also, the laboratory facilities at AIA
are CLIA certified by the U.S. Department of Health (CLIA, 88).
How should I collect the sample?
We prefer that the sample be collected during intercourse
via the use of the Zavos Seminal Collection Device (ZSCD™), a non-spermicidal condom
that has been shown to yield better results than collection via masturbation.
The seminal collection condoms are avialable from the Andrology Institute.
If needed, the sample may be collected via masturbation or coitus interruptus,
but these methods are not recommended.
What about sexual abstinence?
The sample should be collected after 3-4 days of sexual
abstinence. It has been shown that shorter abstinence periods may result
in lower sperm counts but possibly higher quality sperm whereas longer
periods may yield lower percentage of motile sperm and overall poor
quality sperm.
What are the normal values for
a semen analysis?
Normal semen values as outlined by the World Health
Organization are as follows:
| PARAMETER |
MINIMUM VALUE |
| Volume (mL) |
2.0 |
| Sperm Concentration (million/mL) |
20 |
| Motility (%) |
50 |
| Forward Progression (0-4) |
3 |
| Normal Morphology (%) (WHO) |
30 |
| Normal Morphology (%) (Strict) |
14 |
| Total Sperm Count (million) |
40 |
| Total Motile Sperm (million) |
20 |
| Total Functional Sperm (million) |
