Semen Analysis
Definition - What does Semen Analysis mean?
A semen analysis refers to the laboratory testing of semen to assess fertility, either for the purpose of fathering a child or after a vasectomy to insure that the semen no longer contains sperm. This is the analysis will most commonly include a count of:
- Sperm concentration (number)
- Motility (the ability to move straight quickly)
- Morphology (shape)
The fluid surrounding the sperm may be tested for:
- Volume of semen
- Seminal fructose concentration (can indicate a blockage or obstruction)
- pH,
- the presence of white blood cells (which would indicate infection) and the
- Liquefaction - time required for the fluid to transform from a gel to a liquid.
A semen analysis is can detect male fertility problems and accurate diagnosis may improve fertility if it leads to effective treatment.
FertilitySmarts explains Semen Analysis
Either at home or a lab, a semen sample is obtained by masturbating into a specimen cup. It is generally suggested to refrain from ejaculation for a period of two to three days prior to the test in order to produce an ideal sample. Long periods of abstinence may produce a sample where sperm demonstrate lower motility (movement).
