Semen analysis is the first diagnostic test that is used to assess a man’s fertility.
WHAT PARAMETERS DOES A SEMEN ANALYSIS EVALUATE?
Ejaculate volume > 1.4ml
Total number of sperm in the ejaculate > 39 million
Total sperm motility > 42% o r> 25% actively motile sperm
Immotile sperm up to 20%
Vitality (live sperm) > 54%
Morphology (normally shaped sperm) > 4%
The World Health Organization (WHO) reference values and the Kruger criteriа for morphology are used to determine the examination’s conclusion.
MOST COMMON DIAGNOSES
You may come across one of these terms as the conclusion of your semen analysis:
Normozoospermia – normal semen analysis
Oligozoospermia – reduced sperm count
Asthenozoospermia – reduced sperm motility
Teratozoospermia – deteriorated morphology of sperm
Azoospermia – lack of sperm in the ejaculate
SHOULD I PREPARE FOR THE EXAMINATION?
Sexual abstinence is required within 2-5 days before the test. In addition, severe mental or physical stress as well as high temperatures (sauna, hot shower or bath) should be avoided. This ensures the maximum concentration of sperm and the results are the most objective.
COMPUTER-ASSISTED SPERM ANALYSIS
New Life Specialized Medical Center for Gynecology has a Computer Assisted Sperm Analyzer (CASA). This is an automated system for sperm analysis, in which the concentration, motility and morphology of sperm is assessed by specialized software, unlike a regular semen analysis, in which these parameters are assessed by a biologist. The main advantage of semen analysis by CASA is that it eliminates the subjectivity associated with the human factor, which allows better standardization of the test.
The results are usually ready within 1 day. Abnormal results are not necessarily a diagnosis. Sometimes this is a temporary condition due to external factors. In these cases, a repeat semen analysis is performed after a certain period of time.
