In many infertility cases, half of the problems are because of male infertility. In order to determine the infertility level in males, it is essential to get an accurate assessment of the count and magnitude of healthy sperms. Detailed and quick linear sperm motility is presently the accurate predictor of the sperm performance.
By using the latest computer system to perform the semen analysis, more accurate results can be received than manual analysis.
What does CASA stand for?
CASA (Computer Assisted Semen Analysis) is an automated technique to evaluate the video images of sperms by using a strong microscope to find the motility level of each sperm among the population. It is a highly advanced SEMEN analysis technique that generates more accurate results and is superior than manual analysis of SEME motility.
CASA’s accuracy allows the Andrologists to evaluate the diverse characteristics of sperm movement such as its speed, linearity and amplitude of lateral head displacement. This test is a crucial step in suitably treating the male factor infertility. It enables the surgeons to receive highly accurate and consistent lab results. CASA has become the premier and advanced male factor infertility treatment in the present time.
Significance of automated CASA
The manual microscopic semen study results in the vast quality and accuracy difference in center to center and needs extensive efforts to control the quality and maintain the standards. It becomes a heftily time consuming and low yield process which puts a question mark on the truthfulness of the reports.
On the other hand, computer assisted semen analysis allows a comprehensive analysis of the various factors such as sperm’s movement, health level, VCL (Curvilinear velocity), VSL (straight line velocity), VAP (path velocity) and ALH (amplitude of lateral head displacement).
Benefits of CASA
CASA is extremely significant in terms of its various qualitative approaches, few of them are:
• Greater reliability in determining the fertility level
• Accuracy that is hard to receive through semen analysis
• The test outcomes are more objective because of the standardization of testing conditions
• Motility factors in CASA reports are of wide significance in infertility evaluation in comparison with the outcomes of standard semen analysis.
How CASA technique works
CASA is extremely worthy in determining the cause of male infertility. The foremost advantage of this latest method is to accurately determine the sperm concentration and motility that is generally performed by processed digitizing pill by a magnifier. Computer technology evaluates the sperm appearance and the way it moves. As long as the computer observes the sperm below the magnifier, it is prepared to create a highly digitized image of each sperm following its speed and path it covers while moving under the magnifier.
The computer technology makes it more convenient for humans to precisely evaluate and monitor the micro size species that are involved in the fertility pattern of male partner. CASA helps in identifying the infertile patient who then needs further testing to determine the causes. You should have this test performed soon when you decide to have a baby.
