Computer-assisted sperm analysis pdf

  • How does computer assisted sperm analysis work?

    This is sometimes referred to as CASA or computer assisted semen analysis.
    The semen specimen is placed on the stage of the microscope.
    This microscope has a high resolution video camera attached.
    The video camera feeds data into the computer where it undergoes analysis by software..

  • What is Casa method?

    Computer-Assisted Semen Analysis (CASA) enables reliable analysis of semen images, and is designed to process large number of images with high consistency, accuracy, and repeatability..

  • What is Casa method?

    Computer-Assisted Semen Analysis (CASA) enables reliable analysis of semen images, and is designed to process large number of images with high consistency, accuracy, and repeatability.Oct 7, 2022.

Semen samples from 77 men were used to estimate the accuracy and precision of measurements of sperm density, percent motility, and motion characteristics 

Can computer-aided sperm analysis be used in a laboratory?

For sperm analysis, important inter-laboratory variations have been observed in manual analyses.
In this study, a computer-aided sperm analysis (CASA) system was assessed versus manual technique, and specific software modifications were operated to fit the David's classification already used in the laboratory.

How do CASA systems evaluate sperm morphology?

Most CASA systems can evaluate intactness of the plasma membrane of each sperm in a wet preparation, after exposing sperm to fluorochromes.
Using dry preparations of stained sperm, CASA systems can evaluate morphology of the sperm head, acrosomal status, and bending or coiling of the middle piece or tail.

What is computer-assisted sperm analysis (CASA)?

Computer-assisted sperm analysis (CASA) systems have evolved over approximately 40 years, through advances in devices to capture the image from a microscope, huge increases in computational power concurrent with amazing reduction in size of computers, new computer languages, and updated/expanded software algorithms.
