Computer-aided sperm analysis (CASA) technology shows promise for human clinical semen analysis. Modern platforms offer improved capabilities for assessing functional sperm characteristics, overcoming previous limitations with human samples.

Area of Science:

Reproductive Biology
Andrology
Medical Technology

Background:

Computer-aided sperm analysis (CASA) technology, developed in the late 1980s, excels in analyzing sperm kinematics and semen characteristics in animal species.
Previous CASA applications in human clinical semen analysis faced challenges due to sperm clumping and background debris, hindering accurate digital image analysis.

Purpose of the Study:

To review the enhanced capabilities of modern CASA platforms (Hamilton Thorne CASA-II and Microptic SCA6).
To explore current and future applications of CASA in human semen analysis, focusing on functional sperm characteristics.
To outline validation requirements for CASA as a semi-automated system in clinical laboratories.

Main Methods:

Review of advanced features in two contemporary CASA platforms.
