Ongo Compact is a portable, computer-assisted semen analyzer that uses the same methodology as a CASA system. It detects sperm using short video sequences to determine concentration and tracks their movement behavior to determine motility. Our device uses state-of-the-art technologies such as lighting, optical imaging, video recording, automatic focusing, microcomputers, and heating, all of which are contained within a small box. While desktop CASA systems offer additional features such as sperm morphology analysis, Ongo Compact is a cost-effective and portable alternative for accurate semen analysis.
