Cover Story: The analysis of semen quality is critical in reproductive biology. Although most laboratories use commercial and private computer-assisted sperm analysis systems, in recent years, certain free and open-source software (OSS) alternatives have emerged. OSS can reduce the costs that research groups have to face and may offer important solutions for challenging research endeavors. Due to the open philosophy of OSS, new tools for assessing different parameters related to sperm functionality can be incorporated. In this work, we present an extension of the OpenCASA software, previously developed OSS for sperm quality analysis. In addition to the motility, chemotaxis, viability, and morphometry analysis, the extension will allow researchers to carry out three new analysis: chemotaxis accumulation, plasma, and acrosome membrane integrity and sperm concentration evaluation.
