The researchers, led by experts in the field of animal reproduction, compared the performance of the Ongo Semen Analyzer to the traditional laboratory-based CASA method, SpermVision. By analyzing semen samples from 10 stallions at different concentrations, they were able to assess the accuracy and reliability of the Ongo Semen Analyzer in measuring total and progressive motility.

One of the most significant findings of the study was the strong correlation between the motility data obtained from the Ongo Semen Analyzer and the CASA system, particularly at the recommended concentration for equine artificial insemination (50 × 10^6 sperm/ml). This correlation suggests that the Ongo Semen Analyzer can be used interchangeably with CASA, providing veterinarians and breeders with a reliable and portable alternative for semen analysis.

The study also highlighted the influence of final sperm concentration on the total motility as analyzed by the Ongo Semen Analyzer. While higher motility was observed at 100 × 10^6 sperm/ml compared to 25 × 10^6 sperm/ml, this variability did not significantly affect the total motility when assessed by SpermVision. This finding underscores the importance of using the recommended semen concentration for accurate results when using the Ongo Semen Analyzer .

Another crucial aspect of the study was the assessment of theOngo Semen Analyzer's precision and repeatability. The low intra-assay variation demonstrated the device's ability to provide consistent and reliable measurements, which is essential for making informed breeding decisions in a clinical setting.

The portability and practicality of the Ongo Semen Analyzer make it an attractive option for professionals in the field of animal reproduction. By eliminating the need to transport samples to a laboratory for analysis, the device saves time and reduces the risk of sample degradation, ultimately leading to more efficient and effective breeding programs.

In conclusion, the scientific study published in Reproduction in Domestic Animals provides strong evidence supporting the use of the Ongo Semen Analyzer for semen analysis. The validation of this portable CASA device by researchers from Vetmeduni Vienna is a significant step forward in the field of animal reproduction, offering veterinarians, breeders, and semen collection centers a reliable and practical tool for optimizing their breeding programs. As mobile CASA technology continues to advance, it is likely that more professionals will adopt these portable systems, leading to improved success rates in animal reproduction.
