Abstract: The present invention relates to a server for automatically diagnosing male infertility, and to a method for diagnosing male infertility by using the same and, more particularly, to a server that can diagnose male infertility through analysis of sperm motility trajectories and to a method for diagnosing male infertility by using the same. The present invention automates infertility diagnosis through analysis of sperm motility trajectories by using an artificial intelligence model, and can consistently diagnose even male infertility that cannot be diagnosed using existing male infertility analysis methods that inevitably reflect subjective standards. In addition, the present invention can provide automated analysis, and thus shows a significant improvement in analysis time and cost, and can be widely used in the male infertility diagnosis industry.
