Presentations from the 2025 ASRM Annual Meeting
The presentations demonstrated how the quantification of phosphatidylserine positive (PS+) live sperm, when combined with a traditional semen analysis, provides a more accurate indication of male fertility. Research shows that the PS Score offers stronger stability and predictive value than conventional semen analysis metrics, making it a powerful tool for identifying fertility potential and uncovering issues that standard testing may miss.
