Legacy’s platform treats sperm health as an ongoing health metric

Legacy, the leading digital male fertility clinic, just dropped Sperm Insights — a platform that translates clinical semen analysis data into a personalized, trackable view of reproductive health over time. Developed with CMO Dr. Scott Lundy, it’s built on what Legacy says is the largest sperm dataset held by any clinic or laboratory in the US.

What it does

The core feature is a proprietary Sperm Score: a single metric that summarizes overall sperm health, benchmarks it against age-matched Legacy clients, and tracks changes over time. Beyond the score, Sperm Insights surfaces emerging connections between sperm health markers and broader wellness and longevity indicators — framing male fertility as part of overall health, not a siloed reproductive concern.

The bigger shift

WHOOP, Oura, and Function Health have spent the last several years building the infrastructure for proactive, data-driven health monitoring, and male fertility has sat completely outside that conversation the entire time. It’s been treated as something to address when conception becomes difficult, not as an ongoing signal worth paying attention to. As Legacy CEO Khaled Kteily put it: “Finally, men have a solution to help them understand their bodies, their health, and their fertility.”

Sperm Insights is the attempt to fix that, positioning sperm health alongside VO2 max, HRV, and blood biomarkers as a metric worth tracking before there’s ever a problem.
