Legacy, the digital male fertility clinic, has launched Sperm Insights – a product that transforms clinical semen analysis data into a personalized, longitudinal view of reproductive and overall health. The platform is built on what Legacy says is the largest sperm dataset of any clinic or laboratory in the U.S.
The core feature is a proprietary Sperm Score that summarizes overall sperm health into a single metric, alongside age-based benchmarking against other Legacy clients, longitudinal tracking to monitor changes over time, and emerging insights on potential relationships between sperm health and broader wellness and longevity markers.
“Patients often struggle to interpret complex semen analysis results and describe the implications of their testing on their fertility,” said Legacy CMO Dr. Scott Lundy. “This platform provides real-world context grounded in scientific literature and will help individuals understand what their results mean, how they compare to peers, and most importantly, what actions they can take to improve their reproductive and overall health.”
Legacy is explicitly positioning Sperm Insights alongside consumer health platforms like Function Health, WHOOP, and Oura – all of which have introduced single-score health metrics. “Male fertility has been left out of this movement entirely,” said founder and CEO Khaled Kteily. “Finally, men have a solution to help them understand their bodies, their health, and their fertility, made possible by one of the largest male fertility data sets in the world.”
Sperm Insights is available to all Legacy clients and reflects a broader shift in the fertility space toward treating male reproductive health as a proactive, data-driven practice rather than something addressed only when couples struggle to conceive.
