Why Legacy?
Legacy was founded at Harvard University by healthcare and fertility experts, and our scientific and medical board is made up of the world’s leading fertility specialists. You can expect a level of rigor and quality that you won’t find anywhere else.
Clinic-grade semen analysis
Many at-home sperm testing options only test sperm count. Legacy’s at-home analysis tests all five key fertility factors: semen volume, sperm count, concentration, motility, and morphology. The results of your Legacy analysis will be as accurate and in-depth as a fertility clinic’s report.
A detailed picture of your fertility
Our lifestyle assessment looks at nearly a hundred factors that may impact sperm health. Our algorithm incorporates your responses, your semen analysis results, and a specialist’s inspection to give you a comprehensive understanding of your fertility.

FDA & CLIA certified laboratories
We hold our partner labs to the highest standards. All Legacy analyses are performed at facilities certified by the FDA and the CDC to adhere to all standards put forth in the Clinical Laboratory Improvements Amendment (CLIA).
Designed for mail-in safety & convenience
Our kits includes a sperm transport liquid that’s clinically proven to protect and extend the life of sperm to allow for overnight shipping, without affecting the health of sperm. Additionally, our kits are insulated and extensively tested to ensure samples.
Scientific standards for semen analysis
We compare your results against the World Health Organization laboratory manual for the examination and processing of human semen: 5th Edition’s evidence-based reference ranges for sperm count, sperm concentration, sperm motility (movement), and semen volume. We also analyze sperm morphology (shape) using Krüger’s strict criteria, an industry-standard methodology.
And you won’t just get the basic numbers. We’ll provide you with in-depth details about your sperm motility and morphology, which can help you and your doctor make decisions about potential next steps in your fertility care.
