About Legacy: clinically validated at-home sperm testing & freezing

Legacy (Give Legacy, Inc.) makes sperm simple. We’re a US-based company offering at-home sperm testing and sperm freezing through mail-in kits, so you can check on your fertility or protect it for the future without ever stepping into a clinic.

We offer semen analysis, post-vasectomy testing, sperm DNA fragmentation testing and long-term sperm freezing (cryopreservation).

How it works: Order a kit online. It ships discreetly to your door. Collect your sample at home. On your schedule, in private. Ship it back. Your sample reaches our lab in 21 hours on average, about 30% faster than other mail-in providers. Faster arrival means a healthier sample and more accurate results. Your results arrive within 2 business days in a report reviewed by a physician, with practical tips for improving your sperm health. Legacy is available in all 50 states, starts at $145, and you can pay with your HSA or FSA.

Life doesn’t always go to plan, and your future family shouldn’t depend on timing. We store frozen sperm for up to 25 years. Legacy is the only company that splits your samples across multiple storage sites, so even if something goes wrong at one facility, your future is still safe.

Results you can trust, from home: Our mail-in kit is clinically validated: a 2025 study by our researchers, published in the American Journal of Men’s Health, showed that shipped samples accurately predict the results of a fresh sample. Sperm naturally slow down in transit, so our lab uses a predictive algorithm to adjust for it.We measure semen volume, sperm count, movement (motility) and shape (morphology) with computer-assisted semen analysis (CASA). For a deeper look, our sperm DNA fragmentation test checks the quality of the genetic material inside your sperm. It’s the only validated mail-in DNA fragmentation test in the US.

Every sample goes to our own andrology lab in Hoboken, New Jersey, which is CLIA-certified for high-complexity testing. We’re also approved by New York State for semen analysis and DNA fragmentation testing and licensed as a New York State tissue bank for sperm storage.

We started at Harvard in 2018, went through Y Combinator, and have raised over $50 million from investors including Justin Bieber. Along the way, Y Combinator named us a Top Company, Forbes named us one of America’s Best Startup Employers, the Financial Times ranked us among the fastest-growing companies, and Business Insider picked us as a startup likely to reach unicorn status.
