About Legacy
Complete sperm support
Our comprehensive services help your patients test,
improve, and preserve their fertility from home.
improve, and preserve their fertility from home.
Testing from home
Semen analysis
Comprehensive analysis that tests all key metrics of sperm health, giving you the data you need to guide your patients’ treatment.
Advanced semen analysis with DNA fragmentation testing
A measure of sperm’s genetic health that can help shine a light on infertility, miscarriage, or failed IVF cycles.
STI analysis
Tests for 6 sexually transmitted infections from the privacy of home: gonorrhea, chlamydia, hepatitis B, hepatitis C, HIV 1/2, and syphilis.
Fertility improvement
Male Fertility Supplement
Science-backed fertility multivitamin contains 10 active ingredients, including 5 powerful antioxidants, to support your patients’ sperm production.
Virtual fertility consultation
If you’re not able to discuss your patients’ results, we can help. A virtual consultation with a urologist or andrology nurse educates patients on ways to improve and protect sperm health.
Fertility preservation
Male Fertility Supplement
Protect your patients’ ability to have a family if and when they choose.
Cryostorage plans
We offer sperm storage plans from 1 year to 25 years for maximum flexibility and value for your patients.
Our Science
The science of at-home sperm collection
Our kits use an FDA-approved, clinically tested HEPES-based sperm transport media to minimize the decline of sperm quality, plus an insulated kit to regulate sample temperature.
Because the best samples are collected in the comfort of home, mail-in semen analysis is an effective, accessible option for most patients.

Kit validation
Delayed analysis of semen parameters using the Legacy Kit can accurately predict early post-ejaculation values. Reverse prediction models demonstrate high predictive validity, as evidenced by strong correlation and agreement metrics.

Shipment of semen samples using the Legacy Kit has no statistically significant impact on sperm concentration, morphology, or sperm DNA fragmentation as measured by the Halosperm sperm chromatin dispersion test.

What our analysis measures
Semen volume
Sperm concentration
Motility, progressive motility & estimated initial motility
Estimated initial motility refers to the percentage of sperm cells that were likely motile/progressively motile in the patient’s fresh ejaculate. This is based on a model that factors in typical hourly motility decline of samples shipped in the Legacy kit, how long the sample was in transit, and the observed motility of the sample upon arrival to our lab.
Morphology
WHO criteria
DNA fragmentation index
Sperm chromatin dispersion test (Halosperm)
Total motile count
Cryostorage science
All samples are split between multiple cryogenic lab locations for an added layer of security.
CLIA certified

Why at-home sample collection benefits your patients
Our scientific contribution
The science of at-home sperm collection
We conduct original research on sperm health, testing, and preservation — and provide funds to help other researchers make new discoveries.
How it works
01
Order your collection kit online
Produce your sample at home. Use the prepaid label to ship it to our full-service andrology lab.
02
Your sample is analyzed
For pre-vasectomy storage, we’ll do a full semen analysis to ensure your sample is viable for freezing. For post-vasectomy analysis, we measure your sperm concentration (how many sperm) — and we double check.
03
Your sample is frozen
If you’re freezing prior to a vasectomy, your sample will be frozen immediately so you can confidently continue on to your surgery.
04
Get your report
On your digital client dashboard, you’ll see the results of your post-vasectomy analysis, or, if applicable, the details of your storage plan.
05
Using your sperm in the future
You can use frozen sperm for IUI or IVF without a vasectomy reversal or testicular sperm extraction. You can keep your samples in storage for as long as you need without affecting their health or viability.
Get Your Patients Started
Legacy + your practice
Accessible at-home testing and freezing options increase patient compliance — and get you the information you need to make decisions around treatment plans and sperm banking.
