Far and Away the Most Sensitive Test
3,000 sperm / mL
PVSA mail-in kits began development over 30 years ago to collect semen samples for NIH funded research.
Over the decades, the kit has been perfected and the laboratory process refined. It is now, by far, the most sensitive test for sperm available.
PVSA uses a patented fixative that stabilizes sperm in transit and introduces a predictable dilution factor for a far more sensitive test in the lab.
A standard test with a threshold of 100,000/mL will only show ‘sperm detected’ if there are more than 100,000 sperm/mL. Below that, it reports ‘none detected’ — even if sperm are present. PVSA detects down to 3,300 sperm / mL.
Transparent Pricing
PVSA Kits are $50 each ($90 for two kits), and it’s the same price for everyone (doctors, patients, and clinics). Our mission is to expand affordable access to highly sensitive, CLIA-certified semen testing to improve outcomes and compliance in men’s reproductive care. Learn more about our IMPACT.

Post-Vasectomy Testing and Vasectomy Monitoring
Vasectomy Status Checkups
Vasectomies can occasionally fail years after the procedure.
In rare (roughly 1%) of cases, the vas deferens spontaneously reconnects — a process called recanalization. Periodic PVSA tests can monitor the status of a vasectomy.
