HOW IT WORKS

PVSA is a post-vasectomy semen analysis test kit that allows patients to collect a specimen at home and mail it for laboratory analysis.

Step 1

Collect a semen specimen at home
Privacy, comfort, and convenience with the reliability of a clinical lab.

Step 2

Deposit into collection bottle
PVSA uses a patented fixative that preserves the semen specimen for analysis.

Step 3

Drop specimen box in any US mailbox
Our fixative eliminates the time sensitivity in testing, and can be sent via regular mail.

Step 4

Analysis performed on arrival
The vasectomy results are immediately reported after our analysis is complete.

(1) PVSA is the original home collection kit for post-vasectomy testing by a federal and state licensed clinical lab.
(2) Cost quotes obtained from websites.
(3) Several methods are used to determine the number of sperm per milliliter of semen specimen; the numbers listed are the lowest concentration of sperm detectable by the test; PVSA is one to two orders of magnitude more sensitive than all the other methods.

Semen Analysis Sensitivity

“Sensitivity” means the lowest sperm count a semen analysis test can detect.

PVSA provides physicians and patients with the most reliable analysis of post-vasectomy status.

The Standard Threshold

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.

The PVSA Threshold

With a threshold of 3,300/mL, PVSA detects sperm at much lower levels that standard tests would miss.

Patented Fixative

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.
