Good question. Fellow's peer-reviewed, patent-pending Stabilization Technology™ tackles this problem in two ways. First, we keep your sample in optimal condition so that fewer sperm die en route to our lab. Our semen analysis kit includes preservation solution that extends the life of your sample, a gel pack that keeps your sample at the right temperature, and a sensor that monitors the kit's temperature and humidity. The gel pack and temperature sensor are stored securely behind the sample container to ensure they operate as intended. Second, we developed an algorithm that accurately models the rate of sperm degradation over time, allowing us to calculate your sample’s metrics as if it was produced in a clinic. Our process has been peer-reviewed and published in a leading fertility journal (learn more here). Other mail-in semen analyses simply report on the sperm’s quality at the time they receive it—typically 52 hours later—and these results aren’t representative of your actual fertility metrics.
When it comes to your health and fertility results, “close enough” doesn’t cut it. We’ve partnered with top reproductive health doctors to ensure that our test is as robust and accurate as possible.
Unlike our competitors, Fellow is the only mail-in test that operates its own CLIA-certified lab (CLIA Number: 05D2177822). Why does this matter? CLIA (pronounced “KLEE-uh”) stands for Clinical Laboratory Improvement Amendments. Being CLIA-certified means that we are recognized by the federal government for meeting quality regulations for running tests that are used to help doctors and patients make health decisions. Operating our own lab allows us to ensure that every test is done to the highest quality standards ensuring you get the most accurate results possible. Read more about CLIA.
Steps from UCSF, our secure biolab is equipped with cutting-edge technology built exclusively for sperm analysis. In partnership with leading experts and universities, we’re able to pioneer research in male reproductive sciences.
