Clinically validated¹ analysis powered by Fellow's innovative mail-in kit.
Our process is peer-reviewed to provide clinically valid results for samples produced up to 52 hours before they reach our lab.¹ Our proprietary algorithm accounts for sperm's natural rate of degradation over time, allowing us to calculate a sample's metrics just as accurately as if it had been produced and analyzed within 1 hour of ejaculation.
Clinically validated accuracy
Fellow's validation study, published in the peer-reviewed journal Fertility and Sterility, demonstrated the accuracy of the Fellow test. Our mail-in semen analysis testing system has a strong degree of correlation between 1-hour and delayed SA testing. This test may be used in clinical practice to evaluate semen quality for fertility evaluations.

Independently reviewed
An independent review of our validation study noted the benefits of Fellow 's accurate mail-in test:
"The ability to perform at-home semen analyses testing has numerous clinical and patient implications, including reducing patient anxiety, improving convenience, and potentially the ability to see higher levels of patient compliance."
—Thomas A. Masterson, M.D. & Premal Patel, M.D.
Clinical implications of home-based sperm testing
The ability to perform at-home semen analysis testing has numerous clinical and patient implications, including reducing patient anxiety, improving convenience, and potentially the ability to see higher levels of patient compliance (3).
Further, another clinically important implication of at-home testing is the potential for better standardization of results. Routine semen analysis is fraught with interobserver variability. As such, a centralized location for evaluation can minimize interobserver variability and, thus, improve the diagnostic utility of the test results
Our Vision
We see a routine test as a potential
canary in a coal mine
With patient consent, each test contributes to a biobank of semen samples that can be used to yield breakthroughs across medical disciplines. In partnership with leading experts and universities, we pioneer research in male reproductive sciences. Read our abstracts and articles here.
