You're in good hands.

Fellow is committed to advancing male reproductive health.

Fellow is more than a partner for clinical semen analysis. We're also at the forefront of large-scale research into best practices and factors impacting male reproductive health.

Compliance and Patient Experience

Contact Fellow for more information

Patients want to test from home.

Scheduling semen analysis at a lab can be awkward and inconvenient, and delay fertility consultations. Our mail-in process streamlines the process and provides an elevated experience for patients.

Fertility specialists need sperm metrics prior to consultation

Easy mail-in testing helps ensure male partners are assessed up front so that both partners can be evaluated in parallel and a path to treatment can be discussed.

Better patient experience. 
Better compliance.

90% of fertility patients complete Fellow semen analysis within two months. 93% of Fellow users rate us an 8 out of 10 or above.
