Why Choose MFL

How can we help you?  Client service is our #1 priority.  To meet this goal, we offer:

    Professional service dedicated to male fertility testing.  This is all we do. 
We are the sperm experts.

    A staff who understand your concerns, and are the most highly trained Clinical Laboratory Andrologists in the region.

    Individualized, state-of-the-art procedures for sperm freezing and sperm recovery. We don’t do high-production sperm processing like a sperm bank. Not everyone is the same, so we tailor our procedures to achieve the best outcome for you. Patient-centered care is not always the easiest or least expensive, just the best.

    The most advanced testing, at reasonable prices. Tests you won’t find elsewhere, such as computerized sperm analysis, Comet assay for sperm DNA fragmentation, hyperactivation, acrosome reaction and other sperm function tests, electron microscopy, reactive oxygen species and more.  

    Tests and procedures are backed up by published studies, so you’re getting validated, meaningful results.

    We’re part of the UW Medicine team; bringing basic research to the clinical lab and great clinical care to you.
