About Us

The Mission

Underdog Fertility was founded by two fathers and a mother who care deeply about helping others start a family.  

We're on a mission to provide practical tools grounded in science to improve men's reproductive health. From research, we believe that optimal sperm quality is essential when planning your new or growing family. 

We've leveraged our engineering and design backgrounds to develop The Underdog in consultation with a network of doctors and urologists to ensure our solution is safe and optimal.

We were lucky to be able to have kids. We want to help other couples get there too. 

It's the most important journey of our lives. Let's get started.
