About FlowLabs

FlowLabs is a specialized male fertility lab founded by leading physicians and researchers in male reproductive health. We offer accurate, comprehensive fertility testing and help patients and clinicians move forward with greater clarity and confidence.

With locations across Ontario and a mail-in semen analysis kit available across Canada, our goal is to make specialized male fertility testing more accessible, timely, and proactive. We’re here to help clinicians get the best possible information so they can make the best possible decisions for their patients.
