• Opionato Mission

    Democratize fertility information and empower women, men, and couples everywhere to understand and act upon their fertility in order to have a child when it's desired and deserved.


    Our aim is to eliminate infertility and the need for expensive and invasive fertility medical interventions.


    We believe that knowledge is power. Understanding your fertility as early on as possible - by obtaining the right information and the right advice at the right time - allows you to act early on. This not only enhances your pregnancy chance now and later but also makes your path to pregnancy smoother, shorter, and less expensive.
