Global fertility has been declining at a fast pace. From 1990 to 2019, the fertility rate fell from 3.2 to 2.5 live births per woman. We are talking to Pascal Koenig, co-founder and board member of Ava about tackling infertility with science. Ava is clinically proven to identify both the opening and closing of the fertile window, letting you know your five best days to try for a baby. In a world where fertility is falling due to lower childhood mortality rates, access to birth control, and focus on career development for women and men, one in seven couples may have difficulties conceiving. With medical treatments being considerably expensive, Swiss startup Ava has created a wearable to identify a woman’s fertile window based on 3 million biomarkers.
