In the US there are currently 7.7 million women ages 15-44 with fertility issues. Fortunately, women can assess their fertility health by measuring their progesterone levels. However, a product which does so quantitatively and cheaply is inexistent. Our progesterone biosensor will allow women to quantitively read their progesterone levels 4-6 days faster, $70 cheaper, and from the comfort of their homes. This sensor is the first of many we are building with our proprietary platform technology.
