Science behind kegg

kegg™ uses advanced sensing technology called impedance spectroscopy for vaginal mucus measurement, which in simple words means streaming small pulses throughout the vaginal environment. Based on their responses, kegg knows how the fluid-structure changes. By sensing the changes of your vaginal fluids with impedance spectroscopy, kegg™ can determine when fertile cervical fluid is present. This process takes about two minutes and your data syncs to your phone in seconds.
