kegg records the changes and trends in vaginal environment and cervical fluids to determine the fertile window. Common electrolyte level trends occur throughout the fertility cycle. As egg follicles mature within a woman’s ovaries, the chemical composition of the cervical mucus changes. This is what kegg records. As estrogen increases the cervical mucus becomes more welcoming and nourishing to sperm, allowing sperm to survive on their journey to the egg.
kegg creates personalized fertility predictions based upon the user’s readings and past cycle data. With each completed cycle, kegg’s fertility predictions become more and more personalized.
