Scientific research investigating the changes in cervical mucus throughout the menstrual cycle dates back to 1946. It is now established that changes in cervical mucus are strongly associated with ovulation and fertility.

Our team of scientists, engineers, and physicians spent years on research and development to apply existing technology to monitor this key fertility sign by measuring shifts in specific properties of cervical mucus that drive fertility status. By measuring these shifts in the cervical mucus, kegg can measure the beginning and the end of your fertile window.

Cervical mucus plays a critical role in conception. It’s a fluid produced by the cervix that nourishes sperm and facilitates sperm penetration and transport for fertilization. 

Cervical mucus is largely composed of mucins (sticky proteins that thicken the fluid) and a water solution which contains mixtures of trace metals, lipids, proteins, enzyme inhibitors, fatty acids, prostaglandin, and antibodies. Prior to and during ovulation, dramatic rises in estrogen, FSH, and LH occur that are associated with dynamic shifts in relative concentrations of the mucus components.

This in turn makes cervical mucus more slippery, wet, and have optimal fertile properties for sperm maintenance and transport to support conception. Without fertile cervical fluid, the fertile window would be limited to just 24 hours. kegg tracks the fertile window at the source: cervical fluid. Using high-sensitivity impedance technology, kegg detects this key fertility sign throughout your cycle in just minutes per day.

Impedance technology, used in a spectrum of clinical applications, is a methodology for determining the amount of resistance to alternating current flow. The amount of resistance is detected by sending small electrical signals through the medium. The changes in the cervical mucus (e.g. water content or electrolyte make up) can alter the flow of electrons allowing us to measure changes in cervical mucus.

Women typically have the most fertile cervical fluid 2–3 days before ovulation. Intercourse on these days tend to offer the best chances for conception. kegg uses impedance to detect these subtle changes in your cervical mucus to predict when the fluid is potentially optimal for conception during your ovulation window.

The term “fertility awareness-based methods” (FABM) refers to different methods of identifying the fertile period during the female cycle.

As women can only get pregnant from intercourse that happens during the fertile window, it’s important to track different fertility signs so you can feel most confident in carefully timing intercourse.

The basis of FABMs relies on a woman’s understanding and recognition of her fertility. There are many methods available to track fertility like the Sympto-Thermal Method, Creighton Method, and more. kegg can complement FABMs or act as a stand-alone reliable fertility tracker to help users detect their fertile window and possible ovulation.
