Femtech "Kegg," which measures the fertile window from cervical mucus, begins clinical research with the University of Tokyo

"Kegg" is a device that measures the state of a woman's cervical mucus to identify her fertile window.
As ovulation approaches, the body secretes more cervical mucus to help sperm reach the uterus. This mucus is characterized by its stickiness. Currently, women manually check the stickiness and stretchiness of their cervical mucus to determine their fertile window. "Kegg" automates this process, collecting data with technology.

To ensure that "Kegg," a device inserted into the vagina, can be safely and securely delivered to consumers, it must be approved as a medical device. As a first step towards this, we have initiated a clinical trial in collaboration with Hamada Hospital, with the aim of demonstrating the effectiveness of the data measured by "Kegg." fermata is responsible for device procurement, while Hamada Hospital collects data, and the effectiveness of the data will be studied through continuous use by patients attending Hamada Hospital.

In this clinical trial, we will acquire various data, such as the concordance between the device-measured state and the subject's subjective state, the correlation with bodily conditions like odor and breast tenderness, the agreement rate with ovulation dates predicted from clinical data, and pregnancy probabilities.
