Kegg from a Specialist's Perspective

よくある質問

Move beyond "just guessing" in your fertility journey. kegg is a general medical device that measures vaginal changes in about 90 seconds daily, visualizing your body's rhythms as data.
It's a new option that allows you to understand your fertility journey, which previously relied on feelings and intuition, through objective data on "changes in your own body."

Yes, it has been registered in Japan as a general medical device. It is designed for safe daily use.
(Registration number: 13B2X10428006001)

Chosen by those who have even the slightest concern about their current method.
- Those who have just started fertility treatments
- Those who feel limited by basal body temperature and ovulation predictor kits
- Those for whom clinic visits are a burden
- Those who want to thoroughly understand their own bodies

Basal body temperature monitors changes "after" ovulation, while kegg measures the changes in your body leading up to ovulation.

This allows you to grasp trends earlier, a key feature that helps you plan your timing proactively.

This is because it captures the natural changes in your body as data. By measuring the vaginal environment and graphing it on the app, you can use it as "one indicator" to understand your fertile window.
Additionally, the memo function allows you to record test results, supplements taken, menstruation, and whether or not you've had intercourse, enabling you to review the changes in your body and your lifestyle habits all at once.

Demonstrations are also progressing in Japan. Its utility as an indicator for ovulation timing has been examined in fertility treatment settings, including validations at Hamada Hospital in Tokyo and its use in demonstration projects by the Ministry of Economy, Trade and Industry.

By consistently measuring for approximately 90 seconds a day, the device learns your body's rhythm and improves its accuracy.
On average, it is said that your personal trends become visible after 2 to 3 cycles.

It takes just 90 seconds a day. Simply insert the egg-shaped device (approx. 50mm long / 25mm max diameter) into the vagina, take a measurement, remove it, and check the results on the app. The tail part can remain outside, allowing you to measure while doing other things, such as brushing your teeth or blow-drying your hair.

It's okay if it's not perfect. Ideally, it should be around the same time (±2 hours), but even if it's slightly off, data will still accumulate. The key to results is to continue without overexerting yourself.

Do not use during menstruation; resume after menstruation ends. It is designed to be continued without overexertion.

It is designed for safe and comfortable use. Made of soft medical-grade silicone, there is no need to insert it too far. Many users in Japan have reported "less discomfort than expected," and it can be washed and reused, ensuring good hygiene.

No daily charging is required. The app will notify you at the right time, making it easy to continue.

Lady Technology

Lady Technologies is a U.S. femtech company founded with the aim of expanding options for women to better understand their bodies. Kristina Cahojova, CEO and Founder, experienced firsthand the uncertainty and difficulty of continuing fertility treatment, which led her to develop "kegg," a tool that allows women to understand changes in their bodies as data.

In Japan, regulatory compliance was necessary to deliver the product in a way that users could feel safe using. Fermata collaborated with Lady Technologies to register the device as a general medical device and develop a Japanese version of the app, playing a role in making kegg available to Japanese users.
