Kegg Tech Review

Tracking your fertile window each month is an essential component of the conception process, however, many women struggle with pinpointing ovulation or miss their fertile window completely due to having a shorter or longer menstrual cycle than what’s considered to be the standard used by most fertility trackers. Thankfully, there’s now a device available that discovers each woman’s unique fertile window through monitoring changes in electrolytes within cervical fluid.

Kegg Tech has created a 2-in-1 fertility tracker and kegel ball that not only helps women pinpoint their most fertile days but also allows them to complete kegel exercises prior to taking daily readings to support fluid production and strengthen their pelvic floor. Here, I’ll explain how Kegg works and provide you with a review of my experience using this device.

TL;DR: What Is Kegg Tech?

  • Kegg Tech is a femtech company that has created a 2-in-1 fertility tracker and kegel ball
  • This device pairs with an app that allows women to track their fertile days and complete optional kegel exercises
  • Kegg’s daily readings and associated chart are based on fluctuating electrolyte levels found in cervical mucus
  • Women only need to insert Kegg for 2 minutes a day unlike other devices which are oftentimes worn overnight
  • Kegg can detect a woman’s fertile window and ovulation for up to 7 days

What Is Kegg Tech?

Kristina Cahojova, Founder & CEO of Kegg Tech, created Kegg to help women observe their vaginal fluids to better understand their reproductive health and unique menstrual cycles. It’s estimated that ay least 87% of women do not have an “average” menstrual cycle length of 28 days and that many women ovulate before or after Day 14 of their cycle.

When asked about her personal experiences that led to the creation of Kegg, Kristina Cahojova responded,


“I have always struggled with tracking my fertility; my cycles are irregular due to stress and traveling, so the ovulation tests and temperature methods provide limited information about my ovulation and none about my fertile window. Later, when I refused to “fix my cycles” with hormonal birth control, I was told by a fertility specialist to track my vaginal fluids. I was shocked that there is no technology to help me with that. So, I completed my training in the Creighton Model and the Sympto-Thermal Method of fertility awareness. These fertility tracking methods rely on the user’s ability to observe vaginal fluids to understand my reproductive health. Naturally, it left me stressed and anxious as these methods aren’t easy to learn.”


Countless women have tried and failed in respect to their attempts to conceive with the use of BBT and OPKs, and as a result, many of them have turned to the use of cervical mucus tracking to gain further insights and real-time data to improve their chances of becoming pregnant. In fact, women can detect their fertile window and ovulation up to 7 days by monitoring their cervical fluid, whereas OPKs and BBT methods detect ovulation after it’s occurred.

How Does Kegg Fertility Work?

Kegg Tech 2-In-1 Fertility Tracker Review

Kegg Tech is worn each day within the same 2 hour time frame for 2 minutes to record changes in cervical fluid electrolytes. Women will need to pair their Kegg Tech with their mobile app to start the readings, insert the Kegg Tech for 2 minutes, then remove it and review their daily readings.

Kegg relies on impedance technology which has been proven successful at detecting ovulation for decades in animal studies. Basically, Kegg uses very low-level electrical pulses to evaluate how your cervical fluid affects those pulses and then translates those findings into your chart’s peaks and valleys.

What Does Kegg Measure?

Kegg Tech measures changes in electrolytes within cervical mucus throughout a woman’s menstrual cycle based on the presence of estrogen or progesterone. Prior to ovulation, your Kegg values should descend and lead to a valley which indicates that you’re entering your fertile window. Following ovulation, there should be a peak that eventually levels out after a few days.

However, it’s a bit unclear as to which specific electrolytes influence these readings the most. I had read through some older studies related to electrolyte concentrations in women throughout their menstrual cycles and noticed that many of them had mixed results, although one study showed that 5 out of 6 women whose menstrual cycles and cervical fluid were monitored experience peak levels of sodium on the day of ovulation, whereas other electrolytes did not display similar associations.

The study found that “the mean Na concentrations for all individual cycles varied only within the narrow limits of 72-95 JLM Na/gm. of mucus. The maximum levels of Na in the fresh mucus (107-196 JLM/gm.) occurred on the day of ovulation and were usually preceded by a surge from a relatively low value 1 or 2 days prior to ovulation” and “The peak concentrations of sodium in the dry mucus residue of all the women occurred at the time of ovulation .

This event was preceded by a remarkable surge in the concentration of Na from the relatively low level observed 1 or 2 days prior to ovulation and was followed by an equally remarkable drop in concentration 1 day after ovulation. The considerable increase in the concentration of Na, followed by a large decrease a day after ovulation, clearly differentiated the time of ovulation from other periods in the cycle.”


It was also found that 3 of the 6 women had their lowest concentrations of potassium on the day of ovulation and that “changes in the concentration of calcium were very abrupt at the time of ovulation.”

I was intrigued by the study and wanted to confirm whether or not this was the primary factor that influenced Kegg’s readings, so I asked Kegg the following question,


“Is the spike that occurs near ovulation associated with a peak concentration of sodium? And is the chart’s dip then spike associated with the presence of potassium, calcium, magnesium, zinc, iron, or copper?”


The UX/Product Manager provided me with the following answer,


“The major ions at play are Na+ (sodium), K+ (potassium), Cl~ (chloride), and Ca2+ (calcium) The literature implies that potassium, calcium, and chloride are the controllers but the amount of water is maximized near and during the time of ovulation. Water content impacts the impedance reading so we can’t say it’s specific electrolytes but rather the electrolyte concentration.

The research is limited on the concentration of specific ions within the fertility cycle. We hope to gain greater understanding, and hope that current and future research can offer deeper insights into this subject and look forward to its potential impact on women’s health.”


Thus, the general electrolyte concentration is what’s tracked by Kegg, but I will update this review in the future as more research is available to answer this question and will inquire more about the graph’s exact parameters so that women, including myself, can have a better understanding of the graph and what it represents in further detail.

However, in the meantime, here’s what we currently know about the general changes that take place each month in a woman’s cervical mucus:

Kegg Review – My Experience Using The 2-In-1 Fertility Tracker And Kegel Ball

Best Body for Baby - Part 3

I got to try out Kegg’s 2-in-1 fertility tracker and kegel exerciser to help me track my fertile window. Here’s a closer look at my experience using this device.

What’s Inside The Kegg Tech Box?

  • complete charging set
  • user manual

How I Used Kegg For Fertility Readings

Prior to using my Kegg, I first had to register it online via its mobile app using the supplied barcode within the kit. Following set up, I was then able to pair my Kegg with my mobile app via BlueTooth to start my daily readings.

This is the message you’ll receive when you first open the app and select to use your Kegg for daily readings. You’ll need to turn on Kegg by holding down the center button and then wait for it to vibrate once and turn green.

You’ll then be asked to choose whether you want to take your daily fertility reading on its own or complete kegel exercises along with your daily fertility readings. The kegel exercises are helpful to do prior in order to generate more cervical mucus and only take an additional 3 minutes to do.

If you choose to only complete your daily readings, you’ll be prompted to insert your Kegg and wait for it to vibrate once. After a single vibration has occurred, you’ll need to wait around 2 minutes for the test to complete. You’ll be notified that the test is done once you feel a set of 2 vibrations.

What My Kegg Tech Fertility Readings Looked Like

After you’ve completed your daily readings, your chart will then be updated to reflect your fertility status and you’ll be able to view your chart’s patterns. Here’s an example of what your Kegg chart should look like throughout one cycle compared to a chart that depicts the probability of pregnancy from intercourse on days relative to ovulation below it (you’ll notice it’s an inverse relationship):

In comparison, here’s what my readings looked like for the second month I used Kegg (you’ll notice that I did not use Kegg every day, however, I figured out my fertile window after the first month of use and used Kegg in combination with my Ovia fertility tracker to pinpoint my fertile window and ovulation for the following month as pictured below):

As seen above, I was able to get my fertility tracker to match up with Kegg after only using it for 2 months and Kegg actually pinpointed my ovulation on the 18th as shown by the peak that took place. Not only did I figure out my fertile window but I also timed intercourse perfectly for my desired result. 😉

Something I want to point out about my individual menstrual cycle which isn’t clear from the above images is that I actually ovulated on Day 25 of my cycle, whereas in the past I had mistakenly thought that I ovulated on Day 21. Kegg was the only device and method of fertility that worked for me and there’s a huge chance that I would still be trying to conceive for several more months if I had not used it.

How I Used Kegg Tech For Kegel Exercises

If you decide to use Kegg for kegel exercises, you can expect to follow these same instructions:

Following each round of squeezing, you’ll be provided between 5-10 seconds of rest. The exercises are very easy to complete and help prep your body to provide better samples for the readings.

What I Loved About Kegg Tech

I was so relieved that I only had to insert the device for 2 minutes each day! Many other fertility trackers are designed to be worn throughout the night and I’m not a fan of this as this can be quite uncomfortable and also lead to irritation.

I also appreciated that Kegg sent daily reminders for tracking and was the most reliable tracker I’ve used thus far.

What I Wish Kegg Tech Did Differently

There are only two things that I wish that Kegg did differently. First, I wish that Kegg offered additional and longer pelvic floor exercises. While its current exercises do work, I feel that many women would benefit from other variations and time durations

Additionally, I wish that Kegg Tech would provide more information on the parameters used on its chart and that there was a deeper explanation available for the changes that take place.

Take-Home Message

I was thrilled to try out Kegg Tech’s 2-in-1 fertility tracker and kegel exerciser! It was incredibly helpful to have a cervical mucus tracker that confirmed whether or not my period tracker was somewhat accurate in my fertility readings. It actually helped me to determine that my tracker was off by 4-5 days for ovulation and I was able to successfully time intercourse during the 2nd month of trying to conceive using Kegg.

Without Kegg Tech there’s a good chance that I would have timed intercourse incorrectly and that it would have taken longer to conceive. If you’re like me and your day of ovulation happens to be around day 25, NOT day 14, then Kegg is an invaluable asset to your fertility journey.
