Kegg Fertility gives you a way to track your cycle by focusing on your body's natural signals, specifically cervical mucus. Unlike other methods that rely on hormone test strips or temperature tracking, Kegg claims to take just a few minutes a day and connects to an app that helps you understand your fertility status in real-time.
In this review, you'll learn how Kegg works, what it does well, and where it might fall short. You'll get a clear overview of its main features, how it fits into different types of cycles, including irregular ones, and what to consider before using it. This will help you decide if it suits your needs and fertility goals.
Kegg Fertility may help you track your fertility by monitoring your cervical mucus, one of your body's natural fertility indicators. The device is small and intended for daily use, usually taking just a couple of minutes each day.
As per the official website, Kegg Fertility connects to a smartphone app that provides you with personalized insights into your fertility window based on the data it collects.
The makers of Kegg claim that this method can help you identify your most fertile days and also help you learn about your irregular cycles or hormonal imbalances, where fertility signals can be harder to interpret.
Kegg is FDA-registered as a medical device, which supports its credibility. However, the claims about its accuracy and effectiveness come from the company's research and user experiences, so results may vary.
The makers state that Kegg can help increase your conception chances by helping you identify your optimal days to try for pregnancy, especially if you face challenges like irregular cycles.
As per the official website, Kegg Fertility works by measuring the electrical impedance (or conductivity) of your cervical mucus. During your fertile window, cervical mucus becomes clear, stretchy, and alkaline. This creates a suitable environment for sperm to survive for up to five days, travel through the reproductive tract, and reach the egg. Outside of this fertile period, the mucus thickens and becomes more opaque and acidic, potentially protecting against harmful bacteria and reducing sperm survival.
As per the usage procedure, the maker highlights that you insert Kegg vaginally at a time that suits your routine, and within less than two minutes, it analyzes your cervical mucus.
The Kegg Fertility device sends a low electrical current through the mucus and measures the resistance, or impedance, to this current. Since the ionic content and hydration of cervical mucus fluctuate during your cycle, these changes directly affect its electrical impedance, allowing Kegg to assess your fertility status.
This impedance data is then wirelessly transmitted to the Kegg smartphone app, where it's processed and interpreted. The app generates personalized fertility and cervical mucus scores, reflecting your current fertility status and helping you identify your fertile window.
Kegg detects cervical mucus changes that happen before hormonal or temperature shifts, offering potentially earlier and more accurate identification of your most fertile days.
Research published in journals like Fertility and Sterility and Contraception and Reproductive Medicine shows that electrical impedance measurements strongly correlate with ovulation confirmed by ultrasound and hormone levels. These studies also highlight that Kegg's method provides significantly higher sensitivity and specificity in predicting fertile days compared to basal body temperature tracking.
According to the makers, Kegg also includes an optional guided Kegel exercise feature available in the app. This routine helps you strengthen your pelvic floor muscles, which can decrease injury risk and promote faster healing after childbirth, complementing your fertility journey.
The Kegg fertility tracker is a medical-grade device designed to help you pinpoint your fertile window by analyzing changes in your cervical mucus. When you first receive your Kegg, you'll find the device itself, along with a charging cradle, cable, and wall adapter. The makers suggest beginning by charging the device and then placing the head of Kegg into the cradle and plugging it into a power source. A pulsing yellow or orange light means it's charging, and a steady green light shows that it has a full charge. Next, download the Kegg app from your phone's app store, available on both iOS and Android and create an account. Register your Kegg device by scanning the QR code or entering the serial number.
As per the makers, for everyday use, take your Kegg reading once daily, ideally at the same time each day within a consistent two-hour window, but avoid taking readings during menstruation. Find a comfortable position, whether standing, lying down, or sitting, and try to maintain the same position for each reading to ensure consistency. When the app prompts you, press the side button on the device to power it on, and it will vibrate once and flash green when ready.
Then, open the app, tap the plus sign on the home screen, and select your routine, either with or without the optional Kegel exercises. Insert the ball-shaped end of Kegg fully into your vagina, leaving the tail outside and facing forward. Avoid using lubricants, although rinsing the device with warm water before insertion can make it easier to use. Once inserted, stay still for about two minutes while the device takes a reading. You'll feel one vibration when it starts and two vibrations when it finishes. After the final vibration, remove Kegg as the app instructs and hold it close to your phone to transfer and save the data wirelessly.
After each use, clean the Kegg device with warm water and soap, paying special attention to the metal parts, and avoid scratching the surface. Store the device safely in its case or charging cradle. The app will provide you with personalized Fertility and Cervical Mucus Scores based on your readings, helping you track your most fertile days and ovulation probability.
The makers advise that Kegg should not be used during menstruation, pregnancy, or if you have vaginal pain or infection. If you experience any discomfort, stop using the device and consult your healthcare provider. It's important to understand that Kegg is not a contraceptive and does not guarantee pregnancy.
The best place to purchase Kegg Fertility is directly from the official Kegg website. There, you typically get the lowest price, enjoy free same-day shipping, and benefit from a 12-month pregnancy guarantee. This guarantee includes full refund eligibility if you do not conceive within a year of consistent use, making it a risk-free option for many users.
Kegg can fit seamlessly into your daily routine by requiring just a quick, two-minute intravaginal reading to analyze cervical mucus electrical impedance. Unlike urine-based hormone monitors like Mira and Inito, which need urine samples, dipping test wands or strips, and waiting 20 minutes or more for results, plus recurring purchases of test consumables, Kegg's process is simple, non-messy, and requires no ongoing costs. Similarly, while OvuSense offers a hormone-free approach by tracking core temperature overnight, it requires wearing a sensor all night and syncing data later, which some may find less convenient than Kegg's quick morning routine. This makes Kegg the fastest and least disruptive option for daily fertility tracking.
Kegg measures changes in cervical mucus electrolyte levels in real-time, detecting your fertile window several days before ovulation. This early prediction helps you plan intercourse optimally, unlike basal body temperature (BBT) methods, which only confirm ovulation after it happens. Mira and Inito, on the other hand, use urine hormone analysis, tracking multiple hormones like LH, E3G, PdG, and FSH, to predict ovulation with very high accuracy and are especially helpful for users with irregular cycles or PCOS. OvuSense monitors core body temperature overnight to confirm ovulation retrospectively and offers some predictive trends with continuous use, but it is less immediate than hormone or mucus-based tracking.
Kegg offers hormone-free fertility tracking by analyzing cervical mucus electrically without requiring urine or blood samples. This avoids hormone exposure and invasive sample collection, appealing to those who prefer natural, non-hormonal methods. OvuSense is similar in being hormone-free and non-invasive but requires overnight vaginal wear. In contrast, Mira and Inito rely on daily urine samples for hormone metabolite detection, which some may find inconvenient or intrusive.
The Kegg app translates your daily mucus readings into simple fertility scores, predicts a 5-day fertile window, and charts cycle trends, making data easy to understand and use for planning conception. Mira and Inito provide more detailed hormone-level data and advanced charting features, allowing deeper insight and extensive cycle tracking, which may be preferred by users wanting comprehensive hormone analytics. OvuSense offers basic cycle charts and ovulation confirmation without granular hormone data.
As per its official site, Kegg is a one-time investment device with no need for ongoing purchases of test strips or wands, making it more budget-friendly for long-term use. Mira and Inito require continuous buying of test consumables, which can cost around $90+ per cycle, adding up significantly. OvuSense, like Kegg, is a one-time purchase without consumables, offering a similarly cost-effective approach.
Unique among these options, Kegg doubles as a Kegel exerciser, helping strengthen pelvic floor muscles to support reproductive health and postpartum recovery. Mira, OvuSense, and Inito do not offer pelvic floor exercise features, making Kegg distinctive in combining fertility tracking with pelvic health benefits.
You need to insert Kegg into your vagina every day (except during menstruation) for about two minutes to take a reading. This daily intravaginal use might be uncomfortable or difficult, especially if you have pelvic health issues like vaginismus or endometriosis. Handling and placing the device internally can cause discomfort or anxiety. If you have such conditions, you should check with your healthcare provider before using Kegg.
You have to use Kegg within the same two-hour window each day to maintain accurate fertility tracking. This means taking the reading at roughly the same time every day, which might not fit well if your schedule varies or you travel often. Missing this window can reduce how consistent and reliable your fertility predictions are because cervical mucus changes throughout the day.
Kegg's accuracy is best when you have regular menstrual cycles. If your cycles are irregular due to conditions like PCOS or endometriosis, the readings may be less reliable. The device may produce false positives (marking non-fertile days as fertile) or false negatives (missing actual fertile days). Since Kegg isn't clinically validated for irregular cycles, you might want to consider hormone-based trackers if you need more precise data.
According to the official site, you may return your Kegg device within 30 days of delivery for a full refund only if it is unopened, unused, and still in its original sealed packaging. Because Kegg is an intimate health product, returns are accepted strictly when the device has not been used, and the packaging remains sealed.
Kegg also offers a 12-month pregnancy guarantee. If you use the device as directed for at least 10 consecutive cycles (about one year) and do not conceive, you can request a full refund. To qualify, the makers mention that you use Kegg daily (except during menstruation) within the same 2-hour window each day, be within reproductive age, and have not used hormonal birth control for at least three months prior. You should also not be within six weeks postpartum, not currently breastfeeding (with at least two cycles since weaning), and ovulate regularly.
If your Kegg device is defective due to manufacturing faults within one year of purchase, the makers mention that you can return it for a refund or replacement, even if you have opened the package or used the device.
To initiate a return or refund, you must contact Kegg customer support to get a Return Authorization number and instructions. Shipping costs for returns are typically non-refundable unless the product is defective.
The Kegg Fertility Tracker and the Mira Fertility Tracker are both advanced at-home fertility monitoring tools designed to help users pinpoint their fertile window. However, they differ substantially in technology, methodology, and cost structure. While both share the overarching goal of supporting conception, their core tracking mechanisms and associated costs highlight important distinctions.
The most fundamental difference lies in what each device measures. Mira tracks urinary reproductive hormones, including LH, E3G (a form of estrogen), PdG (a progesterone metabolite), and optionally FSH, to predict and confirm ovulation with lab-grade precision. This hormone-centric approach provides a detailed hormonal profile throughout the cycle.
On the other hand, Kegg evaluates electrolyte changes in cervical mucus, a direct fertility indicator. It uses a vaginal sensor that, in just 2 minutes per day, measures the shifts in cervical fluid composition that occur during the fertile window.
In terms of ease of use, Kegg offers a significantly more streamlined experience. Users simply insert the Kegg sensor for a brief reading, with no mess or additional supplies required. Mira involves a more hands-on process, needing users to collect a urine sample, dip a disposable test wand, insert it into the analyzer, and wait around 21 minutes for hormone results to sync via Bluetooth to the Mira app. This process is more time-consuming and involves more maintenance.
Mira's major advantage, however, is the depth and accuracy of its hormonal insights. It's particularly valuable for people with irregular cycles, PCOS, or those undergoing fertility procedures, who may benefit from quantitative hormone tracking. Mira also allows you to track multiple hormones simultaneously, offering a more nuanced view of ovulation and luteal phase health, information not accessible through cervical mucus alone. Kegg, meanwhile, is better suited for people who trust cervical mucus as a natural indicator and prefer a less invasive, time-saving, and hormone-free tracking method. It also supports users with PCOS or cycles after age 40, as its algorithm adapts to personal trends in cervical fluid over time.
Both Kegg and Mira are FDA-registered medical devices and come with companion apps for personalized fertility insights. While Mira's app emphasizes numeric hormone trends and predictive charts, Kegg's app provides a Fertility Score and Cervical Mucus Score, giving a more intuitive overview. Kegg also offers the bonus of optional guided Kegel exercises, supporting pelvic health.
The Inito Fertility Monitor analyzes your fertility by measuring four key reproductive hormones in your urine such as estrogen (E3G), luteinizing hormone (LH), progesterone metabolite (PdG), and follicle-stimulating hormone (FSH). This comprehensive hormone panel gives you a detailed, clinical insight into your menstrual cycle, allowing you to identify up to 6 fertile days per cycle, accurately predict your fertile window, and confirm ovulation through PdG measurement with clinical-level accuracy.
However, Inito requires you to collect a urine sample daily and dip disposable test strips for about 15 seconds, which a smartphone-connected monitor then scans. The process takes around 10 minutes per test and involves ongoing costs for replacement test strips.
In contrast, Kegg tracks fertility by analyzing your cervical mucus via vaginal data, which is crucial because fertile cervical mucus is essential for sperm survival and successful fertilization. Kegg delivers personalized daily fertility scores in just about 2 minutes per day by inserting a sensor vaginally without needing urine samples or disposable consumables. This makes it a simpler, non-invasive, and more cost-effective option with no monthly or refill fees. It's especially suitable for women with irregular cycles, PCOS, or those trying to conceive after 40. While Kegg does not measure hormone levels directly nor confirm ovulation, it excels at pinpointing the days when your cervical mucus is most fertile, providing actionable daily insights to maximize conception chances.
OvuSense and Kegg differ fundamentally in their technology and measurement methods. OvuSense uses a patented continuous core body temperature (cCBT) sensor worn overnight vaginally, tracking progesterone-driven temperature shifts with 99% accuracy to predict and confirm ovulation in real-time.
In contrast, Kegg analyzes cervical mucus quality, a critical factor for sperm survival, through a quick daily 2-minute vaginal reading that measures mucus hydration and consistency, providing a personalized fertility score.
OvuSense offers detailed all-night temperature curves and cycle pattern flags and is particularly helpful for women with PCOS or irregular cycles, promising conception up to 15 months faster than traditional methods. Kegg emphasizes ease of use with brief daily readings, no overnight wear, and optional guided kegel exercises to support reproductive health.
OvuSense excels by detecting ovulation via temperature despite hormonal imbalances, while Kegg measures mucus directly, reflecting fertility status in real-time. In terms of ease of use, OvuSense requires overnight sensor insertion and morning syncing, whereas Kegg needs only a short daily reading without overnight wear.
OvuSense requires an upfront sensor purchase plus a subscription for full access to app features, and it is HSA/FSA eligible.
In contrast, Kegg offers a one-time purchase with no monthly fees or consumable refills, along with a “Get Pregnant or Money Back” guarantee, making it especially appealing for people who want financial reassurance.

To evaluate Kegg Fertility, we looked closely at verified customer experiences shared on Amazon to understand how the device performs in real-world use. We focused on effectiveness, ease of use, reliability, and customer support, key factors that matter most when you're trying to conceive.
Effectiveness stood out in several reviews, with users reporting successful pregnancies after just one or two cycles of using Kegg. These stories came from people with complex fertility histories, including advanced maternal age and previous failed IVF attempts, suggesting that Kegg could be a reliable tool when it works properly.
Many reviewers highlighted how quick and simple the daily readings are, just two minutes a day, with data synced straight to the app. Users appreciated the personalized tracking and the fact that Kegg is a one-time purchase, making it more cost-effective compared to fertility trackers that require ongoing test strip purchases or subscriptions.
However, while some users had flawless experiences, others ran into technical problems, particularly with the device failing to take readings during crucial fertile windows. A few noted that the device's need for consistent daily timing and a gap after intercourse made it less practical for people with demanding or irregular schedules.
Customer support was another weak point. At least one reviewer described a drawn-out, frustrating process trying to get help for a malfunctioning device, raising concerns about the company's responsiveness and how they handle warranty claims.
Kegg Fertility offers the best value for money at $269. You get a device valued at $299 plus several bonuses, a pregnancy guarantee, cycle chart reviews, lifetime Kegel exercises, and community access worth over $500 combined. With no ongoing fees, it's a strong one-time investment, especially if you're focused on cervical mucus tracking and want added fertility support.
Inito comes next at $99, delivering essential hormone tracking at the lowest upfront cost. It's suitable for iPhone users looking for a budget-friendly entry point. Though you'll need to restock test strips, the base package is generous for the price.
Mira ($259) gives advanced hormone insights with high accuracy but requires ongoing purchases of test wands, which impact long-term value. OvuSense starts cheap at $129 but shifts to a $35/month model, making it the most expensive over time. It's only worth it if you need continuous core temperature tracking for complex fertility issues.
Kegg fertility may help track your fertile window by measuring changes in electrolyte levels in your cervical mucus. It could also support your pelvic health by doubling as a Kegel exercise device. This device might especially help if you have irregular cycles, giving you clearer insights into your most fertile days without the need for hormone testing or expensive monthly supplies.
However, keep in mind that daily intravaginal use is required (except during menstruation), which might cause discomfort or irritation for some, particularly if you have sensitive vaginal tissue, endometriosis, or pelvic pain. The necessity to take readings consistently within the same 2-hour window each day can also be demanding and may not fit easily into your routine.
While Kegg provides valuable information, it's important to understand that cervical mucus changes alone are not the sole indicator of pregnancy or ovulation. Fertility involves multiple complex factors, including hormone levels, uterine health, and overall reproductive function, which Kegg does not measure directly.
However, while cervical mucus can be a fertility sign, relying solely on one indicator can sometimes be misleading, especially if you have underlying hormonal imbalances or reproductive conditions.
It's important to weigh your personal comfort and health factors carefully and consider consulting with your doctor before starting, especially if you have any pelvic or reproductive health concerns.
