What Is a Fertility Monitor?

Fertility monitors are electronic devices that will help boost your awareness surrounding your fertility throughout your menstrual cycle.

Depending on the type you purchase, they may monitor any changes occurring in the hormone levels in your urine. Some check your basal body temperature, the electrical resistance of vaginal fluids and saliva, or perhaps a combination of everything.

Basically, a fertility monitor will relieve you of some of the guesswork that often comes with trying to conceive. It will detect the clues we would otherwise overlook, or be unaware of, to optimize our chances of getting pregnant.

How Fertility Monitors Work

Most fertility monitors work by tracking two hormones — estrogen levels in the urine and luteinizing hormone (LH).

The latter is a crucial hormone when it comes to fertility — it controls the functions of the ovaries (1). Just before ovulation, the levels of LH increase, stimulating the ovaries to release eggs.

Once your menstrual cycle begins, the fertility monitor will, generally, have you perform a test. Depending on the type, this might include a urine sample, vaginal liquids, saliva, or your temperature. You will usually have to repeat this for 10 to 20 consecutive days, dependent on the type of monitor and length of your cycle.

The monitor should then be able to work out which days are your “peak” days, and when you’re “high” or “low.” There are also other types that will show a red or green light, indicating when intercourse is optimal or not (2).

How Accurate Are Fertility Monitors?

Providing that you use them correctly, most fertility monitors have an average accuracy of 97 percent — some as high as 99 percent (3).

That said, their accuracy depends highly on how you use it — it’s essential to follow the instructions to the letter. Test every day that the monitor asks you to. Additionally, if your monitor requires a urine sample or basal body temperature, do this in the first time you urinate in the morning, and the temperature is taken before getting out of bed.

Besides using the fertility monitor, it’s also essential that you know what’s going on in your body.

What May Affect the Results?

The accuracy of course also depends on any interfering factors. These can include:

  • Existing conditions: Such as polycystic ovarian syndrome (PCOS) or luteinized unruptured follicle syndrome. Both of these conditions may cause a “false” peak or premature peaks.
  • Certain medications: These may include drugs containing hCG, menotropins, or danazol.
  • Current pregnancy or recent pregnancy: This will, for obvious reasons, affect the levels of hormones.

Additionally, if you’re struggling with infertility, your doctor is likely treating you with medicines containing Clomiphene citrate, such as Clomid® (4).

In this case, it’s recommended that you consult your physician about when you can begin to use a fertility monitor. These medicines will impact the results. Therefore, you should generally wait for three days after taking the last dosage.

Different Types of Fertility Monitors

Like many other tools on the market, there are different types of fertility monitors. Some focus on hormones in the urine, vaginal fluids and saliva, basal temperature, or a combination.

Here are two examples:

  • Digital fertility monitors: These are usually the easiest to use — there’s a screen which displays fast and readable results. They’re generally used to track hormones in the urine, or resistance in the vaginal fluids and saliva.
  • Wearable fertility monitors: Wearables are usually those that track your basal body temperature and perhaps heart rate. These generally consist of a small device that you place somewhere on your body, and it syncs with your phone.

The Best Fertility Monitor of 2022

Here are our favorite fertility monitors on the market.

1. Lady-Comp Fertility Monitor

Best Digital Fertility Monitor

For our choice of the best digital fertility monitor, we selected the Lady Comp.

This device is super easy to use — according to the manufacturer, it only requires 30 seconds of your time each day. When you wake up, simply use the attached thermometer to take your temperature. The Lady-Comp will then show if you’re fertile.

One of the reasons why we love this product is because it’s natural to use and doesn’t require any additional purchases of test strips. After you’ve taken your temperature, you’ll see a green or red light. The former indicates your infertile period whereas the red means you are fertile.

Lady Comp does advertise itself as an all-natural birth control, hence the red warning light for fertile periods. However, it’s also a good choice for when the time comes and you’re ready for a baby.


  • Easy to use
  • Works efficiently.
  • All-natural method of birth control.
  • No need for additional accessories.


  • Will only do one thing, namely, track your temperature.
  • The button is small and not easy to navigate
  • Is an expensive device

2. iFertracker Smart Fertility Tracker

Best Wearable Fertility Monitor

To tick the boxes of comfort and efficiency, we’ve chosen the iFertracker fertility monitor. If you feel most comfortable with keeping track of your BBT (Basal Body Temperature), then this device is perfect.

It consists of a small wearable sensor that connects to an app on your smartphone or tablet.

To get the most accurate results using your BBT, you have to track it consistently at the same time everyday. With the iFertracker it will continuously record your temperature during your sleep, which gives you a more accurate reading.

Before you go to bed, attach the tracking device under your armpit and let it do its magic while you sleep. When you wake up, sync the results with the app and remove the sensor.

Inside the app, you’re able to see all of your ovulation cycles. However, users say it’s not the best app on the market. Some TTC (trying to conceive) women said they used a different app for monitoring the data.

Additionally, the sensor also keeps track of your movements and physiological responses during sleep. This means that you’ll be able to analyze the quality of your sleep, which can also affect your fertility (5).


  • Easy to use and will do most of the work for you.
  • Very accurate and efficient.
  • Multi-purpose — tracks both temperature and sleep quality.
  • Comfortable to wear.


  • Requires batteries that may run out quickly.
  • Can leave some sticky residue on the skin when removed.
  • The app has room for improvement.

3. Tempdrop Fertility Tracker

Easiest to Use Fertility Tracker

With the Tempdrop, you’ll be able to better identify your fertile days by tracking the temperature changes you’ll encounter as a result of hormonal fluctuations.

With two ways to wear the Tempdrop, it makes tracking your fertile days more comfortable. You can wear the Tempdrop on the provided strap on your upper arm, so the device rests in your armpit area. Or, if you’d rather, you can wear a high-fitting sports bra to bed and tuck the device without the wearable strap into your bra.

You’ll hold the button on the Tempdrop for five seconds to turn the unit on and download the app from Apple or Google Play. You’ll give your email address and create a username to sign up.

TempDrop Fertility Monitor in Packaging

Then you’ll wear the Tempdrop according to the instructions and go to sleep as you normally would. When you wake up in the morning, remove the unit and put it near your smartphone. All your data will be downloaded to your app, and you’ll get the information you need.


  • It allows you to switch between Fahrenheit and Celsius.
  • The directions that come with the Tempdrop are explained well.
  • It’s easy to use.
  • The battery lasts for up to six months, and it can be replaced.


  • You might need your partner’s help to get the strap hooked onto your arm properly.

4. Mira Fertility Plus Tracking Monitor

Best for Irregular Cycles

Timing is everything when it comes to conceiving, and this tracker from Mira Fertility Plus will not disappoint you.

Mira Fertility Plus is a hand-held monitor with a color screen.

Because this is AI-powered monitor, it provides analysis of your cycle, it will help you pinpoint the exact dates that you’re ovulating. Even when your body decides to mix it all up, you’ll still have the upper hand by providing exact hormone levels of estrogen and luteinizing hormone.

As you place the wand sensor in your urine, it will read and record the hormone levels. Results are automatically transmitted to the Mira app. Here it will identify the trend and relationship of hormones to each other. Then it will provide you with an analysis regarding your fertility period.

The app will monitor when your body switches on all phases of the ovulation cycle. This is particularly good for women with irregular cycles, this sensor is still able to still find a pattern.

That said, it’s essential to follow the instructions to understand exactly how the kit work and what to look for.


  • Fairly easy to take readings.
  • Monitors two hormones- estrogen and luteinizing hormone.
  • 99 percent accurate.
  • Amazing for irregular periods.


  • Can be complicated to understand, so be sure to read the instructions.
  • On the pricey side.

5. Clearblue Touch Screen Fertility Monitor

Best Fertility Monitor for PCOS

Conceiving while affected by PCOS can be difficult, so you want something that’s easy and fast to use. Clearblue is a well-known brand among TTC women, and the company’s fertility monitor is well worth a try.

The monitor itself is very high tech — it features a touch screen that showcases all your fertility data. On top of that, it will save up to six cycles, which you can share with your fertility doctor.

The device tracks the two most important fertility hormones present in your urine — LH and estrogen. Clearblue even states that its results are 97 percent accurate — almost the same as an ultrasound.

Timing is everything, and luckily this monitor will remind you when it’s time to test. This will give you the most reliable results of “peak,” “high,” and “low.”

However, to test, you have to buy test strips separately and dip them in your urine before inserting into the monitor. This does add a bit of extra cost, but for a reliable test, I would say it’s well worth it.

And it’s important to keep in mind that the monitor first needs about one month to analyze and understand your patterns.


  • High-tech.
  • Easy to use.
  • Gives fast and reliable results.
  • Well suited for women with PCOS and irregular cycles.


  • You have to buy separate test strips.
  • Requires at least one month for reliable results.
  • Can get tiring having to pee on a stick every morning.
