A fertility monitor is a device that tracks data such as your basal body temperature and fertility hormone levels in your urine, saliva, or cervical fluid so you can learn more about your cycle, predict ovulation, and identify your fertile window. If you want to conceive, this information can help you to pinpoint the best time for intercourse or insemination.
Fertility monitors can predict ovulation by measuring basal body temperature or hormone levels in urine, saliva, and vaginal fluids. Some monitors connect to an app while others store or display data on a touchscreen device.
Types of fertility monitors include:
- Wearables. You can wear these devices in your vagina or on your arm or wrist to measure your basal temperature or cervical fluid. You may wear them while you sleep or use the device at a specific time each day.
- Digital monitors. These handheld devices use urine testing wands to test for hormone levels. The devices display the results on a touchscreen or an app.

To select the best fertility monitor, there are several factors to consider. Decide if you want to test your temperature, hormone levels, or vaginal fluid. From here, you can decide which type of device you want to use. For example, you may use a wearable or thermometer to take your temperature.
Consider your lifestyle and schedule if the test requires you to test at a specific time or window of time. Some monitors require daily tests while others prompt you to test on certain days of the month. Factor in the cost of the device and testing strips, which can add up over time.
You can also decide how detailed you prefer your data to be and if you want to use an app. If you have irregular cycles or any health condition, select a suitable device for your needs. Check out customer reviews if you have a specific concern.
The accuracy of fertility monitors depends on factors such as correct use, quality, and even the length of your cycle. Some monitors are up to 99 percent accurate. Tracking devices may become more accurate after they have accumulated data over several weeks or months.
If you are under the age of 35 and have been trying to conceive for a year or longer, make an appointment to see a fertility doctor. If you are over the age of 35, make an appointment after 6 months of trying to conceive without success. If you are over the age of 40, see a fertility doctor after 3 months of trying to conceive or as soon as possible. A fertility doctor can perform a thorough evaluation that involves hormonal tests, blood work, physical exam, and an ultrasound. Understanding your body and risk factors is helpful and your doctor may suggest interventions or treatments to best address your needs.
Do fertility monitors work?
Fertility monitors are an effective way to measure your temperature and hormone levels to predict ovulation and peak fertility. However, they do not guarantee that you will conceive. Fertility monitors tend to provide more reliable information for women with regular menstrual cycles. If you have irregular or unpredictable cycles, fertility monitors may allow you to better understand your cycle, but you should still review your findings with a healthcare professional.
How much do fertility monitors cost?
Basic fertility monitors such as thermometers may cost around $50 while many devices cost several hundred dollars. Some monitors require you to purchase additional testing strips, which can cost up to $100 every few weeks.
Are they covered by insurance?
You may be able to use your insurance plan, flexible spending account (FSA), or health savings account (HSA) to cover the cost of fertility monitors.
Fertility monitors can help you to track your menstrual cycle to predict ovulation and fertility. This information can help you determine the best time for intercourse if you want to conceive. Most devices are easy to use and provide valuable insights into your menstrual cycle and fertility periods.
However, remember that fertility monitors are not 100 percent accurate or foolproof, nor do they guarantee conception. Furthermore, they are not intended to prevent pregnancy.
