Fertility Tracking Technologies: How Do They Work?

By Saheli Plus | February 3, 2025

Fertility tracking is a crucial aspect of family planning, as it plays a vital role in both conception and contraception, giving women control over their fertility and empowering them to make informed reproductive choices.

Fertility tracking is all about determining the fertile window, which is the time during the menstrual cycle when your fertility peaks. Ovulation tracking and finding the fertile window help you decide when you should double up the protection to avoid unnecessary pregnancies or reverse contraception to conceive. While there are proven traditional methods to identify the fertile window, you can leverage the recent technological developments to complement them and make them more accurate.

This article lists fertility tracking technologies and assesses their effectiveness and reliability.

Traditional Fertility Tracking with Fertility Awareness Methods (FAMs)

Traditionally, fertility tracking is done using fertility awareness methods (FAMs). These methods involve monitoring various physiological changes that indicate imminent ovulation and predict the time you will be most fertile.

Fertility tracking traditionally involves three Fertility Awareness Methods (FAMs). They are:

  • Standard Days Method
  • Cervical Mucous Method
  • Temperature Method

While these methods work well under ideal conditions, they require consistency and discipline, making them less reliable. This is where modern digital solutions come in.

Fertility Tracking Technologies

Numerous emerging technologies help identify the fertile window. Some of the technologies that complement fertility awareness methods in ovulation tracking include:

1. Ovulation Predictor Kits (OPKs)

OPKs are self-use, at-home urine test kits used to predict ovulation. Usually, 24 to 36 hours before your ovaries release a mature egg and kickstart the ovulation process, there is an increase in luteinizing hormone (LH). By detecting this hormonal surge, OPKs predict ovulation, helping you determine when you will reach peak fertility during a menstrual cycle.

2. Wearable Fertility Monitors

Wearable fertility monitors are smart wearables that come in various form factors, such as bracelets, rings, or patches. These devices continuously monitor physiological parameters associated with fertility and alert you when they predict ovulation.

3. AI-Powered Fertility Apps

AI-powered fertility apps neither involve sensors nor test kits to predict ovulation. These are simple mobile apps that merely use Artificial Intelligence to process the information input by the user. You must enter your period dates, basal body temperature, and other relevant symptoms into these apps. They use AI algorithms to process these data, learning from individual patterns to forecast fertile windows and ovulation days.

4. Saliva and Urine-based Trackers

Saliva and Urine-based Trackers analyze saliva or urine samples to detect hormonal changes. These changes indicate ovulation. Saliva-based tracker kits contain a microscope slide. To use the kit, you must place a drop of saliva on the slide and let it dry. Estrogen levels usually rise before ovulation. The dried saliva on the slide will display a fern-like pattern under the microscope if the estrogen levels are high. By examining the pattern formed by the hormonal changes, you can predict ovulation.

How Reliable Are These Technologies?

These fertility tracking technologies can significantly improve accuracy in predicting ovulation compared to traditional fertility awareness methods. However, external factors like stress, illness, and irregular cycles can impact results. Combining traditional fertility awareness methods with these tracking technologies can significantly enhance the reliability and accuracy of fertility tracking.

Frequently Asked Questions

1. How do fertility trackers work?

Fertility trackers monitor physiological signs like basal body temperature, cervical mucus, and hormone levels to identify ovulation periods, aiding in conception or contraception planning.

2. How accurate is tracking your fertility?

Fertility tracking accuracy varies; perfect use results in pregnancy rates of fewer than 1–5 per 100 women annually, while typical use sees higher rates.

3. Do fertility tracking apps work?

Fertility tracking apps can enhance menstrual cycle awareness. However, one should not solely rely on them for contraception or conception, as input errors and inconsistent use can lead to inaccuracies. They should be used with other tracking technologies and fertility awareness methods to improve accuracy.

4. What is the best method to track fertility?

Combining methods, such as monitoring basal body temperature, cervical mucous method, and using ovulation predictor kits, offers a more reliable approach to tracking fertility.
