Marquette Method is a science-based, research-based, professionally taught modern method of NFP.

The Marquette Method (MM) uses the ClearBlue Easy Fertility Monitor and ClearBlue monitor sticks to measure hormone levels through a woman’s urine to more accurately pinpoint her fertility level for the purposes of trying to achieve or avoid pregnancy. The MM's algorithm which helps women identify their fertile window can be used with one, two or all signs of biological indicators. The algorithm and monitor provide couples with objective indicators of fertility that are unique to the Marquette Method.

How does the monitor work? After day 6 of the cycle, every morning the woman collects a urine specimen and then uses a test stick placed into the monitor until ovulation is identified. The monitor measures estrogen and Luteinizing Hormone (LH) in the urine. The monitor will register a LOW, HIGH, or PEAK reading based on hormone levels. The trigger for a HIGH reading is an increase in estrogen found in the urine, which can happen in the days leading up to ovulation. The trigger for a PEAK reading is a surge in the amount of LH in the urine, as this LH increases dramatically and rapidly when the ovary is about to release an egg through the follicle. Once a PEAK reading occurs on the monitor, no more testing is required for that cycle. A pack of 30 monitor sticks will last for about 3 cycles.

A double-check method of monitoring the LH hormone is use of the Wondfo ovulation stick. These sticks are used only for LH but are less expensive ($18-$21/50 sticks) than the monitor sticks ($38-$45/30). The best level for monitoring ovulation is 25 miu/ml according to recent research (Leiva et al., 2017)--exactly the level that the Wondfo uses! The LH sticks are to be used with another sign of fertility such as mucus observation or with the Marquette Fertility Algorithm (Barron et al., 2018).

Hormone monitoring isn’t the only way to determine fertility when using Marquette Method though. Mucus readings can still be helpful. Observing mucus and temperature are secondary signs of fertility and may not be easy to interpret. Many women track both mucus and monitor readings. 

The additional sign made available through the self-monitoring of female hormones gives women and couples greater confidence in crosschecking various signs of fertility using the algorithm. Again, the MM can be simplified, and users can choose to monitor only one sign—they have the option of using additional signs if desired. An app for the I-Phone and Android are available for use. 


A woman may choose to chart any combination of the various signs of fertility integrated into the algorithm. For example, she may choose to chart all three signs, or simply just the monitor data.

At the end of the day, the most fertile sign(s) observed is recorded. With instruction, identifying fertile or infertile times becomes readily apparent for most couples. Personalized instruction is important for achieving high effectiveness and confidence in determining the fertile and infertile times of the cycle.


The total cost of instruction is $150.00 which covers all visits for the first year. The cost of the introductory session only is $40 per couple.

If the couple wants to schedule a visit after the first year (perhaps after a baby for example) the cost per visit is $35. A receipt can be given for submission to the insurance companies as NFP cost is often re-imbursable.


The greatest benefit of NFP is that users are encouraged to more fully learn and imitate the love of Christ through the practice of NFP—a love that is free, total, faithful, and fruitful!

Benefits of the MM include high effectiveness, enhanced communication, shared responsibility between spouses, and no health risks, among others. The MM users are empowered with several signs for crosschecking fertility, yet MM can be simplified so that only one sign is monitored, depending on couple preference.
