What is the Symptothermal Method?

  • The symptothermal method is a method of natural family planning (NFP). It helps you to understand where exactly you are in your cycle, i.e. whether you can get pregnant or not. To evaluate this, the Symptothermal method uses various fertility indicators, such as the core body temperature and the Zervixschleim, back and evaluates them according to specified calculation criteria in order to cycle to evaluate reliably. The aim is to determine whether or not ovulation has already taken place in the cycle under consideration - i.e. whether fertility can still be assumed or whether the fertile phase has ended.

    Because after the symptothermal evaluation cervical mucus and If the body core temperature is evaluated, there is a "double check". This means that fertile and infertile days can be distinguished much more precisely. The calculation rules of the symptothermal method have been researched and defined by several studies (cf. studies by Freundl G, Frank-Hermann P, Gnoth C et al.).

For whom is the Symptothermal method suitable?

  • With the symptothermal method, all people who have a hormonally unaffected cycle can determine whether and when ovulation has occurred.

How does the Symptothermal method work?

The Symptothermal method is based on the interaction of the hormones estrogen, progesterone, LH and FSH in the body:

Before the ovulation your body is busy letting several egg follicles mature. This is what the hormone FSH does. All of these growing sacs produce estrogen. The hormone estrogen affects Zervixschleim – the closer you get to ovulation, the thinner and more transparent the cervical mucus becomes. The LH hormone becomes active and triggers ovulation: the best, most beautiful and most developed follicle bursts from the mature follicle and sends its ovum on its journey. While the ovum is on the way, the follicle calls it a day. It becomes the corpus luteum and produces progesterone. This hormone causes a characteristic increase in body temperature - this higher temperature remains until the next menstruation begins and a new one cycle begins.

The changes in cervical mucus and core body temperature are used by the symptothermal method to evaluate your cycle and to differentiate between the fertile and infertile days. The increase in core body temperature is a sign that the ovulation has taken place and you are no longer fertile. The cervical mucus - the clearer, more spinny and transparent it becomes - is a sign that ovulation is approaching and that you are fertile. After ovulation when the Zervixschleim thick, lumpy, or "disappears" entirely, it is a sign that ovulation has occurred and you are no longer fertile. 

How do I use the Symptothermal Method?

Every morning before you get up, you take your temperature either orally or vaginally and write it down. During the day you observe yours Zervixschleim and write down its condition in the evening. Every evening you compare the temperature readings and the quality of the cervical mucus to find out if yours ovulation has already taken place or you are about to do so.

You can read below how trackle makes this method easy, safe and suitable for everyday use!

These rules must be observed

According to the rules of the symptothermal method, the ovulation occurs when these two conditions are met:

1) A cervical mucus peak has taken place, i.e Zervixschleim with very good quality (particularly clear, sticky and stretchable) followed by three days of cervical mucus with clearly poorer quality.

2) A high temperature has occurred, i.e. the temperature has been higher for at least three days in a row than the six days before. The third higher temperature value must be at least 0.2°C higher than the six days before.

A slightly more complicated matter are the infertile days before ovulation. At the same time he plays Zervixschleim an important role: it serves as a sign of the beginning of fertility. In addition, the last cycles are analyzed and, based on the temperature rise, it is calculated when the earliest ovulation took place. Again, the Symptothermal method applies "double checking" to cycle evaluate safely.

  • Advantages of the Symptothermal Method

    Observing body symptoms, including temperature, has been proven to work. It is not at all invasive, very meaningful and helps women to get to know their body and its functions better and to make self-responsible decisions. the Sympothermal Method helps you calculate your fertile days, always using a "double check".

  • Disadvantages of the symptothermal method

    The interaction of the different hormones is a miracle - but also not a machine. Different things can throw the system out of balance. And isn't your everyday life pretty packed? Also measure know and feel what your body is doing - not so easy to implement. That's why it's easy to make mistakes when implementing the Symptothermal method - especially if measurements are taken selectively, i.e. only in the morning, and the data is entered or noted down by hand.

  • Reliability of the symptothermal method

    The Symptothermal method has been well researched for many years and its reliability in determining the fertile days has been proven by several studies.

trackle makes the symptothermal method easy

The Sympothermal Method, on the trackle based, combines your body core temperature measured overnight with your information on Zervixschleim. It's very easy - and is essential for safety.
Because in order to be able to say reliably when the ovulation has taken place and what the current cycle status is, temperature values must be correctly measured, correctly transmitted and correctly combined with other body observations. That takes care of that trackle System for you:

trackle only uses body core temperature from inside your body - the so-called surface temperature, for example on the wrist, is too easy to influence. trackle measures while you sleep. This avoids the error-prone spot measurement in the morning - this contributes to safety. trackle transfers your temperature data automatically - no more errors when entering curves, tables and apps. trackle calculates yours cycle according to the standards of the Symptothermal Method – well researched and reliable.

  • Measure body core temperature more precisely

    Of the trackle Sensor uses a high-precision thermometer that records and stores your core body temperature to the hundredth. It is therefore compliant with the requirements of Symptothermal Method – and not even the smallest temperature deviation slips through his fingers.

  • Just in your sleep

    The classic measurement in the morning is difficult: it requires a lot of discipline and a regular rhythm of life to be really reliable. Measuring while you sleep makes your life easier: no matter when you get up, when you sleep, whether you are disturbed at night or whether you party longer in the evening: by measuring your Basaltemperatur in sleep, the lowest value is recognized in any case. Certainly.

  • trackle does the work for you

    Calculating, counting, observing rules, entering values: yes, it has to be so that the results are correct. But you don't have to do that yourself, do you? That's what smart is for trackle-System. It transmits your data and calculates everything that is necessary for a reliable result.
