Why does trackle measure the temperature? And why vaginal? What does the temperature have to do with getting pregnant? And why do I have to deal with topics like “cervical mucus"? Are we perhaps exaggerating a bit?

To be honest, no. Measure temperature, but correct.

trackle supports you in the correct use of the so-called “symptothermal method. The trick is that NOT ONLY  the temperature but also other fertility paramerters are observed and included into the calculation- namely the “symptoms" of the “symptothermal method".

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

Before ovulation, your body is busy ripening several ovarian follicles. That’s what the hormone FSH does. All of these growing follicles produce estrogen – and when enough estrogen is in the blood, the hormone LH becomes active and triggers ovulation: the best, most beautiful and most developed of the mature follicles, bursts and sends its egg cell on the journey. 

While the egg cells is on the way, the follicle is closing. It become the yellow body of the ovary and produces progesterone. This hormone causes a characteristic increase in body temperature – this higher temperature persists until the next menstruation begins and a new cycle begins. The risen temperature remains until the next menstruation begins and a new cycle begins.

The symptothermal method uses the changes in cervical mucus and core body temperature to evaluate your cycle and to distinguish between fertile and infertile days. A rise in core body temperature is a sign for ovulation and that you are no longer fertile. If the cervical mucus gets clearer, more spinnable and transparent, you are close to ovulation and you are fertile. After ovulation, when the cervical mucus becomes thick, lumpy or disappears completely, it is a sign that ovulation has happened and you are no longer fertile. 

Every morning before you get up you take your temperature either orally or vaginally and note it down. Throughout the day you observe your cervical mucus and note its composition in the evening. Every evening you compare your temperature and the composition of your cervical mucus to find out whether you have ovulated or are about to ovulate.

According to the principles of the symptothermal method, ovulation has occurred when these two conditions are met:

1) A cervical mucus climax has taken place, in other words: cervical mucus of very good quality (particularly transparent, sticky and pullable) followed by three days of cervical mucus of clearly inferior quality. 

2) A temperature peak has occurred, meaning that the temperature has been higher for at least three following days than the previous six days. The third higher temperature value must be at least 0.2°C higher than the one measured on the previous six days.

A slightly more complicated issue are the infertile days before ovulation. Here the cervical mucus plays an important role: it is a sign for the beginning of fertility. In addition, the last cycles are analysed and the temperature rise is used to calculate when the earliest ovulation happened. Again, the symptothermal method uses a “double check" to safely evaluate your cycle.

To make the observation of the cervical mucus easier, the symptothermal method defines certain abbreviations, which we will explain to you briefly here. 

To be able to realiably tell, when ovulation has occured and what the current cycle status is, temperature values must be properly measured, transmitted and combined with other body observations.

This is done by the trackle system for your:

1. trackle only uses core body temperature from within your body – the so-called surface temperature, i.e. on the wrist, is too easy to influence
2. trackle measures while you sleep. This avoids the error-prone selective measurement in the morning- this contributes to safety
3. trackle transfers your temperature data automatically – no more mistakes, when entering curves, tables and apps
4. trackle calculates your cycle according to the standards of the symptothermal method – well researched and reliable

The trackle sensor uses a high-precision thermometer that accurately records and stores your core body temperature ind hundredths of a second. This is in liene with the requirements of the symptothermal method.

The classic measuring in the moring is difficult: it requires a lot of discipline and a regular rhythm of life to be trule reliable. Measuring in sleep therefore makes your life easier: no matter when you wake up, when your are sleeping, whether, you are disturbed at night or have partied longer in the evening. By measuring your basal body temperature during sleep, the lowest value is definitely recognized. Certainly.

Calculate, count, follow rules, enter values: yes, that is everything you need to do, so that the results are correct. But you do not have to do that yourself, right? There is the clever trackle system. It transfers your data and calculates everything that is necessary for a reliable result.

With trackle monitoring your cycle will be child’s play. Due to the
precise temperature measurement and the sophisticated app you will
always know your cycle status and when you can get pregnant.
