The new Lady-Comp
The best of both worlds: The new Lady-Comp, in a streamlined design, combines all the functions of its predecessors "Lady-Comp" and "Lady-Comp Baby" in one device. This makes it perfect not only for tracking your own cycle and distinguishing fertile from infertile days, but also for actively addressing family planning needs - naturally and with an independently tested accuracy. Thanks to the intelligent algorithm, which is based on your own basal body temperature, 35 years of research, and the evaluated cycles of now more than 500,000 women, the Lady-Comp knows exactly in which cycle phase you are and shows you at a glance whether you are currently fertile or not - from the first measurement on! In addition, the new interface, which has been completely revised and optimized, provides insights into your personal cycle history as well as a menstruation forecast for the next six months. The operation is totally intuitive, which at the same time allows a relaxed introduction to fertility tracking.
Lady-Comp is thus the first gadget to incorporate all the functions of Valley Electronics and their findings of the last 35 years. It is the star among fertility trackers, an expert in fertility tracking and the personal companion on your TTC journey. After all, the desire to have a child is a complex issue and Lady-Comp offers you the perspective to get pregnant without stress and guesswork.
Why a fertility tracker like Lady-Comp is the perfect companion for every woman
The Lady-Comp is based on the methods of Natural Family Planning (NFP) and, as a reliable lifestyle fertility tracker, calculates the fertile and infertile phases of a woman's cycle on the basis of an effective, accurate and very sensitive computer-assisted basal body temperature measurement immediately after waking.
The temperature sensor integrated in the Lady-Comp allows particularly accurate measurements. This distinguishes Lady-Comp fr om analog NFP methods, wh ere a separate basal thermometer is required, and it is up to the user to decide which thermometer to use, without a guarantee that the thermometer used meets the necessary standards. As a result, there are possible measurement inaccuracies and rounding errors from the thermometer itself or when manually inputting the data to the app. These types of errors can lead to an unintended pregnancy or even the failure of a hoped-for pregnancy.
Through a self-learning algorithm based on scientific research, 10 million cycles of experience from now more than 500,000 users and sophisticated technology, Valley Electronics products offer the highest quality, accuracy, and reliability for cycle monitoring. Additionally, the algorithm can tolerate the occasional outlier readings that may be due to stress, alcohol consumption, or lack of sleep.
Studies supported by Valley Electronics since 1992 show that the learning algorithm distinguishes fertile from infertile phases with accuracy.
You can start using your Lady-Comp at any time. After only 60 seconds in the morning, you know your daily fertility status while remaining 100% natural. With your Lady-Comp, all you have to do is: Wake up. Measure. Done!

How Lady-Comp can help you to get to know your cycle
Every woman is unique and so is her cycle: some cycles are longer, some shorter, and the time of ovulation can also vary. The course of the cycle differs not only from woman to woman, but also from cycle to cycle. Lady-Comp creates your very own profile and adjusts the prognosis based on your cycle history and over one million cycles already analyzed.
The biological background
The physiological basis for the measurement of the basal body temperature (BBT), also called waking temperature, is that your body temperature rises slightly around 24 hours after ovulation due to the hormone progesterone and then remains at a constantly high level (about 0.2 °C above the average pre-ovulatory temperature level) until the onset of menstruation. Basal body temperature is used by the Lady-Comp to calculate and confirm when and if you have ovulated. It is measured directly after waking up in the mouth, under the tongue.
- Each woman has only one ovulation per cycle.
- If, in rare cases, two or more ovulations occur, they always take place within 24 hours.
- After ovulation, the egg can be fertilized for a maximum of 18 hours.
- After sexual intercourse, the sperm can move and fertilize in the woman's body for a maximum of 120 hours (= 5 days).
- This means that a pregnancy can only occur on a maximum of six days - five days before ovulation and on the day of ovulation itself.
Hormones and temperatures
The hormones estrogen, progesterone, FSH (follicle stimulating hormone), LH (luteinizing hormone), and testosterone play important roles in your cycle. FSH and LH ensure that the egg (ovum) matures. After ovulation, the egg membrane (follicle) transforms into the corpus luteum and produces the hormone, progesterone, which causes your basal body temperature to rise slightly. Estrogen causes the uterine lining to thicken and produce more cervical mucus.
Lady-Comp uses this as the basis for its calculations and identifies the six days in the cycle during which conception is potentially possible.
Cycle calculation for irregular cycles
Cycle fluctuations are normal and a natural part of the menstrual cycle. Within one year, your cycle fluctuates (on average) up to 7 days. This natural fluctuation has no influence on the accuracy of your Lady-Comp.
Lady-Comp calculates your current fertility status and the course of your cycle based on the daily measurement of your basal body temperature and the length of your past cycles. The calculation is done individually for each person, taking into account the personal variance of the temperature curve before and after ovulation in real time. The learning algorithm checks each individual measurement and ensures that it does not falsify the calculation of your daily fertility status if it detects an abnormal variation. Through this operation, Lady-Comp can provide fertility indicators with a particularly high degree of accuracy.

Lady-Comp - your reliable partner when planning a pregnancy
With Lady-Comp you know every day whether you are fertile or not. With just a short temperature measurement in the morning, you can significantly increase your chances of getting pregnant each cycle. According to a study, 81% of women who tracked their cycle and planned sexual intercourse accordingly were pregnant after 6 months, compared to only 60% of women who did not monitor their cycle during this time1.

These statistical functions of Lady-Comp are a great help in evaluating your data and identifying possible cycle irregularities, such as anovulatory cycles, luteal insufficiency, or hypothyroidism.
Temperature curve display
On Lady-Comp’s display, you can directly see your current cycle curve. Additionally, you can upload your data via the analyzer on our website, print it out, or email it to your physician as needed. This provides valuable information to your gynecologist to learn more about the health of your cycles and identify any possible factors that may be impacting your ability to conceive.
- Possibility to enter the days on which intercourse took place ("SI-entry") so that you can track the planning and probability of pregnancy.
- Display of possible pregnancy as early as 16 days post ovulation and probable pregnancy indicators as early as 18 days. Unlike other planning methods, Lady-Comp does not leave you guessing. It detects the characteristic deviation of the temperature course of your extrapolated normal curves for a pregnancy and shows it to you early and reliably.
- Display of the conception date: When pregnancy has been achieved, you will know exactly on which day sexual intercourse resulted in pregnancy.
- Predicted due date calculation: Since Lady-Comp knows the date of conception, it can calculate the expected date of birth much faster and more precisely than the usual calculation (which starts from the first day of the last menstrual period).
Observation of early pregnancy
Monitoring basal body temperature throughout the first trimester is a good way to monitor this early stage of pregnancy to ensure that temperatures are staying at a sustained higher level.

Lady-Comp - a fertility tracker with tradition
As early as 1983, Dr. Hubertus Rechberg recognized the potential and possibilities of "natural family planning (NFP)" and wanted to make this option available to all women, not only to a small fringe group. Together with experts from the fields of medicine, IT, and design, he developed a fertility tracker that combined a thermosensor and software, thus setting the basis for the smart NFP we know today under the term "FemTech".
More than 35 years have passed since this vision arose. Valley Electronics’ fertility trackers have successfully evaluated over 10 million cycles of more than 500,000 women - with the current Lady-Comp now the 6th generation of fertility trackers available. Due to this experience of the past decades and several scientific studies, it is possible to provide exceptionally accurate information about your cycle.
This is how the algorithm behind the Lady-Comp works
The Fertility Tracker Method (FTM) is based, in part, on the Calculothermal Method and consists of a combination of three elements:
After a learning phase in which Lady-Comp gets to know your unique cycle, the algorithm starts to narrow down your ovulation even more precisely and sets your fertility window to 5 days before the earliest possible date of your ovulation. In order for the algorithm to determine a temperature rise, a sustained characteristic temperature rise after the expected date of ovulation is required. If the algorithm has detected your ovulation by the characteristic rise in basal temperature, it will calculate non-fertile (green) days individually until the next menstruation. At the end of each cycle, the algorithm re-evaluates its predictions from the perspective of the entire previous menstrual cycle. This secondary analysis allows the algorithm to fine-tune the precision of its predictions more and more.
- The recording and learning of new data (the daily basal temperature, the beginning and end of menstruation, as well as the collected historical cycle data) by a fertility tracker.
- The statistically significant evaluation of the post-ovulation temperature rise, with current and historical data from the database, by an algorithm adapted to the female cycle.
- The avoidance of human input and interpretation errors through the combination of hardware (the sensor) and software (the algorithm) in one device (the fertility tracker).

The accuracy of the algorithm used by Lady-Comp was systematically tested as part of a research study; for the study, 107,000 cycles of 5,328 women from Germany and Switzerland were evaluated over a period of ten years. The independently verified result confirms that the algorithm is highly accurate.

It all comes down to a few degrees
Lady-Comp uses a very sensitive sensor to measure basal body temperature. The unique feature of this sensor is that it waits until the final average temperature has been measured (see figure). It can take about 60 seconds for the Lady-Comp to record your individual temperature. The sensor warms up until it reaches the final temperature value and only then is this value stored. Commercial thermometers have a fast measurement speed because they extrapolate the rising curve, and the final temperature value is estimated.
The Lady-Comp waits until the final temperature value has stabilized to obtain a reliable result. If the temperature drops again (for example, due to breathing, which allows cold air to enter the mouth during measurement), this value is not taken until it rises again and stabilizes. This method ensures a temperature measurement that is as precise as possible.
In a field study in collaboration with the University of Sassari / Italy, it was tested on the basis of 30 cycles whether it is possible to determine ovulation on the basis of the basal body temperature. Different clinical methods of measurement were compared: ultrasound, testing of luteinizing hormone (LH) in the urine and testing the level of progesterone in the blood. Of the 30 cycles evaluated, 26 cycles (86%) ovulated and 4 cycles failed to ovulate; 3 of the 26 cycles showed LH deficiency. In comparison, of the BabyComp data evaluated, 24 cases (80%) were ovulatory, 4 were not ovulatory, and 2 were not interpreted. 3 showed LH deficiency.

Other features include:
- The prognosis of ovulation up to 6 days in advance - perfect for planning.
- Recording and documentation of ovulation which is narrowed down by incorporating data from previous cycles.
- You can indicate when you had sexual intercourse in the planning phase when TTC. Lady-Comp directly evaluates in how many cycles this actually took place during the fertile phase.
- If there is an insufficiency of the corpus luteum or if ovulation does not occur, Lady-Comp will indicate this; this is important information if you are having trouble conceiving.
- The Lady-Comp shows you within 4-5 days if a possible pregnancy is suspected.
- A probable pregnancy is indicated from the 18th day after successful fertilization.
- The Lady-Comp knows the date of conception and can therefore very accurately calculate the expected due date and show your week of pregnancy.

Worth knowing about the menstrual cycle
The female menstrual cycle begins with the onset of menstruation (day 1) and ends with the day before the next menstruation. The entire cycle lasts between 26 and 29 days on average for most women, but shorter and longer cycles are also normal. Many women are unaware of what exactly happens in the body during this period. During the menstrual cycle, the amount of hormones in the body changes, possibly affecting the skin and mood. In addition to the processes that take place in the body, we would also like to inform you about external factors that can influence you and your menstrual cycle.
NFP Natural Family Planning with Method
Enjoy your life naturally!
You may have heard that there are also natural methods to plan conception. The natural family planning, short NFP, is such a method. With the NFP method, you watch your body very closely to determine when you are ovulating and when you are fertile based on the signs it sends you during your cycle. The beauty of this method is not only that you can calculate relatively accurately when your fertile and infertile phases are, but you also learn a lot about your body. Many women who use NFP report that they have only found themselves again by dealing with their individual female rhythm. Are you curious?

Discover our tips for getting pregnant!
Surely you already know the answer to the question "How to get pregnant": A sperm cell meets an egg cell and fertilizes it. Afterwards, the fertilized egg cell only has to implant in the uterus and a baby will grow in your belly. However, for many couples it is often not as simple as it looks in theory. In many cases, our everyday lives and our fast-paced times make it difficult for us to find enough time for togetherness at all. Long commutes to work, different work schedules or shift work, plus sports or other hobbies, and the time in which a child could be conceived shrinks to just a few hours a week. It becomes even more difficult when there are already one or more children who also need attention and take up some of the precious time. But that is exactly what matters: Time for two without pressure and stress. Time for love. And then also at exactly the right time.
