Frequently asked questions

Yes. If your reading is influenced by a bad night or by drinking large amounts of alcohol (omitting a reading once in a while isn't a problem), this doesn't mean that the indicator becomes unreliable. Depending on the phase of your cycle, Ladycomp will react accordingly. Either the reading will be recognized and ignored as an exception, or the device will show a yellow or red light on the next day to be on the safe side

Yes you can upgrade your Ladycomp anytime with our special planning software.
Lady-Comp Baby assists with family planning and reduced fertility. It is not only highly accurate in forecasting your most fertile days, it also registers if you don’t ovulate or if you have a hormonal imbalance (CLI). Polls taken among our customers showed that 75% of women who were unintentionally childless before, finally became pregnant with the help of Lady-Comp Baby.

Yes, ladycomp comes with an integrated, rechargeable battery and a separated power plug. This way you can even use the device when you go camping. You can use the device continuously for about two months before having to recharge the battery.

No. Ladycomp is protected against power failures and voltage fluctuations. When power is shut off, all information remains stored permanently in the device's memory. Even the time, date and year information will continue to count indefinitely without any direct or battery power. Neither can the information be deleted by mistake, e.g. by children playing with the device.

Of course. Young girls and women usually want an especially safe method of contraception. And - provided the user sticks to the rules and has sexual intercourse only on "green" days Ladycomp provides this safety.

No: An increased temperature due to some illness will cause the device to indicate "F". On those days, the fertility indicator will be yellow. The best thing is not to take your temperature while you are sick. After that, you can continue taking your temperature as usual.

Yes. You can start using the device right after unpacking it. The shipment includes the correct power adapter for your country.

Yes, the computer accounts for the sperm's maximum life expectancy of five days for its indication of Fertile or Infertile periods.

Very well. You can simply reset the clock to the local time of your destination and continue to measure as usual. By the way, carrying the device with you on air travels does not involve a problem, whether you have it in your suitcase or in your hand luggage.

Of course, this depends on the product you compare it with. These may be some of the differences: Ladycomp provide an extremely high safety level of 99.3 - 99.4%. Ladycomp is characterized by high quality and durability (remember our service warranty). Ladycomp is equipped with pre-stored information from 900,000 cycles and a sophisticated measuring system, which does not permit any measurement errors. Wrong application resulting in reduced reliability is practically impossible. Taking your temperature takes no longer than approx. 30 seconds. Taking your temperature is possible within a period of six hours. Even shift workers can easily use the product. To change the measuring period all you have to do is set the alarm clock accordingly, even to a different time each day, if required. This way you can also sleep in when you want to. No need to adjust to the device - Ladycomp does the job for you. Ladycomp can be used fully independently from the duration of your cycles. There is no limit for the length of your cycles. It's a one-time purchase without any follow-up costs. Customers can count on personal support at any time. Even years after the purchase, you can get back to us with any questions you may have.

Typically about 3-4 days.

With a Pearl Index of 0.7, Ladycomp is as safe as the pill on "green" days. This has been confirmed by a number of independent studies. Most importantly, this Pearl Index is not some hypothetical assumption but the result of several manufacturer-independent studies. The most comprehensive of these studies was done by the Women's University Clinic of Düsseldorf, Germany, on more than 650 women.

Yes. The basic rule for natural contraception is that a woman should have had at least five continuous hours of sleep before taking her basal temperature. However, this rule basically applies to the total number of hours, so if a woman had only four hours of sleep because she didn't go to bed until 2 a.m. and had to get up as early as 6 a.m., she should not take her temperature on that day. This won't cause any problem. Ladycomp was designed to make up for omitted readings automatically, as long as omitting isn't the rule.
What if a woman has had five hours of sleep, but not five continuous hours, because she had to feed her baby in the middle of that period? Normally, taking your temperature is safe even then. A great number of customers are in that situation and get on well with it. However, there is no general answer to that question. It always depends on your specific case. Basically, there are these types of scenarios:
- You had to get up before your normal waking time, but within the measuring period (i.e. up to 3 hours before your waking time; period indicated by the thermometer symbol). In that case, simply take your temperature immediately.
- If you have slept for a few hours and your baby wakes up BEFORE the measuring period, there should be enough time left to go back to sleep after taking care of the baby. In that case you should have been sleeping for at least another hour before taking your temperature.
It might be a good idea to organize things in a way you don't have to get up at all (e.g. have your baby in your bedroom and keep all necessary items at hand).
- If you really stay up all night once in a while, you can omit one reading without any problem. There is no reason to be afraid of a reduced level of safety. A high number of reading errors will simply result in a slightly reduced green-light phase, which will gradually return to normal later. Typically, users quickly develop their own sense of when measuring is necessary and when it can be omitted. If at some point you should be unsure anyway, we will always be there to help you.

Since the concept of natural contraception is based on recognizing the moment of ovulation, it makes sense to start using the device once you are ovulating again. This means that you can begin using the device once you've had your first new menstruation.

Yes, in fact the new Chip III generation of Ladycomp was designed especially for that type of women. Thanks to its very long measuring period of six hours, women who have to get up several times a night (e.g. mothers of babies or toddlers) can almost always take their temperature, either at their scheduled waking time or directly at night before taking care of the child (since reading takes only 30 seconds, this should not be a problem). I you are a shift worker or want to sleep in, you can change the measuring period at any time within a cycle by simply setting the alarm clock accordingly. That way you can take your temperature at 7 a.m. on one day and at 2 p.m. on the next, provided you had your sleep before that. This means that Ladycomp can be customized to meet your requirements on a daily basis.

Yes, even then the device works very reliably. Occasional delays in ovulation or failure to ovulate will cause the device to show "yellow". In fact this helps women to see how their cycles are changing. Even financially, purchasing a Ladycomp will pay off for you. Since our products are extremely durable, you can easily sell Ladycomp to someone else once you don't need it any more.

Yes, Lady-Comp is FDA approved. Yes, Lady-Comp has DEKRA certification (Scope: Processing, Manufacturing and distribution of electronic equipment for natural family planning and natural contraception).

Setting the alarm clock is not necessary for taking your temperature .

Yes. The devices are designed to handle cycles of varying lengths without posing a safety risk. Ladycomp does not even require a minimum or maximum number of days within a cycle to process its readings reliably. Nevertheless, extreme fluctuations might make using the device a little inefficient because it will result in a greatly increased number of "red" days. Fluctuations of several days are no problem at all. However, if some of your cycles are as long as several months, we recommend using natural cycle regulators (herbal preparations). Please consult your gynaecologist for more information.

There is ongoing progress in medicine and technology. Will Ladycomp be outdated in a few years?
No. Since 1986 the device has been steadily enhanced, and major improvements have been made using the latest findings of research. Whenever there is a new Ladycomp generation available on the market, users can have their existing devices upgraded with the latest chip upon request. Your personal readings will not be affected.

You can find pictures of Ladycomp on our homepage. The device is black and white, with mint coloured keys. It is only about 14 cm (5.5") in diameter and it's very flat, with a height of about 3.5 cm (1.4"). The measuring sensor safely rests on the side of the device and has a mint coloured spiral cable (no entangling) plugged into the bottom of the device. Ladycomp weighs about 200 g (7 oz). This way, Ladycomp easily fits on any bedside table and into any handbag.

Not much. Based on the information stored internally, Ladycomp can make up reliably for missing input. Although we do encourage you to take your temperature very regularly in order to determine your fertile period as precisely as possible, omitting some readings does not reduce the product's safety. If you omit some readings due to illness, Ladycomp will soon return to normal afterwards.

The Pearl Index indicates the level of reliability of a given method of contraception. Where 100 women use contraception method X for a period of one year and one of them gets pregnant despite correct application, method X has a Methodic Pearl Index of 1. It is important not to confuse the Methodic Pearl Index with the Application Pearl Index. The Methodic Pearl Index indicates how reliable a given method is if used correctly, while the Application Pearl Index also includes the number of undesired pregnancies due to disregarded rules of application. For Ladycomp this would be the case if a couple had unprotected intercourse despite the device showing the red light. This way there may be differing Pearl Index values for the same contraception method. For Ladycomp the value is as follows: Provided the device's indicators are properly observed, Ladycomp has an excellent Pearl Index of 0.7, which is similar to the Pearl Index of the pill.

As early as the first day of application. This is made possible by the pre-memorized readings from 900,000 cycles.

Right after you receive the device. If you have just stopped taking the contraceptive pill, you can either start using the device immediately or wait until the beginning of your first real menstruation. Maximum safety will always be provided.

Under the tongue.

Ladycomp was developed by Valley Electronics GmbH in Germany with a team of gynecologists, software specialists, electronics experts and designers. Experience with the device in practical use and its proven success in vivo have also made a considerable contribution. The electronic brain, containing knowledge about fertility, and other components are manufactured by leading suppliers from all over the globe. The project was supported by the Federal Ministry for Research and Technology.

Studies comparing normal Ladycomp users with users who were also regarding other features have shown that regarding those other features, such as mucus or intermenstrual pain, did not provide any advantage, but actually produced more insecurity and in some cases even reduced contraceptive safety. In addition, those studies did not show a difference between women experienced in natural family planning and those who had never learned about it. That's why the developers decided not to consider any additional features. In fact, the product's unique reliability of 99.3% can hardly be exceeded.

Yes, normally within one day. If you haven't received a confirmation within 48 hours, please inquire whether the product has been shipped correctly.

This depends on whether you just take a regular painkiller once in a while - that's no problem at all - or whether you take a medicine over an extended period of time. If that is the case, you should ask your doctor or pharmacist whether it has an impact on your body temperature. If so, you should stop taking your temperature during that time; otherwise you can continue measuring as usual.
