Lady-Comp is very easy to use

Based on your morning temperature, taken orally, the fertility computer determines your fertile days and shows when you are ovulating by recording, analyzing and storing your menstrual cycle data.

It monitors your daily status of fertility and will inform you on the days when you can get pregnant, on the day you ovulate – and the five days before ovulation.

No hormones: No side effects

There are six days in every cycle when a woman can get pregnant: five days before ovulation and on the day she ovulates. With Lady-Comp, you don’t have to take artificial hormones (according to World Health Organisation contraception pills are group 1 carcinogen) or use mechanical and invasive coils. If you would like to read more about the full list of side effects (cancer, infertility, depression) related with taking of hormonal pills or using IUD (coil) and why they also act in anty-nidation way, by creating a hostile endometrium for a newly conceived embryo - you can find it here: Why do birth control pills and IUDs (coils) act in anti-implantation way for the embryo?

You don’t have to suppress your normal body functions to be yourself.

Easy to Use-30 seconds/day

First of all the temperature is taken and then information about the menstrual dates is requested. This information is evaluated and is compared with more then 700.000 cycles. Next, a diagnosis is made regarding the fertility of the next 24 hours (and the following six days). 

The reliability of this diagnosis has been confirmed in many clinical tests.

All you need to do is press one button a day and to take your temperature orally with the computer’s thermal sensor. The time required each day is only 30 seconds/day.

LadyComp is not only a safe & reliable but also quick and easy to operate.

Better every time

In the beginning, you should take your wake-up temperature as regularly as possible because the more information the computer collects, the easier it is to narrow down the number of fertile (red) days. The computer is safe from the first measurement on. The more data you give the computer the more the computer knows about you.

99.3 percent effective – clinically proven reliability

The fertility computer takes your basal body temperature (BBT) every morning when you wake up with the most advanced temperature sensor (1/100 degrees accurate). It then automatically compares it with its bio-mathematical forecasting software and stored information of all available family planning research. 

It also automatically compares it to hundreds of thousands of cycles of other women to accurately determine, analyze and display your individual cycle. This is why the intelligent fertility computer is one of the most effective fertility monitors in the world. It is 99.3% effective right from the start. A Pearl Index of 0.7 means that this 100-percent natural method is 99.3 percent safe and effective. Lady-Comp supports your natural family planning goals like no other.
