Monitor your menstrual cycle with 99.3% accuracy.
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. However, the timing of ovulation can vary from cycle to cycle.

If you want to prevent pregnancy naturally without subjecting your body to artificial methods, or if you want to maximize your chances of becoming pregnant, this fertility computer is perfect for you. Lady-Comp is the intelligent fertility monitor — a next-generation computer that learns, analyzes and indicates infertile days with 99.3% accuracy, without hormones or side-effects.

Why choose Lady-Comp ovulation calculators?

Every Lady-Comp is programmed with decades worth of natural family planning research data, contains a database of more than 1 million cycles and uses bio-mathematical forecasting calculations as well as the very latest computer programming. It is a personal fertility monitor which learns and adjusts to your individual cycle, accommodating most cycle irregularities and varying cycle lengths. Lady-Comp is a one-time purchase without any recurring costs. Several clinical studies confirm its 99.3% accuracy.


Wake up - Measure - Done:

Lady-Comp makes tracking your cycle easy.  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 temperature and menstrual cycle data. 
It monitors your daily status of fertility and will alert you on the days when intercourse may lead to pregnancy, including the day you ovulate – and the five days before ovulation.

As easy as 1, 2, 3!

  1. Take your temperature each morning.
  2. Enter M on the days you are menstruating.
  3. View your fertility for the day.

The Program

The ovulation computers are programmed to accurately determine and display the time of ovulation in the female body. Ovulation causes a slight, but noticeable rise in body temperature. When you measure your temperature with the sensor every morning before you get up, the fertility computer evaluates the data and quickly recognizes your individual fertility pattern.

If you are fertile, the computer will display a red light. If you are infertile, the computer will show you a green light. If the device needs more information, the computer will show you a yellow light.  The fertility indicator is 99.3% reliable and valid for the next 24 hours.
