Mastering Fertility: The Ultimate Guide to Ovulation Tests for Precision Conception

Many couples want a baby, but pregnancy is only possible during the woman’s fertile days. To find out the best time when the woman is ready to conceive, the couple have to look closer at the woman’s body. Nowadays, there are many helpers, such as the ovulation test (ovulation test), which allows the woman to narrow down the fertile days and thus make her wish to have children come true.

How does an ovulation test work?

An ovulation test is very similar to a pregnancy test. However, with an ovulation test, the average cycle length must first be determined to determine the timing of the start of the test. The cycle length is calculated: 17 days are subtracted from the cycle length (e.g. 28 days) (result: eleven). So you start the test on the eleventh day.

 The test stick must come into contact with the woman’s urine up to the mark. Depending on the test, the contact should last up to ten seconds. It is up to the woman whether the test tip is wetted directly with the urine stream or the urine is first collected in a clean cup.


Classic ovulation test

The “classic” ovulation test has a control and test strips on the display. The control strip becomes visible when the test stick comes into contact with the urine. Depending on the concentration of the so-called luteinizing hormone (LH), the test strip changes colour within five to ten minutes.

If the test strip is just as discoloured as the control strip, the hormone concentration is very high, and the woman will ovulate in the next two days. If, on the other hand, it is only slightly discoloured or not visible at all, ovulation is not imminent and further tests to determine ovulation are necessary.

Digital ovulation test

The digital ovulation test works just like the “classic” ovulation test, but the result is not displayed in the form of lines but digitally. The result is usually indicated by symbols such as a smiley.

It is advisable to carry out the ovulation test daily and always simultaneously until a hormone increase in the urine is noted. If the ovulation test is positive, no further tests need to be carried out because the best time for conception has already been determined.

If the ovulation tests are always negative, the gynaecologist must determine possible causes.


fertility monitor

The LH tests are the most common ovulation tests to determine when ovulation is imminent. There is also the fertility monitor, which, in addition to the two most fertile days, also shows fewer fertile days during which pregnancy can occur. These small computers also work with LH test strips and urine.


Alternative to the ovulation test: the menstrual calendar

Another tool for calculating ovulation is the menstrual calendar, also known as the ovulation calendar. For this purpose, the menstrual days are marked in the calendar for at least six months.

After that, you can limit the fertile days by calculating the shortest cycle (e.g. 28 days) and subtracting 21 days (result: 7). The first possible fertile day is the seventh day of the monthly cycle. Incidentally, a monthly cycle ends with the first day of menstruation, and the same also begins the new cycle.

To find the last possible day of the fertile period, take the most extended cycle (e.g. 31 days) and subtract eight days (result: 23). The last fertile day would be the 23rd day of the monthly cycle. In this example, the fertile days would be between the 7th and 23rd day of the menstrual cycle.

The temperature method

Another method for calculating ovulation is the temperature method. Every morning, the waking temperature (basalt temperature) is measured with a thermometer and noted on a calendar. At the end of a cycle, the entered temperatures are evaluated.

As soon as the temperature rises by 0.3 to 0.4 °C and remains elevated until the period’s onset, ovulation occurs. This method suits women with a regular menstrual cycle, but the evaluation requires a little experience.

Incidentally, the ovulation calculation using the temperature method makes it easier to determine the infertile days because pregnancy is rather unlikely after the temperature rise – which takes place after ovulation.

There are now also special computers with a highly sensitive thermometer that precisely measures the temperature, registers, and evaluates the most minor differences. After a few months, the computer can determine a trend and predict future fertile days.
