Many couples want a baby, but pregnancy is only possible during the woman's fertile days. In order to find the best possible date of conception, the couples have to deal more closely with the woman's body. There are nowadays many helpers such as the Ovulationstest (ovulation test), which allows a narrowing of the fertile days of the woman and thus make the desire to have children come true.
How does an ovulation test work?
An ovulation test is very similar in use to a pregnancy test. However, in an ovulation test, the average cycle length must first be determined to determine the time of the start of the test. The calculation of the cycle length is as follows: 17 days are deducted from the cycle length (for example 28 days) (result: eleven). So you start on the eleventh day with the test.
The test stick must come in contact with the urine of the woman until it is marked. 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 collected only in a clean cup.
Classic ovulation test
The "classic" ovulation test has a control strip and a test strip in the display. The control strip will be visible as soon as the test stick has contact with the urine. The test strip will discolour within five to ten minutes depending on the concentration of the so-called luteinizing hormone (LH).
If the test strip is as discolored as the control strip, the hormone concentration is very high and the ovulation of the woman takes place in the next two days. If, on the other hand, it is only slightly discolored or not at all visible, ovulation is not yet imminent and further ovulation testing is 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. Mostly the result is indicated by symbols like a smiley face.
It is recommended to perform the ovulation test daily and always at the same time until there is a hormone increase in the urine. If the ovulation test is positive, you do not need to do any more tests because the best time to conceive has already been determined.
If the ovulation tests are always negative, the gynecologist must determine possible causes.
The LH tests are the most common ovulation tests for determining the upcoming ovulation. In addition, there is the fertility monitor, which indicates not only the two most fertile days but also less fertile days, in which it can quite well come to a pregnancy. These small computers also work with LH test strips and urine.
Alternative to ovulation test: The menstruation calendar
Another tool for ovulation calculation is the menstrual calendar, also called ovulation calendar. For this, the menstruation days are marked in the calendar for at least six months.
Then one can limit the fertile days mathematically insofar as one selects the shortest cycle (for example 28 days) and subtracts 21 days (result: 7). The first possible fertile day would be the seventh day of the monthly cycle. Incidentally, one menstrual cycle ends with the first day of the menstrual period, and the same begins with the new cycle.
To find out the last possible day of fertile days, take the longest cycle (for example, 31 days) and subtract 8 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 the 23rd day of the monthly cycle.
The temperature method
Another method for ovulation calculation is the temperature method. Each morning, the warm-up temperature (basal temperature) is measured with a thermometer and recorded in a calendar. At the end of a cycle, the temperatures entered are evaluated.
As soon as the temperature rises by 0.3 to 0.4 ° C and remains elevated until the onset of the period, ovulation has taken place. This method is suitable for women with a regular cycle, however, the evaluation requires a little experience.
By the way, ovulation calculation using the temperature method makes it possible to determine the infertile days, because pregnancy is unlikely after the temperature rises - which occurs after ovulation.
Meanwhile, there are also special computers with a highly sensitive thermometer that measures the temperature very accurately and registers and evaluates the smallest differences. After a few months, the computer can detect a trend and predict the upcoming fertile days.
