What is the LH surge?

The LH surge is a spike in the amount of luteinizing hormone (LH) in your body. This hormone plays a crucial role in your menstrual cycle. About 24 to 36 hours before ovulation occurs, LH levels reach a peak – this is the LH surge. This surge stimulates the egg to be released from the ovary, ready for the fertilization. So it's actually a signal from your body that the ovulation is coming!

Why is the LH surge important?

Identifying your LH surge is super helpful if you want to get pregnant. Your fertile window is short: about 24 hours after ovulation, the egg can be fertilized. Sperm cells can survive in your body for up to five days, so if you know when your LH surge is, you can plan ahead by having intercourse in the days leading up to and on the day of ovulation itself.

How can you measure the LH surge?

The most common way to measure your LH surge is with an ovulation test. These tests measure the amount of LH in your urine. They work in much the same way as a pregnancy test: you hold the test in your urine stream or dip it in a cup of urine. You usually have to do this for a few days in a row, around the time you expect to ovulate. A positive ovulation test (often recognizable by two clear lines or a smiley face) indicates that your LH surge has been detected and that you will probably ovulate within 24-36 hours.

When do you start testing?

The moment you start ovulation testing depends on the length of your menstrual cycle. If you have a regular 28-day cycle, ovulation usually occurs around day 14. In that case, you can start testing around day 11 of your cycle. If your cycle is irregular, it is best to use the shortest cycle you have had in the past six months. Then start testing 17 days before your next expected period. It can be useful to test twice a day, around noon and in the evening, because the LH peak does not always occur at the same time.

How reliable is an ovulation test?

Ovulation tests are generally very reliable, with an accuracy of at least 99%. However, there are a number of factors that can affect reliability. For example, certain medications, a recent pregnancy test can affect the accuracy of the test. miscarriage or the use of fertility treatments affect the result. Always use tests from the same brand and read the instructions carefully. Also do not test with morning urine, because the LH peak often occurs later in the day.

What if the ovulation test does not indicate an LH surge?

It is possible that an ovulation test does not indicate an LH peak, even though you are ovulating. This can have several causes. Perhaps you ovulated too early or too late tested in your cycle, or your urine was too dilute. It is also possible that you have a short LH peak that you missed. Have you not found an LH peak with ovulation tests for several cycles? Discuss this with your GP or midwife. We are always ready to think along with you about Midwives PuurBegin in Kampen.

Different types of ovulation tests

There are different types of ovulation tests available, each with their own advantages and disadvantages. For example, there are simple strip tests, midstream tests and digital tests. Digital tests often give a clearer result (for example a smiley) and some also measure other hormones, such as estrogen, to determine your fertile days even more accurately. For example, Clearblue offers several types of ovulation tests, including the Connected Ovulation Test System and the Advanced Digital Ovulation Test, both of which measure estrogen and LH.

Alternatives to ovulation tests

In addition to ovulation tests, there are other ways to determine your fertile days. A well-known method is the calendar method, in which you keep track of your menstrual cycle to predict ovulation. However, this method is less reliable, because ovulation can differ per cycle. Measuring your basal body temperature (every morning before you get up) can also give an indication of your ovulation. Your temperature rises slightly after ovulation. The disadvantage of this is that you only know afterwards that your ovulation has taken place.

Tips for using ovulation tests

To maximize the reliability of ovulation tests, we have a few more tips for you:

Test at the same time of day, preferably in the afternoon or evening.
Do not use morning urine.
Don't drink too much before testing, otherwise your urine may be too diluted.
Read the test instructions carefully.
Use tests from the same brand for consistent results.
Start testing early, especially if you have an irregular cycle.

What can you do after finding the LH surge?

If you have a positive ovulation test, it is time to take action! This means that you are about to ovulate and that you are most fertile in the coming days. It is advisable to have intercourse in the 24-48 hours after the LH surge. Sperm cells can survive up to five days, as mentioned before, so it is also good to have intercourse regularly before the LH surge. Try to relax and above all enjoy it together.
