Ovulation Tests

Ovulation is the point during the menstrual cycle when a mature egg is released from the ovary. It is an essential step for both natural and assisted conception, so it is important to know if and when it is happening. If you want to conceive using your own eggs, you must be able to ovulate, with or without extra help from medication. It is still possible to have a baby with IVF if you are not ovulating, but you will need to use donor eggs. 

Who Should Have Ovulation Tests?

Ovulation tests are often included in fertility assessments. You might want to get your fertility checked if you are planning for the future, ready to try for a baby, or having trouble conceiving. The tests can tell you if there are any issues that might make it harder or prevent you from conceiving naturally. Some women experience problems conceiving because they are not releasing eggs regularly. If this is the case then it may be possible to find out why and address the underlying problem. Alternatively, we may be able to trigger ovulation using medication.

If you need help getting pregnant, then you may have more ovulation tests during your IVF treatment. During the early stages of IVF, you will be given medication to encourage your ovaries to release more mature follicles. Ovulation tests can tell us how well this medication is working and when your eggs are ready to be collected.

What Do Ovulation Tests Involve?

We can use several different kinds of tests to check on ovulation. Some of these tests will check the levels of the hormones that control ovulation. The hormones can be detected in your blood or in a urine sample. Different hormones should rise and fall at different points in your menstrual cycle. Ovulation tests will check that these changes are happening in the right way to trigger the release of a mature egg.

Other types of ovulation tests can look at the way your ovaries are responding to these hormones. We would expect to see a number of developing follicles in each of your ovaries at the beginning of your menstrual cycle. An antral follicle count can be performed to check how many eggs are activated in order to estimate the ovarian reserve (the number of eggs remaining in your ovaries). Some of the activated eggs should then develop into mature follicles that will be released into the fallopian tubes so that they are ready to be fertilised. The process can be visualised with ultrasound to ensure that it is happening as expected.

The tests will usually be timed according to your menstrual cycle as most women will be ovulating about halfway through the cycle. For example, if you have a regular 28-day cycle then you should be ovulating at around day 14. We would then recommend starting the tests a few days before this and repeating them until we get the right results. If you have an irregular cycle, it can be trickier to know when to perform the tests, but your doctor can determine when is the best time.

  • Blood test to measure the levels of progesterone, the hormone that is produced when a mature egg has been released at ovulation
  • Blood test to measure the levels of Anti-Mullerian Hormone (AMH) which can be used to estimate your ovarian reserve, the number of eggs that are available in the ovaries
  • Urine test to measure the levels of other hormones related to ovulation, such as luteinizing hormone (LH), which should rise just before you ovulate
  • Ultrasound scan to monitor the developing follicles in your ovaries so that we can see them maturing, being released and travelling down the fallopian tubes

The results of these tests can tell us whether you are ovulating, when it is happening, and what we can do to help you to get pregnant.

How We Can Help?

Ovulation tests can help us to understand why you may be having trouble conceiving. We also use them to guide your fertility treatment. Our experienced fertility doctors can recommend the ovulation tests you need and tell you when they should be performed. We can ensure that you get the right tests and explain the results in detail. We will also use these results to determine the best course of treatment or to get the timing right for your IVF treatment.

If you are worried about your fertility or you need ovulation tests as part of your IVF treatment, then get in touch to discuss your needs and arrange testing in the UK or overseas.


It shouldn’t take long to get the results of your ovulation tests. You may be able to get your scan results on the same day as your ultrasound, but it can take a little longer for the lab tests to be completed. Your fertility specialist will explain what the results mean for your chances of conceiving naturally of through IVF.

The results of your fertility assessment can determine which treatment options are available to help you to get pregnant. It is important to know if you are ovulating before deciding which approach to take.

If the results show that you are ovulating normally then this means that there must be another explanation for any fertility problems you’ve been experiencing. For example, there may be a blockage in the fallopian tubes that is preventing sperm from reaching the eggs or an issue with the womb lining that is preventing implantation. It may be possible to identify and treat these issues to increase your chances of conceiving naturally or to collect the eggs for IVF.

If the results indicate that there is an issue with ovulation, this could explain why you have been having trouble conceiving naturally. It may be possible to stimulate ovulation using medication, which could enable you to conceive naturally or to produce enough eggs to be used for IVF. However, if your ovaries do not respond to these drugs, it will not be possible for you to conceive using your own eggs. You will need to consider whether you want to use an egg donor.

The results of ovulation tests performed during IVF treatment can ensure that the eggs are collected from your ovaries at the right time. The mature eggs can then be combined with sperm in vitro to enable fertilisation to take place.

Ovulation Tests FAQs

Ovulation is when a mature egg that is ready to be fertilised is released from the ovary. It happens in response to the hormones that control the menstrual cycle. Several eggs will usually be activated in the ovaries each month, but only one or two of them will become fully mature eggs. The eggs will move into the fallopian tubes where they can be reached by the sperm.

Ovulation tests are the only way to be sure that your ovaries are releasing mature eggs regularly. However, the hormones that control ovulation can cause some changes in your body that you may be able to detect. Your body temperature usually rises slightly when you are ovulating and you may also notice an increase in vaginal secretions. You can also buy over the counter ovulation tests that can detect the hormones responsible for ovulation in your urine. However, without a complete fertility assessment it is impossible to be sure that your ovaries are responding to these hormones and releasing mature eggs.

A number of different hormones are involved in ovulation. Ovulation tests may measure the level of progesterone in your blood or the amount of luteinizing hormone (LH) in your urine. Both of these hormones peak around the time a mature egg is released. Another hormone test that your doctor might recommend can measure the level of Anti-Mullerian Hormone (AMH) in your blood. The AMH level remains steady throughout the menstrual cycle and it can be used to estimate the ovarian reserve.

The term ovarian reserve is used to describe the number of eggs that are present in the ovaries. Women produce all of their eggs while they are still in the womb. Many of the eggs are lost before a woman is born. The number of eggs continues to decline until the ovaries stop responding to the hormones that usually trigger ovulation. Most of the eggs will be lost without becoming mature eggs that can be fertilised. The size of the ovarian reserve can be estimated indirectly by measuring the amount of AMH present in the bloodstream. A higher ovarian reserve indicates that there are more eggs available so the chances of conceiving successfully are higher (with or without IVF).

At the time they are born, most women will have about a million immature eggs in their ovaries. Most of these eggs will be lost before a woman reaches puberty. When a woman starts menstruating, she will usually have about 300,000 eggs left in her ovaries. Only a small number of these will mature in response to the ovulation hormones. The average woman will release between 300 and 400 eggs during her reproductive life. However, the other eggs don’t all remain in the ovaries as they will be lost over time. The eggs also become less responsive to ovulation hormones with age, so fewer follicles will mature and be available for fertilisation or IVF treatment.

Ultrasound scans can be used as ovulation tests because they can reveal the developing eggs inside the ovaries. It is possible to count the number of immature follicles that have been activated or to track the mature follicles as they leave the ovary. The scan will be performed as a trans-vaginal ultrasound. The ultrasound probe will be inserted into the vagina so that it can produce clear pictures of the ovaries. Having an internal scan is completely safe and while it can be a bit uncomfortable, it shouldn’t hurt.

If the ovulation tests show that you aren’t ovulating naturally, it may still be possible to use medication to trigger the release of mature eggs. However, if this doesn’t work it won’t be possible for you to conceive a baby without using an egg donor. Even if you are ovulating, you may still need to use a donor as the quality of the eggs can also affect your chances of getting pregnant. If you decide to use an egg donor, you may be able to carry the baby yourself as the embryo can be transferred into your womb during the IVF procedure.

Ovulation tests are usually recommended as part of a full fertility assessment before you start treatment. It is essential to know whether you are ovulating before deciding on the right treatment approach. The results can reveal whether you will need IVF treatment or an egg donor in order to conceive. Some women also choose to have a fertility check up including ovulation so that they can make informed decisions about when to start a family or whether to freeze their eggs for future use.

Ovulation tests such as follicle tracking scans may be performed during IVF treatment for a couple of important reasons. Firstly, the tests can confirm that your ovaries are responding to the medication that is used to stimulate the release of mature eggs. Secondly, an ultrasound scan can be used to check that the mature eggs are ready to be collected and used for IVF.

Ovulation tests are very safe. You might need to provide a urine sample or have a small amount of blood taken for testing. Ultrasound scans can also be performed to check that you are ovulating. None of these tests are likely to cause any side effects.
