Overview
Ovarian Reserve Testing is one of the most precise and reliable tests suggested for women who wish to get pregnant. Additionally, women over 35 years of age or those with fertility problems are more likely to benefit from this diagnostic tool. The test identifies the number of healthy eggs in a woman and her ability to get pregnant naturally. It is particularly relevant for women who want to delay the pregnancy or undergo some fertility treatment. The test helps assess the chances of getting pregnant and can become a source of fertility treatment options.
This article will help you understand what ovarian reserve testing involves, why it’s important, when to consider it, and how the results can guide fertility planning.
Why is Ovarian Reserve Testing Important?
Female reproduction depends largely on the availability of ovarian reserve, i.e. the number and quality of eggs in the ovaries. With age, the egg count and also the quality lower naturally, thus reducing the chances of conception.
Ovarian reserve testing is the instrument through which women can determine their reproductive timeline. Women are aware that their fertility window gets narrower and shorter as they advance in age. For couples who cannot conceive, that test is the first step to fertility evaluation.
Ovarian reserve testing is one of the most important factors that might influence a doctor's decisions about the patient's future course of treatment. It is especially helpful for patients who are thinking about IVF (In Vitro Fertilisation) or a similar procedure. To put it simply, the test findings provide fertility planning greater knowledge, control, and confidence.
Types of Ovarian Reserve Tests
Fertility experts perform multiple tests to measure ovarian reserve. These tests, by themselves, present different aspects of a woman's reproductive potential.
Type of Ovarian Reserve Tests:
1. AMH (Anti-Müllerian Hormone):
The AMH level is a snapshot of the ovaries' egg supply. In general, a high AMH means a well-kept ovarian reserve, on the other hand, a low level points towards fertility potential.
2. AFC (Antral Follicle Count):
The antral follicle count is a transvaginal ultrasound procedure, where the number of small follicles is counted in both the left and right ovaries. Usually, a higher AFC count is a sign of a more robust reserve.
3. FSH (Follicle Stimulating Hormone):
FSH or Follicle Stimulating Hormone, which is produced by the pituitary gland (a gland in the brain), helps in the development of eggs in the ovary. The blood sample for this test should be taken on the 2nd or 3rd day of the menstrual cycle. A high FSH level may signal a low ovarian reserve.
4. Estradiol Test:
In the same blood sample taken for the FSH test, Estradiol is measured as well. Estradiol is an estrogen type released from mature follicles, primarily by granulosa cells, in the follicular phase of the menstrual cycle. The normal range of Estradiol during the 2nd day of menses is 20-50 pg/ml. Low levels of Estradiol in the early follicular phase are compatible with a good ovarian reserve.
5. Clomiphene Citrate Challenge Test:
The test, which is not widely used, follows the ovaries' response to a drug that induces egg production, thus uncovering the capacity for producing eggs.
6. Transvaginal Ultrasound:
Using sound waves, this test can look at the ovaries and determine their size, the number of follicles, and if any abnormalities are present that might interfere with conception.
Together, these procedures offer a detailed picture of both the number of eggs available and how well the ovaries are working.
When Should You Get Ovarian Reserve Testing?
By determining your ovarian reserve, which refers to the number and the quality of eggs in your ovaries, you take a very important step in setting up your fertility journey. Through this test, your doctor gets a clear picture of how your ovaries are working, and the tests give them directions if you want to get pregnant or just plan ahead.
You should consider ovarian reserve testing in the following situations:
- Difficulty Conceiving: If pregnancy has been your goal for more than a year without success (or six months if you are over 35), it would make sense to do a test to find out if a low egg count is the culprit.
- Planning Pregnancy at an Older Age: A woman in her 30s or later would likely evaluate her reproductive potential first before determining whether or not to postpone getting pregnant.
- History of Ovarian Surgery or Chemotherapy: Both treatment options can harm the ovaries, hence early testing is mandatory.
- Preparing for IVF or Egg Freezing: Ovarian reserve tests used by doctors are the best method for determining how to adapt fertility treatments and which stimulation protocol will work best.
How is Ovarian Reserve Testing Done?
Most, if not all, ovarian reserve tests are straightforward, minimally invasive, and performed in a fertility clinic.
1. Blood Tests
To measure the levels of AMH, FSH, and oestradiol, blood samples are taken. Doctors can determine how well ovaries are working and how many eggs are remaining by looking at the levels of these hormones. The Anti-Müllerian Hormone level in the blood is measured by the AMH test. Although FSH is not a good indicator of how well an ovary is responding to fertility medications, it can be useful when the egg count is extremely low. The test, specifically for FSH and Oestradiol, can be conducted on specific days of the menstrual cycle.
2. Transvaginal Ultrasound
This ultrasound is done during the first days of the menstrual cycle. The doctor can get a good look at the ovaries through this scan and also count the small, developing follicles (AFC). The whole procedure is normal and usually without any pain. On the whole, more antral follicles would usually point to a higher egg count and a better ovarian reserve. Results obtained here lay out the fertile profile very clearly and hence, serve as the guide in further planning and decision-making regarding treatments.
What the Ovarian Reserve Testing Results Mean
Normal ovarian reserve test results vary from test to test and from person to person. Usually such results show that a woman has a proper ovarian reserve and is likely to conceive successfully. Here is a brief explanation of what your numbers may mean:
However, in general, normal results indicate that a woman has a healthy ovarian reserve and a good chance of successful conception. Here’s a simplified explanation of what your numbers may indicate:
- High AMH / High AFC:
Advantages include a large ovarian reserve, which increases the likelihood of a positive response to reproductive therapies.
- Normal AMH / Normal AFC:
This implies that the reproductive system is functioning properly and thus the chance of natural conception is quite high.
- Low AMH / Low AFC:
It denotes the declining ovary reserve and the minimum number of eggs present. It does not necessarily rule out pregnancy, but it does suggest that the process of becoming pregnant may take longer or that medical intervention would be required.
Usually, your doctor will have the results of your test within a week after the test has been done. Depending on ovarian reserve testing and any other fertility tests you may have had, they will decide what treatment is best for you. It is a huge mistake to assume that these results are only a rough estimate of the reproductive potential and do not indicate the ability to conceive naturally.
Limitations of Ovarian Reserve Testing
Even though ovarian reserve testing is very detailed, it still has few limitations that patients need to know:
- Predicts Egg Quantity, Not Quality : The tests indicate the number of eggs available, but not their genetic health or quality.
- Does Not Guarantee Pregnancy : A good ovarian reserve cannot be the only reason for pregnancy since healthy sperm and favorable uterine conditions are also required.
- Variations Between Individuals : Women’s hormone levels can slightly fluctuate throughout the menstrual cycle, depending on the lifestyle, and even the lab standards.
- Age Remains the Key Factor : A good ovarian reserve cannot protect the quality of a woman’s eggs from aging-related decline.
Therefore, a fertility doctor who takes into account not only age but also medical history and lifestyle should always interpret ovarian reserve test results.
Conclusion
Ovarian reserve testing is like a window which shows the woman’s reproductive health and it is an essential instrument for family planning, fertility treatment, and overall well-being. By determining ovarian reserve sooner, women can make the right decisions for their fertility journey.

Early diagnosis and expert medical support are the two factors that give women the freedom to decide what to do with their reproductive future.
Common Questions Asked
What is a good ovarian reserve level?
Typically, normal AMH levels and a good antral follicle count are indicators of a healthy ovarian reserve. Your doctor will let you know what is normal for your age group.
What is the normal range for ovarian reserve testing?
AMH levels from 1.0 to 3.5 ng/mL are mainly regarded as normal; however, the reference values change slightly from one laboratory to another.
When is the best time to take the ovarian reserve test?
AMH can be measured at any time during the menstrual cycle. FSH and Estradiol should be checked on day 2 or 3 of your cycle.
Can I check my ovarian reserve?
Absolutely. A simple blood test and ultrasound, which are usually done by a fertility specialist, are sufficient to evaluate ovarian reserve.
Can stress affect egg quality?
Long term stress, for example, can cause hormonal imbalance and eventually ovulation can be disrupted, so egg quality and fertility can also be affected indirectly.
How many follicles are normal in each ovary?
A normal antral follicle count is usually between 6 and 10 follicles per ovary, however, it may be different depending on age and individual health factors.
