If you are trying to understand your fertility or considering IVF, your doctor may recommend an antral follicle count (AFC) test. But what does this test actually measure, and what do the results mean for your chances of pregnancy?
An AFC test helps assess your ovarian reserve by counting small follicles in your ovaries. Understanding your results can help you and your fertility specialist make informed decisions about your reproductive health and treatment options.
What Is Antral Follicle Count (AFC)?
Antral follicle count (AFC) is an ultrasound-based test that estimates the number of small, fluid-filled sacs called antral follicles in your ovaries.
Each follicle contains an immature egg that may develop during your menstrual cycle. By counting these follicles, a fertility specialist can estimate your ovarian reserve, which refers to the quantity of eggs remaining in your ovaries.
The test is commonly performed as part of a fertility assessment, particularly if you:
- Are planning to conceive and want to understand your fertility.
- Are considering IVF or other assisted reproductive treatments.
- Have irregular menstrual cycles.
- Have been diagnosed with polycystic ovary syndrome (PCOS).
- Are considering egg freezing.
- Have experienced difficulty getting pregnant.
- Want to understand how your ovaries may respond to fertility medication.
An AFC test does not directly measure egg quality or guarantee whether you can become pregnant naturally. Instead, it provides your fertility specialist with useful information about your ovarian reserve.
How Is an Antral Follicle Count Test Performed?
An AFC test is a straightforward ultrasound examination that usually takes around 10–20 minutes.
It is generally performed using a transvaginal ultrasound, which allows the specialist to obtain a closer view of your ovaries.
Step-by-step AFC testing process
- Scheduling your ultrasound
Your doctor will usually recommend having the test during the early part of your menstrual cycle, commonly between days 2 and 5.
- Ultrasound examination
A small ultrasound probe is gently inserted into the vagina to examine your ovaries and identify visible antral follicles.
- Counting the follicles
The specialist counts the small follicles in both ovaries, generally measuring approximately 2–10 mm in diameter.
- Reviewing your results
The number of follicles in each ovary is added together to provide your total AFC.
For example:
- Right ovary: 6 antral follicles
- Left ovary: 5 antral follicles
- Total AFC: 11
Your fertility specialist will interpret this result alongside your age, medical history, and other fertility investigations.
Does an AFC test hurt?
Most women experience little to no discomfort during an AFC ultrasound. You may feel slight pressure during the examination, but it is generally well tolerated.
If you feel anxious or uncomfortable, let your healthcare professional know so they can explain each step and help you feel more at ease.
What Is a Normal Antral Follicle Count by Age?
One of the most common questions about AFC testing is: What is a good antral follicle count?
The answer depends on several factors, including your age, ovarian health, and individual medical history.
A higher AFC generally suggests a larger pool of recruitable follicles, while a lower AFC may indicate reduced ovarian reserve.
The following table provides a broad educational overview, not a diagnostic reference range.
| Age group | General interpretation |
| Under 30 | Often higher ovarian reserve |
| 30–34 | Ovarian reserve may begin to decline |
| 35–39 | Further age-related decline is common |
| 40 and above | Lower AFC is increasingly common |
There is no single AFC number that defines normal fertility for every woman. The same result may have different implications depending on your age and clinical circumstances.
What does a low antral follicle count mean?
A low AFC may indicate that fewer follicles are available to respond to ovarian stimulation.
This can sometimes be associated with:
- Reduced ovarian reserve.
- Lower response to IVF stimulation medication.
- Fewer eggs collected during an IVF cycle.
- Age-related changes in ovarian function.
However, a low AFC does not mean you cannot become pregnant. Women with a lower ovarian reserve may still conceive naturally or through fertility treatment.
What does a high antral follicle count mean?
A higher AFC generally indicates a larger number of visible antral follicles.
However, a high count does not automatically mean better egg quality or a higher chance of pregnancy.
Women with polycystic ovary syndrome (PCOS), for example, may have a higher AFC because of the increased number of small follicles in their ovaries.
Your specialist will consider whether the result is consistent with your symptoms, hormone levels, and ultrasound findings.
What Is the Difference Between AFC and AMH?
AFC and AMH are two commonly used tests to assess ovarian reserve.
Although both provide information about the quantity of eggs available, they measure different things.
AMH (Anti-Müllerian Hormone) is a hormone produced by cells surrounding developing eggs in small ovarian follicles. An AMH blood test measures the level of this hormone in your bloodstream.
AFC uses ultrasound imaging to count the visible small follicles in your ovaries.
| Feature | AFC test | AMH test |
| Test type | Ultrasound | Blood test |
| Measures | Visible antral follicles | AMH hormone level |
| Procedure | Pelvic ultrasound | Blood sample |
| Main purpose | Estimate ovarian reserve | Estimate ovarian reserve |
| Cycle timing | Usually early menstrual cycle | Usually any cycle day |
Which test is more accurate?
Neither test is universally better.
AFC and AMH provide complementary information, and fertility specialists may recommend using both to develop a clearer understanding of your ovarian reserve.
For example, if your AMH level and AFC result do not match, your specialist may consider factors such as PCOS, age, hormonal conditions, and ultrasound findings before interpreting the results.
Importantly, neither test measures egg quality directly or predicts natural pregnancy with certainty.
How Does Antral Follicle Count Affect IVF Treatment?
If you are considering in vitro fertilisation (IVF), your AFC result can help your fertility specialist plan your treatment.
IVF is a fertility treatment in which eggs are collected from the ovaries, fertilised with sperm in a laboratory, and the resulting embryo may be transferred into the uterus.
AFC is particularly useful for estimating how your ovaries might respond to fertility medication.
1. Planning ovarian stimulation
During IVF, medication is used to encourage multiple follicles to develop.
Your AFC can help your specialist estimate the likely response and select an appropriate medication protocol.
2. Estimating egg collection
Women with higher AFC may develop more follicles during stimulation, while those with lower AFC may produce fewer eggs.
However, the number of follicles does not necessarily equal the number of mature eggs collected.
3. Understanding the risk of ovarian hyperstimulation
Women with a high AFC, particularly those with PCOS, may have an increased risk of ovarian hyperstimulation syndrome (OHSS).
OHSS is a condition in which the ovaries respond excessively to fertility medication, sometimes causing swelling and fluid accumulation.
Your fertility specialist can adjust the treatment approach and monitoring to help reduce this risk.
4. Supporting personalised IVF planning
Your AFC is only one part of your fertility assessment.
Your specialist may also consider:
- Age and reproductive history.
- AMH hormone levels.
- Other hormone investigations.
- Uterine and ovarian ultrasound findings.
- Previous fertility treatment outcomes.
- Sperm quality and other relevant factors.
At Almond Blossoms, fertility treatment planning can include options such as fertility assessment and IVF treatment and IVF and ICSI treatment where clinically appropriate.
Can You Improve Your Antral Follicle Count?
A common concern after receiving a low AFC result is whether you can increase the number of follicles in your ovaries.
It is important to understand that there is currently no proven lifestyle change, supplement, or treatment that reliably increases your underlying ovarian reserve or reverses age-related egg loss.
However, maintaining good reproductive and general health can support your overall wellbeing while preparing for conception or fertility treatment.
Consider the following:
- Balanced nutrition: Include vegetables, fruits, whole grains, healthy fats, and adequate protein.
- Regular physical activity: Choose exercise that supports your general health without excessive physical strain.
- Healthy sleep habits: Aim for consistent, sufficient sleep.
- Avoid smoking: Smoking is associated with poorer reproductive health.
- Manage existing health conditions: Discuss PCOS, thyroid disorders, and other hormonal concerns with your doctor.
- Seek individual medical guidance: Avoid taking fertility supplements or hormone treatments without consulting your specialist.
Does a low AFC mean poor egg quality?
No. AFC estimates the quantity of recruitable follicles, not the genetic quality of the eggs.
Age is an important factor associated with egg quality, but AFC alone cannot determine whether an egg will fertilise or develop into a healthy embryo.
This distinction is important when discussing your fertility options with a specialist.
When Should You Consider an AFC Test in Dubai?
You may benefit from discussing an AFC assessment with a fertility specialist if:
- You have been trying to conceive without success.
- You are over 35 and planning a pregnancy.
- You have irregular periods or suspected PCOS.
- You are preparing for IVF treatment.
- You are considering egg freezing.
- You have previously experienced a poor response to IVF medication.
An AFC test is not necessary for everyone. Your doctor will consider your reproductive history, age, and symptoms before recommending fertility investigations.
Understanding your fertility results
Receiving a lower-than-expected AFC result can feel worrying, especially if you are planning a family.
However, one test cannot determine your entire reproductive future. Your fertility specialist can explain what the result means, whether further investigations are appropriate, and which options may be available.
At Almond Blossoms Fertility & Wellbeing Center in Dubai Healthcare City, fertility care combines medical assessment with psychological support. This can help individuals and couples address both the clinical questions and emotional uncertainty that sometimes accompany fertility investigations.

Frequently Asked Questions About Antral Follicle Count
1. What is a good antral follicle count for pregnancy?
There is no single AFC number that guarantees a natural pregnancy. A higher count generally indicates more recruitable follicles, but age, egg quality, sperm health, and other reproductive factors also influence pregnancy chances.
2. Can I get pregnant naturally with a low AFC?
Yes. A low AFC does not mean natural pregnancy is impossible. It mainly provides information about ovarian reserve and possible response to fertility medication. Your specialist can assess your individual circumstances.
3. When is the best time to do an AFC test?
An AFC test is commonly performed between days 2 and 5 of your menstrual cycle, when small antral follicles can be assessed during the early follicular phase. Your specialist will advise the most suitable timing.
4. Is AFC better than AMH for measuring ovarian reserve?
Both tests are useful. AFC uses ultrasound to count visible follicles, while AMH measures a hormone in your blood. They provide complementary information and may be used together.
5. Does a high AFC mean better egg quality?
No. A high AFC indicates a greater number of visible small follicles, not necessarily better-quality eggs. Several factors influence egg quality, particularly age.
