Understanding Your Antral Follicle Count (AFC)
What is AFC?
Antral Follicle Count (AFC) is a key fertility test that measures the number of small follicles in your ovaries using ultrasound.
These follicles are fluid-filled sacs that each contain an immature egg. By counting them, we can estimate your ovarian reserve — the number of eggs you may have remaining.
AFC is one of the most accurate ways to assess your fertility potential and is often used alongside AMH for a complete picture.
Why is AFC Important?
AFC provides valuable, real-time insight into how your ovaries are functioning.
AFC helps us to:
• Estimate your ovarian reserve (egg quantity)
• Predict how your ovaries may respond to IVF stimulation
• Guide treatment planning and medication dosing
• Identify conditions such as polycystic ovary syndrome (PCOS)
• Gain an overview of ovarian health by measuring ovarian volume and general appearance
AFC does not tell us:
• Egg quality
• Your ability to conceive naturally
• Your exact chances of pregnancy
Like AMH, AFC is one piece of the fertility puzzle — but an important one.
How is an AFC Scan Performed?
An AFC scan is a simple, safe ultrasound procedure:
• Performed via a transvaginal ultrasound
• Takes approximately 10–15 minutes
• Best done at the start of your menstrual cycle
• No special preparation required
During the scan, a specialist counts the visible follicles in each ovary to give your total AFC.
Understanding Your AFC Results
Your AFC is reported as a total number of follicles across both ovaries. While ranges vary slightly:
• Higher AFC: May indicate a higher ovarian reserve or PCOS
• Average AFC: Suggests a typical ovarian reserve for your age
• Lower AFC: Indicates a reduced ovarian reserve
It’s important to remember:
• A low AFC does not mean pregnancy is impossible
• A higher AFC does not guarantee fertility
Understanding a Low AFC
Being told your AFC is low can feel concerning, but it’s important to keep it in perspective. A low AFC means there are fewer visible follicles than expected for your age, which may indicate a reduced ovarian reserve.
Key Things to Know:
• Natural pregnancy is still possible
• Many women with low AFC conceive without treatment
• Timing can be important
• A lower ovarian reserve may mean a shorter fertility window
• IVF response may be reduced
• Fewer eggs may be collected, but success is still achievable
• It helps guide your next steps
• Your results allow us to tailor the most effective treatment plan
AFC & AMH: A Combined Approach
For the most accurate assessment, we combine AFC with AMH testing.
• AFC: Provides a visual count of follicles
• AMH: Reflects hormone levels linked to follicle number
Together, these form the gold standard for assessing ovarian reserve, allowing us to cross-check results and build a clearer picture of your fertility. Find out more about AMH HERE.
Book your fertility assessment to include an AFC scan
Your Fertility Assessment
An AFC scan is part of a comprehensive fertility evaluation designed to give you answers and direction.
Your assessment may include:
• Detailed medical and reproductive history
• Hormone blood tests (including AMH)
• AFC ultrasound scan
• Semen analysis (if applicable)
By combining these, we can:
• Build a complete understanding of your fertility
• Identify any potential challenges early
• Recommend tailored treatment options

Common Questions
Does AFC change over time?
Yes — AFC can vary slightly month to month but generally declines with age.
Is the AFC scan painful?
Most patients find it comfortable, similar to a routine internal scan.
Can AFC predict my chances of pregnancy?
Not directly — it reflects egg quantity, not overall fertility.
Should I have an AFC scan if I’m not trying yet?
Yes — it can provide valuable insight into your fertility timeline and help with future planning.
