What is AMH?
Anti-Müllerian Hormone (AMH) is produced by small, developing follicles in your ovaries. These follicles contain immature eggs, and your AMH level helps indicate your ovarian reserve — the number of eggs you may have remaining. AMH naturally declines with age, making it a key marker in understanding your fertility potential.
Why is AMH Important?
AMH gives valuable insight into how your ovaries may function — but it’s only one part of the bigger picture.
AMH helps us to:
• Estimate your ovarian reserve (egg quantity)
• Predict how your ovaries may respond to IVF treatment
• Guide medication dosing for safer, more effective care
• Identify possible conditions such as PCOS
AMH does not tell us:
• Egg quality
• Whether you can conceive naturally
• Your exact chances of pregnancy
• When menopause will occur
That’s why we always assess AMH alongside an ultrasound scan (AFC) and your medical history for a complete and accurate picture.

How is AMH Tested?
Testing your AMH is simple and convenient:
• Quick blood test
• Can be done at any time in your cycle
• No preparation required
You can include this as part of your initial consultation or a full fertility assessment.
Understanding Your AMH Results
AMH levels are reported as a number (pmol/L in the UK). While ranges vary slightly, generally:
• Higher AMH: May indicate a higher ovarian reserve or conditions such as PCOS
• Average AMH: Suggests a typical ovarian reserve for your age
• Lower AMH: Indicates a reduced ovarian reserve
It’s important not to interpret these numbers in isolation. A lower AMH does not mean pregnancy is impossible, and a higher AMH does not guarantee fertility.
Understanding Low AMH
Being told your AMH is low can feel overwhelming — but context is everything.
A low AMH means you may have fewer eggs remaining than expected for your age, but it does not define your ability to conceive.
Key points about low AMH:
• You can still get pregnant naturally – AMH measures quantity, not egg quality or ovulation. Many women with low AMH conceive naturally.
• Timing may be important – A lower ovarian reserve can mean a shorter fertility window. Earlier planning or treatment can help optimise outcomes.
• Response to IVF may be lower – Women with low AMH may produce fewer eggs during IVF, but success is still achievable.
• It informs personalised care – Knowing your AMH helps us tailor your approach, whether that’s trying naturally, IVF, or options like egg freezing.
If your AMH is low, we will:
• Review your full fertility profile, including ultrasound and hormone tests
• Discuss realistic timelines and options
• Create a personalised plan to maximise your chances
You’ll receive clear, compassionate guidance at every step.

AMH & AFC: A More Complete Fertility Picture
To build the most accurate picture of your reproductive potential and ovarian reserve, clinicians assess two key markers: Anti-Müllerian Hormone (AMH) and Antral Follicle Count (AFC).
• AMH (Blood Test): AMH levels generally reflect how many eggs you have remaining.
• AFC (Ultrasound Scan): This is a transvaginal ultrasound performed at the start of your cycle. It measures the number of early-stage (antral) follicles in your ovaries, helping us to estimate your egg supply.
Together, these provide the gold standard assessment of ovarian reserve, allowing us to create a more reliable and personalised plan. Find out more about AFC scans HERE LINK

Common Questions
Can AMH predict my chances of getting pregnant?
Not directly. AMH reflects egg quantity, not quality or overall fertility. Many factors influence your chances.
Should I have AMH tested if I’m not trying to conceive yet?
Yes. AMH can provide insight into your fertility timeline and help with planning, including options such as egg freezing.
Does AMH change over time?
Yes, AMH naturally declines with age, which is why timing can matter when planning treatment.
Can I improve my AMH level?
AMH itself cannot be significantly increased. Our focus is on optimising overall reproductive health and choosing the most effective treatment plan for you.
