If you have recently undergone fertility testing, you may have come across the term AMH levels. For many people, receiving a low AMH result can be confusing and worrying, particularly if they are planning to start a family now or in the future.
While low AMH levels can provide important information about fertility, they do not tell the whole story. Many women with low AMH levels go on to conceive naturally or successfully through fertility treatment. Understanding what AMH is and what low levels may mean can help you make informed decisions about your reproductive health.
In this guide, we explain what AMH is, how low AMH levels can affect fertility, what causes low AMH levels, and how Fertility Choice can help you navigate your fertility journey.
What is AMH?
AMH stands for anti-müllerian hormone, a hormone produced by the small follicles within the ovaries. These follicles contain immature eggs that may develop and mature in future menstrual cycles.
Because AMH is produced by developing follicles, AMH levels are commonly used as an indicator of ovarian reserve, which refers to the estimated number of eggs remaining in the ovaries.
An AMH blood test can provide valuable insight into fertility potential and is often used during fertility assessments, IVF planning, and fertility preservation consultations.
Why are AMH levels important?
One of the reasons fertility specialists measure AMH levels is because they can help estimate how the ovaries may respond to fertility treatment.
AMH levels can assist with:
- Assessing ovarian reserve
- Planning IVF treatment protocols
- Evaluating fertility preservation options
- Identifying potential fertility concerns earlier
- Supporting family planning decisions
It is important to remember that AMH primarily reflects egg quantity rather than egg quality.
What are low AMH levels?
Low AMH levels generally indicate a reduced ovarian reserve, meaning there are fewer remaining follicles in the ovaries than expected for a person’s age.
This does not necessarily mean pregnancy is impossible. Rather, it suggests that the available pool of eggs may be smaller.
A low AMH result should always be interpreted alongside other fertility assessments, including age, hormone testing, ultrasound findings, and overall reproductive health.
How can low AMH levels affect fertility?
Reduced ovarian reserve
The most direct effect of low AMH levels is a reduced ovarian reserve.
As the number of available eggs decreases, the chances of releasing a healthy egg during ovulation may gradually decline. This can make conception more difficult over time.
Less time for family planning
Women with low AMH levels may have a shorter reproductive window compared to those with higher ovarian reserves.
For this reason, fertility specialists often encourage earlier fertility planning when low AMH levels are identified.
Reduced response to fertility medication
During IVF treatment, fertility medication is used to stimulate the ovaries to produce multiple mature eggs.
Women with low AMH levels may produce fewer eggs during stimulation, which can influence treatment planning and expected outcomes.
Potential impact on fertility preservation
Low AMH levels can affect decisions around egg freezing and fertility preservation. Since fewer eggs may be retrieved during a single cycle, earlier intervention may be recommended when preserving future fertility is a goal.
What causes low AMH levels?
There are several factors that can contribute to low AMH levels.
Age
Age is the most common cause of declining AMH levels.
Women are born with all the eggs they will ever have, and this supply naturally decreases over time. AMH levels generally decline as women get older, particularly from the mid-thirties onwards.
Genetics
Some women naturally have lower ovarian reserves due to genetic factors. Family history can sometimes play a role, particularly if close relatives experienced early menopause.
Previous ovarian surgery
Surgical procedures involving the ovaries may affect ovarian reserve and lead to lower AMH levels.
Certain medical treatments
Chemotherapy, radiation therapy, and some medical treatments can damage ovarian tissue and reduce the number of available follicles.
Endometriosis
Endometriosis can sometimes affect ovarian function and may contribute to reduced ovarian reserve in some women.
Premature ovarian insufficiency
In some cases, low AMH levels may be associated with premature ovarian insufficiency, where ovarian function declines earlier than expected.
Does low AMH mean you cannot get pregnant?
No.
One of the biggest misconceptions about AMH levels is that a low result means pregnancy is impossible. This is not true.
AMH measures the number of remaining eggs but does not directly measure egg quality or the ability to conceive naturally.
Many women with low AMH levels achieve successful pregnancies, either naturally or with fertility treatment.
A fertility specialist will consider many factors when assessing fertility potential, including:
- Age
- Ovulation patterns
- Egg quality
- Sperm health
- Uterine health
- Fallopian tube function
- Overall reproductive health
This is why a low AMH result should never be viewed in isolation.
What can you do if you have low AMH levels?
If you have received a low AMH result, the most important step is to seek professional guidance.
Your fertility specialist may recommend:
- Additional fertility testing
- Ultrasound assessment of ovarian reserve
- Earlier family planning discussions
- Egg freezing if future fertility preservation is desired
- IVF treatment where appropriate
- Ongoing fertility monitoring
Early assessment often provides more options and allows for proactive decision-making.
How Fertility Choice can help
At Fertility Choice, we understand that receiving unexpected fertility test results can feel overwhelming.
Our experienced fertility specialists provide comprehensive fertility assessments to help you understand what your AMH levels mean in the context of your overall reproductive health.
Our services include:
- AMH testing and fertility evaluations
- Ovarian reserve assessments
- Fertility preservation consultations
- Egg freezing services
- Personalised IVF treatment planning
- Ongoing fertility support and guidance
Every fertility journey is unique, and our goal is to provide clear information, compassionate care, and personalised treatment options that align with your goals.
Why early fertility testing matters
Understanding your AMH levels before you begin trying for a family can be incredibly valuable.
Early fertility testing allows you to:
- Make informed reproductive decisions
- Explore fertility preservation options
- Identify potential concerns sooner
- Create realistic family planning timelines
- Access treatment earlier if needed
Knowledge empowers you to take control of your reproductive future rather than relying on guesswork.
Conclusion
Low AMH levels can provide important insight into ovarian reserve, but they do not define your fertility or determine your chances of becoming a parent. While low AMH levels may influence fertility planning and treatment decisions, many women with reduced ovarian reserve successfully conceive and build their families.
