If you recently had your Anti-Müllerian Hormone, or AMH, tested as part of a fertility workup, you may be wondering what the number really means.

You may also be asking:

Can I improve my AMH?

Did my lifestyle cause my AMH to be low?

Can stress, sleep, diet, or supplements change it?

AMH is commonly used as a marker of ovarian reserve. In simple terms, it helps fertility specialists estimate how many small developing follicles may be available in the ovaries.

But AMH is not a perfect fertility score.

It does not directly measure egg quality.

It does not predict whether you can get pregnant naturally.

And it should not be interpreted by itself.

Age, genetics, ovarian biology, medical history, lab variation, and certain lifestyle factors may all influence the bigger picture.

While AMH is largely shaped by age and genetics, research suggests that some lifestyle factors may also affect ovarian function, hormone balance, inflammation, and overall reproductive health.

This article walks through seven lifestyle factors that may impact AMH levels or the ovarian environment connected to fertility.

This article is for informational purposes only and is not intended to provide medical advice. Always consult your fertility specialist, OB-GYN, reproductive endocrinologist, or qualified healthcare provider for personalized interpretation of AMH results, testing, supplements, and treatment planning.

AMH stands for Anti-Müllerian Hormone.

It is produced by granulosa cells in small ovarian follicles.

Fertility specialists often use AMH to help estimate ovarian reserve and predict how the ovaries may respond to fertility medications during treatments like IVF.

AMH is commonly used during fertility evaluations because it is relatively stable across the menstrual cycle compared with some other hormones.

AMH does not directly tell you:

AMH is helpful, but it is only one part of the fertility picture.

Stress is not the sole cause of fertility problems.

And low AMH is not your fault.

But chronic stress may affect the body in ways that influence hormone balance, ovulation, sleep, inflammation, and overall reproductive function.

When the body is under ongoing stress, cortisol may remain elevated or become dysregulated.

Over time, this may affect:

Some studies suggest chronic stress may disrupt ovarian function indirectly.

This does not mean a stressful month caused your AMH to drop.

But long-term stress may be one factor worth addressing as part of a broader fertility wellness plan.

High stress may be linked with conditions such as hypothalamic amenorrhea, irregular ovulation, poor sleep, and inflammation.

These issues can overlap with lower ovarian function or poor response in some people.

Smoking is one of the clearest lifestyle factors linked to lower ovarian reserve and reproductive aging.

Cigarette smoke contains toxins that may damage ovarian cells and accelerate follicle loss.

Smoking has been associated with:

Secondhand smoke exposure may also affect reproductive hormones.

Follicles are not easily replaced.

Anything that accelerates ovarian aging may matter, especially if you are already trying to conceive, have low AMH, or are preparing for IVF.

If you smoke, quitting may be one of the most important fertility-supportive steps you can take.

If you are exposed to secondhand smoke, reducing that exposure may also be helpful.

Avoiding active and passive smoke exposure may support long-term ovarian health and overall fertility.

There is no diet that can “cure” low AMH.

But nutrition can influence inflammation, insulin sensitivity, hormone balance, nutrient status, and overall reproductive health.

Diet may affect ovarian health indirectly through:

A diet high in refined sugar, trans fats, ultra-processed foods, and low nutrient density may contribute to inflammation and metabolic dysfunction.

On the other hand, a nutrient-dense eating pattern may support reproductive health.

Ask your provider whether you should evaluate or focus on:

Consider including:

Focus on a whole-foods, Mediterranean-style pattern that supports inflammation balance, hormones, and overall fertility health.

Sleep affects more than energy.

It helps regulate hormones, metabolism, immune function, inflammation, insulin sensitivity, and reproductive rhythms.

Poor sleep may create a less supportive environment for ovarian health.

Sleep disruption may affect:

Melatonin is especially interesting because it plays a role in circadian rhythm and may also support antioxidant activity in the ovarian environment.

Some preliminary research has looked at irregular sleep patterns, night shift work, and ovarian reserve markers, but more research is needed.

You may notice:

Try:

Aim for 7 to 9 hours of quality sleep and a consistent sleep-wake rhythm when possible.

Body weight can influence reproductive hormones, ovulation, insulin sensitivity, inflammation, and AMH interpretation.

Both low and high BMI may affect the hormonal environment in different ways.

Being underweight, under-fueled, or over-exercising may contribute to hypothalamic suppression.

This can affect:

In some cases, this may be associated with lower AMH or reduced ovarian activity.

Higher BMI may be associated with insulin resistance, inflammation, and hormone changes.

In PCOS, AMH may be elevated because there are often more small follicles.

But higher AMH in PCOS does not automatically mean better fertility.

It may reflect follicle number, not necessarily egg quality or regular ovulation.

AMH needs context.

A person with PCOS may have high AMH and still struggle to ovulate.

A person with low BMI may have cycle disruption due to low energy availability.

The goal is not weight perfection.

The goal is supporting a stable, nourished, metabolically healthy body.

Hormonal birth control can affect AMH test results.

This is important because some people test AMH shortly after stopping the pill, patch, ring, injection, implant, or hormonal IUD and feel alarmed by the number.

Some studies suggest oral contraceptives and other hormonal contraception may temporarily suppress AMH levels.

This does not mean birth control depleted your eggs.

It means ovarian activity and hormone signals may be temporarily quieter while ovulation is suppressed.

For many people, AMH may rebound after stopping hormonal contraception, often within a few months.

If your AMH was tested while you were on hormonal birth control or shortly after stopping, your provider may interpret the result with caution.

They may recommend repeating AMH later or comparing it with antral follicle count.

Hormonal birth control may temporarily lower measured AMH, but that does not mean it permanently reduces egg supply.

Vitamin D acts more like a hormone than a simple vitamin.

Vitamin D receptors are found in reproductive tissues, including ovarian tissue.

Some research has explored a possible relationship between vitamin D levels and AMH, although findings are mixed.

Vitamin D may play a role in:

Low vitamin D is common, especially in people who have limited sun exposure, darker skin, northern climates, indoor jobs, or certain absorption issues.

Vitamin D deficiency may be worth identifying and correcting because it can affect overall health and may play a role in reproductive function.

That does not mean vitamin D supplementation will automatically raise AMH or improve fertility outcomes for everyone.

But testing can help you and your provider make a more informed plan.

If you are trying to conceive or have low AMH, vitamin D testing may be worth discussing with your provider.

A low AMH result can feel scary.

But before panicking, it helps to ask better questions.

Bring these questions to your next appointment:

Your AMH level is influenced mostly by biology, age, and genetics.

But lifestyle still matters.

Not because lifestyle can magically reverse ovarian aging.

And not because low AMH is your fault.

Lifestyle matters because stress, sleep, smoking, nutrition, body weight, birth control timing, and vitamin D can all influence the broader reproductive environment.

AMH is one piece of the puzzle.

It should be interpreted alongside your age, antral follicle count, FSH, estradiol, cycle history, symptoms, medical history, and fertility goals.

The good news is that many supportive habits are within your control.

Eating nutrient-rich foods.

Sleeping more consistently.

Avoiding smoke exposure.

Managing stress.

Checking vitamin D.

Fueling your body.

Asking better questions.

These steps may not guarantee a higher AMH number, but they can help create a healthier foundation for fertility treatment, conception, and overall wellbeing.

Your AMH is information.

It is not your worth.

It is not your final outcome.

And it is not the whole story.
