Definition

AMH, or Anti-Müllerian Hormone, is a hormone produced by small developing follicles in the ovaries. A blood test measuring AMH is commonly used as one part of an ovarian reserve evaluation, which helps estimate the remaining pool of recruitable follicles in the ovaries (ASRM, 2020).

‍

A low AMH level generally suggests that the number of remaining recruitable follicles is lower than expected for a patient’s age. However, low AMH does not mean that pregnancy is impossible, and it does not directly measure egg quality.

AMH should therefore be interpreted together with age, menstrual history, ultrasound findings, other hormone testing, and the overall fertility picture rather than as a stand-alone “fertility score.”

‍

‍

Why Low AMH May Affect Fertility

Women are born with a finite number of eggs, and ovarian reserve naturally decreases over time. As the number of remaining follicles declines, AMH levels generally decline as well.

Low AMH may be especially relevant during fertility treatment because fewer recruitable follicles can sometimes result in a lower ovarian response to stimulation medications. This may mean that fewer follicles develop during an IVF cycle and potentially fewer eggs are available for retrieval. AMH is considered useful for predicting ovarian response and egg yield during controlled ovarian stimulation (ASRM, 2020).

‍

However, ovarian reserve and fertility are not the same thing.

A patient with low AMH may still:

• Ovulate regularly
• Produce a mature egg
• Conceive naturally
• Become pregnant through IUI
• Produce eggs during IVF
• Develop healthy embryos

AMH alone cannot reliably predict natural conception, embryo quality, or whether a particular embryo will result in pregnancy. Age remains particularly important because reproductive aging affects both egg quantity and egg quality.

‍

‍

Common Signs, Findings, or Concerns

Low AMH itself usually does not cause specific symptoms. Many patients discover it only after fertility testing.

Common situations associated with a low AMH result may include:

• Difficulty becoming pregnant
• Fertility evaluation after age 35
• Lower-than-expected antral follicle count
• Fewer follicles developing during ovarian stimulation
• Lower egg yield during a previous IVF cycle
• A family history of earlier menopause
• Previous ovarian surgery
• Previous chemotherapy or other treatments that may affect ovarian function
• Concerns about fertility preservation
• Planning pregnancy later in reproductive life

Some patients with low AMH continue to have regular menstrual cycles. A regular period does not necessarily indicate a high ovarian reserve, just as a low AMH result does not automatically mean that ovulation has stopped.

‍

Common Causes or Contributing Factors

Age-Related Decline

The most common reason for declining ovarian reserve is reproductive aging. The number of available follicles decreases over time, and AMH generally declines along with that process (ASRM, 2020).

Hormonal Contraception

Long-term hormonal contraception can temporarily suppress AMH and antral follicle count in some patients. ASRM notes that ovarian reserve markers may be lower during prolonged hormonal contraceptive use and can recover after discontinuation (ASRM, 2024).

Individual Variation

Women of the same age can have substantially different ovarian reserves. Genetics and individual reproductive biology can influence how rapidly ovarian reserve declines.

Ovarian Surgery

Previous surgery involving the ovaries, including certain surgeries for ovarian cysts or endometriosis, may sometimes reduce ovarian reserve depending on the procedure and the amount of ovarian tissue affected.

Endometriosis

Some patients with endometriosis may have reduced ovarian reserve, particularly when ovarian endometriomas or ovarian surgery are involved.

Chemotherapy or Radiation

Certain cancer treatments can damage ovarian follicles and reduce ovarian reserve. Current fertility-preservation guidance recognizes AMH as one marker that may help assess the remaining recruitable follicle pool after gonadotoxic treatment (ASRM, 2026).

Genetic or Medical Factors

In some patients, diminished ovarian reserve may occur earlier than expected because of genetic, autoimmune, or other medical factors.

Because many factors can influence interpretation, a single AMH result should be discussed in the context of the patient’s overall reproductive history.

‍

‍

How Low AMH Is Commonly Evaluated

AMH is usually only one part of an ovarian reserve evaluation.

A fertility specialist may consider:

• AMH blood testing
• Antral follicle count (AFC) by ultrasound
• FSH, usually measured early in the menstrual cycle
• Estradiol levels
• Age
• Menstrual-cycle history
• Previous response to fertility medications
• Previous egg-retrieval results
• Ovarian and pelvic ultrasound findings
• Medical and surgical history

AMH and antral follicle count are commonly used because they provide information about the pool of follicles that may potentially respond during ovarian stimulation.

‍

‍

AMH Is Not an Egg-Quality Test

One of the most important distinctions for patients to understand is that AMH primarily reflects egg quantity rather than egg quality.

A low AMH level does not automatically mean that the eggs remaining in the ovaries are poor quality.

Egg quality is strongly associated with age and chromosomal factors and cannot currently be measured directly with a routine AMH blood test. AMH or other ovarian reserve markers alone do not reliably predict embryo chromosomal quality (ASRM, 2023).

‍

‍

AMH Is Not a Pregnancy Test

AMH should also not be used by itself to predict whether someone can conceive naturally.

ASRM reports that ovarian reserve tests, including AMH, are poor predictors of short-term natural pregnancy potential in women without known infertility and have limited ability to predict unassisted conception in women with infertility (ASRM, 2020).

This is why a low AMH result should be interpreted as one piece of fertility information rather than a definitive prognosis.

‍

‍

Common Medical Treatment Options

There is no medication or procedure that reliably restores the ovarian follicle pool once ovarian reserve has declined.

Instead, fertility treatment is individualized according to factors such as:

• Patient age
• How long pregnancy has been attempted
• AMH and antral follicle count
• Ovulation
• Fallopian-tube status
• Semen-analysis results
• Previous pregnancies
• Previous fertility treatments
• Response to ovarian stimulation
• Personal reproductive goals

‍

Depending on the situation, treatment may include:

Timed Intercourse

For patients who are ovulating regularly and have no major additional fertility factors, a specialist may recommend continued attempts at natural conception with appropriately timed intercourse.

Ovulation Induction

Medications such as letrozole or clomiphene may be used in selected patients when ovulation or follicular development needs medical support.

IUI

Intrauterine insemination may be considered when other fertility factors are favorable.

IVF

IVF may be recommended when ovarian reserve is reduced, time is an important consideration, or additional infertility factors are present.

During IVF, AMH and antral follicle count can help the fertility specialist anticipate how the ovaries may respond to stimulation and individualize the medication protocol (ASRM, 2020).

A low AMH level does not automatically mean that IVF will fail. However, some patients may produce fewer follicles or eggs during stimulation, which can influence treatment planning (ASRM, 2020).

‍

Fertility Preservation

For patients who are not currently trying to conceive but have concerns about declining ovarian reserve, discussion with a reproductive endocrinologist about egg or embryo freezing may be appropriate.

‍

‍

What Patients Can Do During Their Fertility Journey

Receiving a low AMH result can be stressful, particularly when patients interpret the number as a direct prediction of their chance of becoming pregnant.

A more useful approach is to focus on the complete fertility picture.

Patients may consider:

• Reviewing the result with a fertility specialist
• Comparing AMH with antral follicle count
• Considering age alongside ovarian reserve
• Evaluating ovulation and menstrual-cycle patterns
• Having the fallopian tubes evaluated when appropriate
• Including semen analysis early in the fertility evaluation
• Reviewing previous ovarian surgery or medical treatment
• Discussing reproductive timing and goals
• Following fertility-treatment recommendations carefully
• Maintaining adequate sleep and balanced nutrition
• Avoiding smoking and recreational drugs
• Discussing supplements with the fertility team before taking them
• Avoiding claims that a supplement, diet, or therapy can “restore ovarian reserve”

Patients should also avoid blaming themselves for a low AMH result. Ovarian reserve is strongly influenced by age and individual biology and cannot be fully controlled through lifestyle.

How Acupuncture May Support Fertility Care With Low AMH

Acupuncture cannot increase the number of eggs remaining in the ovaries or reverse diminished ovarian reserve.

Its role is better understood as supporting the reproductive environment and the patient’s overall well-being while natural conception or fertility treatment is being pursued.

Depending on the individual patient, fertility acupuncture may be used to support:

Ovarian and Pelvic Circulation

Acupuncture may help support blood flow and circulation in the pelvic region through effects on local vascular and autonomic nervous-system regulation.

Healthy ovarian circulation contributes to the delivery of oxygen, hormones, and nutrients to ovarian tissues and developing follicles.

The Environment for Follicular Development

Follicular development is influenced by age, genetics, hormonal signaling, circulation, metabolic health, and ovarian reserve.

Acupuncture cannot create additional follicles or guarantee egg development, but it may be used as complementary care intended to support the physiological environment in which follicles develop.

Support During Ovarian Stimulation

Patients with low AMH may undergo ovarian stimulation for IUI, IVF, or egg freezing.

Acupuncture treatment during stimulation may be adjusted according to:

• Follicular response
• Medication schedule
• Ultrasound findings
• Pelvic fullness or discomfort
• Sleep
• Fatigue
• Headaches
• Digestive changes
• Emotional stress

The goal is to complement—not replace—the medication and monitoring provided by the fertility clinic.

‍

Egg Quality Support

Acupuncture should not be described as directly improving or guaranteeing egg quality.

A more appropriate goal is to support ovarian circulation, sleep, stress regulation, general health, and the physiological environment surrounding follicular development.

Because follicle development occurs over an extended period before ovulation or retrieval, many patients choose to begin fertility acupuncture before starting an IVF or IUI cycle.

‍

Stress and Emotional Support

Low AMH can create a sense of urgency and anxiety about reproductive timing.

Acupuncture may help support relaxation, sleep, nervous-system regulation, and emotional well-being during fertility testing and treatment.

Stress management does not increase ovarian reserve, and patients should not be made to feel that stress caused their low AMH.

When Low AMH Should Be Discussed With a Fertility Specialist

Low AMH does not always require immediate fertility treatment, but it may be useful to discuss the result with a reproductive endocrinologist when:

• Pregnancy has not occurred after an appropriate period of trying
• The patient is age 35 or older and planning pregnancy
• AMH is lower than expected for age
• Antral follicle count is also low
• Menstrual cycles have become irregular
• There is a history of ovarian surgery
• There is known endometriosis
• There has been chemotherapy or radiation treatment
• Previous IVF cycles produced a low number of eggs
• There is a family history of early menopause
• Fertility preservation (egg or embryo freezing) is being considered
• The patient is concerned about delaying pregnancy

AMH should rarely be interpreted in isolation. A fertility specialist can place the result in context with age, ultrasound findings, reproductive history, and other fertility factors.

Most importantly, low AMH does not mean there are no eggs remaining, and it does not mean pregnancy cannot occur. Its greatest clinical value is often in helping fertility specialists understand ovarian reserve and anticipate how the ovaries may respond to fertility treatment (ASRM, 2020).
