About the Anti-Mullerian Hormone Test
Purpose of the test
The AMH test tells you the number of remaining eggs you have and whether your ovaries might be aging too quickly. It may reveal that you have a shorter window to get pregnant. (Anti-Mullerian Hormone (AMH) Test: Purpose, Levels & Results) Ovarian reserve declines naturally with age, but not at the same rate for everyone. This test helps find women whose reserve is dropping faster than expected, which matters for fertility planning, egg freezing, and assisted reproductive treatments like in vitro fertilization (IVF).
The test serves two clinical purposes:
- Diagnosis: Ordered when symptoms like irregular periods, acne, excess body hair, or unexplained infertility suggest PMOS or premature ovarian insufficiency (POI).
- Monitoring: Your provider may do an AMH test to determine if an ovarian mass is a granulosa cell tumor. AMH levels may also be used to check if treatment is working or the tumor has returned.
AMH helps assess menopausal status too. According to the National Library of Medicine, if you’re younger than age 40 and have symptoms of menopause, an AMH level that’s lower than average for your age may be a sign of primary ovarian insufficiency. A gradual decline through the late 30s and early 40s is a normal part of perimenopause.
While AMH is connected to your egg count, it doesn’t predict your fertility (with or without treatments), or when you’ll go through menopause. A low AMH doesn’t mean pregnancy is impossible. Egg quality, uterine health, ovulation regularity, and partner fertility matter just as much. The AMH test doesn’t include other reproductive hormones like follicle-stimulating hormone (FSH) or luteinizing hormone (LH) unless those are ordered separately.
What does the anti-mullerian hormone test measure?
This test covers one marker from a single blood sample processed at a CLIA-certified lab.
- Anti-Mullerian Hormone (AMH): A hormone made by follicle cells in the ovaries (and by Sertoli cells in the testes) that reflects the size of your remaining egg supply.
You can have an AMH test at any point during your menstrual cycle. FSH and estradiol rise and fall with follicle development, so their results depend heavily on when you test. AMH doesn’t work that way. Small antral follicles produce it continuously, regardless of which follicle is dominant that month. That stability makes AMH the preferred single marker for checking ovarian reserve.
In males, Sertoli cells in the testes produce AMH, and it plays a role in early sexual development. According to the National Library of Medicine, in adult males, AMH provides insight into testicular function as a Sertoli-cell marker and comes up in fertility or hormonal workups. This is a less common clinical use than in females. AMH values in adult males are generally lower than in reproductive-age females, and interpretation varies by lab and assay.
When should I get an anti-mullerian hormone test?
Consider testing if any of these apply:
- Concerns about fertility or egg supply before trying to conceive
- Planning egg freezing or IVF
- Irregular or absent menstrual periods
- Symptoms of PMOS: irregular cycles, acne, excess facial or body hair, or unexplained weight gain
- A history of chemotherapy or ovarian surgery that may have affected egg supply
- Suspected premature ovarian insufficiency or early menopause
- Checking for undescended or absent testes in a male patient
There’s no universal AMH screening recommendation. Testing is prompted by a specific clinical question, such as:
- Women planning fertility treatment or egg preservation who want a baseline reserve check
- Women in their late 30s or early 40s concerned about their remaining fertility window
- Women with suspected PMOS who need supporting evidence
- Women after cancer therapy to see how treatment affected ovarian function
How It Works
How to get tested
Ask your provider about an AMH blood test. Most providers order it through a CLIA-certified lab. A blood draw at a lab, clinic, or your provider’s office is the standard collection method. Results are typically ready within one to five business days after the lab receives your sample, though timing can vary by lab.
Talk with your provider about what your results mean and whether follow-up testing is needed.
Before the test
No fasting is required. Eat and drink normally.
Tell your provider about any hormonal medications you’re taking, including birth control pills, patches, rings, or hormone therapy. Some evidence suggests these can suppress AMH levels, making your egg supply look lower than it actually is. Your provider can decide whether to adjust timing or note this when reading your results.
You can have an AMH test at any point during your menstrual cycle, as noted by Cleveland Clinic. AMH levels don’t shift much from day to day, so any day works.
Bring a list of your current medications and supplements. If you have questions about anything else to avoid, check with your provider.
During the test
- Check in at the lab or clinic and confirm your identification.
- A phlebotomist draws blood from a vein in your arm. You’ll feel a brief pinch.
- The draw takes about two minutes. A small bandage covers the site afterward.
The whole visit usually runs 15 to 30 minutes. Some people notice light bruising at the draw site over the next day or two. That’s normal.
Call your provider if you notice lasting pain, swelling, or signs of infection at the site.
After the test
Results are typically ready within one to five business days after the lab receives your sample, though timing can vary by lab. You’ll usually get them through your provider’s patient portal or office.
Don’t interpret your results alone. AMH values are most useful when read alongside your age, symptoms, and clinical history.
What Do My AMH Results Mean?
AMH results are reported in nanograms per milliliter (ng/mL). Higher values generally reflect a larger egg supply. Lower values suggest a smaller one. The ranges below are approximate and vary by lab and assay.
| AMH Level | Approximate Value (ng/mL) | What It May Suggest |
|---|---|---|
| High | Above 3.5 | Large follicle pool; may be seen with PMOS |
| Normal (age 25 to 35) | 1.0 to 3.5 | Ovarian reserve within expected range |
| Normal (age 35 to 40) | 0.5 to 2.5 | Age-related decline, still within range |
| Low | Below 0.5 to 1.0 | Diminished ovarian reserve for age |
| Very low / undetectable | Below 0.2 (varies by assay) | May be consistent with menopause or POI |
Your provider reads your result in the context of your age, symptoms, and reproductive history.
If your AMH levels are normal
Your ovarian reserve is within the expected range for your age. That’s reassuring if you’re planning for pregnancy. But a normal AMH doesn’t guarantee conception. Egg quality, ovulation regularity, uterine health, and partner fertility all play a role. Your provider may suggest additional testing like FSH, estradiol, or a transvaginal ultrasound to count visible follicles.
If your AMH levels are low
Your egg supply is smaller than expected for your age. That doesn’t mean you can’t get pregnant. But your window for conception may be shorter, and your provider may recommend moving forward with fertility planning sooner rather than later.
Low AMH can reflect the effects of chemotherapy, genetics, smoking, or prior ovarian surgery. An AMH test may also reveal how well you respond to injectable fertility drugs to stimulate your ovaries to mature multiple eggs in preparation for in vitro fertilization (IVF), according to Cleveland Clinic. A low AMH may predict a weaker response to ovarian stimulation, meaning fewer eggs retrieved. Your provider can walk you through what this means for your situation and whether egg freezing or other options make sense now.
If your AMH levels are high
Your ovaries have a larger-than-expected pool of developing follicles. That sounds positive, but very high AMH is often linked to PMOS. Anti-Mullerian hormone synthesized by the pre-antral and small antral ovarian follicles appears to play an important role in the pathophysiology of PMOS, and serum AMH levels are often elevated in women with PMOS. (The Role of Serum Anti-Mullerian Hormone Measurement in the Diagnosis of Polycystic Ovary Syndrome) High AMH alone doesn’t diagnose PMOS. Your provider will look at symptoms, other hormone levels, and possibly an ultrasound before making that call.
If you’re planning IVF, high AMH may predict a strong response to ovarian stimulation. That’s generally good, but it raises the risk of ovarian hyperstimulation syndrome (OHSS), where the ovaries overrespond to fertility medications. Your provider will factor your AMH level into how they dose your stimulation protocol.
For males, AMH interpretation differs. In adult males, AMH values are generally lower than in reproductive-age females. What a higher or lower value reflects depends on the clinical question being evaluated, and interpretation varies by lab and assay.
