Hormones, hormones, hormones. You are probably more familiar with suchestrogen,Insulin,progesterone,oxytocin, ETestosterone. And if you were pregnant, you might also be aware of human chorionic gonadotropin (hCG).
As such, anti-Müllerian hormone (AMH) may not be the most talked about hormone - or even the best known in the context of reproductive health. But it's definitely worth understanding, especially if you're hoping to get pregnant in the future.
Here, we dive deep into AMH, including:
- What AMH Levels Can Tell You
- what levels of AMHchickenstell you
- The relationship of AMH with FSH and in vitro fertilization
- how your doctor can use the test results
Anti-Müllerian hormone, or AMH, is a hormone produced by the granulosa cells in the ovarian follicles. According toAmerican College of Obstetricians and Gynecologists (ACOG), AMH production reflects your ovarian reserve.
Think of your ovarian reserve as a basket full of eggs. You are usually born with a basket full of eggs, and those eggs will be consumed throughout your life.
An AMH test can tell you your egg count. A low AMH value indicates aDecreased ovarian reserve (PAIN)or low egg count, which is why the hormone is linked to fertility. In other words, when you have PAIN, your egg basket starts to empty.
But here's the kicker: bass AMHsuggestsPAIN, but it is ambiguous. And the AMH toonosay if the eggs in the basket are good eggs.
Some doctors order an AMH level as a "fertility test". But this is problematic precisely because AMH doesn't tell the whole story.
That's why ACOG says this assessmentshould notorganized for people who are not infertile to discuss their reproductive status and future fertility potential.
In fact, testing the AMH if you're under 35 and not diagnosed as infertile may raise unnecessary alarms, he says.Mark P. Trolice,MD, Director of Fertility CARE: The IVF Center and Professor of Obstetrics and Gynecology at the University of Central Florida College of Medicine.
“While it is possible, AMH screening results may lead people to voluntarily make choicesfreeze your eggs, comprehensive counseling on the true meaning of AMH levels is essential,” he explains.
If you are looking for specific answers about natural fertility, AMH Levels is not the place for you. "That's because AMH doesn't accurately predict natural fertility," says Trolice.
However, if you go throughIn vitro fertilization (IVF), Trolice says that AMH can be used to predict the number of eggs you can produce, as well as the dosage of drugs to stimulate egg production.
Jessica Scottie, MD, REI, OB-GYN deTennessee reproductionyouactive medicine, agrees. "In a non-infertile population, AMH levels do not predict the time it takes to conceive and do not predict infertility," she says.
(We know "not infertile" might sound like a tricky double negative, but it refers to people who aren't trying to conceive and therefore have no documented difficulties.)
However, when used as part of an infertility study, Scotchie says, AMH can help doctors understand whether the ovaries are aging faster than they should be and whether fewer eggs are left.
"AMH levels may also better predict how ovarian stimulation will progress when used in the design of IVF protocols," she says.
Currently, the best measure of ovarian aging, according to Trolice, is the combination of your chronological age, antral follicle count (AFC) on an ultrasound (ultrasound), and AMH. AFC counts the number of small cysts on the ovary that represent eggs.
According to Trolice, as the AMH reflects the number of oocytes remaining in the ovary, the AFC and the AMH are excellent guides for estimating the number (Crowd) of eggs you have.
However, he points out that his birthday is the best measure of that.Qualityof eggs. "While quantity and quality decline with age, age is the best predictor of your chances of conceiving," he says.
Furthermore, Trolice says that using a screening test for decreased ovarian reserve in a population at low risk of DOR will result in a higher number of false positives.
This means labeling people as having PAIN when in fact many have normal ovarian reserve. Therefore, he does not recommend using AMH to predict fertility.
In other words, if 100 people in their 20s take the AMH test and 15 of them get the DOR label as a result, that could cause undue stress for those 15 - although perhaps few of them will.strictly speakingcontinue to have problems getting pregnant.
Testing your AMH level is a simple blood test. As the measurement remains virtually stable throughout the entire cycle, your doctor may order a test at any time.
As a general guide, the following values (in nanograms per milliliter) apply.lower limit of serum AMH levels by age:
- 45 years: 0.5 ng/ml
- 40 years: 1 ng/ml
- 35 years: 1.5 ng/ml
- 30 years: 2.5 ng/ml
- 25 years: 3.0 ng/ml
The above values are considered conservative estimates, and the limits are also dependent on the laboratory. All results should be discussed with the physician who ordered the test.
According to Trolice, AMH levels below 1.6 ng/ml predict fewer eggs retrieved with IVF. Values below 0.4 ng/ml are too low.
While test results are helpful, it's also important to note that as you age, you have fewer eggs. This is normal! This means that AMH levels decline during your reproductive life.
Follicle Stimulating Hormone (FSH) is produced by the pituitary gland and is involved in sexual development and function. FSH stimulates the growth of eggs in the ovary, which increases estrogen and subsequently progesterone.
AhigherFSH generally indicates low ovarian reserve while alowerAMH indicates low reserve.
As with AMH, your doctor may order a test to find out your FSH levels to determine your current ovarian reserve.
WhileFSHcan be a more useful toolExperts |agree that AMH may be a more reliable indicator of ovarian reserve because levels remain constant throughout the menstrual cycle – and from cycle to cycle.
In general, Trolice says that the more eggs produced during IVF stimulation and recovery, the more likely it is that an adequate number of good embryos will develop and be transferred. (When eggs are fertilized by sperm, you get embryos. Not all eggs retrieved will necessarily be successfully fertilized in IVF.)
“As a woman ages, the percentage of chromosomal abnormal eggs that contribute to abnormal embryos increases. Therefore, the lower the number of eggs retrieved, the lower the percentage of embryos,” she says. While lower levels of AMHAgainLess successful IVF, Trolice says this is most noticeable in women in their 30s and older.
Using our egg basket analogy again to explain quantity and quality, in your 20s and 30s you typically have more eggs - and more "golden" (good) eggs. In your late 30s or older, you typically have fewer Balls and fewer Balls d'Or.
But a young woman with few eggs (low AMH level) should still have a higher percentage of golden eggs and therefore better IVF success (more quality eggs retrieved) than an older person.
An older person can certainly get lucky and have a lot of eggs left over, but a higher percentage of these eggs will have lost their "golden status" with aging and may not give rise to normal embryos.
Scotchie points out that lower levels of AMH (<1) are associated with:
- lower egg production at collection
- higher risk of cycle termination (meaning your IVF cycle will be terminated and your eggs will not be retrieved)
- higher rates of abnormal fertilization

Unfortunately, there are no proven ways to increase your AMH levels.
But while you cannot increase your egg count (amount) of eggs, you can work to maintain egg quality by not smoking and maintaining a healthy weight as directed by your doctor. Both
Remember, even if you have fewer eggs, you can still have good eggs - and this will increase your chances of fertility success.
In addition to determining your egg count, AMH levels can help your doctor with other conditions, such as:Polysystemic Ovary Syndrome (PCOS)and menopause.
PCOS is one of the most common female hormonal disorders. But while many people with PCOS have elevated levels of AMH, there is no consensus from medical societies (such asACOG), to use AMH levels as a diagnostic criterion for PCOS.
When it comes to predicting the onsetMenopause, the ACOG says that research on AMH levels in role-playing has yielded conflicting results.
There is some evidence that the AMH can be used as a general reference, but not as a definitive schedule. a younger
Some people believe that AMH levels can help predict a baby's gender, but Trolice says he is not aware of any evidence that AMH has any effect on determining a baby's gender. "Male and female fetuses produce different amounts of AMH during pregnancy," he says.

AMH levels help determine your ovarian reserve, or number of eggs, at the time of the test. These values decrease with age. Doctors may order an AMH test as a diagnostic tool to start a conversation about fertility. But AMH levels alone cannot predict infertility.
If you have concerns about your AMH levels or concerns about fertility, it is important that you speak with your doctor or healthcare professional.reproductive endocrinologist and infertility specialist.
FAQs
What does AMH hormone tell you? ›
AMH levels help show how many potential egg cells a woman has left. This is known as the ovarian reserve. If a woman's ovarian reserve is high, she may have a better chance of getting pregnant. She may also be able to wait months or years before trying to get pregnant.
What is anti Mullerian hormone AMH test results? ›AMH is an important fertility test to tell us about a woman's ovarian reserve as it stands today. Higher AMH values (greater than 1 ng/mL) usually signify that a woman has a normal ovarian reserve. Lower numbers (less than 1 ng/mL) may indicate a woman with diminished ovarian reserve (DOR).
What is a good level for AMH? ›According to Trolice, AMH levels below 1.6 ng/mL predict a smaller number of eggs retrieved with IVF. Levels below 0.4 ng/mL are severely low. While test results are helpful, it's also important to note that as you age, you have fewer eggs. This is normal!
What is a good AMH level for age? ›What does having low AMH levels mean? Having low AMH levels can indicate that your ovaries are producing less of the preantral follicles. This is important as the fewer the number of follicles there are means there less than can be stimulated for assisted contraception.
What AMH level indicates PCOS? ›Background. Polycystic ovarian syndrome (PCOS) affects up to one-fifth of women of reproductive age and causes anovulatory subfertility. Some studies have recommended that an anti-Müllerian hormone (AMH) level greater than 3.8–5 ng/mL can be used for diagnosing PCOS.
What is a good AMH level to get pregnant at 35? ›45 years old – 0.5ng/ml. 40 years old – 1ng/ml. 35 years old – 1.5ng/ml. 30 years old – 2.5ng/ml.
What AMH level indicates infertility? ›| Interpretation (women under age 35) | AMH Blood Level |
|---|---|
| High (often PCOS) | Over 4.0 ng/ml |
| Normal | 1.5 – 4.0 ng/ml |
| Low Normal Range | 1.0 – 1.5 ng/ml |
| Low | 0.5 – 1.0 ng/ml |
Does having a low AMH mean you have poor egg quality? Important point here: low AMH does not mean that you have bad quality eggs. Age is the important factor when it comes to egg quality. The younger you are when you freeze your eggs, the higher chance that they will lead to healthy embryos and a baby.
What is a good AMH level for age 38? ›The median AMH values were 4.23 ng/mL in 20–25 years' age group, 3.48 ng/mL in women aged 26–30 years, 2.43 ng/mL in women aged 31–35 years, 1.28 ng/mL in women aged 36–40 years and0. 52 ng/mL in 40–44 years' age group.
Can stress affect AMH? ›
When a stimulus is perceived as stressful, the HPA axis and SAM pathway may be activated [1]. As a result, growing follicles are lost due to the oxidative damage of ovarian follicle cells, which leads to a decrease of AMH level.
Does low AMH mean menopause? ›Several authors reported that AMH determination was a valuable predictor of menopause [8]. It is considered that the level of AMH is very low, or even below detectable limits approximately 5 years before menopause [5].
Does low AMH mean ovarian failure? ›Anti-Müllerian hormone (AMH) is now recognized as the most reliable marker of ovarian reserve status [1,5,6]. Decreased serum AMH levels are a reflection of decreased ovarian reserve, and very low or undetectable AMH levels in women with amenorrhea strongly suggest ovarian failure [1,3,7].
Can I get pregnant with low AMH? ›You can get pregnant naturally if you're having low levels of AMH as it fluctuates every month. However, it is possible for you to get pregnant naturally with your eggs or with donor eggs if you have a low AMH level. Your low AMH level will not decide your fertility and there are other ways to improve your fertility.
Does AMH indicate egg quality? ›AMH is one of those hormones. The level of AMH in a woman's blood helps doctors estimate the number of follicles in her ovaries; the more follicles a woman has, the more eggs she can release, and the better her chances of pregnancy.
What is the AMH value for ovarian cyst? ›Ovarian cyst diameters measured from 4.6-13 cm with mean size of 7.6 cm (95% CI: 7-8.2). Statistical analysis of AMH levels in studied population before the operation showed a mean value of 3.77 ng/mL (95% CI: 1.58-5.96 ng/mL) which declined to 1.87 ng/mL (95% CI: 0.67-3.07 ng/mL) 1 month after the operation.
What is a good AMH level to get pregnant at 40? ›30 years old: 2.5 ng/mL. 35 years old: 1.5 ng/ mL. 40 years old: 1 ng/mL. 45 years old: 0.5 ng/mL.
Can I get pregnant at 37 with low AMH? ›Can you still get pregnant with low AMH? While low AMH does impact your overall reproductive window, you can absolutely still get pregnant and have a successful pregnancy if your egg supply is in the lower range for your age group. After all, you only need one healthy egg and one healthy sperm to conceive.
Can I get pregnant at 42 with low AMH? ›Age is an independent variable that must be considered with respect to a woman's chances of getting pregnant. A low AMH level after age 40 years is associated with a poor outcome. In younger patients, low AMH patients will have reasonable pregnancy rates although they will produce few eggs.
Does vitamin D increase AMH? ›Vitamin D was shown to have a direct effect on AMH production, and women with higher vitamin D concentrations maintained their ovarian reserve for longer. In another study, lower serum 25(OH)D levels have been accompanied by higher serum FSH levels.
How many eggs are left with low AMH? ›
Usually, when the Anti-Müllerian hormone level is less than 1, we should obtain a low number of eggs — around 3.
Do you ovulate every month with low AMH? ›I HAVE LOW AMH. DOES IT MEAN I AM INFERTILE? No. As long as you have regular periods and you will ovulate one egg per month.
Is AMH a good indicator of fertility? ›AMH is very often considered to be a 'fertility test', when in reality, it is a 'screening test'. It is a useful indicator of the number of eggs remaining, rather than the quality of those eggs. A low AMH result does not mean that the person is infertile.
Is AMH a good predictor of fertility? ›In women, the anti-Müllerian hormone (AMH) is secreted by the granulosa cells of growing follicles. Its measurement is strongly correlated with antral follicle count and represents a reliable marker of ovarian reserve.
How can I improve my AMH and egg quality? ›It is possible to increase your AMH levels naturally. You can encourage your body to naturally raise levels of AMH by eating a diet which is rich in necessary nutrients, such as vitamin D. There is also research that shows women taking the micronutrients present in Impryl actually experienced increased AMH levels.
Does low AMH mean early menopause? ›In minimally adjusted models, each 0.10 ng/ml lower AMH was associated with a 14% higher risk of early menopause (OR = 1.14; 95% CI = 1.10–1.17; P < 0.001).
How many eggs do you lose per period? ›A woman is born with all her eggs. Once she starts her periods, 1 egg develops and is released during each menstrual cycle. Pregnancy happens if a man's sperm meet and fertilise the egg. Sperm can survive in the fallopian tubes for up to 7 days after sex.
How do I know if I am fertile enough to get pregnant? ›If your menstrual cycle lasts 28 days and your period arrives like clockwork, it's likely that you'll ovulate on day 14. That's halfway through your cycle. Your fertile window begins on day 10. You're more likely to get pregnant if you have sex at least every other day between days 10 and 14 of a 28-day cycle.
What is the lowest AMH level for IVF? ›AMH was considered to be low with levels 1 ng/ml and below. Levels below 0.5 ng/ml were considered extremely low level. Eighty-four women decided not to be enrolled in the IVF/ICSI program after explaining the poor prognosis in their individual cases.
Does it take longer to conceive with low AMH? ›The basic finding: women who had low AMH levels didn't differ in their ability to conceive from women with normal AMH levels and, similarly, women with high FSH levels didn't differ significantly from women with normal FSH levels.
