Amh And Assisted Reproduction

What is Anti-Mullerian Hormone (AMH) Test?

Another of the advantages of this hormonal determination is that it is very useful for assisted reproduction professionals, as they can decide which treatment is most suitable for each patient, as well as the pattern of hormonal medication required.

It has been shown that there is a correlation between the values of HMA and the degree of ovarian response to ovarian stimulation. Thus, patients with high AMH may be at risk of hyperstimulation, while patients with low AMH are more likely to have a low response.

The latter, therefore, will need higher doses of gonadotropins to achieve multiple follicular development.

AMH can be useful to better predict the success of assisted reproduction treatments and to be able to make a more accurate indication of the appropriate technique for each patient.

In addition to all this, the anti-Mullerian hormone also allows a better study of fertility physiology, since its levels have also been related to the quality of the eggs. It is said that only healthy follicles, which will give rise to a high-quality oocyte, are capable of producing AMH.

Is There Anything Else I Should Know

Some in the medical community are advocating the use of AMH as a more routine test, for predicting the end of fertility and the onset of menopause, but there is not a consensus on this use. It is not considered a diagnostic or stand-alone test, but one that supports the diagnosis of one of the conditions mentioned.

Other female hormones fluctuate with a womans monthly cycle however, AMH is produced by growing follicles at a relatively steady rate throughout the month. It is also not affected by oral contraceptives or pregnancy.

How Much Normal Values Should Be

Although the issue of AMH in women is still a subject of debate, generally accepted reference values are between 1-3 ng / dl.The AMH hormone is mainly used in women to assess ovarian capacity .At this point, the target should be to investigate and determine hormone levels, ability to produce ovums and ovarian reserves in order for the woman to become pregnant.

Can You Improve Your Egg Quality Or Your Anti

Wouldnt it be great if there were a pill or food that could improve the quality of your eggs or raise your levels of AMH?

Unfortunately, a number of supplements, like DHEA, have been touted as a possible way to boost ovarian reserve, but theres no reliable science to back up those claims.

Some have suggested that there may be a relationship between adequate levels of vitamin D and a higher AMH level, but theres no data confirming that taking vitamin D supplements increases AMH levels or improves egg quality.

The antioxidant coenzyme Q10 may show some effect on ovarian response in women undergoing IVF, but the data on whether it can increase AMH or improve egg quality is lacking.

If a woman has diminished ovarian reserve, meaning an overall lower egg count, she still may have the opportunity to have children using her own eggs it just depends on her relative level of eggs. If there are some there that we can access, typically we would do in vitro fertilization to retrieve them. A woman could also potentially bank some of the eggs retrieved. Eggs that are banked are then cryopreserved or frozen and can be used in future IVF cycles.

AMH hormone is a hormone that shows the ovarian reserves and as the age of the individual increases the ovarian reserve decreases.Decrease in ovarian reserve is irreversible, and low levels of AHM indicate that the person is progressing towards menopause.There is no known treatment for this condition.Herbal treatment, cures or medicinal plant mixtures is useless.Although there is no treatment for low AMH level, the most efficient and accurate use of time can give a chance of pregnancy even if the hormone level is low.Cryopreservation is another preferred method.

What Amh Is Not:

A predictor of whether a woman can get pregnant spontaneously in the future.

The only true test of whether a woman is able to conceive, regardless of her AMH values, is for her to get pregnant on her own. A large cohort study demonstrated that there was NO difference in pregnancy rates in women with normal AMH values trying to conceive versus women with low AMH levels trying to conceive.

If you check your AMH today and get a low number that does not mean you cant get pregnant tomorrow or in 3 months if you were to try on your own.

Just because you have normal AMH levels currently does not predict that it will stay normal for the future. All women will have a decline in fertility as they age and how rapidly that decline occurs is different for every woman and cant be predicted.

Can You Improve Low Amh Levels

Basically not. AMH is an indirect measure of the number of eggs in a woman’s ovarian reserve and there is no treatment to increase egg production. However, some women experience a slight improvement in their AMH levels by living a healthier lifestyle. Quitting smoking, eating a healthy diet or losing weight are habits that can improve the quality of the eggs, which could be reflected in the AMH level.

What Is An Amh Test

What is Good Anti Mullerian Hormone AMH level for In vitro fertilisation IVF? – Dr. Phani Madhuri

An AMH test is a simple laboratory blood test that measures the hormone levels. It requires about 3 milliliters of blood. Because AMH levels do not change during the menstrual cycle, the test can be performed on any day. Reports usually come back within a couple of hours to a couple of days, depending on where the test is being performed.

There is no special treatment or diet regimen to follow to prepare for the test. However, it can be useful to coordinate other fertility treatments that are related to the day of the menstrual cycle with the AMH test.

Can I Get Pregnant Naturally With A Low Amh Level

Low AMH values are an indication of a low ovarian reserve. However, it is only reported that the chances of pregnancy are reduced, not impossible. It depends on the exact value obtained and other factors such as the quality of the partner’s semen, the permeability of the fallopian tubes, endometrial receptivity, etc.

What Are Normal Levels Of Amh

For those who like to understand what the number signifies, here is an approximate guide to normal levels of AMH. The AMH can be measured in two different units: picomoles per litre or nanograms per millilitre . When measured in ng/mL, the measure is simple: any level over 1ng/mL shows a normal level of ovarian reserve. When measured in pmol/L normal levels are within the following ranges:

  • Age 20 29 years, 13.1 53.8
  • Age 30 34 years, 6.8 47.8
  • Age 35 39 years, 5.5 37.4
  • Age 40 44 years, 0.7 21.2
  • Age 45 50 years, 0.3 14.7

To further put these numbers into context, a level of under 4.9 indicates a level of fertility that is very low or undetectable. Levels of between 4.9 and 16.2 indicate low fertility, and a measure greater than 16.2 shows a normal level of fertility.

Relation Of Amh To Pregnancy Chances With Ivf

In general, Trolice says that the more eggs produced with IVF stimulation and retrieval, the greater likelihood for a reasonable number of good embryos to develop and transfer.

As a woman ages, the percentage of chromosomally abnormal eggs contributing to abnormal embryos increases. So, the lower the number of eggs retrieved, the less percentage of embryos, he says. While lower AMH levels do lower IVF success, Trolice says this is more prominent in women in their late 30s and beyond.

To again use our egg basket analogy to explain quantity and quality: In your 20s and early 30s, you usually have more eggs and more golden eggs. In your later 30s and beyond, you usually have fewer eggs, and fewer golden eggs.

But a young person with few eggs should still have a higher percentage of golden ones, and therefore better IVF success than an older person.

An older person can certainly luck out and have a lot of eggs left, but a higher percentage of those eggs will have lost their golden status through aging and may not result in normal embryos.

Scothchie points out that lower AMH levels are associated with:

  • lower egg yield at retrieval
  • higher risk of cycle cancellation
  • higher rates of abnormal fertilization

IVI is the largest assisted reproduction group in the world, and our experience of offering the best techniques in assisted reproduction spans over 27 years. Thanks to our services, more than 160,000 babies have so far been born. When you visit one of our clinics you will find yourself in a welcoming environment where the patient experience and needs are put at the heart of all clinical developments. We focus on turning our patients dreams of becoming parents into reality and in doing so, we always follow the consistently high standards that apply throughout our IVI clinics globally. This is the level of professional commitment and expertise that you can rely on.

In the case of low AMH hormone levels, first you could be offered an AMH and FSH test to see how well your ovaries might respond to fertility drugs. This can help your clinical adviser to judge whether IVF is the best treatment. Providing your clinical consultant at IVI considers there is an adequate AMH level for IVF, in vitro fertilisation could well be the treatment recommended. Alternatively, if the AMH levels and thus the ovarian reserve are so low that this type of treatment is unlikely to succeed, your clinician may advise you to consider the use of egg donation. Especially for women with an extremely low ovarian reserve, and if multiple rounds of IVF have not been successful, egg donation could be the best option for achieving pregnancy.

Why Do I Need An Amh Test

You may need an AMH test if you are a woman who is having difficulty getting pregnant. The test can help show what your chances are of conceiving a baby. If you are already seeing a fertility specialist, your doctor may use the test to predict whether you will respond well to treatment, such as in vitro fertilization .

High levels may mean you may have more eggs available and will respond better to treatment. Low levels of AMH mean you may have fewer eggs available and may not respond well to treatment.

You may also need an AMH test if you are a woman with symptoms of polycystic ovary syndrome . These include:

  • Menstrual disorders, including early menopause or amenorrhea
  • Excess body and facial hair growth
  • Weight gain

In addition, you may need an AMH test if you are being treated for ovarian cancer. The test can help show if your treatment is working.

What Is Amh And What Is Its Role In Female Fertility

Anti-Müllerian hormone is a substance which developing egg sacs secrete, and its levels are detectable by the simple means of an AMH blood test. The higher the number of eggs remaining in the ovaries, the higher the level of AMH which will show in the bloodstream. Therefore, a low level is considered to be a sign of a low ovarian reserve, i.e. few remaining follicles. This would be normal for a woman who is approaching menopause. By the same token, a woman who has polycystic ovarian syndrome, characterised by the presence of many small ovarian follicles, would normally be expected to show high levels of AMH.

In this way AMH plasma levels reflect the continuous growth of small follicles, and so reflect the size of the remaining follicle pool, thus representing a useful marker of ovarian reserve. Anti-Müllerian hormone is particularly useful as an endocrine marker for assessing the age-related decline of the ovarian pool and consequently its ability to predict future reproductive lifespan. It is particularly useful, although not a complete diagnostic solution, since an AMH test can be carried out at any time of the monthly cycle, and even if the woman concerned is taking oral contraceptives.

Understanding The Normal Levels Of Amh Based On Age

The Anti Mullerian Hormone, often known as AMH is a kind of a protein that is made by those cells that surround the egg. This hormone is produced mostly during the preantral stages and its production slows down as the follicles grow.

As per a recent research, the ovarian reserve of a woman is often known through the number of primordial follicles that are remaining, and these, in turn, are influenced by the growing follicles. A woman is always born with the eggs and most of them have good reproductive potential till they reach the age of 30 35 years. But, there are some who are not that fortunate. The AMH levels in the women can be used to predict the ovarian reserve and the quality of eggs. A low AMH level indicates a low chance of conceiving.

What Other Tests Can Help Determine The Ovarian Reserve

Anti-Mullerian Hormone (AMH) and Fertility

The AMH test is only one of the ways to determine ovarian reserve. Other hormones which play their part in determining fertility or lack of it include:

  • Follicle-stimulating hormone which acts on the ovarian follicles by regulating the menstrual cycle and stimulating egg cell production.
  • Luteinizing hormone controls follicle maturation. An increase in LH level acts as the signal for the ovary to release an egg cell. The LH test allows ovulation to be assessed and can determine whether a woman has reached menopause.
  • Estradiol is the most important of the oestrogens. The test for this hormone allows ovary function to be assessed. The test must be carried out between days 3 and 5 of the menstrual cycle.

In addition to the AMH measurement, testing the level of these hormones helps clinicians to evaluate a womans level of fertility and the likelihood of natural conception. Another very important function of AMH testing is that it is an important indicator of the potential effectiveness of assisted fertility treatment. This is because it provides an assessment of the likely ovarian response to hormone treatment.

Biomarker Of Polycystic Ovary Syndrome

Polycystic ovary syndrome is an endocrine disorder most commonly found in women of reproductive age that is characterized by oligo- or anovulation, hyperandrogenism, and polycystic ovaries . This endocrine disorder increases AMH levels at nearly two to three times higher in women with PCOS than in normal type women. This is often attributed to the increased follicle count number characteristic of PCOS, indicating an increase in granulosa cells since they surround each individual egg. However, increased AMH levels have also been attributed not just to the increased number of follicles, but also to an increased amount of AMH produced per follicle. The high levels of androgens, characteristic of PCOS, also stimulate and provide feedback for increased production of AMH, as well. In this way, AMH has been increasingly considered to be a tool or biomarker that can be used to diagnose or indicate PCOS.

Biomarker Of Turner Syndrome

Turner syndrome is the most common sex chromosome-related inherited diseases in female around the world, with the incidence of 1 in 2000 live female births. One of the significant pathological features is the premature ovarian failure, leading to amenorrhea or even infertility. Follicle stimulating hormone and inhibin B were recommended to be monitored routinely by specialists to speculate the condition of ovary. Recently, anti-Müllerian hormone is advised as a more accurate biomarker for follicular development by several researchers. The biological function of anti-Müllerian hormone in ovary is to counteract the recruitment of primordial follicles triggered by FSH, reserving the follicle pool for further recruitment and ovulation. When menopause takes place, the serum concentration of anti-Müllerian hormone will be nearly undetectable amongst normal women. Thus, variations in AMH levels during childhood may theoretically predict the duration of any given girl’s reproductive life span, assuming that the speed of the continuous follicle loss is comparable between individuals.

Anti Mullerian Hormone Function

The very first immunoassay for AMH was developed way back in 1990. From that year AMH is being treated as the main factor to analyze womans ovarian reserve. The Anti Mullerian Hormone test helps to determine the number of pre-antral follicles that are present ovaries. This is why AMH plays a very important role in the health of womans reproductive health.

What Does An Amh Test Actually Mean

Amh test

Since AMH is only secreted by follicles that have started to develop but that are less than 9 mm in size, the information provided by this test is limited. Therefore, AMH is only a reflection of how many follicles are in the early stages of development. A normal AMH can indicate that there are a normal number of follicles in development between resting and 9 mm. A high AMH can indicate more than average egg follicles in this stage. Women with PCOS can have a high AMH because their follicles are stuck in the early stages of development due to the hormonal imbalances that accompany PCOS.

Can Amh Values Increase From One Test To The Next

La hormona antimulleriana es una hormona cuyo valor se puede determinar en una analítica de sangre para valorar la reserva ovárica de la mujer. Esta hormona es producida por los folículos antrales, por lo que es proporcional al recuento de folículos antrales y al número de óvulos que podremos conseguir en una estimulación ovárica.

En general, se considera que la AMH es el parámetro más fiable a la hora de valorar la reserva ovárica. Sin embargo, a veces nos encontramos que los valores difieren entre una extracción y otra, e incluso nos podemos encontrar con incrementos de su valor con el tiempo. Este aumento no va en relación con un aumento en la reserva ovárica, ya que esta disminuye con el paso del tiempo.

La AMH puede tener una gran variabilidad debido a factores como los cambios estacionales, el momento del ciclo, el consumo de tabaco o determinadas enfermedades. En un estudio que valoró la variabilidad de la AMH en diferentes días del ciclo encontró una media de variación de hasta un 20%, siendo mayor en aquellas mujeres con niveles bajos de AMH.

Por ello, se debe siempre contrastar la información dada por la AMH con una ecografía de recuento de folículos antrales, y ser cautos a la hora de interpretar una única determinación de AMH, sobre todo en caso de mujeres con baja reserva ovárica.
