Low AMH levels – Causes, Symptoms & Treatment
                     Low AMH levels – Causes, 
Symptoms & Treatment
Low AMH Levels (Overview)
Anti-Müllerian Hormone (AMH) is a hormone produced by the developing follicles in the female ovaries. AMH decreases as the 
age of the women increases naturally. Women have commonly low AMH results over the age of 40. This implies that the ovarian 
reserve in women diminishes. Although many factors are considered to assess the accurate levels of AMH especially including 
age, the reference range for AMH value should be within 2.20 – 6.80 ng/mL. There are no definite ways to increase the AMH 
levels but various things can be tried.
Low AMH and pregnancy are often discussed simultaneously. This is because low AMH levels signify the decreased number of 
eggs or very low number of eggs in the ovarian reserve. And depleted eggs in ovarian reserve implies the meagre chances of 
getting pregnant.
However there are various differentiating factors such as different labs may give different results and now it is also recognized 
that AMH varies during the cycles also.
Causes of Low AMH Levels
There can be several causes for a low AMH level. Let us discuss some of them below:
● Age: The most influential factor that causes the change in AMH levels. All the women possess the supply of immature 
eggs for their lifetime right at the time of birth. These eggs get mature and are used during the ovulation cycles 
throughout the lifespan of the women till the time of menopause. The ovarian reserve decreases with the time, so the 
AMH level starts decreasing as she gets older. Till the time women ages to the mid or late 30s, the number of eggs in 
the ovarian reserves starts reducing. That’s why fertility decreases as AMH starts depleting around the age of 35.
● Poor Diet: A diet consisting of processed food and excess fat is never a good option for a healthy AMH level. The 
unhealthy intake of food results in obesity which causes various reproductive issues including low AMH levels. Also, 
some studies show that Vitamins deficiency especially Vitamin D directly impacts the AMH levels and fertility. So, it is 
advised to consume a balanced diet to have ideal levels of AMH.
● Past Medical Record: Another factor causing low AMH levels apart from age is medical history. Medical circumstances 
can affect the AMH levels irrespective of the age. There are instances where some women face low levels of AMH even 
in their 20s and 30s while others continue to possess high AMH levels a few years after their 30s.
● The experience of adverse medical conditions related to the reproductive system like hormonal disorders also impacts 
the AMH level causing its decrease. Also, the women with a previous history of ovarian surgery due to the conditions 
like ovarian cysts, endometriosis and ovarian torsion, etc., have a greater chance of having low levels of AMH.
● Mental and emotional health: The next cause of a low AMH level is stress. A healthy mind and emotional well-being 
are always beneficial particularly for the women who are trying to conceive. Living with mental pressure or hyper stress 
continuously may result in failure to conceive. Moreover, de-stressing and maintaining a peaceful mind can correct the 
AMH levels.
Other factors that may cause low levels of AMH are:
❖ Inherited genetic disorders
❖ Cancer treatment
❖ Autoimmune attack on ovaries
❖ Other Environment causes
❖ Low AMH Level Symptoms
Though, there are no specific or clear symptoms of low levels of AMH, getting done an AMH blood test when 
women notice a short cycle, irregular periods or premature menopause.
❖ How low is too low AMH Level?
AMH levels tend to decrease with age of a woman. So, the answer to “how low is too low AMH level” varies 
from age to age. But a too low AMH score can be defined as a level which poses a health threat or indicates 
possible infertility in a woman where even an Assisted Reproduction Technology has a slim chance of 
success.
First, let us look at the list of ideal AMH 
levels according to the ages.
