Low AMH Levels: How They Affect Your Fertility

Almost no other hormone in your body can give as much information about your reproductive potential as Anti-Mullerian Hormone (AMH). Because AMH is one of the greatest lab indications we have for ovarian reserve or the number of eggs in your ovaries, it’s a good place to start.

AMH levels aren’t a predictor of your capacity to conceive now or in the future. However, a blood test can help you comprehend the prospective consequences of treatments such as egg freezing and in-vitro fertilisation (IVF), as well as lead you toward indicators that may predict early menopause.

What is AMH?

Although AMH is generated in both male and female reproductive organs, it is more commonly tested in females. This is because AMH is produced by the follicles that mature in a woman’s ovaries. The main idea here is that the more eggs you have, the higher your AMH levels will be, and vice versa. Therefore, AMH levels are evaluated before IVF since the results help clinics assess ovarian reserve and prepare for procedures and medicines.

It’s crucial to understand that AMH levels are a good predictor of how many eggs are left, but they’re not a good indication of the quality of the eggs being produced.

What is Considered a Low AMH?

The level of AMH in your system might indicate how ‘active’ your ovaries are. As you become older, your natural pool of possible eggs starts to reduce, and as a result, fewer preantral follicles are created, resulting in fewer AMH. AMH levels that are low might indicate a limited pool of viable eggs.

Low AMH levels do not cause or suggest infertility; rather, they are a warning that the pool of available eggs is diminishing. The possibility of one growing, being released, and being fertilised falls as the number of possible eggs in the ovaries drops.

Your ovaries will be stimulated throughout fertility therapy in an attempt to encourage these preantral follicles to continue to develop and generate an egg. Instead of collecting 1-2 eggs every month, we may boost growth and perhaps gather more.

What Causes Low AMH?

Low AMH is often caused by both biological and medicinal factors-

  • For starters, AMH levels fall with age in every female because the ovarian reserve (or residual egg supply) reduces over time.
  • Endometriosis, a disorder in which uterine tissue develops in other places of the body, can also cause AMH levels to be lower.
  • Other research has looked into genetic variables, including genetic polymorphisms that may cause low AMH.
  • Rheumatoid arthritis, lupus, and thyroid disorders are all autoimmune disorders that produce persistent inflammation and reduce AMH levels.
  • Certain cancer treatment regimens can cause egg loss, and fewer eggs mean less AMH production.

What Are the Symptoms of Low AMH?

Low AMH has no physical signs that we are aware of, so you can’t make any assumptions about your levels without testing them. However, when it comes to fertility and reproductive health, low AMH might create certain problems in the body:

Shortened Reproductive Window: If a woman’s ovaries have low levels of AMH (below what’s “normal” for their age group), it might suggest that their reproductive window is getting shorter.

Primary Ovarian Insufficiency: POI is defined by undetectable AMH levels before the age of 40. If your AMH test results show very low or undetectable amounts of AMH and you’re under the age of 40, consult your doctor about POI; it might be linked to cardiovascular and bone health issues.

Diminished Ovarian Reserve: If you’ve been diagnosed with DOR, it implies that you have fewer eggs than you should have at your age. When compared to someone with a higher AMH, you may have fewer reproductive years ahead of you (making building a family of your ideal size more challenging), and egg freezing or IVF may be less successful for you.

Low AMH- Effect on Fertility

You will ovulate one egg every month as long as you have a few follicles. You’ll have the same pregnancy rate as a woman in the same age group who has a high AMH. The reason for this is that a woman’s ovary will grow and ovulate one egg every month, regardless of her AMH level. The total number of eggs in the ovary has no bearing on this.

However, because low AMH levels are linked to a shorter reproductive window, you should think about how this could affect your plans for children, both in terms of when you start having them and how many you want. If you want to put off having children, egg freezing or embryo freezing might be a good option.

How Can We Help?

In any case, if you’ve been diagnosed with low AMH, you should see a reproductive doctor right away. This ensures that you receive advice based on your results and circumstances. As previously stated, certain cases of the decreased ovarian reserve may reveal another underlying medical issue.
