AMH Levels – What They Mean and What They Don’t

AMH or Antimullerian Hormone is a useful test to run for specific reasons. It can also be confusing and stressful if the levels are misunderstood or taken out of context. Let’s take a look at how can use AMH testing to understand more about PCOS, Fertility, Perimenopause and Hormones. 
The Main Reasons To Run Levels of  AMH:
🔎To understand fertility and assist in decisions around fertility treatments and egg freezing
🔎 To clarify around a diagnosis of PCOS
🔎 To understand if symptoms are caused by premature ovarian insufficiency (early onset perimenopause  or menopause)
AMH levels decrease with age and should always be looked at with respect to age.

It is normal to have high levels of AMH in younger years and for levels to decline significantly by a patient’s 40s.

Low AMH Levels MIGHT Mean:
  • A lower egg reserve
  • Recent or current birth control pill use
  • Inflammatory reproductive conditions like endometriosis
  • Autoimmune diseases (thyroid in particular)
  • Premature ovarian insufficiency (early perimenopause and symptoms in younger patients)
Low AMH Levels DO NOT Mean
  • You can’t conceive
  • Menopause is imminent. Depending on age, it can still take many years to occur even with low AMH
High AMH Levels MIGHT Mean
An excellent ovarian reserve
  • PCOS
  • Younger age
  • IVF cycles might cause ohss
  • In PCOS IVf cycles might produce a large number of eggs however quality is the issue (empty follicles, many eggs and embryos arrest).
High AMH does NOT mean
  • You can’t conceive
  • Your PCOS will always be this way – high AMH will naturally improve with age and proper treatment
