AMH testing rises sharply among women in Australian general practice
11 Sep 2026
A Flinders University study examined health records from almost 1.4 million women aged 20–44 who attended Australian general practices during the 10-year period. AMH testing among women aged 30–34 increased almost 20-fold.
The researchers found large differences between practices. Around one in 10 practices had no patients who received an AMH test during the study period.
About 20% of women received a result classed as low. However, among women who repeated the test after receiving a low result, one-third later had a result within the normal range.
Lead author Associate Professor Luke Grzeskowiak said AMH can provide information about ovarian reserve, but it cannot predict whether a healthy woman will become pregnant, how long conception may take or how much reproductive time she has remaining.
A low AMH result does not mean a woman is infertile, while a normal result does not guarantee future fertility.
The researchers said AMH testing may have a role in some specialist fertility settings, but it should not be used as a general test to predict a woman's chances of having a baby.
The rise in testing may be linked to delayed childbearing, greater awareness of fertility issues, social media messages and commercial promotion of AMH testing as a way to assess reproductive potential.
The researchers also raised concerns about the possible psychological impact of test results. A low result could lead some women to bring forward decisions about having children, while a normal result could create false reassurance when other fertility factors may be present.
They said further research is needed to understand what is driving the increase in AMH testing and to support evidence-based use of the test in clinical practice.
