AMH Levels – What do they mean?

Dear Professor Winston,
I was fortunate enough to have IVF treatment at the age of 20 after losing both of my Fallopian tubes and having an AMH Score of 4. I was told that if I waited too long that I would probably be menopausal. I am now 23 and the proud mother of my 2 year old miracle, however I still suffer with a lot of abdominal pain which has been investigated several times.
In October 2014, I asked for another AMH test – the results came back at 19, more than 4 times the original score. This was performed again and it came back at 21, and again, this time 27. All these tests were conducted in the same lab as my original tests and have all been double checked so there has been no mistake. After being told my fertility would never get better, I have now been told that I have normal fertility. I have recently been diagnosed with PCOS however I have been told that this is not what’s causing my AMH to increase.
I have been for several different opinions now and I am at my wits end! Please can you shed some light on whether the increase in AMH, PCOS and my continuous pain should be something to be concerned about and whether it is actually possible that I have normal fertility?
Thank you. S

Dear S,

If you review this website and also my book The Essential Fertility Guide, you will see that AMH levels are not absolute proof of fertility or infertility and that the levels also vary considerably depending on which lab does the assay, how the assay is processed, and indeed how the blood sample is stored.

Also people with PCOS do tend to have elevated levels of this hormone. You say you have pain. Have you had a laparoscopy?

Best wishes
