Anti-Mullerian Hormone (AMH) Testing

AMH can be measured at any time in the menstrual cycle as it is stable throughout the cycle. It is a marker for ovarian (egg) reserve and is assessed via a blood test.

For accurate assessment, AMH tests should be combined with an antral follicle count – AFC (number of small follicles within both ovaries). AFC is done using an expert fertility (transvaginal) ultrasound scan. CREATE pioneered advanced ultrasound techniques, providing us with an extremely accurate assessment of your fertility. Find out more about our advanced scanning.

What is AMH and what does it mean for fertility?

Anti-Mullerian Hormone (AMH) is a protein hormone produced by cells within the ovary. Understanding your AMH level can help to assess your ovarian egg reserve and therefore your fertility.

AMH levels are naturally lower in older women (particularly over the age of 40) and higher in women with Polycystic Ovaries (PCO) or Polycystic Ovary Syndrome (PCOS).

What if I have low AMH?

If you have very low AMH levels, you are likely to respond poorly to the drugs involved in conventional, stimulated IVF. However, Natural/Modified Natural IVF treatment can be used as an alternative.

CREATE pioneered Natural and Modified Natural IVF treatments to enable women to have a baby with their own eggs if AMH levels are low as long as the woman is ovulating. At CREATE we will treat any woman under the age of 50 with her own eggs if at all possible and have a long history of good success rates with these patients, in 2011 our success rates were as follows:

  AMH level Success rate 
AMH <2.84 pmol/l 10.5%
AMH 1.2-2.84 pmol/l 16.35%
AMH 1.0-2.84 pmol/l 14.3%

If you’re worried about low AMH results and the implications on your fertility it is important to discuss these concerns with a specialist, if you would like to arrange a consultation with one of our fertility experts, please contact us.

Natural IVF involves no stimulating drugs, find out more about Natural IVF.

Modified Natural IVF involves minimal daily doses of stimulation drugs, if ovarian stimulation is necessary. The daily dosage of stimulating drugs and protocol can be tailored depending upon the level of AMH in blood.

Reducing the number of drugs given to women with low AMH levels can reduce the risk of Ovarian Hyper Stimulation Syndrome (OHSS) which is a potentially fatal side effect of high levels of stimulating drugs. CREATE’s commitment to patient safety and reduces unnecessary medication means we have never had a patient with a serious case of OHSS.

To discuss which type of treatment might be suitable for you or to have your AMH levels tested, please contact us to arrange an appointment.
