The Anti-Mullerian (AMH) is a protein hormone produced by the cells in the ovaries. The more ovarian follicles (a sac containing an immature egg) a woman has, the more AMH hormone her ovaries will produce. Measuring the levels of this hormone in a woman’s blood can be a good way of measuring her ovarian reserve – a concept that determines fertility by the number of eggs available in the ovaries.
An anti-mullerian hormone test (AMH) is a marker for ovarian egg reserve assessed via a blood test. As your AMH levels do not change during your menstrual cycle, the test can be taken at any time of the month – even if you are taking oral contraception.
You should consider getting an AMH test if:
A woman is born with all the eggs she will ever have, which is typically around 1-2 million. By puberty, its usually halved – and every month after than she loses up to 1,000 eggs. Of those eggs, only one (or two) is matured and ovulated each month. Not only does ageing mean fewer eggs, but egg quality is also diminished over time. This is a result of the exposure to illness, toxins, free radicals, fever and more throughout her life – damaging the DNA inside her eggs. It is a natural and inevitable part of ageing.
A woman’s chance of natural pregnancy drops from around 25% at age 25 to less than 5% at the age of 40.
