What is AMH?
AMH stands for anti-Müllerian hormone, which is a protein produced in your ovaries. The amount of AMH in your blood is proportional to the number of eggs your ovaries can produce, which is a good indicator of your current fertility.
What are ovarian follicles?
Ovarian follicles are small fluid-filled sacs that develop eggs in your ovaries. Each follicle contains a single egg, which is released when you ovulate. You’re born with a set number of ovarian follicles, which falls naturally as you age, and your body can’t make any more.
Ovarian follicles release AMH, which is why AMH levels can be measured to check your fertility. Higher AMH levels are usually a sign that you have more ovarian follicles remaining, which increases the chances that you will release a healthy egg.
How many eggs do women have?
You’re born with around a million ovarian follicles, which falls to around 300,00 by the time puberty starts. However, you’ll normally release one egg each cycle, and not every follicle will become a viable egg. Over your lifetime you’ll release around 300 to 400 eggs that can be fertilised.
