Antral Follicles are normally between 2 and 8 millimetres in size when viewed during an ultrasound scan. The numbers of these follicles is related to the cohort of all follicles within the ovary. Reproductive ageing is closely associated with the quantity and quality of the pool of follicles in the ovaries. An Antral Follicle Count combined with an AMH blood test has become powerful and more meaningful tool for the assessment of reproductive potential.
|Antral Follicle Count||Ovarian Fertility Potential||AMH pmol/L|
|0-7||Very low / Undetectable||Less than 4.9|
|8-15||Low Fertility||4.9 – 16.2|
|Above 15||Normal Fertility||Greater than 16.2|
The table above shows the levels of AMH and how they are related to Fertility Potential and Antral Follicle Counts
