What is AMH?
AMH is a blood test used to assess ovarian reserve. AMH is made in the ovarian follicles, which contain eggs, and its levels can be checked at any time during the menstrual cycle. Blood levels of this hormone are measured to assess the remaining ovarian reserve (egg supply) in your ovaries.
How is an ‘AMH’ test result used?
This result will be used to help decide which treatment protocol you will follow during treatment. We will also use it to counsel you on how likely you are to respond to certain treatments, such as hormonal stimulation during IVF.
A high AMH level raises the possibility that you may over-respond to your treatment (i.e. too many eggs will be produced), increasing the risk of ovarian hyperstimulation syndrome (OHSS). Ovarian hyperstimulation syndrome (OHSS) | RCOG
A low AMH level raises the possibility that you may respond poorly, or not at all, to hormonal stimulation. This means a low number of eggs, or none, may be produced.
AMH is not used to decide if you’ll be offered treatment.
