Accredited fertility clinics are among companies misleading women about a blood test used to indicate fertility, resulting in women potentially making misinformed health decisions, researchers say.

Dr Tessa Copp, from the University of Sydney’s school of public health, says she and her colleagues are concerned by an increasing number of advertisements that overstate what the anti-Müllerian hormone (AMH) test is useful for.
