An express consent is one where the terms are stated in distinct and explicit language. Express consent can be given orally or in writing. Though both of these are of equal value, written consent is considered superior as it has an evidential value (Indian J Urol 2009 Jul;25(3):372-8). Except for the circumstances where consent can be clearly and obviously implied, there should be express consent. Express consent should be obtained for treatments that involve risk or involve more than mild discomfort or when it is capable of diminishing a bodily function.
