Q1: Will I lose points on an OSCE or medical board exam for using the "wrong" pronunciation?
A1: No. Standard medical examiners throughout the US, Canada, the UK, and Australia recognize both /duːˈɑːdənəm/ and /ˌdjuːoʊˈdiːnəm/ as valid standard English. Evaluators focus on clinical accuracy, not regional phonetic variation.
Q2: Why do some older American doctors use the British "doo-oh-DEE-num" variation?
A2: Until the mid-20th century, many American medical textbooks and professors adhered closely to classical Latin quantities. Older physicians trained under faculty who favored the Latin long vowel on the third syllable, preserving that habit throughout their careers.
Q3: How do you pronounce the adjectival form "duodenal"?
A3: The adjectival form shifts stress back to the third syllable in nearly all regions: /ˌdjuːəˈdiːnəl/ or /ˌduːəˈdiːnəl/ (doo-oh-DEE-nul), as in "duodenal ulcer." Even speakers who say "doo-ODD-uh-num" for the noun frequently switch to "doo-oh-DEE-nul" for the adjective.
