The word "deferentitis" is a medical term used to describe inflammation of the deferent duct. Its spelling can be explained using the International Phonetic Alphabet (IPA) as /ˌdɛfərənˈtaɪtɪs/. The stress falls on the second syllable "ren," while the "e" in "deferent" is pronounced as "uh," and "tis" is pronounced as "tis." The word is a combination of the Latin word "deferens" meaning carrying away, and "-itis," a suffix used to denote inflammation. Deferentitis is a rare condition that can lead to infertility if left untreated.
