Definition of lactiferous in English:



  • Forming or conveying milk or milky fluid.

    ‘lactiferous ducts’
    • ‘However, if the implant is placed on top of the pectoral muscle, it can exert pressure on the lactiferous ducts and glands, which will reduce lactation.’
    • ‘An example is the inferior pedicle technique, in which the areola and nipple are moved while attached to a mound of tissue, called a pedicle, that contains the still-connected lactiferous ducts and nerves.’
    • ‘It is produced in the cytoplasm of lactiferous cells along with amino acids, phospholipids, carbohydrates, and proteins.’
    • ‘The ducts are somewhat larger just behind the nipple where they form lactiferous ampulla which accumulate breast milk during and just prior to breast feeding.’
    • ‘If a surgical procedure is necessary, care should be taken to preserve breast function by using a radial incision, which has less chance of severing the nerve supply or lactiferous ducts than the usual circumareolar incision.’


Late 17th century: from Latin lac, lact- ‘milk’ + -ferous.
