It is often described as "blind", meaning that it is a duct that does not lead to any other structures. [3] It tends to be about one cm in length. [4] It can sometimes be enlarged. [5] [6] The utricle is deemed enlarged if it allows insertion of a cystoscope at least 2 cm deep. [7] This is often associated with hypospadias. [8]
Lactiferous ducts are ducts that converge and form a branched system connecting the nipple to the lobules of the mammary gland. When lactogenesis occurs, under the influence of hormones, the milk is moved to the nipple by the action of smooth muscle contractions along the ductal system to the tip of the nipple.
Breastfeeding infant. Blocked milk ducts are a common breastfeeding problem and can be caused due to a number of reasons: [2] [4] When the infant does not latch properly; Wearing a tight bra or tight clothing can restrict the breasts and put pressure on them leading to a blocked milk duct; A bad or weak pump could lead to a drainage issue
Since one of the most prominent symptoms is tension and engorgement of the breast, it is thought to be caused by blocked milk ducts or milk excess. It is relatively common; estimates range depending on methodology between 5–33%. However, only about 0.4–0.5% of breastfeeding mothers develop an abscess. [8]

[1] [2] Mammary alveoli are the site of milk production and storage in the mammary gland. [1] [2] Mammary alveoli cluster into groups called mammary lobules, and each breast may contain 15 to 20 of these lobules. [1] [2] The lobules drain milk through the lactiferous ducts out of the nipples. [1] [2]
