In prepubertal girls, the functional squamocolumnar junction is present just within the cervical canal. [17]: 411 Upon entering puberty, due to hormonal influence, and during pregnancy, the columnar epithelium extends outward over the ectocervix as the cervix everts.
The cervical canal is generally lined by "endocervical mucosa" which consists of a single layer of mucinous columnar epithelium. However, after menopause, the functional squamocolumnar junction moves into the cervical canal, and hence the distal part of the cervical canal may be lined by stratified squamous epithelium (conforming to a "type 3 transformation zone").
Cervical ectropion is a normal phenomenon, especially in the ovulatory phase in younger women, during pregnancy, and in women taking oral contraceptive, which increases the total estrogen level in the body. [2] It also may be a congenital problem by the persistence of the squamocolumnar junction which is normally present prior to birth.
