In cases of cervical weakness, dilation and effacement of the cervix may occur without pain or uterine contractions. In a normal pregnancy, dilation and effacement occurs in response to uterine contractions. Cervical weakness becomes a problem when the cervix is pushed to open by the growing pressure in the uterus as pregnancy progresses.

Cervical pessary is a medical device used to treat an incompetent (or insufficient) cervix (cervix starts to shorten and open too early). Early in the pregnancy a round silicone pessary is placed at the opening to the cervix to close it, and then it's removed later in the pregnancy when the risk of a preterm birth has passed.
A McDonald cerclage, described in 1957, is the most common, and is essentially a pursestring stitch used to cinch the cervix shut; the cervix stitching involves a band of suture at the upper part of the cervix while the lower part has already started to efface. [2] This cerclage is usually placed between 16 weeks and 18 weeks of pregnancy.
Some additional uses for pessaries are for an incarcerated uterus, prevention of preterm birth and an incompetent cervix. [3] [10] In early pregnancy the uterus can be displaced, which can lead to pain and rectal and urinary complications. [3] A pessary can be used to treat this condition and support the uterus. [3]
Cervical canal widening can be temporarily achieved by the insertion of dilators into the cervix. If the stenosis is caused by scar tissue, a laser treatment can be used to vaporize the scarring. [5] Finally, the surgical enlargement of the cervical canal can be performed by hysteroscopic shaving of the cervical tissue. [6]
Asherman's syndrome (AS) is an acquired uterine condition that occurs when scar tissue forms inside the uterus and/or the cervix. [1] It is characterized by variable scarring inside the uterine cavity, where in many cases the front and back walls of the uterus stick to one another.
