Normally, the cervix should be at least 30 mm in length. Cervical weakness is variably defined. However, a common definition is a cervical length of less than 25 mm at or before 24 weeks of gestational age. The risk of preterm birth is inversely proportional to cervical length: [7] Less than 25 mm; 18% risk of preterm birth
Obstetric sonography is useful in the assessment of the cervix in women at risk for premature birth. A short cervix preterm is associated with a higher risk for premature delivery: At 24 weeks' gestation, a cervix length of less than 25 mm defines a risk group for spontaneous preterm birth. Further, the shorter the cervix, the greater the risk ...
The term postterm pregnancy is used to describe a condition in which a woman has not yet delivered her baby after 42 weeks of gestation, two weeks beyond the usual 40-week duration of pregnancy. [160] Postmature births carry risks for both the mother and the baby, including meconium aspiration syndrome, fetal malnutrition, and stillbirths. [161]
Cervix with a bluish-violet discolouration. Chadwick sign is a medical clinical sign characterised by the bluish-violet discolouration of the mucous membranes of the vulva, vagina (particularly on the anterior vaginal wall), and the cervix, resulting from venous congestion due to increased blood flow as part of the maternal physiological changes in pregnancy.
Pain occurs in about 20 to 70 percent of men with Peyronie’s disease during the acute phase. Shortening or narrowing of the privates. In severe cases, some men lose around 0.5-1.5 cm of length ...
The cervix is more tightly connected to surrounding structures than the rest of the uterus. [7] The cervical canal varies greatly in length and width between women or over the course of a woman's life, [3] and it can measure 8 mm (0.3 inch) at its widest diameter in premenopausal adults. [8] It is wider in the middle and narrower at each end.
Bloody show or show is the passage of a small amount of blood or blood-tinged mucus through the vagina near the end of pregnancy.It is caused by thinning and dilation of the cervix, leading to detachment of the cervical mucus plug that seals the cervix during pregnancy and tearing of small cervical blood vessels, [1] and is one of the signs that labor may be imminent.

Development of the female reproductive tract begins at approximately week 8 of embryonic development, and development of the Müllerian duct system is typically complete by the end of the first trimester. [8] [29] The Müllerian ducts develop to give rise to the fallopian tubes, uterus, cervix and upper two-thirds of the vagina.
