The depth of the cervix is different for women at different times. For women of normal childbearing age, a cervical length of between 2.5 and 3cm is normal.
The size of the uterus varies greatly at different stages of development, and the depth of the cervix is not always the same. Generally speaking, the cervical depth of a normal woman of childbearing age is 2.5 to 3 cm when she is not pregnant, but due to individual differences, the cervical length of different women may vary.
However, due to individual differences, the cervical length may vary from woman to woman. Since the normal cervical depth of a woman of childbearing age is 2.5 to 3 cm in an infertile state, if the cervix is too long or too short, it may lead to cervical insufficiency, and the patient may suffer from preterm labor and miscarriage after pregnancy, so it is recommended to consult a medical professional for details.
