Cervical LEEP knife on the cervix of women who have not given birth may affect the future pregnancy and delivery, in the case of women who have no childbearing requirements will have no effect in the future. Cervical LEEP knife surgery, also known as cervical conical resection surgery, is to remove the cervical tissue with the cervical opening as the center, mainly used for the treatment of deeper cervical erosion, cervical intraepithelial lesions and other diseases. The treatment can damage the inside of the cervical canal, and if the lesion is extensive, it can result in a shorter cervix. If a fertile woman becomes pregnant after cervical conization, at the end of pregnancy, with the gradual growth and development of the fetus and its appendages in the uterine cavity, the length of the cervix gradually shortens and the pressure gradually increases, making it easy for cervical insufficiency to occur, resulting in the risk of miscarriage and preterm delivery. It is recommended that patients go to the Obstetrics and Gynecology Department of a regular hospital, where a professional physician will give them an appropriate treatment plan based on their individual situation.
