If a woman develops a loose cervical opening, it is mainly due to congenital dysplasia or cervical laceration, and is related to cervical damage caused by factors such as transvaginal delivery, induction of labor and miscarriage. In some women, due to multiple pregnancies, the cervix is easily damaged during the delivery process. Some women who have a large pregnancy, such as abortion in the third trimester, need to use a forceps scraper to damage the cervix more seriously, which can easily cause cervical laxity. Some women have induction of labor and IUD surgery, etc., which can easily damage the cervix and cause cervical laxity. If there is no discomfort, there is no need to worry. If you do not plan to have children, you should take good contraceptive measures to avoid unwanted pregnancies and abortions or induced abortions that cause loosening of the cervix.
