Women who have not had children can also have an IUD, but it is recommended that they choose another form of contraception, such as a condom. The IUD, also known as the ring, is a relatively effective form of contraception. A history of childbearing is not a contraindication to the IUD, so it is possible to use the IUD as a contraceptive. However, for women who have never given birth, because the cervix is relatively tight, it is necessary to explore the uterine cavity and then dilate the cervix appropriately before the IUD can be inserted, and this process will be more painful. Moreover, the uterus of childless women is more sensitive to foreign objects such as IUDs, and the uterus will produce contractions, which will increase the probability of IUD dislodgement. It is generally not recommended that women who have not given birth choose the IUD for contraception, but can choose condoms and other contraceptive methods, which also have better results.
