For an IUD, it usually takes 3-5 minutes. However, due to different anesthesia methods, the time for IUI will vary. For example, for painless IUI, a series of checkups are needed before painless IUI, such as electrocardiogram, immunity five, coagulation four, blood routine, leukorrhea routine and so on, and it may take 2-3 hours for the checkups. Local anesthesia, not as tedious as painless abortion, but it has to check the routine of leukorrhea, and this takes half an hour. When the IUD begins, the body is positioned in the truncated position, the vagina is dilated, the cervix is exposed and the IUD is placed in the uterine cavity. When the placement in the uterine cavity is over, the entire IUD procedure may be over. The entire time is relatively short, which is 3-5 minutes time. If you are not sensitive to pain, you can opt for local anesthesia. If you are particularly sensitive to pain, you can opt for a painless IUD.
