Secondary cervical perforation by the Copper-T intrauterine device.

Five cases of cervical perforation have been observed in women with a Copper-T IUCD, over a period of 5 yr. In all cases, the distal end of the stem (vertical limb) of the T had perforated through the cervical wall into one of the fornices of the vagina. Only 2 cases had symptoms leading to the discovery of the device, while the other 3 were discovered accidentally or on routine examination.
