PIP: 30 days following the normal insertion of a Copper 7 IUD in a patient with a gravidity of 1 and a parity of 0, a routine follow-up check revealed that the IUD string was protruding through the exocervix 6mm away from the os. The patient was asymtomatic. Examination prior to the insertion revealed a normal genital tract. The IUD was inserted with release technique. The IUD was removed upon request of the patient. The perforation was perhaps related to the curved memory which the string develops while wound around the inserter tip. It is unlikely that this problem could produce serious complication; however, the risk of infection could be enhanced. Retraction of the string of Copper 7 IUDs into the uterus was observed previously.
