Objective: To determine whether the insertion of a copper intrauterine device can restore regular menses in patients with functional secondary amenorrhea.

Design: Prospective, observational study.

Setting: Clinical practices.

Patient(s): Forty-eight volunteers with functional secondary amenorrhea.

Intervention(s): Insertion of a copper intrauterine device.

Main Outcome Measure(s): Restoration of menses.

Result(s): In 40 patients, regular menses were restored within a few weeks after insertion of the device. Normal menses were maintained as long as the copper intrauterine device remained in place. After removal of the device, normal menses persisted for 1 year.

Conclusion(s): Insertion of a copper intrauterine device restores regular menses in women with functional secondary amenorrhea. The mechanism of action of the device probably is related to the release of prostaglandins from the endometrium.

Pregnancy complications pose challenges for both pregnant women and obstetricians globally, with the pathogenesis of many remaining poorly understood. Recently coined as a mode of cell death, cuproptosis has been proposed but remains largely unexplored. This process involves copper overload, resulting in the accumulation of fatty acylated proteins and subsequent loss of iron-sulfur cluster proteins.

Introduction: IUDs are effective, reversible and safe methods of contraception. The mechanism of action of IUDs as a group is inducing endometrial atrophy, apoptosis, altering tubal motility; preventing sperm permeability, fertilization, and implantation. Complications of IUD include menstrual disturbance, pelvic pain, and increased risk of ectopic pregnancy with contraceptive failure, device expulsion, uterine perforation or transmural migration with misplacement of the device.

We present a rare case involving a 25-year-old woman who had fragmentation of a copper intrauterine contraceptive device (IUD) while still within its recommended lifespan. The patient's symptoms included lower abdominal pain, offensive vaginal discharge, and the passage of copper IUD fragments. The pelvic examination confirmed the presence of the copper IUD strings, and with her consent, the device was removed.
