OBJECTIVE: To understand the removal of IUD and its useful life in perimenopausal and postmenopausal women. Methods: A cross-sectional survey of 45-60-year-old women living in the district of Huangpu and using contraceptive methods for the last time as IUDs was conducted during the period from August 2011 to December 2011. A total of 2,167 people were surveyed, of which 2,054 were included in the analysis. Results: The average age of the subjects was 52.4 ± 4.0 years. Among the 160 women who had already had menopause, 63 cases (5.4%) had not taken IUD, of which 15 cases had IUD placed more than 5 years after menopause. The mean intrauterine placement time of IUD was 18.9 ± 5.7 years, 50.2% IUD users placed intrauterine time> 20 years. Among 732 non-menopausal women, the average useful life of IUD was 17.3 ± 5.7 years, and 51.1% of women used IUD beyond the recommended period of use. Conclusion: Post-menopausal IUD expired in serious use, and a significant portion of the IUDs in use have expired.
