“…The observation that age is related to the risk of expulsion confirms what has been reported by others [6,8]. The finding of no apparent relationship between the length of the uterine cavity (external os to fundus) and the risk of expulsion is consistent with the results reported elsewhere [9,10].…”

The Stainless Steel Ring, Uterine Cavity-Shaped Device, TCu220C and MLCu375 IUDs were evaluated in a randomized trial of 1536 women in Guangdong Province, China. The first-year continuation and expulsion rates were significantly lower (p less than 0.05) for the latter 3 IUDs than for the Stainless Steel Ring. The first year pregnancy rates for the MLCu375 (0.76 per 100 women) and TCu220C (1.2 per 100 women) were significantly lower (p less than 0.05) than those of the other two devices (6.1 and 4.1 per 100 women). The results of the study show that the MLCu375 and TCu220C are the most suitable IUDs for women in Guangdong Province.

“…Los estudios incluidos en una revisión de estudios observacionales (186), con seguimientos entre los 6 y 48 meses, también mostraron que los embarazos eran infrecuentes (188)(189)(190)(191)(192)(193)(194)(195). La tasa acumulada de embarazo varió del 2% a los 6 meses de seguimiento (193) hasta el 11% a los 48 meses (191).…”

“…26 However, in another study of the copper IUD, removal rates for bleeding and pain at 24 months were no different for adolescents compared to adults. 27 In a UK study of nulliparous women (in which 80% of the insertions were copper IUDs), 63% had unscheduled bleeding at 3 months; in 40% unscheduled bleeding persisted at 1 year. 11 Forty-seven percent at both 3 months and 1 year had heavy periods, but were able to tolerate this.…”
