Study of the Effect of Two New Types of IUDs,TCu380A and GyneFix on the Positive Rate of Chlamydia Trahmatis

To analyze the effect of two types of IUDs, TCu380A and GyneFix on the positive rate of Chlamydia Trahmatis (CT). Methods The TCu380A and GyneFix IUDs were compared in a randomized was for the one year and two year positive rate of Chlamydia Trahmatis (CT) and with the control respectively. Results The one year positive rate of CT antigens was 5.63% of TCu380A and two year was 4.92%; the one year positive rate of CT antigens was 4.62% and two year was 5.08% of GyneFix. There was no significant difference in the positive rate of CT antigen between the TCu380A IUD, and GyneFix IUDs groups, while there were significant differences between the TCu380A IUD, GyneFix IUD and the controls (15.18%) respectively. Conclusion Both IUDs provide highly effective protection against CT infection.

两种新型含铜IUD对宫颈沙眼衣原体阳性率影响的研究

本文报道了同期放置的TCu380A及GyneFix两种新型含铜宫内节育器在放置1年及2年时与对照组宫颈砂眼衣原体(CT)阳性率的比较。TCu380A组放置1年时阳性率为5.63％,2年时为4.92％;GyneFix组放置1年时阳性率为4.62％,2年时为5.08％,两组含铜IUD放置1年及2年时各组比较差别均无显著意义(P>0.05);对照组CT阳性率为15.18％,与上述各组比较差别均有显著意义(P<0.05)。本文结论认为含铜IUD对宫颈CT感染有抑制作用。
