本文采用间接血凝试验对２８４倒置ＩＵＤ的妇女进行了Ｍｈ和Ｕｕ感染频率的血清学调查研究。Ｍｈ和Ｕｕ抗体阳性率分别为１５．１４％和１７．２５％，最高滴度两种抗体均为１：１２８，与对照组相比Ｐ＜０．０１，有统计学意义。而置不同类型ＩＵＤ（惰性环、活性环）之间支原体抗体阳性率无显著性差异。本文还对６６例置ＴＣｕ２００妇女支原体感染的发生情况进行了动态观察，ＩＵＤ放置后３个月内抗体阳性率及滴度明显高于放置前及放置后３～１２个月，Ｐ＜０．００１，统计学处理有非常显著的意义。以上结果提示，ＩＵＤ的使用并未提供对性传播疾病的保护作用，必须加强防治，以减少支原体感染的发生。
In this paper, indirect hemagglutination test in 284 inverted IUD women Mh and Uu infection frequency of serological investigation. The positive rates of Mh and Uu antibodies were 15.14% and 17.25%, respectively. The highest titer of the two antibodies was 1: 128, P <0.01 compared with the control group, with statistical significance. There was no significant difference in the positive rate of mycoplasma antibodies between different types of IUDs (inert rings, active rings). In this paper, 66 cases of TCu200 women with mycoplasma infection were observed dynamically, IUD placed within 3 months after the antibody positive rate and titer was significantly higher than before and 3 to 12 months after placement, P <0.001 , Statistical processing has a very significant meaning. The above results suggest that the use of IUD does not provide protection against sexually transmitted diseases, prevention and control must be strengthened to reduce the incidence of mycoplasma infection.
