To estimate the presence of latent Chlamydia Trachomatis (C.T.) infections, we have carried out a study on a selected group of couples affected by unexplained sterility and infertility. We examined 193 women and, as control group 210 healthy fertile women. For both groups the main risk factors that could explain the infection epidemiology have been analyzed. The parameters considered are age of first intercourse, number of partners, social-economic conditions and number of voluntary abortions. Amongst all the causal agents of sexually transmitted diseases (STD), C.T. was most common, with an incidence of about 12 per cent in the study group versus the 5.7 per cent of the control group (chi 2 = 4.12).
为了评估沙眼衣原体（C.T.）潜伏感染的存在情况，我们对一组受不明原因不孕不育影响的夫妇进行了一项研究。我们检查了193名女性，并以210名健康的可育女性作为对照组。针对两组人群，我们分析了可能解释感染流行病学的主要风险因素。所考虑的参数包括首次性交年龄、性伴侣数量、社会经济状况和人工流产次数。在所有性传播疾病（STD）的病原体中，沙眼衣原体最为常见，研究组的发病率约为12%，而对照组为5.7%（卡方检验=4.12）。
