为研究精索静脉曲张男性不育症中生殖道感染因素，对590例患精索静脉曲张（曲张组）和335例无精索静脉曲张（对照组）的男性不育患者进行了精液解脲支原体（UU）的培养研究。结果表明。UU总感染率为48．22％。曲张组中生殖道UU感染率高达55．76％，而对照组UU感染率为34．93％，两组间有高度显著性差异（P＜0．005）。曲张组精子活力低下者明显增多，而精液分析正常者明显减少。认为精索静脉曲张的存在可能使生殖道易被UU感染且不易治愈，并对精子活力具有明显影响。因此，早期治疗精索静脉曲张，消除生殖道UU感染可以防止生育能力减低和不育症的产生。
In order to study the causes of reproductive tract infections in infertile men with varicocele, 590 male infertile patients with varicocele (varicose vein) and 335 without varicocele (control group) Mycoplasma (UU) culture research. The results show. The total infection rate of UU was 48.22%. UU infection rate of genital tract was 55.76% in the varicocele group, while the infection rate of UU in the control group was 34.93%. There was a highly significant difference between the two groups (P <0.005). Qujiang Zhang sperm motility was significantly increased, while the semen analysis was significantly reduced. That the presence of varicocele may make the genitals vulnerable to UU infection and not easy to cure, and have a significant impact on sperm motility. Therefore, the early treatment of varicocele, UU infection to eliminate reproductive tract can prevent the reduction of fertility and infertility.
