用原子吸收光谱法 ( AAS)测定 1 8例精索静脉曲张 ( VC)不育患者和 1 4例正常生育的斜疝和或鞘膜积液患者外周静脉血、精索静脉血、精浆中的 Zn和 Cd的含量。结果表明 :精索静脉曲张不育患者精索静脉血和精浆中 Cd含量较对照组明显增高 ( P<0 .0 1 )、而精浆中的 Zn含量较对照组明显减低 ( P<0 .0 1 )。此外 ,其精索静脉血和精桨中 Cd/Zn比值与对照组也有显著性差异 ( P<0 .0 1 )。提示 Cd的增高可能是导致精索静脉曲张不育的原因之一。
18 cases of varicocele (VC) infertility and 14 cases of normal hernia or hydrocele patients peripheral venous blood, spermatic cord blood and seminal plasma were measured by atomic absorption spectrometry (AAS) Of Zn and Cd content. The results showed that the content of Cd in the varicocele and the seminal plasma of infertile patients with varicocele was significantly higher than that of the control group (P <0.01), while the content of Zn in the seminal plasma was significantly lower than that of the control group (P <0 .0 1). In addition, the ratio of Cd / Zn in spermatic cord and sperm also had significant difference with the control group (P <0.01). Tip Cd increased may lead to infertility varicocele one of the reasons.
