精索静脉曲张是男性继发性不育的常见原因。调查资料表明:精索静脉曲张在青春发育期男性中的发病率为15％;在男性不育患者中的发病率高达40％(21～41％),故世界卫生组织在男性不育症研究中把精索静脉曲张不育症列为首位。但是精索静脉曲张所致不育的机理至今尚未完全阐明。目前认为精索静脉曲张导致不育和以下几种因素有关:1.睾丸局部温度升高,影响精子的发生;2.内分泌激素水平的改变,睾酮的生物合成受到影响,干扰了精子的生成;3.睾丸静脉血液淤滞,睾丸组织血液循环受影响,组织内缺氧和二氧化碳蓄积,组织出现营养障碍;4.血液逆流,肾静脉内的代谢产物和部分激素如类固醇类激素、前列腺素逆流到精索静脉,影响精子生成;5.附睾功能受损,精子成熟出现障碍。近年来,随着基础医学研究的进展,特别是免疫学的飞速发展,新的免疫学检验
Varicocele is a common cause of male infertility. Survey data show that: the incidence of varicocele in adolescent male development was 15%; incidence of male infertility as high as 40% (21-41%), so the World Health Organization in male infertility research In the varicocele as a priority. However, the mechanism of infertility caused by varicocele has not yet been fully elucidated. Now that varicocele lead to infertility and the following factors: 1. Testicular local temperature, affecting the occurrence of spermatogenesis; 2. Endocrine hormone levels, testosterone biosynthesis are affected, interfere with the formation of sperm; 3.Testicular venous blood stasis, testicular tissue affected by blood circulation, tissue hypoxia and carbon dioxide accumulation, tissue nutrition disorders; 4. Blood reflux, renal vein metabolites and some hormones such as steroid hormones, prostaglandin reflux Varicocele, affecting sperm production; 5 epididymis dysfunction, sperm maturation obstacles. In recent years, with the progress of basic medical research, especially the rapid development of immunology, a new immunological test
