先天性双侧输精管缺如(congenital bilateral absence of the vasa deferens,CBAVD)约占男性不育症的1%~2%,占无精子症的15%~20%,是梗阻性无精子症的重要原因之一~([1]),也是利用现代生育技术可以有效解决患者生育问题的疾病。国内的调查与国外文献报道基本相似。王瑞等~([2])调查了2775例男性不育症患者,从中筛查出74例CBAVD患者,占不育症的2.6%。陈斌等~([3])调查了356例无精子症患者,发现49例CBAVD患者,占无精子症的13.7%。研究发现,CBAVD与囊性纤维化病(cystic fibrosis,CF)的关系较密切~([4]),与囊性纤维化跨膜转
Congenital bilateral absence of the vas deferens (CBAVD) accounts for about 1% to 2% of male infertility, accounting for 15% to 20% of azoospermia, is an important obstructive azoospermia One of the reasons ~ ([1]), but also the use of modern reproductive technology can effectively solve the problem of patients with reproductive diseases. The domestic survey is basically similar to that reported in foreign literature. Wang Rui et al ~ ([2]) survey of 2775 cases of male infertility, screening out 74 cases of CBAVD patients, accounting for 2.6% of infertility. Chen et al ~ ([3]) investigated 356 cases of azoospermic patients and found 49 cases of CBAVD patients, accounting for 13.7% of azoospermia. The study found that CBAVD and cystic fibrosis (cystic fibrosis, CF) is closely related to ~ ([4]), and cystic fibrosis transmembrane turn
