Congenital bilateral absence of the vasa deferentia has been found to be the cause for azoospermia in 101 patients who have been examined in our urologic practice since 1956. This represents approximately 2% of the 5112 patients seen during that time because of problems relating to infertility. Of these 101 men, 29 have had their sera tested for the presence of circulating sperm-agglutinating antibodies. The Shulman15 modification of the macroscopic gelatin sperm-agglutination test of Kibrick et al6 was used. None of these patients had had testicular biopsy. Significantly high titers (1:32 or greater) of antibodies were found in 18 (62.1%) men, low titers (1:16 or less) in five (17.2%), and no antibodies in six (20.7%).
自1956年以来，在我们泌尿外科诊治的患者中，已发现先天性双侧输精管缺如（CBAVD）是101例无精子症患者的病因。这约占同期因不育问题就诊的5112例患者的2%。在这101名男性中，29人检测了血清中循环精子凝集抗体的存在。采用了Kibrick等人6的宏观明胶精子凝集试验的Shulman15改良法。这些患者均未进行睾丸活检。18名（62.1%）男性发现抗体滴度显著升高（1:32或更高），5名（17.2%）为低滴度（1:16或更低），6名（20.7%）未发现抗体。
