Two brothers with bilateral vas deferens agenesis are described, one of them with a chromosome mosaicism (46,XX/47,XXY). To our knowledge, there are not any previous reports of both conditions existing simultaneously. The patients consulted us because of infertility; they have normal sexual function, normal physical examination, but typical semen analyses with azoospermia, low semen volume, low pH, and negative fructose test. It appears to us that bilateral vas deferens agenesis may be genetic in origin in some patients.
本文描述了两例患有双侧输精管缺如的兄弟，其中一人存在染色体嵌合体（46,XX/47,XXY）。据我们所知，此前尚无关于这两种情况同时存在的报道。患者因不育前来咨询；他们性功能正常，体格检查正常，但精液分析典型，表现为无精子症、精液量少、pH值低以及果糖试验阴性。在我们看来，双侧输精管缺如在某些患者中可能源于遗传。
