To report a case of simple congenital bilateral ejaculatory duct absence (EDA) complicated with seminal vesicle cyst and review the relevant literature in order to improve the diagnosis and treatment of the disease.
We retrospectively reviewed the clinical data of a case of bilateral congenital EDA complicated with seminal vesicle cyst, reviewed the relevant literature at home and abroad, and comprehensively analyzed the embryonic development, diagnosis, and treatment of congenital EDA.
The patient was a 23-year-old man, present at the clinic for infertility after married for a year. Vasography and other imaging examinations confirmed simple congenital bilateral EDA complicated with seminal vesicle cyst. Pathologic biopsy showed normal spermatogenic function of the testes.
Congenital EDA originates from embryonic developmental defect of the mesonephric duct, and it can be confirmed by vasography. Transurethral incision of the ejaculatory duct and intracytoplasmic sperm injection can be employed for the treatment of bilateral EDA.
报告1例单纯性先天性双侧射精管缺如（EDA）合并精囊囊肿的病例，并复习相关文献以提高该病的诊断和治疗水平。
回顾性分析1例双侧先天性EDA合并精囊囊肿患者的临床资料，复习国内外相关文献，综合分析先天性EDA的胚胎发育、诊断及治疗情况。
患者为23岁男性，婚后1年因不育就诊。输精管造影等影像学检查确诊为单纯性先天性双侧EDA合并精囊囊肿。病理活检显示睾丸生精功能正常。
先天性EDA起源于中肾管的胚胎发育缺陷，输精管造影可确诊。经尿道射精管切开及卵胞浆内单精子注射可用于双侧EDA的治疗。
