Patient's question:
How can the vas deferens become blocked? What are the symptoms of a blocked vas deferens in men?Doctor's answer:
The symptoms of vas deferens obstruction are primarily the absence of sperm in the semen or a significantly reduced sperm count; normal or mildly elevated levels of blood FSH; normal or slightly enlarged testicular morphology with relatively normal texture; and abnormal palpation of the epididymis or vas deferens. The causes of vas deferens obstruction are complex and diverse, such as many common urogenital infections like epididymitis, prostatitis, and seminal vesiculitis; congenital malformations of the vas deferens; tumor-related conditions; and obstruction caused by surgical trauma. Early treatment is recommended.
