What are the reasons for the thickening of the vas deferens?

Patient's question:

My vas deferens has become thick and hard. What are the reasons for the thickening and hardening of the vas deferens?

Doctor's answer:

Symptoms of Epididymitis
Swelling, distension, or pain in the affected scrotum, which may radiate to the abdomen or groin. Its clinical symptoms are milder than acute epididymitis, with a slower onset and a history of recurrent episodes. It is often accompanied by orchitis and epididymitis. Physical examination may reveal thickening and hardening of the epididymal segment of the vas deferens. In severe cases, the vas deferens may become adhered to surrounding tissues, with tense cremaster muscles and retraction of the scrotum and testes. Nodules of epididymitis that develop after vas deferens injury or vasectomy may spread from the center of the nodule to both ends, with the vas deferens thickening or becoming adhered. These nodules may be painful or asymptomatic.
Change unhealthy lifestyle habits, enhance physical fitness, quit smoking and drinking, and avoid spicy foods. Establish a good routine for daily life, strengthen nutrition, and engage in moderate physical exercise.
