There are many reasons for male infertility, including mental, physiological, external factors, and so on. Among them, blocked vas deferens is one of the common causes of male infertility. So, what factors cause blocked vas deferens in men? Let's get to know together.
Experts introduce that there are several common causes of obstruction in the vas deferens pipeline:
1. Infections of the urinary and reproductive systems, such as epididymitis, prostatitis, seminal vesiculitis, or epididymal vas deferens tuberculosis, can cause obstruction of the vas deferens, with the junction between the epididymis and the vas deferens being more common.
2. Injury: such as hernia repair surgery, varicocele surgery, spermatic cord tumor surgery, etc. can damage the vas deferens; Surgery for epididymal seminal cysts and testicular hydrocele can damage the epididymis; Prostate surgery can cause obstruction of the ejaculatory duct opening; Although there is no direct injury, postoperative infection, adhesion, scar formation, etc. can cause compression and obstruction of the vas deferens pipeline.
3. Tumors, such as epididymal tumors, seminal vesicle tumors, and prostate tumors, can all cause obstruction of the vas deferens.
4. Congenital malformations: such as the absence of the head, body, and tail segments of the epididymis, partial or complete absence of the vas deferens, disconnection between the vas deferens and the epididymis, and underdeveloped epididymis, vas deferens, or seminal vesicles.
Experts point out that the treatment principle for infertility caused by obstruction of the vas deferens duct is mainly surgical treatment, such as vas deferens epididymis anastomosis, vas deferens anastomosis, artificial sperm pool surgery, urethral incision of the ejaculatory duct opening, etc., combined with anti-inflammatory treatment, improvement of spermatogenic function, improvement of semen quality, inhibition of the body's production of anti sperm antibodies, and other auxiliary treatments.
