What is the reason for the obstruction of the vas deferens? Four major causes of vas deferens blockage

If a woman wants to be pregnant, sperm participation is essential when giving birth to a child. Blockage of the vas deferens causes the sperm of men to be unable to discharge normally. In order to treat, we must know the cause of the obstruction of the vas deferens. according to

Experts said that if the unilateral vas deferens duct is blocked, it may also cause obstructive azoospermia on both sides of normal birth.

Generally speaking, there are four reasons for vas deferens occlusion:

1. Damage

For example, herniorrhaphy, spermatic cord tumor surgery, varicocele surgery, etc. may damage the vas deferens, the epididymis and testicular surgery may damage the epididymis, the prostate surgery may cause the obstruction of the ejaculatory orifice, or although there is no direct surgical injury, the formation of postoperative infection adhesion scar, etc., may cause the compression and obstruction of the vas deferens.

2. Tumor

The vas deferens are blocked by testicular tumors, seminal vesicle tumors and prostate tumors.

3. Urogenital system infection

Such as epididymitis, prostatitis, seminal vesiculitis or genital tuberculosis.

4. Congenital malformation

For example, the head, body and tail of the epididymis are absent, and the vas deferens and seminal vesicles are underdeveloped.

The clinical characteristics of the obstruction of the vas deferens are that there is no sperm in the semen examination, and the testicular development and function are normal, that is, the patient has normal spermatogenic function, but the sperm can not be discharged and passed smoothly due to the obstruction of the vas deferens, that is, the obstructive azoospermia returns to normal fertility after correct treatment.
