Why does the vas deferens blocked?

Blockage in the vas deferens is one in the main reasons behind male infertility. However, male vas deferens most often have no obvious external symptoms, and what are causes of this? Let me expose you to the subsequent.

Insufficiency with the nature for example the absence in the head, body, and tail in the epididymis, a partial or complete absence of the vas deferens, vas deferens and epididymis usually are not connected, epididymis, vas deferens or seminal vesicle hypoplasia.

Reproductive system tumors including epididymal tumors, seminal vesicle tumors, prostate tumors causing oppression, leading to lumens, etc., might cause blockage with the vas deferens.

Reproductive system damage like varicocele, vas deferens injury after spermatic cord tumor, hernia repair, epididymal semen cyst, testicular sperm choroidal effusion surgery, can harm the epididymis; prostate surgery may cause ejaculation orifice occlusion, or There was no damage throughout the operation, nevertheless the scar was left behind as soon as the operation, so the vas deferens was compressed as well as deformed.

Bacterial virus infection Due to the invasion of some bacteria, as an example, Mycobacterium tuberculosis infects the reproductive system, which damages the seminiferous tubules and vas deferens in the epididymis, changes the composition in the seminal plasma, to cause blockage from the vas deferens.

Inflammatory infections, inflammatory infections a result of tract inflammation also can result in infection with the vas deferens, block the vas deferens, damage sperm, and cause men's infertility.
