What is the cause of seminal obstruction?
The direct consequence of the obstruction of the spermatic duct is that the sperm produced by the testicular spermatogenic cells cannot be normally ejected through the vas deferens. If sperm cannot be ejected from the body, it must not combine with the egg to form a fertilized egg. So it can be said that the obstruction of the seminal tract may lead to male infertility. What is the cause of the obstruction of the seminal tract? Now let's invite infertility experts to introduce it in detail.
[Pathogenesis]
There are two kinds of seminal obstruction: congenital obstruction and acquired obstruction.
1. Congenital obstruction
Congenital hypoplasia of epididymis; Congenital dysgenesis or absence of vas deferens; Congenital atresia of vas deferens; Congenital ejaculatory duct obstruction can cause congenital seminal duct obstruction.
2. Obstruction of seminal tract caused by acquired factors
Acquired factors causing seminal obstruction include infection, injury and surgical ligation. There are many diseases that can cause reproductive tract obstruction, and urogenital tract infection is a common cause. Especially epididymis, vas deferens, seminal vesicles and prostate tuberculosis can cause secondary genital tract obstruction or erosion; Non-specific infection of prostate and seminal vesicle can cause edema and obstruction of ejaculatory orifice, leading to azoospermia, but once the inflammation is controlled, the edema of ejaculatory orifice will subside and normal ejaculation can be resumed. In addition, gonococcal epididymitis caused by gonococcal infection can cause infertility.
Obstruction of the reproductive tract caused by surgical injury is also common. For example, the operation of hydrocele of testis, ligation of varicocele, repair of oblique hernia, and fixation of cryptorchidism can directly damage the vas deferens or epididymis, or the blood vessels and nerves of the vas deferens, causing genital obstruction, but most of them are unilateral obstruction, rarely causing infertility; Vasectomy is an artificial obstruction of the seminal tract for contraception; Other reproductive tract obstruction diseases include seminal vesicle tumors; Seminal vesicle, prostatic cyst or calcification; Urethral stricture or atresia caused by urethral injury.
