Sperm is produced by the seminiferous tubules of the testis, and then sent out of the body through the epididymis, vas deferens, ejaculatory ducts, and urethra. "As long as there is a blockage in any part of the sperm 'path', sperm movement and excretion are impaired, which can lead to male infertility.". "Who caused the obstruction of the seminal tract?"?
Who caused the obstruction of the seminal tract?
1. Congenital obstruction Congenital epididymis hypoplasia; Congenital malformation or absence of the vas deferens; Congenital atresia of the vas deferens; Congenital ejaculatory duct obstruction can cause congenital obstruction of the seminal tract.
"Acquired factors that cause obstruction of the seminal tract include infection, injury, and surgical ligation.". There are many diseases that can cause reproductive tract obstruction, and urogenital tract infection is a common cause. In particular, tuberculosis of the epididymis, vas deferens, seminal vesicles, and prostate can cause secondary reproductive tract obstruction or erosion; Non specific infections of the prostate and seminal vesicles can cause edema and obstruction of the ejaculatory orifice, leading to azoospermia. However, once the inflammation is controlled, the ejaculatory orifice edema subsides, and normal ejaculation can be resumed. In addition, gonorrheal epididymitis caused by gonococcal infection can even cause infertility.
Obstruction of the reproductive tract caused by surgical injuries is also common. For example, surgery for hydrocele of the testis, ligation of varicocele, repair of oblique hernia, and fixation of cryptorchidism can directly damage the vas deferens or epididymis, or damage the blood vessels and nerves of the vas deferens, causing genital tract 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, prostate cyst or calcification; Urethral stenosis or atresia caused by urethral injury.
How to treat seminal obstruction?
1. Anti infection: Ejaculatory orifice edema caused by genital tract infection generally does not require surgery. Through anti infection and physical therapy to control inflammation, the edema subsides, and the genital tract can be restored to patency.
2. Vasostomy: If the obstruction is in the vas deferens, it is feasible to resect the obstruction and perform end-to-end vasectomy.
3. Vaso epididymostomy: If the lesion is in the tail of the epididymis, vasectomy epididymostomy is feasible.
4. Tumor excision: Surgical removal of spermatic cord, seminal vesicle, prostate tumor or cyst is feasible.
5. Treatment of urethral stricture or atresia caused by urethral trauma by urethrotomy or urethroplasty.
Artificial seminal vesicles: For those with underdeveloped or absent vas deferens, artificial seminal vesicles can be used to collect sperm in the epididymis and then undergo artificial fertilization to solve fertility problems.
