Venture pipe blockage is a major incentive for male infertility. Once the vollarization pipe is blocked, the sperm cannot be circulated smoothly, which eventually leads to infertility. So what are the causes of the transparent tube blockage?
Causes of blocked tubal pipes
1) Infection of the urogenital system: such as epididymitis, seminal vesiculitis, or tuberculosis tuberculosis, etc., cause obstruction of vasters of vasters, and is more common in connection with epididymia and vasters.
2) Damage: such as hernia repair, spermatic veins, and spermatogenic tumor surgery and other injured pipes; epididymal sperm cysts, testicular hydrocellic effusion surgery can hurt the epididymia;Although there is no direct damage, the formation of adhesion scars after surgery can cause pressure and obstruction of the vasters.
3) Tumors: such as epididymal tumors, seminal tumors, prostate tumors, etc., can cause transmitting tubular obstruction.
4) Congenital malformations: such as epididymal head, body, and tail section, such as a section or completely missing, vastered pipes are not connected to epididymia, an epididymal, vasal tubes or seminal vesicles are inaccurate.
What inspections need to be done if the vas deferens are blocked
1. Ultrasonic examination
Ultrasonic examination is a diagnostic effect on the lack of natural vasters, the lack of seminal vesicles, and the prostate dysplasia, as well as the diagnostic effect of ejaculation tube cysts and epididymal cysts, and it is simply no damage. It is a non -invasive diagnosis and examination method.Through rectal ultrasound detection, we can clearly understand the shape and size of the prostate and seminal vesicles, as well as internal echoes and envelope conditions.Scrotum ultrasound examination can detect testicles, epididymia and vascular vasters, as well as spermatic lesions.
2. Reproductive hormone measurement
Serum FSH and LH and PRL levels are within normal range.Therefore, the detection of reproductive hormones does not seem to be necessary to diagnose the diagnosis of seizure obstructive male infertility, but it can be provided to confirm the diagnosis of sperm -mobo.
3. Voltic tube angiography
Voltage tubal angiography is a reliable examination method that is diagnosed with the seizure of the seizure, and the blocking site and range.
4. Semen examination
Contains semen and sperm physiological biochemical examination.Use semen to check whether the function and sperm of the accessory glands are unobstructed.
