"If the levels of follicle stimulating hormone and testosterone in the blood are normal, and the testicular biopsy is normal, it can be determined that the vas deferens are blocked or that there is congenital vasectomy.". Otherwise, it may be a problem with spermatogenic function. You can also do an X-ray, that is, a vasectomy and seminal vesiculography.
Be careful! Obstruction of the seminal tract can lead to infertility
This imaging technique was used in clinical practice as early as 1913, but has not been well developed due to some side effects. In the past, when performing contrast surgery, it was necessary to first cut the skin of the scrotum, and then puncture the vas deferens with an injection needle. The contrast agent was injected into the direction of the seminal vesicle before taking an X-ray film. Based on the X-ray film, it was possible to determine whether there were any problems with the seminal vesicle, prostate, ejaculatory duct, vas deferens, and ampulla of the vas deferens. This type of surgery can cause significant damage, combined with the high concentration of viscous contrast media used at the time, which can promote obstruction of the vas deferens and may cause infection, causing secondary obstruction. Later, people improved this method by using hydrophilic contrast agents, especially by puncturing the vas deferens directly through the scrotal skin without surgery, which reduced tissue damage and patient pain.
Practice has proven that this improved method improves safety and success rate. However, it is still necessary to conduct this examination in a qualified hospital. According to foreign data, infertility caused by obstruction of the seminal tract accounts for 3-10% of male infertility, with Shanghai Jiangyu Professor and others reporting 0.63%, and others reporting around 2%. Causes of obstruction of the seminal tract: ① congenital abnormality; ② Inflammation and tuberculosis; ③ Trauma; ④ Cysts or tumors; ⑤ External oppression, etc.; ⑥ Young's syndrome, often associated with bronchiectasis.
"If the obstructed site is found, and the obstructed or occluded site is not long, and surgery is possible, microsurgery can be used to anastomose it.". For example, among the more than 30000 infertile patients admitted to the University of Hamburg in the Federal Republic of Germany over the years, 1000 people belong to this type of obstructive azoospermia, or obstruction of the seminal tract. Half of the eligible patients have undergone anastomosis surgery. In other cases, symptomatic treatment can be taken for conditions such as inflammation and tuberculosis.
