Blockage of the vas deferens can cause sperm transport problems and can prevent the ejection of sperm. There are many causes of vas deferens blockage, including congenital abnormalities, inflammatory stenosis and tumors, etc. The appropriate treatment plan needs to be chosen according to the different causes. The main treatment for vasectomy blockage is surgery, which can solve this kind of disease. Depending on the cause and location of the obstruction, the main surgical methods are: vasectomy, vasectomy epididymal anastomosis, transurethral ejaculatory ductotomy, etc. For obstruction caused by primary diseases, such as infection, anti-infection treatment should be performed first, and for obstruction caused by mass compression, mass removal should be performed first. After these surgeries, the problem of vas deferens blockage is often solved, and the vas deferens can be opened to transport sperm, and then the patient can carry sperm in the ejaculate, so that the infertility problem can be solved. The cause of blockage is caused by infection and some side effects of the surgery, which can lead to damage to the epididymis and cause epididymal obstruction. The blockage of the vas deferens can cause infertility problems, so it is important to seek professional medical help in time to prevent the blockage of the vas deferens.
