In the clinic, when the examination revealed no sperm, it should re-review, in order to determine if there are inspection errors.If the sperm were not found in patients with multiple inspections sperm, which can be diagnosed azoospermia. It should be explained that the patient's semen with normal sperm is no different, the process of their sexual life, sexual pleasure as well as the ejaculatory process is no exception, but there is no sperm in semen.
    Once the disease is no sperm, but also further examination, but not on instructions from the loss of fertility. Clinically, azoospermia can be divided into two categories, one is because the testicular spermatogenic dysfunction itself caused no production is equal to the product processing plants, so there is no any product supply; the other is testis spermatogenic function normal, can produce qualified products, but because of the vas deferens obstruction, so that testicular sperm generated in vitro can not be discharged, this is called obstructive azoospermia.
    Testicular spermatogenic dysfunction caused by common causes are: no testosterone disease. Testicular sperm production the only place, there is no testicles, sperm production does not arise. In the absence of the testicles, thus there is no therapeutic value, there is no need to take any drugs; bilateral cryptorchidism. This situation is not that this should be to the testicles scrotum, remain in the abdominal cavity due to temperature is much higher than in the scrotum, sperm there is no way to generate, can occur without sperm. This situation can be surgical treatment, should be explained that the earlier the treatment time, the effect the better; congenital hypoplastic seminiferous tubules (also known as Kline-Felter syndrome), which is also a developmental reasons , although the location of the testis there is no problem, but the sperm production of the same problems. The disease, if found in time, the condition is not very serious, there is hope of treatment; after mumps orchitis caused by viral, as well as gonorrhea, syphilis, testicular tuberculosis. This situation is being acquired testicular injury, a violation of its Health and sperm function, there will be no sperm or very few sperm.In that case, the key is prevention, if the factors found to be infected, it should be timely and wipe out the cause, prevention of diseases increased; genital injuries. External damage or injury caused testicular torsion, spermatic cord torsion, or for hernia repair surgery, prostate surgery, trauma, etc. also affect testicular function, leading to sperm production bottlenecks. This is mainly to take effective measures to prevent and promptly; radiation exposure. Sperm is very fragile, and if a strong electromagnetic waves, radiation front, he will face extinction.The cause is only to take preventive measures; testis local temperature.  Often, a long laundry water, bath, sauna, or other factors caused by testicular temperature, can affect sperm production, but such cases are mostly less sperm, the sperm and so much death. In real life, should avoid all the factors that enable increased testicular temperature; edible cottonseed oil. The oil contains a component called gossypol, which components can inhibit sperm production, so people used to male contraception, fertility of men who intend to eat more, sperm occurs decrease or even disappear. If you eat too much cottonseed oil, is difficult to return to normal after the cessation; varicocele. This situation will seriously affect the testicular blood supply, thereby affecting testicular spermatogenic function, also occurs a significant reduction in sperm or even disappear.Timely surgery or drug therapy (mild persons) is expected to most of the patients to return to reproductive function;
Caused by obstructive azoospermia main reasons: congenital bilateral absence of vas deferens; reproductive tract damage, such as urethral injury is not repaired, spermatic cord injury in operation and did not promptly detect and repair, etc.; reproductive system inflammation such as epididymitis, epididymal tuberculosis, prostatitis, Vesiculitis so can cause the vas deferens obstruction; seminal vesicle cyst and other benign tumors, such as seminal vesicle.
