Dead sperm means that the sperm morphology of multiple semen is not abnormal, and the density is also in the normal range, but most sperm is dead and is one of the important factors for male infertility.The clinical manifestations of deaths are inconsistent, and some patients have no clinical symptoms; some patients may have chronic medical history, orchitis, seminal vesiculitis, etc. Some patients may have ejaculation or low sexual desire.
There are the following points for examination methods of dead essence
I. History and physical examination: Relevant factors can be obtained, such as reproductive infections, alcoholic, high temperature operations, etc.There are generally no specific signs, and patients with inflammatory diseases such as prostatitis, seminal vesiculitis, orchitis.
Second, semen examination: The result of semen examination is the basis for the diagnosis of no semen.2 semen specimens are collected after abstinence 2-3d.The amount of semen is also important (normal "1.5ml). In clinical examinations, the main reason for the small semen is incomplete. As a result, the semen collection is incomplete, and 2 specimens are required to be collected.
3. Endocrine examination: For patients with no seizure, first check the serum and T examination of the serum. If the two are normal, there is no need to do further endocrine examination.If the value of T is lower than the normal level, it should be checked by LH and prolactin.At present, some scholars believe that inhibitin B is generated by testicular support cells, which can directly reflect the sperm function of the testicular than FSH. Therefore, inhibitrin B should also be a routine test for male infertility patients.
Fourth, laboratory examination: including: semen mirror examination; routine semen examination and prostate liquid examination; semen microbiology examination; blood sperm, semen antibody antibody examination; semen biochemical analysis, etc.
V. Teste biopsy: There are two main methods for testicular biopsy: scrotum cutting biopsy and puncture biopsy.The two have their own advantages and disadvantages. The former has greater testes, but it can obtain a large amount of tissue, which is conducive to the correct pathological diagnosis; the latter is convenient to operate, and the testicular damage is small.Some researchers found that 28%of patients with testicular biopsy were inconsistent with 28%of patients on both sides of the patients.Therefore, under the circumstances of conditions, testicular biopsy should be sampled as much as possible to avoid errors.
Reminder: There are many causes caused by dead essence, such as orchitis, epididymitis, prostatitis, chronic spermal inflammation, varicocele, autoimmune, cause less essence, reproductive infection, inflammation of sexual reproductive organs, inflammation of sexual reproductive organs, inflammation of sexual reproductive organs, inflammation of sexual reproductive organs, inflammation of sexual reproductive organs, inflammation of sexual reproductive organs, inflammation of sexual reproductive organs, inflammation of sexually reproductive organs.For a long time, such as abstinence, etc., can cause death.Experts said that due to the different causes and constitutions of each person, the causes of dead essence will also be different, so it is critical to go to a regular hospital for examination!
