The scientific name of azoospermia is azoospermia. Patients with azoospermia usually have no conscious symptoms, and most of them seek medical treatment for infertility, and some of them are accompanied by other complications. A typical symptom of azoospermia is that the wife has not taken contraceptive measures after marriage, and the wife has not been pregnant for more than one year after marriage, and often goes to the hospital for a semen examination to find no sperms because of infertility after marriage. Some patients may have localized pain, redness, swelling, fever, etc., or may have difficulty in urination or ejaculation. Long-term azoospermia can cause psychological abnormalities, such as anxiety, depression and other symptoms. Azoospermia is a condition in which semen is obtained by extracorporeal emission after 3-7 days of abstinence, and no spermatozoa are detected on more than 3 consecutive laboratory tests, as well as on centrifugal microscopic examination of semen. It may be due to germ cell dysplasia, bilateral cryptorchidism, endocrine disorders, trauma, and environmental factors. In addition, patients with azoospermia are advised to go to the hospital in time to avoid delay.
