In clinical practice, the judgment of sperm malformation is that in normal form, the number of malformed sperm in the patient’s semen is higher than 96% of the total, that is, the normal sperm content should be lower than 4% of the total to confirm the diagnosis of malformed spermatozoa. Causes include environmental factors such as radiation, pollution, frequent exposure to chemical materials, disease factors such as orchitis and varicocele, and poor lifestyle habits such as long-term alcohol consumption, smoking, and staying up late. In addition, if you are in a high temperature environment for a long time, such as sauna, hot bath, etc., can lead to an increase in sperm malformation rate. At this time, you need to go to the hospital in time, and you can obtain normal sperm by screening method.
