Azoospermia mainly refers to the inability to find sperm during routine semen examination and is categorized into congenital azoospermia and obstructive azoospermia. It is difficult to get well without treatment. Congenital azoospermia is mainly caused by testicular hypoplasia, testicular atrophy, chromosomal abnormality and so on. Treatment is often ineffective and IVF may be needed if there is a need for fertility. Obstructive azoospermia is caused by a number of factors that prevent sperm from being successfully ejected. This treatment tends to be more effective. Azoospermia requires prompt medical examination and treatment to identify the cause. Do not have sex during treatment, quit smoking and drinking, and do appropriate physical exercise to strengthen the body’s immune system.
