What is idiopathic infertility

　Idiopathic male infertility includes four types: idiopathic oligospermia , idiopathic asthenozoospermia, idiopathic teratozoospermia and idiopathic azoospermia. It refers to male infertility patients except for abnormal sperm, the rest of the situation is normal, and the cause of abnormal sperm in patients is unknown, so it is called idiopathic male infertility. For example, idiopathic oligospermia means that the semen test only finds a decrease in the number of sperm, while the testicular volume, function, endocrine function, and other semen tests are normal. The reason for the decrease in sperm count is unknown. Once the reason for the decrease in sperm is found, it can no longer be called idiopathic oligospermia.
