Suggestions for patients with azoospermia: The definition of azoospermia is three consecutive semen tests without sperm, requiring microscopy to find sperm need to centrifuge the semen to do sediment microscopy, so that three consecutive times still did not find sperm in order to determine the azoospermia, there are small hospitals and clinics just simply microscopic examination of the sperm can not be found to say that is the azoospermia, so the patient must be to the regular hospital to do the final diagnosis. If the diagnosis of azoospermia is confirmed, it is necessary to go to a regular hospital to find out the cause of the azoospermia, to do physical examination, chromosome examination, hormone tests, etc., to determine whether it is obstructive or non-obstructive azoospermia, if it is obstructive, it is necessary to do epididymal or testicular puncture, and after finding the sperms, it is possible to prepare to do the second generation of test tube fertilization. For non-obstructive azoospermia, there are many cases where a testicular biopsy can also be done to find sperm in the testes, which can also lead to second generation IVF. The success rate for this male cause of IVF is still very high if the female partner has normal fertility. For patients who have no sperm even in the testicular biopsy or who do not have the financial ability to do IVF, they can go to hospitals approved by the Ministry of Health to carry out donor insemination to do donor insemination, and many hospitals have this qualification nowadays. It should be noted that children born in this way have the same legal status as biological children. Alternatively, there is the option of adopting a child.
