Men without semen, generally need to consider the following aspects of the cause, such as loss of testicular function, testicular atrophy, body hormone level disorders, chromosomal abnormalities, bilateral vas deferens blocked, retrograde ejaculation and so on. Men without semen will not be able to give birth to the next generation, so it is a very serious problem. When this situation occurs, it is recommended to go to the hospital for relevant tests to clarify the diagnosis. If it is diagnosed as a loss of testicular function, or chromosomal abnormalities and other causes, basically there is no way to cure, it is recommended that patients can consider IVF and other assisted reproduction techniques.
