That could be either a azoospermia or necrospermia. This condition can be caused by acquired condition or be congenital. I think I need to know more details about your condition so that I can offer more appropriate suggestions. Please answer following questions:
What do you do for living?
Did you previously have any STD?
Did you have mumps in childhood?
Do you have any symptoms like pain or problem with uinating?
Are you presently on any medication(not for this condition)?
Do you smoke and drink alcohol? If you do, how often?
Are there any other tests that you've done except for semen analysis?
Please reply me via email at wuhandrlee@hotmail.com, and we can have further discussion on this.
