Azoospermia :
Azoospermia is a condition in which there is absence of sperm in the male ejaculate. It may be caused due to blockage in the male reproductive tract (obstructive azoospermia) or when there is decreased sperm production by the testes (non-obstructive azoospermia). If a person suffers from azooseprmia, it does not mean that his body is not producing sperms at all. It could mean that the sperm quantity is present in such amounts that it cannot be detected in the ejaculate. Depending upon the underlying cause of azoospermia, the treatment can be provided.
