Azoospermia is when we don’t have a single sperm in ejaculate. This can be mainly due to two different reasons. Either because there are an obstruction and the testicles can produce sperm, but these sperm do not reach ejaculate. For example, in the vasa deferentia agenesia, which is quite a common situation in the Mediterranean area, or it could be because the testicles are not able to produce a sufficient amount of sperm.

The first one is called obstructive azoospermia, the second one is called secretory azoospermia, and the prognosis tends to be worse.
