Azoospermia is a seminal alteration characterized by the absence of spermatozoa in the ejaculate. There are two types of azoospermia.
First, obstructive azoospermia is when there is no sperm expulsion in the ejaculate due to the presence of obstruction in the seminal ducts. However, men with obstructive azoospermia do produce spermatozoa, although they are not able to expel them to the exterior. This is why obstructive azoospermia is less severe than secretory azoospermia.
Secondly, secretory or non-obstructive azoospermia is caused by alterations in spermatogenesis, that is, in the production of spermatozoa. This type of azoospermia is the most frequent.
