Difference between types of azoospermia

Testicular biopsy has both diagnostic and therapeutic purposes. This test is performed when no sperm are found in the man's ejaculate.

In this way, testicular biopsy makes it possible to distinguish between two types of pathologies in men:

• Pathology of obstructive type: when the seminal ducts that allow the semen to exit are blocked. This type of pathology is known as obstructive azoospermia.
• Pathology of secretory type: there is no sperm production or the sperm do not finish their maturation process, which is called secretory azoospermia.
