Azoospermia is the medical condition of a male not having any measurable level of sperm in his semen. It is associated with very low levels of fertility.

Azoospermia has two forms:

• obstructive azoospermia, where sperm are created, but cannot be mixed with the rest of the ejaculatory fluid due to a physical obstruction, and;
• non-obstructive azoospermia, where there is a problem with spermatogenesis, as in the condition of hyperprolactinemia.

Azoospermia is a reported side effect of androgen drugs and corticosteroids because they suppress the hypothalamus release of GnRH and therefore FSH. This causes azoospermia in males and amenorrhea in females.

Azoospermia can be congenital, where it can be a manifestation of cystic fibrosis due to agenesis of the vas deferens, among other genetic conditions.
