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.congenital azoospermia, where azoospermia is a manifestation of
cystic fibrosis due to
agenesis of vas defrens. 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.
