Non-obstructive azoospermia

Sperm production itself is severely impaired.

Male fertility

In non-obstructive azoospermia FSH is often raised and testes may be small. Small pockets of sperm production can still exist, and microTESE finds usable sperm in roughly half of cases in experienced hands. Genetic testing is recommended before surgery.

Also known as: NOA, testicular failure
