Non-obstructive Azoospermia is when mature sperm are not found in the semen because of a problem with their production. This can occur at different stages of the male reproductive cycle and in some cases a form of surgical sperm retrieval or SSR can be used to retrieve mature and viable sperm.
Causes of non-obstructive azoospermia can include radiation, certain types of medications, infections or hormonal imbalances. Micro-TESE would be advised in cases of non-obstructive azoospermia followed by In-vitro fertilisation (IVF) with Intra-cytoplasmic sperm injection (ICSI).
