Caused by AZFa microdeletions, germ‑cell developmental gene mutations or acquired testicular injury, SCOS represents an advanced form of non‑obstructive azoospermia with major implications for fertility and genetic counselling.

Genetic defects, Y‑chromosome microdeletions, meiotic‑gene mutations and hormonal disorders lead to complete absence of sperm in the ejaculate. Understanding NOA is essential for diagnosis, genetic counselling and identifying candidates for micro‑TESE and assisted reproduction.
