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.

Its interaction with SYCP3 is essential for chromosome pairing, recombination, and fertility.

Its disruption leads to meiotic arrest, aneuploidy, and reproductive disorders.
