Sertoli Cell‑Only Syndrome
Sertoli‑cell‑only syndrome is a severe testicular disorder in which seminiferous tubules contain only Sertoli cells and no germ cells. 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.
Non-Obstructive Azoospermia
Non‑obstructive azoospermia is a severe form of male infertility caused by failure of spermatogenesis. 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.
