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.

SYCP2 is a meiosis‑specific protein that forms the lateral elements of the synaptonemal complex. Its interaction with SYCP3 is essential for chromosome pairing, recombination, and fertility.

SYCP1 is a meiosis‑specific protein that forms the transverse filaments of the synaptonemal complex. Its correct assembly is essential for homologous chromosome pairing, recombination, and fertility.

SYCP3 is a meiosis‑specific protein essential for chromosomal synapsis and the formation of the synaptonemal complex. Mutations in SYCP3 are linked to meiotic arrest, infertility, and genomic instability.
