In the article we present a case report of a young man who was undergoing investigation for infertility . Spermogram results showed azoo spermia . Only a complex sexological, urological and genetic examination found the cause of the couple‘s infertility, namely a structural aberration of the Y chromosome ‑ isochromosome i(Y)(p10), duplication of the short arm of the Y chromo some and deletion of the entire long arm of the Y chromosome (hence the entire AZF gene region) . This finding correlated with the clinical findings of azoospermia . Isochromosome Yp (ORPHA:98797) is a rare gonosomal aberration characterised by variable clinical manifestations including: normal healthy fertile men, men with infertility and men with ambiguous genitalia and incomplete mascu linisation . After the discovery of this chromosomal aberration, the couple decided to undergo assisted reproduction using donor sperm
