Complex Chromosomal Rearrangements (CCRs) are rare structural abnormalities that are usually associated with infertility or subfertility in male carriers. We described clinical and chromosomal features of a non-obstructive azoospermic male that has been referred for infertility. Cytogenetic analysis showed three chromosomes, i.e. 3, 8 and 16, which have been involved and caused spermatogenesis failure.
