Here we describe a rare case of an apparently balanced karyotype of 46, XY, t(1;22;4)(p22.3;q11.1;q31.1) in a infertile male with oligoastenoteratozoospermia (OAT). He was the second patient with complex chromosomal rearrangement (CCR) referred to our center because of infertility. We also review reports on 24 males carrying CCRs with spermatogenesis failure or a malformed child, to provide information on the reproductive outcome of male CCR carriers.

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.
