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.
We report on a phenotypically normal man with infertility, whose 47,XY,+mar karyotype was studied by spectral karyotyping (SKY) and fluorescence in situ hybridization (FISH) using a chromosome-15-specific probe (LSI SNRPN). By these techniques, the marker chromosome was identified as a small inv dup (15). Possible causes for male infertility in this case are discussed.
