Constitutional complex chromosomal rearrangements in azoospermic men-case report and literature review

Complex chromosomal rearrangements are very rare and may lead to spermatogenic defect. We report on an infertile man with complex constitutional chromosomal rearrangements. The chromosomal breakpoints were located at 9p22, 13q22, and 21p11. This is the seventh case, to our knowledge, of complex chromosome rearrangements in a man presenting with a spermatogenic defect. The spermatogenic defect may be ascribed to disruption of sterile genes during chromosomal breakage or abnormal meiotic segregation of the rearranged chromosomes.
