A rare complex chromosomal rearrangement in an oligospermic male： a case report and review of the Chinese literature

Dear Editor,
Complex chromosome rearrangements （CCRs） are structural aberrations involving at least three chromosomes with three or more chromosomal breakpoints. CCRs are very rare events in the human population. As reviewed by Pellestor et al.,1 less than 255 cases of CCRs involving three or more chromosomes have been reported. In China, approximately 136 cases of CCRs, including 40 males with reproductive problems, have been reported up to the time this review was compiled.
