Review of the past and current studies assessing sperm quality based on HOST class. This figure summarizes the results of the present study as well as of others on the respective quality of the HOST classes, based on the following parameters: DNA fragmentation, DNA decondensation, phosphatidyl-serine externalization, aneuploidy, chromosomal segregation in rearrangement carriers, inter-telomeric distance, and chromosomal territory area. For each parameter and study, the results were normalized: 100% means that the HOST class showed the highest score for a given parameter, and 0% means it showed the lowest score. We highlight the relatively higher quality of spermatozoa belonging to the B and B+ HOST classes, and the relatively poorer quality of those belonging to the A, G, and possibly C, D/E, and F classes
