Human spermatozoa stand apart from the gametes of virtually all other mammals in the paucity of their phenotype, the inadequacy of their function, and the sensitivity to fragmentation of their mitochondrial and nuclear genomes.

However, it appears likely that passage through the cumulus mediates or prepares the cells for AR (Tesarik et al, 1988). Frequency of AR in human spermatozoa is reported to increase significantly from control (spontaneous) levels of 14.5% plus or minus 1.5% to 24.5% plus or minus 1.9% when incubated with cumulus mass;

Human spermatozoa display unusually limited affinities in their interaction with oocytes of other species. They adhered to and, when capacitated, penetrated the vestments of the oocyte of an ape--the gibbon, Hylobates lar--both in vivo and in vitro.

Most chromosome abnormalities have their origin during meiosis, thus information on the causes of chromosome abnormalities and factors affecting their frequency are best studied in human gametes. During the past two decades there has been an explosion of information on the chromosome complement of human spermatozoa.
