     The frequency of sperm-derived hyperhaploidy did not differ significantly between the in vivo (3.4%) and in vitro (5.9%) populations, but did between unaged (2.5%) and aged (6.8%) sperm (chi c2 = 5.74, P less than 0.01). All hyperhaploid zygotes had a complement of n + 1 chromosomes, except the 14-d in vitro group, where complements of n + 2 and n + 3 chromosomes were seen.

   • 2000, Bernardini L; Gianaroli L; Fortini D; Conte N; Magli C, “Frequency of hyper-, hypohaploidy and diploidy in ejaculate, epididymal and testicular germ cells of infertile patients”, in Human Reproduction, volume 15, number 10, DOI:10.1093/humrep/15.10.2165, PMID 11006193, pages 2165-2172:

     Additional work is required to confirm the real frequency of hyperhaploidy in the heterogeneous population of germ cells retrieved at testicular level.
