Positioning of chromosome 15, 18, X and Y centromeres in sperm cells of fertile individuals and infertile patients with increased level of aneuploidy
TL;DR: The results obtained indicated that within the sperm nuclei of fertile individuals the centromeres of chromosomes 15, 18, X and Y were localized in a small area that may be a fragment of the chromocentre.

The analysis of meiotic segregation patterns and aneuploidy in the spermatozoa of father and son with translocation t(4;5)(p15.1;p12) and the prediction of the individual probability rate for unbalanced progeny at birth.
TL;DR: The high rate of miscarriages in this family could be explained by the genetically unbalanced karyotype and fertilization mediated by the unbalanced spermatozoa observed for both men at a frequency of more than 60%.

TL;DR: Sperm motility and lipid sperm membrane status might be the earliest and the most sensitive indicators of sperm damage with negative consequences for male factor fertility, which can be attributed to both bacteria and leukocytes action.
32
Risk evaluation of carriers with chromosome reciprocal translocation t(7;13)(q34;q13) and concomitant meiotic segregation analyzed by FISH on ejaculated spermatozoa.
TL;DR: The high rate of unbalanced gametes in comparison to the number of stillborn/early death and miscarriages detected in pedigree suggests a strong selection against unbalanced chromosomal constitutions during fetal development.
31
Interindividual differences and alterations in the topology of chromosomes in human sperm nuclei of fertile donors and carriers of reciprocal translocations
TL;DR: The study revealed that chromosomes with translocation may have shifted their intranuclear localization and that these translocations may influence the localization of other chromosomes in sperm nuclei.
