Journal ArticleDOI
Distribution of aneuploidy in human gametes: comparison between human sperm and oocytes.
TL;DR: All chromosomes are susceptible to nondisjunction but that chromosome 21 is particularly prone to aneuploidy in both human sperm and oocytes, and it is demonstrated that sex chromosome aneuPLoidy is common in human sperm but not in human oocytes.
Journal Article
The relationship between paternal age, sex ratios, and aneuploidy frequencies in human sperm, as assessed by multicolor FISH
TL;DR: The results do not support a correlation between paternal age and sex ratio or diploidy, and the frequencies of X- and Y-chromosome-bearing sperm, diploidsy and disomy for chromosomes 1, 12, X, and Y in sperm from 10 normal men aged 21-52 years.
Journal ArticleDOI
Is there a relationship between sperm chromosome abnormalities and sperm morphology
TL;DR: There may be an association between sperm morphology and aneuploidy in infertile men with specific abnormalities, according to a review of techniques for obtaining information on the chromosome complements of spermatozoa.
Journal ArticleDOI
Human male recombination maps for individual chromosomes.
F. Sun,F. Sun,Maria Oliver-Bonet,Maria Oliver-Bonet,Thomas Liehr,Heike Starke,Evelyn Ko,Alfred Rademaker,J. Navarro,J. Benet,Renée H. Martin,Renée H. Martin +11 more
TL;DR: The first (to the authors' knowledge) recombination maps for every autosome in the human male obtained by new immunofluorescence techniques followed by centromere-specific multicolor fluorescence in situ hybridization in human spermatocytes are presented.
Journal ArticleDOI
Cigarette smoking and aneuploidy in human sperm
Qinghua Shi,Qinghua Shi,Evelyn Ko,Leona Barclay,Tina Hoang,Alfred Rademaker,Renée H. Martin,Renée H. Martin +7 more
TL;DR: It is concluded that cigarette smoking may increase the risk of aneuploidy only for certain chromosomes and that men may have different susceptibilities to aneuPLoidy in germ cells induced by cigarette smoking.
