Chromosome aneuploidy in the spermatozoa of two men with globozoospermia.
The objective of this study was to determine the aneuploidy level in spermatozoa in two men with globozoospermia. Sperm nuclei were analysed by fluorescence in-situ hybridization (FISH) in two infertile males with globozoospermia. Dual FISH for chromosomes 7 and 9, 13 and 21, and triple FISH for chromosomes X, Y, and 18 was performed. The main outcome measured was meiotic segregation difference...
متن کاملAnalysis of chromatin integrity and DNA damage of buffalo spermatozoa
This study was conducted to determine chromatin integrity and DNA damage by DNA electrophoresis and comet assays of buffalo fresh and frozen semen. Semen samples were collected from four buffalo bulls and evaluated after freezing for semen motility, viability, sperm abnormalities, chromatin integrity and DNA damage. A significant variation was found in semen parameters after thawing. Highly sig...
متن کاملAneuploidy and early human embryo development.
Human embryo development occurs through a process that encompasses reprogramming, sequential cleavage divisions and mitotic chromosome segregation and embryonic genome activation. Chromosomal abnormalities may arise during germ cell and/or pre-implantation embryo development, and are a major cause of spontaneous miscarriage or birth defects. Nonetheless, model systems suitable for the study of ...
متن کاملObscure effect of aneuploidy on embryo morphology.
In this issue, Fragouli et al. report the results obtainedbyexamining a total of 1213 embryos by combining comprehensive chromosome analysis with a systematic assessment of embryo morphology. At the cleavage stage, chromosome abnormalities were common even amongst embryos assigned the best morphological scores, indicating that aneuploidy has little effect on microscopic appearance during the fi...
متن کاملImpact of ovarian stimulation with gonadotrophins on embryo aneuploidy.
Sir, We have read the article published in your journal by Taylor et al. (2014) with much interest. In this review the authors properly summarize the mechanisms, origins and incidence of chromosomal mosaicism in humans. The review is rigorous, exhaustive and very well-documented, and therefore we congratulate the authors for their work. Nevertheless, we find that some relevant information about...
