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 کاملSpermatozoa protein alterations in infertile men with bilateral varicocele
Among infertile men, a diagnosis of unilateral varicocele is made in 90% of varicocele cases and bilateral in the remaining varicocele cases. However, there are reports of under-diagnosis of bilateral varicocele among infertile men and that its prevalence is greater than 10%. In this prospective study, we aimed to examine the differentially expressed proteins (DEP) extracted from spermatozoa ce...
متن کاملP-11: Differential Expression of mRNA Aromatase in Ejaculated Spermatozoa from Infertile Men in Relation to either Asthenozoospermia or Teratozoospermia
Background Estrogens biosynthesis in ejaculated spermatozoa is an autonomous process that may influence sperm functions. The purpose of this study was to evaluate the relationship between the expression of aromatase, sperm quality and seminal neutral α–glucosidase marker in semen of Tunisian infertile men. MaterialsAndMethods Fifty seven men were investigated: they were composed of two groups: ...
متن کاملAbnormal meiotic recombination in infertile men and its association with sperm aneuploidy.
Defects in early meiotic events are thought to play a critical role in male infertility; however, little is known regarding the relationship between early meiotic events and the chromosomal constitution of human sperm. Thus, we analyzed testicular tissue from 26 men (9 fertile and 17 infertile men), using immunofluorescent techniques to examine meiotic chromosomes, and fluorescent in situ hybri...
متن کاملMajor protein alterations in spermatozoa from infertile men with unilateral varicocele
BACKGROUND The etiology of varicocele, a common cause of male factor infertility, remains unclear. Proteomic changes responsible for the underlying pathology of unilateral varicocele have not been evaluated. The objective of this prospective study was to employ proteomic techniques and bioinformatic tools to identify and analyze proteins of interest in infertile men with unilateral varicocele. ...
