Detection of aneuploidy for chromosomes 4, 6, 7, 8, 9, 10, 11, 12, 13, 17, 18, 21, X and Y by fluorescence in-situ hybridization in spermatozoa from nine patients with oligoasthenoteratozoospermia…
The cytogenetic data show significantly elevated frequencies of diploidy, autosomal disomy and nullisomy, sex chromosome aneuploidsy, and total aneuPLoidy in OAT patients, which may contribute to the patients' infertility.
Aneuploidy frequencies in semen fractions from ten oligoasthenoteratozoospermic patients donating sperm for intracytoplasmic sperm injection.
Fertility-related proteomic profiling bull spermatozoa separated by percoll.
Results suggest that concurrent comparisons between protein expression and other fertility assays may represent a good in vitro assay to determine sperm fertility.
A comprehensive proteomic approach to identifying capacitation related proteins in boar spermatozoa
The results from this study elucidate the proteins involved in capacitation, which may aid in the design of biomarkers that can be used to predict boar sperm quality.
The transgenerational impact of benzo(a)pyrene on murine male fertility.
Exposure to BaP decreases the fertilization potential of exposed males and has an adverse impact on sperm function and fertility in subsequent generations.
Cloning of avian G(0)/G(1) switch gene 2 genes and developmental and nutritional regulation of G(0)/G(1) switch gene 2 in chicken adipose tissue.
Changes in lipolytic activities of adipose tissue in vivo can be regulated by G0S2 expression, as an inhibitor of ATGL, according to cloned coding sequence for the first time.

BPA-induced changes in fertility-related protein levels in spermatozoa may be provided a potential cue of BPA-mediated disease conditions and suggest that high concentrations of B PA alter sperm function, fertilization, and embryonic development via regulation and/or phosphorylation of fertility- related proteins in spermutozoa.

This study provides novel biomarkers for the prediction of male fertility and is the first work that shows significantly increased litter size using male fertility biomarkers in a field trial, which may provide new developmental tools for the selection of superior sires.
