MetabolomicsSericin Enhances Cryopreserved Sperm Quality in Chengde Hornless Black Goats by increasing Glutamine metabolism

Cryopreservation of Chengde polled goat semen plays a critical role in conserving genetic resources, enhancing the utilization efficiency of superior breeding rams, and advancing artificial insemination techniques. However, spermatozoa are vulnerable to oxidative stress during the freezing proces...

MetabolomicsChronic exposure to tire rubber-derived contaminant 6PPD-quinone impairs sperm quality and induces the damage of reproductive capacity in male mice

The study investigates the effects of 6PPDQ on male fertility in adult mice. The findings of this study are essential as the effects of low-dose environmental factors of 6PPDQ on adult male infertility are unclear, with the increasing in male infertility. The results suggest that 6PPDQ adversely ...

MetabolomicsIntegrative analysis of blood biochemistry and sperm metabolome profiles reveals metabolic determinants of cryotolerance in Bali bulls under standardized nutritional conditions

Enhancing the nation's beef supply and guaranteeing long-term food security requires increasing the effectiveness of artificial insemination (AI) in Bali cattle (Bos javanicus). Cryotolerance, or post-thaw variability in semen quality, limits AI results and probably reflects systemic and cellular...

MetabolomicsA new perspective on semen quality of aged male: The characteristics of metabolomics and proteomics

BACKGROUND: Semen quality is negatively correlated with male age and is mainly quantified by a routine semen analysis, which is descriptive and inconclusive. Sperm proteins or semen metabolites are used as the intermediate or end-products, reflecting changes in semen quality, an...

MetabolomicsTEX44 CPT1B Axis Regulates Mitochondrial Sheath Assembly and Fatty Acid Oxidation in Sperm
Mitochondrial fatty acid β-oxidation (FAO) is essential for energy production and cellular homeostasis, yet its specific role in sperm function has remained unclear. Through whole-exome sequencing of 673 patients with asthenozoospermia, we identified biallelic TEX44 variants in six individuals, all ...

TranscriptomicsrRNA cleavage ensures translational cessation in the mature sperm
We report how unique RNA seq profiles of ribosomal RNA (18S, 28S) present in sperm indicate specific cleavage sites. Additionally, these sequencing results reveal how overall character of RNA (GC content) can significantly affect overall distribution of mapped reads. Examination of rRNA population ...

TranscriptomicsStallion sperm transcriptome as revealed by microarray analysis and RNA sequencing
Purpose: In order to understand the functional significance of sperm transcriptome in stallion fertility, the aim of this study was to generate a detailed body of knowledge about the sperm RNA profile that defines a normal fertile stallion. Methods: The 50 bp single-end ABI SOLiD raw reads were dire...

TranscriptomicsDifferential RNAs in the sperm cells of asthenozoospermic patients
Alterations in the presence of sperm RNAs have been identified using microarrays in teratozoospermic (abnormal morphology) or other types of infertile patients. However, so far no studies had been reported on the sperm RNA content using microarrays in asthenozoospermic patients (low motility). We st...
