Metabolomic approaches allow the study of downstream gene expression events since
metabolites are considered as the products of cell signaling pathways. For this reason, many …

The last decades of research have revealed that many other factors besides gamete
genomes are able to determine the reproductive outcomes. Indeed, paternal factors have …

The preservation of semen is pivotal in animal reproduction to ensure successful fertilization
and genetic improvement of livestock and poultry. However, investigating the underlying …

Whether basal metabolic activity in sperm has any influence on their fertilising capacity has
not been explored. Using the pig as a model, the present study investigated the relationship …

Sperm survival and activity depend on the provision of energy and nutrients from seminal
plasma (SP). This study aimed to investigate the variations of metabolites within SP before …

Background Metabolomic approaches, which include the study of low molecular weight
molecules, are an emerging-omics technology useful for identification of biomarkers. In this …

Bull fertility is crucial for efficient, profitable, and sustainable agriculture of cattle. Despite the
fact that the uses of sperm from low fertility bulls cause millions of dollars economic losses …

Holding at room temperature is the first step in most boar semen cryopreservation protocols.
It is well accepted that a holding time (HT) of 24 h increases sperm cryotolerance. However …

In pigs, ejaculate is expelled in fractions, mainly the sperm-rich fraction (SRF) and the post-
SRF (PSRF), which differ in both sperm content and origin. In addition, intra-ejaculate …

Previous research revealed that several seminal plasma (SP) metabolites are related to
sperm functionality, fertility, and preservation. While it is understood that variations between …
