The present study was aimed to investigate differences in molecular signatures in oocytes
derived from Holstein-Friesian heifers with different genetic merit for fertility, euthanized …

Background Without intensive selection, the majority of bovine oocytes submitted to in vitro
embryo production (IVP) fail to develop to the blastocyst stage. This is attributed partly to …

Associations between expression of some proteins in spermatozoa and fertility have been
sought in recent years to identify the male fertility markers. Since the incidence of sub-fertility …

In cattle, early embryonic failure plays a major role in the limitation of reproductive
performance and is influenced by genetic effects. Suboptimal oocyte quality, including an …

Basic understanding of molecular features of ovaries and comparison of biological events in
ovaries of different beef cattle breeds with indigenous potential has been indicated to …

Poor semen profile reflected by suboptimum fertility statistics is a concern in bulls reared for
breeding purpose. A critical review of research on candidate genes and proteins associated …

In the study presented here we identified transcriptomic markers for fertility in the cargo of
pig ejaculated spermatozoa using porcine-specific micro-arrays (GeneChip® miRNA 4.0 …

Sub-fertility is a major problem in crossbred bulls leading to disintegration of breeding
systems and huge economic loss. Identification of some potential biomarkers to determine …

The reason for poor semen quality among the breeding bulls is not well understood. In the
present study, we performed high‐throughput RNAseq analysis of spermatozoa to identify …
