Simple workflow for genome and methylation analyses of ejaculated bovine spermatozoa with low sperm input.

ABSTRACT: We developed a simplified workflow of gDNA extraction from ejaculated bovine sperm using a low total number of sperm and a short time frame that yields high-quality DNA suitable for downstream methylation and genome analyses. These techniques have broad implications in human biomedical sciences and agriculture, including clinical diagnoses of infertility, the identification of single-nucleotide polymorphisms and aberrant methylation patterns that can impact fertility, lower embryo development and contribute to heritable disease. The methods described here provide a reliable, simplistic approach for analyzing both the genomic and epigenomic status of whole sperm ejaculates that can be adapted for laboratory diagnostics, clinical reproductive practice and basic research.
