Key Findings
- The study from the University of South Bohemia examined the effects of short-term sperm storage on DNA methylation in common carp embryos
- Short-term sperm storage reduced sperm motility, viability, and DNA integrity but did not change global DNA methylation levels in sperm and embryos
- Despite no global changes, specific DNA methylation alterations were found in key genes, potentially affecting embryonic development
