What Is This Research About?
This study is titled “Investigation of Chia Seed (Salvia hispanica L.) Extract Supplementation to Extender on Post-Thawing Ram Sperm Parameters and Genes-Related Antioxidant Capacity.”
The research examines how chia seed extracts enhance sperm viability and motility after freezing and thawing.
Who Did This Research and Where?
The study was led by Wael A. Khalil and collaborators from renowned institutions:
- Mansoura University (Egypt) – A leader in agricultural sciences.
- Tokyo University of Agriculture and Technology (Japan) – Globally respected for cutting-edge biological research.
- King Saud University (Saudi Arabia) – Known for advancing scientific research in the region.
Their international collaboration brings together expertise in animal science, antioxidant research, and reproductive biology.
Who Was Studied?
The researchers studied five Rahmani rams, evaluating 35 semen samples over a 7-week period.
The semen was frozen with extenders containing varying concentrations of methanolic chia seed extract (MCSE), and the thawed samples were analyzed for motility, vitality, and genetic markers.
What Were the Key Findings?
1. Improved Sperm Quality
- Adding 500 µg/mL of chia seed extract increased sperm motility from 30% to 43.6% after thawing.
- Vitality improved from 30.7% to 44%, and membrane integrity rose from 31.3% to 43.1%.
2. Enhanced Antioxidant Activity
- The highest dose of chia seed extract elevated antioxidant-related gene expressions, such as superoxide dismutase (720%) and catalase (1000%).
- Lipid peroxidation, measured by malondialdehyde (MDA), decreased from 12.45 nmol/mL to 6.07 nmol/mL, protecting sperm cells from damage.
3. Reduced Cell Death and Apoptosis
- Apoptotic markers like Caspase-3 decreased by 61% at higher doses of chia extract, showing reduced stress on the sperm.
Why Does This Matter?
This study reveals the remarkable antioxidant power of chia seeds, which could:
- Improve animal breeding techniques.
- Offer insights into antioxidant applications for human fertility or preservation methods.
The findings underscore the potential of natural, food-based solutions in biological science.
How Can Chia Seeds Be Useful for You?
While this research focuses on animal science, it highlights the importance of chia seeds' antioxidants. You can:
- Include them in your daily diet to support overall antioxidant levels.
- Use chia seeds in smoothies, oatmeal, or even blended drinks with apple cider vinegar.
