🔬 New research suggests frequent ejaculation may improve male fertility by reducing DNA damage and oxidative stress in sperm over time.

📊 A large meta-analysis of 115 human studies (nearly 55,000 men) and 56 animal studies found sperm deteriorates with storage in males, regardless of age.

💡 Current WHO guidelines recommending 2-7 days of abstinence before fertility tests prioritize sperm count over quality, potentially impacting success rates.

📈 A clinical trial showed a 46% pregnancy rate with less than 48 hours of abstinence versus 36% with 2-7 days during IVF treatment.

❄️ Researchers have developed a new embryo freezing technique that significantly speeds up the process, preventing damaging ice formation within cells.

🔬 This ultrafast freezing method, tested on bovine embryos, shows promise for improving success rates in human IVF, livestock breeding, and conserving endangered species by preserving genetic diversity.

🧬 Genomic analysis revealed that the new method significantly reduced DNA damage responses in embryos compared to standard freezing techniques, allowing for better assessment of other cryopreservation impacts.
