A study led by the University of Oxford has found that frequent ejaculation can significantly increase sperm count. The study examined data from over 54,000 men and dozens of animal species, and found that longer periods of abstinence are linked to increased DNA damage, higher oxidative stress, and reduced sperm motility. The researchers suggest that old sperm is worse than new sperm, and if you want better quality, ejaculating more regularly. The research team also noted that sperm cells are fragile and quickly burn through energy, leaving them vulnerable to damage from reactive oxygen molecules. Despite these findings, the research team described the effects as modest and not catastrophic. However, fresh sperm collected within 48 hours of their creation may improve outcomes in clinical settings like IVF.
