A new study from the University of Oxford has revealed a surprising link between ejaculation frequency and sperm health. Researchers analysed 115 studies involving nearly 55,000 men.
The study found that sperm stored for longer periods tends to deteriorate over time. While short-term abstinence can increase sperm count, quality appears more important.
Longer gaps between ejaculation were linked to reduced sperm motility and viability, along with increased DNA damage.
Scientists believe oxidative stress—similar to biological “rust”—and energy depletion are the main causes. Sperm cells lose functionality when stored too long.
These findings challenge the common advice that men should abstain for several days to improve fertility. More frequent ejaculation may “refresh” sperm and remove older, damaged cells.
Current medical guidelines still recommend abstaining for two to seven days before providing a sperm sample for testing or IVF. However, the new research suggests shorter abstinence may sometimes improve quality.
The study comes as interest in male fertility grows, with scientists exploring factors that influence reproductive health.
Experts advise consulting a medical professional for personal concerns regarding fertility.
