Men who are hoping to have children in the future would do well to get to the gym, after a study found exercise could help their sperm to swim faster.
Researchers found men who worked out more had faster swimming sperm that was better formed, compared to their sedentary peers.
They suggest that exercise promotes healthy hormone levels that create a better environment in the testes for sperm production.
The findings, from the University of Cordoba in Spain, are important because semen quality has dropped overall in the last 50 years.
Many factors have been blamed including drinking, smoking, and the rising levels of obesity.
The team assessed whether there was any difference in the hormonal levels and semen quality of men who were physically active compared to those who weren't.
They looked at factors including sperm count and mobility and analysed hormones including testosterone, cortisol and the follicle-stimulating hormone.
The results concluded physically active subjects display better semen values.
