Scientist say that, exercise promotes healthy hormone level that improves environment inside testes.

Sperm quality has generally fallen over the past 50 years.

Men hoping to have children in the future would do well to get to the gym, after a study found exercise could help their sperms 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 hormones 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.

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 subject display better semen values.
