Discovering the relationship between sperm quality and longevity in men

A large 50-year study of over 78,000 men has discovered a key factor in longer life expectancy in men.

New research recently published in the scientific journal Human Reproduction has discovered a link between sperm quality and longevity in men, according to the medical news site News Medical.

Scientists from Copenhagen University Hospital (Denmark) assessed the "sperm" quality of 78,284 men from samples taken between 1965 and 2015 at an analytical laboratory in Copenhagen, Denmark.

People with "army" numbers exceeding 120 million/ml have significantly longer life expectancy than people with "army" numbers between 0 - 5 million.

They focused on sperm motility, which includes markers like volume and concentration. Each man had his “sperm count” measured — the total number of motile sperm (those that can move or swim) — and then compared that to mortality rates.

During a median follow-up of 23 years, 8,600 people died.

The lower the quality of the sperm, the lower the life expectancy.

The results found that people with "army" exceeding 120 million/ml had significantly longer life expectancy than people with "army" from 0 - 5 million, according to News Medical.

The lower the quality of the sperm, the lower the life expectancy, said lead author Lærke Priskorn, a PhD candidate at Copenhagen University Hospital.

In the 10 years before sperm quality was assessed, men with potentially fatal medical conditions were excluded, he said.

Expert Priskorn said this is the first study to find a link between sperm quality and longevity.

Men with healthy sperm not only live longer but also live healthier.

He also said that a study reported that men with sperm counts of 0-5 million/ml had to be hospitalized 7 years earlier than those with sperm counts of 195-200 million/ml, emphasizing that men with healthy sperm quality not only live longer but also live healthier.

According to experts, a "number" of about 125 million/ml is considered normal. Below 5 million/ml is considered low and is diagnosed as "deficient" and can lead to infertility.

What makes sperm worse?

Professor John Aitken, Director of the Centre for Reproductive Science at the University of Newcastle (Australia), notes that oxidative stress can damage cells, proteins and DNA, and that antioxidant capacity - may be the culprit.

Oxidative stress can lead to lower sperm quality along with other health problems, which is when sperm quality significantly affects male longevity.

To improve sperm count and overall health, the following steps can be taken:

  • Eat a healthy diet (fruits, vegetables, whole foods) rich in antioxidants, which help fight oxidative stress
  • Exercise regularly
  • Avoid alcohol and tobacco
  • Stress Control
  • Limit exposure to toxins (pesticides, heavy metals...)
