Strong swimmers can help men enliven competition.
New research suggests that those with higher quality semen can enjoy nearly three years of life compared to their less versatile counterparts.
In short: “The lower the quality of the sperm, the lower the life expectancy,” said Lærke Prisorn, Ph.D., a senior scholar at the Copenhagen University Hospital who helped lead study.
The study, published Wednesday in human reproduction, traced nearly 80,000 men over 50 years.
During that time, 8,600 men died. Researchers found that men who produced more than 120 million moving sperm – capable of moving or “not” lived two to three years longer than those with less than 5 million.
To put it in perspective, high quality sperm men lived on average 80.3 years, while those with the weakest sperm were caught in 77.6 years.
Researchers noted that the potential link between sperm quality and general mortality cannot be explained by diseases diagnosed in the decade leading to tests. It was also not affected by the level of education, which can be an indicator of living factors such as smoking, diet and exercise.
The team speculated that poor sperm quality can signal underlying health problems that affect both fertility and overall well-being-potentially offering an early warning sign on future issues.
“We need to better understand the association between the quality of sperm and the overall health of men,” said Dr. Niels Jørgensen, chief andrologist at Copenhagen University Hospital and leading research researcher.
“However, this study suggests that we can identify the subgroups of men with impaired sperm quality, who are apparently healthy when evaluating their sperm quality, but which are at increased risk of developing certain diseases later in life.”
Researchers now aim to research whether poor sperm quality is associated with previous deaths from specific causes such as cancer or heart disease. They also want to identify the relevant biomarkers to help men’s subgroups at increased risk.
“This is the key to starting the relevant prevention strategies,” Jørgensen said.
‘Canary in the coal mine’
John Aitken, a prominent biologist and professor Emeritus at the University of Newcastle in Australia, who was not part of the study, called him a “landmark” publication.
“In men, it seems to be their sperm profile that is providing the most significant information about their future health and well -being,” Aitken wrote in an editorial published along with the study.
He then raised a question that provokes the thought: “If sperm really are the canals in the male coal mine, the clear question to do is, why?”
Aitken theorized that oxidizing stress could play a role.
Oxidative stress is an imbalance between unstable molecules called free radicals and antioxidants in the body.
When free radicals work properly, they help us protect us from infections. But when their numbers go out of control, they can damage cells and tissues throughout the body.
This speeds up the aging process and can contribute to health issues such as diabetes, cancer and Alzheimer.
“Anydo (genetic, immunological, metabolic, environmental or lifestyle) that increases overall levels of oxidative stress can reasonably be expected to promote changes in sperm profile and subsequent mortality patterns,” Aitken wrote.
Aitken also said that this link can explain why pregnancy complications, such as preeclampsia and gestational diabetes, are associated with the highest mortality of women later in life.
“Perhaps, for both sexes, the secret to reaching both up [fertility] And healthy aging is to monitor oxidizing stress and adopting measures to maintain a balanced redox condition, “he wrote.
To keep control of free radicals, increase your intake of antioxidant -rich foods such as blueberries, broccoli, carrots and leafy greens. Stress management, shortening sun exposure and avoiding smoking and excessive alcohol consumption can also help reduce radical free production.
