In 2050, men may lose the ability to conceive children

In November 2022, it became known thatThe world population was officially 8 billion people. When you consider that back in the 1800s there were only about one billion men and women on our planet, it is easy to understand that we reproduce very well and rapidly. However, in the future, the situation may change for the worse - researchers recently shared the disturbing news that by 2050 the number of infertile men in the world could greatly increase. They came to this conclusion after studying the health data of 57,000 people from 53 countries. Let's find out the details about the scientific work carried out and try to figure out what is so bad for the ability of men to conceive children.

Study finds many men of the future will not be able to experience the joy of fatherhood

How men change over the decades

Studying the ability of men to conceive childrenstarted in 2017. At that time, experts were only able to assess the health of residents from North America, Europe, Australia and New Zealand. The study showed that over the past four decades, the quality of men's sperm has deteriorated by half. Consequently, it could be said that over the course of nearly half a century, many men were at greater risk of suffering from infertility. This is a very loud statement, however, due to the limited sample of people, few people paid attention to the results of this scientific work.

Scientists have concluded that men's health has worsened over the past 40 years

In 2022, scientists shared newresults that were based on data on 57,000 men from 53 countries. Information about their ability to conceive children was taken from 223 different scientific papers. This research has become more serious, and its results clearly deserve more attention from scientists and society.

Infertility in men may become widespread

Overview of the results of more than two hundred studiesshowed that between 1973 and 2018, the concentration of male spermatozoa decreased from 101.2 million to 49 million per milliliter of seminal fluid. It turns out that the results of a study conducted a few years ago were correct - the quality of men's sperm was reduced by half.

For almost half a century, the quality of men's sperm has fallen by half

The authors of the scientific work noted that the numberspermatozoa in men in the 21st century continues to decline at an enormous rate. According to the results of the study, every year their concentration decreases by 1.1%. If this process is not affected, far fewer children will be born in the world in the future. According to Contrymeters, 440,000 babies are born every day in the world, but this number could be halved in the future. Given the rate at which male fertility is declining, the effects could be felt as early as 2050.

Cause of infertility in men of the future

Experts announced that in order to preventfurther violation of male reproductive health, humanity needs to take action right now to correct the situation. But no one knows what to do - scientists cannot name the exact reason for the increased risk of infertility in men. The reason for all this can be environmental pollution, alcohol consumption, a sedentary lifestyle, a love of fast food and sweet soda, and much more. In addition, scientists still know little about the effect of electronic cigarettes on the human body - maybe the reason is in them?

Scientists still do not know the reason for the decline in male fertility

In addition, it should be noted that the abilityMen to conceive children are affected not only by the number of spermatozoa - their mobility is also very important. WHO experts believe that 15 million spermatozoa are enough to conceive a child in a milliliter of seminal fluid. In this regard, it's still not so bad, 49 million sperm is a good indicator. It is alarming that their number is declining every year, and no one knows how to stop it. Also, we still do not know how things are with sperm motility - scientists have not studied this issue.

A man's ability to conceive a child depends not only on the number of spermatozoa, but also on their mobility.

That in the future fewer men will be able to experiencethe joy of fatherhood sounds scary. But some scientists are skeptical about the results of the new scientific work. For example, Allan Pacey from the British University of Sheffield believes that his colleagues do not take into account one important detail. In the 1970s, the technique was less advanced and researchers could get a single number. Today, the equipment at the disposal of scientists is more accurate, because of which completely different numbers are obtained. Because of this, one can erroneously conclude that in the past the health status of men was better than today.
