Reproductive Apocalypse

Reproductive Apocalypse

No, no, don't be scared. He has not come yet. But scientists are already showing serious concern. And this concern is connected with the rapidly decreasing sperm count in the male half of modern humanity. Until now, no significant research has been carried out to identify the problem, which in fact has become more and more obvious every year.

Agree, talking about the sexual health of man, we used to talk more about women and their fertility, but always somehow less emotionally and interestedly recall in this regard about men.

The situation has changed. The professional public, urologists, anthropologists, human rights defenders and other caring people talked with anxiety that fertility is not only women, but equally men, their sexual health, their fertility, the health of their sperm as the main biomaterial involved in human reproduction.

And finally, recently, the results of a meta-analysis of a large group of scientists from different countries of the world were published, coordinating and simultaneously conducting research on various aspects of this problem. The main disappointing conclusion indicates a potential decline in men's health and the associated childbirth.


According to scientists, the number of sperm in men from America, Europe, Australia and New Zealand has fallen by more than 50 percent in less than the last 40 years.

The results of this study are a call for health authorities around the world to immediately begin work on studying the causes of the sharp decline in sperm count in modern males.

The analysis did not reveal any reasons for the decline, but the researchers state that a sharp decrease in the number of spermatozoa is associated with many unfavorable factors, such as exposure to the body of certain chemicals and pesticides, smoking, stress and obesity.

This suggests that sperm quality may reflect the influence of modern life on men's health and act as a “cuckoo on the wall clock”, signaling broader health risks.

The analysis indicates a decrease in the number of sperm cells since the early 1990s, but many of them were questioned because they did not take into account potentially serious common factors, such as age, sexual activity, and the types of men involved in the experiments.

Working with a team of researchers from the USA, Brazil, Denmark, Israel and Spain, Dr. Hagai Levin, the lead author of the study at the Jerusalem Medical University, checked and collected 185 sperm tests for all the years of the experiment, and then carried out a so-called meta-regressive analysis.

The results, published in the Human Reproduction Update journal, showed a decrease in sperm concentration by 52.4% and a decrease in the total number of sperm in men from North America, Europe, Australia and New Zealand by 59.3%.

The first indicator reflects the concentration of sperm in human ejaculation, while the latter is the concentration of sperm multiplied by the volume.

In contrast, no significant decline was observed in South America, Asia and Africa. However, researchers noted that much less research was conducted in these regions.

Daniel Brison, a specialist in embryology and stem cell biology at the University of Manchester in Britain, argues that the results "are of great importance not only for fertility, but also for men's health and the wider public health." He also notes that there is still the unanswered question, “will the causes of the decrease in the number of sperm cells affect future generations of children through epigenetic modifications or other mechanisms operating in the sperm?”

Another expert, Richard Sharp from the University of Edinburgh adds: “Given that we still do not know which way of life, dietary or chemical effects could have caused such a decline, research efforts to identify these causes need to be doubled, and the results must be predictable.”

So, the authors of the study announce an emergency in the field of public health in connection with the problem of reducing the total number of spermatozoa and the deterioration of their quality.


The Internet community, known as the Manosphere, which unites men experiencing problems with reproductive function, uses the results of published scientific studies as evidence that they are violently feminized by modern society. The followers of this movement are convinced that men can thus completely lose the ability to reproduce within a single generation.

In order to make the discussed problem more understandable, let's try in a few sentences to go through a short popular course of the section of medicine that interests us.

Sperm are reproductive cells that are produced in the male gonad, i.e. testicles. Figuratively speaking, an egg is a cauldron that constantly produces sperm. Produced sperm as a good wine must be stored and maintained for 72 days before the sperm are ready to travel.

At the completion of the developmental stage, sperm is released from the testicles through a system of canals that push them out of the penis during ejaculation, along the way the sperm includes enzymes and other necessary ingredients.

When doctors check the quality of sperm using analysis, they pay particular attention to:

  • Sperm count (or sperm concentration):

an egg that contains at least 15 million sperm per milliliter is more likely to fertilize the egg, i.e. This is a level of fertility concentration that is sufficient for men looking to have children.

  • Speed:

In order to reach the seed-conductive paths, the sperm must be fluid, therefore motility is another key condition. A man who has at least 40% of sperm cells is motile is more likely to be conceived.

  • Morphology:

The form of sperm also matters. They should look like tadpoles immortalized in Woody Allen's funny movie “Everything you always wanted to know about sex, but were afraid to ask,” with small oval heads and long tails. If a man is the owner of the sperm of the classical form, his chance of conceiving a healthy baby is definitely high.


Well, the educational program is over. But the question remains: are these parameters sufficient? Of course not.

The results of the analysis of semen on the quality of the same person may differ from the sample by 100% percent, since most often this is determined by the lifestyle of the man. This is especially true of such an indicator as morphology. Habits such as alcohol, tobacco, saunas, etc. Pernicious addiction can significantly change the quality of sperm, so a person's sperm can look very different depending on what he did shortly before conception. The quality of sperm also can not always provide unconditional conception. Scientists have discovered that some men with relatively low sperm count can conceive, while others with more abundant sperm cannot. And it still remains the great mystery of human nature.

Despite a detailed and systematic meta-analysis, there are still a lot of white spots in this extremely serious area of reproductive medicine, because the researchers used only methods known to them that have not changed for years, for example, methods of counting spermatozoa in different conditions and circumstances, using hemocytometer, etc.

But one thing is clear: in the early 1970s, when the research started, men had an average of 99 million sperm per milliliter of sperm. Now that number has dropped to 47 million per milliliter. Thus, every year, the number of male sperm cells decreased by about 1 percent “without any signs of leveling.

It was the most comprehensive and grandiose study of the problem over the entire existence of reproductive medicine and male sexual health medicine, and its findings clearly indicate that, of course, the number of spermatozoa in a modern man is decreasing and this is not the best indicator of the health of a man as a whole.

Expert opinion


Here is the opinion of the Director of the Men's Reproductive Health Program at the US National Institutes of Health (NIH), PhD Stewart Moss:

The quality and quantity of sperm is increasingly seen as an indicator of the overall health of men. Thus, even beyond the conception of a man to conceive, there is an interdependence between poor sperm quality and poor health.

In one interesting article that appeared in one of the professional journals for 2009, the results of a survey of 40,000 men who were looking for various ways to treat infertility were published; scientists have found a striking correlation between good sperm quality and a lower risk of death. In particular, the following article was written in that article: “Mortality decreased with an increase in the percentage of normal and mobile sperm. Mortality also decreased with increasing sperm concentration to a threshold of 40 million / ml, which reflects the detection of the ability to conceive. "

From a number of epidemiological studies, it can be seen that male fertility may be a determining factor in his overall health. Thus, a low percentage of sperm is a concern in a number of geographic areas. If the trend continues, at some point in time we will be able to face a decrease in fertility. But here and now a more serious issue is that it may be an indicator of poor health in general.


Here’s the opinion of another expert on male infertility. Paul Turek, Researcher at the University of California:

A serious problem is that over the past 50 years there has been a significant increase in the number and volume of chemicals that are released into the environment. In addition, most of the food we eat and everyday items that we use are stored or used with plastics containing human-made chemicals. These chemicals are also present in our creams and cosmetics, our house cleaning products, as well as our medicines and medical devices. They penetrate our food and water, the environment and our bodies.

Treat your body like a temple. Imagine that you are preparing for high-speed races. Need to take care of yourself. Eat well. Sleep well and calmly. Reduce stress. Doing physical exercise. Eat healthy and healthy food. Regularly, but prudently have sex. Remember, sperm count and sperm quality are the biomarker of your health.
