Due to the presence of toxic chemical compounds in everyday objects, food, beverages and the air we breathe, the concentration of human sperm has dropped by nearly 60% since the 1970s. A similar decline has been seen in dogs and other animals. If this trend continues, we will face the risk of infertility by 2060.
The study “Time Trend of Sperm Quantity: A Systematic Review and Meta-Regression Analysis” published in the journal Human Reproduction Update in July 2017 showed that in the half century from 1973 to 2011 sperm in people It dropped drastically by approximately 60%. The meta-analysis involved 200 searches, searching for a total of more than 40,000 “sampled” men.As noted by Professor Shanna H. Swan, a reproductive epidemiologist at the Icahn School of Medicine at Mount Sinai, New York, the co-author of the study Collapse Attributed to Chemical material Around us-especially Phthalates -And affect our Endocrine System, Has a significant impact on reproductive capacity.If this reduction continues in the next few decades, we may encounter a situation where the sperm concentration is so low that Fertility. In other words, this situation is threatening the survival of mankind. Human species.
Emphasize this in the article Published in The Converstaion The two scientists are Alex Ford and Gary Hutchison, professor of biology at the University of Portsmouth, and the latter teaches toxicology at Napier University in Edinburgh, where he serves as the head of the Department of Applied Sciences. The two researchers drew an X on the “calendar”, thinking that if the downward trend is determined (1-2% per year), humans will no longer be able to produce enough sperm to reproduce by 2060. Professor Swan said “reciprocal“His own book specifically addresses this subject, accurately referring to the moment when the threat to the survival of our species will become concrete. According to Swan, as early as 2045, most couples will need Auxiliary fertilization Consider nature sexual intercourse It will become more and more complicated.
As the author of the article explained, not only the diffusion of compounds affects reproductive capacity, but free radicals also affect reproductive capacity. Lifestyle changes Abuses that have occurred in the past 50 years alcohol, This Sedentary lifestyle with Unbalanced diet These are increasingly common behaviors; these are all factors that may affect reproductive capacity.but Disruptors or endocrine disruptors Ford and Hutchison pointed out that “phthalates” (endocrine-destroying chemicals-EDC) are now everywhere, “in food, beverages, personal care products and the air we breathe.”This is a continuous exposure, you can also change it Fetal development.Embryos in the womb are “bombed” by toxic chemicals, which were not widely spread half a century ago and have also increased abortion.
The influence of these substances will also affect other substances animal, As a pair puppy “Environmental chemicals in dog testicles reflect its geographic origin and may be related to pathological changes“Published in “Scientific Reports.” Scientists led by Professor Richard G. Lea show that humans’ best friends also suffer from the same sperm drop as humans. No wonder considering that we share the same environment. Research Visoni Raised animals have seen an increase in transmission Genital deformities, Its spread is more obvious in animals exposed to animals Waste water (For example, Chinese alligators and some crustaceans and fish) are contaminated by our toxic chemicals.Institutions such as the European Union are taking more stringent measures to regulate their existence substance In everyday products, it is especially necessary to avoid replacing harmful substances with equally harmful compounds (as has happened in the past), but if we cannot intervene more effectively (such as we are trying to use plastic and carbon), then our species Will be severely endangered within a few decades.
