In the 60s, large families were more frequent than today ! Economic conditions and changes in women’s work may explain this phenomenon. But according to Shanna Swan, professor of environmental medicine in New York, lifestyle choices and the current economic mode do not explain the loss of fertility in humans.
Shanna Swan explains it by the presence of plastics and chemicals in our daily lives. This study alarms the overconsumption of plastic in industrialized countries … And affirms thatin 2045, we will no longer be able to ensure the survival of the human species through procreation!
To support her remarks, Shanna Swan, published in 2017 in Human Reprodution, a study which alarm on the fertility rate of men. In 40 years, the sperm count of western men would have fallen by more than 50%. In a recently published book, Count Down, she explains that this mind-blowing drop in the ability to procreate isn’t just a lifestyle choice! To say that people no longer have children because they have chosen him is not, according to her, the only reason. For her, the cause is chemical explains the site The Guardian!
A very telling comparison
In 1973, a man had about 99 million sperm per ml of semen. In 2011, this rate was only 47.1 million! That is a decrease of 53.4% among men living in Western countries (Australia, Europe, North America). “The sperm count in men has more than halved over the past 40 years” says The Guardian.
Also according to Shanna Swan, this decrease could be explained in part by the interference of sex hormones with chemicals. She points to phthalates, which are used to make plastic more flexible. And she explains that these phthalates lower testosterone and therefore decrease the number of sperm. At the same time reducing male fertility. And in women, these phthalates are said to cause precocious puberty, ovarian failure, miscarriages or premature births.
Swan predicts that the world will be infertile in 2045 but it also offers some ways to change the situation! “Reproductive problems cannot last any longer without threatening human survival”Swan explains in Count Down. Besides the fact that the chemical industry is finally developing new non-hormonal products for domestic use. She believes that not introducing Teflon, BPA or phthalates in the diet of people of childbearing age could greatly reduce the risk of infertility!
