Infertility increases or decreases in women
Are we going to be sterile soon?
Concerning environmental effects on reproduction
Gabriel André is a gynecologist and a member of the Scientific Council of the European Bioethics Forum.
For the gynecologist Gabriel André, it is an incontrovertible fact: The combined effect of endocrine disrupting factors and pollutants in the air and food is responsible for the fact that fertility in humans decreases and cancer types affecting women occur more frequently.
For him there is also a "clear connection between the dirt particles, especially from diesel engines, and a declining child's brain volume. "The environmental toxins affect normal development already in the fetus stage. In 2015, the magazine Jama Psychiatry published the results of a study of 40 children born in Harlem between 1998 and 2006. Soe were exposed to a high degree to polycyclic aromatic hydrocarbons (PAH for short). These arise from the combustion of fossil fuels, wood and tobacco and are contained in the air we breathe and in food.
The study shows the negative effects of PAHs on brain development even in the fetal stage. The more a baby was exposed to PAHs, the less the white matter develops, which among other things helps with learning - it is also almost exclusively restricted to the left hemisphere. The researchers observed the children up to the age of seven and found the following effects:
- at the age of three: Lag in development
- at the age of five: lower IQ
- at the age of seven: Anxiety, depression, attention deficit disorder, and slow information processing
Endocrine Pertubators - Death by Installments
André Cicolella is a chemist, toxicologist and founder of the Réseau Environnement Santé (RES) (Network Environment and Health). He was a driving force behind the bisphenol A (BPA) ban in France and has published numerous specialist books.
Another research result: The concentration of sperm in the seminal fluid has decreased by half in the last forty years. This information comes from a meta-study in which researchers evaluated 185 individual studies. It appeared in the journal Human Reproduction Update. The French researcher André Cicolella comes to a similar conclusion in his book Toxique planète (“Poisonous Planet”), based on a study by the French health authorities from February 2012. It evaluated the data of 26,609 men who sought medical assistance with reproduction in France between 1989 and 2005. Conclusion: In 35-year-old men, the total number of sperm has decreased by 32 percent, while that of malformed men has increased. "If this development continues at the same pace, we will have reached zero in 2040", notes André Cicolella. He initially understands this as a warning; the trend does not necessarily have to continue. It is already clear, however, that infertility is growing.
Like many of his colleagues, Cicolella attributes this primarily to the so-called "endocrine disruptive factors". Omnipresent pesticides, cosmetics and plastics secrete particles that we ingest every day, through touch, when we eat and when we breathe. An example: bisphenol A, contained in all food packaging in France until 2015. Cicolella led the successful fight for a ban in the food industry in France - but it can still be found in glasses or CDs to this day, in Germany it is only banned in baby bottles. It is one of the substances that change the normal behavior of hormones such as testosterone or estrogen.
As a result, they disrupt physiological processes such as the growth of the fetus, breastfeeding or reproduction. Its exact effects cannot yet be clearly assessed. However, they have been shown to make reproduction difficult by promoting disorders such as precocious puberty, genital malformations, endometriosis, polycystic ovary syndrome, or breast cancer.
