Endocrine disruptors are thought to cause two diseases
that in turn cause 70% of infertility cases.

More and more women are finding it difficult to get pregnant, with mounting evidence suggesting chemicals such as plasticisers and pesticides are responsible The consequences are estimated to cost the EU €1.4 billion per year. EurActiv Germany reports.
Avoiding chemicals completely in everyday life is impossible, despite endocrine-disrupting substances being considered a health hazard. Moreover, as more women struggle to get pregnant or even discover that they are infertile, there appears to be enough scientific evidence to point the finger at pesticides and plastic products.
As a new study now shows, at least two common female diseases that lead to reproductive difficulties often develop due to substances used in the production of these products.
The scientists involved in the study found endometriosis, a chronic disease of the uterus’ lining, and uterine fibroids, benign tumours in the uterus, are both attributable to endocrine disruptors. Both diseases can cause infertility and are usually very painful.
At least 70% of affected women that suffer from fertility problems exhibit at least one of these two diseases, according to the researchers. The study, published in the ”Journal of Clinical Endocrinology and Metabolism” estimates that the issue costs Europe €1.4 billion euros every year. The bill is accumulated due to healthcare spending and loss of working hours.
The study tested substances including DEHP and DDE. DEHP, a plasticiser, is classified by the EU’s chemicals regulation (REACH) as a “very high concern substance”. Its use in the production of toys and other products intended for use by children is banned. However, EU member states are currently considering authorising the incorporation of DEHP in plastics that would be usable in several consumer products.
DDE, a byproduct of the DDT pesticide, was banned decades ago in Europe. Several studies have shown that some components of the poison build up in the fatty tissues of animals and humans, meaning that they stay in the food chain for a significant period of time.
The fact that pesticides and other pollutants stay in the environment long after their use was recently demonstrated by a study conducted in South-East France, where traces of DDT were found in a soil sample, despite it not having been used for many years. Researchers in the United States have also found that DDT could contribute to the onset of Alzheimers.
Leonardo Trasande, a professor of paediatrics, environmental medicine and public health at New York University warned that: “Although millions of women worldwide suffer from these two gynaecological diseases, we acknowledge that this analysis only shows the tip of the iceberg.” A growing body of evidence tends to suggest that exposure to endocrine disrupters is linked to a wider range of female reproductive problems such as infertility and complications during pregnancy. “These diseases also represent a significant cost to women, their families and society” Trasande added.
“This study adds half a billion to the already amazing bill of €157 billion that Europe has to pay every year because of health problems related to our exposure to environmental hormones,” said Lisette van Vliet, policy advisor to the Health and Environment Alliance. Europeans’ health will continue to be jeopardised if the use of a known toxic chemical is allowed in cheap, poor quality plastic products, especially since “much safer alternatives” to these chemicals are available.
An increasing number of cancer and fertility problems have drawn the attention of researchers to endocrine disruptors. Some call for strict regulation of these substances, in accordance with the precautionary principle.
Other scientists, however stress the importance of these chemicals in everyday products such as plastics. They warn that the foundations of science could be turned upside down, if precautions are taken.
