It has an impact on natural fertility, but I hope people realize that chemicals do play an important role in it. “
This environmental and public health expert and colleagues have obtained multiple evidences in past research. Phthalates can turn hard plastics into elastic plastics, and are often used as plasticizers. Plastic products containing this substance often appear in food production, processing and packaging processes in. It lowers testosterone levels and reduces sperm count, so it has a greater impact on men. But this does not mean that women can be protected from it. Past studies have found that this substance can lead to early puberty, premature ovarian failure, miscarriage and premature delivery. Bisphenol A is a plastic hardener that was once used to make baby bottles and often appears in the inner coating of food cans. As an estrogen analogue, it is self-evident that it interferes with the female reproductive system, and men who have occupational exposure can not escape the impact-the decline in sperm quality and the increased probability of erectile dysfunction are all related to this.
But these are not the greatest harm to humans caused by endocrine disruptors. If a pregnant woman is exposed to endocrine disruptors in the early stages of pregnancy, for fetuses whose cells are undergoing reprogramming, such adverse effects may continue throughout their childhood, adolescence, and adulthood.
For example, the air that a mother-to-be breathes, the water she drank, the food she eats, and the skin care products she uses will bring these toxic substances into her body. If the mother is exposed to substances that can block the action of male hormones in the early pregnancy, the anogenital distance (anogenital distance) of the male fetus may be shortened. Studies have shown that a shorter anogenital distance is related to a shorter penis and a lower sperm count in adulthood. In addition, interference with the male hormone system during the prenatal period may lead to lower testosterone levels, increased risk of congenital cryptorchidism and hypospadias. If a boy is born with these genital defects, he also faces a higher risk of low sperm count and testicular cancer as an adult.
An article recently published in the “American Journal of Public Health” (American Journal of Public Health) reveals endocrine disruption The relationship between objects and children’s neurodevelopmental damage. This review article summarizes the 30 countries in 11 countries around the world as of 2019.A number of studies have investigated the situation of women’s exposure to different types of phthalates before childbirth and after the birth of their children. The results found that phthalate exposure is strongly associated with children’s aggressiveness, provocation, emotional overreaction, illegal behavior, and other attention deficits and other symptoms of ADHD. One of the studies found that mothers with the highest levels of phthalates in their urine during the second trimester were three times more likely to have ADHD than those of mothers with low levels. Children exposed to higher levels of phthalates in the womb have an IQ that is 7% lower than other children, and their perceptual reasoning and language comprehension abilities are also lower.

In addition, endocrine disruptors are also autoimmune diseases, obesity, metabolic syndrome(multiple cardiovascular and cerebrovascular disease risk factors in the same individual Clustered clinical syndrome) is one of the reasons why it is becoming more common.
The above-mentioned problems have brought great challenges to the continuation of mankind. This means that it is time to turn our attention here. We should give priority to using substances that do not affect hormones and are easily decomposed in the environment to replace endocrine disruptors in daily products. At the same time, we also need to establish more effective testing methods and restrictions to ensure that the chemicals that enter the market and enter our bodies are safe. In other words, we need to stop treating ourselves and our offspring as mice that are endocrine disruptors. This is related to the health and future of all mankind.
