"Question. What are endocrine disruptors? Answer. They are chemical substances which, once inside the body, modify its hormonal balance. Hormones are the messengers that communicate between, for example, the ovary and the breast, as does estradiol, which is an estrogen. Disruptors can mimic estradiol and compete with that message, distorting it. They are hackers that alter hormonal messaging. Q. Do they have immediate effects? A. The effect is certainly immediate, because the alteration is instantaneous, but the repercussions of adverse effects can be very long-term:"
"The consequences are not visible until adulthood, so it is difficult to establish causality. In our study on poor semen quality, the prevailing hypothesis is that it was defined in the first 40 days after the child's fertilization. Q. What other effects do they cause? A. Thyroid disorders there are a huge number of people taking thyroid hormone for hypothyroidism weight gain and diabetes, infertility."
Endocrine disruptors are chemical substances that enter the body and modify hormonal balance by mimicking or competing with natural hormones such as estradiol. The alteration of hormonal messaging can be instantaneous, yet adverse consequences often appear only in adulthood, complicating causal attribution. Early exposures can condition adult health and reproductive outcomes, with some impairments hypothesized to be set within the first 40 days after fertilization. Known effects include thyroid disorders, weight gain, diabetes, and infertility, and poor semen quality has been linked to early-life exposures. Bisphenol A is a widely studied example among many ubiquitous everyday-product chemicals.
