What the heck are endocrine disruptors?

Endocrine disruptors are chemicals that may interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in humans. Many substances, both natural and man-made, are thought to cause endocrine disruption.

How do endocrine disruptors impact women?

Disrupting the Cycles of Life. EDCs can also affect the duration of fertility. In girls, early life exposure to DDT may contribute to an earlier onset of puberty; once they become adults, this exposure may also lengthen menstrual cycles and accelerate menopause. Lead, another reproductive toxicant, may shorten a woman’s reproductive lifespan.

What causes endocrine disruption?

• Chemical exposures during development can alter disease susceptibility later in life.
• Endocrine disrupting chemicals (EDCs) can produce adverse developmental, reproductive, neurological, cardiovascular, metabolic and immune effects in humans.
• EDCs interfere with the synthesis, secretion, transport, activity, or elimination of natural hormones.

What does an endocrine disruptor do?

Endocrine disruptors can affect the body in three main ways: They may block the pathway between a natural hormone and a receptor. They may act directly on a gland, causing it to make too much or too little of a hormone. They may mimic a hormone, causing the body to overreact or to react at the wrong time.

What are Examples of Endocrine Disruption?

One example of the devastating consequences of the exposure of developing animals, including humans, to endocrine disruptors is the case of the potent drug diethylstilbestrol (DES), a synthetic estrogen. Prior to its ban in the early 1970's, doctors mistakenly prescribed DES to as many as five million pregnant women to block spontaneous abortion and promote fetal growth. It was discovered after the children went through puberty that DES affected the development of the reproductive system and caused vaginal cancer.

How does the endocrine system disrupt?

Some chemicals mimic a natural hormone, fooling the body into over-responding to the stimulus (e.g., a growth hormone that results in increased muscle mass), or responding at inappropriate times (e.g., producing insulin when it is not needed). Other endocrine disruptors block the effects of a hormone from certain receptors (e.g. growth hormones required for normal development). Still others directly stimulate or inhibit the endocrine system and cause overproduction or underproduction of hormones (e.g. an over or underactive thyroid).

What are the effects of chemicals on wildlife?

Prior to its ban in the early 1970's, doctors mistakenly prescribed DES to as many as five million pregnant women to block spontaneous abortion and promote fetal growth. It was discovered after the children went through puberty that DES affected the development of the reproductive system and caused vaginal cancer.

Can chemicals affect the endocrine system?

In recent years, some scientists have proposed that chemicals might inadvertently be disrupting the endocrine system of humans and wildlife. A variety of chemicals have been found to disrupt the endocrine systems of animals in laboratory studies, and there is strong evidence that chemical exposure has been associated with adverse developmental and reproductive effects on fish and wildlife in particular locations. The relationship of human diseases of the endocrine system and exposure to environmental contaminants, however, is poorly understood and scientifically controversial (Kavlock et al., 1996, EPA, 1997).

The World Health Organization (WHO) defines an endocrine disrupting chemical as “an exogenous substance or mixture that alters function (s) of the endocrine system and consequently causes adverse health effects in an intact organism, or its progeny, or (sub)populations.”

What are regulatory decisions about chemicals that may affect the endocrine system?

Regulatory decisions about chemicals that may affect the endocrine system need to be based on a combination of factors – whether a chemical causes endocrine-related activity; what is the chemical’s potency and levels and means of exposure; whether it produces adverse effects and if so, at what dose levels; and what is the life-stage and susceptibility of an individual.

What is the interaction between the endocrine system and substances that are endocrine-active?

In some cases, the interaction between the endocrine system and substances that are endocrine-active is neutral: the substances lack sufficient potency, or exposures may be so low that no effects occur at all.

What is the OECD?

The Organization for Economic Co-operation and Development (OECD) and the U.S. Environmental Protection Agency (EPA) have developed scientifically-validated screens and tests for identifying chemicals with endocrine active properties to enable science-based examinations of the endocrine disruptor issue. Due to these efforts, regulatory agencies today have access to toxicological screening test guidelines that are relevant, reliable, sensitive, and specific for evaluating the potential for substances to interact with the estrogen, androgen, and thyroid pathways.

When screening substances for endocrine-related activities, especially when using emerging technologies, must regulatory agencies use?

When screening substances for endocrine-related activities, especially when using emerging technologies, regulatory agencies must use validated methods so the results can be relied upon and trusted by all stakeholders.

Is an endocrine disruptor harmful?

The likelihood that an endocrine disruptor will cause harmful effects is based on its potency (how active it is) and potential for exposure (dosage, frequency, and duration). The definition is important so as not to confuse neutral “endocrine effects” with negative “endocrine disruption,” with the latter term being linked to adverse/negative health ...

Can natural substances interact with the endocrine system?

Certain natural substances, in addition to some synthetic chemicals, can be shown to have the potential to interact with components of the endocrine system while not causing any changes in function of the organism whatsoever; or they may cause transient effects which are readily reversible and do not result in adverse health effects.

The true effect of low dose exposure to endocrine-disrupting chemicals on the development and progression of cancer is unknown, but there is evidence showing a cause for concern. Fortunately, there are many simple changes people can make to reduce their exposure daily, and there may even be additional benefits to these changes with regard to the environment and your general sense of wellbeing.

What are the human impacts of EDCs?

Attention has focused on health problems arising when EDCs interfere with estrogens, androgens, and other sex hormones and the thyroid hormones.

How do endocrine disrupting chemicals affect the human body?

Our understanding of how endocrine disrupting chemicals (EDCs) interfere with hormones and other chemical signalers is growing rapidly. Once thought to primarily interfere with hormone receptors, we now know the culprits impact a wide range of signaling processes. They can interfere with hormone binding, transport, and production; gene expression; and a host of other cell regulatory mechanisms. These disruptions may affect the endocrine, immune and neural systems and may lead to developmental, reproductive, metabolic, brain, and behavior problems.
