Twelve percent of the reproductive age population in the United States report trouble conceiving and/or carrying a pregnancy to full term.

Reproductive health is affected by many factors, but recent scientific evidence indicates that certain pollutants in the environment, drinking water, food supply, and common household goods may also play an important role in human fertility and reproduction in both men and women.

Though research is on-going, reproductive environmental health researchers and clinicians agree there is already a substantial body of evidence implicating low-level exposures to contaminants as a likely contributor to trends currently seen in reproductive health outcomes.

Reproductive Health Symptoms and Conditions Linked or Suspected to be Linked to Environmental Contaminants

Studies suggest links between environmental contaminants and reproductive system dysfunction. A host of symptoms and conditions are linked or suspected to be linked to exposure to heavy metals and synthetic chemicals, including pesticides.
These include, among girls and women:

  • Premature ovarian failure
  • Malformed reproductive organs
  • Early or delayed menarche (first menstrual period)
  • Infertility or compromised fertility
  • Recurrent pregnancy loss
  • Inability to carry baby to term, birth defects, and low birth weight
  • Damage to fetal reproductive organs
  • Premature menopause
  • Uterine fibroids

Among boys and men, key trends in reproductive health include:

  • Undescended testes or malformed reproductive organs
  • Compromised sperm shape and quality, including issues of mobility, motility, and genetic integrity
  • Testicular dysgenesis syndrome, or TDS, is a suspected cluster of effects (undescended testes or malformed reproductive organs, testicular cancer, and decreased sperm quality) with a hypothesized common fetal origin, such as exposure to toxic chemicals in utero.

Exposures In Utero

Pregnant Woman

Researchers have found that exposures encountered in utero can shape the subsequent reproductive health of adults. Clinicians and scientists now know that the placenta does not shield the developing fetus from many chemicals or pollutants the mother encounters.
A body of evidence now demonstrates that many chemicals that people routinely encounter in the environment can mimic or interact with the endocrine (hormone) system, and can affect the fertility and reproductive health of offspring. These chemicals are referred to as “endocrine disruptors.”

How Are We Exposed, and How Can We Limit Our Exposure?

Certain contaminants found in food, personal care products, household cleaners, plastics and tobacco smoke have been linked to reproductive health concerns.

  • Food – A number of pesticides have been linked to reduced fertility and menstrual irregularities in women, and hormonal changes and reduced fertility in men. If possible, grow your own food without the use of synthetic chemicals. Otherwise, purchase organic food at your grocery store if it is available. If you harvest wild foods for subsistence, be aware that certain contaminants accumulate in the Arctic marine food web and are most highly concentrated in the fatty tissue of animals.To learn more about toxic chemicals in foods and ways to reduce your exposure:
    • Visit the food section of our website
  • Personal care products – Many cosmetics and other personal care products contain chemical additives that have been linked to reproductive health effects. Phthalates (pronounced ‘thal-lates’) are a group of chemicals that can be found in lotions, soaps, hair products and cosmetics. Phthalate exposure can begin in utero and, in one study, is strongly associated with shorter pregnancy duration. Phthalate exposure in utero has also been linked to altered male reproductive development.To learn more about chemicals in personal care products:
  • Plastics – Chemicals found in plastic products such as food containers, baby bottles and toys have been linked to infertility and other reproductive health problems. Using glass, ceramic or wooden products will reduce your exposure to these chemicals. If you must use plastic, avoid plastics marked #7 (these are likely polycarbonate plastics that contain the chemical bisphenol-A) and #3 (which are made with polyvinyl chloride (PVC). Avoid using plastic wrap and heating plastic containers in the microwave oven.To learn more about toxic chemicals in everyday products:
  • Household cleaners – Many cleaning products contain chemical solvents and fragrances linked to infertility and other health problems. You can buy non-toxic cleaners or make your own using vinegar, baking soda and borax soap. Water-based paints, glues and citrus-based cleaners are safer to use.To learn more:
  • Tobacco smoke – Tobacco smoke contains thousands of chemicals, many of which are poisonous. Even if you do not smoke, you can be harmed by secondhand smoke. New evidence suggests that you can even be exposed to chemicals from tobacco smoke long after a person who was smoking has left an indoor area. Thirdhand smoke is a new term for tobacco toxins that remain and persist after a period of active smoking. These chemicals are deposited on surfaces such as tables, furniture and floors, as well as in dust.To learn more:

Remember these five ways to reduce your exposure to chemicals that harm reproductive health:

  • Know your food
  • Know what’s in your personal care products
  • Be informed about plastics and avoid microwaving in plastic
  • Select non-toxic household cleaners (or make your own)
  • Avoid tobacco smoke

Why should Alaskans be concerned?

Below are some startling issues we face, with links to their scientific sources. Although we do not know the correlation between each of these issues, the reality is, Alaskans are facing environmental exposure to chemicals which are not even manufactured in Alaska. The way that the law stands now, it is up to us to prove that each individual chemical (of over 80,000 chemicals) causes us harm.

It is time to turn the tables and require companies to prove the safety of a chemical before it’s manufacture.

Issue: In Alaska, the rate of major birth defects is twice as high as the rest of the United States:

Cardiovascular anomalies were the most common birth defects, comprising 38% of all affected infants… We found the birth prevalence of MCAs (major congenital abnormalities) in Alaska to be twice as high as the 3% reported for the United States as a whole…Our data indicates that Alaska Native infants have twice the risk of MCAs as white infants… Controlling for identifiable risk factors did not explain the racial disparity. Birth defects are caused by complex interactions between genetic and environmental influences; causal pathways for most birth defects are unknown.

An increasing number of peer-reviewed scientific studies demonstrate that toxic chemical exposure is an important risk factor, not only for birth defects such as oral clefts, heart abnormalities and underdeveloped brains but also for other serious illnesses including cancer, asthma and reproductive problems.

We need to establish laws that regulate chemicals that cause neurological damage, cancer, genetic harm, endocrine disorders or harm to the immune system. Children are especially vulnerable to the harmful effects of chemicals, and we should do everything we can to protect them.

If we do not act now, we will face grave consequences in the health of future generations. We need to give a voice to our children and grandchildren and stand up against harmful pollutants that could destroy their chance at a better life. Together we can urge Alaska’s senators to protect our families by supporting the Safe Chemicals Act of 2011. We have no time to waste.
