Infertility


Impaired fertility or infertility includes the difficulty or inability to get pregnant and/or carry a pregnancy to full term. It is difficult to determine exactly how many people experience impaired fertility. Overall there are more studies about male than female infertility due to the difficulty in finding the right endpoints and measurement techniques. The percentage of women in the US who have difficulty in achieving and maintaining pregnancy has increased between 1982 to 2002. 
The main increase over the last two decades is among women under the age of . There are various causes of impaired fertility. “A woman´s fertility depends on several body parts working together to produce and transport a healthy egg and nurture the developing foetus. Conception and foetal health also depend on the quality of the father´s sperm.” Disorders, which can impair fertility, include abnormal numbers of chromosomes in the eggs, menstrual irregularities, polycystic ovarian failure, and disorders associated with pregnancy, of which the three most common are miscarriage, preeclampsia, and intrauterine growth restriction. Studies have linked fertility problems to exposure to chemicals like DDT, DES, BPA, cigarette smoke and PCBs, and chlorinated hydrocarbons (includes PCBs, some pesticides, dioxins and furans), disinfection by-products, ethylene oxide, glycol ethers, heavy metals, pesticides, phthalates, solvents, PFOS and PFOA, octylphenol and nonylphenol. These chemicals are linked to infertility directly or to various diseases which can lead to infertility among women. One example is endometriosis, a chronic disease where tissue, which lines the uterus, grows abnormally in other locations. This can cause infertility, inflammation and pain. Estimates for the incidence of endometriosis vary. Most of them find that between 10 and 15 per cent of reproductive-age women have endometriosis. Animal studies show a clear link between endometriosis and exposure to organochlorine compounds. A few studies link endometriosis in humans with dioxin, phthalates and PCBs.

 Male infertility is also influenced by chemical exposure. More information can be found in the WHO and UNEP “State of the Science Report on Endocrine Disrupting Chemicals”, and in the ChemTrust report “Male reproductive health disorders and the potential role of exposure to environmental chemicals”.

  2. Infertility is characterized as attempting to get pregnant (with continuous intercourse) for in any event a year with no achievement. Female infertility, male infertility or a mix of the two influences a large number of couples in the United States. An expected 10 to 18 percent of couples experience difficulty getting pregnant or having a fruitful conveyance.
