Beware of Chemical Substances Around the Annoying Fertility

           The chemicals are easily found on food packaging, pesticides, clothing, carpets, upholstery, and various care products, the effect delaying pregnancy. Thus the news written HealthDay News recently. The use of chemicals had been banned in the US because of the toxic, and is expected in 2010 really is not used anymore.

However, these substances had already wandering in the environment and in our bodies for decades. "The chemical is already widespread impair fertility, thus making it difficult to have a baby," said Dr. Jorn Olsen, chief researcher and head of the Department of Epidemiology, UCLA's School of Public Health.

The Danish women in the study who had perfluorooctanoate (PFOA) and perfluorooctane sulfonate high levels (PFOS). As a result, they have to wait long to get pregnant.

The report is published in the online edition of Human Reproduction, late last month. And followed by the emergence of various reports about the dangers of other chemicals present in plastics, such as bisphenol A (BPA), which can cause problems in the fetus or infant.

For the study, Olsen's team collected data on 1,240 women in the Danish National Birth Cohort. Researchers took blood samples from the women and interviewed them on how long they waited for the pregnancy. Found the levels of PFOS in the blood of 6.4 nanograms per milliliter (ng / ml) to 106.7 ng / ml. For PFOA range 1 ng / ml to 41.5 ng / ml.

Olsen and his team then divided the women into four groups, depending on how much of the chemicals in their blood. Women in the group with the highest levels of PFOS, 70-134 percent longer to get pregnant than women with the lowest PFOS levels. Women with the highest PFOA levels 60-154 percent longer to get pregnant compared with women with the lowest levels.

Researchers claimed not to know exactly why these chemicals inhibit pregnancy. However, they estimate it all related to the disruption of hormones that are involved in reproduction.

Recent animal studies have revealed these chemicals have toxic effects on the liver, immune system and reproductive organs. The study also found that PFOA and PFOS to impaired fetal growth.

Other dangers involve these chemicals may soon become a debate. Since 2006, the US Environmental Protection Agency (EPA) is committed eight factories that voluntarily reduce PFOA emissions and product content of PFOA in them.
