Two chemical compounds of sunscreen allegedly defective male fertility

Some US researchers on Friday, November 14, 2014 said the two chemicals that are used to protect the skin from ultraviolet (UV) seems to be able to impair the ability of men to be fathers.

These chemicals, known as Benzophenone-2, or BP-2, and 4OH-BP, each of which could result in a 30 percent decrease in male fertility, biological ability to reproduce, say the researchers of the National Institutes of Health (NIH) and the Department of Healths Wadswoth Center in the State of New York.

It could be happens because the chemicals are absorbed by the skin, can interfere with the body's hormones and the endocrine system. Lower fertility rates that may result in more length of pregnancy, the researchers said in the American Journal of Epidemiology.

BP-2 and 4OH-BP contained in the composition of the group called ultraviolet filter BP-Type, that made up a total of 29 classes of chemicals are commonly used in sunscreen and other personal care products to protect skin and hair from sun rays.

The researchers studied 501 couples who trying to have children, and follow their progress to become pregnant or for one year effort to record the women time required for pregnant, as reported by Antara on Saturday, November 15, 2014.

They also examine the urine sample and measuring the content of selected five UV filter and associated with endocrine disrupting activity. The female test participants aged between 18 and 44 years, and the male were 18-year-old. Nobody ever undergo a medical examination on fertility diagnosis.

Their findings showed that most, but not all, UV filter may be associated with loss of fertility in men, regardless of the exposure of their spouse. The researchers examined the impact among men who exposed very high (BP-2 or 4OH-BP) UV filter.

"In our study, male fertility seems to be easier to penetrated by these chemicals compared to the female fertility. Women participants actually have a greater exposure to the UV filter as a whole. However, their exposure was not associated with significantly pregnancy delay," said Germaine Louis, author of the study from the National Institutes of Health and Human Development Chile, part of the NIH, in a statement.

Louis also said people still encouraged to use the sunscreen to prevent skin cancer but men who are concerned about their fertility may try other ways to reduce their exposure to the benzophenone UV filter, such as washing themselves after the entry into the house. The researchers caution that the results are preliminary and additional studies are needed to confirm their findings.. *** [EKA | FROM VARIOUS SOURCES | ANTARA]
