Sunscreen Linked To Infertility In Men


Certain chemicals in sunscreens and other personal care items might be linked to infertility in men, according to a study conducted by the National Institute of Health and the New York State Department of Health’s Wadsworth Center.

The study followed 500 couples and noted the role between environmental chemicals and fertility. To get an exact result in regard to sunscreen, researchers took urine samples from each couple and required each participant to keep a diary for twelve months or until they conceived.

The couples who took the longest to conceive were all found to have high concentrations of two UV filter chemicals (BP-2 and 4OH-BP) in their urine, particularly the men. The same chemicals are found in moisturizers and shampoos.

Interestingly, women were found to have higher contact rates with UV filters than man, though their association with the product had no effect on their ability to conceive.

Despite the findings, lead researcher and author of the study Germaine Buck Louis said there hasn’t been much work done in the area of the chemicals and their connection to infertility.

“Right now, it’s thoughts [these chemicals] are safe for use – in preventing ionizing radiation and sunburn, but what about better health?” Louis said.

Louis added that it’s unclear what roles the chemicals play exactly in the issue of decreased male fertility. To further prevent such an occurrence, Louis noted that there isn’t much consumers can currently do, since manufacturers aren’t legally required to disclose the chemicals in their products. However, she argued that once more is known about UV filter chemicals and their unintended consequences, that might change.

Researchers have advised those who use sunscreen to wash off the product once the threat of the sun is gone.

Scientists noted that the study is purely preliminary and that further research is required on the topic before the findings can be confirmed.
