Something in your sunblock may be causing fertility problems

A new study from the National Institutes of Health finds that chemicals in sunscreens and personal care products that filter out UV rays may lead to infertility issues among men. The study followed 500 couples who are part of a larger study known as the Longitudinal Investigation of Fertility and the Environment. This large study looks at the role between environmental chemicals and fertility. To get at this result, the authors took urine samples from the couples and had them keep a journal until they had conceived or had tried for 12 months. The couples who took the longest to conceive had something in common. BP-2 or 4OH-BP, two UV filter chemicals found commonly in sunblocks and sunscreens, were found in high concentrations in the male partner's urine. The chemicals are also used in moisturizers and shampoos. http://edition.cnn.com/2014/11/14/health/sunblock-fertility-problems/index.html?eref=edition
