NIH study links ultraviolet filters to pregnancy delays 
  
 Researchers identify two chemicals that appear to reduce fertility in men 
  
 Certain sunscreen chemicals used to protect against ultraviolent rays may impair men’s ability to father children in a timely manner, according to a study by the National Institutes of Health and the New York state Department of Health’s Wadsworth Center. But the researchers caution that the results are preliminary and that additional studies are needed to confirm their findings. 
  
 Benzophenone (BP)-type ultraviolet (UV) filters comprise a class of about 29 chemicals commonly used, among other purposes, in sunscreens and other personal care products to protect skin and hair from sun damage. Some of these chemicals, upon being absorbed by the skin, can interfere with the body’s hormones and endocrine system processes. Researchers found that men with high exposure to UV filters BP-2 or 4OH-BP had a 30 percent reduction in fecundity, the biological ability to reproduce. Lower fecundity may result in a longer time to pregnancy. 
  
 “In our study, male fecundity seems to be more susceptible to these chemicals than female fecundity. The women participants actually had greater exposure to the UV filters overall, but their exposure wasn’t associated with any significant pregnancy delays,” said Germaine Louis, Ph.D., director of the Division of Intramural Population Health Research at the Eunice Kennedy Shriver National Institute of Child Health and Human Development. “Our next step is to figure out how these particular chemicals may be affecting couple fecundity or time to pregnancy—whether it’s by diminishing sperm quality or inhibiting reproduction some other way.” 
  
 The study findings were published online in the American Journal of Epidemiology. 
  
 The researchers studied 501 couples that were trying to conceive a child. The couples were part of the Longitudinal Investigation of Fertility and the Environment (LIFE) study, established to examine relationships among fertility, lifestyle factors, and exposure to environmental chemicals. Researchers recruited the study participants from 16 counties in Michigan and Texas in 2005 through 2009. The women participants ranged from 18 to 44 years of age, and the men were over 18; none had a medical diagnosis of infertility. 
  
 The researchers followed the couples until pregnancy or up to one year of trying, to record the time it took for the women to become pregnant. They also tested participants’ urine samples and measured concentrations of five selected UV filters associated with endocrine-disrupting activity. In their data analysis, the researchers controlled for age, body mass index, and smoking, among other factors. 
  
 Their findings suggest that some, but not all, UV filters may be associated with diminished fertility in men, independent of their partners’ exposure. The researchers observed effects among men with the highest exposure (the 75th percentile and above) to UV filters BP-2 or 4OH-BP. 
  
 “The skin is the body’s largest organ, and how we care for our skin matters in more ways than one,” said Dr. Louis. “Sunscreen is important for sun protection, and we definitely encourage people to continue using sunscreen to avoid skin cancer. But men who are concerned about fertility may be interested in other ways to reduce their exposure to benzophenone UV filters—whether by cutting back on other products that contain the UV filters or by washing after returning indoors.” 
  
 Among the study’s major limitations: the researchers tested single urine samples from participants to assess chemical exposure, but participants’ levels of exposure may have changed over the course of trying for pregnancy. The researchers also had no data on what specific products the participants used that contained the UV filters. 
  
 Earlier research findings from the LIFE Study have linked reduced fertility to high cholesterol levels in women and couples and to high concentrations of phthalates and Bisphenol A (BPA) in men.

 NIH...Turning Discovery Into Health® ||||| Story highlights Study: Men with UV blocking products in their system had fertility challenges 
  
 There is no law mandating a product disclose it has this chemical in it 
  
 Be sure to wash off sunblock after a day in the sun 
  
 The cold snap that's hitting much of the country this week may leave you with a real desire to head to the beach. If you do, you may want to watch what kind of sunblock you use. 
  
 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. 
  
 Germaine Buck Louis, the lead author of the study, said there hasn't been much work done in this area. 
  
 "Right now, it's thought (these chemicals) are safe for use -- in preventing ionizing radiation and sunburn, but what about better health?" she asked. 
  
 She added that it is unclear exactly what role these chemicals may play in decreasing male fertility. 
  
 So what can you do if you want to keep your skin cancer-free, but are concerned about fertility issues? 
  
 The scientists say not much. There is no law that requires manufacturers to disclose the chemicals are in their products. They aren't on the ingredient list on the packaging. Buck said she believes that as more is learned about these chemicals and the unintended consequences they may have on your health, that may change. 
  
 Scientists say one thing to do is make sure you wash off the product after your day out in the sun. |||||
Output:
In the latest study proving everything in the world is dangerous, researchers are warning about a possible link between sunscreen and male fertility problems. The scientists investigated urine-sample data from 500 couples trying to have kids. They found that among couples taking the longest time to conceive, male partners had high levels of certain common sunscreen chemicals in their urine, CNN reports. Specifically, the guys showed high concentrations of the ultraviolet filters BP-2 or 4OH-BP, which are also found in shampoos and moisturizers. As for women, those in the study "actually had greater exposure to the UV filters overall, but their exposure wasn’t associated with any significant pregnancy delays," researcher Germaine Louis says in an NIH press release. Companies aren't legally required to list these chemicals in their products' ingredients, though lawmakers might take on the issue if further research confirms the findings, Louis says. Meanwhile, she clarifies her message: "We definitely encourage people to continue using sunscreen to avoid skin cancer. But men who are concerned about fertility may be interested in other ways to reduce their exposure to benzophenone UV filters—whether by cutting back on other products that contain the UV filters or by washing after returning indoors." (Another recent study found that macho men have so-so sperm.)
