While sunscreen is essential in combating harmful UV rays that can cause skin cancer, a research from the University of Copenhagen in Denmark has raised warnings over men’s use of SPF creams.
As reported by Washington-based The Endocrine Society in April, a new study revealed that commonly used sunscreen ingredients may “disrupt sperm cell function.”
“These results are of concern and might explain in part why unexplained infertility is so prevalent,” expressed Dr. Niels Skakkebaek as he presented his findings at The Endocrine Society’s annual gathering held at Boston, Massachusetts.
Skakkebaek, study’s lead investigator, is also a researcher at the Copenhagen University Hospital.
According to his group’s findings, 13 out of 29 UV filters, or 45 percent of those tested induced calcium ion influxes in the sperm cells, thus interfering with normal sperm cell function.
What’s more is that UV filters are rapidly absorbed through the skin, as proven by the chemicals found in human blood samples and in 95 percent of urine samples in the US, Denmark and other countries, he said.
But Dr. Clarisse Mendoza, a fellow at the Philippine Dermatological Society, quickly debunked this study.
“They cannot focus it on just a sunscreen filter that is measly applied on the skin. It would require a big amount of sunscreen for it to be systemically absorbed and measured in the urine,” she told The Manila Times when asked for comments.
She added, “And lastly, in this day in age, there are a lot of factors in the environment that can contribute to infertility, like the kind of food we eat, radiation from gadgets that we are exposed to, or even the level of stress people handle.”
