"By no means should sunscreen be avoided. It plays an important role in protecting us against skin cancer and should be used along with other filters for UV rays, such as light clothing, sun shades and hats when exposed to the bright sun. But for people hoping to have a child, avoiding these chemicals is something that should be considered" Dr. Adamson (National Institutes of Health (NIH) and the Department of Health's Wadsworth Center in New York). A preliminary study conducted in the NIH (USA), revealed that the chemicals found in sunscreens, especially benzophenone (BP) type ultraviolet (UV) filters, and other cosmetic products may cause male infertility. The myth about infertility being a female's issue still prevails but it must be known that it affects the male species as well. Sunscreens include around 30 different chemicals that causes a 30 percent decline in the biological capability of man to reproduce. It was also found that male fecundity was more vulnerable when compared to female fecundity. (Germaine Louis, director of the Division of Intramural Population Health Research at the Eunice Kennedy Shriver National Institute of Child Health and Human Development) Researchers discovered that men, who were highly exposed to UV filters 4OH-BP or BP-2, had a 30 percent decline in fecundity, which is the biological capability of a person to reproduce. The scientists suggest that lower fecundity in men can result in a longer time period for their partner to get pregnant. The increase in skin cancer prevalence and the increase of melanoma rate has tripled in the last three decades, is the reason individuals have stared using sunscreen and it is beneficial for us, but one should use it in proper proportions and in varied methods. One must also refer to a physician before using skin / cosmetic products.
