A new study claims that sunscreen could be the culprit of infertility issues with men. Reports about this research published by the University of Copenhagen started to make rounds on April 2.
Headline & Global News posted that some ingredients of these sunscreen products from Europe and the U.S are the ones causing sperms to not function well. Scientists of this study sampled 29 sunscreens that are legally sold in Europe and America and found out that some of its ingredients are hindering the calcium ion that works in sperm cells.

Basically, a calcium ion channel called the CatSper that works specifically in sperm cells is being hindered by the UV filters in sunscreens to work. This channel is crucial for sperms to function accordingly because they act as a receptor for the hormone progesterone. The Inquisitr wrote that due to the chemicals found in sunscreens, CatSper and progesterone get to entwine with each other. When that happens, calcium ions experience a temporary reflux, which results in infertility.
The head of this project, Dr. Niels Skakkebaek said, "These results are of concern and might explain in part why unexplained infertility is so prevalent." The main goal of UV filters found in sunscreens is to block the UV rays coming from the sun. The problem is that the skin easily absorbs most of these filters that they go straight to the blood and even a person's urine.
Science Daily reported that 95 percent of urine samples in America and some countries in Europe have UV filters in them. Scientists are warning men through this study saying that their skin is not the only part that absorbs the UV filters in sunscreens, but the whole body.
Contrary to popular belief that sunscreens could help you prevent from getting skin cancer, apparently it even contributes to cancer growth. SunWarrior shared this information and suggests that both men nd women just find some natural alternatives to protect the skin from the harmful rays of the sun.
