I had never heard this before, so the information was quite astonishing to me. Just thought I'd pass this along.
It reminded me of the lavender and tea tree story.

A new study, published in Toxicology and Applied Pharmacology, has found that UV filters, known as benzophenone (BP) derivatives, act as endocrine disruptors. BP derivatives are found in chemical sunscreens, but are also found in many other personal products.
These BP derivatives can mimic the effect of the female hormone estrogen and interfere with the action of the male hormone, testosterone. The study found that these effects can be detected at levels found in human blood after applying sunscreen. Also, because these UV filters are by definition stable to light, they do not breakdown in sunlight, and therefore can bioaccumulate in the environment.
For sunblocks, an alternative to these chemical sunscreens are the physical sunblocks, which contain titanium dioxide or zinc oxide as the active ingredient. Physical sunblocks block or reflect light. An added bonus is that physical sunblocks don't kill coral reefs, unlike some chemical sunscreens. Make sure whatever sunblock you choose is a broad spectrum product that protects against UV-A and UV-B rays.
