Researchers have found that 13 out of 29 UV filters used in sunscreens in the US and Europe can disrupt the function of human sperm cells - with some even mimicking the effect of the female hormone progesterone, and messing with sperm mobility.
So far, the UV filters have only been tested in human sperm cells in the lab, and not in live males, so there's no need to freak out, but it's a link that's worth investigating further.
