A study demonstrated in 2016 that 13 out of 29 chemical UV filters mimic the Ca2+ signaling in human sperms by activating the progesterone pathway. This causes a Ca2+ imbalance in human sperm cells which directly affects its capacity to fertilize the egg.
All of these filters are allowed in the EU and/or US and they are typically found in sunscreens.
Some examples are avobenzone, octocrylene, octisalate or diethylamino hydroxybenzoyl hexylbenzoate, common UVA and UVB protectors.
Chemical UV filters mimic the effect of progesterone on Ca2+ signaling in human sperm cells. Rehfeld et al, Endocrinology 2016 Nov, 157(11), 4297-430.
