ConclusionIn this comprehensive meta-analysis, sperm counts whether mea- sured by SC or TSC declined significantly among men from North America, Europe and Australia during 1973-2011, with a 50-60% decline among men unselected by fertility, with no evidence of a 'lev- eling off' in recent years. These findings strongly suggest a significant decline in male reproductive health, which has serious implications beyond fertility concerns. Research on causes and implications of this decline is urgently needed.

Doubt this is going to have major impacts on world fertility rates though. It's not like we're suddenly facing down a serious fertility crisis.

A lot more comes from natural and synthetic estrogens from livestock waste, from fertilizer, and from industrial shit like bisphenol-A and surfactants. EE2 is more potent, but the sheer volume of other estrogenic compounds compared to the small amount of EE2 makes me skeptical of laying the blame solely at the feet of the birth control pill.
just kidding, it's arsenic
