Endocrine-disrupting xenoestrogens in fish may be interfering with male fertility.

Anyway, when you hear about environmental estrogens and male fertility, they’re not talking about phytoestrogens—plant estrogens. They’re talking about xenoestrogens—human-made chemicals, like PCBs and pesticides, that can have estrogenic effects. Where are they found the most? Fish.

So, it follows that the “highest…concentrations were found in urban fish eaters, followed by rural fish eaters, [then] urban vegetarians, [and with the lowest levels in] rural vegetarians.”

Here are the sperm counts: fish-eaters versus vegetarians.

To see any graphs, charts, graphics, images, and quotes to which Dr. Greger may be referring, watch the above video. This is just an approximation of the audio contributed by veganmontreal.
