Mom's beef puts son's sperm count at stake - Los Angeles Times

I wonder about all the other crap they feed cattle, chickens and fish.. Like the GMO's modified to like more pesticides. . .

Mom's beef puts son's sperm count at stake - Los Angeles Times: "Men whose mothers ate a lot of beef during their pregnancy have a sperm count about 25% below normal and three times the normal risk of fertility problems, researchers reported Tuesday.

The problem may be due to anabolic steroids used in the United States to fatten the cattle, Dr. Shanna H. Swan of the University of Rochester Medical Center reported in the journal Human Reproduction. It could also be due to pesticides and other environmental contaminants, she added.

If the sperm deficit is related to the hormones in beef, Swan's findings may be 'just the tip of the iceberg,' wrote biologist Frederick vom Saal of the University of Missouri-Columbia in an editorial accompanying the paper.

In daughters of the beef-eaters, those same hormones could alter the incidence of polycystic ovarian syndrome, the age of puberty and the postnatal growth rate, he said.

'It's a small effect, but it is a significant effect,' said Dr. Ted Schettler, an environmental health specialist at the Institute for Global Communications in San Francisco. 'It's not surprising. The more you look at dietary factors, the more you turn up interesting information about how diet during pregnancy affects lots of aspects of human health.'"
