Psst! Have your hair and your love life lost their luster?

According to Bolivian President Evo Morales, eating flesh from chickens that have been given female hormones could make men go bald and have "problems being men."

When chickens are given hormones, as they are in so many countries, it gives credibility to Morales' chrome-dome claim, and there are hard facts that eating meat causes impotence. And for another mood killer, if you catch your man rooting around in your bra drawer, it might be because he needs the support: Consuming meat and milk laced with estrogen and other hormones may contribute to the development of "moobs."

Thanks for your advice, Mr. President. For even more presidential advice on all things animal-related, pick up a copy of PETA President Ingrid E. Newkirk's latest book, The PETA Practical Guide to Animal Rights.

For a minute there, we thought Jeremy "Mercury Poisoning" Piven was serious when he said that he gave up soy milk for fear that it would give him "moobs."

I mean, come on, everybody knows that cow's milk—not soy milk—is the real culprit behind man boobs, right? According to Harvard scientist Ganmaa Davaasambuu, cow's milk "contains considerable amounts of female sex hormones"—especially milk from factory-farmed cows who are kept almost constantly pregnant. She estimates that dairy products account for 60 to 80 percent of the estrogens consumed by the average person.

But wait—there's more! Factory-farmed cows are commonly fed bovine growth hormone in order to stimulate their bodies to produce more milk. Hormone-treated cow's milk contains high levels of Insulin Growth Factor (IGF-1), which studies show can cause the dreaded gynecomastia (moobs). Milk consumption, with all its accompanying hormones, has also been linked to prostate cancer and breast cancer.

So, boys, if you're worried about maintaining your manly physique, pour some soy (or rice or almond) milk on your cereal—and pour the moob juice down the drain.

The following is a guest post from PETA Europe's Matt Goldsmith.

Always an organization to keep abreast of scientific studies, PETA Europe was particularly interested to learn that Glasgow, the city with the second-highest obesity rate of all the Organisation for Economic Co-operation and Development countries, has seen an 80 percent rise in gynecomastia (aka "Man Boob") reduction procedures since 2007.

Now, while there might be some men in the world who for various reasons would welcome the idea of growing a pair of breasts, at PETA Europe we know that only a boob would want to go out and buy a 44DD because of obesity helped along by eating foods derived from animals.

With our newest billboard, PETA Europe is calling on the men of Glasgow to make a difference—both for their bodies and for animals.

Lose the breasts, guys: Go vegetarian!
