Hormones.
I just read Clement's blog and saw his tagboard was full of discussion about hormones. Interestingly, maybe the scientific community should do a full review on how hormones are used for anything at all.

Oestrogen-like compounds found in sunblock

"benzophenone-3, homosalate, 4-methyl-benzylidene camphor (4-MBC), octyl-methoxycinnamate and octyl-dimethyl-PABA - behaved like oestrogen in lab tests"

"When the team mixed it with olive oil and applied it to rat skin, it doubled the rate of uterine growth well before puberty. "That was scary, because we used concentrations that are in the range allowed in sunscreens," Schlumpf says. Nobody knows if doses are high enough to create problems for people, says Schlumpf."

Know what, now I'm sorta worried. Next time, when you get sunblock, try getting one that uses Zinc Oxide instead.

A Third of male fish in rivers change sex

What! 1/3 of fish changed sex. And there were also some that were neither gender, i.e. transvestites?

"British men's sperm counts dropped by almost a third between 1989 and 2002, and one in six couples now have difficulty conceiving."

Ok so now we sorta know why men these days have problems conceiving. Its probably due to high oestrogen levels in food we etat.

Alot of talk has centred around oestrogen found in soya bean and chicken (for tenderising of meat) and yes, it is a real danger that exists out there.

Plastics cause gender change

"These [oestrogen-mimicking compounds] are found in plastics, food packaging, shampoos and pesticides and accumulate in the environment. "

Ahh oestrogen is EVERYWHERE.

Now that we know a male fish treated with oestrogen can grow ovaries, what the heck are we doing to protect ourselves? O_O Now if we were dosed with oestrogen, would we grow ovaries? Maybe. But it has been proven that in men, testes would shrink and their female secondary characteristics would be enhanced (i.e. become a sissy).

Creepy huh. So the next time you see anything that says hormones present, think twice before using it.
