I think it's pretty clear that Phthalates are a big piece of the puzzle. Here's the chain of evidence: I just picked one study for every link, but there are many for each. People have significant levels of Phthalates in their blood: http://www.ourstolenfuture.org/NewScience/oncompounds/phthal... People who have higher levels of Phthalates in their blood tend to have lower testosterone: http://www.medscape.com/viewart…

Have there been any studies on how to reduce phthalate levels in humans? Does limiting exposure help? Can the body expell the stuff?

I know of one, fairly questionable study that showed that you could reduce Phthalates in your blood by about 50% by eliminating processed food, never storing or heating food in plastic, and switching to Phthalate free personal care products. There have been a few studies that have shown that the main route of exposure is through ingestion. Processed foods are more likely to contain Phthalates, probably because the ingredients may have flowed through PVC tubing that leaches them. It's really impossible to know, but the fewer processing steps your food has gone through, the less chance that this has happened. The biggest industrial use of Phthalates is as a plasticizer, and they are present in several types of plastic, in large quantities. Heating food in plastic containers has the potential to volatilize Phthalates and leach them into your food. This is a particular risk in prepared frozen food that you microwave. Many personal care products, such as soaps, shampoos, deodorants, and perfumes, contain Phthalates. Try to find ones that don't.

One particularly bad source of exposure is certain enteric coated medicines and supplements. I would strongly advise anyone to not take anything that is enteric coated unless you know what the coating is made of. Some pills can spike Phthalate levels by 50x in a single dose.

Almost all foods that contain animal fat will contain Phthalates, and this is a big source of exposure. Milk, meat, cheese, etc, all contain them, as they are fat soluble. The good news is that your body seems to clear these chemicals fairly quickly, but the problem is that you're constantly exposed to them.

Ultimately, these are chemicals that we've produced over a billion tons of. It's just not possible to avoid them entirely. If you have a baby on the way though, make sure that the new mom does everything she can to minimize exposure, as what happens during that time really can never be taken back.

that sounds magical.

It is easily testable. Take samples of war veterans.

Not sure if it helps though. It has been so long since they have experienced a tough life, levels may already gone back to same levels as others.

What does Western Men means exactly? (I am from India so asking.) As every country has their own west. Does this mean West of US? Or West of whole world?

EU + USA

... + Canada + Australia

>birth control/estrogen in water Is that actually a thing? I didn't find any sources definitively showing it was enough to warrant a concern.

women take birth control they pee and flush this water gets processed and re injected back into the pipes if you make the mistake to drink the tap water where they re purpose it from the canalisations, you just drink birth control water.

Sounds like you have a local water supply problem if they serve you recycled sewage (or a regretful plumbing problem).

This is common among communities living on the Mississippi River, for example.

Gonna need some evidence to back that up. Wouldn't the treatment get rid of the birth control?

From what I was reading, this seems to be an anti-BC talking point, but I couldn't find any evidence to suggest that any estrogens in tap water is caused by BC.
