Hormones in Your Milk (Even Organic) Turn Men into Women

Almost all commercial dairies now market their milk as free of this synthetic hormone, but that label is hiding an important truth – your milk contains high levels of sex hormones such as estrogen.
  

The effect of milk on testosterone levels

Dairy milk accounts for about 80 percent of estrogen consumed through the human diet. And since all milk products are produces from pregnant cows, your milk contains about 33 times as much estrogen as milk from non-pregnant cows. From an economical standpoint, keeping dairy cows pregnant makes sense. Most of the milk you drink comes from cows that are kept pregnant for almost 300 days of the year. According to many studies, the milk of a cow that is at the late stages of pregnancy can contain up to 33 times more estrogen than that of non-pregnant cows.
  
 
Almost 60 different hormones can be found in cows milk. One study found that cows’ milk contains estrogens. Four samples of milk from non-pregnant cows were analyzed, free estrone were 23, 22, 27 and 24 pg mL, and values for total estrone were 162, 208, 174, and 243 pg mL. It gets better though, the estrogen levels in milk is even higher during pregnancy of a cow. Levels rose progressively during pregnancy from a mean value of 80-100 pg mL at 60-80 d of pregnancy to a value of around 1,000 pg mL.
Estradiol (pg/mL)                Progesterone (ng/mL)
Conventional milk                   4.97                             12.0
Organic milk                             6.40                            13.9
So that means you are consuming almost 1,000 pg mL of estrogen in that milk. Any amount of estrogen is bad but 1,000 pg mL is a nasty amount.
  
Drinking pregnant cows milk can account to a staggering 60-70% of our endogenous estrogen exposure.
Researchers have long noted that many types of hormone-related cancers, such as breast, testicular and prostate, are significantly higher in populations with high levels of milk and dairy consumption.
